1286.05 COMPUTATIONS AND RULES OF MEASUREMENT.
   The following regulations shall control the computation and measurement of sign area, sign height, window area and building frontage:
   (a)   Determining Sign Area or Dimension.
      (1)   Sign area shall include the face of all the display area of the sign. Sign area shall not include the frame and structural support unless such structural support is determined to constitute an integral part of the sign design.
      (2)   For a sign that is framed, outlined, painted or otherwise prepared and intended to provide a background for a sign display, the area of the sign shall be the area of one (1) rectangular shape that encompasses the entire background or frame.
      (3)   For a sign comprised of individual letters, figures or elements on a wall or similar surface of a building or structure, or an irregular shaped freestanding sign, the area of the sign shall be the area of one (1) rectangular shape that encompasses the perimeter of all the elements in the display.
      (4)   For freestanding signs and projecting signs:
         A.   The sign area shall be computed by the measurement of one (1) of the faces when two (2) identical display faces are joined, are parallel, or within thirty (30) degrees of being parallel to each other and are at no point separated by a distance that exceeds two (2) feet apart.
         B.   No more than two (2) display faces shall be permitted.
         C.   The portion of a solid sign base that is mostly screened by landscaping, up to a maximum height of two (2) feet, shall not be calculated as sign area.
   (b)   Determining Sign Height. The height of a sign shall be measured from the average natural grade at the base of the sign or support structure to the tallest element of the calculated sign area. A freestanding sign on a man-made base, including a graded earth mound, shall be measured from the average site grade prior to the addition of the sign.
   (c)   Determining Building Frontage and Building Unit. For the purposes of these sign regulations, the length of the building wall that faces a public street, that faces a public parking lot, or that contains a public entrance to the uses therein shall be considered the building frontage. See subsection (c)(5) and (6) below.
      (1)   Each building frontage shall be entitled to the sign area permitted in this Chapter.
      (2)   The building frontage shall be measured along such building wall between the exterior faces of the exterior side walls.
      (3)   In the case of an irregular wall surface, a single straight line extended along such wall surface shall be used to measure the length.
      (4)   For multi-occupant buildings, the portion of a building that is owned or leased by a single occupant shall be considered a building unit. The building frontage for a building unit shall be measured from the centerline of the party walls defining the building unit.
      (5)   The primary frontage shall be the portion of a frontage that serves as the main access point to a building or building unit. A site/building will be considered to have secondary frontage when any of the following site/building characteristics are present:
         A.   The subject site is a corner lot;
         B.   The primary parking area is not located adjacent to a public street; and,
         C.   The building or unit has walls with ingress and egress that do not face the public street.
      (6)   When a site has primary and secondary frontage as defined in subsection (c)(5) hereof, the property owner shall determine which wall shall be the primary building frontage and which wall(s) shall be the secondary building frontage. Only one (1) outside wall of any business shall be considered its primary frontage.
   (d)   Determining Window Area. The window area of a building shall be the total glass area of windows on the building frontage. For the purposes of determining window area for ground floor occupants, the ground floor shall be considered to be no more than fifteen (15) feet in height above grade.
