Loudoun County has added information requirements for developers seeking approval for data centers and other facilities expected to use at least 100 megawatts of electricity. Applicants must disclose projected power demand and serving substations, identify distances from homes and schools, and assess potential noise impacts within 500 feet of a proposed site.

Developers must also explain potential effects on water resources, farmland, parks, historic sites and forests. County officials said the information will help determine whether proposals comply with local development plans, zoning rules and noise regulations, and that the requirements apply to all current and future legislative land-use applications.
