Luckstone Cochrane Mill proposes 989,000 square foot data center development

A significant proposal for a new data center in Loudoun County is stirring debate among planning commissioners, as discussions unfold regarding its potential environmental impact and compliance with local zoning regulations. The Luckstone Cochrane Mill project, which aims to develop nearly 1 million square feet of data center space, has raised concerns about building height and its effects on nearby waterways.

During the April 10, 2025, Planning Commission work session, Allison Bridal from the Department of Planning and Zoning presented the application, highlighting that the property is currently undeveloped and part of the Buckstone Quarry. The proposal includes rezoning the site to allow for data center construction, with a maximum building height of 70 feet—significantly reduced from an earlier request of 105 feet.

Despite these adjustments, staff members expressed ongoing concerns about the project's alignment with the 2019 general plan, which recommends a maximum height of 48 feet for the area. Staff emphasized the need for increased setbacks and enhanced landscaping to mitigate visual impacts from Cochran Mill Road, where the buildings would be most visible.

The project also faces scrutiny regarding its potential effects on Sicklin Creek and surrounding natural resources. Staff noted that the proposed layout could significantly impact local streams and waterways, urging the applicant to consider relocating buildings to minimize environmental disruption. The applicant has committed to various environmental mitigations, including tree conservation and reforestation efforts, but staff remain cautious about the feasibility of these plans.

As the commission deliberates, the outcome of this proposal could set a precedent for future developments in the area, balancing economic growth with environmental stewardship. The next steps will involve further discussions and potential revisions to address the concerns raised by staff and commissioners.
