The Alameda County Flood Control & Water Conservation District was created in 1949 when the state legislature passed Act 205 of the California Uncodified Water Code. The act defines the District’s role in providing for the control and conservation of flood and storm waters.

Under Act 205, the District is authorized to protect all waterways, watersheds, harbors, and public highways, as well as lives and property, from damage or destruction caused by flood and storm waters throughout the District. The District is also authorized to prevent water waste and diminished water supply, or exportation of water from the District. It may use conserved water—obtained from drainage, storm, flood, or other means—for beneficial purposes.

Further, Act 205 authorizes the District to sell bonds and to levy and collect taxes and assessments needed to fund its mandate in the District.
