The record, newest first

  1. East Valley activists continued to oppose the campus at council meetings; the city said NTT was seeking minor modifications. (ABC15 Arizona, Aug. 14, 2026)

  2. Mesa's planning board unanimously recommended NTT's rezoning, council use permit and site plan change for a seven-building, 2.2 million sq ft campus. (Phoenix Business Journal (via KTAR), May 17, 2026; The Copper Courier, June 9, 2026)

  3. NTT bought the roughly 173-acre site for about $300 million; reports cited up to 360 MW and a first building targeted for November 2028. (ConstructConnect, April 1, 2025; DatacenterDynamics, March 2025)

  4. Mesa City Council unanimously approved the Pacific Proving Technology Campus: seven data halls of about 1.7 million sq ft plus a warehouse and office building. (DatacenterDynamics, Aug. 2024; ABC15 / Phoenix Business Journal, Sept. 3, 2024)

Conflicts and open questions

  • Copper Courier reports NTT applied Aug. 4, 2025, before Mesa's stricter data center ordinance took effect, so the project is grandfathered.
  • Square footage reported as about 1.7 million sq ft of data halls in the 2024 approval and 2.2 million sq ft in the 2026 revised plan (PBJ, Copper Courier).
  • Distinct from NTT's operating Elliot Road campus (ntt-mesa).
  • The commercial lead bundled these NTT buildings with Amazon's nearby Pecos Road site; they are separate campuses.

The full record

Status note
Mesa council approved the original Pacific Proving campus in Aug. 2024. NTT's revised application (rezoning, council use permit, site plan change) won a unanimous Planning and Zoning recommendation on May 13, 2026. Council introduction set for June 8, 2026 was postponed, and in August 2026 the city said NTT was seeking minor modifications. I found no council vote on the revised plan as of Nov. 1, 2026. Residents oppose it.
Power note
360 MW reported for the campus as approved in 2024 (DCD) and at the 2025 land purchase (DCD, ConstructConnect). No figure given for the 2026 revised plan.
