To ensure adequate planning and allocation of resources among jurisdictions in the National Capital Region, the Federal Homeland Security Act of 2002 established the directorate of National Capital Region Coordination for Emergency Response within the U.S. Department of Homeland Security. That region includes Maryland, Virginia, the District of Columbia, seventeen local jurisdictions, regional authorities, and private companies responsible for critical communication and electrical infrastructure.
Geographically, the National Capital Region was defined by the National Capital Region Planning Act of 1952 as the District of Columbia, two Maryland counties, and four Virginia counties. The Maryland components are Montgomery and Prince George's counties, and the municipalities of Bowie, College Park, Gaithersburg, Greenbelt, Rockville, and Takoma Park. In Virginia, Arlington, Fairfax, Loudon, and Prince William counties are included, as are the cities of Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park.
