The record, newest first

  1. Brisbane's corrected notice for the revised project says the plan contains no data center and describes a building of about 895,000 sq ft. Comments ran to Sept. 8; the city's page, in an earlier update, anticipated a Draft EIR in fall 2026. (City of Brisbane (posted by Orchard Partners), Aug. 6, 2026; City of Brisbane, undated)

  2. Orchard Partners announced it had submitted a new plan without the data center, leaving one 892,000-square-foot building for advanced manufacturing. (Orchard Partners, Nov. 5, 2025)

  3. Orchard Partners announced a revised plan with a 180,000-square-foot data center and a second industrial building, about 890,000 sq ft together. (Orchard Partners, July 1, 2025; DatacenterDynamics, July 25, 2025)

  4. Brisbane's Draft EIR for the site described a 1.3 million sq ft warehouse project, not a data center. (CEQAnet (State Clearinghouse), Oct. 7, 2024; City of Brisbane, undated)

Conflicts and open questions

  • Site size is about 153 acres in the city's notice and CEQAnet, and about 144 to 145 acres in developer and press accounts.
  • The size figure is the data center building as proposed in 2025.
  • Opponents raised concerns about endangered butterfly species and other habitat, per DCD; no finding on the merits.
  • The city's page dates the revised submission Nov. 4, 2025; Orchard's release is dated Nov. 5.

The developer removed the data center in November 2025, and the city's August 2026 notice says the project includes none. This status covers the data center only: the rest of the project remains under city review.
Power note
