Working here

Per-facility headcount is not published here: no reliable public figures exist for these sites, and construction announcements are not permanent employment. Arizona Land Consulting is developing this site rather than operating it, so any long-term operator has not been established here.

Our own notes

These remarks are Arizona AI's own. They say how this record is counted or what we could not find, so there is no outside page to link.

Arizona AI found no announced tenant or operator. An earlier version of this page said the county approved zoning for a data center on a 2,000-acre site in December 2025. County records show the December 2025 decision changed the land use plan, and the rezoning that followed covers about 1,687 acres, so Arizona AI corrected the land figure and this account on October 11, 2026.
