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 and waterways.

Why be RainWise?

Simple practices like planting trees, using compost and mulch, and building rain gardens and cisterns help:

  • Reduce pollution
  • Reduce flooding
  • Protect property

Today, Seattle manages nearly 100 million gallons of polluted runoff each year using green stormwater infrastructure methods. Our goal is to manage 700 million gallons of runoff a year by 2025. Learn ways you can help from the RainWise guide (pdf).
