Design and Construction of residential Rain Gardens

D. Allen Hughes, PE

Rain gardens are shallow, constructed depressions that are planted with deep-rooted native plants and grasses. While rain water has been collected in gardens since ancient times, the concept of the residential rain garden is a recent idea. Conversion of land into impermeable surfaces creates new challenges for storm water runoff. This course provides an explanation of how rain gardens work and their eco-friendly benefits. Course participants will learn to calculate catchment zones, design for various soil types, and calculate slope adjustments. This course provides economical options to the otherwise costly stormwater challenges. The course provides information for design and construction including: FAQs, sizing and siting locations, landscaping, plant selection, catchment zones, slope calculations, designs for various soil types, construction, settling, and cost calculations.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
