The former Forest Park Recreation Camp, also referred to as the Forest Park Area of Concern (AOC) was established in 1942 as a recreation camp for soldiers. However, as early as 1917, military demonstrations were held at Forest Park, which included an Army tank demonstration, a military parade and Army troops from Jefferson Barracks performing daily mock World War I (WWI) battles. These activities resulted in the burial of unexploded ordnance (UXO) consisting of WWI-era mortar shells and projectiles in a portion of Forest Park. The Forest Park AOC includes the lower nine holes of the Norman K. Probstein Municipal Golf Course, the Grand Basin and the Art Hill area. The selected response action for the Site, which was implemented in 2004, includes the distribution of education awareness materials, a Memorandum of Agreement (MOA) between the City of St. Louis and the USACE and the passage of city ordinance 68329. The ordinance binds the City of St. Louis to the provisions of the MOA. The response action is intended to promote military munitions awareness and assist in the identification of munitions for construction personnel working in the Forest Park AOC.
