2 Wet Weather Green Infrastructure (GI) Infrastructure associated with stormwater management and low impact development that encompasses approaches and technologies to infiltrate, evapotranspire, capture, and reuse stormwater to maintain or restore natural hydrologies. 2

3 that which we call a rose, by any other name would smell as sweet. Environmental Protection Conservation Sustainability Smart Growth Stormwater Management Best Management Practices 3

4 Green Infrastructure Includes Downspout Disconnection Rainwater Harvesting Rain Gardens Planter Boxes Bioswales Permeable Pavement Green Alleys and Streets Green Parking Green Roofs Urban Tree Canopy Land Conservation Green roof at the Friends Center, Philladelphia Permeable Pavement and Rain Gardens, Cincinnati State 4

5 Why Green Infrastructure? 1972 Clean Water Act National CSO Control Strategy CSO Control Policy: CSOs are point sources subject to NPDES permit requirements including both technology-based and water quality-based requirements of the CWA. In developing its long-term CSO control plan, the Permittee will employ a public participation process that actively involves the affected public in the decision-making to select long-term CSO controls EPA Administrator Gina McCarthy 7 Themes, 2 of which refer specifically to Green Infrastructure: Protecting Water A Precious Limited Resource to employ green infrastructure and other locally driven solutions that restore degraded waterways and revitalize communities CSO #5, Cincinnati MSD Making A Visible Difference in Communities Across the Country support green infrastructure to manage urban waters 5

6 Distribution of Communities with Combined Sewer Systems Combined sewer systems serve roughly 772 communities containing about 40 million people. Most communities with combined sewer systems (and therefore with CSOs) are located in the Northeast and Great Lakes regions, and the Pacific Northwest. 6

8 Green Infrastructure; EPA ORD Research Programs Of six total ORD Research Programs, Green Infrastructure is prominent in two: Safe and Sustainable Water Research Program Sustainable and Healthy Communities Research Program Green infrastructure is an approach that communities can choose to maintain healthy waters, provide multiple environmental benefits and support sustainable communities. By weaving natural processes into the built environment, green infrastructure provides not only stormwater management, but also flood mitigation, air quality management, and much more.
