Chico Army Airfield
Former Chico Army Airfield comprises 1,450.32 acres in Butte County, California, and is located two miles north of the City of Chico,
The Former Chico Army Airfield is now operating as a general aviation airport, Chico Municipal Airport, and a light industrial park. The Site is owned by the City of Chico and other individual property owners in the County of Butte.
The DoD-built improvements included cantonment, warehouse, aircraft and vehicle maintenance facilities, hangars, landing strips, groundwater wells, a sewage treatment plant, and underground fuel tanks. Most of the structures constructed by the U.S. Army have been removed or are currently used for Chico Municipal Airport operations. The government-owned land consisted of 10.97 acres, containing 15 buildings used for civilian war housing. The balance of the land, 1,045.32 acres that were under lease, contained approximately 300 buildings and structures, a 6,700-foot runway, taxiway, airfield facilities, a street system, a water system (subsequently sold to California Water Service Group), an electrical distribution system (subsequently sold to Pacific Gas and Electric Company), a sanitary sewerage system, and a railroad line.
