The County of Sonoma has released official evacuation zone maps, designed to help residents be ready for any emergency that may require them to evacuate their homes.
In the past, evacuation zones were different for each incident. Now zones will remain the same, and residents are urged to learn their evacuation zones and be ready to go when an evacuation order is issued.
The maps show evacuation zones for the city of Sonoma and all of Sonoma Valley.
It is important to know what zone you reside in ahead of time so that you can quickly evacuate if orders for your zone are ever issued. Find your zone, then write it down, screenshot it, or save it in your memory, so you can reference it and are ready if/when the time comes.
You can find your zone two ways:
Use the Address Lookup Tool and the County’s website, or
Please note that the zones for the City of Sonoma have been updated. The City of Sonoma is divided into four zones or “quadrants.” They are:
Zone SO-A01, which includes all areas in Sonoma city limits that are west of First Street West and north of West Napa Street.
Zone SO-B01, which includes all areas in Sonoma city limits that are east of First S Street West and north of East Napa Street
Zone SO-C01, which includes all areas in Sonoma city limits that are east of Broadway and south of East Napa Street.
Zone SO-D01, which includes all areas in Sonoma city limits that are west of Broadway and south of West Napa Street.
Important Note: These are the City’s current best-laid plans for an efficient evacuation of our community during a large-scale emergency. However, it is important to understand, that depending on conditions and varying hazards, modifications to designated zones could become necessary during an emergency. If changes to the boundaries of a zone were needed during an emergency, rather than issuing an evacuation order for a designated zone, the evacuation order may instead refer to geographic boundaries, streets, or landmarks.
