The record, newest first
Supervisors turned down the applicant's deferral request 7-1, heard about five hours of public comment, then denied the plan amendment 8-0; staff had recommended denial because the land lies outside the data center overlay district. (InsideNoVa, July 7, 2026; Virginia Mercury, July 9, 2026)

- Coordinates approximate, near Sanders Lane north of Gainesville by the Loudoun County line; no address reported.
- Acreage reported as about 1,940 in the amendment and 'nearly 2,000' overall.
