DESCRIPTION

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 DEEP’s web site, and it will also be placed on the City of Bridgeport’s 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 [email protected] and Erik Mas at [email protected] 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 stakeholder’s agreement and the transition plans to the Greater Bridgeport Regional Planning Agency.

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

Today’s Agenda

Page 3: Power Point Presentation Pequonnock River Watershed Management Plan Power Point 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

Page 4: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

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

Page 5: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

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

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

Page 9: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

Other Issues Facing the Pequonnock River• Flooding• Degraded habitat• Altered stream corridor• River “disconnected” from

the public• Development pressure

Page 10: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

Draft Watershed Management Plan• Plan development

process• Goals and objectives• Recommended actions• Site-specific project

concepts• Pollutant load reductions• Responsible entities,

timeframes, products• Funding sources

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

Page 14: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

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

Page 15: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

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

Page 16: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

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

Page 17: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

• Low Impact Development (LID) and Green Infrastructure

• Implement stormwater retrofits• Require LID for new development

and redevelopment

Page 19: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

• CSO LTCP – augment grey with green

• Build on City’s existing initiatives– Green Streets– Urban forestry and City parks– B-Green rain barrel program– CFE “Green Scan” Project– Regulatory updates to promote GI

and LID

Green Infrastructure for CSO Control

Protect and Restore Stream Buffers

◄ Upper West Branch

Williams Road, Trumbull ►

◄ Upper Pequonnock River

Upper West Branch ►

• Implement priority stream buffer restoration projects• Adopt local stream buffer requirements

Page 21: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

Habitat Protection and RestorationGoal: Protect and improve terrestrial, riparian, and

aquatic habitat in the watershed to maintain and increase the watershed’s 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

Page 22: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

• Protect and restore aquatic and stream corridor habitat– Remove stream barriers (Pequonnock River Apron Fishway

project, Bunnell’s Pond Dam eel pass modifications)– Implement priority stream erosion and restoration projects

Protect and Restore Forests and Tree Canopy

• Consider developing local tree protection ordinances– Hartford Tree Ordinance– NYC Million Trees Initiative

• Implement reforestation/tree canopy demonstration projects

• Bridgeport Urban Tree Canopy (UTC) Analysis

Page 26: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

Sustainable Land Use and Open Space

Goal: Promote sustainable growth and appropriate development in the watershed while preserving and improving the watershed’s 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

Page 27: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

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

Site-specific Retrofitand Restoration Concepts

Page 31: Power Point Presentation Pequonnock River Watershed Management Plan Power Point Presentation

Retrofit Screening Approach• Retrofit Types

– Green Infrastructure– Low Impact Development– Buffer Restoration– Stream Restoration

• Selection Factors– Proximity to streams– Public land ownership– High visibility, “demonstration” value– Applicability to other areas of watershed

• Address pollutants through treating and infiltrating stormwater

• Focus - Bacteria

Trumbull Library

• Centrally-located• Landscaped grounds with dense tree canopy• Site shared with Town Hall• More dedicated parking desired, but expansion would impact tree

canopy• Town representatives working to strike a balance between parking,

trees, stormwater, and cost
