The State of California Emergency Plan defines the emergency management system used for all emergencies in California. It describes the California Emergency Organization which provides the Governor access to public and private resources within the State in times of emergency. This report is the first major revision of the State’s Emergency Plan since 1989. The revision reflected changes in the structure and function of California governmental agencies. It included changes in roles, responsibilities, and the addition of new departments, as well as reflecting Federal Government agency roles that have changed. The plan reflects recent advances in emergency management capabilities and changes in the Emergency Services Act (ESA), addressing mitigation, preparedness, response, and recovery activities. There are four parts to the State Emergency Plan. Part One, the basic plan, describes the hazards faced in California, the emergency management organization, the Standardized Emergency Management System, emergency declarations, roles and responsibilities, and administrative practices. Part Two consists of an overview of the organization for response and recovery operations. Part Three is a listing of supporting plans and documents that are identified as references to the State Plan. Lastly, Part Four contains a glossary of acronyms and definitions used in the plan. The State Emergency Plan is intended to be used in conjunction with city, county, operational area (OA), and State agency plans and associated standard operating procedures.
