Loudoun County, Virginia, long regarded as the data center capital of the world, is weighing a formal pause on new data center applications while its planning commission has already turned away a sprawling proposed campus that would have covered more than 300,000 square meters of land.

A Moratorium Motion Takes Shape

Supervisor Juli E. Briskman introduced a motion at the county board of supervisors meeting on July 22, 2026, that could set the stage for a moratorium on new data center applications. The motion passed by a vote of 6 to 1.

It directs county staff to research the legality of such a moratorium and to present an item formally establishing a pause at a board of supervisors meeting scheduled for September 15.

Briskman framed the move as a necessary moment of reflection for a county that has seen data center development outpace regulatory scrutiny.

"Loudoun became the data center capital of the world in large part because data center development occurred with little oversight and before the full impacts were studied or understood," she said.

"This pause would offer the County an opportunity to conduct its due diligence and establish appropriate policies, regulations, and standards so that we can better protect our communities and natural resources."

The lone dissenting supervisor voiced concern about the legal exposure such a move could create. "I cannot imagine we would not be sued if this were passed in September," the supervisor said, signaling that the path to a formal moratorium is unlikely to be without challenge.

Planning Commission Turns Away the Spring Valley Technology Park

One day after the moratorium motion passed, on July 23, the county's planning commission rejected an application to build what would have been a 3.25 million square foot data center campus.

The proposed development, known as the Spring Valley Technology Park, would have required the rezoning of approximately 325 acres of land situated on the east side of Evergreen Mills Road, south of Reservoir Road, west of Beaverdam Drive, and north of Ryan Road.

The project as conceived would have included 12 data center buildings, three utility substations, and what the application described as utility-scale energy storage use.

The rejection came amid broader concerns about the pace and scale of data center expansion across the county.

New York-based developer Active Infrastructure has been pursuing the Spring Valley Technology Park since October 2024.

The company was founded by Jeffrey Zygler, who previously served as a partner at real estate investment and management company Dermody Properties and as president of development at KTR Capital Partners.

The Weight of Becoming the World's Data Center Capital

Loudoun County's position as the global hub for data center activity has been built over years of rapid development, but that status is now generating friction at the local government level.

The near-simultaneous rejection of a major campus application and the advancement of a moratorium motion reflect a county grappling with the cumulative consequences of hosting the largest concentration of data center infrastructure anywhere in the world.

Briskman's comments tied the moratorium proposal directly to what she described as a historical lack of oversight, suggesting that the county's growth in this sector preceded the establishment of policies equipped to manage its impacts on communities and natural resources.

The September 15 board meeting will be a critical date for determining whether that pause becomes a formal reality.

The rejected Spring Valley project illustrates the scale at which developers have been seeking to build in the region.

A 325-acre rezoning for 12 buildings and associated utility infrastructure represents the kind of large-footprint development that has become a flashpoint in Loudoun's evolving relationship with the data center industry.

Legal and Political Uncertainty Ahead

The road to a moratorium remains uncertain. The board's directive requires staff to first assess whether such a pause would be legally defensible before any formal establishment of a moratorium is brought to a vote in September.

The dissenting supervisor's warning that litigation would likely follow suggests that legal challenges from developers and landowners could complicate or delay the process.

Whether the September 15 meeting produces a formal moratorium vote, a modified version of a pause, or further study remains to be seen.

What is clear from the 6-1 vote and the planning commission's rejection of the Spring Valley campus is that a significant shift in political sentiment is underway in a county that has for years welcomed data center investment with relatively few restrictions.
