(a) Screening of Uses in Particular Districts. The development standards for particular districts require the installation of landscaped "buffer" areas of those side or rear yards that are adjacent to districts where single or two-family residences are permitted uses. When required, such screening shall consist of walls, landscaped earthen mounds, fences, natural vegetation or an acceptable combination of these elements, provided that screening must be at least seven (7) feet in height. The use of year-round vegetation, such as pines or evergreens, is encouraged. Landscaped screening shall have at least seventy-five percent (75%) opacity during full foliage.
(b) Screening of Trash Receptacles. The development standards for particular zoning districts require the screening of trash receptacles to effectively screen them from view. In those cases where screening is required, landscaping can be utilized to meet the requirement, provided the standards for such landscaping meet the requirements of subsection (a) hereof.
(c) Maintenance of Shrubbery and Hedges. In any district, no shrubbery or hedge shall be planted, in such a manner that any portion of growth extends beyond the property line. The owner or occupant of property on which there is shrubbery, hedges, or trees located so as to affect the vision of drivers on adjacent streets shall keep shrubbery and hedges trimmed to a maximum of thirty (30) inches in height, and keep trees trimmed so as to avoid covering or obscuring of traffic visibility or traffic control signals.
