June 10 Planning Commission

The City of St. Louis Planning Commission held a meeting on June 10, 2026, focused primarily on zoning regulations for data centers. The commission discussed extensive public input and staff research on proposed amendments to regulate data centers by size, energy use, and environmental impact. Key procurement-related topics included setting caps on data center size (with a final decision to cap major data centers at 500,000 square feet), renewable energy requirements with phased thresholds, and enforcement challenges due to current city staffing and monitoring limitations. The commission debated amendments addressing public impact agreements, buffer zones, backup generator testing restrictions tied to air quality, and non-conforming use clarifications. Several motions were passed, including adoption of renewable energy thresholds and backup generator testing limits. The commission recommended approval of the zoning text changes to the Board of Aldermen, with some amendments to be further refined. The meeting also acknowledged the need for improved enforcement capacity and ongoing review of regulations.
