Loudoun County officials in Virginia are due to discuss a possible data centre moratorium on Tuesday, as growing opposition to the industry’s rapid expansion puts pressure on the community’s long-standing economic model.
The Board of Supervisors is expected to consider a proposal to pause new data centre applications at its meeting in Leesburg at 4pm. The initiative is being led by Algonkian District Supervisor Juli Briskman, who has argued that the county needs time to assess the impact of further development.
The debate follows a 6-1 vote in July directing county staff to examine whether a pause could be introduced while officials review planning and zoning standards. The proposal would apply to new data centre projects and associated substations, although its legal basis remains uncertain.
Loudoun County’s own guidance says Virginia law may prevent the board from imposing a blanket moratorium because applications must generally be considered on their individual merits. County staff have been asked to provide legal advice on whether any form of development pause could lawfully be implemented.

Residents living near the facilities have raised concerns about noise, possible health effects, pressure on the electricity grid and the infrastructure needed to support increasingly power-intensive operations.
Data centres have also become a central pillar of the county’s finances. Briskman said they account for almost half of Loudoun’s revenue, a level of dependence she described as “so fiscally irresponsible”.
“Big companies. Big corporations, they come in, they build their chemical plants, they build their manufacturing facilities and then they leave,” she said.
Loudoun, known as the centre of northern Virginia’s “Data Centre Alley”, has adopted tighter controls in recent years. The board approved amendments to its comprehensive plan and zoning rules in March 2025, while further work on data centre standards and locations is continuing.

The proposed pause comes as county supervisors also examine whether some older data centre applications should retain so-called grandfathered rights under previous planning rules. Any decision on a moratorium is likely to face scrutiny from developers and could trigger further debate over the balance between economic growth, public services and the impact on local communities.
