Cochise County sets new rules for future data centers

Cochise County supervisors in Arizona have approved a new ordinance establishing the county's first local standards for data center development. The proactive measure defines data centers within county code and requires all future projects to obtain special use authorization in designated zoning areas. The ordinance also sets standards for water use, infrastructure, site design, and long-term management. Board Chairman Frank Antenori described the document as "living, breathing," indicating that it will be further refined through public work sessions over the coming year. County officials emphasized that the ordinance does not approve any specific project but instead creates a structured and transparent process for reviewing future proposals. This move was prompted by the rapid growth of data centers across Arizona and the lack of localized evaluation standards. During its creation, the ordinance incorporated significant public input, with many residents expressing concerns regarding water use, power demand, and potential impacts on Cochise County's rural character. Despite these concerns, there was broad support for establishing regulations to ensure careful evaluation of future proposals. The new rules align with the Cochise County Comprehensive Plan 2045, which mandates that high-intensity uses demonstrate adequate infrastructure and water availability. Currently, there are no active data center applications in Cochise County. With this new ordinance, the county is prepared to evaluate any future proposals through a predictable and transparent process that prioritizes public health, safety, and responsible land use.
