Office of Emergency Management
During disasters or large scale incidents the Butte County OEM coordinates the overall response through the Emergency Operations Center (EOC). When activated, the EOC provides a central location for responding and supporting agencies to collaborate response and recovery efforts in order to effectively and efficiently provide information and deploy resources. In non disaster times the Butte County OEM supports and coordinates disaster planning, community preparedness, mitigation, and training.
