Opposition and litigation at this site

Nothing on record as of September 17, 2026. No lawsuit, organized opposition, or contested hearing over Equinix Seattle SE3 in Seattle, King County, Washington 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.

A new status, a permit, a reception finding, or a lawsuit. Nothing else, ever.

Notes on the record

A separate building from the Westin Building (2001 6th Avenue), which the projection already tracks as Digital Realty SEA10 and which houses Equinix SE2. Baxtel loosely describes SE3 as 'in the Westin Building'; OSM maps it as its own five-storey building at 2020 5th Avenue, sourced to a King County Assessor parcel record, and that is the location used here. No capacity asserted - Equinix does not publish one and the megawatt figures circulating on colocation marketplaces were not retrieved from a primary source this session.

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.
