Register for a Coastal Cleanup Day Site Here!

Every year, on the third Saturday of September, community members join together at coastal sites throughout San Mateo County to take part in California’s largest volunteer event, Coastal Cleanup Day. The San Mateo County Health System’s Environmental Health Services division, along with dozens of local city and community partners, encourages everyone in San Mateo County to participate in the large scale effort on September 16 from 9 a.m. to noon with one of more than 30 designated cleanup sites.

Proper clothes – comfortable closed-toed shoes and sunscreen or a hat. 3. Supplies – bring your own buckets, gloves and a reusable water bottle. Help reduce our overall footprint during the event! In 2016, more than 4,000 volunteers removed 26,000 pounds of trash and recyclables from San Mateo County’s beaches, lakes, and waterways. Families, friends, coworkers, scout troops, school groups, service clubs, and individuals come together to celebrate and share their appreciation of California's unique and delicate coastline. You'd be surprised what we find along the coast: a TV, shopping cart, boat debris, even a recliner! Whatever you find out there, share it with us by posting to Facebook or Twitter using the hashtag #CCDSMC and tag @SMCHealth while you're at it. This event is coordinated in conjunction with the California Coastal Commission, Ocean Conservancy and many statewide and local partners. Special thanks to our dedicated volunteer site captains for their commitment to helping maintain the safety and health of San Mateo County’s coast. To register at a site near you, visit
