Action Requested of the Board of Supervisors The Board is requested to conduct a public hearing on the proposed Coastal Permit for the Coastal Prairie Trail At the conclusion of the hearing your Board may approve the Coastal Permit as recommended by staff Prior Actions A Mitigated Negative Declaration was previously adopted by the Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Mitigated Negative Declaration was prepared by the Sonoma County Regional Parks Department Subsequent to adopting the Mitigated Negative Declaration a Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project dated February 2012 was prepared by Jane Valerius to clarify the location of the wetland and riparian mitigation enhancement The Coastal Permit application was submitted on July 16 2009 and was deemed complete on December 19 2011 On May 15 2012 the Board of Supervisors took original jurisdiction on the proposed project as requested by the Permit and Resource Management Department (PRMD) On June 9 2012 staff sent out a Notice of Public Hearing ndash Pending Action on a Coastal Permit to surrounding neighbors and posted the Notice on and near the project site Location Zoning and Project Description Location The Coastal Prairie Trail project will be located on eight contiguous properties owned by the County of Sonoma and the State of California The parcels are located between Bay Hill Road and Keefe Avenue in Bodega Bay (a one mile route from 2255 Highway 1 to 100 Keefe Ave Bodega Bay) The base zoning for all parcels is PF (Public Facilities) and combining zones are CC (Coastal Combining) SR (Scenic Resources) and G (Geologic Hazard Area) The project area is bordered by Sonoma Coast State Park and Bodega Dunes Campground to the west and State Highway 1 to the east The Salmon Creek residential community is located on the northern boundary just beyond the proposed parking area off Keefe Avenue The southern boundary is bordered by County of Sonoma properties which is where the Bodega Bay Community Center and the Nicholas Green Memorial Bell Tower are located

June 19 2012 File No CPH09-007 Page 2 The Bodega Bay RV Park is located along the southern boundary of the Bodega Bay Community Center property Approximately 300-feet of shoulder along the east side of State Highway 1 will be widened for the proposed State Highway 1 improvement near the south driveway that serves the trailhead The area of the shoulder widening is generally within property owned by Caltrans and is bordered by private residential property The project area and vicinity includes a vast array of biological resources including upland and wetland plant communities that provide habitat to many wildlife species some of which are sensitive species The project area is a mosaic of habitats including coastal terrace prairie northern coastal scrub and wetlands typical of the Sonoma County coastal environment An unnamed stream traverses one of the State Parks properties and is surrounded by dense riparian vegetation The project area also includes stands of Monterey cypress eucalyptus and Monterey pine A bridge is intended to cross a USGS mapped stream channel located on the project site This stream is unnamed It originates on the east side of Highway 1 between two saddles on the northern slope of Mount Roscoe and flows in an east-west direction parallel to the entrance road to the Bodega Dunes State Park within State Parks property Within the project area the stream empties into a large palustrine emergent wetland and is surrounded by the Arroyo Willow plant community Ultimately the stream drains further into two basins within coastal dune habitat on State Parks property Trail Improvements The proposed project is a request for a Coastal Permit to construct a trail known as the Coastal Prairie Trail The trail is designed as a Class 1 bike path and will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian uses The trail will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rock aggregated shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side the three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trail will consist of approximately 918 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge over the unnamed tributary Bridge Improvements A pre-fabricated wooden-deck bridge will be installed over the unnamed tributary that flows through one of the State Parks properties The bridge will be single-span and 120-feet in length and 8-feet in width The bridge will include boardwalk approaches each 32-foot long and 8-foot wide on both ends of the bridge to complete the span over the tributary and 12-foot by 10-foot concrete landing pads on both ends of the boardwalk sections Parking Improvements The trailhead will be located approximately half-way along the trail approximately 010 mile south of State Parkrsquos Bodega Dunes Campground entrance road off State Highway 1 The trailhead will include a parking area accessed from a paved entrance a screened portable restroom picnic tables bicycle rack trash cans and other amenities The trailhead parking area will accommodate approximately 15 passenger vehicles including one van accessible disabled parking space in compliance with ADA requirements The trailhead parking area will include access for school and public transit busses as well as emergency access vehicles Additional parking for seven vehicles including one ADA-compliant parking space will be provided at the northern terminus of the Coastal Prairie Trail at Keefe

June 19 2012 File No CPH09-007 Page 3 Avenue A wildlife-friendly vehicle barrier consisting of logs and bollards will be placed around the parking areas so that vehicles cannot drive onto the trail itself State Highway 1 Improvements A 300-foot section of shoulder along the east side of Highway 1 will be widened to provide an 8-foot paved width across from the access driveway to the trailhead parking area The paved shoulder will include 50-foot long tapered ends on both sides The purpose is to provide an area to pass vehicles making the left turn into the trailhead parking area This improvement will occur on both sides of the Caltrans maintenance facility driveway on an existing Caltrans easement The project will also include installation of two culverts on the south side of the Bodega Dunes Campground entry road interpretive and operational signage along the trail and relocation of one PGampE utility pole along State Highway 1 Purpose and Need for the Project Project Purpose The purpose of the proposed project is to develop a section of Class I bicycle path along State Highway 1 to provide a safe travel way separate from the State highway The Class I bicycle path will be multi-use for bicycle pedestrian and equestrian use Currently the only path for non-motorized use along this section of State Highway 1 is a very narrow section of paved shoulder immediately adjacent to the vehicle travel lane Development of the Coastal Prairie Trail is expected to encourage alternatives to motorized travel between existing residential recreational and commercial areas in Bodega Bay and reduce traffic congestion Project Need The development of a continuous trail through the unincorporated Town of Bodega Bay and the immediate surrounding area has long been a community goal Topographic and land use constraints have presented numerous challenges to the development of such a trail Long stretches of Highway 1 cut through the center of town These stretches have little to no road shoulder because of existing right-of-way vegetation and topography Numerous residential structures have been built alongside Highway 1 creating sight distance problems around curves and leaving little room to walk bicycle ride horses or use any form of alternative transportation The existing condition forces non-motorized travelers onto the narrow shoulders along Highway 1

DISCUSSION OF ISSUES

Issue 1 General Plan Consistency The General Plan land use designation for the subject parcel is PQP (Public and Quasi Public) General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs and owned or operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

June 19 2012 File No CPH09-007 Page 4 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks and the new trail will benefit and be used by the general public General Plan Policy OSRC-17d of the Open Space and Resource Conservation defines the ldquoSonoma Coast Trailrdquo as extending from Black Point to the Estero Americano and finds the trail consistent with the California State Coastal Plan Policy 145 that calls for the establishment of a statewide coastal trail system This General Plan Policy also states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and the Coastal Prairie Trail is a segment of the Sonoma Coast Trail General Plan Policy CT-3v of the Circulation and Transit Element states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public General Plan Policy CT-3q of the Circulation and Transit Element states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeways Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail As conditioned the proposed project is consistent with the goals objectives and policies of the General Plan Issue 2 Local Coastal Plan Consistency The Local Coastal Plan land use designation for the subject site is Institutional and Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located on two public parks and the new trail will benefit and be used by the general public The proposed project is consistent with the Coastal Land Use designation of Institutional The Recreation Resources section of the Local Coastal Plan per section V-3 requires the following development criteria for coastal access trails

Among the facilities needed for access ways and shoreline destinations are safe trails restrooms parking areas trash receptacles and signs Necessary facilities at a particular site will depend upon expected use and the availability of facilities nearby

The Coastal Prairie Trail is designed as a Class 1 bike path and will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian uses and provides coastal access to the public Restroom facilities and trash receptacles will be located at the south trailhead Adequate parking areas and trail signs will be located at the south and north trailheads The proposed project is consistent with the Recreation Resources section of the Local Coastal Plan Issue 3 Coastal Zoning Ordinance Consistency The Coastal Zoning designation for the subject parcels is PF (Public Facilities) CC (Coastal Combining District) G (Geologic Hazard) SR (Scenic Resource Combining District) Section 26C-182(a) of the

June 19 2012 File No CPH09-007 Page 5 Public Facilities Zoning district allows any facility owned and operated by a city or the county as an allowed use without a Use Permit The proposed project will not have an effect on a Scenic Resource Combining District as the facilities will be screened by existing vegetation and natural terrain The materials used will blend in with the native surroundings as the aggregate used for the trail surface will be tinted an earth tone color and wood will be used for the boardwalks and bridge The trail will be constructed at grade following natural contours of the land The trailhead parking area accessed from Highway 1 will be well screened by existing vegetation Issue 4 Environmentally Sensitive Habitat Areas Wetlands The following policies from the Environmental Resources section of the Sonoma County Local Coastal Plan apply to the proposed project

Section III-1of the Local Coastal Plan

30233 (a) The diking filling or dredging of open coastal waters wetlands estuaries and lakes shall be permitted in accordance with other applicable provisions of this division where there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects and shall be limited to the following

(7) Nature study aquaculture or similar resource-dependent activities

(c) In addition to the other provisions of this section diking filling or dredging in existing estuaries and wetlands shall maintain or enhance the functional capacity of the wetland or estuary Any alteration of coastal wetlands identified by the Department of Fish and Game including but not limited to the 19 coastal wetlands identified in its report entitled Acquisition Priorities for the Coastal Wetlands of California shall be limited to very minor incidental public facilities restorative measures nature study commercial fishing facilities in Bodega Bay and development in already developed parts of south San Diego Bay if otherwise in accordance with this division

This Section of the Coastal Plan allows filling of wetlands when there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects provided the use is nature study aquaculture or similar resource-dependent activities In addition this Section limits the fill of a wetland to very minor incidental public facilities The proposed project has been designed to avoid and minimize damage to wetlands Permanent impacts to the wetlands would be from the boardwalk footings and regular trail sections To offset the loss of the wetland Regional Parks is proposing to enhance the on-site existing wetland at a 31 ratio (see discussion listed below Issue 5) The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access In addition the Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system

June 19 2012 File No CPH09-007 Page 6

Section III-2 of the Local Coastal Plan

30240 (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat values and only uses dependent on such resources shall be allowed within such areas

(b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation areas shall be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of such habitat areas

Wetlands are considered environmentally sensitive habitats in the Local Coastal Plan The trail has been designed to minimize impacts to existing wetlands as the impacts will occur to low quality wetlands The applicant is proposing to enhance on-site wetland habitat values at a 31 which is equal to approximately 417 acres of enhancement (see additional discussion listed below Issue 5) In addition a 185 acre of wetland enhancement will also take place on-site Section III-13 of the Local Coastal Plan

(24) Prohibit the removal of vegetation from wetlands unless it is shown to be essential to the habitat viability

(25) Prohibit construction of agricultural commercial industrial and residential structures within 100 feet of wetlands

(26) Between 100 and 300 feet of wetlands prohibit construction of agricultural commercial industrial and residential structures unless an environment assessment finds the wetland would not be affected by such construction

As previously stated the on-site wetland habitat will be enhanced at a 31 ratio and the proposed use is not an agricultural commercial industrial or residential the use is considered a recreational use The trail is a resource-dependent use as the nature trail provides coastal access to the public Riparian Habitat

Section III-12 Local Coastal Plan

(9) Prohibit construction of permanent structures within riparian areas as defined or 100 feet from the lowest line of riparian vegetation whichever is greater except development dependent on there sources in the riparian habitat including public recreation facilities related to the resource Any development shall be allowed only if it can be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of the riparian habitat The riparian area or 100 foot wide buffer zone should generally be maintained in a natural undisturbed state Trails and access may be permitted if studies determine no long-term adverse impacts would result from their construction maintenance and public use Trails should be made of porous materials

This Section from the Local Coastal Plan allows development to encroach within the 100-foot riparian setback provided the project is sited and designed to prevent impacts which would significantly degrade the riparian habitat Trails and access is permitted if studies determine there is no long-term adverse impacts due to construction maintenance and public use

June 19 2012 File No CPH09-007 Page 7 The proposed project includes a bridge with a wooden-deck to be installed over an unnamed tributary that flows through one of the State Parks properties (north of Bodega Dunes State Park) The 120-foot long bridge will minimize impacts to the surrounding willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only due to the removal of approximately 20 square feet of willowswoodlandriparian plants The Wetland Mitigation Enhancement and Habitat Restoration Plan requires native trees and shrubs be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement Issue 5 Impacts on Wetlands The proposed project will create temporary and permanent impacts to wetland habitat Temporary impacts will be the result of construction activities The wetlands under federal jurisdiction and those are state jurisdiction are located on the proposed trail and adjacent east and west side of the trail In the federal wetlands permanent impacts would be from the boardwalk footings In the state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections The boardwalks themselves will not result in permanent impacts to either federal or state wetlands because they will either be avoided or minimized as a result of the placement of boardwalks Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks are proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only State Wetlands Wetland areas under California Coastal Commission (CCC) jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock-aggregate shoulders Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub This area was likely coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhancement is to eliminate the invading coyote bush iceplant and non-native grasses and increase the native species cover and re-establish the coastal prairie community type The purpose and goal of

June 19 2012 File No CPH09-007 Page 8 enhancing the existing coastal scrub community by converting it to a native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition The proposed project will create the following temporary and permanent impacts to wetlands located on the project site Temporary Impacts Permanent Impacts Federal Wetlands 039 acres temporary impacts +-0003 acres permanent impacts (17080 square feet) (1410 square feet) State Wetlands 329 acres temporary impacts 139 acres permanent impacts (143314 square feet) (60436 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project (prepared by Jane Valerius dated February 2012) provides a Wetland Mitigation Enhancement Plan for the proposed project to compensate for the permanent loss of wetland habitat The Wetland Mitigation Enhancement Plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within United States Army Corps of Engineers (Army Corps) wetland areas The mitigation measures for the Mitigated Negative Declaration and the Wetland Mitigation Enhancement Plan are included in the conditions of approval The Wetland Mitigation Enhancement and Habitat Restoration Plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures will be conducted by Sonoma County Regional Parks to compensate for the permanent and temporary impacts to wetlands and riparian habitat 1 Enhance existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional

wetlands resulting in a minimum of 417 acres of wetland enhancement 2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses 3 Direct seeding the temporary construction areas with a seed mix based on the native grasses

forbs and flowers disturbed to construct the project 4 Direct seeding from seed and mulching of temporary construction areas along the trail and at

staging areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on-site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting

native trees and shrubs 6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct

seeding of native coastal prairie species south of the Bodega Dunes Park entrance road 7 Monitoring and following performance criteria for wetland enhancement for a minimum of three

years after all seeding planting and weed control activities have been completed

June 19 2012 File No CPH09-007 Page 9

In addition to the 417 acre of wetland enhancement listed above another 185 acre of wetland enhancement will also take place on-site The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Army Corps and Regional Water Quality Control Board (RWQCB) by January 31st of each year The first year annual report will be submitted after the first growing season after planting The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites Issue 6 Impacts on Riparian Habitat The proposed project will create temporary and permanent impacts to riparian habitat Temporary impacts are associated with construction activities and the areas will be restored to their pre-construction condition after construction activities are complete Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community at this location The proposed project will create the following temporary and permanent impacts to riparian habitat located on the project site Temporary Impacts Permanent Impacts Arroyo Willow temporary impacts 0022 acres permanent impacts 00003 acres Riparian Woodland (962 square feet) (126 square feet) Arroyo Willow temporary impacts 0015 acres permanent impacts 00002 acres Sedge Woodland (660 square feet) (70 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The previously mentioned Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project also provides a riparian mitigation enhancement plan for the proposed project to compensate for the permanent loss of riparian habitat The plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures that are included in the condition of approval 1 Plant native trees and shrubs at a 31 ratio based on trees removed from the riparian areas that

have a breast-height diameter of 6-inches or greater resulting in a minimum of 55 acres of riparian enhancement In the case of removal of non-native species a suitable native species will be selected for replanting

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

The following provides the methods and treatments to be applied to the enhancement and restoration sites for mitigation of both permanent and temporary impacts from the proposed project Table 1 provides a list of plant species-that will be used for seeding and planting for wetland mitigation enhancement and grassland habitat restoration The species on the list are based on the plant surveys conducted for the project and all these species occur within the trail alignment

Figures 1 and 2 show the location of the mitigation sites and the associated existing plant community types along the trail Figures 3 and 4 show the plant species recommended for seeding All figures are provided as attachments at the end of this report Photographs of Sites A Band C are provided in Appendix A

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Planting Stock Container plants if any are installed will have a 90 survival rate for the first year and 80 for the second year with 75 for the third year

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 eviderice of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or no new growth apparent 5 healthy vigorous new growth

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

DATE June 19 2012 at 210 pm TO Board of Supervisors FROM Cynthia Demidovich Project Planner SUBJECT Hearing to consider a Coastal Permit for the Sonoma County Regional Parks

proposed Bodega Bay Coastal Prairie Trail Project CPH09-0007 Sonoma County Regional Parks Supervisorial District No 5

Action Requested of the Board of Supervisors The Board is requested to conduct a public hearing on the proposed Coastal Permit for the Coastal Prairie Trail At the conclusion of the hearing your Board may approve the Coastal Permit as recommended by staff Prior Actions A Mitigated Negative Declaration was previously adopted by the Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Mitigated Negative Declaration was prepared by the Sonoma County Regional Parks Department Subsequent to adopting the Mitigated Negative Declaration a Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project dated February 2012 was prepared by Jane Valerius to clarify the location of the wetland and riparian mitigation enhancement The Coastal Permit application was submitted on July 16 2009 and was deemed complete on December 19 2011 On May 15 2012 the Board of Supervisors took original jurisdiction on the proposed project as requested by the Permit and Resource Management Department (PRMD) On June 9 2012 staff sent out a Notice of Public Hearing ndash Pending Action on a Coastal Permit to surrounding neighbors and posted the Notice on and near the project site Location Zoning and Project Description Location The Coastal Prairie Trail project will be located on eight contiguous properties owned by the County of Sonoma and the State of California The parcels are located between Bay Hill Road and Keefe Avenue in Bodega Bay (a one mile route from 2255 Highway 1 to 100 Keefe Ave Bodega Bay) The base zoning for all parcels is PF (Public Facilities) and combining zones are CC (Coastal Combining) SR (Scenic Resources) and G (Geologic Hazard Area) The project area is bordered by Sonoma Coast State Park and Bodega Dunes Campground to the west and State Highway 1 to the east The Salmon Creek residential community is located on the northern boundary just beyond the proposed parking area off Keefe Avenue The southern boundary is bordered by County of Sonoma properties which is where the Bodega Bay Community Center and the Nicholas Green Memorial Bell Tower are located

June 19 2012 File No CPH09-007 Page 2 The Bodega Bay RV Park is located along the southern boundary of the Bodega Bay Community Center property Approximately 300-feet of shoulder along the east side of State Highway 1 will be widened for the proposed State Highway 1 improvement near the south driveway that serves the trailhead The area of the shoulder widening is generally within property owned by Caltrans and is bordered by private residential property The project area and vicinity includes a vast array of biological resources including upland and wetland plant communities that provide habitat to many wildlife species some of which are sensitive species The project area is a mosaic of habitats including coastal terrace prairie northern coastal scrub and wetlands typical of the Sonoma County coastal environment An unnamed stream traverses one of the State Parks properties and is surrounded by dense riparian vegetation The project area also includes stands of Monterey cypress eucalyptus and Monterey pine A bridge is intended to cross a USGS mapped stream channel located on the project site This stream is unnamed It originates on the east side of Highway 1 between two saddles on the northern slope of Mount Roscoe and flows in an east-west direction parallel to the entrance road to the Bodega Dunes State Park within State Parks property Within the project area the stream empties into a large palustrine emergent wetland and is surrounded by the Arroyo Willow plant community Ultimately the stream drains further into two basins within coastal dune habitat on State Parks property Trail Improvements The proposed project is a request for a Coastal Permit to construct a trail known as the Coastal Prairie Trail The trail is designed as a Class 1 bike path and will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian uses The trail will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rock aggregated shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side the three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trail will consist of approximately 918 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge over the unnamed tributary Bridge Improvements A pre-fabricated wooden-deck bridge will be installed over the unnamed tributary that flows through one of the State Parks properties The bridge will be single-span and 120-feet in length and 8-feet in width The bridge will include boardwalk approaches each 32-foot long and 8-foot wide on both ends of the bridge to complete the span over the tributary and 12-foot by 10-foot concrete landing pads on both ends of the boardwalk sections Parking Improvements The trailhead will be located approximately half-way along the trail approximately 010 mile south of State Parkrsquos Bodega Dunes Campground entrance road off State Highway 1 The trailhead will include a parking area accessed from a paved entrance a screened portable restroom picnic tables bicycle rack trash cans and other amenities The trailhead parking area will accommodate approximately 15 passenger vehicles including one van accessible disabled parking space in compliance with ADA requirements The trailhead parking area will include access for school and public transit busses as well as emergency access vehicles Additional parking for seven vehicles including one ADA-compliant parking space will be provided at the northern terminus of the Coastal Prairie Trail at Keefe

