The purposes of the USN zone are to:

  • Implement the Comprehensive Plan by ensuring that development of the air rights is not inconsistent with the goals and policies of the Comprehensive Plan including:
    • Creation of a catalytic development that would provide an active streetscape connection between neighborhoods west of the railroad tracks and east of the railroad tracks;
    • Infill of an underutilized property near a multi-modal transportation hub with the provision of a mix of high density commercial and residential uses; and
    • Preservation and enhancement of Union Station, and general economic development of the North of Massachusetts Avenue (NoMa) area and the District of Columbia;
  •  Reconnect the District of Columbia by creating an urban fabric that will reconnect the H Street commercial corridor to the east, North Capitol Street to the west, NoMa to the north and west, and Union Station to the south;
  • Provide a suitable visual relationship to surroundings by ensuring the provision of exemplary architecture for any building in the USN zone, and encouraging upper story setbacks and minimized penthouses;
  • Improve the character of H Street by establishing H Street, N.E., between 1 st and 2nd Streets, N.E., as an attractive, active, pedestrian-oriented street with active ground floor uses and a varied façade;
  • Utilize transportation infrastructure by facilitating development that would take advantage of Union Station’s unique combination of local, regional and national investment in pedestrian, bicycle, rail transit, bus transit, and intercity rail infrastructure, and ensuring that development complements and allows the expansion and enhancement of the transportation infrastructure;
  • Establish a mix of uses throughout the USN zone including residential and retail, as well as office, hotel, and other permitted uses; and
  • Create a walkable environment by requiring suitable ground floor uses, appropriate building design and appropriate site layout, including wide sidewalks.
