Green Roofs Mean Less Polluted Runoff
- "In 2006, The American Society of Landscape Architects (ASLA) replaced the conventional roof on its downtown Washington, DC headquarters with a green roof, installing equipment to gather data on stormwater runoff, water quality, and temperature. From July 2006 to May 2007, ASLAs green roof prevented 27,500 gallons of stormwater -- nearly 75 percent of all precipitation on the roof -- from flowing into Washington, DCs overburdened sewer and stormwater system." - excerpt from this American Society of Landscape Architects web page.
