Short article on a program beginning in San Diego, Calif, where they are mapping all city sidewalks. They assume that there are 5,000 miles of them, because there are 2,500 miles of city streets … but they really don’t know.
Interestingly (or “amazingly”, if you are as cynical as I am) the City of Norman has already done this, at least for most of the city. I can’t, however, find a map though I saw it at the city’s presentation on the Comprehensive Traffic Plan. I did find this report, however, on progress expanding the sidewalk network. Progress on getting existing sidewalks ADA compliant as well.
Note, too, mention of creating a Railroad Quiet Zone from Acres St to Post Oak Rd. Some grade crossings are already compliant with what is needed, Duffy St being one. Next time you pass that way, note the medians and “four quadrant” gates.
