Emergency Communications Commission

We were created to administer an emergency communication system including an inter-operable, county-wide wireless radio communication network providing communications links that permit participating governmental entities to communicate within the geographic boundaries of the county. This includes the radio system, the emergency alert system, and the enhancements to the 911 system.
