        b.    Screening buffer adjacent to residential zone:

            1.    Permanent screening consisting of a masonry wall, earth berm, wood fence, landscape materials, or combination thereof, at least eight (8) feet in height and not to exceed twelve (12) feet in height shall be required where a lot in this district abuts residentially zoned land. The required screening shall have an opacity of at least eighty (80) per cent year around and, if landscaping is used, the eighty (80) per cent opacity shall be achieved within four (4) full growing seasons. In the event a masonry wall or wood fence is used, ornamental landscaping shall be placed between the wall or fence and the property line. The required screen shall be placed within five (5) feet of the property line. In the front yard, the required screen shall not exceed three (3) feet in height.

            2.    Required walls, fences or landscaping shall be maintained in good order and not allowed to exist in a state of disrepair or death. If wood fencing is used, it shall be durable in nature or treated to prevent rapid deterioration.

            3.    Where exterior storage screening is located (as required by this chapter), adjacent to residentially zoned land and no other improvement exists, including parking, between the required exterior storage screening and the common property line with the residentially zoned land, the screening buffer adjacent to a residential zone may be waived by the commission. However, the commission shall not waive this requirement unless provisions are made at the time of approval of the screening plan that a continuous screen be provided where the tract abuts the residentially zoned land.

        c.    Screening requirements for exterior storage

            1.    All exterior storage areas shall be enclosed by a permanent screen at least eight (8) feet in height above the ground surface of the storage area. Required screening shall be constructed in such a manner and with such materials as may be approved by the commission. In the event that an eight-foot screen is inadequate to screen such an area, the commission may require additional screening in such a manner and of such materials as may be reasonably necessary to adequately screen such from public view. However, in no event shall the screen exceed twelve (12) feet in height, except for landscape materials. In no event shall the stored or stacked materials or finished products exceed the height of the required screening. The required screening shall have an opacity of at least eighty (80) per cent year around, and if landscaping is used, the eighty (80) per cent opacity shall be achieved within four (4) full growing seasons. When a solid wall, or any solid fence is used for screening, ornamental landscaping shall be placed between the fence and the adjacent property lines.

            2.    Exterior storage areas shall have a permanently dust-free surface.

            3.    No exterior storage of materials or finished products on property subject to this section is permitted except pursuant to and in compliance with a screening plan approved by the commission. Such plan shall state the location of buildings, proposed storage areas and proposed screening, setback dimensions from property lines, elevation(s) of proposed screening including building materials; and shall state colors, height, and any other information the commission may require.

            4.    The required screening shall be maintained in good order and not allowed to exist in a state of disrepair or death. If wood fencing is used, it shall be durable in nature or treated to prevent rapid deterioration. Failure to maintain the required screening shall be considered a violation of this chapter.
