Federal Relocation Arc
The Federal Relocation Arc is a network of facilities surrounding Washington, D.C. designed to ensure the survival of non-military components of the United States government in the event the capital city of Washington is rendered uninhabitable during a war or other serious emergency, such as a nuclear attack. Departments participating in the Federal Relocation Arc are primarily agencies that might not themselves be military targets but could have their operations disrupted should a serious event occur in the capital.
