Coastal and Bay Cleanup Day

General information

Coastal Cleanup Day (CCD) is an annual waterway and land cleanup held on the third Saturday of September. It’s California’s largest volunteer event and brings community awareness to cleaning up and protecting our marine environment.

San Mateo County coordinates CCD in conjunction with the California Coastal Commission, Ocean Conservancy, and many statewide and local partners (see below).

Cleanups are held all over San Mateo County at beaches, creeks, waterways, parks and neighborhoods and they’re family-friendly events!
