Wherever a greenbelt is required, it shall be made fertile and be planted within six (6) months from the date of issuance of a permit for use, and thereafter reasonably maintained with permanent materials to provide a suitable screen from adjacent properties in conformance with the following standards:
(A) Minimum planting width shall be three feet (3').
(B) Plant materials, if adjacent to a fence line, shall not be placed closer than four feet (4').
(C) Plant materials shall be in sufficient density and height to provide for an effective screening of view on a year round basis from adjacent properties. A mixture of evergreen and deciduous plant materials which would include between twenty percent (20%) and forty percent (40%) evergreen is suggested. (Ord. 567, 11-1976)
