SOMERSETT SOA BIOLOGICAL RESOURCES AND HABITAT EVALUATION REPORT

1 INTRODUCTION

A biological resources inventory and habitat evaluation was conducted for the Somersett SOA located in northwest Reno, Nevada (Study Area). The Study Area is a developed subdivision with common landscaped areas and a golf course. In addition, there are undeveloped areas on the perimeter of the Study Area, including a few small disconnected parcels. The purpose of this study was to identify sensitive biological resources that require protection measures during maintenance and disturbance activities to comply with local, state, and federal regulations. 1.1 Project Location and Study Area

The entire Study Area is located within the City of Reno in Washoe County, Nevada (Figure 1). The Study Area is located within all or portions of Sections 1, 2, 3, 10, 11, 12, 13, 14, and 15 of Township 19 North, Range 18 East and Section 35 of Township 20 North, 18 East, within the Mount Diablo Meridian. The Study Area encompasses approximately 1700 acres, which also includes the developed areas. Within the Study Area, the SOA area measures 761.25 acres and the Golf Course measures 189.95 acres, which are the areas subject to maintenance and disturbance activities. The Study Area does not include the Sierra Canyon Association Common Area. The Study Area are shown is shown on Figure 2. 1.2 Environmental Setting

The environmental setting of the Study Area is important to determine the potential for particular sensitive biological resources to occur. 1.2.1 Physiography and Climate

The Study Area is located on the western edge of the Great Basin in an area that is transitional between the Basin and Range and the Sierra Nevada structural provinces. The main elements of the present topography are clearly related to structures formed during the basin-and-range period of deformation. The northern part of the Truckee Meadows is a major structural basin while the Peavine Mountain Block is a structural high. Peavine Mountain occurs at the north end of the Carson Range and the Study Area is on the south flank of Peavine Mountain. The project elevation ranges between approximately 4900 feet and 5400 feet above mean sea level (amsl). Multiple ephemeral drainages are present that serve to drain the southern side of Peavine Mountain. The average high temperature is 91.7 degrees Fahrenheit in summer, and the average low is 20.9 in winter. Normally July is the hottest month and January is the coldest. December and January are the wettest months, with an average of 1.05 and 1.12 inches of precipitation per month, respectively (Western Regional Climate Center – Reno Tahoe International Airport – 1937 – 2016).

1.2.2 Hydrology and Surface Water Bodies

The Project is located within the USGS Hydrologic Unit Code (HUC) 10 City of Reno-Truckee River Watershed. Within the Study Area, all surface water flows south towards the Truckee River. The Study Area is highly developed and many of the natural surface water features have been modified around development. One spring reported on the National Hydrology Dataset is present in the northeastern portion of the Study Area as shown on Figure 2. 1.2.3 Soils

According to the Natural Resources Conservation Service (NRCS) Washoe County - South Soil Survey, there are 23 soil units within the Study Area. Soils are often critical in determining the potential for sensitive plant species to occur. Many of the natural soil properties have been altered in the Study Area due to development, but some non-disturbed areas are present. The three dominant soil units present that comprise of more than 66 percent of the Study Area include the following:

994 – Badland-Chalco-Verdico complex, 8 to 30 percent slopes: stony clay loam, clay, bedrock.

1050 – Waspo clay, 15 to 30 percent slopes: clay, bedrock. 1052 – Waspo-Rock outcrop complex, 30 to 50 percent slopes: stony clay, clay, bedrock.

A complete customized soil report and map for the Study Area is included in Appendix A for reference. 1.2.4 Vegetation

The vegetation structure in the Study Area has modified through historic fires, development, and other anthropogenic disturbances. The Southwest Regap vegetation map was referenced to verify vegetation communities; however, the map is outdated and does not reflect the current level of disturbance in the area. The main natural community mapped is the Inter-Mountain Basins Big Sagebrush Shrubland and other variable sagebrush communities, which are consistent with the observations made in the undeveloped areas in the Study Area. Some mall inclusions of Pinyon Juniper Woodland area also present. Figure 3 shows the Southwest Regap vegetation map.

