The U.S. Army Corps of Engineers, St. Louis District, will begin the demolition of six homes in the Cades Cove neighborhood of Florissant, starting Feb. 9, 2026. This demolition is a critical step in ongoing efforts to remediate legacy contamination from the early atomic energy program and to protect the health and safety of the community.
The homes, located along Coldwater Creek, were identified as being within areas affected by historical contamination. The USACE Formerly Utilized Sites Remedial Action Program is responsible for the cleanup of the contamination within the St. Louis Airport Sites Vicinity Properties. Demolition of these structures is necessary to safely reach and remove contaminated soils beneath the foundations.
