Federal Agencies

The Department of Defense, the Department of the Interior, and the General Services Administration are the largest federal landholders in the National Capital Region and submit many of the development plans and projects that are subject to NCPC review. The heads of these agencies  are ex officio members of the National Capital Planning Commission. These and other federal agencies also contribute advice and expertise to NCPC’s physical planning initiatives. Many are listed below, with a brief description of their role in the planning process and the main points of intersection with NCPC.

Architect of the Capitol (AOC)
AOC develops, maintains, and operates the buildings and grounds of the Capitol complex. This includes the Capitol and its Visitor Center, the House and Senate office buildings, the Library of Congress, the Supreme Court, the U.S. Botanic Garden, and other facilities. AOC plans and projects are not subject to NCPC review. AOC has been working with NCPC, the U.S. Commission of Fine Arts, the District of Columbia, and the National Park Service since 2007 to ensure that the Capitol Complex Master Plan complements other major planning visions for the development of central, Washington, DC.


General Services Administration (GSA)
GSA’s Public Building Service is one of the largest federal landholders in the National Capital Region. It manages the design, construction, and renovation of federal facilities, and NCPC reviews many GSA-submitted projects each year. The Administrator of General Services is an ex officio member of the Commission. GSA worked closely with NCPC on the Interagency Security Task Force, the NY/Florida Ave Charrette, the Transportation Management Plan Handbook, and Reimagining the Federal Superblock.

National Park Service (NPS)
NPS is part of the Department of the Interior and is one of the largest landholders in the National Capital Region. It maintains many of the capital’s landmarks and parks, including the National Mall. NCPC has provided advice and expertise to NPS’s National Mall Plan, and the Park Service has been a key contributor to the Interagency Security Task Force and the Monumental Core Framework Plan. It is a partner, along with NCPC and the government of the District of Columbia, in the CapitalSpace park planning initiative.

Smithsonian Institution (SI)
SI is the largest museum complex and research organization in the world, with several landmark facilities along the National Mall and in downtown Washington, DC. SI has created several exemplary perimeter security systems that are consistent with the recommendations of NCPC’s National Capital Urban Design and Security Plan and subsequent policies.  SI has also contributed substantial input into the Monumental Core Framework Plan.

U.S. Army Corps of Engineers (USACE)
The U.S. Army Corps of Engineers is responsible for a wide variety of infrastructure projects, including those related to the management of water resources, ecosystem restoration, and disaster response. USACE projects in the National Capital Region fall under the jurisdiction of the Baltimore District, which oversees the Washington Aqueduct, helps restore the Chesapeake Bay, and prepares military installations for BRAC-related conversion to other uses. The Corps is responsible for many of the improvements to the National Mall (Potomac Park) Levee.
