If a tree limb is dead, endangering overhead wires, or is otherwise a threat to the safe use of your property, you can have the limb(s) removed in some circumstances. You should speak to your neighbor first before having any limbs cut. You should not attempt to cut limbs yourself near overhead wires, you cannot prune a limb beyond your property line without your neighbors permission, and you should not aggressively prune a tree so as to severely disfigure or kill the tree. The Town will not intervene in nuisance tree issues unless the tree is within a Town right-of-way or open space.
