Loudoun puts data-center noise, power and siting rules under review
Loudoun County’s Phase 2 planning project examines the practical impacts of data centers, with public engagement scheduled for September 2026.
The short version
- The county approved the Phase 2 project plan on September 16, 2025.
- Noise, building height, substations and onsite power are among the subjects under review.
Why it matters. Local planning rules shape how a data center can operate alongside homes and other uses.
The debate reaches the rulebook
Loudoun’s Phase 2 project moves the discussion from general arguments about AI to the conditions around buildings: noise, height, substations, onsite generation and energy storage.
The county describes a review of compatibility through its special-exception process, not a remapping exercise. Its published schedule includes September open houses and later hearings. Those are planned steps, not final rules.
For neighbors and developers, the eventual text will matter more than the launch of the review itself.
