Residential Rainwise Program


Managing Stormwater at Home Rain falling on our roofs, driveways, or compacted soil rushes off quickly to the nearest drain or stream. In big storms, this excess “storm water” can cause sewer backups, or pollute and erode our streams. We can all help reduce runoff and pollution with simple RainWise practices. Why be RainWise? • Reduce flooding • Protect property • Restore our waters, for people and wildlife Learn more with the RainWise guide (PDF) and factsheets at right. For printed copies, call the Garden Hotline at (206) 633-0224, or email help@gardenhotline.org

Note: These factsheets are for voluntary improvements by homeowners that are unlikely to require a permit. Any project that needs a building permit must meet the requirements of Seattle’s building and stormwater codes. Additional design guidance, and code requirements for projects applying for a Stormwater Facility Credit, can be found in the Stormwater Flow Control & Water Quality Treatment Technical Requirements Manual (PDF).
