One of my clients has a beef with the city, they dug a trench to install a sewer line way past his property line without permission and severed the roots to a approx5' dbh sugar maple. It forks into two leaders fairly low and one side had been butchered by his neighbor earlier. The remaining side however was still in good shape and provided a substantial canopy and served as an excellent windbreak for the rest of his property. The city is offering to remove the tree for free but that is the extent of it. He wants to sue the city for the value of the tree. Besides yhis being an overmature sugar maple and the fact that it was severely topped on one side( as in cut about 15' up the trunk, just past the first fork with a couple of 2'stubs) I can see a value as far as it being a windbreak , If this tree were any closer to a dwelling or even his yard I would consider it more of a liability than anything else. Anybody have experience with this type of issue?
