Opposition and litigation at this site

Nothing on record as of September 10, 2026. No lawsuit, organized opposition, or contested hearing over QTS Phoenix 4 in Tolleson, Maricopa County, Arizona 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.

Notes on the record

Second QTS site in the Phoenix market, in Tolleson. The operator page is a community-partnership page and discloses no capacity, acreage or timeline, so those fields are omitted rather than estimated. Status recorded as under_construction on the strength of 'under development' plus a fixed street address; a maintainer may want to confirm against a Tolleson or Maricopa County permit before publishing. Coordinates geocoded from the cited address via the US Census geocoder.

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.

  • Power capacity in megawatts
  • Cooling method and water use
  • Tax abatements or other public subsidy
  • Permanent jobs promised
  • Land area
  • How the community has received it
  • Which utility serves it
Which document closes each gap
Power capacity in megawatts
The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
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.
Land area
The rezoning application, the plat, or the deed recorded with the county.
How the community has received it
Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
Which utility serves it
The electric service agreement or the utility's filing with the state public utility commission.

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.
