Cotati Police Department holds evacuation drill

September 3, 2021

The Cotati Police Department, Sonoma State University Police Department and the Rohnert Park Department of Public Safety will conduct a joint MOCK evacuation drill using HI-LO siren equipped patrol vehicles.

HI-LO sirens are used by all Sonoma County Law Enforcement Agencies to evacuate citizens for emergencies, including but not limited to fires. HI-LO sirens will only be used for evacuations. 

When you hear the HI-LO it is time to go!

This is only a drill, and we ask that you do not evacuate on this date. You can receive emergency alerts through Nixle by visiting or by texting your zip code to 888777 to start receiving mobile Nixle alerts to your cellular phones.

In a real evacuation, you will receive information from the city through Nixle and other channels giving you information on what and where the threat is so you can evacuate in a safe direction of travel. To view your evacuation zone designation online to
