If you haven’t heard of a “sneckdown” yet, it’s a clever combination of “snow” and “neckdown”—another name for a curb expansion—that uses snow formations on the street to reveal the space cars don’t use. Advocates can then use these sneckdown photos to make the case to local transportation officials that traffic-calming interventions like curb bump-outs and traffic islands can be installed without any loss to car drivers.
One of the areas of Philadelphia with the best opportunities for pedestrian plazas is East Passyunk Avenue, which crosses the street grid at a diagonal, creating lots of triangular intersections. I thought the snow would provide some good examples to help you visualize what I’m talking about, so I headed over there to take some sneckdown photos. And to my delight, the snow revealed some awesome traffic calming ideas I hadn’t considered.
At the intersection of 6th and Passyunk and Christian, near the excellent Shot Tower Coffee, there is a triangular plot of land that I always thought would make a great public plaza, but there’s a “for sale” sign there now, indicating it will probably become housing.
The city’s choice to allocate the public right of way around this triangle to curb parking for cars means the parcel is smaller than it could be, but even so, the snow formation shows it could be larger even without taking away parking. Try to imagine how much more sidewalk there could be if not for the curb parking around the island though:
Very thorough. This is a clever use of observational data: snow plowing makes the point that not all space on streets and roads is regularly used by cars. How might this space be used differently if it is not required as part of the road?
I wonder how much of this has to do with standards for road construction, whether in the past or today. For example, in Suburban Nation several New Urbanists argue that most road standards today are way too wide which then encourages faster driving and limits sidewalks and public space. They also suggest that we make choices as a society about how we want roads to function: are they there to maximize vehicle efficiency and speed or are they streetscapes that can help cultivate social and civic life (which usually means toning down the emphasis on vehicles)?
