Hey all, I have a place in South Philly with a slightly-above averaged size backyard and third floor deck. The neighbors behind me also have a good-sized backyard, but they have a huge (never tended or trimmed) tree whose branches are literally scrapping my deck railing. My lower backyard is constantly filled with leaves, branches and some kind of small berry that falls off the tree. I've tried contacting my neighbors but to no avail. Also, considering the state of the tree and the house itself, I seriously doubt they will willingly deal with it. I even offered to pay for the trimming, but still no reply. So do i have any recourse here? Would calling 311 help? Thanks!