June 19 2012 File No CPH09-007 Page 3 Avenue A wildlife-friendly vehicle barrier consisting of logs and bollards will be placed around the parking areas so that vehicles cannot drive onto the trail itself State Highway 1 Improvements A 300-foot section of shoulder along the east side of Highway 1 will be widened to provide an 8-foot paved width across from the access driveway to the trailhead parking area The paved shoulder will include 50-foot long tapered ends on both sides The purpose is to provide an area to pass vehicles making the left turn into the trailhead parking area This improvement will occur on both sides of the Caltrans maintenance facility driveway on an existing Caltrans easement The project will also include installation of two culverts on the south side of the Bodega Dunes Campground entry road interpretive and operational signage along the trail and relocation of one PGampE utility pole along State Highway 1 Purpose and Need for the Project Project Purpose The purpose of the proposed project is to develop a section of Class I bicycle path along State Highway 1 to provide a safe travel way separate from the State highway The Class I bicycle path will be multi-use for bicycle pedestrian and equestrian use Currently the only path for non-motorized use along this section of State Highway 1 is a very narrow section of paved shoulder immediately adjacent to the vehicle travel lane Development of the Coastal Prairie Trail is expected to encourage alternatives to motorized travel between existing residential recreational and commercial areas in Bodega Bay and reduce traffic congestion Project Need The development of a continuous trail through the unincorporated Town of Bodega Bay and the immediate surrounding area has long been a community goal Topographic and land use constraints have presented numerous challenges to the development of such a trail Long stretches of Highway 1 cut through the center of town These stretches have little to no road shoulder because of existing right-of-way vegetation and topography Numerous residential structures have been built alongside Highway 1 creating sight distance problems around curves and leaving little room to walk bicycle ride horses or use any form of alternative transportation The existing condition forces non-motorized travelers onto the narrow shoulders along Highway 1

DISCUSSION OF ISSUES

Issue 1 General Plan Consistency The General Plan land use designation for the subject parcel is PQP (Public and Quasi Public) General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs and owned or operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

June 19 2012 File No CPH09-007 Page 4 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks and the new trail will benefit and be used by the general public General Plan Policy OSRC-17d of the Open Space and Resource Conservation defines the ldquoSonoma Coast Trailrdquo as extending from Black Point to the Estero Americano and finds the trail consistent with the California State Coastal Plan Policy 145 that calls for the establishment of a statewide coastal trail system This General Plan Policy also states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and the Coastal Prairie Trail is a segment of the Sonoma Coast Trail General Plan Policy CT-3v of the Circulation and Transit Element states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public General Plan Policy CT-3q of the Circulation and Transit Element states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeways Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail As conditioned the proposed project is consistent with the goals objectives and policies of the General Plan Issue 2 Local Coastal Plan Consistency The Local Coastal Plan land use designation for the subject site is Institutional and Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located on two public parks and the new trail will benefit and be used by the general public The proposed project is consistent with the Coastal Land Use designation of Institutional The Recreation Resources section of the Local Coastal Plan per section V-3 requires the following development criteria for coastal access trails

Among the facilities needed for access ways and shoreline destinations are safe trails restrooms parking areas trash receptacles and signs Necessary facilities at a particular site will depend upon expected use and the availability of facilities nearby

The Coastal Prairie Trail is designed as a Class 1 bike path and will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian uses and provides coastal access to the public Restroom facilities and trash receptacles will be located at the south trailhead Adequate parking areas and trail signs will be located at the south and north trailheads The proposed project is consistent with the Recreation Resources section of the Local Coastal Plan Issue 3 Coastal Zoning Ordinance Consistency The Coastal Zoning designation for the subject parcels is PF (Public Facilities) CC (Coastal Combining District) G (Geologic Hazard) SR (Scenic Resource Combining District) Section 26C-182(a) of the

June 19 2012 File No CPH09-007 Page 5 Public Facilities Zoning district allows any facility owned and operated by a city or the county as an allowed use without a Use Permit The proposed project will not have an effect on a Scenic Resource Combining District as the facilities will be screened by existing vegetation and natural terrain The materials used will blend in with the native surroundings as the aggregate used for the trail surface will be tinted an earth tone color and wood will be used for the boardwalks and bridge The trail will be constructed at grade following natural contours of the land The trailhead parking area accessed from Highway 1 will be well screened by existing vegetation Issue 4 Environmentally Sensitive Habitat Areas Wetlands The following policies from the Environmental Resources section of the Sonoma County Local Coastal Plan apply to the proposed project

Section III-1of the Local Coastal Plan

30233 (a) The diking filling or dredging of open coastal waters wetlands estuaries and lakes shall be permitted in accordance with other applicable provisions of this division where there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects and shall be limited to the following

(7) Nature study aquaculture or similar resource-dependent activities

(c) In addition to the other provisions of this section diking filling or dredging in existing estuaries and wetlands shall maintain or enhance the functional capacity of the wetland or estuary Any alteration of coastal wetlands identified by the Department of Fish and Game including but not limited to the 19 coastal wetlands identified in its report entitled Acquisition Priorities for the Coastal Wetlands of California shall be limited to very minor incidental public facilities restorative measures nature study commercial fishing facilities in Bodega Bay and development in already developed parts of south San Diego Bay if otherwise in accordance with this division

This Section of the Coastal Plan allows filling of wetlands when there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects provided the use is nature study aquaculture or similar resource-dependent activities In addition this Section limits the fill of a wetland to very minor incidental public facilities The proposed project has been designed to avoid and minimize damage to wetlands Permanent impacts to the wetlands would be from the boardwalk footings and regular trail sections To offset the loss of the wetland Regional Parks is proposing to enhance the on-site existing wetland at a 31 ratio (see discussion listed below Issue 5) The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access In addition the Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system

June 19 2012 File No CPH09-007 Page 6

Section III-2 of the Local Coastal Plan

30240 (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat values and only uses dependent on such resources shall be allowed within such areas

(b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation areas shall be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of such habitat areas

Wetlands are considered environmentally sensitive habitats in the Local Coastal Plan The trail has been designed to minimize impacts to existing wetlands as the impacts will occur to low quality wetlands The applicant is proposing to enhance on-site wetland habitat values at a 31 which is equal to approximately 417 acres of enhancement (see additional discussion listed below Issue 5) In addition a 185 acre of wetland enhancement will also take place on-site Section III-13 of the Local Coastal Plan

(24) Prohibit the removal of vegetation from wetlands unless it is shown to be essential to the habitat viability

(25) Prohibit construction of agricultural commercial industrial and residential structures within 100 feet of wetlands

(26) Between 100 and 300 feet of wetlands prohibit construction of agricultural commercial industrial and residential structures unless an environment assessment finds the wetland would not be affected by such construction

As previously stated the on-site wetland habitat will be enhanced at a 31 ratio and the proposed use is not an agricultural commercial industrial or residential the use is considered a recreational use The trail is a resource-dependent use as the nature trail provides coastal access to the public Riparian Habitat

Section III-12 Local Coastal Plan

(9) Prohibit construction of permanent structures within riparian areas as defined or 100 feet from the lowest line of riparian vegetation whichever is greater except development dependent on there sources in the riparian habitat including public recreation facilities related to the resource Any development shall be allowed only if it can be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of the riparian habitat The riparian area or 100 foot wide buffer zone should generally be maintained in a natural undisturbed state Trails and access may be permitted if studies determine no long-term adverse impacts would result from their construction maintenance and public use Trails should be made of porous materials

This Section from the Local Coastal Plan allows development to encroach within the 100-foot riparian setback provided the project is sited and designed to prevent impacts which would significantly degrade the riparian habitat Trails and access is permitted if studies determine there is no long-term adverse impacts due to construction maintenance and public use

June 19 2012 File No CPH09-007 Page 7 The proposed project includes a bridge with a wooden-deck to be installed over an unnamed tributary that flows through one of the State Parks properties (north of Bodega Dunes State Park) The 120-foot long bridge will minimize impacts to the surrounding willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only due to the removal of approximately 20 square feet of willowswoodlandriparian plants The Wetland Mitigation Enhancement and Habitat Restoration Plan requires native trees and shrubs be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement Issue 5 Impacts on Wetlands The proposed project will create temporary and permanent impacts to wetland habitat Temporary impacts will be the result of construction activities The wetlands under federal jurisdiction and those are state jurisdiction are located on the proposed trail and adjacent east and west side of the trail In the federal wetlands permanent impacts would be from the boardwalk footings In the state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections The boardwalks themselves will not result in permanent impacts to either federal or state wetlands because they will either be avoided or minimized as a result of the placement of boardwalks Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks are proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only State Wetlands Wetland areas under California Coastal Commission (CCC) jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock-aggregate shoulders Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub This area was likely coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhancement is to eliminate the invading coyote bush iceplant and non-native grasses and increase the native species cover and re-establish the coastal prairie community type The purpose and goal of

June 19 2012 File No CPH09-007 Page 8 enhancing the existing coastal scrub community by converting it to a native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition The proposed project will create the following temporary and permanent impacts to wetlands located on the project site Temporary Impacts Permanent Impacts Federal Wetlands 039 acres temporary impacts +-0003 acres permanent impacts (17080 square feet) (1410 square feet) State Wetlands 329 acres temporary impacts 139 acres permanent impacts (143314 square feet) (60436 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project (prepared by Jane Valerius dated February 2012) provides a Wetland Mitigation Enhancement Plan for the proposed project to compensate for the permanent loss of wetland habitat The Wetland Mitigation Enhancement Plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within United States Army Corps of Engineers (Army Corps) wetland areas The mitigation measures for the Mitigated Negative Declaration and the Wetland Mitigation Enhancement Plan are included in the conditions of approval The Wetland Mitigation Enhancement and Habitat Restoration Plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures will be conducted by Sonoma County Regional Parks to compensate for the permanent and temporary impacts to wetlands and riparian habitat 1 Enhance existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional

wetlands resulting in a minimum of 417 acres of wetland enhancement 2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses 3 Direct seeding the temporary construction areas with a seed mix based on the native grasses

forbs and flowers disturbed to construct the project 4 Direct seeding from seed and mulching of temporary construction areas along the trail and at

staging areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on-site

Whereas a Mitigated Negative Declaration was prepared for the Project and noticed and

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Resolution Date 6192012 Page 3

trees and shrubs will be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement

Be It Further Resolved the Board hereby grants the requested Coastal Permit subject to

Conditions of Approval in Exhibit ldquoArdquo attached hereto approves the Project and direct the Director of Sonoma County Regional Parks to take such action as may be necessary to carry out the Project

Item 2 Proposal Statement

Proposed Site Improvements Proposed development includes 10 miles of Class 1 bikeway consisting of an 8 foot wide stabilized aggregate pathway with a 120 foot long bridge and 918 lineal feet of boardwalk crossings over designated wetlanddrainage areas The project also includes two trailhead parking areas and minor improvements to Highway 1 The following is an expanded description of the proposed project improvements

Main Trail 4220 If of 8 wide stabilized aggregate Class 1 multi-use trail with 1 wide aggregate shoulder on one side and 3 aggregate shoulder on the other for equestrian use (50640 SF) 918 lineal feet of 8 wide raised boardwalks over wetland areas (7244 SF) and a 120 long and 8 wide bridge (960 SF)

Parking Areas There are two proposed parking areas and trailheads to serve the new facilities The main parking area is accessed from Highway 1 and includes 14 permeable and 1 paved disabled stall The access road and driveway access from State Highway 1 are paved and will include a pipe gate to restrict after operating hour access The total area of this parking lot a~ce~s road and amenities is approximately 17158 square feet of which approximately 13166 square feet is paved This parking area will also provide accessible paths of travel to facilities a 6 high wood enclosure to screen a portable restroom three family picnic sites a bike rack trash cans trail signage bollards and split rail fencing to restrict vehicles access and a pull in area for busses and emergency vehicles

The second parking area is located at Keefe Avenue at the northern terminus of the proposed project This trailhead will inclode 1 paved accessible parking space with an additional 6 permeable parallel parking spaces along the shoulder This trailhead will incorporate log barriers and bollards to restrict vehicle access onto the trail Trail signage and a trash receptacle will be provided at this trailhead

Highway 1 Improvements The initial comments fromCaltrans on the proposed driveway improvements on Highway 1 requested-we-inCiudean-8-foofwicfeescape routealorfgtne eastslioulaer ortnenignway--------shydirectlymiddot across from the dmiddotriveway entry This would allow through trafficto continue north if a vehicle was stopped to yield for south bound traffic prior to turning left into the parking lot The escape route would be 8 feet wide and 300 feet long There are 50 foot tapered sections at each end for transitioning off and back onto the highway There is a utility pole on the southwest side of the entry driveway that will need to be relocated to construct the entry improvements

Scenic Highway 1 Setback The proposed parking area is set back from Coast Highway 1 by 100 feet Existing trees will screen the majority of the paved areas The only structure proposed is a small 12 by 16 by 6 foot high wood enclosure to screen a portable restroom area from view The bike and pedestrian path wooden bridge and boardwalks are set back from highway 1 over 1800feet and at least partially obscured from view by existing vegetation and topography Refer to the Initial Study (Appendix B - Visual Checklist) for a description of visual impacts of the project

Item 2 Proposal Statement

Biological Resources Impacts There are a number of biological resources that need to be protected during the implementation of this project Refer to the Initial Study document (Appendix C) for a complete discussion of biological resources impacts ami mitigation measures

Wetland Area Impacts Wetland delineation maps (Figures 1 and 2) biological resource reports (Appendix C) and a description of wetland impacts is included in the Initial Study document There will be permanent impacts to State wetlands of 139 acres We are proposing to mitigate these impacts with a 31 ratio of wetland enhancement within the project site Permanent Federal wetland impacts are less than 0003 and we are not proposing any mitigation for these impacts

Traffic Impacts A Traffic study was completed for the project August 18 2009 (See Initial Study Appendix G) The executive summary of this study identifies a less than significant traffic related project impact including the following descriptions

Access and Circulation With the removal of the existing power pole iocated along the west side of State Highway 1 across from the Caltrans maintenance facility driveway this proposed driveway location would have adequate sight distance in both directions To maintain adequate sight distance at the State Highway 1 project access driveway only low lying ground cover should be planted along the project frontage

Parking The proposed parking supply of 21 spaces is expected to adequately accommodate the projected parking demand generated by the proposed project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

bull Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method of control This method also leaves standing dead wood for wildlife habitat

bull Pile and burn This method is best used where there are many trees or woody species to be removed This is also the most labor intensive ofthe control measures

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

February 2012 18

Mitigation enhancement Site C will be considered successful if after 3 years of monitoring

bull Iceplant jubata grass and other noxious weeds have been significantly reduced or eradicated from the site (80 or more reduction in cover)

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull Monterey Pine has been eliminated from the site However dead material will be left in place as snags anq for wildlife habitat

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Interim Performance Criteria

For each year that monitoring the data is collected the data will be compared to a baseline setmiddotof data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

Trail and Staging Area Restoration Including Boardwalk Areas

Final Performance Criteria

Trail and staging area restoration sites including boardwalk areas will be considered successful if after 3 years the total vegetation cover for the restoration sites is 80 or greater absolute cover and the restored areas h~ve similar cover values and species diversity as the surrounding plant communities

The adjacent plant community to the restored area will be sampled using the same methodology described below for the restoration areas This data will be the reference site data set and will be used to compare to the restoration area

bull The average total vegetation cover is 80 or greater absolute cover

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

DATE June 19 2012 at 210 pm TO Board of Supervisors FROM Cynthia Demidovich Project Planner SUBJECT Hearing to consider a Coastal Permit for the Sonoma County Regional Parks

proposed Bodega Bay Coastal Prairie Trail Project CPH09-0007 Sonoma County Regional Parks Supervisorial District No 5

Action Requested of the Board of Supervisors The Board is requested to conduct a public hearing on the proposed Coastal Permit for the Coastal Prairie Trail At the conclusion of the hearing your Board may approve the Coastal Permit as recommended by staff Prior Actions A Mitigated Negative Declaration was previously adopted by the Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Mitigated Negative Declaration was prepared by the Sonoma County Regional Parks Department Subsequent to adopting the Mitigated Negative Declaration a Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project dated February 2012 was prepared by Jane Valerius to clarify the location of the wetland and riparian mitigation enhancement The Coastal Permit application was submitted on July 16 2009 and was deemed complete on December 19 2011 On May 15 2012 the Board of Supervisors took original jurisdiction on the proposed project as requested by the Permit and Resource Management Department (PRMD) On June 9 2012 staff sent out a Notice of Public Hearing ndash Pending Action on a Coastal Permit to surrounding neighbors and posted the Notice on and near the project site Location Zoning and Project Description Location The Coastal Prairie Trail project will be located on eight contiguous properties owned by the County of Sonoma and the State of California The parcels are located between Bay Hill Road and Keefe Avenue in Bodega Bay (a one mile route from 2255 Highway 1 to 100 Keefe Ave Bodega Bay) The base zoning for all parcels is PF (Public Facilities) and combining zones are CC (Coastal Combining) SR (Scenic Resources) and G (Geologic Hazard Area) The project area is bordered by Sonoma Coast State Park and Bodega Dunes Campground to the west and State Highway 1 to the east The Salmon Creek residential community is located on the northern boundary just beyond the proposed parking area off Keefe Avenue The southern boundary is bordered by County of Sonoma properties which is where the Bodega Bay Community Center and the Nicholas Green Memorial Bell Tower are located

June 19 2012 File No CPH09-007 Page 2 The Bodega Bay RV Park is located along the southern boundary of the Bodega Bay Community Center property Approximately 300-feet of shoulder along the east side of State Highway 1 will be widened for the proposed State Highway 1 improvement near the south driveway that serves the trailhead The area of the shoulder widening is generally within property owned by Caltrans and is bordered by private residential property The project area and vicinity includes a vast array of biological resources including upland and wetland plant communities that provide habitat to many wildlife species some of which are sensitive species The project area is a mosaic of habitats including coastal terrace prairie northern coastal scrub and wetlands typical of the Sonoma County coastal environment An unnamed stream traverses one of the State Parks properties and is surrounded by dense riparian vegetation The project area also includes stands of Monterey cypress eucalyptus and Monterey pine A bridge is intended to cross a USGS mapped stream channel located on the project site This stream is unnamed It originates on the east side of Highway 1 between two saddles on the northern slope of Mount Roscoe and flows in an east-west direction parallel to the entrance road to the Bodega Dunes State Park within State Parks property Within the project area the stream empties into a large palustrine emergent wetland and is surrounded by the Arroyo Willow plant community Ultimately the stream drains further into two basins within coastal dune habitat on State Parks property Trail Improvements The proposed project is a request for a Coastal Permit to construct a trail known as the Coastal Prairie Trail The trail is designed as a Class 1 bike path and will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian uses The trail will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rock aggregated shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side the three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trail will consist of approximately 918 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge over the unnamed tributary Bridge Improvements A pre-fabricated wooden-deck bridge will be installed over the unnamed tributary that flows through one of the State Parks properties The bridge will be single-span and 120-feet in length and 8-feet in width The bridge will include boardwalk approaches each 32-foot long and 8-foot wide on both ends of the bridge to complete the span over the tributary and 12-foot by 10-foot concrete landing pads on both ends of the boardwalk sections Parking Improvements The trailhead will be located approximately half-way along the trail approximately 010 mile south of State Parkrsquos Bodega Dunes Campground entrance road off State Highway 1 The trailhead will include a parking area accessed from a paved entrance a screened portable restroom picnic tables bicycle rack trash cans and other amenities The trailhead parking area will accommodate approximately 15 passenger vehicles including one van accessible disabled parking space in compliance with ADA requirements The trailhead parking area will include access for school and public transit busses as well as emergency access vehicles Additional parking for seven vehicles including one ADA-compliant parking space will be provided at the northern terminus of the Coastal Prairie Trail at Keefe