2 METHODS

2.1 Pre‐field Review and Sensitive Species Habitat Evaluation

Existing literature was reviewed and data requests were sent to resource agencies for the purpose of identifying potential biological resources and special status species that have the potential to occur. The following data collection activities were conducted for characterizing potential habitat for special status species:

1. Requested a threatened and endangered species list from the United States Fish and Wildlife Service (USFWS) in 2017 and utilized the Information, Planning and Conservation System to perform a search for a site-specific list of federally endangered, threatened, or candidate species that have the potential to occur in 2017 (Appendix B);

2. Requested species data from the Nevada Natural Heritage Program (NNHP) (Appendix C);

3. Requested species data from the Nevada Department of Wildlife (NDOW) (Appendix D);

4. Reviewed the USFWS’ National Wetland Inventory Maps to determine if any mapped riparian or wetlands are present in the Project Area (Appendix E); and

5. Reviewed and evaluated additional sources of information including aerial photographs, USGS topographic maps, NRCS soils data, vegetation community mapping, and species accounts.

2.2 Field Assessment

Rubicon made several visits to the Study Area between September and December 2017 to assess and confirm habitat conditions. Pedestrian and vehicle surveys were conducted to assess representative areas of the Study Area. The entire Study Area was not surveyed as the purpose of this assessment was just to confirm habitat conditions to be able to assess what sensitive biological resources have the potential to occur or utilize the area.

3 RESULTS

The following section presents the results of the habitat evaluation and field assessment. 3.1 Resource Agency Data Review

The results of the site-specific requests and database queries for special status species known to occur or potentially occur within the Project Area from the USFWS, NNHP, and NDOW are summarized below. United States Fish and Wildlife Service The USFWS determined that four federally threatened, endangered, or candidate species may have the potential to occur within the Project Area or vicinity as follows:

North America Wolverine (Gulo gulo) Cui-ui (Chasmistes cujus) Lahontan cutthroat trout (Onocorhynchus clarkia henshawi) Webber’s Ivesia (Ivesia webberi)

No designated Critical Habitat for any species is present within the Project Area or vicinity. The official species letter generated for the Project is included in Appendix B for reference.

Nevada Natural Heritage Program

The NNHP searched the Study Area and a two-kilometer area around the Study Area for the documented occurrences of special status species. Based on the results, the following four species have been reported in the search area, none of which were documented directly in the Study Area.

Steamboat monkeyflower (Diplacus ovatus) Altered andesite popcorn flower (Plagiobothrys glomeratus) Townsend’s big-eared bat (Corynorhinus townsendii) Osprey (Pandion halitus)

The letter and list provided by NNHP is included in Appendix C for reference. Nevada Department of Wildlife

The Nevada Department of Wildlife helps manage game and non-game wildlife species in Nevada. The NDOW provided potential species that could occur or utilize the Study Area and a hour-mile radius. The only big game species expected to use the area is mule deer. No greater sage-grouse habitat is present within the area. Lahontan cutthroat trout is known to exist in the watershed, but no habitat is present within the Study Area. The NDOW reports multiple raptor species that have the potential to use the area. In addition, they list five reported nest sites within 10 miles of the Study Area, however, none of them are located within the Study Area.

3.2 Sensitive Species Habitat Evaluation

Based on the results of the agency data review and species lists and assessment of the environmental setting of the Study Area, a list of the potential for sensitive species to occur was developed. This list was used to guide the field assessment verify whether the habitat in the Study Area was suitable to support the species. Table 1 is a summary of this habitat evaluation.

3.3 Field Assessment

The field assessment focused on visiting representative habitat or unique habitat features identified during the desktop research and literature review. The following section describes the habitat features documented in the Study Area. 3.3.1 Golf Course Ponds and Drainage System

Two main golf course ponds are located within the upper golf course area. The NWI maps show these as freshwater wetland features, but they are man-made in nature. The two ponds are connected by a drainage channel that has riparian and wetland plant species. In addition, downgradient of the lower pond the drainage channel continues with riparian scrub vegetation. There are other smaller golf course ponds present in the development that are less vegetated. It is expected resident of migratory water fowl species may use these features for foraging or nesting.

