Opposition and litigation at this site

Nothing on record as of August 26, 2026. No lawsuit, organized opposition, or contested hearing over Iron Mountain DEN-1 Denver Data Center in Denver, Denver County, Colorado appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.

If you live near this site and something is happening that this page does not show, that is worth telling us. Send us the document and it goes in the record with the source attached. For sites where opposition is already established, see every contested site we track.

About 180,000 sq ft (113,000 sq ft of IT space) and 14.4 MW on a 6-acre campus in the Elyria-Swansea industrial area, in a retrofitted 1946 building. Uptime Tier III-certified construction; operator cites a 1.2 PUE. Roughly half a mile from the CoreSite DE3 site but a separate operator and parcel.

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

  • Cooling method and water use
  • Tax abatements or other public subsidy
  • Permanent jobs promised
  • How the community has received it
Which document closes each gap
Cooling method and water use
The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
The economic development application or incentive agreement, which usually states a job commitment and a clawback.
How the community has received it
Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.

Have one of these documents? Send it to us and we will add it to the record with attribution.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
