Disaster Prep by County

Sign Up for Alerts, Get Training, Find Local Services!

The list below pulls together official emergency-preparedness resources for all nine Bay Area counties, plus every city that publishes its own guidance. This list is a place to find evacuation maps, hazard information, alert systems, and local plans all in one place.

Use it to check the recommendations for where you live, work, or spend time. County pages usually offer broad guidance like alert sign-ups, regional hazard maps, and emergency plans, while city pages often include neighborhood-specific details and links to local training programs and events. 

You’ll also see a handful of regional tools that can help in a fast-moving emergency: live fire-activity maps, real-time traffic maps and road-closures, and power-outage trackers. Taken together, they give a clearer picture of what to expect and how to get ready before the next fire, flood, or quake.

One of the most useful things you can do is sign up for your local emergency alerts. These systems provide advance warning and real-time updates. You’ll find links to the major regional alert networks throughout this list, or you can easily find your county’s alert system here.
