6' high wall
   (B)   Required walls shall be located on the lot line except where utilities interfere and except in instances where this chapter requires conformance with front yard setbacks. Required walls may, upon approval of the Board of Appeals, be located on the opposite side of an alley right-of-way from a nonresidential zone that abuts a residential zone when mutually agreeable to affected property owners. The continuity of the required wall on a given block will be a major consideration of the Board of Appeals in reviewing such request.
   (C)   Such walls shall have no openings for vehicular traffic or other purposes, except as otherwise provided in this chapter and except such openings as may be approved by the Building Inspector. All walls herein required shall be constructed of materials approved by the Building Inspector, to be durable, weather resistant, rust proof and easily maintained; and wood or wood products shall be specifically excluded. Masonry walls shall be erected on a concrete foundation which shall have a minimum depth of 42 inches below a grade approved by the Building Inspector and shall not be less than four inches wider than the wall to be erected.
   (D)   The Board of Appeals may waive or modify the foregoing requirements where cause can be shown that no good purpose would be served, provided that in no instance shall a required wall be permitted to be less than four feet, six inches in height. In consideration of requests to waive wall requirements between nonresidential and Residential Districts, the Board shall refer the request to the Planning Commission for a recommendation. In some cases as the Planning Commission determines the Residential District to be a future nonresidential area, the Board may temporarily waive wall requirements for an initial period not to exceed 12 months. Granting of subsequent waivers shall be permitted, provided that the Planning Commission shall make recommendation as hereinbefore described, for each subsequent waiver prior to the granting of such waiver by the Board.
