The 3 tables below were prepared by ChatGPT on the prompts containing: “top 5 most expensive projects, private or government, that have ever taken place within Salem, OR.”, “County of Marion”, and “State of Oregon”.
Date: August 7, 2026.
| Date | Name | Amount | Source |
|---|---|---|---|
| 2016–present | Oregon State Capitol — CAMS Phases I–III | $595.7 million | Oregon Legislature: $59.9M + $70.8M + $465M (Oregon Legislature) |
| 2022–present | Salem Safety and Livability Bond capital program | $300 million | City of Salem council materials; voters approved $300M in 2022 |
| 2008–2011 | Oregon State Hospital Replacement — Salem | $280 million | Engineering News-Record (ENR) |
| 2020–2022 | Salem Hospital A2 / seven-story patient tower | $235 million | Salem Reporter (Salem Reporter) |
| 2008–c.2018 | Keep Salem Moving transportation capital program | $121+ million | City program: $100M bond plus $21M+ outside funding |
So the relevant Salem comparison remains enormous:
$5.1 billion ÷ $595.7 million ≈ 8.6.
In other words, the stated Verrus investment would be roughly 8½ times the largest Salem capital undertaking I can identify, even when the comparison includes the entire multi-phase State Capitol reconstruction program. The $5.1 billion figure is independently reported for Oakline/Verrus. (w.media)
On a strict geographical basis—counting projects whose stated cost can properly be attributed to facilities within Marion County—the top five I can substantiate are presently the same five, because Salem contains the county’s largest documented capital projects:
| Date | Name | Amount | Source |
|---|---|---|---|
| 2016–present | Oregon State Capitol — CAMS Phases I–III, Salem | $595.7 million | Oregon Legislature (Oregon Legislature) |
| 2022–present | Salem Safety and Livability Bond program | $300 million | City of Salem |
| 2008–2011 | Oregon State Hospital Replacement, Salem | $280 million | Engineering News-Record (ENR) |
| 2020–2022 | Salem Hospital patient tower | $235 million | Salem Reporter (Salem Reporter) |
| 2008–c.2018 | Keep Salem Moving | $121+ million | City of Salem |
One historically significant Marion County project that does not quite make this nominal-dollar top five is the federal Detroit and Big Cliff Dam project, completed in 1953 for $62.729 million. (Oregon Encyclopedia) In inflation-adjusted dollars it would move dramatically upward, which is why I think your eventual statement should expressly say “nominal project dollars” if that is the measure you use.
There are also two important exclusions. The 2018 Salem-Keizer School District bond program grew to more than $750 million, but the district and expenditures span both Marion and Polk counties, so I would not attribute the entire $750M to Marion County. (Salem-Keizer Public Schools) And Amazon’s enormous 3.84-million-square-foot Woodburn fulfillment center is clearly a major Marion County project, but I have not found a reliable published construction-cost figure; the publicly documented $27 million was the land purchase, not project cost. (City of Wilsonville Oregon)
Once we expand statewide, the character of the comparison changes because Oregon has hosted semiconductor and hyperscale-data-center campuses involving multi-billion-dollar investment programs:
| Date | Name | Amount | Source |
|---|---|---|---|
| 2023–present | Intel Hillsboro technology-development expansion / modernization | $36+ billion | Intel / City of Hillsboro (Hillsboro Oregon) |
| 2006–present | Google The Dalles data-center campus — cumulative Oregon investment | $7+ billion | Google (Google Data Centers) |
| 2025–present | I-5 Rose Quarter Improvement Project | $3.6 billion current estimate | Current 2026 estimate (Axios) |
| 2015–2026 | Portland International Airport main-terminal reconstruction | $2.15 billion | Port of Portland; completed June 2026 (Port of Portland) |
| 2010–present | Meta/Facebook Prineville data-center campus | $2+ billion | Meta (Meta Data Centers) |
There is an important methodological qualification to that Oregon table. Intel’s $36 billion and Google’s $7+ billion are multi-year campus/investment programs, rather than single buildings. Meta’s $2+ billion is similarly cumulative campus investment. That actually makes them reasonably useful comparators for Verrus, because the $5.1 billion Verrus number likewise describes a multi-building data-center campus, rather than the cost of one building.
