Originally, it was primarily made up of large residential lots. The community first incorporated in 1950 as a village. The incorporation and establishment of a combination Public Safety Department providing three firefighters and one police officer on duty was to provide lower fire insurance rates for residents. The Village changed to city status in 1974 in an effort to increase property taxes. The maximum “Village” tax rate could no longer sustain the modest city government. In 1983 annexation of a large area to the west more than doubled the size of the city. This caused the city to maintain a police department and contract fire and EMS service to a neighboring fire district.
