   Proposed
   Walla 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 status, under construction, is not supported by these sources.

Opposition and litigation at this site

Partly. Both documented support and documented opposition to AWS Wallula Gap Campus in Wallula, Walla Walla County, Washington appear in the record, with no clear majority position. 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.

How the community has taken it

Reception is a sourced signal, not an editorial judgment: mixed reception means documented support and documented opposition both exist with no clear majority position on record.

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 campus near Wallula, Walla Walla County; operator reported (not officially confirmed) to be AWS, so the record was marked 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), the record was then marked confirmed. The reported ~$4.8B (DCD) / ~$5B (local) campus figure is an estimate across ~4 phases, not a firm pledge, so no investment figure is recorded. Port projects ~720 direct+indirect jobs at full build-out of its four-phase, 16-building concept (projection), so no jobs figure is recorded; Amazon's FAQ for the three-building application projects 120-150 full-time positions. The application before Walla Walla County (the Amazon Attalia Data Center Campus) covers three buildings of about 220,000 sq ft each on a 134-acre parcel, smaller than the Port's concept, so the land area recorded is that parcel. As of October 2026 no cited source states a capacity figure for the campus, so no planned capacity is recorded. Eligible for Washington's rural-county server-equipment sales/use-tax exemption (RCW 82.08.986) but no DOR certificate is confirmed, so no subsidy is recorded. Amazon's August 2026 community materials describe the cooling as outside air about 93% of the year, with water-based cooling (water-soaked pads) for about 7%, and give the cooling-water source as a new non-potable Columbia River supply system being developed with the Port of Walla Walla, with potable groundwater from the utility as temporary cooling water for about a year while that system is built.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