June 19 2012 File No CPH09-007 Page 3 Avenue A wildlife-friendly vehicle barrier consisting of logs and bollards will be placed around the parking areas so that vehicles cannot drive onto the trail itself State Highway 1 Improvements A 300-foot section of shoulder along the east side of Highway 1 will be widened to provide an 8-foot paved width across from the access driveway to the trailhead parking area The paved shoulder will include 50-foot long tapered ends on both sides The purpose is to provide an area to pass vehicles making the left turn into the trailhead parking area This improvement will occur on both sides of the Caltrans maintenance facility driveway on an existing Caltrans easement The project will also include installation of two culverts on the south side of the Bodega Dunes Campground entry road interpretive and operational signage along the trail and relocation of one PGampE utility pole along State Highway 1 Purpose and Need for the Project Project Purpose The purpose of the proposed project is to develop a section of Class I bicycle path along State Highway 1 to provide a safe travel way separate from the State highway The Class I bicycle path will be multi-use for bicycle pedestrian and equestrian use Currently the only path for non-motorized use along this section of State Highway 1 is a very narrow section of paved shoulder immediately adjacent to the vehicle travel lane Development of the Coastal Prairie Trail is expected to encourage alternatives to motorized travel between existing residential recreational and commercial areas in Bodega Bay and reduce traffic congestion Project Need The development of a continuous trail through the unincorporated Town of Bodega Bay and the immediate surrounding area has long been a community goal Topographic and land use constraints have presented numerous challenges to the development of such a trail Long stretches of Highway 1 cut through the center of town These stretches have little to no road shoulder because of existing right-of-way vegetation and topography Numerous residential structures have been built alongside Highway 1 creating sight distance problems around curves and leaving little room to walk bicycle ride horses or use any form of alternative transportation The existing condition forces non-motorized travelers onto the narrow shoulders along Highway 1

DISCUSSION OF ISSUES

Issue 1 General Plan Consistency The General Plan land use designation for the subject parcel is PQP (Public and Quasi Public) General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs and owned or operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

June 19 2012 File No CPH09-007 Page 4 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks and the new trail will benefit and be used by the general public General Plan Policy OSRC-17d of the Open Space and Resource Conservation defines the ldquoSonoma Coast Trailrdquo as extending from Black Point to the Estero Americano and finds the trail consistent with the California State Coastal Plan Policy 145 that calls for the establishment of a statewide coastal trail system This General Plan Policy also states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and the Coastal Prairie Trail is a segment of the Sonoma Coast Trail General Plan Policy CT-3v of the Circulation and Transit Element states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public General Plan Policy CT-3q of the Circulation and Transit Element states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeways Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail As conditioned the proposed project is consistent with the goals objectives and policies of the General Plan Issue 2 Local Coastal Plan Consistency The Local Coastal Plan land use designation for the subject site is Institutional and Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located on two public parks and the new trail will benefit and be used by the general public The proposed project is consistent with the Coastal Land Use designation of Institutional The Recreation Resources section of the Local Coastal Plan per section V-3 requires the following development criteria for coastal access trails

Among the facilities needed for access ways and shoreline destinations are safe trails restrooms parking areas trash receptacles and signs Necessary facilities at a particular site will depend upon expected use and the availability of facilities nearby

The Coastal Prairie Trail is designed as a Class 1 bike path and will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian uses and provides coastal access to the public Restroom facilities and trash receptacles will be located at the south trailhead Adequate parking areas and trail signs will be located at the south and north trailheads The proposed project is consistent with the Recreation Resources section of the Local Coastal Plan Issue 3 Coastal Zoning Ordinance Consistency The Coastal Zoning designation for the subject parcels is PF (Public Facilities) CC (Coastal Combining District) G (Geologic Hazard) SR (Scenic Resource Combining District) Section 26C-182(a) of the

June 19 2012 File No CPH09-007 Page 5 Public Facilities Zoning district allows any facility owned and operated by a city or the county as an allowed use without a Use Permit The proposed project will not have an effect on a Scenic Resource Combining District as the facilities will be screened by existing vegetation and natural terrain The materials used will blend in with the native surroundings as the aggregate used for the trail surface will be tinted an earth tone color and wood will be used for the boardwalks and bridge The trail will be constructed at grade following natural contours of the land The trailhead parking area accessed from Highway 1 will be well screened by existing vegetation Issue 4 Environmentally Sensitive Habitat Areas Wetlands The following policies from the Environmental Resources section of the Sonoma County Local Coastal Plan apply to the proposed project

Section III-1of the Local Coastal Plan

30233 (a) The diking filling or dredging of open coastal waters wetlands estuaries and lakes shall be permitted in accordance with other applicable provisions of this division where there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects and shall be limited to the following

(7) Nature study aquaculture or similar resource-dependent activities

(c) In addition to the other provisions of this section diking filling or dredging in existing estuaries and wetlands shall maintain or enhance the functional capacity of the wetland or estuary Any alteration of coastal wetlands identified by the Department of Fish and Game including but not limited to the 19 coastal wetlands identified in its report entitled Acquisition Priorities for the Coastal Wetlands of California shall be limited to very minor incidental public facilities restorative measures nature study commercial fishing facilities in Bodega Bay and development in already developed parts of south San Diego Bay if otherwise in accordance with this division

This Section of the Coastal Plan allows filling of wetlands when there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects provided the use is nature study aquaculture or similar resource-dependent activities In addition this Section limits the fill of a wetland to very minor incidental public facilities The proposed project has been designed to avoid and minimize damage to wetlands Permanent impacts to the wetlands would be from the boardwalk footings and regular trail sections To offset the loss of the wetland Regional Parks is proposing to enhance the on-site existing wetland at a 31 ratio (see discussion listed below Issue 5) The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access In addition the Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system

June 19 2012 File No CPH09-007 Page 6

Section III-2 of the Local Coastal Plan

30240 (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat values and only uses dependent on such resources shall be allowed within such areas

(b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation areas shall be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of such habitat areas

Wetlands are considered environmentally sensitive habitats in the Local Coastal Plan The trail has been designed to minimize impacts to existing wetlands as the impacts will occur to low quality wetlands The applicant is proposing to enhance on-site wetland habitat values at a 31 which is equal to approximately 417 acres of enhancement (see additional discussion listed below Issue 5) In addition a 185 acre of wetland enhancement will also take place on-site Section III-13 of the Local Coastal Plan

(24) Prohibit the removal of vegetation from wetlands unless it is shown to be essential to the habitat viability

(25) Prohibit construction of agricultural commercial industrial and residential structures within 100 feet of wetlands

(26) Between 100 and 300 feet of wetlands prohibit construction of agricultural commercial industrial and residential structures unless an environment assessment finds the wetland would not be affected by such construction

As previously stated the on-site wetland habitat will be enhanced at a 31 ratio and the proposed use is not an agricultural commercial industrial or residential the use is considered a recreational use The trail is a resource-dependent use as the nature trail provides coastal access to the public Riparian Habitat

Section III-12 Local Coastal Plan

(9) Prohibit construction of permanent structures within riparian areas as defined or 100 feet from the lowest line of riparian vegetation whichever is greater except development dependent on there sources in the riparian habitat including public recreation facilities related to the resource Any development shall be allowed only if it can be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of the riparian habitat The riparian area or 100 foot wide buffer zone should generally be maintained in a natural undisturbed state Trails and access may be permitted if studies determine no long-term adverse impacts would result from their construction maintenance and public use Trails should be made of porous materials

This Section from the Local Coastal Plan allows development to encroach within the 100-foot riparian setback provided the project is sited and designed to prevent impacts which would significantly degrade the riparian habitat Trails and access is permitted if studies determine there is no long-term adverse impacts due to construction maintenance and public use

June 19 2012 File No CPH09-007 Page 7 The proposed project includes a bridge with a wooden-deck to be installed over an unnamed tributary that flows through one of the State Parks properties (north of Bodega Dunes State Park) The 120-foot long bridge will minimize impacts to the surrounding willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only due to the removal of approximately 20 square feet of willowswoodlandriparian plants The Wetland Mitigation Enhancement and Habitat Restoration Plan requires native trees and shrubs be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement Issue 5 Impacts on Wetlands The proposed project will create temporary and permanent impacts to wetland habitat Temporary impacts will be the result of construction activities The wetlands under federal jurisdiction and those are state jurisdiction are located on the proposed trail and adjacent east and west side of the trail In the federal wetlands permanent impacts would be from the boardwalk footings In the state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections The boardwalks themselves will not result in permanent impacts to either federal or state wetlands because they will either be avoided or minimized as a result of the placement of boardwalks Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks are proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only State Wetlands Wetland areas under California Coastal Commission (CCC) jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock-aggregate shoulders Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub This area was likely coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhancement is to eliminate the invading coyote bush iceplant and non-native grasses and increase the native species cover and re-establish the coastal prairie community type The purpose and goal of

June 19 2012 File No CPH09-007 Page 8 enhancing the existing coastal scrub community by converting it to a native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition The proposed project will create the following temporary and permanent impacts to wetlands located on the project site Temporary Impacts Permanent Impacts Federal Wetlands 039 acres temporary impacts +-0003 acres permanent impacts (17080 square feet) (1410 square feet) State Wetlands 329 acres temporary impacts 139 acres permanent impacts (143314 square feet) (60436 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project (prepared by Jane Valerius dated February 2012) provides a Wetland Mitigation Enhancement Plan for the proposed project to compensate for the permanent loss of wetland habitat The Wetland Mitigation Enhancement Plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within United States Army Corps of Engineers (Army Corps) wetland areas The mitigation measures for the Mitigated Negative Declaration and the Wetland Mitigation Enhancement Plan are included in the conditions of approval The Wetland Mitigation Enhancement and Habitat Restoration Plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures will be conducted by Sonoma County Regional Parks to compensate for the permanent and temporary impacts to wetlands and riparian habitat 1 Enhance existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional

wetlands resulting in a minimum of 417 acres of wetland enhancement 2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses 3 Direct seeding the temporary construction areas with a seed mix based on the native grasses

forbs and flowers disturbed to construct the project 4 Direct seeding from seed and mulching of temporary construction areas along the trail and at

staging areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on-site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting

native trees and shrubs 6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct

seeding of native coastal prairie species south of the Bodega Dunes Park entrance road 7 Monitoring and following performance criteria for wetland enhancement for a minimum of three

years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

bull Monitor the re-vegetationplant community restoration for a three year period bull Replant as needed to achieve a 75 percent total survivability

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

June 19 2012 File No CPH09-007 Page 2 The Bodega Bay RV Park is located along the southern boundary of the Bodega Bay Community Center property Approximately 300-feet of shoulder along the east side of State Highway 1 will be widened for the proposed State Highway 1 improvement near the south driveway that serves the trailhead The area of the shoulder widening is generally within property owned by Caltrans and is bordered by private residential property The project area and vicinity includes a vast array of biological resources including upland and wetland plant communities that provide habitat to many wildlife species some of which are sensitive species The project area is a mosaic of habitats including coastal terrace prairie northern coastal scrub and wetlands typical of the Sonoma County coastal environment An unnamed stream traverses one of the State Parks properties and is surrounded by dense riparian vegetation The project area also includes stands of Monterey cypress eucalyptus and Monterey pine A bridge is intended to cross a USGS mapped stream channel located on the project site This stream is unnamed It originates on the east side of Highway 1 between two saddles on the northern slope of Mount Roscoe and flows in an east-west direction parallel to the entrance road to the Bodega Dunes State Park within State Parks property Within the project area the stream empties into a large palustrine emergent wetland and is surrounded by the Arroyo Willow plant community Ultimately the stream drains further into two basins within coastal dune habitat on State Parks property Trail Improvements The proposed project is a request for a Coastal Permit to construct a trail known as the Coastal Prairie Trail The trail is designed as a Class 1 bike path and will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian uses The trail will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rock aggregated shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side the three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trail will consist of approximately 918 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge over the unnamed tributary Bridge Improvements A pre-fabricated wooden-deck bridge will be installed over the unnamed tributary that flows through one of the State Parks properties The bridge will be single-span and 120-feet in length and 8-feet in width The bridge will include boardwalk approaches each 32-foot long and 8-foot wide on both ends of the bridge to complete the span over the tributary and 12-foot by 10-foot concrete landing pads on both ends of the boardwalk sections Parking Improvements The trailhead will be located approximately half-way along the trail approximately 010 mile south of State Parkrsquos Bodega Dunes Campground entrance road off State Highway 1 The trailhead will include a parking area accessed from a paved entrance a screened portable restroom picnic tables bicycle rack trash cans and other amenities The trailhead parking area will accommodate approximately 15 passenger vehicles including one van accessible disabled parking space in compliance with ADA requirements The trailhead parking area will include access for school and public transit busses as well as emergency access vehicles Additional parking for seven vehicles including one ADA-compliant parking space will be provided at the northern terminus of the Coastal Prairie Trail at Keefe

June 19 2012 File No CPH09-007 Page 3 Avenue A wildlife-friendly vehicle barrier consisting of logs and bollards will be placed around the parking areas so that vehicles cannot drive onto the trail itself State Highway 1 Improvements A 300-foot section of shoulder along the east side of Highway 1 will be widened to provide an 8-foot paved width across from the access driveway to the trailhead parking area The paved shoulder will include 50-foot long tapered ends on both sides The purpose is to provide an area to pass vehicles making the left turn into the trailhead parking area This improvement will occur on both sides of the Caltrans maintenance facility driveway on an existing Caltrans easement The project will also include installation of two culverts on the south side of the Bodega Dunes Campground entry road interpretive and operational signage along the trail and relocation of one PGampE utility pole along State Highway 1 Purpose and Need for the Project Project Purpose The purpose of the proposed project is to develop a section of Class I bicycle path along State Highway 1 to provide a safe travel way separate from the State highway The Class I bicycle path will be multi-use for bicycle pedestrian and equestrian use Currently the only path for non-motorized use along this section of State Highway 1 is a very narrow section of paved shoulder immediately adjacent to the vehicle travel lane Development of the Coastal Prairie Trail is expected to encourage alternatives to motorized travel between existing residential recreational and commercial areas in Bodega Bay and reduce traffic congestion Project Need The development of a continuous trail through the unincorporated Town of Bodega Bay and the immediate surrounding area has long been a community goal Topographic and land use constraints have presented numerous challenges to the development of such a trail Long stretches of Highway 1 cut through the center of town These stretches have little to no road shoulder because of existing right-of-way vegetation and topography Numerous residential structures have been built alongside Highway 1 creating sight distance problems around curves and leaving little room to walk bicycle ride horses or use any form of alternative transportation The existing condition forces non-motorized travelers onto the narrow shoulders along Highway 1

DISCUSSION OF ISSUES

Issue 1 General Plan Consistency The General Plan land use designation for the subject parcel is PQP (Public and Quasi Public) General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs and owned or operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

June 19 2012 File No CPH09-007 Page 4 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks and the new trail will benefit and be used by the general public General Plan Policy OSRC-17d of the Open Space and Resource Conservation defines the ldquoSonoma Coast Trailrdquo as extending from Black Point to the Estero Americano and finds the trail consistent with the California State Coastal Plan Policy 145 that calls for the establishment of a statewide coastal trail system This General Plan Policy also states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and the Coastal Prairie Trail is a segment of the Sonoma Coast Trail General Plan Policy CT-3v of the Circulation and Transit Element states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public General Plan Policy CT-3q of the Circulation and Transit Element states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeways Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail As conditioned the proposed project is consistent with the goals objectives and policies of the General Plan Issue 2 Local Coastal Plan Consistency The Local Coastal Plan land use designation for the subject site is Institutional and Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located on two public parks and the new trail will benefit and be used by the general public The proposed project is consistent with the Coastal Land Use designation of Institutional The Recreation Resources section of the Local Coastal Plan per section V-3 requires the following development criteria for coastal access trails

Among the facilities needed for access ways and shoreline destinations are safe trails restrooms parking areas trash receptacles and signs Necessary facilities at a particular site will depend upon expected use and the availability of facilities nearby

The Coastal Prairie Trail is designed as a Class 1 bike path and will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian uses and provides coastal access to the public Restroom facilities and trash receptacles will be located at the south trailhead Adequate parking areas and trail signs will be located at the south and north trailheads The proposed project is consistent with the Recreation Resources section of the Local Coastal Plan Issue 3 Coastal Zoning Ordinance Consistency The Coastal Zoning designation for the subject parcels is PF (Public Facilities) CC (Coastal Combining District) G (Geologic Hazard) SR (Scenic Resource Combining District) Section 26C-182(a) of the

June 19 2012 File No CPH09-007 Page 5 Public Facilities Zoning district allows any facility owned and operated by a city or the county as an allowed use without a Use Permit The proposed project will not have an effect on a Scenic Resource Combining District as the facilities will be screened by existing vegetation and natural terrain The materials used will blend in with the native surroundings as the aggregate used for the trail surface will be tinted an earth tone color and wood will be used for the boardwalks and bridge The trail will be constructed at grade following natural contours of the land The trailhead parking area accessed from Highway 1 will be well screened by existing vegetation Issue 4 Environmentally Sensitive Habitat Areas Wetlands The following policies from the Environmental Resources section of the Sonoma County Local Coastal Plan apply to the proposed project

Section III-1of the Local Coastal Plan

30233 (a) The diking filling or dredging of open coastal waters wetlands estuaries and lakes shall be permitted in accordance with other applicable provisions of this division where there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects and shall be limited to the following

(7) Nature study aquaculture or similar resource-dependent activities

(c) In addition to the other provisions of this section diking filling or dredging in existing estuaries and wetlands shall maintain or enhance the functional capacity of the wetland or estuary Any alteration of coastal wetlands identified by the Department of Fish and Game including but not limited to the 19 coastal wetlands identified in its report entitled Acquisition Priorities for the Coastal Wetlands of California shall be limited to very minor incidental public facilities restorative measures nature study commercial fishing facilities in Bodega Bay and development in already developed parts of south San Diego Bay if otherwise in accordance with this division

This Section of the Coastal Plan allows filling of wetlands when there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects provided the use is nature study aquaculture or similar resource-dependent activities In addition this Section limits the fill of a wetland to very minor incidental public facilities The proposed project has been designed to avoid and minimize damage to wetlands Permanent impacts to the wetlands would be from the boardwalk footings and regular trail sections To offset the loss of the wetland Regional Parks is proposing to enhance the on-site existing wetland at a 31 ratio (see discussion listed below Issue 5) The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access In addition the Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system

June 19 2012 File No CPH09-007 Page 6

Section III-2 of the Local Coastal Plan

30240 (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat values and only uses dependent on such resources shall be allowed within such areas

(b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation areas shall be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of such habitat areas

Wetlands are considered environmentally sensitive habitats in the Local Coastal Plan The trail has been designed to minimize impacts to existing wetlands as the impacts will occur to low quality wetlands The applicant is proposing to enhance on-site wetland habitat values at a 31 which is equal to approximately 417 acres of enhancement (see additional discussion listed below Issue 5) In addition a 185 acre of wetland enhancement will also take place on-site Section III-13 of the Local Coastal Plan

(24) Prohibit the removal of vegetation from wetlands unless it is shown to be essential to the habitat viability

(25) Prohibit construction of agricultural commercial industrial and residential structures within 100 feet of wetlands

(26) Between 100 and 300 feet of wetlands prohibit construction of agricultural commercial industrial and residential structures unless an environment assessment finds the wetland would not be affected by such construction

