What's the Problem?

With every storm, rain carries pollutants off our roofs, driveways and other hard surfaces to local creeks, Lake Washington and the Puget Sound. During big storms, the sheer volume of this “stormwater” can cause sewer overflows, and erode hillsides and stream banks. Rain gardens and cisterns can help control this stormwater with your help.

How to become RainWise

The RainWise program provides rebates that cover most or all of the cost of installing cisterns and rain gardens on your property. To receive a rebate, you must live in an eligible combined sewer overflow basin. The average rebate has been around $4,400.

You can also call the Garden Hotline at 206-633-0224 for eligibility information.
