Stormwater Calculator: Guide and Application

Author: Roman Titov
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.

Learning Objectives

This course is intended to provide you with the following specific knowledge and skills:

  • Understand the key features and applications of the National Stormwater Calculator.
  • Learn how to input site-specific data to generate accurate runoff estimates.
  • Analyze the impact of land cover, soil type, and drainage on stormwater behavior.
  • Apply Low Impact Development (LID) practices using the calculator’s modeling tools.
  • Incorporate climate change projections to assess long-term stormwater risks.
  • Interpret estimation results for capital and maintenance planning.
  • Compare pre-development, post-development, and LID-optimized scenarios.
  • Use SWC-generated insights to support stormwater management strategies.
  • Gain hands-on experience applying the tool in urban and rural contexts.
