Description: It is a 10' diameter, 2' deep rain garden planted with native species. It was funded by the WaterWorks grant won by Cascadia College. The garden collects and filters water running off the roof of Truly House, preventing flooding on the lawn and hopefully improving downslope water quality. So far it has been successful at preventing flooding or ponding when heavy rain has fallen. Soil on the site was rocky clay glacial till, which was removed and replaced with bioretention soil mix.



A rain garden is a bowl-shaped garden designed to capture and filter stormwater runoff from roofs, driveways and other hard surfaces, keeping it from becoming harmful water pollution. Rain gardens are relatively simple to install and feature well-draining soil and easy-to-maintain plants that allow for stormwater infiltration. For simplicity we define “Rain gardens” as an inclusive catch-all for simple as well as engineered, small as well as large versions of this concept, including: Bioretention facilities, stormwater planters, Bioswales etc.
