Bayfront Cleanup


The 2023 Bayfront Cleanup has been moved to Saturday, Sept. 23 to align with the Statewide and County events, as well as in recognition of Rosh Hashanah. The event will take place at Seal Point Park. 

Saving Our Bay One Cigarette, One Bottle Cap, One Food Wrapper at a Time

In 2022 more than 630 volunteers collected 14 cubic yards of waste and 8 gallons of cigarette butts were collected from our shoreline, lagoon, and San Mateo Creek. We are hoping for even more volunteers in 2023!

The highlight of the event each year is the "Catch of the Day" where volunteers get to show off their most "unusual" finds.
