Notes on the record

Application LEGI-2024-0074. Ten data center buildings up to 100 feet tall, three electrical substations and a backup power storage facility on the east side of Evergreen Mills Road south of Watson Road, in Loudoun's Transition Policy Area near Goose Creek. Rezoning sought from Transitional Residential-10 to Industrial Park. Sources give different footprints, Loudoun Now reports 325 acres and 3.25 million sq ft; Loudoun Wildlife Conservancy reports 362 acres and up to 3.5 million sq ft, so no land area is recorded here rather than picking between them. The southern half comprises 13 parcels of the Spring Valley subdivision with existing single-family homes; one parcel holds an 1880s house and a family cemetery.

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
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.
Which utility serves it: The electric service agreement or the utility's filing with the state public utility commission.
