Tucson approves new regulations for large-scale data centers
The Tucson Mayor and City Council have adopted new regulations for large-scale data centers within city limits following a public hearing. These standards include a new public review process, noise codes, and requirements for water usage, energy documentation, building height, and setbacks. The decision was made despite calls from community groups for an outright ban on such facilities.
The Tucson Mayor and City Council voted 6-1 to adopt new regulations for large-scale data centers within city limits, following a lengthy public hearing. The decision comes after dozens of community members, including the "No Desert Data Center Coalition," called for an outright ban on such facilities due to concerns about public health, property values, natural resources, extreme heat, and government surveillance.
Council member Miranda Schubert proposed amendments, which were included, to incorporate one- and two-year reviews of the ordinance and to explore legal avenues for a complete ban. Council member Nikki Lee cast the sole dissenting vote, advocating for more time to consider public feedback. Protesters from the "No Desert Data Center Coalition," formed in opposition to the Project Blue data center approved by Pima County last year, were present at city hall.
The newly adopted code defines large-scale data centers as facilities exceeding 25,000 square feet or using more than 20 megawatts of energy. These facilities will now require permitting through special zoning districts and a new public review process, which mandates extensive notice to neighbors and hearings. The regulations also impose requirements on noise levels, mandate the use of generators and batteries for backup energy, prohibit potable water for cooling in certain cases, and require documentation of energy supply mix and use. Building heights are capped at 50 feet, and facilities must be located at least a half-mile from residential zones, natural areas, and schools.
