You're probably familiar with the sight of a long, quiet residential street unadorned by sidewalks, pushing pedestrians, pets, and kids on bikes onto the street. Is there ever a good reason for such a typology?

The questions comes as Washington D.C. and other cities are retrofitting some residential neighborhoods with sidewalks.
The post poses the question to a group of experts—contributors to Greater Greater Washington—for their opinion on the matter. The article provides a lot of good data, well-considered opinion, and historic background on why some residential neighborhoods lack sidewalks.
