Two AWS centers under construction (reported OPB)
OPB reported (Sep 2025) that Amazon Web Services has built dozens of data centers across Umatilla and Morrow counties and was already building two centers in Hermiston when the City Council voted to annex about 800 acres with a hyperscale data center designation to attract more of the industry. No company was attached to the annexed land at the time of the vote (OPB, Sep 10 2025)
UGB / ~810-acre hyperscale overlay (reported Hermiston Herald)
Hermiston Herald reports the City Council (Aug 25 2025) approved first readings to expand the urban growth boundary and set aside about 810 acres for future large-scale data center development under a Hyperscale Data Center Overlay Zone limited to data-center use. City planner Clint Spencer cited the city's 2024 Economic Opportunities Analysis finding a shortage of 100-acre industrial sites, with two data centers already under construction inside city limits (Hermiston Herald, Aug 26 2025)
Jobs / valuation framing (reported local)
Hermiston Herald cites city projections that full data-center buildout on the expanded UGB could bring hundreds of millions of dollars in new valuation and job creation, and notes Umatilla County information-sector jobs (including data-center operations) rose from 170 to 880 since 2018. OPB separately cites a 2024 city-commissioned economic analysis projecting more than 1,500 data-center jobs over 20 years. Treat as municipal projections, not AWS-disclosed headcount (Hermiston Herald, Aug 26 2025; OPB, Sep 10 2025)
