Detailed entries
Pima County
- Type: County
- Status: 🟢 Active
- Date enacted: 2026-08-11 (Board of Supervisors adopted an addendum-item resolution at its regular meeting, 3-2 vote)
- Normalized date:
2026-08-11(exact) - Duration: 120 days from adoption (2026-08-11 to approximately 2026-12-09), to give county staff time to finalize a zoning code text amendment establishing data-center-specific regulations; Supervisor Heinz's floor amendment provided the moratorium could return to the board for possible extension before the 120-day limit.
- Current end date:
— - Sectors: data center
- Moratorium ID:
az-pima-county-2026 - Legal basis: Resolution adopted by the Pima County Board of Supervisors at its August 11, 2026 regular meeting, added as an addendum item at the request of Board Chair Jennifer Allen (District 3); no separately reported resolution number located in captured sources.
- What prompted it: Pima County Development Services was already drafting a data-center zoning code text amendment (process initiated by a September 2025 BOS vote) when a second, undisclosed data-center project ('Project Gravel,' an 8-building, 160-acre facility near Sahuarita) surfaced via a public-records request; the moratorium bars new data center permit applications while the code amendment is finalized, and (as amended) applies to facilities that have not yet submitted a permit application, so it does not affect the previously permitted 'Project Blue' facility.
- Affected projects: 'Project Gravel,' an undisclosed, 8-building/160-acre data center proposal on land known as Kerley Industrial Park, west of Sahuarita town limits; county officials confirmed the moratorium (as amended to cover unsubmitted permits) would affect this project but not the previously permitted 'Project Blue' data center near the Pima County Fairgrounds.
- Detailed status: Active as of 2026-09-23. 120-day moratorium on the acceptance/issuance of new data center permits in unincorporated Pima County, adopted 3-2 (Supervisors Christy and Scott dissenting) on 2026-08-11 and running to approximately 2026-12-09, while Development Services finalizes a zoning code text amendment. The department is seeking public comment (online survey; a September 28, 2026 open house; proposed rules going to the Planning and Zoning Commission on October 28, 2026) on a related, permanent zoning code amendment that would define data centers (facilities using more than 20 MW), require closed-loop cooling, and set review/design standards; that permanent amendment is expected in December 2026, around when the moratorium runs out.
- Outcome: Board of Supervisors adopted a 120-day moratorium on new data center permit applications in unincorporated Pima County while the county finalizes a data-center zoning code amendment.
