St. Charles Bans Data Centers as Environmental and Urban Concerns Grow

St. Louis is emerging as a focal point in regional conflicts over digital infrastructure as municipal leaders weigh zoning changes in response to rapid energy growth. The city currently counts 13 sites classified as data centers, which are tucked into neighborhoods spanning Covenant Blu Grand Center, Midtown, Downtown, and Downtown West.

These facilities vary widely in scale, occupying spaces that include a former church and a former newspaper headquarters. The largest recorded facility spans 546,000 square feet, which is roughly one-third the size of a controversial $1 billion proposal recently withdrawn in nearby St. Charles. That St. Charles project triggered widespread resident opposition and led the city council to approve a one-year moratorium on data center applications, making it the first U.S. city to enact such a ban.

Data center growth has tripled over the past decade, according to Department of Energy figures. Federal projections indicate that consumption could double or triple again within the next four years, driven largely by the power demands of artificial intelligence. By 2028, federal estimates show these facilities will consume between 6 and 12 percent of total U.S. electricity.

Local developments continue to draw mixed reactions from municipal officials and community members. One year ago, St. Louis Mayor Tishaura Jones and Greater St. Louis Inc. heralded a $150 million TierPoint data center project planned for Downtown West. At the time, Mayor Jones issued a statement noting that the investment served as a strong vote of confidence in the city’s future.

Critics, however, point to heavy energy and water consumption alongside noise issues. Some nearby residents report a dull aural hum that causes headaches, vertigo, and nausea. Concerns have also been raised that large facilities featuring minimal on-site employment do little to activate streetscapes in dense urban environments.

Zoning Overhaul and Future Oversight in St. Louis

Although St. Louis does not currently feature a dedicated zoning classification for data centers, city hall officials indicate that policy could shift. Casey Millburg, chief of staff to Mayor Jones, stated that the issue is top of mind as officials advance a zoning code overhaul known as ZOUP to build a modern code for a modern moment.

Millburg noted that surrounding community debates and massive proposed developments have sparked significant local conversation. Absent a formal moratorium, St. Louis may need to address these land-use questions directly. Local reporting indicates that developer Green Street has explored plans for a $600 million data center adjacent to its shuttered Armory project, though the firm has not publicly confirmed the proposal.