As previously stated the on-site wetland habitat will be enhanced at a 31 ratio and the proposed use is not an agricultural commercial industrial or residential the use is considered a recreational use The trail is a resource-dependent use as the nature trail provides coastal access to the public Riparian Habitat

Section III-12 Local Coastal Plan

(9) Prohibit construction of permanent structures within riparian areas as defined or 100 feet from the lowest line of riparian vegetation whichever is greater except development dependent on there sources in the riparian habitat including public recreation facilities related to the resource Any development shall be allowed only if it can be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of the riparian habitat The riparian area or 100 foot wide buffer zone should generally be maintained in a natural undisturbed state Trails and access may be permitted if studies determine no long-term adverse impacts would result from their construction maintenance and public use Trails should be made of porous materials

This Section from the Local Coastal Plan allows development to encroach within the 100-foot riparian setback provided the project is sited and designed to prevent impacts which would significantly degrade the riparian habitat Trails and access is permitted if studies determine there is no long-term adverse impacts due to construction maintenance and public use

June 19 2012 File No CPH09-007 Page 7 The proposed project includes a bridge with a wooden-deck to be installed over an unnamed tributary that flows through one of the State Parks properties (north of Bodega Dunes State Park) The 120-foot long bridge will minimize impacts to the surrounding willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only due to the removal of approximately 20 square feet of willowswoodlandriparian plants The Wetland Mitigation Enhancement and Habitat Restoration Plan requires native trees and shrubs be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement Issue 5 Impacts on Wetlands The proposed project will create temporary and permanent impacts to wetland habitat Temporary impacts will be the result of construction activities The wetlands under federal jurisdiction and those are state jurisdiction are located on the proposed trail and adjacent east and west side of the trail In the federal wetlands permanent impacts would be from the boardwalk footings In the state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections The boardwalks themselves will not result in permanent impacts to either federal or state wetlands because they will either be avoided or minimized as a result of the placement of boardwalks Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks are proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only State Wetlands Wetland areas under California Coastal Commission (CCC) jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock-aggregate shoulders Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub This area was likely coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhancement is to eliminate the invading coyote bush iceplant and non-native grasses and increase the native species cover and re-establish the coastal prairie community type The purpose and goal of

June 19 2012 File No CPH09-007 Page 8 enhancing the existing coastal scrub community by converting it to a native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition The proposed project will create the following temporary and permanent impacts to wetlands located on the project site Temporary Impacts Permanent Impacts Federal Wetlands 039 acres temporary impacts +-0003 acres permanent impacts (17080 square feet) (1410 square feet) State Wetlands 329 acres temporary impacts 139 acres permanent impacts (143314 square feet) (60436 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project (prepared by Jane Valerius dated February 2012) provides a Wetland Mitigation Enhancement Plan for the proposed project to compensate for the permanent loss of wetland habitat The Wetland Mitigation Enhancement Plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within United States Army Corps of Engineers (Army Corps) wetland areas The mitigation measures for the Mitigated Negative Declaration and the Wetland Mitigation Enhancement Plan are included in the conditions of approval The Wetland Mitigation Enhancement and Habitat Restoration Plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures will be conducted by Sonoma County Regional Parks to compensate for the permanent and temporary impacts to wetlands and riparian habitat 1 Enhance existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional

wetlands resulting in a minimum of 417 acres of wetland enhancement 2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses 3 Direct seeding the temporary construction areas with a seed mix based on the native grasses

forbs and flowers disturbed to construct the project 4 Direct seeding from seed and mulching of temporary construction areas along the trail and at

staging areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on-site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting

native trees and shrubs 6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct

seeding of native coastal prairie species south of the Bodega Dunes Park entrance road 7 Monitoring and following performance criteria for wetland enhancement for a minimum of three

years after all seeding planting and weed control activities have been completed

June 19 2012 File No CPH09-007 Page 9

In addition to the 417 acre of wetland enhancement listed above another 185 acre of wetland enhancement will also take place on-site The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Army Corps and Regional Water Quality Control Board (RWQCB) by January 31st of each year The first year annual report will be submitted after the first growing season after planting The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites Issue 6 Impacts on Riparian Habitat The proposed project will create temporary and permanent impacts to riparian habitat Temporary impacts are associated with construction activities and the areas will be restored to their pre-construction condition after construction activities are complete Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community at this location The proposed project will create the following temporary and permanent impacts to riparian habitat located on the project site Temporary Impacts Permanent Impacts Arroyo Willow temporary impacts 0022 acres permanent impacts 00003 acres Riparian Woodland (962 square feet) (126 square feet) Arroyo Willow temporary impacts 0015 acres permanent impacts 00002 acres Sedge Woodland (660 square feet) (70 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The previously mentioned Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project also provides a riparian mitigation enhancement plan for the proposed project to compensate for the permanent loss of riparian habitat The plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures that are included in the condition of approval 1 Plant native trees and shrubs at a 31 ratio based on trees removed from the riparian areas that

have a breast-height diameter of 6-inches or greater resulting in a minimum of 55 acres of riparian enhancement In the case of removal of non-native species a suitable native species will be selected for replanting

June 19 2012 File No CPH09-007 Page 10 2 Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the

native grasses forbs and flowers disturbed to construct the project 3 Monitor the re-vegetationplant community restoration for a three year period 4 Replant as needed to achieve a 75 percent total survivability

The mitigation sites will be monitored for a minimum of three years and an annual report describing the monitoring efforts will be submitted to the CCC the Army Corps and Regional Water Quality Control Board (RWQCB) by January 31st of each year The first year annual report will be submitted after the first growing season after planting Mitigation Measures require the annual reports to include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species of plants replaced an overview of the revegetation effort and the method used to assess these parameters shall also be included Photos from designated photo locations shall also be included in the annual reports Issue 7 Environmental Review As indicated previously a Mitigated Negative Declaration was previously adopted and approved by the Sonoma County Board of Supervisors on June 21 2011 and the Board found the proposed project will not have a significant effect on the environment provided that mitigation measures are included No additional environmental review is required under Section 15168(c)(2) of CEQA as no new effects could occur and no new mitigation measures are required as the project is within the scope of the project covered by the previously adopted and approved Mitigated Negative Declaration pursuant to Section 15162 of CEQA List of Attachments Draft Board of Supervisors Resolution EXHIBIT A Draft Conditions of Approval EXHIBIT B Proposal Statement EXHIBIT C Vicinity Maps EXHIBIT D Site Plan EXHIBIT E Assessors Parcels EXHIBIT F General Plan Map EXHIBIT G Zoning Map EXHIBIT H Coastal Land Use Map EXHIBIT I Wetland Mitigation Enhancement and Habitat Plan dated February 2012 EXHIBIT J Southern Biological Study Area Map EXHIBIT K Northern Biological Study Area Map EXHIBIT L Southern Enhancement and Restoration Map EXHIBIT M Northern Enhancement and Restoration Map __________________________________________________________________________________ Separate Attachment for the Board of Supervisors and On File with the Clerk Previously Adopted Mitigated Negative Declaration June 21 2011

the Bodega Bay Coastal Prairie Trail Project located along a one mile route extending from 2255 Highway 1 to 100 Keefe Ave Bodega Bay APNs 100-220-008 100-230-001 100-230-042 100-020-019 101-020-042 101-020-043 101-020-044 and 101-020-045 Zoning PF (Public Facilities) CC (Coastal Combining) SR (Scenic Resources) and G (Geologic Hazard Area) Supervisorial District No 5 (the ldquoProjectrdquo) and

Whereas a Mitigated Negative Declaration was prepared for the Project and noticed and

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Resolution Date 6192012 Page 3

trees and shrubs will be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement

Be It Further Resolved the Board hereby grants the requested Coastal Permit subject to

Conditions of Approval in Exhibit ldquoArdquo attached hereto approves the Project and direct the Director of Sonoma County Regional Parks to take such action as may be necessary to carry out the Project

Be It Further Resolved that the Board of Supervisors designates the Clerk of the Board as the custodian of the documents and other material which constitute the record of proceedings upon which the decision herein is based These documents may be found at the office of the Clerk of the Board 575 Administration Drive Room 100-A Santa Rosa California 95403

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

bull Monitor the re-vegetationplant community restoration for a three year period bull Replant as needed to achieve a 75 percent total survivability

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

The following provides the methods and treatments to be applied to the enhancement and restoration sites for mitigation of both permanent and temporary impacts from the proposed project Table 1 provides a list of plant species-that will be used for seeding and planting for wetland mitigation enhancement and grassland habitat restoration The species on the list are based on the plant surveys conducted for the project and all these species occur within the trail alignment

Figures 1 and 2 show the location of the mitigation sites and the associated existing plant community types along the trail Figures 3 and 4 show the plant species recommended for seeding All figures are provided as attachments at the end of this report Photographs of Sites A Band C are provided in Appendix A

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

A minimum of 20 randomly placed sample plots will be selected within each vegetation community type along the trail in both the restored area and adjacent plant community or reference area The restqration sites will be considered successful if after 3 years

bull The average total vegetation cover is 80 or greater absolute cover

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss

4 little or no new growth apparent 5 healthy vigorous new growth

The survival rate for container stock planteq will be 75 at the end of 3 years ofmonitoring

Photos will be taken during the annual monitoring session at photo points and will be indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Interim Peiformance Criteria -Year One Percent absolute total vegetation cover is 50 or greater Year Two Percent absolute total vegetation cover is 70 or greater Year Three Percent absolute total vegetation cover is 80 or greater

Vegetation cover and species diversity will be compared to the adjacent plant community Each year there should be a trend that demonstrates that the restored (seeded and planted areas) have the same or similar plant species that reflect the surrounding plant community type

A minimum of 20 randomly placed sample plots will be selected within each vegetation community type along the trail The diversity of species will be the same or greater than the surrounding plant community For Corps wetland areas (boardwalk wetlands) the cover values will be based on cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Container plants if any are installed will have a 90 survival rate for the first year and 80 for the second year with 75 for the third year

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 eviderice of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or no new growth apparent 5 healthy vigorous new growth

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

June 19 2012 File No CPH09-007 Page 3 Avenue A wildlife-friendly vehicle barrier consisting of logs and bollards will be placed around the parking areas so that vehicles cannot drive onto the trail itself State Highway 1 Improvements A 300-foot section of shoulder along the east side of Highway 1 will be widened to provide an 8-foot paved width across from the access driveway to the trailhead parking area The paved shoulder will include 50-foot long tapered ends on both sides The purpose is to provide an area to pass vehicles making the left turn into the trailhead parking area This improvement will occur on both sides of the Caltrans maintenance facility driveway on an existing Caltrans easement The project will also include installation of two culverts on the south side of the Bodega Dunes Campground entry road interpretive and operational signage along the trail and relocation of one PGampE utility pole along State Highway 1 Purpose and Need for the Project Project Purpose The purpose of the proposed project is to develop a section of Class I bicycle path along State Highway 1 to provide a safe travel way separate from the State highway The Class I bicycle path will be multi-use for bicycle pedestrian and equestrian use Currently the only path for non-motorized use along this section of State Highway 1 is a very narrow section of paved shoulder immediately adjacent to the vehicle travel lane Development of the Coastal Prairie Trail is expected to encourage alternatives to motorized travel between existing residential recreational and commercial areas in Bodega Bay and reduce traffic congestion Project Need The development of a continuous trail through the unincorporated Town of Bodega Bay and the immediate surrounding area has long been a community goal Topographic and land use constraints have presented numerous challenges to the development of such a trail Long stretches of Highway 1 cut through the center of town These stretches have little to no road shoulder because of existing right-of-way vegetation and topography Numerous residential structures have been built alongside Highway 1 creating sight distance problems around curves and leaving little room to walk bicycle ride horses or use any form of alternative transportation The existing condition forces non-motorized travelers onto the narrow shoulders along Highway 1

DISCUSSION OF ISSUES

Issue 1 General Plan Consistency The General Plan land use designation for the subject parcel is PQP (Public and Quasi Public) General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs and owned or operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

June 19 2012 File No CPH09-007 Page 4 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks and the new trail will benefit and be used by the general public General Plan Policy OSRC-17d of the Open Space and Resource Conservation defines the ldquoSonoma Coast Trailrdquo as extending from Black Point to the Estero Americano and finds the trail consistent with the California State Coastal Plan Policy 145 that calls for the establishment of a statewide coastal trail system This General Plan Policy also states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and the Coastal Prairie Trail is a segment of the Sonoma Coast Trail General Plan Policy CT-3v of the Circulation and Transit Element states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public General Plan Policy CT-3q of the Circulation and Transit Element states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeways Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail As conditioned the proposed project is consistent with the goals objectives and policies of the General Plan Issue 2 Local Coastal Plan Consistency The Local Coastal Plan land use designation for the subject site is Institutional and Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located on two public parks and the new trail will benefit and be used by the general public The proposed project is consistent with the Coastal Land Use designation of Institutional The Recreation Resources section of the Local Coastal Plan per section V-3 requires the following development criteria for coastal access trails

Among the facilities needed for access ways and shoreline destinations are safe trails restrooms parking areas trash receptacles and signs Necessary facilities at a particular site will depend upon expected use and the availability of facilities nearby

The Coastal Prairie Trail is designed as a Class 1 bike path and will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian uses and provides coastal access to the public Restroom facilities and trash receptacles will be located at the south trailhead Adequate parking areas and trail signs will be located at the south and north trailheads The proposed project is consistent with the Recreation Resources section of the Local Coastal Plan Issue 3 Coastal Zoning Ordinance Consistency The Coastal Zoning designation for the subject parcels is PF (Public Facilities) CC (Coastal Combining District) G (Geologic Hazard) SR (Scenic Resource Combining District) Section 26C-182(a) of the

June 19 2012 File No CPH09-007 Page 5 Public Facilities Zoning district allows any facility owned and operated by a city or the county as an allowed use without a Use Permit The proposed project will not have an effect on a Scenic Resource Combining District as the facilities will be screened by existing vegetation and natural terrain The materials used will blend in with the native surroundings as the aggregate used for the trail surface will be tinted an earth tone color and wood will be used for the boardwalks and bridge The trail will be constructed at grade following natural contours of the land The trailhead parking area accessed from Highway 1 will be well screened by existing vegetation Issue 4 Environmentally Sensitive Habitat Areas Wetlands The following policies from the Environmental Resources section of the Sonoma County Local Coastal Plan apply to the proposed project

Section III-1of the Local Coastal Plan

30233 (a) The diking filling or dredging of open coastal waters wetlands estuaries and lakes shall be permitted in accordance with other applicable provisions of this division where there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects and shall be limited to the following

(7) Nature study aquaculture or similar resource-dependent activities

(c) In addition to the other provisions of this section diking filling or dredging in existing estuaries and wetlands shall maintain or enhance the functional capacity of the wetland or estuary Any alteration of coastal wetlands identified by the Department of Fish and Game including but not limited to the 19 coastal wetlands identified in its report entitled Acquisition Priorities for the Coastal Wetlands of California shall be limited to very minor incidental public facilities restorative measures nature study commercial fishing facilities in Bodega Bay and development in already developed parts of south San Diego Bay if otherwise in accordance with this division

This Section of the Coastal Plan allows filling of wetlands when there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects provided the use is nature study aquaculture or similar resource-dependent activities In addition this Section limits the fill of a wetland to very minor incidental public facilities The proposed project has been designed to avoid and minimize damage to wetlands Permanent impacts to the wetlands would be from the boardwalk footings and regular trail sections To offset the loss of the wetland Regional Parks is proposing to enhance the on-site existing wetland at a 31 ratio (see discussion listed below Issue 5) The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access In addition the Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system

June 19 2012 File No CPH09-007 Page 6

Section III-2 of the Local Coastal Plan

30240 (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat values and only uses dependent on such resources shall be allowed within such areas

(b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation areas shall be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of such habitat areas

Wetlands are considered environmentally sensitive habitats in the Local Coastal Plan The trail has been designed to minimize impacts to existing wetlands as the impacts will occur to low quality wetlands The applicant is proposing to enhance on-site wetland habitat values at a 31 which is equal to approximately 417 acres of enhancement (see additional discussion listed below Issue 5) In addition a 185 acre of wetland enhancement will also take place on-site Section III-13 of the Local Coastal Plan

(24) Prohibit the removal of vegetation from wetlands unless it is shown to be essential to the habitat viability

(25) Prohibit construction of agricultural commercial industrial and residential structures within 100 feet of wetlands

(26) Between 100 and 300 feet of wetlands prohibit construction of agricultural commercial industrial and residential structures unless an environment assessment finds the wetland would not be affected by such construction

As previously stated the on-site wetland habitat will be enhanced at a 31 ratio and the proposed use is not an agricultural commercial industrial or residential the use is considered a recreational use The trail is a resource-dependent use as the nature trail provides coastal access to the public Riparian Habitat

Section III-12 Local Coastal Plan

(9) Prohibit construction of permanent structures within riparian areas as defined or 100 feet from the lowest line of riparian vegetation whichever is greater except development dependent on there sources in the riparian habitat including public recreation facilities related to the resource Any development shall be allowed only if it can be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of the riparian habitat The riparian area or 100 foot wide buffer zone should generally be maintained in a natural undisturbed state Trails and access may be permitted if studies determine no long-term adverse impacts would result from their construction maintenance and public use Trails should be made of porous materials

This Section from the Local Coastal Plan allows development to encroach within the 100-foot riparian setback provided the project is sited and designed to prevent impacts which would significantly degrade the riparian habitat Trails and access is permitted if studies determine there is no long-term adverse impacts due to construction maintenance and public use

June 19 2012 File No CPH09-007 Page 7 The proposed project includes a bridge with a wooden-deck to be installed over an unnamed tributary that flows through one of the State Parks properties (north of Bodega Dunes State Park) The 120-foot long bridge will minimize impacts to the surrounding willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only due to the removal of approximately 20 square feet of willowswoodlandriparian plants The Wetland Mitigation Enhancement and Habitat Restoration Plan requires native trees and shrubs be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement Issue 5 Impacts on Wetlands The proposed project will create temporary and permanent impacts to wetland habitat Temporary impacts will be the result of construction activities The wetlands under federal jurisdiction and those are state jurisdiction are located on the proposed trail and adjacent east and west side of the trail In the federal wetlands permanent impacts would be from the boardwalk footings In the state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections The boardwalks themselves will not result in permanent impacts to either federal or state wetlands because they will either be avoided or minimized as a result of the placement of boardwalks Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks are proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only State Wetlands Wetland areas under California Coastal Commission (CCC) jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock-aggregate shoulders Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub This area was likely coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhancement is to eliminate the invading coyote bush iceplant and non-native grasses and increase the native species cover and re-establish the coastal prairie community type The purpose and goal of

June 19 2012 File No CPH09-007 Page 8 enhancing the existing coastal scrub community by converting it to a native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition The proposed project will create the following temporary and permanent impacts to wetlands located on the project site Temporary Impacts Permanent Impacts Federal Wetlands 039 acres temporary impacts +-0003 acres permanent impacts (17080 square feet) (1410 square feet) State Wetlands 329 acres temporary impacts 139 acres permanent impacts (143314 square feet) (60436 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project (prepared by Jane Valerius dated February 2012) provides a Wetland Mitigation Enhancement Plan for the proposed project to compensate for the permanent loss of wetland habitat The Wetland Mitigation Enhancement Plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within United States Army Corps of Engineers (Army Corps) wetland areas The mitigation measures for the Mitigated Negative Declaration and the Wetland Mitigation Enhancement Plan are included in the conditions of approval The Wetland Mitigation Enhancement and Habitat Restoration Plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures will be conducted by Sonoma County Regional Parks to compensate for the permanent and temporary impacts to wetlands and riparian habitat 1 Enhance existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional

wetlands resulting in a minimum of 417 acres of wetland enhancement 2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses 3 Direct seeding the temporary construction areas with a seed mix based on the native grasses

forbs and flowers disturbed to construct the project 4 Direct seeding from seed and mulching of temporary construction areas along the trail and at

staging areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on-site

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Proposed Site Improvements Proposed development includes 10 miles of Class 1 bikeway consisting of an 8 foot wide stabilized aggregate pathway with a 120 foot long bridge and 918 lineal feet of boardwalk crossings over designated wetlanddrainage areas The project also includes two trailhead parking areas and minor improvements to Highway 1 The following is an expanded description of the proposed project improvements

