All plant and nonplant material shall be installed in accordance with the following standards:
(a) Maintenance-Free Nonplant Material. All nonplant material shall be durable and as maintenance-free as reasonably practical.
(b) Plant Quality. Plant and grass materials used in compliance with the provisions of this Zoning Code shall conform to standards of the Michigan Association of Nurserymen and shall have passed any inspections required under State regulations. Grass shall be clean and free of weeds and noxious pests or diseases.
(c) Plastic Plant Material Prohibited. Plastic and other nonorganic plant materials shall be prohibited from use and shall not be in compliance with the spirit or intent of this Zoning Code.
(d) Deciduous Trees. Deciduous trees shall be species having an average mature crown spread of greater than fifteen feet in Oakland County and having trunks which can be maintained with over five feet of clear stem, if conditions of pedestrian and vehicular traffic visibility require, except, however, at intersections where the requirement of eight-foot clear stems shall be followed. Trees having an average mature crown spread of less than fifteen feet may be substituted by grouping the same so as to create the equivalent of a fifteen-foot crown spread. Deciduous tree species shall be a minimum of ten feet in overall height and a minimum caliper of two and one-half inches at the point on the trunk, six inches above the ground immediately after planting.
(e) Ground Covers. Ground covers used in lieu of grass in whole or in part shall be planted in such a manner as to present a finished appearance and reasonably complete coverage after one complete growing season.
