The Prince William County Board of County Supervisors convened on July 29, 2025, to discuss a significant rezoning application from Iron Mountain, a data center operator seeking to expand its existing campus along Wellington Road. The proposed site, approximately 18.89 acres, is currently zoned for Office Flex and a small portion for Planned Mixed Development. Iron Mountain aims to rezone the property to M-2, aligning it with the surrounding data center developments.

The rezoning proposal is part of a broader strategy to enhance the area's industrial capabilities, particularly in data center operations, which are deemed a principal use within the I-3 Industrial Tech Flex designation of the county's comprehensive plan. The proposed development includes a building with a maximum height of 75 feet, which encompasses rooftop mechanical equipment, and aims to maintain a Floor Area Ratio (FAR) of 0.35, consistent with the I-3 guidelines.

A key aspect of the discussion centered on the potential impact of the new data center on the nearby Arcadia Run Apartments, located approximately 411 feet away. Concerns were raised regarding noise, visual massing, and traffic implications. In response, Iron Mountain has committed to several mitigation measures, including sound attenuation for rooftop equipment and enhanced landscaping buffers to minimize visual intrusion. The applicant has also proposed to exceed the comprehensive plan's requirement for open space, offering nearly 48% of the site as open area.

During the meeting, supervisors expressed concerns about the adequacy of the proposed buffers and the overall design's compatibility with the residential community across the street. The planning staff acknowledged these concerns but noted that the project aligns with the county's goals for industrial development. They emphasized the importance of balancing the needs of the data center with the residential community's concerns.

The board also discussed the implications of the proposed access points to the site, with one access point removed to enhance the buffer zone. The potential for traffic signals at the site was debated, with some supervisors advocating for improved traffic management to facilitate safer access for residents of Arcadia Run.

In conclusion, the board's discussions highlighted the complexities of integrating industrial development within residential areas. While the staff recommended approval of the rezoning application, the ongoing dialogue reflects a commitment to addressing community concerns and ensuring that development aligns with the county's strategic vision. The board is expected to continue evaluating the proposal, balancing economic growth with the needs of local residents.
