Conditional Use - March 19, 2026

The City of St. Louis held a conditional use hearing on March 19, 2026, to consider an application for a conditional use permit for a large-scale data center redevelopment project at 3728-45 Market Street and 3854-58 Market Street. The project involves a 525,000 square foot facility intended to serve as a data center with associated office space, promising significant economic benefits including approximately $484.8 million in tax revenue over 10 years, 1,150 construction jobs, and 200 permanent jobs. The developers committed to environmental considerations such as a closed-loop water system, energy efficiency with a power usage effectiveness rating of 1.35, and no tax abatements. The hearing included extensive public testimony both in support and opposition. Supporters emphasized job creation, tax revenue for public schools and city services, and infrastructure investment. Opponents raised concerns about environmental impacts, increased utility costs, health risks from pollution and noise, lack of transparency regarding the end user, and the project's fit with city zoning and long-term planning. Many speakers urged delaying approval until comprehensive data center regulations are in place. No final decision was made at the hearing; the zoning office will make a recommendation to the Board of Public Service, which will vote on the permit.
