Why data centers pose an outsized threat to Eastern Oregon's air quality — 'In Hermiston, Amazon has hired hundreds of employees and contractors to staff its two hyperscale data center campuses'; 'Hermiston has given the company 15-year tax breaks for each campus' ↗2026-08-14

Hermiston clears the way for data center industry — two data centers under construction in Hermiston; city council voted Sept. 9, 2025 to annex 800 acres zoned for hyperscale data center use ↗2026-08-14

Umatilla County Ordinance 2025-11 (Oct. 15, 2025) — co-adopts the Hermiston urban growth boundary expansion of approximately 810 acres and inserts a new section 157.058 'Hyperscale Data Center (HDC) Overlay' after the Heavy Industrial Zone; legal descriptions total roughly 824 acres across Sections 21, 25, 26, 27 and 28, Township 4 North, Range 28 East ↗2026-08-14

Hermiston adds 810 acres to support future data centers — AWS operates multiple campuses in Hermiston, Umatilla and Boardman; 2024 Economic Opportunities Analysis cited a lack of property for hyperscale data center development ↗2026-08-14

Small eastern Oregon city could be next hotspot for big data centers — enumerates Amazon's Umatilla County footprint as of Sept 2023: two existing data centers in Umatilla and two more under construction there plus two with tax-break agreements; one operating data center in unincorporated Umatilla County near Hermiston, one under construction within Hermiston city limits, and two further Hermiston projects with negotiated tax deals ↗2026-08-14
