Opposition and litigation at this site

Nothing on record as of July 23, 2026. No lawsuit, organized opposition, or contested hearing over TierPoint Hawthorne (11 & 17 Skyline Drive) in Hawthorne, Westchester County, New York 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.

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

Notes on the record

Two adjacent buildings on a shared campus with Westchester County Medical Center and New York Medical College: 11 Skyline Drive (46,000+ sqft total, 28,000+ sqft raised floor, backup generation two 2MW + three 1MW) and 17 Skyline Drive (172,000+ sqft total, 28,000+ sqft raised floor, backup generation two 2,000kW). No whole-campus IT-load MW figure is publicly disclosed, generator specs are backup capacity, not confirmed critical load, so no capacity is recorded. SOC 1/2 Type II, HITRUST, GLBA, HIPAA, PCI-DSS, NIST SP 800-53, ISO 27001, ITAR-registered. As of July 2026, no AI/HPC marketing had been found. Coordinates fall within the Westchester County tax parcel for 11 Skyline Drive (116.7-1-17), one of the two buildings.

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 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.
