In 1946, many buildings, facilities and the land was sold as war surplus. Officers quarters later became the retirement community of Lanark Village. Live munitions had been used in exercises, as well as dummies. In 2001, a U.S. Army Corps of Engineers found that specially trained technicians were needed to clear certain areas that had been sold into private hands.[4]
