GSA, in cooperation with the U.S. Department of State (DOS) is preparing the Potomac Hill Campus Master Plan to guide the development of an 11.8-acre campus immediately west of the DOS headquarters (the Harry S Truman building, 2201 C Street, N.W.) in the downtown Washington, DC. . This important document will guide the future rehabilitation, renovation, and development of the site into a world-class federal facility envisioned to serve the long-term needs of the U.S. Department of State as an institution of American diplomacy.

Potomac Hill consists of two adjoining federally owned historic parcels known as Navy Hill and the Potomac Annex, located in the Foggy Bottom neighborhood. Both Navy Hill and the Potomac Annex Historic District have been determined eligible for listing in the National Register of Historic Places. The property also contains the original Naval Observatory, a National Historic Landmark as designated by the Secretary of the Interior. The Master Plan would provide GSA and DOS with a framework to guide the redevelopment of Potomac Hill into a unified federal campus that accommodates DOS’s operations and security requirements and recognizes the site’s historic character.

GSA historically has controlled Navy Hill and its three buildings (South, Central, and East) were occupied by DOS. In 2012, GSA acquired custody and control of Potomac Annex from the U.S. Department of the Navy (Navy) in order to accommodate additional DOS offices, as DOS does not have general authority to acquire real property in the United States. At this time the Potomac Annex buildings (Buildings 1-5) are undergoing renovation for use by DOS .

Today, Potomac Hill represents more a collection of buildings, pavement, and green space than a unified, functional federal campus meeting the modern needs of the government. The GSA Design Excellence process will create a Master Plan to meet DOS’s long-term space needs in a centralized government facility near DOS headquarters at a prominent historic site.
