Local votes and rules
✅ Approved · Maricopa County
County supervisors voted 4-1 to give Project Baccara a special permit needed near Luke Air Force Base. The 160-acre site off Olive Avenue and Litchfield Road would hold two data centers and a gas power plant, about 400 feet from a dozen homes. It still needs an air permit.
✅ Approved
City planning board approved a smaller EdgeCore data center in Eastmark: two buildings (1.2 million square feet, down from 2.1 million). Generator tests only 9 a.m. to 9 p.m. It still needs a city council vote.
📜 Data center rules · Maricopa County
County supervisors updated zoning for data centers on unincorporated land. They are allowed only in the IND-2 and IND-3 industrial zones; other land must be rezoned first.
🗺️ Zoning change · Maricopa County
County supervisors unanimously rezoned about 2,000 acres west of the White Tank Mountains for industrial use. This clears the way for Hassayampa Ranch, a planned data center campus over 1 gigawatt led by Arizona Land Consulting.
📜 Data center rules
City council unanimously passed data center zoning rules, in effect Aug. 8, 2025. Data centers need council approval, may only go in industrial zones, must be 400 feet from homes and no taller than 60 feet, and must do an early review of power and water use.
