1141.07 SUPPLEMENTARY YARD REGULATIONS.
   Yards may be used for off-street parking, loading, traffic circulation, illumination, landscaping and signs as regulated in other sections of the Zoning Code.
   (a)   Front Yards. Front yards for buildings and uses shall not be less than established in Section 1141.06 and no structures shall be erected in front of such line unless shown otherwise on the Zone Map or specifically modified in supplementary regulations. If parking is permitted in front yards, a concrete curb shall be erected along the parking area and the yard between such curb and the public right-of-way shall be landscaped and maintained attractively.
   (b)   Side Yard on Corner Lots. Whenever an office building is located on a corner lot, the width of the side yard on the side street shall be not less than seventy-five feet for major arterial streets, fifty feet for collector streets and thirty-five feet for local collector and local streets. On a corner lot, parking shall be set back at least twenty feet from the side street right-of-way.
   (c)   Yard Screening and Landscaping. Whenever an office building is located on a lot which adjoins a Residential District, a side and/or rear yard of not less than that set forth in Section 1141.06 shall be provided on the office building lot. A fifty foot wide area buffer within any such rear or side yard, running parallel with adjoining residential lot lines, shall further be required and this fifty foot shall be landscaped and maintained in such a way as to provide a visual and noise barrier for the adjoining residential property. The Planning and Design Commission may, however, vary the width requirement of this required buffer area, if the depth or configuration of a lot renders the strict compliance with this provision impractical.
      Visual screening, such as earth mounding or walls or fences or landscape planting, shall be a required site improvement element for any office building use adjacent to any Residential District. The type and arrangement of such screening shall be as approved by the Commission.
      A minimum of ten percent (10%) of the area of all offstreet parking areas shall be allocated to landscape improvements.
