Rain Garden GuideA new guide on building sunken-bed rain gardens to collect and filter runoff water can help Northwest homeowners learn how to redesign home landscapes to help protect rivers and streams.

Rain gardens can help restore the natural water cycle, according to Rob Emanuel and Derek Godwin of Oregon Sea Grant Extension at Oregon State University.

“As our landscapes became developed, rain falling on hard surfaces was directed to pipes, ditches and storm drains that route to streams or into stormwater sewer systems,” Emanuel said. “The result is too much water arriving in a short amount of time and carrying pollutants.”

Rain gardens work like a native forest, meadow or prairie.

“They capture and redirect stormwater from hard surfaces such as roof tops, driveways, parking lots and streets,” Godwin said. “Rain gardens help keep watersheds healthy by filtering out toxins before they pollute streams and lakes, and they can actually recharge aquifers by encouraging water to soak into the ground.”

The new 44-page illustrated guide, “Oregon Rain Garden Guide: Landscaping for Clean Water and Healthy Streams,” was written by Emanuel, Godwin and Candace Stoughton, who works for the East Multnomah Soil and Water Conservation District.
