The city of Little Rock, Arkansas approved a new data center ordinance following review of incoming development proposals, according to the Arkansas Advocate. The ordinance establishes formal standards for data center operations within the city's limits, building on a regulatory trend spreading across U.S. municipalities. Little Rock joins a growing list of cities, including Allentown and Howard County, that have moved this week to codify data center rules. The ordinance's specific noise, water, and power provisions will shape where operators can site future facilities in the region.
