Do you live in unincorporated Contra Costa County? If you're concerned about flooding at your home or business when the rainy season hits, you can visit one of the sandbag stations located throughout the county. Please note that you'll need to bring a shovel, but bags and sand are available for free.

 If you live within the boundaries of one of our 19 cities, please contact your City for sandbag locations and information about sandbag distribution (PDF).