Photo 3 – Drainage channel connecting two pond with riparian scrub vegetation. 3.3.2 Golf Course Underpass Tunnels

Two tunnels that connect the back nine golf course areas were assessed prior to annual cleaning and to document potential bat and avian habitat. Swallow nests and a sparrow nest were observed within the tunnels, as well as, some day bat roosting sites above the light fixtures.

3.3.3 Sagebrush Habitat

Based on the Southwest GAP vegetation data, there are multiple variations of sagebrush habitat within the Study Area. However, based on the overall site development and fragmented habitat, the sagebrush habitats observed were somewhat uniform with a few dominant shrub species (Big Sagebrush (Artemisia tridentata), Bitterbrush (Purshia tridentata), Rabbitbrush (Chysothamnus nauseosus). The understory in the areas closer to development had more non-native grass and forb species, for example cheatgrass (Bromus tectorum), whereas the areas around the perimeter of the Study Area still had some native understory intact. Various native bird and other wildlife species are dependent on sagebrush habitat for their life cycles, but this habitat type is common and widespread within and outside of the Study Area.

Photo 5 – Typical sagebrush habitat 3.3.4 Pinyon‐Juniper Habitat

Pinyon-juniper habitat areas were observed mostly in drainage areas or areas where soils stay moister throughout the year. The trees in this habitat can provide additional cover for mule deer to bed down, nesting sites for migratory birds and raptors, and general wildlife cover and foraging. 3.3.5 Rock Outcrops

There are a few prominent rock outcrops within the Study Area. These areas are considered unique wildlife habitat features as they provide cover, protection, nesting and roosting sites for various species including sensitive bat species. The rock outcrops observed were not large enough to support any maternal roost sites or hibernacula, but rather day roosting.

The National Hydrography Data Set and topographic maps identified one spring site within the Study Area. Spring areas provide a wildlife water resource and additional foraging and nesting opportunities in an otherwise xeric environment.

14

3.3.7 Drainage Areas

The overall development of the area has left many ephemeral drainages intact. These drainage areas act as wildlife corridors for wildlife species to move through the area and from the Peavine Mountain area down to the Truckee River. In addition, there are two main drainage networks that may physically connect or are indicated as part of the Truckee River Watershed. The drainages appear to have been preserved and enhanced as part of the master development and allow for recharge of groundwater and riparian vegetation to persist. These drainage areas offer refuge and a water source for wildlife.

4 CONCLUSIONS AND RECOMMENDATIONS

The following conclusions are presented:

The majority of the Study Area is developed with residential housing and golf course features. Pockets of native vegetation are present within the SOA and on the perimeter where it is undeveloped.

Wildlife and plant species observed were typical of northern Nevada habitats and urbanareas.

No suitable habitat was present for any special status wildlife species identified by resourceagencies to have the potential to occur.

Marginal habitat exists within small areas of the Study Area with andesitic soils forWebber’s Ivesia, but no known populations have been reported in the Study Area.

No raptor nests were reported within the Study Area.

The following recommendations are presented:

No additional focused or protocol-level surveys are recommended for plant and wildlifespecies.

A nesting bird survey should be conducted during avian breeding season to comply withthe Migratory Bird Treaty Act prior to any activities that would disturb vegetation ornesting habitat. Based on the location and elevation of the Study Area, this season typicallyruns from March through August.

Pond and tunnel maintenance activities are recommended to be conducted outside of themigratory bird nesting season.

Special wildlife use areas, including rock outcrops, drainage and riparian areas, and thespring area, are recommended to be protected from major vegetation or soil disturbance ifpossible.

If major work is required in drainage areas that connect to the Truckee River, additionalstate and federal permits may be required as they may be considered Waters of the Stateand Waters of the US. This study did not include a formal determination of jurisdiction andit is possible the original master plan permits have these activities permitted.

