Local votes and rules
📌 Other
Supervisors voted unanimously to ask staff for a legal analysis of ending the 2025 grandfathering rule, due at the October 6, 2026 board meeting. Until the board acts, the rule stays in effect.
⏸️ Pause on new data centers
Supervisors voted 7-1 to pause new data center applications for 12 months while the county rewrites its data center rules. The county attorney had warned that true moratoria are rarely allowed in Virginia.
🗺️ Zoning change
Supervisors voted 7-2 to end by-right data centers. New data centers now need a 'special exception', with public hearings before the planning commission and the board.
📌 Other
On the same night, supervisors voted 5-4 to 'grandfather' data center applications already in review, so they can still be approved by staff without a public hearing. In September 2026, 17 such applications (about 11 million square feet) were still in review.
