Title page SWCSession 235 Stormwater Calculator Demonstration

Unfortunately, representatives from the U.S. EPA were unable to present at WEFTEC 2013 due to the government shutdown. However, EPA has made this presentation on the National Stormwater Calculator available. The Stormwater Calculator is a desktop application designed to help city planners, landscape architects, developers, and property owners assess the runoff-reduction benefits of green infrastructure on specific sites. Taking into account local soil conditions, land cover, and historical rainfall records, the calculator will determine the annual amount and frequency of stormwater runoff from locations anywhere in the U.S. The tool can examine how stormwater runoff changes under different development and green infrastructure scenarios.
