Sidewalk Inspector

This morning I spoke with a gentleman named Mauna a City of Minneapolis Sidewalk Inspector. He too tried to explain it to me that "We the homeowners" are responsible for the sidewalks that the trees that the City Plant in the Boulevards and Sidewalks. They just plant them and then tell us, but actually DON'T tell us that we are responsible for the damages that the trees cause. He told me that He was not the person that I need to complain to, that is the Parks Department. However the Parks Department tell me that they are not the ones to complain to either. City Ordinance 247.90 states that we are responsible for the sidewalk damages due to the trees planted by the City Parks Department.
