ST. CHARLES COUNTY, Mo. — The St. Charles County Council unanimously approved a six-month moratorium on new data center development Monday night, pausing any new project approvals while officials study potential impacts. The meeting also included discussion of changes to a senior property tax freeze and local efforts to address dangerous driving. County Executive Steve Ehlmann characterized the measure as a temporary pause, not an outright ban, and said officials will review power, water, noise and public-health implications over the next six months. Residents voiced opposition during the meeting and county leaders plan additional public input and interjurisdictional study before deciding any long-term policy steps.
