Perimeter Security at the National Museum of American History
(File Number 6423/6636)

The Commission approved final site development plans for perimeter security at the Smithsonian Institution’s National Museum of American History. The museum is located on the National Mall and Constitution Avenue, NW between 12th and 14th Streets.

In its approval the Commission recommended that the Smithsonian consider incorporating foundation plantings in the area between a south terrace balustrade and 24 inch freestanding site walls located within the Madison Drive building yard. The Commission also recommended that the Smithsonian submit for review and approval any existing signs that are relocated and any new signs.

The perimeter security design uses a variety of security measures including site and balustrade walls, cable-reinforced fences, benches, and fixed and retractable bollards.
Site walls, balustrade walls, and benches will be clad in stone to match the existing building veneer or terrace pavement.
• A cable-reinforced fence system will be concealed within dense, evergreen shrubs.
• Fixed and retractable 8 inch-wide and 31 inch-high bollards will be sheathed in dark gray stainless steel and spaced approximately 5 feet apart at all pedestrian and vehicular entrances. The fixed bollards will be located in the entrance walkways and passageways into the site, and retractable bollards will be placed across the semi-circular driveway openings.
• Guardhouses shall be located adjacent to the existing employee and service drives, and will have flat, copper-roofs, stone base panels, and windows on all four sides.
The majority of the barrier line is still at the building yard’s edge along Constitution Avenue, NW, 12th and 14th Streets, and is within the building yard along Madison Drive, facing the Mall.

First Stage Planned Unit Development and Map Amendment for George Washington University Campus Master Plan
(File Number Z.C. 06-12)

The District of Columbia Zoning Commission submitted to NCPC for review and comment a proposed action for a first stage Planned Unit Development (PUD) and zoning map amendment in conjunction with George Washington University’s 2006-2025 Campus Plan. This PUD for the Foggy Bottom campus identifies use and massing for 16 development sites located on 10 of the university’s 20 squares.

NCPC reviewed the proposal for its impact on federal interests, which include numerous original L’Enfant streets and reservations, the Height of Buildings Act of 1910, the Foggy Bottom Metrorail Station, and adjacent historic resources.

The Commission determined that the first stage PUD will not have a negative impact on the federal interest. The Commission recommended that the Zoning Commission approve the first-stage PUD but require that George Washington University demonstrate consistency with the Height of Buildings Act of 1910 in the Campus Plan (Condition 6.b) for approval of each second-stage PUD. Condition 6.b currently states that the height, bulk, and design of each submission will be compatible with adjacent structures but does not mention the Height of Buildings Act.
