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
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
