Local votes and rules
⏸️ Pause on new data centers · Pima County
County supervisors voted 3-2 to pause new data centers in unincorporated Pima County for 120 days, with a possible extension. It covers projects that had not yet applied for permits, so Project Blue and Project Gravel are not affected. The county is writing new zoning rules meanwhile.
🗳️ Public vote
Residents turned in about 2,800 signatures each on two petitions to let voters decide the data center rezoning. The town clerk rejected them because they were missing the right ordinances and land description. Beale sued the town over the petitions. In May 2026 a judge sided with the clerk, so there will be no public vote.
⚖️ Court case · Pima County
The No Desert Data Center Coalition sued Pima County in January 2026, saying the public notice for the Project Blue rezoning hid what it was for, which they said broke the open meeting law. A judge threw out the case on April 13, 2026, ruling the county did not break the law.
🗺️ Zoning change
Town council voted unanimously to rezone two farm parcels on Luckett Road (about 600 acres) for a hyperscale data center by Beale Infrastructure. One member whose family owns a parcel did not vote. The planning commission had recommended it 6-0.
✅ Approved · Pima County
County supervisors approved the rezoning and the sale of county land for Project Blue, a large data center near the Pima County Fairgrounds.
📜 Data center rules
Town council passed Ordinance 2024.029. Very large (hyperscale) data centers need a special rezoning (specific plan), must meet design and noise rules, and must show they have enough power and water.
