Pima County's role in Project Blue is an approval, not a restriction: after Tucson rejected the project in August 2025, the county board voted 3–2 to rezone and sell roughly 290 acres of county land, and on December 16, 2025 approved a development agreement with Beale Infrastructure to move the data center forward in unincorporated Pima County. Opponents sued under Arizona's open meeting law; a judge dismissed that suit in April 2026, with additional litigation filed in January 2026.
Who is protected: Opponents' protections rest on open-meeting and zoning-process litigation; the county action itself facilitates the project
