Storm Preparedness


Concord maintains a 24-hour sandbagging station at its Corporation Yard, located at 1455 Gasoline Alley, and sandbags are free to Concord residents. Residents who are unable to fill their own, such as seniors and persons with disabilities, can make arrangements to pick up pre-filled bags by calling (925) 671-3448. 

Reports of serious flooding, blocked roadways, and/or trees down can be made directly to Police Dispatch by either calling (925) 671-3333 or 911.

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

Remember to stay away from the low-water areas, creeks, and floodplains; and be aware that high winds and saturated grounds can combine to cause trees and branches to fail suddenly.  

When out and about (walking or driving) be aware of your surroundings and stay clear of trees during the storm. You can report trees blocking travel lanes by calling Police Dispatch at (925) 671-3333 or 911.

Please stay away from downed power lines. Always assume they are energized and dangerous. Report downed lines to 911. 

Report potholes using the City's Concord Connect app.


With heavy rain and strong winds in the forecast, it is possible that Concord could experience a power outage. Residents are encouraged to make sure electronic devices are charged up in the event of an outage. Outage information will be available for viewing on PG&E's outage map. In addition, there are emergency preparedness safety tips available through PG&E's Safety Action Center.


Driving through a flooded area puts your vehicle at risk for stalling out and becoming stuck in the water, so please do not drive through standing water.  

If you are driving and you hit standing water and begin to hydroplane, immediately take your foot off of the gas pedal and let your vehicle slow until you regain control. When driving in heavy storm conditions, give yourself plenty of extra time to get to your destination and maintain a safe distance between yourself and the vehicle in front of you. If your windshield wipers are on, your headlights MUST be on as well.
