Amazon (AWS) campus, Arlington Mesa, Gilliam County
About 400 acres above Arlington that Amazon bought for a future campus, which it says could one day match its Morrow and Umatilla footprint, with work waiting on electric power.

Conflicts and open questions
- The map point is approximate, placed from the mesa and airport road location.
- Sources differ on tax tools: The Times-Journal says the county set up an enterprise zone at the mesa, while The Oregonian says the county does not qualify for the standard program and would use the Strategic Investment Program.
- No Gilliam County Court, city planning or DEQ record for the campus was among the sources reviewed. Whether the governor's DEQ permit pause changes this schedule was not reported.
The full record
- Status note
- Amazon owns the mesa land. In July 2026 the city's engineer said AWS was waiting for a clearer power picture, and The Times-Journal reported construction likely in 2029 with power sought by 2031; no land use application or air permit was found.
- Power note
- No power figure in the sources reviewed. Amazon's wind purchase of over 200,000 MWh a year is not a measure of campus load.
