Concord maintains a 24-hour sandbagging station at its Corporation Yard, located at 1455 Gasoline Alley, and sandbags are available and free to Concord residents. Tools and bags are provided. They are available 24/7 during the months of October through April. Updated information is provided through the Concord Sandbag Hotline: (925) 671-3383.

Residents who are unable to fill their own sandbags, such as seniors and persons with disabilities, can make arrangements by emailing Concord Public Works at  

Additional instructions on how to fill a sandbag and how to create a sandbag barrier can be found below.
