The Sonoma County Operational Area Emergency Operations Center (EOC) was constructed in 1974 and was remodeled in 2004. On a daily basis the building is used as a computer training center and in emergency conditions is converted into a full operating EOC.

The EOC is well equipped with a Local Area computer network, wireless local area network, telephones, dedicated multiple fax lines, four televisions, and numerous communication systems including an EAS transmitter for generating local emergency alerts. Auxiliary Communications Service (ACS) operators are located in the Auxiliary Communications Center linking the county EOC to public safety and amateur bands. A twelve-line Public Information Hotline is located adjacent to the Public Information Officer's office. A modular status board system is in place allowing information to be posted in each area.

The staffing pattern is Standardized Emergency Management System (SEMS)-based and operational periods are determined during the initial stages of an event. The CAO (or other designated staff) serves as the EOC Director with additional staffing provided by County Department heads, managers and other designated personnel, and other supporting agencies including California Department of Forestry (CDF), California Highway Patrol (CHP), California National Guard (CNG), Governor's Office of Emergency Services (OES), PG&E, and American Red Cross. During an emergency event up to 75 individuals may staff the EOC.
