Winter Storm Preparedness

Protect Homes and Property

By Supervisor Karen Mitchoff, Contra Costa County, District IV

Late November, I participated in a press conference with Contra Costa County Public Works and Flood Control staff. This was an opportunity to inform the community about current projects the county is working on as well as share details on how people can protect their homes and property during the rainy season.
Public Works crews are still managing repairs and the aftermath of torrential rains that caused so much damage throughout the East Bay earlier this year. Last winter, large storms led to a landslide on Morgan Territory Road that ultimately caused the county to close the roadway. A temporary access was developed, the slide was repaired, and the roadway was reopened in November.
We encourage residents to prepare their property. Determine where you may have excess water on your property and obtain sandbags if needed. Clean your gutters and ditches now to ensure water can flow with no obstructions. Also, look at drainage inlets in the roadway in front of your property. We ask that residents take a proactive approach in keeping the inlets open and flowing if it is safe. County staff will clean these but cannot be at every inlet during a storm. Please assist by cleaning off leaves and trash that block the flow of storm water entering the inlets. 
The county has six sandbag filling stations that are accessible to residents 24 hours a day, seven days a week. All cities within the county also have sandbag locations. Locations for these sandbag stations can be found on our website at Please note that you will need to bring a shovel but bags and sand are available for free. You can find additional information at our Flood Control District’s website: There is a video that demonstrates how to properly fill a sandbag. One big mistake we see is people filling bags completely, thinking more is better. It is best to fill sandbags 1/3 full, which is about three shovels worth of sand.
Information regarding winter preparedness, rain and stream gauges, and flood forecasting is also available on Flood Control's website. Rainfall and stream flow information can be found at and the award-winning “Flood Forecasting Tool” and video at
Our crews can respond to emergencies day and night. If you have flooding concerns, see a downed tree blocking a road or other emergency, please contact our maintenance division at (925) 313-7000.
