   (b)   Required walls shall be located on the lot line except where underground utilities interfere and except in instances where the Zoning Ordinance requires conformance with front yard setback lines in abutting Residential Districts. Upon review of the site plan, the Planning Commission may approve an alternate location for the wall or may waive the wall requirement if in specific cases it would not serve the purposes of screening the parking area effectively. Required walls may, upon approval of the Board of Zoning 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 in reviewing such request.
   (c)   (1)   Such walls and screening barrier shall have no openings for vehicular traffic or other purposes, except as otherwise provided in the Zoning Ordinance and except such openings as may be approved by the Chief of Police and 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.
      (2)   Masonry walls may be constructed with openings which do not in any square section (height and width) exceed twenty percent (20%) of the surface. Where walls are so pierced, the openings shall be so spaced as to maintain the obscuring character required, and shall not reduce the minimum height requirement. The arrangement of the openings shall be reviewed and approved by the Building Inspector.
   (d)   The requirement for an obscuring wall between off-street parking areas, outdoor storage areas, and any abutting residential district shall not be required when such areas are located more than 200 feet distant from such abutting residential district.
 
   (e)   The Board of Zoning 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, except where Section 1187.06 applies.
      (1)   In consideration of request to waive wall requirements between nonresidential and residential districts, the Board shall refer the request to the Planning Commission for a determination as to whether or not the residential district is considered to be an area in transition and will become nonresidential in the future.
      (2)   In such 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 twelve months. Granting of subsequent waivers shall be permitted, provided that the Planning Commission shall make a determination as hereinbefore described, for each subsequent waiver prior to the granting of such waiver by the Board.
