Summary

Microsoft names a proposed Wellington datacenter site on about 124 acres it bought in 2024 on Wellington Road in Gainesville, Prince William County, Virginia. It says it has started applying for permits, development has not commenced, and the project remains in early planning and permitting. Remediation of contamination from earlier industrial use continues under an EPA consent order. The county tracks the 117-acre parcel as the pending University Business Park rezoning (REZ2023-00019), with planned buildings MNZ07 and MNZ08. No permit, site work or construction is established. evidence

Location details

Coordinates: 38.79304, -77.58137
Geometry licence: public-record-source-terms
Use scope: Campus locator
Scope class: official_data_center_campus_polygon_centroid
Authority: Official source
Source entity: Campus
Method: official_county_data_center_campus_polygon_centroid
Derivation: direct_geometry
Precision scope: Centroid of Prince William County's University Business Park data-centre campus polygon (117.22 acres, about 1.1 by 1.4 km), which coincides exactly with Microsoft-owned parcel 7497-43-7416. It locates the proposed campus property, not a building, an approved site plan or works. Microsoft's separate 6.5-acre parcel at 5731 Wellington Rd, about 19 m west, is part of the stated 124-acre holding but is outside the county campus polygon.
Horizontal uncertainty: Not reported
The county publishes no positional accuracy for its campus polygons or parcels; the centroid represents a property of about 1.1 by 1.4 km.
Geometry evidence: fd8b7216

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
