- September 5, 2026ProposedWalla Walla County's own project page and local reporting show the campus is still in permitting, not construction. The county held a pre-application meeting on April 29, 2026, issued a Notice of Incomplete Application on June 23, 2026, and issued a Notice of Complete Application on August 24, 2026 (files SDP26-01 and SEPA26-05). As of September 1, 2026 no final land-use decision has been made and construction has not been initiated. The record's current 'under_construction' status is not supported by these sources.

How the community has taken it

Port of Walla Walla commissioners approved the amended land sale unanimously (Feb 12, 2026), calling the project transformative; documented concerns from the Confederated Tribes of the Umatilla Indian Reservation (sacred Snake/Columbia confluence), environmental and academic voices, and a commissioner over water and power. No litigation or moratorium; a SEPA environmental review with tribal and public comment is still pending.
Power and water
In Pacific Power (PacifiCorp) service territory (utility inferred from territory, not company-confirmed); regional supply is hydro-dominant.
Amazon's Aug 2026 community materials state the cooling system will use outside air ~93% of the year, with water-based cooling supplementing during the hottest ~7%.
Notes on the record
~$4.8B, ~300 MW campus near Wallula, Walla Walla County; operator reported (not officially confirmed) to be AWS → confidence reported. Coordinates are the Wallula area centroid. Operator confirmed as Amazon Data Services when the Port of Walla Walla amended the buyer from Advance Phase LLC to Amazon Data Services (Feb 12, 2026 commission vote; >550 acres for >$36M land), confidence upgraded to confirmed. The reported ~$4.8B (DCD) / ~$5B (local) campus figure is an estimate across ~4 phases, not a firm pledge -> investmentUsd omitted. Port projects ~720 direct+indirect jobs at full build-out (projection) -> jobs honest-zero. Eligible for Washington's rural-county server-equipment sales/use-tax exemption (RCW 82.08.986) but no DOR certificate is confirmed -> subsidy honest-zero. Water source and cooling type are undisclosed pending SEPA (no water rights were conveyed in the land deal).
What the record does not establish, and the document that would
In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.
- Tax abatements or other public subsidy
- Permanent jobs promised
Which document closes each gap
- Tax abatements or other public subsidy
- The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
- Permanent jobs promised
- The economic development application or incentive agreement, which usually states a job commitment and a clawback.
