Public reports from the Department of Emergency Management

Shortly after the 2023 New Year, National Weather Service informed Sonoma County of an incoming series of atmospheric rivers forecast to place the Russian River above flood stage. Between January 1 and 19, these storms delivered between 5 and 20 inches in different parts of the Operational Area.

With the gradual wind-down of the COVID-19 pandemic, 2022 proved to be both a year full of promise and some new challenges. The Department of Emergency Management (DEM) was quickly thrust into drought response as the Spring was one of the driest on record. The department also responded to the extreme heat and power outages of September and then just weeks later, the extreme cold weather in December. Just two weeks later— at the very end of December—we saw the first of the dynamic atmospheric rivers that would prove so challenging as 2023 opened.

2021 provided the Department of Emergency Management with a much-needed period of stability for general planning and overall preparedness. Because we were not activated into a full response mode, DEM personnel were able to focus on coordinating and completing projects, maintaining relationships with partners, exercising plans, and working with communities.

In addition to COVID-19 in 2020 California saw its worst year for wildfires in area burned at nearly 4.2 million acres. Sonoma County deployed resources in response to the Walbridge, Glass, and Meyers Fires in the parts of the County.Unseasonably high temperatures coupled with evacuations and Public Safety Power Shutdowns (PSPS) added to the mixture of situations facing Sonoma County leaders and officials to manage. This Assessment Report attempted to capture feedback from participants, review data and documents, and deliver appropriate findings and recommendations.  

Sonoma County activated its EOC on March 1, 2020, to manage the growing pandemic (COVID-19) crisis. The number of cases continued to increase during the year. A substantial number of Sonoma County and cities and town staff members had been involved in managing, supporting, or assisting the response. As the year progressed additional incidents occurred which added to the complexity of the situation.

  • Wildfires After-Action Report - October 2017

    Department of Emergency Management Sonoma County

    The wildfires of October 2017 will be long remembered for their ferocity, speed, and the devastating impact they had on communities in Sonoma County.  Like the majority of jurisdictions in California, Sonoma County had not experienced this magnitude of disaster in living memory.  The scope, scale, and duration of the wildfires pushed the County’s Emergency Operations Center (EOC) facility, systems, and staff well beyond their design limits and experience.  Some 660 EOC staff provided over 33,000 hours of service during 47 days of activation. Many who served had personally lost their homes but all were deeply affected by the suffering and needs of the community.  By looking back, we will be better prepared for the future.
