   (b)   No person shall excavate any ditches, tunnels, trenches, or lay any drive within a radius of ten feet from any public tree or street trees, without first obtaining a written permit from the Service Director.
   (c)   Wherever it is necessary to remove a tree or trees from a Tree Lawn in connection with the paving of a sidewalk, or the paving or widening of the portion of a street or highway used for vehicular traffic, the City shall replant such trees or replace them with similar size trees, if practicable.
   (d)   No person or property owner shall remove a tree from the tree lawn for the purpose of construction, or for any other reason, without first filing an application and procuring a permit, and without replacing the removed tree or trees.  The Service Director can deny a permit if the removal of the trees is not necessary for the protection of the public health and safety.  Such replacement shall meet the standards of species, and placement as provided for in this ordinance and the Tree Plan.  Any removed tree with a DBH of four inches or more, shall be replaced with an approved tree of at least four inches DBHs.