Main Trail 4220 If of 8 wide stabilized aggregate Class 1 multi-use trail with 1 wide aggregate shoulder on one side and 3 aggregate shoulder on the other for equestrian use (50640 SF) 918 lineal feet of 8 wide raised boardwalks over wetland areas (7244 SF) and a 120 long and 8 wide bridge (960 SF)

Parking Areas There are two proposed parking areas and trailheads to serve the new facilities The main parking area is accessed from Highway 1 and includes 14 permeable and 1 paved disabled stall The access road and driveway access from State Highway 1 are paved and will include a pipe gate to restrict after operating hour access The total area of this parking lot a~ce~s road and amenities is approximately 17158 square feet of which approximately 13166 square feet is paved This parking area will also provide accessible paths of travel to facilities a 6 high wood enclosure to screen a portable restroom three family picnic sites a bike rack trash cans trail signage bollards and split rail fencing to restrict vehicles access and a pull in area for busses and emergency vehicles

The second parking area is located at Keefe Avenue at the northern terminus of the proposed project This trailhead will inclode 1 paved accessible parking space with an additional 6 permeable parallel parking spaces along the shoulder This trailhead will incorporate log barriers and bollards to restrict vehicle access onto the trail Trail signage and a trash receptacle will be provided at this trailhead

Highway 1 Improvements The initial comments fromCaltrans on the proposed driveway improvements on Highway 1 requested-we-inCiudean-8-foofwicfeescape routealorfgtne eastslioulaer ortnenignway--------shydirectlymiddot across from the dmiddotriveway entry This would allow through trafficto continue north if a vehicle was stopped to yield for south bound traffic prior to turning left into the parking lot The escape route would be 8 feet wide and 300 feet long There are 50 foot tapered sections at each end for transitioning off and back onto the highway There is a utility pole on the southwest side of the entry driveway that will need to be relocated to construct the entry improvements

Scenic Highway 1 Setback The proposed parking area is set back from Coast Highway 1 by 100 feet Existing trees will screen the majority of the paved areas The only structure proposed is a small 12 by 16 by 6 foot high wood enclosure to screen a portable restroom area from view The bike and pedestrian path wooden bridge and boardwalks are set back from highway 1 over 1800feet and at least partially obscured from view by existing vegetation and topography Refer to the Initial Study (Appendix B - Visual Checklist) for a description of visual impacts of the project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

The following provides the methods and treatments to be applied to the enhancement and restoration sites for mitigation of both permanent and temporary impacts from the proposed project Table 1 provides a list of plant species-that will be used for seeding and planting for wetland mitigation enhancement and grassland habitat restoration The species on the list are based on the plant surveys conducted for the project and all these species occur within the trail alignment

Figures 1 and 2 show the location of the mitigation sites and the associated existing plant community types along the trail Figures 3 and 4 show the plant species recommended for seeding All figures are provided as attachments at the end of this report Photographs of Sites A Band C are provided in Appendix A

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

bull Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method of control This method also leaves standing dead wood for wildlife habitat

bull Pile and burn This method is best used where there are many trees or woody species to be removed This is also the most labor intensive ofthe control measures

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

Mitigation enhancement Site C will be considered successful if after 3 years of monitoring

bull Iceplant jubata grass and other noxious weeds have been significantly reduced or eradicated from the site (80 or more reduction in cover)

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull Monterey Pine has been eliminated from the site However dead material will be left in place as snags anq for wildlife habitat

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Interim Performance Criteria

For each year that monitoring the data is collected the data will be compared to a baseline setmiddotof data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull The average total vegetation cover is 80 or greater absolute cover

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

30233 (a) The diking filling or dredging of open coastal waters wetlands estuaries and lakes shall be permitted in accordance with other applicable provisions of this division where there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects and shall be limited to the following

(7) Nature study aquaculture or similar resource-dependent activities

(c) In addition to the other provisions of this section diking filling or dredging in existing estuaries and wetlands shall maintain or enhance the functional capacity of the wetland or estuary Any alteration of coastal wetlands identified by the Department of Fish and Game including but not limited to the 19 coastal wetlands identified in its report entitled Acquisition Priorities for the Coastal Wetlands of California shall be limited to very minor incidental public facilities restorative measures nature study commercial fishing facilities in Bodega Bay and development in already developed parts of south San Diego Bay if otherwise in accordance with this division

This Section of the Coastal Plan allows filling of wetlands when there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects provided the use is nature study aquaculture or similar resource-dependent activities In addition this Section limits the fill of a wetland to very minor incidental public facilities The proposed project has been designed to avoid and minimize damage to wetlands Permanent impacts to the wetlands would be from the boardwalk footings and regular trail sections To offset the loss of the wetland Regional Parks is proposing to enhance the on-site existing wetland at a 31 ratio (see discussion listed below Issue 5) The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access In addition the Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system

Section III-2 of the Local Coastal Plan

30240 (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat values and only uses dependent on such resources shall be allowed within such areas

(b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation areas shall be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of such habitat areas

Wetlands are considered environmentally sensitive habitats in the Local Coastal Plan The trail has been designed to minimize impacts to existing wetlands as the impacts will occur to low quality wetlands The applicant is proposing to enhance on-site wetland habitat values at a 31 which is equal to approximately 417 acres of enhancement (see additional discussion listed below Issue 5) In addition a 185 acre of wetland enhancement will also take place on-site Section III-13 of the Local Coastal Plan

(24) Prohibit the removal of vegetation from wetlands unless it is shown to be essential to the habitat viability

(25) Prohibit construction of agricultural commercial industrial and residential structures within 100 feet of wetlands

(26) Between 100 and 300 feet of wetlands prohibit construction of agricultural commercial industrial and residential structures unless an environment assessment finds the wetland would not be affected by such construction

As previously stated the on-site wetland habitat will be enhanced at a 31 ratio and the proposed use is not an agricultural commercial industrial or residential the use is considered a recreational use The trail is a resource-dependent use as the nature trail provides coastal access to the public Riparian Habitat

Section III-12 Local Coastal Plan

(9) Prohibit construction of permanent structures within riparian areas as defined or 100 feet from the lowest line of riparian vegetation whichever is greater except development dependent on there sources in the riparian habitat including public recreation facilities related to the resource Any development shall be allowed only if it can be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of the riparian habitat The riparian area or 100 foot wide buffer zone should generally be maintained in a natural undisturbed state Trails and access may be permitted if studies determine no long-term adverse impacts would result from their construction maintenance and public use Trails should be made of porous materials

This Section from the Local Coastal Plan allows development to encroach within the 100-foot riparian setback provided the project is sited and designed to prevent impacts which would significantly degrade the riparian habitat Trails and access is permitted if studies determine there is no long-term adverse impacts due to construction maintenance and public use

June 19 2012 File No CPH09-007 Page 7 The proposed project includes a bridge with a wooden-deck to be installed over an unnamed tributary that flows through one of the State Parks properties (north of Bodega Dunes State Park) The 120-foot long bridge will minimize impacts to the surrounding willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only due to the removal of approximately 20 square feet of willowswoodlandriparian plants The Wetland Mitigation Enhancement and Habitat Restoration Plan requires native trees and shrubs be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement Issue 5 Impacts on Wetlands The proposed project will create temporary and permanent impacts to wetland habitat Temporary impacts will be the result of construction activities The wetlands under federal jurisdiction and those are state jurisdiction are located on the proposed trail and adjacent east and west side of the trail In the federal wetlands permanent impacts would be from the boardwalk footings In the state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections The boardwalks themselves will not result in permanent impacts to either federal or state wetlands because they will either be avoided or minimized as a result of the placement of boardwalks Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks are proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only State Wetlands Wetland areas under California Coastal Commission (CCC) jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock-aggregate shoulders Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub This area was likely coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhancement is to eliminate the invading coyote bush iceplant and non-native grasses and increase the native species cover and re-establish the coastal prairie community type The purpose and goal of

June 19 2012 File No CPH09-007 Page 8 enhancing the existing coastal scrub community by converting it to a native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition The proposed project will create the following temporary and permanent impacts to wetlands located on the project site Temporary Impacts Permanent Impacts Federal Wetlands 039 acres temporary impacts +-0003 acres permanent impacts (17080 square feet) (1410 square feet) State Wetlands 329 acres temporary impacts 139 acres permanent impacts (143314 square feet) (60436 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project (prepared by Jane Valerius dated February 2012) provides a Wetland Mitigation Enhancement Plan for the proposed project to compensate for the permanent loss of wetland habitat The Wetland Mitigation Enhancement Plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within United States Army Corps of Engineers (Army Corps) wetland areas The mitigation measures for the Mitigated Negative Declaration and the Wetland Mitigation Enhancement Plan are included in the conditions of approval The Wetland Mitigation Enhancement and Habitat Restoration Plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures will be conducted by Sonoma County Regional Parks to compensate for the permanent and temporary impacts to wetlands and riparian habitat 1 Enhance existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional

wetlands resulting in a minimum of 417 acres of wetland enhancement 2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses 3 Direct seeding the temporary construction areas with a seed mix based on the native grasses

forbs and flowers disturbed to construct the project 4 Direct seeding from seed and mulching of temporary construction areas along the trail and at

staging areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on-site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting

native trees and shrubs 6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct

seeding of native coastal prairie species south of the Bodega Dunes Park entrance road 7 Monitoring and following performance criteria for wetland enhancement for a minimum of three

years after all seeding planting and weed control activities have been completed

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

bull The average total vegetation cover is 80 or greater absolute cover

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

February 2012 22

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

June 19 2012 File No CPH09-007 Page 5 Public Facilities Zoning district allows any facility owned and operated by a city or the county as an allowed use without a Use Permit The proposed project will not have an effect on a Scenic Resource Combining District as the facilities will be screened by existing vegetation and natural terrain The materials used will blend in with the native surroundings as the aggregate used for the trail surface will be tinted an earth tone color and wood will be used for the boardwalks and bridge The trail will be constructed at grade following natural contours of the land The trailhead parking area accessed from Highway 1 will be well screened by existing vegetation Issue 4 Environmentally Sensitive Habitat Areas Wetlands The following policies from the Environmental Resources section of the Sonoma County Local Coastal Plan apply to the proposed project

Section III-1of the Local Coastal Plan

30233 (a) The diking filling or dredging of open coastal waters wetlands estuaries and lakes shall be permitted in accordance with other applicable provisions of this division where there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects and shall be limited to the following

(7) Nature study aquaculture or similar resource-dependent activities

(c) In addition to the other provisions of this section diking filling or dredging in existing estuaries and wetlands shall maintain or enhance the functional capacity of the wetland or estuary Any alteration of coastal wetlands identified by the Department of Fish and Game including but not limited to the 19 coastal wetlands identified in its report entitled Acquisition Priorities for the Coastal Wetlands of California shall be limited to very minor incidental public facilities restorative measures nature study commercial fishing facilities in Bodega Bay and development in already developed parts of south San Diego Bay if otherwise in accordance with this division

This Section of the Coastal Plan allows filling of wetlands when there is no feasible less environmentally damaging alternative and where feasible mitigation measures have been provided to minimize adverse environmental effects provided the use is nature study aquaculture or similar resource-dependent activities In addition this Section limits the fill of a wetland to very minor incidental public facilities The proposed project has been designed to avoid and minimize damage to wetlands Permanent impacts to the wetlands would be from the boardwalk footings and regular trail sections To offset the loss of the wetland Regional Parks is proposing to enhance the on-site existing wetland at a 31 ratio (see discussion listed below Issue 5) The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access In addition the Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system

Section III-2 of the Local Coastal Plan

30240 (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat values and only uses dependent on such resources shall be allowed within such areas

(b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation areas shall be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of such habitat areas

Wetlands are considered environmentally sensitive habitats in the Local Coastal Plan The trail has been designed to minimize impacts to existing wetlands as the impacts will occur to low quality wetlands The applicant is proposing to enhance on-site wetland habitat values at a 31 which is equal to approximately 417 acres of enhancement (see additional discussion listed below Issue 5) In addition a 185 acre of wetland enhancement will also take place on-site Section III-13 of the Local Coastal Plan

(24) Prohibit the removal of vegetation from wetlands unless it is shown to be essential to the habitat viability

(25) Prohibit construction of agricultural commercial industrial and residential structures within 100 feet of wetlands

(26) Between 100 and 300 feet of wetlands prohibit construction of agricultural commercial industrial and residential structures unless an environment assessment finds the wetland would not be affected by such construction

As previously stated the on-site wetland habitat will be enhanced at a 31 ratio and the proposed use is not an agricultural commercial industrial or residential the use is considered a recreational use The trail is a resource-dependent use as the nature trail provides coastal access to the public Riparian Habitat

Section III-12 Local Coastal Plan

(9) Prohibit construction of permanent structures within riparian areas as defined or 100 feet from the lowest line of riparian vegetation whichever is greater except development dependent on there sources in the riparian habitat including public recreation facilities related to the resource Any development shall be allowed only if it can be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of the riparian habitat The riparian area or 100 foot wide buffer zone should generally be maintained in a natural undisturbed state Trails and access may be permitted if studies determine no long-term adverse impacts would result from their construction maintenance and public use Trails should be made of porous materials

This Section from the Local Coastal Plan allows development to encroach within the 100-foot riparian setback provided the project is sited and designed to prevent impacts which would significantly degrade the riparian habitat Trails and access is permitted if studies determine there is no long-term adverse impacts due to construction maintenance and public use

June 19 2012 File No CPH09-007 Page 7 The proposed project includes a bridge with a wooden-deck to be installed over an unnamed tributary that flows through one of the State Parks properties (north of Bodega Dunes State Park) The 120-foot long bridge will minimize impacts to the surrounding willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only due to the removal of approximately 20 square feet of willowswoodlandriparian plants The Wetland Mitigation Enhancement and Habitat Restoration Plan requires native trees and shrubs be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement Issue 5 Impacts on Wetlands The proposed project will create temporary and permanent impacts to wetland habitat Temporary impacts will be the result of construction activities The wetlands under federal jurisdiction and those are state jurisdiction are located on the proposed trail and adjacent east and west side of the trail In the federal wetlands permanent impacts would be from the boardwalk footings In the state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections The boardwalks themselves will not result in permanent impacts to either federal or state wetlands because they will either be avoided or minimized as a result of the placement of boardwalks Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks are proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only State Wetlands Wetland areas under California Coastal Commission (CCC) jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock-aggregate shoulders Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub This area was likely coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhancement is to eliminate the invading coyote bush iceplant and non-native grasses and increase the native species cover and re-establish the coastal prairie community type The purpose and goal of

June 19 2012 File No CPH09-007 Page 8 enhancing the existing coastal scrub community by converting it to a native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition The proposed project will create the following temporary and permanent impacts to wetlands located on the project site Temporary Impacts Permanent Impacts Federal Wetlands 039 acres temporary impacts +-0003 acres permanent impacts (17080 square feet) (1410 square feet) State Wetlands 329 acres temporary impacts 139 acres permanent impacts (143314 square feet) (60436 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project (prepared by Jane Valerius dated February 2012) provides a Wetland Mitigation Enhancement Plan for the proposed project to compensate for the permanent loss of wetland habitat The Wetland Mitigation Enhancement Plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within United States Army Corps of Engineers (Army Corps) wetland areas The mitigation measures for the Mitigated Negative Declaration and the Wetland Mitigation Enhancement Plan are included in the conditions of approval The Wetland Mitigation Enhancement and Habitat Restoration Plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures will be conducted by Sonoma County Regional Parks to compensate for the permanent and temporary impacts to wetlands and riparian habitat 1 Enhance existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional

wetlands resulting in a minimum of 417 acres of wetland enhancement 2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses 3 Direct seeding the temporary construction areas with a seed mix based on the native grasses

forbs and flowers disturbed to construct the project 4 Direct seeding from seed and mulching of temporary construction areas along the trail and at

staging areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on-site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting

native trees and shrubs 6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct

seeding of native coastal prairie species south of the Bodega Dunes Park entrance road 7 Monitoring and following performance criteria for wetland enhancement for a minimum of three

years after all seeding planting and weed control activities have been completed

Whereas a Mitigated Negative Declaration was prepared for the Project and noticed and

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

February 2012 22

38

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Section III-2 of the Local Coastal Plan

30240 (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat values and only uses dependent on such resources shall be allowed within such areas

(b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation areas shall be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of such habitat areas

Wetlands are considered environmentally sensitive habitats in the Local Coastal Plan The trail has been designed to minimize impacts to existing wetlands as the impacts will occur to low quality wetlands The applicant is proposing to enhance on-site wetland habitat values at a 31 which is equal to approximately 417 acres of enhancement (see additional discussion listed below Issue 5) In addition a 185 acre of wetland enhancement will also take place on-site Section III-13 of the Local Coastal Plan

(24) Prohibit the removal of vegetation from wetlands unless it is shown to be essential to the habitat viability

(25) Prohibit construction of agricultural commercial industrial and residential structures within 100 feet of wetlands

(26) Between 100 and 300 feet of wetlands prohibit construction of agricultural commercial industrial and residential structures unless an environment assessment finds the wetland would not be affected by such construction

As previously stated the on-site wetland habitat will be enhanced at a 31 ratio and the proposed use is not an agricultural commercial industrial or residential the use is considered a recreational use The trail is a resource-dependent use as the nature trail provides coastal access to the public Riparian Habitat

Section III-12 Local Coastal Plan

(9) Prohibit construction of permanent structures within riparian areas as defined or 100 feet from the lowest line of riparian vegetation whichever is greater except development dependent on there sources in the riparian habitat including public recreation facilities related to the resource Any development shall be allowed only if it can be sited and designed to prevent impacts which would significantly degrade such areas and shall be compatible with the continuance of the riparian habitat The riparian area or 100 foot wide buffer zone should generally be maintained in a natural undisturbed state Trails and access may be permitted if studies determine no long-term adverse impacts would result from their construction maintenance and public use Trails should be made of porous materials

This Section from the Local Coastal Plan allows development to encroach within the 100-foot riparian setback provided the project is sited and designed to prevent impacts which would significantly degrade the riparian habitat Trails and access is permitted if studies determine there is no long-term adverse impacts due to construction maintenance and public use

June 19 2012 File No CPH09-007 Page 7 The proposed project includes a bridge with a wooden-deck to be installed over an unnamed tributary that flows through one of the State Parks properties (north of Bodega Dunes State Park) The 120-foot long bridge will minimize impacts to the surrounding willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only due to the removal of approximately 20 square feet of willowswoodlandriparian plants The Wetland Mitigation Enhancement and Habitat Restoration Plan requires native trees and shrubs be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement Issue 5 Impacts on Wetlands The proposed project will create temporary and permanent impacts to wetland habitat Temporary impacts will be the result of construction activities The wetlands under federal jurisdiction and those are state jurisdiction are located on the proposed trail and adjacent east and west side of the trail In the federal wetlands permanent impacts would be from the boardwalk footings In the state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections The boardwalks themselves will not result in permanent impacts to either federal or state wetlands because they will either be avoided or minimized as a result of the placement of boardwalks Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks are proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only State Wetlands Wetland areas under California Coastal Commission (CCC) jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock-aggregate shoulders Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub This area was likely coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhancement is to eliminate the invading coyote bush iceplant and non-native grasses and increase the native species cover and re-establish the coastal prairie community type The purpose and goal of

