A Guide to Rain Garden Design, Construction and Maintenance
Course Highlights

This engineering online PDH course explains how rain gardens work and describes their eco-friendly benefits.


Rain gardens are shallow, constructed depressions that are planted with deep-rooted native plants and grasses. Conversion of land into impermeable surfaces creates new challenges for storm water runoff. This course provides economical options to the otherwise costly stormwater challenges. This course also provides design and construction information including: FAQs, sizing and siting locations, landscaping, plant selection, catchment zones, slope calculations, designs for various soil types, construction, settling, and cost calculations.


This 5 PDH course is intended for civil engineers, geotechnical engineers, landscape architects and contractors who want to learn the methods to design, construct and maintain rain gardens in various conditions.
Learning Objectives

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