Spring Valley Tech Park

Operator not disclosed. Filed.

Spring Valley Tech Park (application LEGI-2024-0074) proposes 12 data center buildings and 3 substations across about 325 acres and 3.54 million square feet off Evergreen Mill Road in Ashburn, near Beaverdam Reservoir. The Loudoun County Planning Commission voted unanimously on July 23, 2026 to recommend denial, citing incompatibility with the Transition Policy Area and concerns over impacts to the reservoir, water resources, and generator noise and pollution. No Board of Supervisors hearing date has been reported yet for a final vote.
