Powerpoint Presentation accompanying the presentation of the Draft Pequonnock River Watershed Management Plan. Public Comment will be accepted through Aug. 16. The draft watershed plan will be placed on the Connecticut DEEPs web site, and it will also be placed on the City of Bridgeports web site. We encourage general public comments for consideration. We will take public comments through August 16th, and responses should be sent to Chris Cryder at ccryder@savethesound.org and Erik Mas at EMas@fando.comOur next PRI Steering Committee meeting will be on Tuesday, August 30th, at 8:30 am, place TBD. It will most likely be in Monroe. At this meeting we will review the public and Steering Committee comments, and the second draft of the watershed plan. The goal will be to finalize and accept the watershed plan. Additionally, we will talk about any updates on the status of the stakeholders agreement and the transition plans to the Greater Bridgeport Regional Planning Agency.


Pequonnock River Draft Watershed Management PlanPequonnock River Initiative July 26, 2011

Todays Agenda Background Summarize Draft Plan Begin Comment Period Q&A After Presentation

Why Water Quality Matters Human Life and Healthy Communities Need Clean Water Great Communities Develop Sustainable Water Resources Focal Point for Urban/Suburban Community Collaboration Regional Economic Prosperity

Watershed Management Flexible framework for addressing water quality issues within a defined watershed or drainage area Stakeholder involvement Management actions supported by science Multiple political jurisdictions Prioritize limited financial resources EPA and CTDEP watershed approach

Why Develop a Watershed Plan? Watershed activities affect water quality Address water quality impairments Develop and implement a comprehensive, science-based management plan Improve chances of future funding and successful implementation

Statewide Trend Towards Watershed Planning

Issues Facing the Pequonnock River Water Quality in 80% of the river and in Bridgeport Harbor does not meet State standards for recreation or habitat Historical urban land use Bacteria and other pollutants Combined Sewer Overflows Stormwater runoff

Other Issues Facing the Pequonnock River Flooding Degraded habitat Altered stream corridor River disconnected from the public Development pressure

Recommended Actions Over 100 specific actions TimeframeOngoingYear 2 Year 5 Year 10

ShortTerm Next 1-2 Years

Mid-Term 2-5 Years

Long-Term 5-10 Years

Requires a coordinated effort by many groups PRI, watershed organization, municipalities, businesses, land owners

Capacity BuildingGoal: Build a foundation for successful implementation of the watershed management plan Objective 1: Establish a watershed organization Objective 2: Identify and secure funding Objective 3: Promote regional collaboration Objective 4: Continue watershed field assessments

Capacity Building - Highlights Municipal adoption of plan MOA, inter-municipal agreement, compact Form a watershed organization Partnership or coalition Greater Bridgeport Regional Planning Agency

Prepare and submit grant applications Develop web site and social media tools

Water QualityGoal: Improve the water quality of the Pequonnock River, its tributaries, and Bridgeport Harbor Objective 1: Continue monitoring programs Objective 2: Use LID/GI to address stormwater & CSOs Objective 3: Comply with existing permits Objective 4: Protect and restore riparian buffers Objective 5: Reduce septic system impacts Objective 6: Reduce impacts from nuisance waterfowl Objective 7: Identify and remove illicit discharges Objective 8: Reduce pollution from hotspots

Water Quality Monitoring Program Establish ongoing monitoring program Continue monitoring at Harbor Watch/River Watch and CT DEEP stations Expand monitoring to other reaches Consider RBV monitoring Involve volunteers, students, local universities Seek dedicated funding

Stormwater Management Low Impact Development (LID) and Green Infrastructure Implement stormwater retrofits Require LID for new development and redevelopment

Habitat Protection and RestorationGoal: Protect and improve terrestrial, riparian, and aquatic habitat in the watershed to maintain and increase the watersheds diversity of plant and animal species Objective 1: Protect and restore in-stream and riparian habitat Objective 2: Protect and restore forests and urban tree canopy Objective 3: Control invasive species Objective 4: Reduce illegal dumping locations

Fisheries and Stream Restoration Protect and restore aquatic and stream corridor habitat Remove stream barriers (Pequonnock River Apron Fishway project, Bunnells Pond Dam eel pass modifications) Implement priority stream erosion and restoration projects

Sustainable Land Use and Open SpaceGoal: Promote sustainable growth and appropriate development in the watershed while preserving and improving the watersheds natural resources, providing public access to open space, and addressing current and future flooding problems Objective 1: Promote sustainable growth and economic development Objective 2: Address flooding issues Objective 3. Protect and acquire open space Objective 4. Continue development of a greenway network Objective 5. Increase public access to the river corridor

Strengthen Land Use Regulations Stream Buffers Stormwater Management Tree Protection Groundwater and Drinking Water Supplies Open Space Consider formation of Regional WPCA Reduce or eliminate septic systems Potential mechanism for regional stormwater utility
