Project Blue is determined to go ahead on the original site near I-10 and Houghton.
A memo from Pima County Administrator Jan Lesher to the Board of Supervisors says Beale Infrastructure, the company behind the datacenter plan, is redesigning the center to use a combination of air cooling and closed loop liquid coolant to operate the project.
In a letter, Beale contends it has the legal right to go ahead with the purchase of county land even though the City of Tucson refused to annex the property into city limits.
The land sale contract included a condition that the land had to be annexed but Beale says it has the right to waive that requirement.
Protests over high water and electricity use convinced the City of Tucson to refuse to annex and refuse to provide cooling water for the site
