The Flood Control and Water Conservation District covers all of Contra Costa County, including its cities, and owns property throughout the county for the purpose of constructing and maintaining regional flood control basins, channels, and creeks. 

The District was formed in 1951, and has been protecting the communities of Contra Costa County ever since. The District offers regional flood protection, and also provides technical information and education to cities and residents. Its operations are primarily funded through property taxes and developer fees. To learn more about services that the District offers, click here
