Site work and new construction of a mixed-use development in Saint Charles, Missouri. Design plans call for the construction of a municipal facility; 600,000-square-foot clubhouse / community center; fitness / recreation center; museum; and restaurant.

St. Charles Proposition C was approved by voters on April 2, 2024, to create a new "City Centre" complex with a new City Hall and other facilities at the former American Car Foundry property. As envisioned by city officials, the project would link the historic Main Street District with the Frenchtown historic district. In addition to a new City Hall, the project will build a Historical Society office, a Senior Center with a recreation center included, offices for Sister Cities International and an arts and cultural center with restaurant incubators. As of September 12, 2024, project is in design phase. The site of the proposed project, the former American Car Foundry, consists of buildings with more than 600,000 square feet along the banks of the Missouri River. The Foundry Art Centre already operates out of the site, which was a former train car factory that operated since the 1870s and closed in 1959 due to lower demand for trains. The arts center opened in 2004. The city center complex would house the city hall, providing extra office space, and an expanded historical society. The complex would include updated fire-suppression systems to promote safety. The city would consolidate services for residents to a single floor, increasing accessibility and convenience. Plans include a separate building that would house the redesigned senior center. The senior center will also feature a rec center component. The city would use the same building to create council chambers separate from city hall for public meetings and events. The complex would feature other community amenities, including an arts and cultural center, daycare and Sister Cities International offices. Mixed-use developments such as apartments and restaurants will complement the area. The city would build the complex at the American Car Foundry property, providing direct connections between the historic main street district and Frenchtown cultural hubs. The complex would include a connected parking garage. Plans include walkways throughout the complex that connect with the nearby Katy Trail.
