Theory from convo with : sidewalks can have lots of trees if there are no curb cuts (NYC) or if lots are wide (PDX), but narrow lots + curb cuts = fewer sidewalk trees, bc too many long segments with little room bw curb cuts (common in SF!)
True? Relevant literature?

e.g: This is my street. At one end, there are no trees at all, because there are 6+ consecutive driveways across multiple lots on each side of the street! Not cute. But then, immediately after those lots, the situation improves, and the street's vibe is totally different!

There are plenty of counter examples even in SF (Cole Valley, Ashbury Heights, etc). Onus of street tree planting/maintenance being on homeowner, overhead power lines, economic status also play roles.

Relatively recent (2016) transfer of responsibility to Public Works, and so far they seem to be focused on cutting down trees (no data, just what I see).

A perhaps partial counterexample is New Orleans, where neighborhoods with narrow long houses, driveways, and trees for shade are not that uncommon. Maybe because long narrow houses leaves more space for trees on side streets, and houses often front onto green meridians?

This article is great: spur.org/publications/u
"Curb cuts often preclude trees, curbs, and parking, exposing pedestrians to traffic and preventing the definition of a distinct pedestrian space."
