Yuma City Council discusses data-center infrastructure and community impacts
The approved April 1 City Council minutes record discussion of data-center power demand, potential utility-rate impacts, broader community effects and possible natural-gas energy infrastructure. They describe an initial seminar for elected officials, with later sessions planned for investor groups and the public, and state that local-government authority over whether a project proceeds rests with City Council unless state preemption changes that. These discussions document infrastructure and policy consideration; they do not by themselves establish data-center recruitment.
