Stormwater discharges continue to cause impairment of our Nation’s waterbodies. In order to reduce impairment, EPA has developed the National Stormwater Calculator (SWC) to help support local, state and national stormwater management objectives and regulatory efforts to reduce runoff through infiltration and retention using green infrastructure (infrastructure based on natural processes) practices as low impact development (LID) controls.  The primary focus of the SWC is to inform site developers on how well they can meet a desired stormwater retention target with and without the use of green infrastructure. It can also be used by landscapers and homeowners. The SWC is a Windows-based desktop program that requires an internet connection. A mobile web application version that will be compatible with all operating systems will be released this fall.
