Stormwater

Stormwater Coordinator - Ann Gillespie

Stormwater pollution is caused when stormwater runs off of streets, parking lots, sidewalks, or disturbed areas and picks up pollutants such as sediment, oils, or chemicals. These pollutants are transported into the storm sewer system and directly into our lakes, streams, and the ocean.

Learn how you can help prevent stormwater pollution by visiting the Prevent Stormwater Pollution Poster.

Most people are surprised to learn that stormwater is a leading cause of water pollution across the nation. Most stormwater is NOT treated before it enters the creeks or ocean; whatever material the water collects as it runs off the streets, parking lots, your property, or construction site, and ends up in the creek or ocean.

The U.S. Environmental Protection Agency requires that the County implement a Stormwater Management Program (Stormwater Program). Locally, the Central Coast Regional Water Quality Control Board (Central Coast Water Board) oversees the County’s Stormwater Program that details how the County is protecting the water quality of the creeks and ocean from polluted stormwater runoff.
