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. Tens of thousands of people across the state come together to help make our communities cleaner and healthier for people and animals.

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. Families are encouraged to bring their children, as this family-friendly event is a great opportunity to learn about litter and how to prevent it from ending up in our local streets and waterways.
