Prince William County, Virginia
Prince William County is a half-million-person Northern Virginia market where data centers, Quantico Marine Corps Base, and the I-95 and I-66 commuter corridors drive absorption. The Prince William Digital Gateway and the Innovation Park area near Manassas are the large development stories, and power capacity, transmission routing, and contested rezonings are the main constraints.
