How to Build a Rain Garden

Congratulations for thinking of building a rain garden!

A great first step is to watch this 5 minute video: Building a Rain Garden in the City and learn why, where and how to build a rain garden. A more in-depth instructional video is located on our Stormwater Research & Extension page.

Next, download the free Rain Garden Handbook for Western Washington (pdf). The handbook will help you design, install and maintain your rain garden. Be sure to check out where and where not to build your garden. Not every place is suitable.

Free online Rain Garden Training Program

The Rain Garden Training program is offered through the Washington Stormwater Center and Washington State University Extension. Rain gardens are a useful tool for managing stormwater locally and a requirement for many jurisdictions in the Puget Sound and beyond.
