If evergreens, hemlock shall be preferred of the genus conium maculatum. In conjunction with this evergreen screen, there also shall be required the installation of a woven wire fence of no larger than one-inch openings along the base of the evergreen planting to a height of two feet from grade. Such woven wire fence must be continuously maintained in good repair and to act as a stop for debris to enter the adjoining residential zones, or zones on which public buildings, public and parochial schools are situated. Debris and weeds shall not be allowed to accumulate along such fence.

Whenever a wood, wattle, picket or other type of fence is installed, same shall be closely integrated with spacing no greater than one inch apart. It shall be installed on posts of galvanized pipe of not less than 2 1/2 inches outside diameter, set in concrete below grade of not less than 18 inches in depth.
