E – 3018 Stormwater Calculator: Guide and Application

Managing stormwater effectively is essential for sustainable site development and flood prevention. The National Stormwater Calculator (SWC) is a powerful web-based tool developed by the U.S. Environmental Protection Agency (EPA) that estimates runoff, retention, and low-impact development (LID) performance for any location in the U.S. This course provides a step-by-step guide to using the SWC, participants will learn how to assess hydrological conditions, incorporate climate projections, and apply LID controls to enhance site resilience. Whether you are an engineer, planner, or property developer, this course will empower you to make data-driven decisions in stormwater management.
