The record, newest first
KJZZ said it is unclear whether the county's draft data center code would apply to the project. (KJZZ, Oct. 9, 2026)
Pima County's 120-day data center moratorium exempted Project Gravel because it had already submitted permits. (KJZZ, Sept. 23, 2026)
Conflicts and open questions
- The developer is described only as a Pima County landowner; no power figure or exact site has been published. Kept on the 160-acre size (over 100 acres). Coordinates are at town level.
- A separate 200-acre Rancho Sahuarita parcel was pitched for data center use in 2025 (Green Valley News, not opened in this check); any link to Project Gravel is not established.
