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
Explore stormwater solutions tailored to your property, find examples of projects citywide, or select a contractor on the RainWise Tools website (requires high-speed internet connection).
To find out about new Seattle rebates for installing cisterns and rain gardens, see RainWise Rebates.
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.
