There are two or more evergreens with a base that encroach the sidewalk. It's overgrowth is very sever forcing walkers to single file through. What is the township ordinance on this matter? There are other locations where a report and action could be helpful. I'm curious in how to proceed when conditions exist and corrective action is desired. Thank you. I am asking that action be taken for this property if this is an appropriate forum.
