Disaster Communications

Disaster Communications

California’s residents deserve reliable public safety services. The federal, state, and local agencies providing these services require efficient wireless voice and data communications systems to receive the public’s requests for service, to coordinate the delivery of those services, and to communicate life-safety information among responders. A sufficiently robust and secure public safety radio communications voice and data infrastructure supporting federal, state, and local agency communications is critical to California’s future security, health, welfare and vibrancy. California’s size, topography, and diverse land use create unique challenges in designing and providing public safety communications systems to meet the needs of the state’s population in a cost-effective manner.


  • Marin Emergency Radio Authority – A Joint Powers Authority in Marin County formed in 1998 to plan, implement, and manage a countywide public safety and emergency radio system for the use of all 25 member agencies. MERA provides the communication link between 911 public safety dispatch centers and public safety units in the field that respond to emergencies. The MERA radio system gives the dispatch centers the ability to assign single or multiple responders within just seconds of receiving a 911 call, depending on the emergency.
  • AlertMarin – The Marin County Office of Emergency Services is urging local residents to register their cell phones or Voice over Internet Protocol (VoIP) devices to receive emergency alerts sent by phone call, text or email on the County’s upgraded notification service. Such alerts could save the lives of you and your family – and registration only takes about one minute.

    • The upgraded system provides these benefits: 
      • The ability to have up to five locations per contact (such as addresses for home, school, work, children’s schools, elderly parents’ homes, etc.) 
      • Mobile applications to manage contact information and receive notifications 
      • An easy-to-use portal that works with all web browsers
    • Remember: It’s free! Please sign up to receive emergency alerts.
  • State of California – Emergency Digital Information Service – The Emergency Digital Information Service (EDIS) delivers official information about emergencies and disasters to the public and the news media in California.
  • Federal Communications Commission (FCC) – Emergency Alert System – Requires TV and radio broadcasters, cable television systems, wireless cable systems, satellite digital audio radio service providers, direct broadcast satellite service providers, and wireline video service providers to offer to the President the communications capability to address the American public during a national emergency. The system also may be used by state and local authorities to deliver important emergency information such as AMBER (missing children) alerts and emergency weather information targeted to a specific area.
