Storm Drain MarkingDid you know runoff from the storm drain system is not treated before it reaches our creeks, lakes, and wetlands?

When it rains, water runoff collects oil, pet waste, grease, soaps, and sediment. Where it then enters into the storm drain system, polluting the surface water and the environment.

You or your organization can help raise public awareness, protect our water quality, and reduce the amount of pollution by participating as a volunteer in our storm drain marking program. This activity normally takes place during spring and summer. You can spend as much time as you wish and choose the area you want to mark. Please notify the City at least one week in advance of starting your project. For group volunteers, you must be at least 10 years old and be supervised by one or more adults.  

Instructions, maps, and storm drain marking supplies will be provided. For more information, please contact the city's Public Works Department at (425) 413-8800.
