Recent Switch to “Green” or Natural Systems • Green Infrastructure • Porous Pavement • Rain Gardens • Vegetated curb extensions • Tree trenches • Stormwater planters • Cisterns • Vegetated roofs Green Water Street Design, Syracuse, New York, USA Go to http://savetherain.us/ for more information
Recent Switch to “Green” or Natural Systems— A Balanced Green-Gray Approach • Gray Infrastructure: • Commitment to 88.7% annual volume capture in Gray Infrastructure by 2013 • Green Infrastructure: • Commitment to an additional 6.3% annual volume capture in Green Infrastructure commencing immediately in 2009, resulting in 95% total annual volume capture by 2018 Go to http://savetherain.us/ for more information
A Balanced Green-Gray Approach • Benefit to Water Quality • Selected Gray Projects maximize storage for advanced treatment at Metro • By managing stormwater before it gets into the Combined Sewer System, • Green Infrastructure eliminates pollutants at the source and reduces discharge volumes to the creek and lake • Also reduces flooding and erosion
Side Benefits of Green • Create Habitat and preserve biodiversity • Improve air quality • Improve neighborhood aesthetics • Create jobs and job training programs • Increase property values • Enhance community health and vitality
Further Needs • Non-Point science and monitoring method • Integrated planning efforts: incorporating water quality, habitat creation and urban revitalization goals in planning process
