The Prince William Board of County Supervisors will vote Tuesday on whether to initiate a comprehensive plan amendment that could allow a large data center campus in the county.
The request, known as the Dulles South Innovation Center, was filed by Sanders Lane Assemblage I LLC.
If initiated, the amendment could allow data centers, an electrical substation, and related uses, including training and research facilities, followed by a companion rezoning to Planned Business District.
The property is north of Sudley Road along the Sanders Lane corridor, directly north of the Prince William Digital Gateway Special Planning Area. High-voltage transmission lines run through the site.
The proposal follows the withdrawals of QTS Data Centers and Compass Data Centers from the Prince William Digital Gateway, a 27 million-square-foot data center project near Manassas National Battlefield Park. The Board of County Supervisors approved that project in November 2022.
County planning staff reviewed the Dulles South Innovation Center and recommended that the board not initiate the amendment, citing concerns about infrastructure capacity, environmental effects, and land-use compatibility.
According to the staff report, full buildout could reach up to 43 million square feet of data center space and add about 4,600 employees. Daily traffic could increase from about 2,535 trips under current conditions to more than 42,570. The site does not have public water or sewer service, and staff said extending those systems through rural-designated land would conflict with the county’s comprehensive plan.
Staff also cited tree loss, effects on rural character, and incompatibility with surrounding agricultural land and the nearby Catharpin Hamlet.
The applicant said the site was suitable because of its proximity to existing transmission infrastructure and its location as a northern extension of data center development.
Opponents plan to rally before Tuesday’s meeting. The Coalition to Protect Prince William County said it will hold a press conference and rally at 1 p.m. outside the James J. McCoart Administration Building, 1 County Complex Court in Woodbridge.
Coalition Executive Director Elena Schlossberg said the proposal would force residents to compete with corporations for power during extreme heat while exposing communities to noise and emissions from diesel generators.
Expected speakers include U.S. Rep. Suhas Subramanyam, state Sen. Danica Roem, Del. Josh Thomas, and residents of Prince William and Loudoun counties affected by data center development.
