Loudoun County, Virginia, pauses new data center applications amid resident backlash
Loudoun County, Virginia, has become the world’s largest data center hub, generating substantial tax revenue but prompting growing concerns about noise, pollution, power demand and property values. The Loudoun County Board of Supervisors adopted zoning changes requiring future projects to receive board review and voted to pause new data center applications for one year.
Loudoun County has more than 230 data center buildings and receives billions of dollars in related tax revenue, helping fund parks, schools and lower property tax rates. The rapid expansion has also brought transmission infrastructure, strained the power grid and increased concerns about noise, emissions, visual impacts and declining property values in nearby neighborhoods.
Residents and environmental advocates have increasingly opposed the industry, including Vantage Data Centers’ VA2 facility near Aldie, which uses an on-site gas power plant because of limited grid capacity. Vantage said state regulators found the facility’s emissions legal, while a study commissioned by the Piedmont Environmental Council projected significant health-related damages under worst-case assumptions.
The Loudoun County Board of Supervisors has responded by adopting zoning language requiring future data center projects to come before the board and approving a one-year pause on new applications while it reviews county policies. Supervisors have also opposed a major transmission line proposal and pushed back against Amazon’s plans for data centers at a former George Washington University campus.
