AWS, QTS, and JK Land Holdings planning data center developments in Virginia’s Prince William CountyData Center...
The December 2022 trade report describes QTS’s planned expansion at 10680 University Boulevard, adjacent to its existing Manassas campus. The county’s later planning record identifies the same property and planning case as DC-4 PRA, so the report is retained as project-area context rather than as a precise permit-size source.
