In 2012, after five years of negotiations with the Army, the City of Forest Park purchased 1,170 acres comprising most of the former Fort Gillem for $30 million, and ownership was transferred to the Forest Park/Fort Gillem Implementation Local Redevelopment Authority (ILRA). City officials wanted mixed-use development on the property, but following the housing crash turned their focus to industrial, manufacturing, warehouse and business park development. The only private residences are a 125-unit development owned by The Park, which has a lease with the Army until 2025. There are around 165 acres of contaminated groundwater on the site the cleanup of which the Army is responsible for. The clean up of the land was expected to take ten years.
