   A.   Trees on or within the city property shall at all times be so trimmed and pruned that there shall be at least seven and one- half feet (71/2') of clear space between the surface of the sidewalk or parkway, as the case may be, and the overhanging branches and leaves, and so that there is at least thirteen feet (13') of clear space between the surface of the roadway and the overhanging branches and leaves.
   B.   The branches or leaves of any tree, which overhang any sidewalk, parkway or roadway present in such manner as to create a hazard to, or impediment to the progress or vision of any person traveling on any street, sidewalk or roadway, or which covers, endangers or impairs the view of any traffic control device by a person operating a motor vehicle on a roadway, including any branches or leaves within the restricted areas mentioned in subsection A of this section, are hereby declared to be a public nuisance, whether or not within the restricted areas mentioned in subsection A of this section.
   C.   Each owner of property abutting on a street shall at all times keep pruned and trimmed all trees on his property which abut this property so as at all times to prevent such branches and leaves from protruding within the restricted area mentioned in subsection A of this section and from constituting a public nuisance under subsection B of this section. Each owner of property shall also treat or remove any tree or plant so diseased or insect ridden as to constitute a hazard to trees or plants in public places.
