Planning commission recommends denial of proposed substation for by‑right data‑center development, citing noise and transmission‑line impacts

The Culpeper County Planning Commission voted to recommend denial of a conditional use permit for a proposed electrical substation on a heavy‑industrial parcel off Bennett Road and James Madison Highway. The application, filed by MBCPCIP 2 LLC (manager Daniel Woodford), would support a by‑right data‑center development the applicant described as a prospective end use, but the applicant had no end user committed at the time of the hearing.

Staff summary and concerns: Planning staff noted the proposed 600‑by‑400‑foot substation pad lies within a wooded portion of the parcel but is close to existing commercial uses and to a row of residences; staff measured the closest house to be roughly 600 feet from the pad and identified a line of houses within about 520–600 feet. Staff flagged potential impacts on the adjacent floodplain and said transmission lines to serve the substation could create significant impacts on other landowners depending on the route chosen.

Public and organizational comment: Residents and advocacy groups urged denial. Laura Rogers (Stevensburg) said the applicant had not identified an end user or the transmission‑line route and recommended denial because the county could not evaluate health and safety impacts without those details. The Piedmont Environmental Council warned that substation transformers can produce continuous noise — including low‑frequency sound — that in rural areas can be perceptible more than 1,000 feet from the source and cause sleep disturbance and other health effects; the council also noted national transformer shortages could delay energizing new substations by years.

Applicant response: Daniel Woodford said the applicant is engaging power consultants and Dominion to identify feasible transmission‑line routes and offered potential low‑impact routing options that would use existing line corridors where possible; he said screening berms and vegetation could reduce visual impact. Woodford said the developer would build a substation in coordination with an eventual data‑center partner rather than ahead of a contract.

Why it matters: Commissioners and residents framed the project as emblematic of larger, county‑wide questions about where and how to site data centers and their supporting infrastructure — particularly transmission lines — and noted the county has not adopted an ordinance to direct where data centers may be built.

Action: The commission moved to recommend denial, finding the application was not substantially in accord with the comprehensive plan and raising concerns about impacts to health, safety and welfare from noise and potential transmission‑line expansion. The recommendation will be forwarded to the Board of Supervisors for final action.