June 19 2012 File No CPH09-007 Page 8 enhancing the existing coastal scrub community by converting it to a native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition The proposed project will create the following temporary and permanent impacts to wetlands located on the project site Temporary Impacts Permanent Impacts Federal Wetlands 039 acres temporary impacts +-0003 acres permanent impacts (17080 square feet) (1410 square feet) State Wetlands 329 acres temporary impacts 139 acres permanent impacts (143314 square feet) (60436 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project (prepared by Jane Valerius dated February 2012) provides a Wetland Mitigation Enhancement Plan for the proposed project to compensate for the permanent loss of wetland habitat The Wetland Mitigation Enhancement Plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within United States Army Corps of Engineers (Army Corps) wetland areas The mitigation measures for the Mitigated Negative Declaration and the Wetland Mitigation Enhancement Plan are included in the conditions of approval The Wetland Mitigation Enhancement and Habitat Restoration Plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures will be conducted by Sonoma County Regional Parks to compensate for the permanent and temporary impacts to wetlands and riparian habitat 1 Enhance existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional

wetlands resulting in a minimum of 417 acres of wetland enhancement 2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses 3 Direct seeding the temporary construction areas with a seed mix based on the native grasses

forbs and flowers disturbed to construct the project 4 Direct seeding from seed and mulching of temporary construction areas along the trail and at

staging areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on-site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting

native trees and shrubs 6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct

seeding of native coastal prairie species south of the Bodega Dunes Park entrance road 7 Monitoring and following performance criteria for wetland enhancement for a minimum of three

years after all seeding planting and weed control activities have been completed

June 19 2012 File No CPH09-007 Page 9

In addition to the 417 acre of wetland enhancement listed above another 185 acre of wetland enhancement will also take place on-site The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Army Corps and Regional Water Quality Control Board (RWQCB) by January 31st of each year The first year annual report will be submitted after the first growing season after planting The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites Issue 6 Impacts on Riparian Habitat The proposed project will create temporary and permanent impacts to riparian habitat Temporary impacts are associated with construction activities and the areas will be restored to their pre-construction condition after construction activities are complete Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community at this location The proposed project will create the following temporary and permanent impacts to riparian habitat located on the project site Temporary Impacts Permanent Impacts Arroyo Willow temporary impacts 0022 acres permanent impacts 00003 acres Riparian Woodland (962 square feet) (126 square feet) Arroyo Willow temporary impacts 0015 acres permanent impacts 00002 acres Sedge Woodland (660 square feet) (70 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The previously mentioned Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project also provides a riparian mitigation enhancement plan for the proposed project to compensate for the permanent loss of riparian habitat The plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures that are included in the condition of approval 1 Plant native trees and shrubs at a 31 ratio based on trees removed from the riparian areas that

have a breast-height diameter of 6-inches or greater resulting in a minimum of 55 acres of riparian enhancement In the case of removal of non-native species a suitable native species will be selected for replanting

the Bodega Bay Coastal Prairie Trail Project located along a one mile route extending from 2255 Highway 1 to 100 Keefe Ave Bodega Bay APNs 100-220-008 100-230-001 100-230-042 100-020-019 101-020-042 101-020-043 101-020-044 and 101-020-045 Zoning PF (Public Facilities) CC (Coastal Combining) SR (Scenic Resources) and G (Geologic Hazard Area) Supervisorial District No 5 (the ldquoProjectrdquo) and

Whereas a Mitigated Negative Declaration was prepared for the Project and noticed and

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Resolution Date 6192012 Page 3

trees and shrubs will be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement

Be It Further Resolved the Board hereby grants the requested Coastal Permit subject to

Conditions of Approval in Exhibit ldquoArdquo attached hereto approves the Project and direct the Director of Sonoma County Regional Parks to take such action as may be necessary to carry out the Project

Be It Further Resolved that the Board of Supervisors designates the Clerk of the Board as the custodian of the documents and other material which constitute the record of proceedings upon which the decision herein is based These documents may be found at the office of the Clerk of the Board 575 Administration Drive Room 100-A Santa Rosa California 95403

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

February 2012 22

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

June 19 2012 File No CPH09-007 Page 7 The proposed project includes a bridge with a wooden-deck to be installed over an unnamed tributary that flows through one of the State Parks properties (north of Bodega Dunes State Park) The 120-foot long bridge will minimize impacts to the surrounding willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only due to the removal of approximately 20 square feet of willowswoodlandriparian plants The Wetland Mitigation Enhancement and Habitat Restoration Plan requires native trees and shrubs be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement Issue 5 Impacts on Wetlands The proposed project will create temporary and permanent impacts to wetland habitat Temporary impacts will be the result of construction activities The wetlands under federal jurisdiction and those are state jurisdiction are located on the proposed trail and adjacent east and west side of the trail In the federal wetlands permanent impacts would be from the boardwalk footings In the state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections The boardwalks themselves will not result in permanent impacts to either federal or state wetlands because they will either be avoided or minimized as a result of the placement of boardwalks Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks are proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only State Wetlands Wetland areas under California Coastal Commission (CCC) jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock-aggregate shoulders Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub This area was likely coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhancement is to eliminate the invading coyote bush iceplant and non-native grasses and increase the native species cover and re-establish the coastal prairie community type The purpose and goal of

June 19 2012 File No CPH09-007 Page 8 enhancing the existing coastal scrub community by converting it to a native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition The proposed project will create the following temporary and permanent impacts to wetlands located on the project site Temporary Impacts Permanent Impacts Federal Wetlands 039 acres temporary impacts +-0003 acres permanent impacts (17080 square feet) (1410 square feet) State Wetlands 329 acres temporary impacts 139 acres permanent impacts (143314 square feet) (60436 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project (prepared by Jane Valerius dated February 2012) provides a Wetland Mitigation Enhancement Plan for the proposed project to compensate for the permanent loss of wetland habitat The Wetland Mitigation Enhancement Plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within United States Army Corps of Engineers (Army Corps) wetland areas The mitigation measures for the Mitigated Negative Declaration and the Wetland Mitigation Enhancement Plan are included in the conditions of approval The Wetland Mitigation Enhancement and Habitat Restoration Plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures will be conducted by Sonoma County Regional Parks to compensate for the permanent and temporary impacts to wetlands and riparian habitat 1 Enhance existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional

wetlands resulting in a minimum of 417 acres of wetland enhancement 2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses 3 Direct seeding the temporary construction areas with a seed mix based on the native grasses

forbs and flowers disturbed to construct the project 4 Direct seeding from seed and mulching of temporary construction areas along the trail and at

staging areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on-site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting

native trees and shrubs 6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct

seeding of native coastal prairie species south of the Bodega Dunes Park entrance road 7 Monitoring and following performance criteria for wetland enhancement for a minimum of three

years after all seeding planting and weed control activities have been completed

June 19 2012 File No CPH09-007 Page 9

In addition to the 417 acre of wetland enhancement listed above another 185 acre of wetland enhancement will also take place on-site The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Army Corps and Regional Water Quality Control Board (RWQCB) by January 31st of each year The first year annual report will be submitted after the first growing season after planting The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites Issue 6 Impacts on Riparian Habitat The proposed project will create temporary and permanent impacts to riparian habitat Temporary impacts are associated with construction activities and the areas will be restored to their pre-construction condition after construction activities are complete Permanent impacts to the Arroyo WillowRiparian Woodland and Arroyo WillSedge Woodland riparian plant communities are associated with the bridge footings and boardwalk footings only Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community at this location The proposed project will create the following temporary and permanent impacts to riparian habitat located on the project site Temporary Impacts Permanent Impacts Arroyo Willow temporary impacts 0022 acres permanent impacts 00003 acres Riparian Woodland (962 square feet) (126 square feet) Arroyo Willow temporary impacts 0015 acres permanent impacts 00002 acres Sedge Woodland (660 square feet) (70 square feet) Wetland Mitigation Enhancement and Habitat Restoration Plan The previously mentioned Wetland Mitigation Enhancement and Habitat Restoration Plan for the Coastal Prairie Trail Project also provides a riparian mitigation enhancement plan for the proposed project to compensate for the permanent loss of riparian habitat The plan and the previously adopted Mitigated Negative Declaration require the following mitigation measures that are included in the condition of approval 1 Plant native trees and shrubs at a 31 ratio based on trees removed from the riparian areas that

have a breast-height diameter of 6-inches or greater resulting in a minimum of 55 acres of riparian enhancement In the case of removal of non-native species a suitable native species will be selected for replanting

Whereas a Mitigated Negative Declaration was prepared for the Project and noticed and

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Resolution Date 6192012 Page 3

trees and shrubs will be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement

Be It Further Resolved the Board hereby grants the requested Coastal Permit subject to

Conditions of Approval in Exhibit ldquoArdquo attached hereto approves the Project and direct the Director of Sonoma County Regional Parks to take such action as may be necessary to carry out the Project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

February 2012 22

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

the Bodega Bay Coastal Prairie Trail Project located along a one mile route extending from 2255 Highway 1 to 100 Keefe Ave Bodega Bay APNs 100-220-008 100-230-001 100-230-042 100-020-019 101-020-042 101-020-043 101-020-044 and 101-020-045 Zoning PF (Public Facilities) CC (Coastal Combining) SR (Scenic Resources) and G (Geologic Hazard Area) Supervisorial District No 5 (the ldquoProjectrdquo) and

Whereas a Mitigated Negative Declaration was prepared for the Project and noticed and

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Resolution Date 6192012 Page 3

trees and shrubs will be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement

Be It Further Resolved the Board hereby grants the requested Coastal Permit subject to

Conditions of Approval in Exhibit ldquoArdquo attached hereto approves the Project and direct the Director of Sonoma County Regional Parks to take such action as may be necessary to carry out the Project

Be It Further Resolved that the Board of Supervisors designates the Clerk of the Board as the custodian of the documents and other material which constitute the record of proceedings upon which the decision herein is based These documents may be found at the office of the Clerk of the Board 575 Administration Drive Room 100-A Santa Rosa California 95403

Biological Resources Impacts There are a number of biological resources that need to be protected during the implementation of this project Refer to the Initial Study document (Appendix C) for a complete discussion of biological resources impacts ami mitigation measures

Wetland Area Impacts Wetland delineation maps (Figures 1 and 2) biological resource reports (Appendix C) and a description of wetland impacts is included in the Initial Study document There will be permanent impacts to State wetlands of 139 acres We are proposing to mitigate these impacts with a 31 ratio of wetland enhancement within the project site Permanent Federal wetland impacts are less than 0003 and we are not proposing any mitigation for these impacts

Traffic Impacts A Traffic study was completed for the project August 18 2009 (See Initial Study Appendix G) The executive summary of this study identifies a less than significant traffic related project impact including the following descriptions

Access and Circulation With the removal of the existing power pole iocated along the west side of State Highway 1 across from the Caltrans maintenance facility driveway this proposed driveway location would have adequate sight distance in both directions To maintain adequate sight distance at the State Highway 1 project access driveway only low lying ground cover should be planted along the project frontage

Parking The proposed parking supply of 21 spaces is expected to adequately accommodate the projected parking demand generated by the proposed project

Cultural Resource Impacts A field survey and subsurface exploration found no evidence of prehistoric archaeological rEsources within the Area of Potential Effect (APF)--Refer-to AppenaiXDoftllelnitiarStuar---shyfor the complete cultural resources report

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

February 2012 18

34

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Interim Performance Criteria The interim performance criteria will be

bull Blue gum trees and jubata grass has been successfully eliminated from the mitigation site starting from year 1

bull Container plants if any are installed will have a 90 survival rate for the first year and 80 for the second year with 75 for the third year

Planting Stock Same criteria as described for final performance criteria

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the firstmiddotannual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site C

Final Performance Criteria

Mitigation enhancement Site C will be considered successful if after 3 years of monitoring

bull Iceplant jubata grass and other noxious weeds have been significantly reduced or eradicated from the site (80 or more reduction in cover)

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull Monterey Pine has been eliminated from the site However dead material will be left in place as snags anq for wildlife habitat

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Interim Performance Criteria

For each year that monitoring the data is collected the data will be compared to a baseline setmiddotof data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-native grasses Monterey pine and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Trail and Staging Area Restoration Including Boardwalk Areas

Final Performance Criteria

Trail and staging area restoration sites including boardwalk areas will be considered successful if after 3 years the total vegetation cover for the restoration sites is 80 or greater absolute cover and the restored areas h~ve similar cover values and species diversity as the surrounding plant communities

The adjacent plant community to the restored area will be sampled using the same methodology described below for the restoration areas This data will be the reference site data set and will be used to compare to the restoration area

A minimum of 20 randomly placed sample plots will be selected within each vegetation community type along the trail in both the restored area and adjacent plant community or reference area The restqration sites will be considered successful if after 3 years

bull The average total vegetation cover is 80 or greater absolute cover

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Resolution Date 6192012 Page 3

trees and shrubs will be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement

Be It Further Resolved the Board hereby grants the requested Coastal Permit subject to

Conditions of Approval in Exhibit ldquoArdquo attached hereto approves the Project and direct the Director of Sonoma County Regional Parks to take such action as may be necessary to carry out the Project

Be It Further Resolved that the Board of Supervisors designates the Clerk of the Board as the custodian of the documents and other material which constitute the record of proceedings upon which the decision herein is based These documents may be found at the office of the Clerk of the Board 575 Administration Drive Room 100-A Santa Rosa California 95403

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

The following provides the methods and treatments to be applied to the enhancement and restoration sites for mitigation of both permanent and temporary impacts from the proposed project Table 1 provides a list of plant species-that will be used for seeding and planting for wetland mitigation enhancement and grassland habitat restoration The species on the list are based on the plant surveys conducted for the project and all these species occur within the trail alignment

Figures 1 and 2 show the location of the mitigation sites and the associated existing plant community types along the trail Figures 3 and 4 show the plant species recommended for seeding All figures are provided as attachments at the end of this report Photographs of Sites A Band C are provided in Appendix A

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

4 little or no new growth apparent 5 healthy vigorous new growth

The survival rate for container stock planteq will be 75 at the end of 3 years ofmonitoring

Photos will be taken during the annual monitoring session at photo points and will be indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Interim Peiformance Criteria -Year One Percent absolute total vegetation cover is 50 or greater Year Two Percent absolute total vegetation cover is 70 or greater Year Three Percent absolute total vegetation cover is 80 or greater

Vegetation cover and species diversity will be compared to the adjacent plant community Each year there should be a trend that demonstrates that the restored (seeded and planted areas) have the same or similar plant species that reflect the surrounding plant community type

A minimum of 20 randomly placed sample plots will be selected within each vegetation community type along the trail The diversity of species will be the same or greater than the surrounding plant community For Corps wetland areas (boardwalk wetlands) the cover values will be based on cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Container plants if any are installed will have a 90 survival rate for the first year and 80 for the second year with 75 for the third year

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 eviderice of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or no new growth apparent 5 healthy vigorous new growth

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Resolution Of The Board Of Supervisors Of The County Of Sonoma State of California Approving The Proposed Bodega Bay Coastal Prairie Trail Project Located Along A One Mile Route Extending From 2255 Highway 1 To 100 Keefe Ave Bodega Bay APNs 100-220-008 100-230-001 100-230-042 100-020-019 101-020-042 101-020-043 101-020-044 And 101-020-045 Whereas the Sonoma County Regional Parks applied for a Coastal Permit to construct

the Bodega Bay Coastal Prairie Trail Project located along a one mile route extending from 2255 Highway 1 to 100 Keefe Ave Bodega Bay APNs 100-220-008 100-230-001 100-230-042 100-020-019 101-020-042 101-020-043 101-020-044 and 101-020-045 Zoning PF (Public Facilities) CC (Coastal Combining) SR (Scenic Resources) and G (Geologic Hazard Area) Supervisorial District No 5 (the ldquoProjectrdquo) and

Whereas a Mitigated Negative Declaration was prepared for the Project and noticed and

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Resolution Date 6192012 Page 3

trees and shrubs will be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement

Be It Further Resolved the Board hereby grants the requested Coastal Permit subject to

Conditions of Approval in Exhibit ldquoArdquo attached hereto approves the Project and direct the Director of Sonoma County Regional Parks to take such action as may be necessary to carry out the Project

Be It Further Resolved that the Board of Supervisors designates the Clerk of the Board as the custodian of the documents and other material which constitute the record of proceedings upon which the decision herein is based These documents may be found at the office of the Clerk of the Board 575 Administration Drive Room 100-A Santa Rosa California 95403

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

bull Monitor the re-vegetationplant community restoration for a three year period bull Replant as needed to achieve a 75 percent total survivability

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Resolution Of The Board Of Supervisors Of The County Of Sonoma State of California Approving The Proposed Bodega Bay Coastal Prairie Trail Project Located Along A One Mile Route Extending From 2255 Highway 1 To 100 Keefe Ave Bodega Bay APNs 100-220-008 100-230-001 100-230-042 100-020-019 101-020-042 101-020-043 101-020-044 And 101-020-045 Whereas the Sonoma County Regional Parks applied for a Coastal Permit to construct

the Bodega Bay Coastal Prairie Trail Project located along a one mile route extending from 2255 Highway 1 to 100 Keefe Ave Bodega Bay APNs 100-220-008 100-230-001 100-230-042 100-020-019 101-020-042 101-020-043 101-020-044 and 101-020-045 Zoning PF (Public Facilities) CC (Coastal Combining) SR (Scenic Resources) and G (Geologic Hazard Area) Supervisorial District No 5 (the ldquoProjectrdquo) and

Whereas a Mitigated Negative Declaration was prepared for the Project and noticed and

made available for agency and public review in accordance with the California Environmental Quality Act (ldquoCEQArdquo) and the State and County CEQA Guidelines and

Whereas A Mitigated Negative Declaration was previously adopted and approved by the

Sonoma County Board of Supervisors on June 21 2011 at a regularly scheduled public hearing The Board found the Project will not have a significant effect on the environment and

Whereas On May 15 2012 the Board of Supervisors took original jurisdiction over the

Project and Whereas in accordance with the provisions of law the Board of Supervisors held a

public hearing on June 19 2012 at which time all interested persons were given an opportunity to be heard and

Whereas the Board of Supervisors has had an opportunity to review this Resolution and

finds that it accurately sets forth the intentions of the Board regarding the Mitigated Negative Declaration and the Project

Now Therefore Be It Resolved that said Board of Supervisors makes the following

findings

1 The Project is consistent with the General Plan land use designation of PQP (Public and Quasi Public) as General Plan Land Use Policy 25 indicates the PQP designation is intended to provide sites that serve the community or public needs owned and operated by government agencies non-profit entities or public utilities Public parks and new trails intended to be used by the public is an allowed use in this land use designation

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Resolution Date 6192012 Page 3

trees and shrubs will be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement

Be It Further Resolved the Board hereby grants the requested Coastal Permit subject to

Conditions of Approval in Exhibit ldquoArdquo attached hereto approves the Project and direct the Director of Sonoma County Regional Parks to take such action as may be necessary to carry out the Project

Be It Further Resolved that the Board of Supervisors designates the Clerk of the Board as the custodian of the documents and other material which constitute the record of proceedings upon which the decision herein is based These documents may be found at the office of the Clerk of the Board 575 Administration Drive Room 100-A Santa Rosa California 95403

Proposed Site Improvements Proposed development includes 10 miles of Class 1 bikeway consisting of an 8 foot wide stabilized aggregate pathway with a 120 foot long bridge and 918 lineal feet of boardwalk crossings over designated wetlanddrainage areas The project also includes two trailhead parking areas and minor improvements to Highway 1 The following is an expanded description of the proposed project improvements

Main Trail 4220 If of 8 wide stabilized aggregate Class 1 multi-use trail with 1 wide aggregate shoulder on one side and 3 aggregate shoulder on the other for equestrian use (50640 SF) 918 lineal feet of 8 wide raised boardwalks over wetland areas (7244 SF) and a 120 long and 8 wide bridge (960 SF)

Parking Areas There are two proposed parking areas and trailheads to serve the new facilities The main parking area is accessed from Highway 1 and includes 14 permeable and 1 paved disabled stall The access road and driveway access from State Highway 1 are paved and will include a pipe gate to restrict after operating hour access The total area of this parking lot a~ce~s road and amenities is approximately 17158 square feet of which approximately 13166 square feet is paved This parking area will also provide accessible paths of travel to facilities a 6 high wood enclosure to screen a portable restroom three family picnic sites a bike rack trash cans trail signage bollards and split rail fencing to restrict vehicles access and a pull in area for busses and emergency vehicles

