The NCPC board is reviewing the Zoning Commission's approval of the slew of Capper zoning changes that I wrote so much about earlier this year, some of which focus on these two new buildings on the old Capper Seniors site. The Executive Director's recommendation document (which provides some good background if you haven't been following along), refers to letters included in the document to the Zoning Commission from both the Navy and Marines stating that the new buildings on what's known as Square 882 "may pose a safety and security threat to the military personnel at both the Navy Yard and the Marine Barracks and that the there will be a visual impact on the Navy Yard Historic District."

Apparently the Navy, Marines, the DC Housing Authority, and Forest City (developers of 600 M) have tentatively agreed to a few steps to mitigate these concerns: the placement of surveillance cameras on the roofs of the proposed buildings, procedures for notifying the Navy and Marines when the roofs are to be accessed, review by the Marines and Navy Yard of tenants wishing to occupy the third through eighth floors of the 600 M office building, and a "window design to enhance security for Navy and Marines." (On this last point, the document says that "the Navy and Marines would request that the windows facing their sites not be operational," but I wonder how tenants in the proposed apartment building along L Street would feel if none of their windows could ever be opened.) The document says that memorandums of understanding between the housing authority and the Navy and the Marines should be able to be completed within the next few weeks.

Additionally, in its letter to the Zoning Commission, the Navy Yard mentions its belief that "buildings exceeding the currently permitted fifty (50) foot height restrictions located across M Street from the Navy Yard Historic District will negatively impact the view shed from the Navy Yard" and "could potentially compromise the integrity of the Washington Navy Yard Historic District, including the Latrobe Gate." It might be worth noting here that the old Capper Seniors building, built in the 1950s and demolished in 2007, was nine stories high, and so an uninterrupted "view shed" is not something that the Navy Yard has always enjoyed since its arrival in the neighborhood back in 1799.

The NCPC's reason for reviewing Zoning Commission cases in DC is to determine whether the proposed actions would have an "adverse effect" on federal interests, and, in this case, the NCPC staff is advising their commission to vote to advise the Zoning Commission that these Capper cases do indeed meet that "adverse effect" standard. Also, the NCPC staff is recommending that the Zoning Commission delay their final action on this case (scheduled for Monday, June 8) to allow the agreement described above to be finalized.
