The administration of the Dickinson County 911 system is overseen by the emergency management coordinator. Responsibilities include overseeing the 911 telephone system, computer-aided dispatch (CAD) system, the public safety radio system, and the rural addressing system.
As of January 1, 2023, the Emergency Management Commission has assumed the duties of the 911 Service Board as allowed by Iowa Code 29C.9a and 34A.3A.
Our 911 dispatchers work under the authority of the Dickinson County Sheriff's Office.
