Besides what other commenters said -- street trees have to be pruned. If ey're not maintained and cause damage, the ci can be sued. And their roots can destroy sidewalks, sewers, and nearby roads (depending on species, placement, etc.). Not saying I like the reasoning, but that's what the city says. Based on observing my neighbors, I have come to believe that as one gets older, one tends to cut down trees and put concrete in, as a way to reduce maintenance and general loose ends and possibility for trouble. The city is that tendency writ large.
