Stormwater Calculator: Guide and Application

COURSE NO: C04-073
PDH CREDIT: 4
Stormwater Calculator: Guide and Application
Course Highlights
​This online engineering CPD course offers a comprehensive introduction to managing stormwater, which is crucial for sustainable site development and flood prevention.

This course explores the National Stormwater Calculator (SWC), a powerful web-based tool created by the U.S. Environmental Protection Agency (EPA). It offers a step-by-step guide on how to effectively use the SWC to estimate runoff, retention, and low-impact development (LID) performance for any location across the United States.

In addition, this course focuses on assessing hydrological conditions, incorporating climate projections, and applying LID controls to improve site resilience. It equips professionals such as engineers, planners, and property developers with the tools and strategies needed to make informed, data-driven decisions and enhance the sustainability of their stormwater management projects.

This 4 CPD online course is applicable to civil engineers, environmental consultants, as well as other technical professionals who are engaged in stormwater management, site development, and green infrastructure planning.
Learning Objectives

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

  • Understanding the essential features and uses of the National Stormwater Calculator
  • Learning how to enter site-specific data for accurate runoff estimations
  • Knowing the effects of land cover, soil type, and drainage on stormwater dynamics
  • Familiarizing yourself with the implementation of Low Impact Development (LID) techniques using the calculator’s modeling capabilities
  • Understanding how to integrate climate change projections to evaluate long-term stormwater challenges
  • Learning to analyze estimation outcomes for effective capital and maintenance planning
  • Knowing how to compare scenarios including pre-development, post-development, and LID-optimized conditions
  • Familiarizing yourself with leveraging insights from the SWC to enhance stormwater management strategies
  • Understanding the practical experience gained from using the tool in both urban and rural settings
