Thank you to everyone who came out and participated in Coastal Cleanup 2022 to help protect our bay and ocean from litter pollution. The County is a much cleaner and healthier place today because of all your work.
If you weren’t able to volunteer for Coastal Cleanup 2022, you can still participate in a neighborhood cleanup, or meet with a local organization to pick up litter in San Mateo County year-round.
Thank You Statewide and Local Partners!
