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

San Mateo County Environmental Health Services coordinates the event in partnership with the California Coastal Commission, the Ocean Conservancy, and many Statewide and local partners (see below).

The next event is scheduled for Saturday, September 19th, 2020. Sign up for a reminder email!
