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 qualityImprove fish and wildlife habitat Alleviate floodingEnhance community stewardship

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

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

Finding Restoration Opportunities is Challenging…
Landscape is dominated by built environmentComplicated mosaic of pervious and impervious areaNeed dozens, even hundreds of parcelsParcels need to be in the right place and have the right owners
Process of discovering these opportunities is watershed planning
Stormwater problems are real… and so are the solutionsWatershed Restoration Techniques
Watershed Planning
Customized road map
Lays out a prioritized approach
Applying some combination of restoration or protection tools
Achieve specific, local goals
1. Characterize watershed2. Classify & screen priority subwatersheds3. Identify protection & restoration opportunities4. Conduct detailed assessments5. Assemble recommendations into plan6. Determine if plan meets goals7. Implement the plan8. Evaluate over time
