Emergency Public Information


Contra Costa County offers our residents many ways to keep up to date on information in an emergency.

Sign up for notifications from the County by visiting our "Notify Me" category of our website.  Select the topic titled "Contra Costa Ready," and we'll email you updates on topics such as sandbags, dealing with storms and extreme weather, and recovery information in the event of an earthquake or other disaster.

Contra Costa County also maintains a Community Warning System that allows you to register for alerts by email, telephone or text message in the event of a possible threat to your safety.  Sign up for Warning System alerts, and find out about the sirens that are operational in parts of the County.

Many of our offices use social media to connect with residents in both emergencies and non-emergency situations.  Visit our registry of social media sites in the County and follow those that interest you.

The state and federal governments provide a wide range of emergency information as well.
