Impact/Purpose:
Use to help demo the USEPA National Stormwater Calculator.
Description:
This poster will demonstrate how EPA's National Stormwater Calculator works. The National Stormwater Calculator (SWC) estimates the amount of stormwater runoff generated from a site under different development and control scenarios over a long period of historical rainfall. The analysis takes into account local soil conditions, slope, land cover and meteorology. The SWC’s primary focus is informing site developers and property owners on how well they can meet a desired stormwater retention target. To help control runoff, seven different low impact development (LID) controls can be selected for use throughout the site. These controls are green infrastructure practices that help the user determine the best way to mimic natural water flow processes to retain rainfall onsite. Future climate change scenarios taken from internationally recognized climate change projections can also be considered.
