The 2 western blocks have alleyways, but on the 2 eastern blocks it looks like just an internal sidewalk. But there are maybe 5 or 6 private parking lots (including maybe a shared garage) on the 23rd Ave side for 40 or so additional parking spaces. This is in addition to the 12 spaces on the former cross street. Is this parking on former house lots, or maybe shared portions of reduced lots? There's possibly 2 or 3 more on the north end, unless these are exclusively for the Franklin Ave retail. Not sure if this affects your analysis.

I still prefer to not close streets completely to cars but rather to develop our techniques for severe control and restriction on them. Reduce the street to a single very narrow, very very slow (walking speed/ 3-5 mph), non-thru lane, while also preserving some parking. This keeps more constant human activity on the street/former street, and increases social safety. Sort of a green suburban woonerf.
