The Flood Control Engineering Division pays for maintenance of its facilities from a variety of sources. These funding sources are separate from the Unincorporated Contra Costa County (County) drainage and road drainage funds.
In general, the Contra Costa County Flood Control & Water Conservation District (FC District) maintains FC District channels, some creek sections, and detention basins. The physical limits of the maintenance that the FC District performs is being clarified by the development of maintenance maps. These maps are currently being reviewed and show the parts of the drainage system that the FC District maintains and what level it will maintain the system or creeks.
The County Public Works Maintenance crews perform the maintenance for the FC District.
