Pima County Project Blue: Rezoning, Development Agreement, and Litigation
Pima County, AZ · Pima County, Ariz., Project Blue rezoning and development agreement (2025); Pima Cnty. Super. Ct. litigation
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.
Technical detail
Pima County Bd. of Supervisors rezoning and land sale (~290 acres) and Dec. 16, 2025 development agreement with Beale Infrastructure; challenged in Pima County Superior Court (open-meeting-law claims dismissed Apr. 13, 2026).
Who is protected: Opponents' protections rest on open-meeting and zoning-process litigation; the county action itself facilitates the project
Who must comply: Beale Infrastructure (agreement terms); Pima County (procedural law)
