The change is zoning text amendment DPA2026-00006, which revises the Data Center Opportunity Zone Overlay District. The county's project page says it limits the overlay to parcels meeting one or more of five eligibility pathways and closes the overlay to future expansion. [Source 1]
The ordinance text posted for the hearing works this way. Parcels stay in the overlay, with by-right data center rights, only if they were already in the overlay and meet at least one test. The tests cover accepted proffers for a data center rezoning, an approved preliminary or final site plan or plat, a final zoning determination, or an application accepted for review within a set window after adoption. In each case the applicant must be pursuing the project in good faith with substantial expenses. [Source 2]
Everywhere else, data centers in office, industrial and B-1 districts now need a special use permit. They remain prohibited in agricultural, residential and several business districts. After adoption, the board will not consider adding properties to the overlay. [Source 2]
Status as of September 22, 2026: Approved, per local reports. The adopted text and final minutes were not yet posted when we checked on September 23, and the county's board staff report did not load for us. We describe the mechanism from the text posted for the hearing.
The Planning Commission recommended approval on September 9 with a 120-day filing window and a 500-foot setback from homes and schools. [Source 1] InsideNova reports the board adopted a 90-day grace period without the buffer. It reports the 500-foot setback is on a separate track, with Planning Commission review in November and a board vote in January 2027. [Source 3] Treat the 90-day figure as reported until the adopted ordinance is posted.
Dominion's application, SUP2025-00009, sought to expand its substation at 13405 Vint Hill Road near Nokesville on a 23.4-acre site. It would have become a 500 kV gas-insulated facility with two 30-foot buildings. The board had deferred the decision on June 23. [Source 5] [Source 6]
Dominion said projects like Vint Hill are "essential to maintaining a reliable grid," according to FOX 5. [Source 4] The reviewed sources do not say what data center load the project was meant to serve or what Dominion will do next.
The reviewed sources do not say how many parcels or acres remain in the overlay, or how much planned data center capacity falls outside it. Before the vote, Supervisor Tom Gordy said no data center company had filed an application in over two years "because there's no power." That is his characterization, reported by InsideNova.

Prince William is one of the core Northern Virginia supply markets. This vote does not remove existing buildings or projects with qualifying approvals. It does change the path for everything else, from an administrative review to a public board decision.
For buyers, the practical effect is on future supply timing, not current inventory. Projects already approved or filed in time keep their route. New sites face a slower and less certain process. The Vint Hill rejection adds a second constraint on power delivery in the county's western area.
When a provider quotes future Prince William capacity, ask two things. Does the site qualify under the grandfathering tests, or does it still need a special use permit? And which substation and transmission projects does its power date depend on?
The adopted ordinance text and minutes were not posted as of September 23. The reviewed sources do not state how many parcels or acres remain in the overlay or what load the Vint Hill substation would have served.
