The CC District shall be permanently screened from adjoining and contiguous residential districts and service areas shall be screened from view from any abutting roadway, by a wall, fence, evergreen hedge, and/or other suitable enclosure of a minimum height of five feet and a maximum height of seven feet, placed at least 10 feet inside the CC District property line. However, along each side or rear property line which directly abuts and residential boundary line, a buffer area of not less than 15 feet in width shall be provided and which shall be placed a wall, fence, evergreen hedge and/or other suitable enclosure of a minimum height of five feet and a maximum height of seven feet to constitute an effective screen. The area between such enclosure and the property line shall be landscaped to form a permanent screening area. The Planning Commission may waive the requirement for a screening enclosure and/or screening area if equivalent screening is provided by earthen berms, existing parks, parkways, recreational area or by topography or other natural conditions.
