Updates, newest first

  1. Oct. 14, 2026 Council member Rob Andrews said Vantage agreed to look at alternative sites in Aurora; Vantage did not respond to the Gazette. (Colorado Politics / The Denver Gazette, Oct. 14, 2026)
  2. Oct. 1, 2026 Mayor Mike Coffman wrote that the project must be stopped even at the risk of a lawsuit and said he would ask the council to vote it down; Vantage said it wanted the project judged on verified facts. (Colorado Politics / The Denver Gazette, Oct. 2, 2026)
  3. Sept. 28, 2026 About a hundred Green Valley Ranch residents, including people from the 55-plus Reserve community, packed a council meeting to oppose the plan; the city attorney has said the industrial zoning permits data centers and that denying a plan that meets the code could expose the city to liability. (Colorado Politics / The Denver Gazette, Oct. 2, 2026; Colorado Politics / The Denver Gazette, Oct. 14, 2026)
  4. Sept. 28, 2026 Axios reported that Vantage's design calls for two two-story buildings of about 860,000 sq ft, 334 MW of IT capacity, roughly 500 MW of total demand and 28 emergency diesel generators, and that the project still needs a state air-quality construction permit. (Axios Denver, Sept. 28, 2026)
  5. Aug. 25, 2025 Vantage submitted the Trident application to the city. (Colorado Politics / The Denver Gazette, Oct. 15, 2026)

Conflicts and open questions

  • Building area differs: Colorado Politics cites 1.5 million square feet on 108 acres from the city portal, while Axios describes two buildings totaling about 860,000 square feet; residents' documents cited at least 60 generators against the 28 in Vantage's design (Axios).
  • County: the Census geocoder places the reported corner (E-470 and East 48th Avenue) in the Adams County part of Aurora.
