The situation
The largest protected natural area in the Washington region, 16,000 acres of Piedmont forest and the restored Quantico Creek watershed just off Interstate 95. In July 2026 a data center developer proposed swapping 73 acres of its wetlands for 36 acres of the national park to build four 100-foot data center buildings and a substation along the park boundary. The deal would push heavy industrial development, and its noise, light, and water demands, into one of the last large forests in fast-developing Prince William County.
