Loudoun County’s Zoning Loophole Turns Data Center Alley Into a National Warning

Buddy Rizer was a former radio DJ who had stumbled into local economic development work when, in 2007, he was tasked with finding Loudoun County, Virginia a new source of revenue as the collapsing housing bubble threatened a county where more than 80 percent of revenue came from residential real estate. His fix was to fill the abandoned dot-com-era buildings and unused fiber optic cable AOL had left behind with something new: data centers. A feature published this week by The Verge traces what happened over the next two decades, and Loudoun’s experience now reads less like local history and more like a preview of the fight breaking out over AI infrastructure everywhere else in the country.

Loudoun is home to roughly 250 data centers packed into a fraction of its 515 square miles, the densest concentration in the world, a status that earned it the nickname Data Center Alley. For most of two decades, that arrangement meant quiet, compounding prosperity: falling property tax rates, new schools, and a tax base that grew faster than the county could spend it. Only in the past few years have residents started treating that arrangement as a bargain they never explicitly agreed to, and the terms of that bargain are hardening into a template the rest of the country is now negotiating in real time, in at least one case at gunpoint.

A Zoning Decision Nobody Noticed in 2000

The mechanism that made Loudoun’s buildout possible predates the AI boom by two decades, and it had nothing to do with data centers specifically. In 2000, the county’s zoning administrator classified data centers as “office parks,” a paperwork decision that let them be built on any land already zoned for office use “by right,” meaning developers never had to apply for the rezoning or public hearing that other commercial and industrial uses require. Unlike a heavy manufacturing plant, which faces real restrictions on how close it can sit to homes, a data center could go up anywhere an ordinary office building already could.

That single classification is why, twenty years later, county officials describe their leverage over new projects as far weaker than most residents assume. Board of Supervisors Chair Phyllis Randall told The Verge that when her office tried to negotiate concessions from one applicant on January 5, 2023, the developer’s response was blunt: “Forget it. I’m going to go build a data center.” Randall said she “pretty much begged them not to” walk away. Her broader point, as she put it to The Verge, is that once a developer can build “by right” with no negotiated conditions at all, the community typically ends up with far less than it would have gotten if officials had managed to extract concessions before ground broke. Virginia law compounds the imbalance: Loudoun cannot enact a moratorium on new data center construction without the state’s permission, and both the Biden and Trump administrations have treated the AI infrastructure buildout as a national priority neither has been inclined to slow down.

The Tax Math That Bought Two Decades of Quiet

What the zoning loophole started, the county’s own budget math has kept running. Tax revenue from data center computer equipment climbed from about $150 million a decade ago to an estimated $1.1 billion in 2025, and that industry now accounts for roughly 38 percent of the county’s General Fund revenue in its FY2026 budget, according to Moneywise’s analysis of county data. The county has used that revenue to build 22 new schools over the past 15 years and, per The Verge’s reporting, generated $35 million more than its entire operating budget required in 2024 alone.

The clearest evidence shows up in homeowners’ own tax bills. Loudoun’s own government reporting shows the county’s real property tax rate has fallen every year for a decade, from $1.145 per $100 of assessed value in 2016 to $0.805 in 2026. The Verge cites a longer decline covering a wider window, from about $1.29 to 80 cents per $100 of assessed value since 2008. The two figures come from different starting points, but they tell the same underlying story: for most of Loudoun’s two decades hosting the world’s densest concentration of data centers, saying yes to the industry was nearly invisible to the median homeowner, while saying no would have meant finding a different way to pay for schools, roads, and a lower tax bill that residents had come to expect.

What Living Next to Data Center Alley Looks Like Now

The Verge’s reporting captures how that arrangement feels different up close than it does in a budget spreadsheet. Longtime resident Julie Bolthouse points out a former daycare center near the old AOL campus, now surrounded by construction equipment for more data centers. “That used to be a major daycare center here in the heart of Data Center Alley, because there were so many people who worked here,” she told the outlet. “Now it’s just these big, giant computer energy-guzzling, water-guzzling warehouses.” Data centers also run their own backup diesel generators and gas turbines, which are meant to stay off except during power outages. Near one Ashburn facility, Bolthouse pointed out visible emissions plumes that turned out to be coming from diesel generators; The Verge later learned they were only running because of an emergency circuit issue, not routine operation, and that generators at that site are not supposed to run at all on days with already-poor air quality. On other days, a nearby resident named Lindsay Shaw told the outlet, it is the facility’s gas turbines that produce a high-pitched squealing noise instead.