Best management practices should be employed to prevent the introduction and spread ofnon-native plant species, including the washing of equipment before and after use whentraversing on off road areas and using a weed-free seed mix for revegetation.

PrefaceSoil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment.

Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations.

Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?cid=nrcs142p2_053951).

Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations.

The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey.

Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are MadeSoil surveys are made to provide information about the soils and miscellaneous areas in a specific area. They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity.

Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA.

The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape.

Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries.

Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil

5

scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research.

The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas.

Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape.

Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties.

While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil.

Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date.

After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and

identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

Map Unit DescriptionsThe map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit.

A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils.

Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape.

The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas.


12

An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities.

Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement.

Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.

Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups.

A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.

An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.

An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.

Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

Subject: List of threatened and endangered species that may occur in your proposed projectlocation, and/or may be affected by your proposed project

To Whom It May Concern:

The attached species list indicates threatened, endangered, proposed, and candidate species anddesignated or proposed critical habitat that may occur within the boundary of your proposedproject and/or may be affected by your proposed project. The species list fulfills therequirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of theEndangered Species Act of 1973, as amended (ESA, 16 U.S.C. 1531 .), for projects that areet seqauthorized, funded, or carried out by a Federal agency. Candidate species have no protectionunder the ESA but are included for consideration because they could be listed prior to thecompletion of your project. Consideration of these species during project planning may assistspecies conservation efforts and may prevent the need for future listing actions. For additionalinformation regarding species that may be found in the proposed project area, visit

.http://www.fws.gov/nevada/es/ipac.html

The purpose of the ESA is to provide a means whereby threatened and endangered species andthe ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) ofthe ESA and its implementing regulations (50 CFR 402 .), Federal agencies are required toet sequtilize their authorities to carry out programs for the conservation of threatened and endangeredspecies and to determine whether projects may affect threatened and endangered species and/ordesignated critical habitat.

A Biological Assessment is required for construction projects that are major Federal actionssignificantly affecting the quality of the human environment as defined in the NationalEnvironmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major constructionactivities, the Service suggests that a biological evaluation similar to a Biological Assessment be

09/13/2017 Event Code: 08ENVD00-2017-E-01459 2

prepared to determine whether the project may affect listed or proposed species and/ordesignated or proposed critical habitat. Guidelines for preparing a Biological Assessment can befound at: .http://www.fws.gov/midwest/endangered/section7/ba_guide.html

If a Federal action agency determines, based on the Biological Assessment or biologicalevaluation, that listed species and/or designated critical habitat may be affected by the proposedproject, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition,the Service recommends that candidate species, proposed species, and proposed critical habitatbe addressed within the consultation. More information on the regulations and procedures forsection 7 consultation, including the role of permit or license applicants, can be found in the"Endangered Species Consultation Handbook" at:

.http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF

New information based on updated surveys, changes in the abundance and distribution ofspecies, changed habitat conditions, or other factors could change this species list. Please feelfree to contact us if you need more current information or assistance regarding the potentialimpacts to federally listed, proposed, and candidate species and federally designated andproposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulationsimplementing section 7 of the ESA, the accuracy of this species list should be verified after 90days. This verification can be completed formally or informally, as desired. The Servicerecommends that verification be completed by visiting the ECOS-IPaC website at regularintervals during project planning and implementation, for updates to species lists andinformation. An updated list may be requested through the ECOS-IPaC system by completingthe same process used to receive the attached list.

The Nevada Fish and Wildlife Office (NFWO) no longer provides species of concern lists. Mostof these species for which we have concern are also on the Animal and Plant At-Risk TrackingList for Nevada (At-Risk list) maintained by the State of Nevada's Natural Heritage Program(Heritage). Instead of maintaining our own list, we adopted Heritage's At-Risk list and arepartnering with them to provide distribution data and information on the conservation needs forat-risk species to agencies or project proponents. The mission of Heritage is to continuallyevaluate the conservation priorities of native plants, animals, and their habitats, particularly thosemost vulnerable to extinction or in serious decline. In addition, in order to avoid future conflicts,we ask that you consider these at-risk species early in your project planning and exploremanagement alternatives that provide for their long-term conservation.

