Report Spills and Water PollutionPSSH_RGB

Stormwater... is the rain and melted snow/ice that falls onto our landscape and flows off of rooftops, streets, bare soils, and all other exposed surfaces. These surfaces can have pollutants on them (such as pet waste, dirt, litter, yard waste, chemicals, and auto fluids like oil and gas to name just a few) that will hitchhike with the stormwater as it travels, and then sadly if the Basic anatomy of a storm drainage systemstormwater is not treated, the pollutants end up in our ponds, creeks, lakes, rivers and eventually Puget Sound.

The City stormwater utility takes care of this runoff after it flows off private and public properties.  Below is a link to describe the City stormwater program and what we do.

See what our City stormwater program does for you! 

Stormwater is part of the water cycle, and as you know everything needs water, and good quality water. Polluted water is not drinkable, it can make us and other animals sick or worse, it smells bad, it looks bad, and we can't use it.

Pollution in stormwater affects... You!

This is why all of us must to do our part to keep pollutants stored, used, and dispose of properly so they don't end up in our water resources and environment.

Check out a 5 minute video What is stormwater and why is it important? by King County that explains stormwater and its effect on the area.

The Drainage Master Plan for the city was adopted in November 2008. It addresses the current and future needs of the stormwater program, projects to reduce flooding on city streets, and repair and replacement of the system.
