The relocation centers were not considered by authorities to be either concentration camps or internment camps but the perception was otherwise. Barbed wire fencing enclosed most of the living area, the guard towers with searchlights and the military police were always visible.

Residential Areas

Plans for facilities at the center included 44 residential blocks however only 35 residential blocks were constructed at Minidoka leaving the remainder empty. Each built block had fifteen, 20' by 100' barracks structures and five service buildings. The service buildings included a 40' by 100' mess hall, a 20' by 50' laundry, two latrines and an ironing room. These buildings were all temporary military-style Theater of Operations (TO) structures of wood frame construction with tar paper covering the outer walls and roof. These buildings were designed to last two years but because of the heat, dry climate, and green lumber, the buildings began to deteriorate early. The buildings were not insulated or properly partitioned for family groups.

Other Facilities

Other facilities at the center included most of the infrastructure that would be required for any town of 10,000. The administrative area included admin buildings, a town hall, a post office, mess hall, a police station, and staff housing. There was a warehouse group & motor pool group. Other groups included a Hospital and orphanage Group, schools, and fire protection. Agricultural facilities included a hog farm and chicken ranch as well as crop fields.
