Surface Water Management staff work to protect and restore the physical, chemical and biotic integrity of surface water through the promotion of ecological sound land use practices, reduction and elimination of storm water impacts, the assurance of a high performance level from current and future storm water control systems, and education and outreach opportunities to foster healthy watershed stewardship.

To Report Illicit Discharges Or Spills: If the spill is a direct hazard to human or environmental health, dial 911.  Otherwise, contact the Public Works Department at 425.806.6750 (during the day you will be routed to our Surface Water Division and after hours you will be transferred to the Police Department non-emergency number).  
Thank you for being a part of our efforts to protect our ground and surface water.
