The Department of Emergency Management is responsible for the mitigation, preparedness, planning, coordination of response, and recovery activities related to county emergencies and disasters.
The department serves as the primary coordination point for emergency management's activities affecting more than one jurisdiction, and the unincorporated areas of the county. The Department of Emergency Management became an independent county department in July 2019.
The County of Sonoma and the City of Petaluma will conduct a targeted emergency alert and warning test on Monday, Feb. 9 in two emergency zones in Petaluma. The exercise will be a test of the Wireless Emergency Alert (WEA) for the emergency zones of PTL-011 in east Petaluma, and PTL-003A in west Petaluma. The alerts will be sent out between 1 and 3 p.m. This is not an evacuation exercise. This will only be a test of the alert and warning system.
