Stormwater Calculator: Guide and Application

This online engineering PDH 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 PDH 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.
This PE 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
In this professional engineering CEU course, you need to review the course document titled, “Stormwater Calculator: Guide and Application”, which is based on the U.S. Environmental Protection Agency, Publication No. EPA 600/C-22/150, “NATIONAL STORMWATER CALCULATOR WEB APP USER’S GUIDE – VERSION 3.4.0”.
Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty (20) questions to earn 4 PDH credits. The quiz will be based on the entire document.
Upon successful completion of the quiz, print your Certificate of Completion instantly. (Note: if you are paying by check or money order, you will be able to print it after we receive your payment.) For your convenience, we will also email it to you. Please note that you can log in to your account at any time to access and print your Certificate of Completion.
