1. Southeast Michigan Watersheds SEMCOG Office February 10, 2015 Detroit, MI Green Infrastructure Target Setting Pilot Project

2. MDNR MDOT Partners in the Application MDEQ SEMCOG EPA Technical Assistance Funding ► “Southeast Michigan Watersheds Green Infrastructure Target Setting, will develop stormwater runoff volume reduction targets in the SEM region to achieve identified biological communities. Given these targets, alternatives for green infrastructure implementation will be explored and evaluated. “

3. Green Infrastructure Targeting Identify & Evaluate GI O PPORTUNITIES Outcome-based Areas of Opportunity Project Feasibility Strategic Framework Subwatershed Analysis Pre-planning

4. Pre-planning Task 1 Baseline Curves Pilot Areas Green Infrastructure Targeting

5. Pre-planning Task 2: Stormwater Runoff Volume Targets Green Infrastructure Targeting Richards-Baker Flashiness Index = 0.35 to 0.45

6. Task 2: Stormwater Targets Flashiness related to: Pre-planning Biology

7. Task 2: Stormwater Targets Flashiness also related to: Pre-planning Impervious Cover Key hydrologic metrics (e.g., volume, peak rate)

8. Can include: Alternatives to Achieve Targets Managing effective impervious cover Improving soil health Increasing tree canopy Implementing volume / peak flow BMPs

9. GI Vision: Red Run Areas of Opportunity
