Opposition stopped 4,100 acres of Prince William County data-center plans in about a week
Developers withdrew a 2,100-acre campus for up to 37 data centers in Prince William County, Virginia, in early July 2026 after protests and legal action. In the world's largest data-center cluster, winning local approval is now a risk a buyer has to underwrite before a building goes up.

What happened
- A week after the withdrawal, county officials cited that opposition when they rejected a separate proposal to rezone 2,000 acres elsewhere in Prince William for more data centers.
- For years, many Virginia jurisdictions let developers build data centers without public review as long as the buildings met existing zoning requirements.
- In July 2024, Bren Mar residents in Fairfax County objecting to a proposed 466,000-square-foot data center found local zoning let it proceed without a public hearing.
- In early 2025, Loudoun County, nicknamed Data Center Alley, ended automatic zoning approval for new data centers and began requiring public hearings before decisions.

Why it matters
- constraint Where hearings are required, as in Loudoun, a campus that fits the zoning no longer starts on a date the developer sets, because residents and a board get their say first.
- precedent Prince William officials named public opposition as their reason for denying a rezoning. The next board to face a large application now has that reason on the record.
- decision Developers now have to decide whether to budget up front for underground transmission lines and setbacks from homes, schools and parks, the measures residents rewarded most.
Put the two Prince William County outcomes together and 4,100 acres of planned data-center land fell out of the pipeline in about a week [1]. If all 37 buildings had gone up, the withdrawn campus would have used roughly 57 acres for each one [2]. Both defeats came about two years after the Bren Mar episode in Fairfax [4].
For whoever finances a campus, the risk now sits at the approval stage, before any building goes up. The Fortune account was written by the researchers who ran the survey [12]. It does not name the developers or say what they spent before withdrawing.
For a developer, the more useful finding is which concessions residents value. The researchers surveyed 1,004 residents of northern Virginia and the Richmond area in fall 2025 [8], months before the July withdrawal [5]. Each compared five pairs of policy packages, 5,020 choices in all [3], drawn from six measures that included electricity rates and environmental effects [9]. Residents most strongly backed underground transmission lines and limits on data centers near homes, schools and parks, and they also strongly supported regular reporting of energy and water use [10]. A say before approval ranked second of the six provisions [11].
One path is that projects move to counties that have not added hearings, although the researchers report organized opposition rising nationally as well as in northern Virginia [2]. Another is that approval becomes a negotiated cost, paid for with buried lines, setbacks and disclosure. The third is that public hearings become the place where large campuses are turned down, one county at a time.
I think the second is likelier for sites near the existing clusters. What residents rewarded was specific and visible. A developer can meet the demand to be consulted by going to residents before filing, or rather, before assembling 2,000 acres that only a rezoning can make usable [4]. The counter-case is Prince William itself, where a withdrawal and a denial inside a week [3] point toward the third path. I am wrong if the county turns down its next large application even with buried lines and setbacks attached.
What to watch
- Whether Prince William County follows Loudoun in ending automatic approval for data centers that meet existing zoning.
- Whether the legal action that preceded the 2,100-acre withdrawal produces a ruling that limits other Prince William projects.
- Whether the Richmond area, Virginia's other large data-center cluster, sees organized opposition to large campuses like the fights in Prince William.
