Back in early July, The National Park Service (NPS) and the U.S. Secret Service (Secret Service) held a public open house on the joint-agency President's Park South Project. This project will redesign the park immediately south of the White House including E Street, N.W. between 15th and 17th Streets, Washington, D.C. E Street was closed after 9/11 and has never been reopened creating quite a barrier to cyclists (pedetrians can get through their OK, but on a bike it is a massive hassle). See earlier posts on this here, here and here.
The NCPC contest was non-binding (but it "informed" the process), and so the four new alternatives presented at the July meeting are very different from the ones in the NCPC contest.
Two of the alternatives (2 & 3) include a bicycle path along the southern edge of E Street and the two others (4 & 5) route bicyclists around the existing perimeter streets (15th Street, Constitution Avenue and 17th Street). The latter two do this to create an expanded viewing area south of the existing fence - the shaded purple area on the image below. [1 is the no build option]
I think it would be a shame if this project didn't include a space for a bike path on E Street. I don't see why they can't expande the viewing area and include the bike path - the two do not seem mutually exclusive. Isn't that what we have on the north side of the White House?
Anyway, if you'd like to comment to that effect, public comments are being accepted until September 12th at this website. Comment early and often.