For a list of at-risk species by county, visit Heritage's website ( ). For ahttp://heritage.nv.govspecific list of at-risk species that may occur in the project area, you can obtain a data requestform from the website ( ) or by contacting the Administrator ofhttp://heritage.nv.gov/get_dataHeritage at 901 South Stewart Street, Suite 5002, Carson City, Nevada 89701-5245, (775)684-2900. Please indicate on the form that your request is being obtained as part of yourcoordination with the Service under the ESA. During your project analysis, if you obtain newinformation or data for any Nevada sensitive species, we request that you provide theinformation to Heritage at the above address.

Furthermore, certain species of fish and wildlife are classified as protected by the State of

Please be aware that bald and golden eagles are protected under the Bald and Golden EagleProtection Act (16 U.S.C. 668 .), and projects affecting these species may requireet seqdevelopment of an eagle conservation plan (

). Additionally, wind energy projectshttp://www.fws.gov/windenergy/eagle_guidance.htmlshould follow the Service's wind energy guidelines ( ) forhttp://www.fws.gov/windenergy/minimizing impacts to migratory birds and bats.

The Service's Pacific Southwest Region developed the Interim Guidelines for the Development(Interimof a Project Specific Avian and Bat Protection Plan for Wind Energy Facilities

Guidelines). This document provides energy facility developers with a tool for assessing the riskof potential impacts to wildlife resources and delineates how best to design and operate a bird-and bat-friendly wind facility. These Interim Guidelines are available upon request from theNFWO. The intent of a Bird and Bat Conservation Strategy is to conserve wildlife resourceswhile supporting project developers through: (1) establishing project development in an adaptivemanagement framework; (2) identifying proper siting and project design strategies; (3) designingand implementing pre-construction surveys; (4) implementing appropriate conservationmeasures for each development phase; (5) designing and implementing appropriatepost-construction monitoring strategies; (6) using post-construction studies to better understandthe dynamics of mortality reduction ( , changes in blade cut-in speed, assessments of bladee.g.“feathering” success, and studies on the effects of visual and acoustic deterrents) includingefforts tied into Before-After/Control-Impact analysis; and (7) conducting a thorough riskassessment and validation leading to adjustments in management and mitigation actions.

The template and recommendations set forth in the Interim Guidelines were based upon theAvian Powerline Interaction Committee's Avian Protection Plan template ( )http://www.aplic.org/developed for electric utilities and modified accordingly to address the unique concerns of windenergy facilities. These recommendations are also consistent with the Service's wind energyguidelines. We recommend contacting us as early as possible in the planning process to discussthe need and process for developing a site-specific Bird and Bat Conservation Strategy.

The Service has also developed guidance regarding wind power development in relation toprairie grouse leks (sage-grouse are included in this). This document can be found at: http://www.fws.gov/southwest/es/Oklahoma/documents/te_species/wind%20power/prairie%20grouse%20lek%205%20mile%20public.pdf.

Migratory Birds are a Service Trust Resource. Based on the Service's conservationresponsibilities and management authority for migratory birds under the Migratory Bird TreatyAct of 1918, as amended (MBTA; 16 U.S.C. 703 .), we recommend that any land clearing et seqor other surface disturbance associated with proposed actions within the project area be timed toavoid potential destruction of bird nests or young, or birds that breed in the area.

destruction may be in violation of the MBTA. Under the MBTA, nests with eggs or young ofmigratory birds may not be harmed, nor may migratory birds be killed. Therefore, werecommend land clearing be conducted outside the avian breeding season. If this is not feasible,we recommend a qualified biologist survey the area prior to land clearing. If nests are located, orif other evidence of nesting ( , mated pairs, territorial defense, carrying nesting material,i.e.transporting food) is observed, a protective buffer (the size depending on the habitatrequirements of the species) should be delineated and the entire area avoided to preventdestruction or disturbance to nests until they are no longer active.

