As a stormwater utility, SWM provides a variety of services for ratepayers to keep people safe and to keep our rivers, lakes, streams, and Puget Sound healthy. Drainage related services are among the most visible in our community, especially during big rainstorms.
Report a drainage problem in your neighborhood or request a drainage investigation.
If you have trouble using the drainage investigation request form contact our Drainage Services Coordinator via email or call 425-388-3464.
