Exclusive Operating Area Compliance Data
Sonoma County has two ambulance service areas that are designated as Exclusive Operating Areas or "EOAs" as defined by California Health and Safety Code section 1797.224. Within those areas the service providers operate under exclusive contracts with the County of Sonoma. Exclusive contracts set expectations for response time perfomance. Response time compliance data is a summary of how compliant the contractor is with the contract’s terms and conditions for response time performance. The EOA agreement requires the ambulance arrive within a specified time (or have met some other qualifying compliance metric) at least 90% of the time in each of the compliance zones that make up the EOA.

EOA-1: Sonoma County Fire District (an independent district) and its subcontractor Medic Ambulance are the exclusive emergency ground ambulance transport providers. EOA-1 includes the entirety of the cities of Santa Rosa, Rohnert Park, Sebastopol and Cotati as well as some adjacent unincoprorated communities of Sonoma County.

July 2024-June 2025 EOA-2 Compliance Report
Response time standards are an important ambulance performance measure, but not the only relevant (or important) measure. Over the next year, the County will continue to work with our EOA providers to implement clinical performance and quality of care measurements.
Local EMS Agency and EMS System Assessment Reports
Reports are periodically completed by outside experts after assessing the EMS Agency and/or the EMS system as a whole. These reports help the Sonoma County Department of Health Services (which operates the LEMSA) understand Agency and system perfomance, identify challenges and successes, and become better informed regarding improvement actions.These reports may be informative for EMS system stakeholders and participants as well.
Cardiac Arrest Registry for Enhanced Survival
CVEMSA hosts the office of the statewide CARES Coordinator for California. CARES is a repository of data collected in a regimented format allowing for comparative analysis of EMS system performance. CARES is a nationwide project that allows local EMS systems and states to compare local results to other jusristictions over time.
