(a) Subject to the imposition of conditions pursuant to subsection (b) of this section, a permit to remove, trim or prune any parkway tree or plant may be issued where any of the conditions set forth in Section 12.08.040 are found to exist, or where, upon taking into account the size, shape, topography and existing trees upon the lot, the denial of the permit would create an unreasonable hardship on the property owner.
(b) A permit for a tree removal may be conditioned upon the replacement of the tree(s) onsite. Such replacement shall be subject to the provisions of the parkway tree guidelines including, but not limited to:
(1) Designation by the director of the size, species and location of replacement tree(s);
(2) An existing tree(s) onsite may be designated to serve as a replacement tree(s);
(3) Should the tree(s) designated as a replacement not survive for a period of at least two years, further replacement shall be required.
