  3. What is Restoration? Determined on case-by-case basis For many vision may look like: Swimmable and Fishable In order to achieve vision, goals may look like: Improve water quality Improve fish and wildlife habitat Alleviate flooding Enhance community stewardship

  4. Watershed Restoration Practices Stormwater Retrofits Stream Restoration Riparian Management Pervious Area Management Discharge Prevention Pollution Source Control Municipal Practices

  5. Stormwater Retrofits Stormwater best management practices (BMPs) inserted in an altered landscape where little or no prior stormwater controls existed Large storage BMPs On-site vegetated BMPs Residential BMPs

  30. Pollution Source Control Practices that focus educational, enforcement, and technical resources on changing resident behaviors or business operations that are causing pollution Residential Source Control Hotspot Source Control

  31. Bronx River Watershed, Westchester County, NY Residential Neighborhoods: • Focus on buffer encroachment and yard waste dumping • Increase watershed-related signage • Opportunities for rooftop disconnection, storm drain stenciling, and better lawn & landscaping practices Stormwater Hotspots: • Focus on municipal maintenance yards • Improve pollution prevention at gas stations and shopping centers • Explore County-wide illicit discharge coordination opportunities

  32. Discharge Prevention Practices that prevent sewage and other pollutants from entering the stream from illicit discharges Illicit Sewage Connections Commercial & Industrial Illicit Connections Failing Sewage Lines Industrial and Transport Spills

  33. Ohio IDDE Guidance Manual Inspecting and Developing Priority Areas Tracing For the Source of an Illicit Discharge Eliminating an Illicit Discharge Evaluating your IDDE Program Educating Public Employees, General Public, and Businesses

  34. Municipal Practices and Programs Improved operation and maintenance of publicly-owned facilities and infrastructure that will reduce pollution generation Street and Storm Drain Practices Best Practices for Development or Redevelopment Stewardship of Public Lands Municipal Stewardship Programs Watershed Education and Enforcement

  35. Montgomery County, MD Implement stormwater management and watershed restoration practices to manage 20% of the County’s impervious area Achieve pollutant reduction goals set forth in Total Maximum Daily Loads (TMDLs) for bacteria, sediment, nutrients, and trash Meet commitments in Trash Free Potomac Treaty Increase the use of Environmental Site Design (ESD) in new and redevelopment Assure public input and stewardship opportunities

  36. Finding Restoration Opportunities is Challenging… Landscape is dominated by built environment Complicated mosaic of pervious and impervious area Need dozens, even hundreds of parcels Parcels need to be in the right place and have the right owners Process of discovering these opportunities is watershed planning

  37. Watershed Planning Customized road map Lays out a prioritized approach Applying some combination of restoration or protection tools Achieve specific, localgoals 1. Characterize watershed 2. Classify & screen priority subwatersheds 3. Identify protection & restoration opportunities 4. Conduct detailed assessments5. Assemble recommendations into plan 6. Determine if plan meets goals 7. Implement the plan 8. Evaluate over time
