US Cities Move to Regulate AI Data Centers

Municipal governments across the United States are taking legislative action to regulate the growth of artificial intelligence data centers. In Milwaukee, a Common Council committee unanimously approved a proposal to pause new developments and expansions for up to one year. Led by Marina Dimitrijevic, the measure seeks to establish the city's first formal zoning definitions for data centers to address noise, air quality, and energy consumption before a full council vote on October 13.

In Memphis, the City Council voted 7-5 to postpone a decision on a 12-month moratorium until October 20. The delay sparked chaos at City Hall, where roughly 100 protesters occupied the hall, leading to verbal clashes and a physical fight in the lobby. The contested moratorium concerns facilities operated by SpaceXAI, including Colossus and Colossus 2. While Councilman JB Smiley Jr. argued for the pause to address community concerns, Councilman Jeff Warren warned it could drive developers to neighboring counties.

Other cities are acting preemptively despite having no current applications. The Alachua City Commission approved the first reading of a 12-month moratorium following resident concerns over water quality and utility costs. Meanwhile, in Charleston, West Virginia, Council member Emmett Pepper introduced an ordinance to establish guardrails for smaller data centers, focusing on noise regulation and community benefit agreements to help residents lower energy costs.
