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. Please explore our website to learn more about the services that the District offers.


The Flood Control District works to reduce flood risk, promote stormwater quality and restore and enhance natural resource in an environmentally sensitive manner for the communities throughout Contra Costa County.


We proactively work with communities, agencies, regulators, and other stakeholders to:

Provide for safety through flood control protection facilities and programs.

Improve our environment by sustaining and enhancing water quality in our watersheds.

Market and deliver high quality services.

Establish trust by being accountable for our actions and honoring our commitments.

Establish and maintain a mutual understanding of each other's interest.

Increase public awareness and understanding of Flood Control and Clean Water Programs.

Allocate our resources based on a planned program of improvement.

Update our plans and programs to balance the needs of all stakeholders.


We have adopted the values of the Contra Costa County Public Works Department.
