Project Cumulus was a proposed hyperscale data center on about 440 acres along Highway 370 in north St. Charles, near the city's Elm Point well field. The developer, CRG Cumulus LLC, affiliated with Clayco, withdrew the application in August 2025 amid resident opposition. The city then adopted a one-year moratorium and in May 2026 voted 7-1 to amend its code in a way that effectively bans data centers.
