Streets and Stormwater

The Street Division and Stormwater Programs protect public and private property by providing safe and well-maintained street surfaces and effective drainage for surface water runoff. The goal of the Foster City Stormwater Program is to ensure we are meeting the stormwater requirements under the National Pollutant Discharge Elimination System (NPDES) permit and to maintain the storm drainage system. Some of the services provided under this program include cleaning stormwater inlets and stormwater maintenance and repair. Protecting our storm drainage system helps keep the San Francisco Bay Area’s Creeks and Watersheds clean. For more information, please visit:
