Surface Water Management
What We Do
Surface Water staff work to protect our local streams through storm system inspection, maintenance, construction oversight, stream monitoring, and education and outreach opportunities to foster healthy watershed stewardship. Learn how you can help.
The City’s public storm drainage system consists of 148 miles of pipes, 8,548 catch basins, 1,394 ditches/swales, and 408 detention/retention facilities that include ponds, underground vaults, pervious pavement, and other water quality features. We work in conjunction with our Storm Operations staff to maintain this infrastructure.
Report a Spill
Call 425-806-6750, day or night, to report spills right away. We want to know if you see a spill so we can try to contain it before any pollution reaches storm drains or affects local streams. Learn about what to report.
Report a Drainage Issue
Submit an online form to tell us about your drainage concern, or call 425-488-0118 during business hours. If it's an emergency, call 911.
If your business requires and inspection as part of our Source Control Program, learn about the program and best practices for preventing stormwater pollution at your business.
Whether we’re learning about streams, sustainability, stewardship, stormwater, soil, or septic systems, we invite you to participate!
Learn about our public education programs that are focused on changing behaviors that create stormwater pollution if not done safely.
Help prevent localized flooding during the rainy season by keeping the storm drains near your home free of leaves, trash, and debris.
Preventing Stormwater Pollution
By making small changes in your daily habits, you can have a major impact on the health of local streams, rivers, wetlands, wildlife, pets, and people.
Your voice matters! Your feedback is essential in helping us plan and improve surface water programs and projects within the community.
The Pacific Northwest is home to a number of salmon species. Learn all about them, as well as how to help protect them for a healthier ecosystem.
Spills and Drainage
See pollution near a storm drain? Is a drainage issue affecting your property? Let us know right away so we can check out the problem.
Our two Surface Water Inspectors conduct annual inspections for public and private stormwater systems to make sure they’re functioning as designed.
Stormwater Program Documents
This page contains the documents we provide to Ecology annually as part of the City’s current NPDES Western Washington Phase II Municipal Stormwater Permit.
Stormwater issues can sound very technical, but we’re working regionally to try to make the language and concepts easier to understand.
Water Quality Monitoring
Monitoring helps us identify stream health and trends in water quality over time, and it alerts us to take action when we find high levels of pollution.
Check out some fun, simple science experiments to help demonstrate how a watershed works, learn about permeable vs. impervious surfaces, and much more!
