Operations Center


Cal OES Headquarters

The Cal OES Headquarters building is nearly triple the size of the former Governor’s Office of Emergency Services cold war-era headquarters. It was dedicated in May of 2001 at a cost of $38 million. The facility is 118,400 square feet and provides the agency with centralized office space and the state-of-the-art State Operations Center. This facility covers 12.5 acres at the former Mather Air Force Base and allows Cal OES to combine its headquarters operations – planning, response, recovery, hazard mitigation, and homeland security – from multiple Sacramento offices into one.
