Clean Creeks and Flood Protection Initiative

Our stormwater drainage system is a service that benefits the entire community. Unlike the sanitary sewer system, stormwater does not have a dedicated funding source. With so many infrastructure needs, there is not enough funding to maintain and upgrade the our storm drainage system.  

 Staff will be conducting a community opinion survey in fall 2021 to inform the City’s direction on funding for this initiative.

Preventing Stormwater Pollution

Stormwater Drainage SystemStormwater Pollution Graphic July 2020

Stormwater runoff and other sources of "outdoor drainage" typically flow into street drains each connected to the nearest creek or watercourse. Stormwater does not receive treatment to remove substances that might be harmful to aquatic insects, fish, and wildlife.

Our storm drainage system is comprised of:

  • 130 miles of storm drains
  • 20 miles of open creeks and drainage channels
  • One flood control lagoon
  • Nine pump stations
  • Three-mile Bayfront levee

Quick Facts

We are required by law to prevent contamination of stormwater by utilizing clean work practices, inspecting businesses and construction activities, and educating the public. We are a member of a comprehensive countywide effort to prevent stormwater pollution. For more information, visit San Mateo Countywide Water Pollution Prevention Program.
