They planted these damn flowering pear trees much too close to the sidewalk. Sure, when they were saplings, there was no problem, but trees do have this annoying tendency to grow.
And, the low branches now hang over the sidewalks which puts them around 5' off the ground.
Trust me, I feel your pain. I have to mow under them daily. Most of problem trees were professionally planted and were to satisfy the area covenants.... come on man! Try mowing an area's commons sometime.... sheesh! I'm sure it all looked great when the area was new. Now most of the foliage is way over grown and looks bad as well as being a hazard. Not to mention the trash they dump on the sidewalks.....