The second parking area is located at Keefe Avenue at the northern terminus of the proposed project This trailhead will inclode 1 paved accessible parking space with an additional 6 permeable parallel parking spaces along the shoulder This trailhead will incorporate log barriers and bollards to restrict vehicle access onto the trail Trail signage and a trash receptacle will be provided at this trailhead

Highway 1 Improvements The initial comments fromCaltrans on the proposed driveway improvements on Highway 1 requested-we-inCiudean-8-foofwicfeescape routealorfgtne eastslioulaer ortnenignway--------shydirectlymiddot across from the dmiddotriveway entry This would allow through trafficto continue north if a vehicle was stopped to yield for south bound traffic prior to turning left into the parking lot The escape route would be 8 feet wide and 300 feet long There are 50 foot tapered sections at each end for transitioning off and back onto the highway There is a utility pole on the southwest side of the entry driveway that will need to be relocated to construct the entry improvements

Scenic Highway 1 Setback The proposed parking area is set back from Coast Highway 1 by 100 feet Existing trees will screen the majority of the paved areas The only structure proposed is a small 12 by 16 by 6 foot high wood enclosure to screen a portable restroom area from view The bike and pedestrian path wooden bridge and boardwalks are set back from highway 1 over 1800feet and at least partially obscured from view by existing vegetation and topography Refer to the Initial Study (Appendix B - Visual Checklist) for a description of visual impacts of the project

Item 2 Proposal Statement

Biological Resources Impacts There are a number of biological resources that need to be protected during the implementation of this project Refer to the Initial Study document (Appendix C) for a complete discussion of biological resources impacts ami mitigation measures

Wetland Area Impacts Wetland delineation maps (Figures 1 and 2) biological resource reports (Appendix C) and a description of wetland impacts is included in the Initial Study document There will be permanent impacts to State wetlands of 139 acres We are proposing to mitigate these impacts with a 31 ratio of wetland enhancement within the project site Permanent Federal wetland impacts are less than 0003 and we are not proposing any mitigation for these impacts

Traffic Impacts A Traffic study was completed for the project August 18 2009 (See Initial Study Appendix G) The executive summary of this study identifies a less than significant traffic related project impact including the following descriptions

Access and Circulation With the removal of the existing power pole iocated along the west side of State Highway 1 across from the Caltrans maintenance facility driveway this proposed driveway location would have adequate sight distance in both directions To maintain adequate sight distance at the State Highway 1 project access driveway only low lying ground cover should be planted along the project frontage

Parking The proposed parking supply of 21 spaces is expected to adequately accommodate the projected parking demand generated by the proposed project

Cultural Resource Impacts A field survey and subsurface exploration found no evidence of prehistoric archaeological rEsources within the Area of Potential Effect (APF)--Refer-to AppenaiXDoftllelnitiarStuar---shyfor the complete cultural resources report

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

The following provides the methods and treatments to be applied to the enhancement and restoration sites for mitigation of both permanent and temporary impacts from the proposed project Table 1 provides a list of plant species-that will be used for seeding and planting for wetland mitigation enhancement and grassland habitat restoration The species on the list are based on the plant surveys conducted for the project and all these species occur within the trail alignment

Figures 1 and 2 show the location of the mitigation sites and the associated existing plant community types along the trail Figures 3 and 4 show the plant species recommended for seeding All figures are provided as attachments at the end of this report Photographs of Sites A Band C are provided in Appendix A

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

bull Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method of control This method also leaves standing dead wood for wildlife habitat

bull Pile and burn This method is best used where there are many trees or woody species to be removed This is also the most labor intensive ofthe control measures

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

bull Iceplant jubata grass and other noxious weeds have been significantly reduced or eradicated from the site (80 or more reduction in cover)

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull Monterey Pine has been eliminated from the site However dead material will be left in place as snags anq for wildlife habitat

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Interim Performance Criteria

For each year that monitoring the data is collected the data will be compared to a baseline setmiddotof data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull The average total vegetation cover is 80 or greater absolute cover

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Resolution Date 6192012 Page 2

2 General Plan Policy PF-2a of the Public Facilities and Services Element states to plan design and construct park and recreation fire and emergency medical public education and solid waste services and public utilities in accordance with projected growth The Coastal Prairie Trail is located within two existing public parks Bodega Dunes Regional Park and California State Parks and the new trail will benefit and be used by the general public

3 The Project is consistent with General Plan Policy OSRC-17d of the Open Space and Resource Conservation This policy states that trails on Figure OSRC-3 make up the Countys designated plan for trails The Sonoma Coast Trail is identified as a designated trail under this policy and extends from Black Point southward to the Estero Americano The Coastal Prairie Trail is located within the Sonoma Coast Trail

4 The Project is consistent with General Plan Policy CT-3v of the Circulation and Transit Element This policy states where a nexus exists require private or public development to plan design and construct bicycle and pedestrian facilities to integrate with the existing and planned bicycle and pedestrian network The Coastal Prairie Trail is integrated with existing bicycle and pedestrian networks located in two public parks will benefit and be used by the general public

5 The Project is consistent with General Plan Policy CT-3q of the Circulation and Transit Element This policy states to design construct and improve bikeways consistent with the Bikeways Plan ldquoProject Priority Listrdquo The Coastal Prairie Trail is a trail listed on the Bikeway Plan ldquoProject Priority Listrdquo and has been designed as an improved pedestrian bikeway and equestrian trail

6 The Project is consistent with the Coastal Land Use designation of Institutional Section VII-59 of the Local Coastal Plan defines Institutional uses as land accommodating institutional or public uses The project site is located in two public parks and the new trail will benefit and be used by the general public

7 The Project is consistent with the Coastal Zoning Ordinance designation of PF (Public Facilities) as the project is a public facility owned and operated by a city or in the county and meets all setback and height requirements

8 The Project is consistent with the Local Coastal Plan as the project has been designed to avoid and minimize damage to wetlands The Coastal Prairie Trail is a very minor incidental public facility located in two existing public parks and is a resource-dependent use as the use is a nature trail that provides coastal access The Coastal Prairie Trail is part of the ldquoSonoma Coast Trailrdquo which is part of a statewide coastal trail system To offset the take of the wetland the applicant is proposing to enhance the on-site existing wetland habitat values at a 31 ratio which is equal to approximately 417 acres of wetland enhancement

Trails are permitted to encroach into the 100 foot riparian setback provided the project is sited and designed to prevent impact which would significantly degrade the riparian habitat Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance will minimize impacts to the willow riparian community Native

Resolution Date 6192012 Page 3

trees and shrubs will be planted at a 31 ratio based on trees removed from the riparian areas This ratio will result in approximately 55 acres of on-site riparian enhancement

Be It Further Resolved the Board hereby grants the requested Coastal Permit subject to

Conditions of Approval in Exhibit ldquoArdquo attached hereto approves the Project and direct the Director of Sonoma County Regional Parks to take such action as may be necessary to carry out the Project

Be It Further Resolved that the Board of Supervisors designates the Clerk of the Board as the custodian of the documents and other material which constitute the record of proceedings upon which the decision herein is based These documents may be found at the office of the Clerk of the Board 575 Administration Drive Room 100-A Santa Rosa California 95403

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

bull Monitor the re-vegetationplant community restoration for a three year period bull Replant as needed to achieve a 75 percent total survivability

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

The following provides the methods and treatments to be applied to the enhancement and restoration sites for mitigation of both permanent and temporary impacts from the proposed project Table 1 provides a list of plant species-that will be used for seeding and planting for wetland mitigation enhancement and grassland habitat restoration The species on the list are based on the plant surveys conducted for the project and all these species occur within the trail alignment

Figures 1 and 2 show the location of the mitigation sites and the associated existing plant community types along the trail Figures 3 and 4 show the plant species recommended for seeding All figures are provided as attachments at the end of this report Photographs of Sites A Band C are provided in Appendix A

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

The following provides the methods and treatments to be applied to the enhancement and restoration sites for mitigation of both permanent and temporary impacts from the proposed project Table 1 provides a list of plant species-that will be used for seeding and planting for wetland mitigation enhancement and grassland habitat restoration The species on the list are based on the plant surveys conducted for the project and all these species occur within the trail alignment

Figures 1 and 2 show the location of the mitigation sites and the associated existing plant community types along the trail Figures 3 and 4 show the plant species recommended for seeding All figures are provided as attachments at the end of this report Photographs of Sites A Band C are provided in Appendix A

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

bull Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method of control This method also leaves standing dead wood for wildlife habitat

bull Pile and burn This method is best used where there are many trees or woody species to be removed This is also the most labor intensive ofthe control measures

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

bull Iceplant jubata grass and other noxious weeds have been significantly reduced or eradicated from the site (80 or more reduction in cover)

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull Monterey Pine has been eliminated from the site However dead material will be left in place as snags anq for wildlife habitat

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Interim Performance Criteria

For each year that monitoring the data is collected the data will be compared to a baseline setmiddotof data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

Trail and Staging Area Restoration Including Boardwalk Areas

Final Performance Criteria

Trail and staging area restoration sites including boardwalk areas will be considered successful if after 3 years the total vegetation cover for the restoration sites is 80 or greater absolute cover and the restored areas h~ve similar cover values and species diversity as the surrounding plant communities

The adjacent plant community to the restored area will be sampled using the same methodology described below for the restoration areas This data will be the reference site data set and will be used to compare to the restoration area

bull The average total vegetation cover is 80 or greater absolute cover

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

February 2012 22

38

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

Figures 1 and 2 show the location of the mitigation sites and the associated existing plant community types along the trail Figures 3 and 4 show the plant species recommended for seeding All figures are provided as attachments at the end of this report Photographs of Sites A Band C are provided in Appendix A

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Trail and Staging Area Restoration Including Boardwalk Areas

Final Performance Criteria

Trail and staging area restoration sites including boardwalk areas will be considered successful if after 3 years the total vegetation cover for the restoration sites is 80 or greater absolute cover and the restored areas h~ve similar cover values and species diversity as the surrounding plant communities

The adjacent plant community to the restored area will be sampled using the same methodology described below for the restoration areas This data will be the reference site data set and will be used to compare to the restoration area

A minimum of 20 randomly placed sample plots will be selected within each vegetation community type along the trail in both the restored area and adjacent plant community or reference area The restqration sites will be considered successful if after 3 years

bull The average total vegetation cover is 80 or greater absolute cover

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

bull Monitor the re-vegetationplant community restoration for a three year period bull Replant as needed to achieve a 75 percent total survivability

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Final Performance Criteria

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

Mitigation enhancement Site C will be considered successful if after 3 years of monitoring

bull Iceplant jubata grass and other noxious weeds have been significantly reduced or eradicated from the site (80 or more reduction in cover)

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull Monterey Pine has been eliminated from the site However dead material will be left in place as snags anq for wildlife habitat

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Interim Performance Criteria

For each year that monitoring the data is collected the data will be compared to a baseline setmiddotof data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

Trail and Staging Area Restoration Including Boardwalk Areas

Final Performance Criteria

Trail and staging area restoration sites including boardwalk areas will be considered successful if after 3 years the total vegetation cover for the restoration sites is 80 or greater absolute cover and the restored areas h~ve similar cover values and species diversity as the surrounding plant communities

The adjacent plant community to the restored area will be sampled using the same methodology described below for the restoration areas This data will be the reference site data set and will be used to compare to the restoration area

A minimum of 20 randomly placed sample plots will be selected within each vegetation community type along the trail in both the restored area and adjacent plant community or reference area The restqration sites will be considered successful if after 3 years

bull The average total vegetation cover is 80 or greater absolute cover

bull The diversity of species will be the same or greater than the surrounding plant community

bull Cover and diversity of native species is the same or greater than the adjacent reference site

bull Cover by invasive exotics plants like iceplant pampas grass and gorse is zero percent and cover by naturalized non-native grasses is less than or does not exceed that of the adjacent reference area It will not be possible to completely eliminate naturalized nonshynative grasses from the site if the adjacent area supports these naturalized non-native grasses

For Corps wetland areas (boardwalk wetlands) the cover value will be 80 absolute cover by F AC F ACW and OBL wetland plants

For areas planted using container stock the following criteria will be applied

Planting Stock Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss

ANNUAL REPORT PREPARATION AND SUBMITTAL

The mitigation sites will be monitored for a minimum of three years An annual report describing the monitoring efforts will be submitted to the CCC the Corps and Regional Water Quality Control Board (R W QCB) by January 31 st of each year The first year annual report will be submitted after the fir~t growing season after planting

The Annual Reports will include a description of the results of the vegetation monitoring including observations of the success of the herbicide treatments and any maintenance activities Photos of the site will also be included An analysis of the performance of the wetland enhancement and grassland restoration sites will also be provided in the report along with any recommendations for remedial measures that may need to be implemented to improve the performance of the mitigation sites

Notification of Completion

Sonoma County Regional Parks (Regional Parks) will notify the CCC Corps and RWQCB upon completion ofmonitoring activities The agencies will confirm that one or more of the mitigation elements have met the final success criteria and will provide written confirmation to Regional Parks that it is released from further performance monitoring and reporting for that mitigation element

February 2012 22

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

INTRODUCTION

Project Description

The Coastal Prairie Trail (CPT) will be a Class 1 bike path as defined by the Caltrans Highway Design Manual However it will function as a multi-use trail in that it will provide equitable access for all modes of trail use including bicycle pedestrian and equestrian The CPT will be approximately 10 miles in length and 12-feet wide The trail width includes an 8-foot wide trail with rockaggregate shoulders along each side of the trail Approximately 4230 feet of the trail will be surfaced with resin-stabilized aggregate The trail shoulders will be one-foot wide along one side of the trail and three-feet wide on the other side The three-foot wide shoulder will accommodate equestrian use The remaining sections of the main trial will consist of approximately 980 feet of boardwalk over wetlands within federal regulatory jurisdiction and a 120-foot long bridge of an unnamed tributary

The finished vertical profile of the cement-stabilized rock aggregate trail sections will be approximately 18-inches in depth The profile will include a 6-inch sub-base of scarified and recompacted native soil a 6 to 8-inch layer of compacted Class 2 aggregate base rock and a 2 to 4-inch section of compacted cement-stabilized rock aggregate The finished trail surface will be level with native ground The finished trail grade will be less than 5 percent rendering it compliant with American with Disabilities Act (ADA) and California Access Code title 24 standards There will be a 140-foot long section of rock aggregate trail at the southern trial tenninus This trail section will connect the CPT to the existing unpaved footpath that extends from the Bodega Bay Community Center to the Nicholas Green Bell Tower

Wetlands are located throughout the properties that comprise the project area Wetland delineations were conducted along the area ofpotential effect not on the entirety of the properties Some of the wetlands are within federal jurisdiction of the United States Army Corps of Engineers (USACOE) and all of the wetlands are within state jurisdiction of the California Coastal Commission (CCC) the difference being the number of parameters included in the determination1 Wetlands were surveyed as described in the USACOE Wetland Delineation Manual- Western Mountains Valleys and Coast Regional Supplement (2007) The USACOE verified the wetland delineation for the Coastal Prairie Trail project

The USACOE defines wetlands as areas that are inundated or saturated by surace or groundwater at a frequency and duration suffiCient to support and that under normal circumstances do support a prevalence avegetation typically adaptedor life in saturated soil conditions and by definition wetland determinations are made according to three criteria hydrophytic vegetation hydric soils and wetland hydrology

All of the proposed trail project areas are within the coastal zone and are therefore under the jurisdiction of the County of Sonomas Local Coastal Plan Under PRC Section 30121 in the Coastal Act Wetland means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes freshwater marshes open or closed brackish water marshes swamps mudflats andens The Coastal Act defines wetlands by the presence of any one of three wetland criteria (vegetation soils and hydrology) Therefore wetlands within the coastal zone often encompass a much broader area under the Coastal Act than compared with wetlands as defined by the USACOE

WETLAND IMPACTS

The acreages of permanent and temporary impacts to wetlands are included inTable 1 Federal wetlands are within the jurisdiction of the US Army Corps of Engineers State wetlands include federal jurisdiction wetlands and additional areas that meet the one-parameter criteria under the Coastal Commission guidelines for determining wetlands Temporary impacts will be the result of construction activities Permanent impacts are associated with permanent project elements In the federal wetlands permanent impacts would be from the boardwalk footings The boardwalks themselves will not result in permanent impacts to either federal or state wetlands For state wetlands permanent impacts would result from the boardwalk footings and the regular trail sections

139 acre

This project is subject to regulatory requirements from the US Army Corps ofEngineers the CA State Coastal Commission the CA Department ofFish and Game and the North Coast Regional Water Quality Control Board This wetland mitigation enhancement plan describes the proposed mitigation measures designed to compensate for impacts primarily to state wetlands since the federal wetlands will either be avoided or minimized as a result of the placement of boardwalks within USACOE wetland areas A description of each type is provided below

Federal Wetlands There are two sections of seasonal federal wetlands south of the Bodega Dunes Campground access road which together form a large horseshoe-shaped feature These are scrub-shrub dominated wetlands with the dominant indicator species including slough sedge (Carex obnupta) California blackberry (Rubus ursinus) and common velvet grass (Holcus lanatus) Boardwalks ar~ proposed to cross over the federal wetlands thereby avoiding impacts to these wetland areas (Figures 1 and 2) Placement of a bridge across the unnamed tributary drainage north of the Bodega Dunes Park entrance (Figure 1) will minimize impacts to the willow riparian community at this location Permanent impacts to the Arroyo WillowlRiparian Woodland and Arroyo WillowSedge Woodland plant communities are associated with the bridge footings and boardwalk footings only To mitigate for these impacts Sonoma County Regional Parks will

bull Plant native treesand shrubs at a 3 1 ratio based on trees removed from the riparian areas only that have a breast-height diameter of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting

bull Hydro-seed andor direct seed the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State Wetlands Wetland areas under CCC jurisdiction cannot be avoided because almost all of properties that compose the Coastal Prairie Trail project meet the Coastal Act wetland definition The trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants The proposed trail surface within state wetlands includes cement-stabilized aggregate with rock aggregate- shoulders Regional Parks cannot boardwalk the state wetland trail sections because of the relative cost of constructing boardwalk compared to constructing the reguhir trail sections The boardwalk will cost approximately $35 per square foot and the regular trail section will cost approximately $10 per square foot

Therefore the focus of this wetland enhancement and habitat restoration plan is to compensate for impacts to state wetlands and also for impacts for temporary construction activities

Summary of Proposed Mitigation Measures

Mitigation measures described in this plan include

1 Enhancing existing wetlands at a 31 ratio based on the permanent loss of state jurisdictional wetlands resulting in a minimum of417 acres of wetland enhancement

2 Wetland enhancement includes removal of coyote brush iceplant and non-native grasses

3 Direct seeding the temporary construction areas with a seed mix based on the native grasses forbs and flowers disturbed to construct the project

4 Direct seeding from seed and mulching of temporary construction areas along the trail and at staging areas with aseed mix based on the native grasses forbs and flowers disturbed to construct the project Seed mixes to be gathered from on site

5 Removal of non-native trees and jubata grass in the willow riparian community and planting native trees and shrubs

6 Removal of non-native trees such as Monterey pine and removal of coyote brush and direct seeding of native coastal prairie species south of the Bodega Dunes Park entrance road

7 Monitoring and following performance criteria for wetland enhancement for a minimum ofthree years after all seeding planting and weed control activities have been completed

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

GOALS OF MITIGATION

The following vegetation types have been mapped and identified for the Coastal Prairie Trail project area based on biological studies conducted for the project area (Figures 1 and 2) coastal prairie coastal scrub arroyo willow riparian cypress grove Monterey pine grove coyote brush and Army Corps Of Engineers (ACOE) jurisdictional wetland The trail runs through each of these vegetation types Impacts to the ACOE jurisdictional wetland type and arroyo willow riparian will be avoided and minimized by placement of a boardwalk for the wetlands and a bridge for the unnamed blue-line stream channel Because of the CCCs one-parameter test the vegetation types impacted by the trail also meet the CCC definition of wetland As mentioned previously the trail has been aligned to follow the contours of the site to the extent feasible to minimize cuts and fills and to pass through areas with higher concentrations of non-native plants to minimize impacts to native plants

