Colma Creek Flood Zone

The Colma Creek Flood Zone encompasses the area that drains to Colma Creek, made up of parts of the Town of Colma, cities of Daly City, Pacifica, San Bruno, South San Francisco, and unincorporated County of San Mateo. The Colma Creek Flood Zone is one of the four long-standing active flood zones that OneShoreline inherited from the former San Mateo County Flood Control District.

Along Colma Creek, an assessment of future priorities is being completed in close coordination with the City of South San Francisco’s planning efforts. The District has met with City of South San Francisco (City) planning staff and consultants to discuss opportunities to improve Colma Creek in concert with the City’s update to its General Plan, which was completed in 2022. These discussions are focused on flood-prone sites adjacent to the Creek or within Creek right-of-way where either the City or District has land rights, where the City has interest or proposed land use changes, and/or where new private developments are proposed. The District’s goal is to identify sites of interest that will increase the region’s resilience to long-term sea level rise and help transform Colma Creek into an environmental and recreational asset to the surrounding community.
