Emergency Evacuations

What is the map below? 

The County of Sonoma manages a county-wide evacuation map that is used to help identify areas that are under threat either by fire, flood, earthquake, or power outage. The map found at the bottom of this page includes zones for areas inside Petaluma, as well as areas in other cities and unincorporated County areas. This map will indicate any current evacuation warnings or orders.

Where is your zone?

This map is interactive. You can type your address in the search box in the upper right corner, and it will zoom to your area. Petaluma's zones start with the letters PTL and are followed by numbers. Click here to download a viewable only version of the evacuation map.

How do I use the map?

In the lower right of the map, you will find additional tools. The legend tool will provide you with a description of what each of the symbols on the map represents. Additionally, clicking on any symbol will pop up more detailed information. The Layers tool will allow you to turn on additional layers of information, or turn off layers that are not of interest. There is also a Measurement tool and a Printing tool provided.


If an alert or warning needs to be issued for a potential threat to the City of Petaluma, community members can receive these messages by subscribing to Nixle or SoCo Alerts. As part of our emergency management and preparedness, the City of Petaluma provides this alert and warning service free to our community.

Like the County of Sonoma, the City of Petaluma also has the ability to activate the Wireless Emergency Alert (WEA) system for situations that present an imminent threat to life or property. This notification does not require a subscription and is typically received through a wireless device like a mobile phone or tablet. You may have already seen this type of alert before as it commonly used for AMBER alerts. For more information about WEAs, please see below:

What is WEA?

Wireless Emergency Alerts (WEA) is a nation-wide system providing lifesaving information for the State of California. WEAs are used to send concise, text-like messages in English and Spanish to WEA-capable mobile devices during emergency situations. WEAs are sent by your state and local public safety officials such as the National Weather Service, the National Center for Missing and Exploited Children, and the President of the United States.



Alerts issued by the President or a designee during a national emergency.


Alerts issued when an imminent threat to life or property exists in your area, including severe human-made or natural disasters such as earthquakes, wildfires, hurricanes, and tornadoes.


Alerts issued to help law enforcement search for and locate an abducted child.