Appendix D Nevada Department of Wildlife Data Request Letter

Melissa Wendt September 19, 2017 Principal Rubicon Environmental Consulting 401 Court St. Reno, Nevada 89501 Re: Somersett SOA Dear Melissa Wendt: I am responding to your request for information from the Nevada Department of Wildlife (NDOW) on the known or potential occurrence of wildlife resources in the vicinity of the Somersett SOA located in Washoe County, Nevada. In order to fulfill your request an analysis was performed using the best available data from the NDOW’s wildlife occurrences, raptor nest sites and ranges, greater sage-grouse leks and habitat, and big game distributions databases. No warranty is made by the NDOW as to the accuracy, reliability, or completeness of the data for individual use or aggregate use with other data. These data should be considered sensitive and may contain information regarding the location of sensitive wildlife species or resources. All appropriate measures should be taken to ensure that the use of this data is strictly limited to serve the needs of the project described on your GIS Data Request Form. Abuse of this information has the potential to adversely affect the existing ecological status of Nevada’s wildlife resources and could be cause for the denial of future data requests. To adequately provide wildlife resource information in the vicinity of the proposed project the NDOW delineated an area of interest that included a four-mile buffer around the project area provided by you on Wednesday, September 13, 2017. Wildlife resource data was queried from the NDOW databases based on this area of interest. The results of this analysis are summarized below. Big Game - Occupied mule deer distribution exists within portions of the project area and four-mile buffer area. No known occupied bighorn sheep, elk, or pronghorn antelope distributions exist in the vicinity of the project area. Please refer to the attached maps for details regarding big game distributions relative to the proposed project area. Greater Sage-Grouse - There is no known greater sage-grouse habitat in the vicinity of the project area. Lahontan Cutthroat Trout - are known to exist in the vicinity of the project area in the City of Reno-Truckee River watershed. Raptors - Various species of raptors, which use diverse habitat types, may reside in the vicinity of the project area. American kestrel, bald eagle, barn owl, burrowing owl, Cooper's hawk, ferruginous hawk, flammulated owl, golden eagle, great horned owl, long-eared owl, merlin, northern goshawk, northern harrier, northern pygmy owl, northern saw-whet owl, osprey, peregrine falcon, red-tailed hawk, rough-legged hawk, sharp-shinned hawk, short-eared owl, Swainson's hawk, turkey vulture, and western screech owl have distribution ranges that include the project area and four-mile buffer area. Furthermore, the following raptor species have been directly observed in the vicinity of the project area: American kestrel merlin red-tailed hawk bald eagle northern goshawk sharp-shinned hawk

Additional species have also been observed in the vicinity of the project area. Please refer to the appendix for details regarding these species. The proposed project area may also be in the vicinity of abandoned mine workings, which often provide habitat for state and federally protected wildlife, especially bat species, many of which are protected under NAC 503.030. To request data regarding known abandoned mine workings in the vicinity of the project area please contact the Nevada Division of Minerals (http://minerals.state.nv.us/). The above information is based on data stored at our Reno Headquarters Office, and does not necessarily incorporate the most up to date wildlife resource information collected in the field. Please contact the Habitat Division Supervising Biologist at our Western Region Reno Office (775.688.1500) to discuss the current environmental conditions for your project area and the interpretation of our analysis. Furthermore, it should be noted that the information detailed above is preliminary in nature and not necessarily an identification of every wildlife resource concern associated with the proposed project. Consultation with the Supervising Habitat biologist will facilitate the development of appropriate survey protocols and avoidance or mitigation measures that may be required to address potential impacts to wildlife resources.

Mark Freese - Western Region Supervising Habitat Biologist (775.688.1145) Federally listed Threatened and Endangered species are also under the jurisdiction of the United States Fish and Wildlife Service. Please contact them for more information regarding these species.
