About the District

The State Legislature formed the San Joaquin County Flood Control and Water Conservation District (District) in 1956 to construct, operate and plan flood control, water supply, drainage, and groundwater recharge projects. The District, a dependent special district, is a countywide entity with the San Joaquin County Board of Supervisors serving as the governing Board of the District. The Director of Public Works is designated as the Flood Control Engineer in the District’s enabling legislation and is delegated additional authority as described in the San Joaquin County Ordinance Code. The San Joaquin County Department of Public Works Water Resources Division (PW Water Resources) staffs the District. A portion of the countywide property tax supports the District’s programs and activities.

The District is statutorily authorized to form zones within the County to fund construction of projects and investigations related to flood control and water resources. Currently, Water Investigation Zone 2, Flood Control Zones 9, and 10 are active zones within the District. Program revenues, expenditures and budgeted activities for each of these specific funding sources are indicated within each of the District budgets and are approved by the Board of Supervisors following a Public Hearing held in June each year.

The District is also an active member agency of the San Joaquin County Area Flood Control Agency (SJAFCA) and Mokelumne River Water and Power Authority (MRWPA).