Since it is not possible to create new CCC wetland communities the mitigation plan is designed to compensate for impacts to CCC wetlands by enhancing a 417 acre area that is currently mapped as coastal scrub (Figure 1) This area likely was coastal prairie before this area was invaded by coyote bush (Baccharis pilularis) This area also has been invaded by iceplant (Carpobrotus edulis) and is dominated by non-native grasses primarily velvet grass (Holcus lanatus) The focus of the enhance is to eliminate the invading coyote bush iceplant and nonshynative grasses and increase the native species cover and re-establish the coastal prairie community type

Areas that are temporarily impacted by trail construction which traverses all of the mapped vegetation community types will be restored to the adjacent surrounding community type

Functions and Values ofCoastal Prairie Grasslands

Representative plant species associated with the coastal prairie grasslands within the project area include native species such as California oatgrass (Danthonia californica) pacific reedgrass (Calamagrostis nutkaensis) tufted hairgrass (Deschampsia caespitosa ssp holciformis) and California blackberry (Rubus ursinus) However this grassland community has been invaded by non-native grasses such as velvet grass large quaking grass (Briza maxima) sweet vernal grass (Anthoxanthum odoratum) creeping bentgrass (Agrostis stolonifera) wild oats (Avena barbata and A fatua) dogtail grass (Cynosurus echinatus) bromes (Bromus diandrus and B hordaeceus) Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) Velvet grass a facultative wetland (F AC) plant species in particular is very common within the coastal prairie grassland community within the project area The coastal prairie grasslands in the southern portion of the trail have a mostly native species cover with some non-natives However in the northern portionofthe trail the native species cover drops significantly and cover by non-native grasses dominates

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

State-wide there has been a loss of native grasslands including coastal prairie grasslands primarily due to the introduction and spread of non-native grasses and other invasive exotic plant species (Barry et al 2006 Brooks 2001) Coastal prairie grassland provides habitat and foraging opportunities for a range ofwildlife species The grasses and herbaceous plants along with their associated invertebrates provide foraging opportunities for a variety of ground-foraging birds such as American robin sparrows dark-eyed junco northern flicker western meadowlark and numerous other resident and migratory birds Predatory hawks including northern harrier American kestrel white-tailed kite and red-shouldered and red-tailed hawks frequent these areas as well Small vertebrates and invertebrates within the habitat are likely to serve as a food source for these birds and other predatory vertebrates Subterranean foragers such as Bottas pocket gopher and California mole commonly occur in grassland habitats In addition small mice (eg deer and harvest) California vole black-tailed jackrabbit coyote and blacktailed deer are frequently observed Within the project site American badgers are actively using the habitat for burrowing and foraging Reptiles of this community include western fence lizard alligator lizard and snakes (eg gopher and garter) Bat species may also forage over this habitat (Prunuske Chatham Inc 2008)

Grasslands also provide essential hydrologic functions (capture storage and safe release of water) and are repositories ofnative flora diversity (Barry et aI2008) The acreage and quality of grassland habitats in California is increasingly reduced due to conversion to cropland residential and urban development and because of invasion by woody species and invasion by non-native herbaceous species (Barry et al 2008) Numerous interesting native grasses are found in all of Californias varied habitats from coastal dunes to tidal marshes to redwood forests (Brooks 2001) Over a hundred grass taxa occur on the North Coast several ofwhich are rare or endemic to the area (Brooks 2001)

The purpose and goal of enhancing the existing coastal scrub community to convert it to the native coastal prairie community is to enhance the functions and values of the site and return it to the native grassland condition

PROPOSEDmiddot MITIGATION SITES

Location of Mitigation Sites

A 417-acre site is proposed for mitigatiori for state designated wetlands within the Coastal Prairie Trail The mitigation site is located at the northern terminus of the proposed trail and is bounded on the north and east by the Keefe Avenue (Figure 1) The western edge of the mitigation site goes to th~ slight grade break and edge ofthe project study area This site meets the 31 mitigation ratio for permanent impacts described in the Mitigated Negative Declaration (MNDi for the project This mitigation site is shown as Mitigation Site A on Figure 1

Mitigation for temporary impacts will include restoration along the trail alignment of areas that will be temporarily disturbed as part of the trail creation including staging areas The total area of trail disturbance is 20-feet Twelve (12) feet will be the actual permanent trail with the remaining 8-feet of temporary disturbance to be restored There are also 12 staging areas along the trail that will be restored after construction is completed These areas are shown on Figures 1 and 2 and are designated as trail restoration areas

Two other sites shown as Mitigation Site B and C (Figures 1 and 2) will also receive treatments that will provide additional wetland mitigation enhancement as well as coastal prairie grassland restoration Mitigation Site B OSS-acres is located along the unnamed creek north ofBodega Dunes Park entrance driveway and is currently a well-developed willow riparian community Enhancement opportunities for this area include treatments to blue gum (Eucalyptus globulus) that are within the willow riparian canopy that will kill the tree but leave the trunk in place to provide wildlife habitat while reducing drawdown to the creek and removal ofjubata grass (Cortaderiajubata) In addition another non-native tree myoporum (Myoporum laetum) which occurs along the entrance road will be removed and replaced with an appropriate native species

Mitigation Site C 185 acres is located south of the Bodega Dunes Park entrance driveway will be enhanced using methods and techniques to reduce non-natives such a~ Monterey pine (Pinus radiata) and iceplant (Carpobrotus edulis) and also to remove coyote brush (Baccharis pilularis) which has become invasive in the areas Removal of these species will allow for establishment of more coastal prairie grassland and provide enhanced wildlife habitat

The following provides the methods and treatments to be applied to the enhancement and restoration sites for mitigation of both permanent and temporary impacts from the proposed project Table 1 provides a list of plant species-that will be used for seeding and planting for wetland mitigation enhancement and grassland habitat restoration The species on the list are based on the plant surveys conducted for the project and all these species occur within the trail alignment

Figures 1 and 2 show the location of the mitigation sites and the associated existing plant community types along the trail Figures 3 and 4 show the plant species recommended for seeding All figures are provided as attachments at the end of this report Photographs of Sites A Band C are provided in Appendix A

General Plant Community Enhancement and Restoration Measures

Seeds Plants and Cuttings In order to maintain the genetic integrity and diversity of native plants in the area revegetation will utilize on-site seed stock to the maximum extent possible Seed and plant sources utilized for wetland enhancement and plant community restoration will be in preferred order

1 All vegetation including seeds plants and cuttings will be salvaged from the construction area prior to soil disturbance for use in plant community enhancement and restoration This can occur by incrementally scraping soil including seed stock then stockpiling the material with a tarp cover as necessary to protect the soil and seed stock from adverse weather conditions until construction is complete Vegetation shall be separated from soil materials The stockpiled soil and seed will then be spread out onto any exposed areas within the enhancement and restoration sites

2 Seeds plants and cuttings can be collected from similar vegetation from the surrounding undisturbed plant community type Plant material can then be propagated from this stock

3 Seeds plants and cuttings could be collected off-site but from within 5 miles of the project site and i~ the same ecological region elevation and site characteristics as the site to be enhanced revegetated or restored Plant material can be propagated from this stock

4 Seeds plants and cuttings could be acquired from commercial sources provided that the material is within the same ecological region within 5 miles of the project site elevation and site characteristics as the site to be enhanced revegetated or restored

Invasive Species Management

The following measures will be implemented to minimize the spread of invasive species

1 Regional Parks or its contractor will remove gorse (Ulex europaea) within the areas disturbed by construction-related activities and in any mitigation enhancement or restoration areas

2 Regional Parks will require that plant materials removed as part of construction-related activities that includes invasive plant species be disposed off site in a manner that will not promote the spread or re-establishment of these species

3 Regional Parks or its contractor will restore areas of temporary disturbance to their preshyconstruction condition or better after construction activities are completed Restoration will include installation of sediment and erosion control as needed and seeding with a native seed mix specifically selected for the native plant communities present on site and that does not include species listed as noxious weeds

4 Regional Parks will monitor the areas disturbed by construction-related activities for the establishment of new or expanding populations of invasive species for a three year period following construction Monitoring will consist of semi-annual inspections Any new or expanding invasive species populations identified within the project area will be removed or controlled

5 Regional Parks will require the use of integrated pest management methods to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Mitigation Site A Wetland Enhancement Implementation

A 417 -acre site will be the focus for wetland mitigation for impacts to primarily coastal prairie grassland that also qualifies as state coastal wetlands Therefore the mitigation enhancement efforts will be to enhance and restore coastal prairie grassland species Photographs of this sitemiddot are provided in Appendix A This site has low growing coyote bush that is invading into the grassland and will be a target for removal There is also a significant cover by iceplant and nonshynative grasses specifically velvet grass These species are targeted for removal Native species present in the area include spreading rush (Juncus patens) California oatgrass (Danthonia californica) sword fern (Polystichum munitum) and California blackberry (Rubus ursinus)

A list of herbaceous coastal prairie plants to be seeded and targeted for Mitigation Site A is provided in Table 1

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site A are coyote bush iceplant and non-native grasses such -S velvet grass jubata grass and other incidental species

February 2012 11

27

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Control of coyote bush iceplant and non-native grass and herbaceous species will be done primarily using integrated pest management methods

Seeding After initial treatment s~me of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with seed mix provide in Table 1 Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) ofpure live seed (PIs) per acre ofnative grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Trail and Staging Area Restoration

The trail has been designed to fit into the existing contours but some grading and re-shaping will be necessary to get a maximum 5 grade Sheet flow will still be maintained and the area disturbed to construct the trail is indicated on the plans as extent of grading and limit of work These areas will generally just be re-seeded

Seeding Areas where vegetation has been removed and soil is exposed from project related construction activities along the trail and at the staging areas will be seeded with the grass mix provided in Table 1 A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 1 0 lbspls per acre of native herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre Where appropriate some shrubs may be planted A list of upland grasses and forbs along with a list of shrubs for general planting are also provided in Table 1 All seeded areas shall be covered with mulch frommiddoton site vegetation stockpiles

Seeds shall be hand broadcast and raked in to ensure adequate coverage by soil Seeding shall be installed by October 15

Tree and Shrub Plantings As stated in the Mitigated Negative Declaration (MND) impacts to the arroyo willow riparian community from placement of the bridge and to coastal scrub and coyote bush shrub land will be mitigated by replacing native trees and shrubs at a 3 1 ratio based on trees removed that have a diameter at breast height of 6-inches or greater In the case of removal of non-native species a suitable native species will be selected for replanting (see Table 1)

February 2012 12

28

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Tree and shrub planting stock shall receive protective hardware Plant protection hardware shall consist of collar and screen or Tubex Individual trees will be planted on 15 to 20 foot centers and shrub species will be planted on 6 to 8 foot centers

The plantings shall be maintained for three years following plant installation Each planting location shall have weeds removed from inside the planting collar or Tubex three times each year for three years followinginstallation Weed removal shall be performed at least once in the spring summer and fallwinter of each year

Protective screens shall be opened during the later portion of the first growing season to allow the plant to grow beyond the confines of the screen enclosure Open screens shall appear as an open cylinder to provide continued browse protection to the lower portion of the plant Screens collars and weed control fabric shall remain in place for 3 to 5 years following plant installation All protective treatments shall be removed at the conclusion of the specified maintenance period

Tree and shrub container plantings shall have a complete survival count each year during the three-year maintenance period The first count shall occur at the end of the first growing season The final count shall occur at the end of the third year maintenance period Monitoring reports shall include the survival percent cover and height of both tree and shrub species The number by species ofplants replaced an overview of the revegetation effort and the method used to assess these parameters shall alsobe included Photos from designated photo locations shall also be included

Mitigation Site B Willow Riparian Enhancement

6 Mitigation Site B is approximately 055 acres in size Areas impacted by the bridge placement will be seeded and planted and mulched as described in the previous section for the trail and staging area restoration Enhancement measures for the Mitigation Site B will be focuse~ on control of blue gum andjubata grass in addition to other non-native trees and noxious weeds Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Invasive Species Management

Blue gum trees within the stream bank area impact the hydrology of the creek by reducing the water capacity of the creek flow The recommended enhancement treatment measures for tree removal are

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

February 2012 13

29

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

Lop drop and scatter ofinvasive trees This method is good for removing small trees This involves cutting the tree flush to the ground and then cutting it into small pieces and scattering the pieces and allowing them to decompose over time This method can be used in conjunction with Pile and burn This method is best used where there are many trees or woody species to be removed and space does not allow scattering This is also the most labor intensive of the control measures

Hack and squirt This method involves digging out the root and putting a hatch in the root and spraying it with a 100 herbicide application Only 1 milliliter per one inch diameter at breast height is needed The caution for this method is that the herbicide can leach out so it cannot be applied if sensitive species are present The advantage is that this method does not leave a scar like for girdling and it a faster and more efficient method ofcontrol This method also leaves standing dead wood for wildlife habitat

Invasive plants such as gorse and jubata grass will be controlled using herbicide applications as described for Mitigation Site A Removal of invasive species will allow for natives to establish No additional seeding or planting is planned for Mitigation Site B

Mitigation Site C Coastal Prairie Grassland Restoration and Exotic Species Control

Mitigation Site is ISS-acre and is located south of the Bodega Dunes Park entrance road The focus for enhancement will be to enhance and restore coastal prairie grassland This area was selected for enhancement because Monterey Pine (Pinus radiata) and coyote bush have invaded into the native grassland in this area Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

A list ofherbaceous coastal prairie plants to be seeded is provided in Table 1 and is the same as for Mitigation Site A

Invasive Species Management

Plant species targeted for control and removal for Mitigation Site C are Monterey pine coyote brush iceplant and non-native grasses such as velvet grass andjubata grass Non-native weedy herbs will also be targeted for control and removal Control of non-native and invasive species (which include coyote bush) will be done primarily by integrated pest management methods

Monterey Pine Several methods can be used to control Monterey pine

Girdling This involves girdling the tree using a chain saw and cutting into the cambium The tree is left in place This creates snags for wildlife and is an efficient method of exotic species control Integrated pest management practices will be used to insure no regeneration takes place

Coyote Bush and Non-Native Grasses and Herbs

Integrated pest management methods will be used to minimize the control invasive species A qualified Pest Control Applicator must supervise any herbicide applications as recommended by a Licensed Pest Control Advisor

Treatment for coyote bush should be conducted in the mid to late sumri1er

Treatments for grasses and herbs should be conducted during the spring when the growth is most active

Seeding After herbicide application some of the dead material primarily areas covered by coyote bush shrubs and iceplant will be removed and the exposed areas seeded with a seed mixture appropriate to the site (see Table 1) Seed shall be hand broadcast and raked into the soil to ensure that the seed is adequately covered with soil Seeding shall be installed by October 15

A seed mixture of20 to 25 pounds (lbs) of pure live seed (PIs) per acre of native grasses from the list in Table 1 plus 5 to 10 lbspls per acre ofnative herbs will be used The total seed mix will be approximately 30 to 35 lbspls per acre

Non-native grasses that are sprayed will be left in place Over time the native species will invade into these sites and the non-native grass cover and presence will be reduced

Controlled Burn This area would also benefit by using controlled burn to manage non-native grasses and lowshygrowing coyote bush It would also open up the area for a greater diversity ofwildlife Controlled burns area only recommended for areas where there would not be any threat to

existing structures and oilly if all the appropriate measures are taken A burn permit must also be obtained from the California Department of Forestry and Fire Protection (CDF)

Rational for Expecting Success

The proposed measures to eliminate or significantly reduce invasive non-native species as well as the native coyote brush which for the coastal prairie grassland community to be enhance can be considered as an inva~ive species will open up areas for colonization by native species This will be further enhanced by seeding these areas with native grasses and herbs known to occur in the area

The performance criteria proposed are designed to be practical and achievable It is not reasonable to propose or assume that all of the non-native species can be eliminated However this plan provides measures for the reduction of the non-natives while enhancing opportunities for native species to establish

MONITORING

Regional Parks staff will monitor the mitigation sites annually in the late spring when annuals are still present and most plants are identifiable Annual monitoring will occur for three growing seasons after plant installation and may extend for five years if replacement planting is required after the three year monitoring period Monitoring methods will be as follows

Wetland Mitigation Enhancement Site A

Final Performance Criteria

The wetland mitigation enhancement Site A will be considered successful if

bull Iceplant and jubata grass have been eradicated from the site

bull Coyote bush has been significant reduced (80 or more reduction in cover) or eliminated from the site

bull After 3 years of integrated pest management and seeding the overall cover by native species has increased by 20 or greater absolute cover as compared to the existing overall cover by natives ~

bull There is a corresponding decrease of 20 or more of non-native grasses specifically velvet grass

The final performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

InterilJl Performance Criteria

For each year that monitoring data is collected the data will be compared to a baseline set of data that will be collected before construction occurs The comparison between the baseline (prior to any enhancement measures) and the monitoring year will provide information on how the enhancement measures are performing The goal is to reduce cover by non-native species component and coyote bush and to increase cover by natives species The interim performance criteria will be

bull Analysis of success of weed control efforts with reports on the success of these efforts based on a reduction or elimination of the target species

bull Analysis of percent of native species cover and establishment within the mitigation site Ideally native species cover should increase 5 to 10 each year until the 20 criteria is met or exceeded Performance criteria may be adjusted as baseline and annual monitoring data are collected that more realistically reflect the conditions on the site and ability to increase native species cover

February 2012 17

33

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

bull Each year of monitoring should show a trend of increasing native species cover and decreasing cover by non-natives and coyote bush If there is not a trend towards increased cover by natives and decreased cover by non-natives then additional herbicide applications and seeding will be implemented

Prior to weeding and seeding the site shall be sampled usingl-meter square sample plots (quadrats) A sufficient number of quadrats (sample points) will be collected to provide a representative sample of the entire area The percent cover by individual species will be recorded and this will provide the baseline cover values for species within Site A

After weed control and seeding activities have been implemented the site will be sampled again using the same methodology as for the baseline sampling The percent cover by individuals species will be recorded and compared to the baseline cover values This will provide an analysis for determining the success of the weed control treatments and seeding efforts At the end of the three years of monitoring the site will be considered successful if the above performance criteria are met If these criteria have not been met after 3 years the site will be sampled again after 5 years

Photos will be taken during the annual monitoring session at photo points which will indicated on a graphic for the first annual report to the California Coastal Commission Executive Director Photo points will be determined in the field once implementation is complete to ensure the most complete coverage of all site aspects

Mitigation Enhancement Site B

Enhancement and restoration activities for mitigation site B will be considered successful if

bull Blue gum tr~es have been successfully controlled by one of the control methods identified in the treatment measures such as girdling lopdropscatter hack and squirt andor pile and bUrn and

bull Jubata grass has been successfully eliminated from the mitigation site

bull Container plants if any are installed will have a 75 survival rate by the end of third year If a 75 survival rate is not met then additional plants will be installed and monitored for 3 more years

Planting Stock

Each container plant will be monitored for success utilizing the following rating system

0 dead or missing 1 main stem dead with emerging basal sprouts 2 evidence of deficiency or disease 3 low vitality with evidence of biomass loss 4 little or now new growth apparent 5 healthy vigorous new growth

Coastal Prairie Trail Wetland Mitigation Enhancement And Habitat Restoration Plan

MAINTENANCE

Regional Parks staff will maintain the mitigation enhancement and restoration sites until such time that all permit conditions have been met After permit closeout State Parks will maintain the mitigation enhancement and restoration areas on their property and Regional Parks will maintain the mitigation enhancement and restorations areas on theirs

Regular scheduled maintenance will include hand removal of non-native weeds The focus will be on regular weeding and the removal ofnon-native seedlings in the enhancement and restoration areas to ensure the success of the native plants ability to maintain a dominant foothold over non-natives within the restoration area

All tree and shrub container stock will be hand watered by the Regional Parks contractor for the three years of monitoring Hand watering will only occur in the dry season Plants will be installed in the wet season to take advantage of the natural rainfall and to reduce stress related to transplantation

The site will be inspected on a quarterly basis for any noxious weed infestations The mitigation sites will be visually inspected once each season

Trash from construction or other means will be removed and discarded off-site
