The San Mateo County Flood Control District is a Countywide Special District that was created by State legislation in order to provide a mechanism to finance flood control projects. The legislation requires that a flood control zone be formed over an entire watershed and a proposed funding source be determined before a flood control project is undertaken. Recent changes in the State Constitution require an election if a flood control zone is to be financed with property assessments or taxes. The Colma Creek Flood Control Zone was created in 1964 to construct flood control facilities in Colma Creek to alleviate flooding in the City of South San Francisco. Originally the project extended from Mission Road in South San Francisco approximately three miles to San Francisco Bay.