A Transmission Line Through the Backyard

For one Loudoun resident identified in the piece as Hu, the shift arrived as a phone call. She had lived in the county since 2000 without hearing the “Data Center Alley” nickname until a reporter used it last year. Then Dominion Energy called: a new transmission line connecting two substations would cut directly through her backyard. “This is just the first power line coming through a neighborhood,” she told The Verge. “Where do you think the rest of the power lines [are] going to go through?” She predicts that within five to ten years, the sky over Ashburn will look “like a spiderweb” of new transmission infrastructure, and says that if she loses the fight to keep her yard intact, she would have no choice but to leave.

An Entire Neighborhood, for Sale Whether It Wants to Be or Not

The clearest sign of how far the calculus has shifted is not a single transmission tower but an entire subdivision. In March 2026, InsideNoVa reported that homeowners in the Regency, a roughly 130-acre community off Waxpool Road in Ashburn, were being offered around $4.4 million per acre, close to $576 million in total, to sell the entire neighborhood for a planned six-building, 432-megawatt data center campus. Community Works LLC, an affiliate of the Regency’s homeowners association, was reportedly handling entitlement negotiations on residents’ behalf, though the identity of the ultimate buyer was withheld under a non-disclosure agreement and no formal application had been filed with the county at the time of reporting. It is a strange kind of leverage: an offer generous enough that some homeowners want to take it, in a neighborhood that exists at all only because data centers made the tax base rich enough to build it in the first place.

The Backlash Has Gone National, and in One Case, Violent

Loudoun’s slow-motion reckoning is now compressing into a much faster national one, driven by the generative AI boom’s sudden demand for what the industry calls compute. There are already more than 3,000 operational data centers in the United States, with roughly 1,500 more in some stage of development, according to an April 2026 Pew Research Center analysis. Pew found that 67 percent of planned data centers are headed to rural areas, a sharp reversal from the 87 percent of existing facilities that sit in urban ones, with the South and Midwest absorbing three-quarters of new construction.

Unlike Loudoun, which had two decades to adjust, many of those newer host communities are compressing the entire arc, tax windfall, community anger, and open conflict, into a matter of months. In Indianapolis, City-County Councilor Ron Gibson publicly backed the Metropolitan Development Commission’s April 1, 2026 vote approving a $500 million Metrobloks data center in his district, saying “this project met those standards” for approval. Days later, according to CBS News, someone fired 13 rounds into the front door of Gibson’s home after midnight, waking him and his 8-year-old son, and left a note reading “NO DATA CENTERS” in a zip-closed bag on his doorstep. Neither was physically harmed, and the FBI assisted local police in an investigation that had not identified a suspect. Council President Maggie Lewis condemned the attack: “Violence, threats, and intimidation are not forms of dialogue: they are attacks on our shared commitment to democracy, civil discourse, and community safety.”

The Indianapolis shooting is an outlier in its violence, not in the underlying sentiment. National polling cited by The Verge shows many Americans do not want to live near a data center, New York and Texas have both moved to slow new construction over concerns about strained electricity grids, and data center opposition has become, in the Verge’s framing, a genuine cross-partisan issue heading into this year’s midterm elections. sxz.io has covered pieces of that grid strain directly: PJM’s decision to curtail power to new data centers starting in 2027 and Amazon’s Texas gas plant, which regulators project could become the country’s single largest emissions source, are both downstream of the same buildout Loudoun helped normalize two decades ago.

Why Loudoun Can’t Just Say No

What makes Loudoun’s position instructive, rather than simply cautionary, is how little room officials have to reverse course even now that residents are asking them to. The 2000 zoning classification that let data centers build “by right” is still on the books, state law still forbids a unilateral local moratorium, and federal policy under two consecutive administrations has pushed in the same direction. Randall’s own account of her job, as relayed to The Verge, is essentially triage: not whether to allow data centers, a question the county effectively answered by accident in 2000, but how many, under what conditions, and with how much public benefit attached. Meta’s Mark Zuckerberg made a similar calculation explicit in his own recent AI strategy essay, pledging a reported $1 billion fund aimed at communities hosting Meta data centers, an acknowledgment that buying local goodwill has become a real line item in AI infrastructure budgets, not an afterthought.

The Lesson for Everywhere Else

Loudoun residents have taken to calling their county the canary in the coal mine of data center development, and the metaphor holds up better than most. The county’s twenty-year experience shows both halves of the trade at once: a tax windfall real enough to cut property taxes every year for a decade, and a community cost that took most of that time to become visible, by which point the zoning was already locked in and the industry’s leverage in any negotiation had already hardened. For the hundreds of newer host communities now working through the same decisions in a fraction of the time, the uncomfortable part of Loudoun’s story is not the noise or the transmission towers. It is the fact that by the time a community fully understands what it agreed to, the agreement is usually already very difficult to undo.
