Sonoma County evacuation zones work by address

Sonoma County emergency notices work best when you know the address-based zone before you need it. The evacuation zone page gives two useful paths: a zone lookup tool and an interactive incident map.

A fire, storm, flood, road closure, or shelter-in-place notice can be very specific. A town name or rural road name may not be enough. The map can show evacuation status, road closures, and other incident information tied to the zone.

For a household, write down the zone for home, work, school, older relatives, and any place where animals are kept. If you are visiting, look up the lodging address, campground, tasting room area, or trailhead before a red flag or storm day. This is not a reason to worry through every trip. It is a simple way to make official messages easier to understand if something changes.
