EPA kicks off third-annual Campus RainWorks Challenge to develop innovative approaches to stormwater management
WASHINGTON, D.C. — The U.S. Environmental Protection Agency (EPA) released phase II of the National Stormwater Calculator and Climate Assessment Tool package. The updated calculator includes future climate vulnerability scenarios. The calculator is a desktop application that estimates the annual amount of stormwater runoff from a specific location. The Calculator now includes changes in seasonal precipitation levels, the effects of more frequent high-intensity storms, and changes in evaporation rates based on validated Intergovernmental Panel on Climate Change climate change scenarios.
