On January 30th, EPA Administrator Gina McCarthy announced phase II of the National Stormwater Calculator Climate Assessment Tool. The tool provides decision-makers with an easy-to-use, customizable resource to identify and incorporate green infrastructure and low impact development techniques to reduce storm water runoff. The updated tool includes changes in seasonal precipitation levels; the effects of more frequent, high-intensity storms; and changes in evaporation rates based on climate change scenarios validated by the Intergovernmental Panel on Climate Change. The Stormwater Calculator and Climate Assessment Tool package was originally mentioned as part of the President’s Climate Action Plan. The announcement was made during a keynote speech at the 14thNational Conference and Global Forum on Science, Policy, and the Environment.
