EMS Planning: Both single and multi-county local EMS agencies must develop and submit a five-year EMS plan and annual updates to the EMS Authority for a local emergency medical services system according to the state system standards and guidelines. The purpose of the local EMS plans is to meet community EMS needs through the effective utilization of local resources.

Transportation: The Emergency Medical Services (EMS) Act charged the EMS Authority in 1980 with providing oversight of the planning, implementation, and evaluation of local EMS agency (LEMSA) systems. This includes the review of local transportation plans for ground and air providers, and oversight of 308 ambulance zones/areas. Exclusivity of an ambulance zone/area is achieved through a request for proposal or grandfathering via Health and Safety Code, Section 1797.224.
