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.

🗺️ 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.
