Local votes and rules
📜 Data center rules
After a meeting that ran past 2:30 a.m., supervisors voted 4-2 (one abstaining) to require data center buildings to sit at least 750 feet from homes, schools, and the Rappahannock and Potomac rivers, up from 100 feet. County staff called it the strictest setback in Virginia.
