9.7.1.2   Computation of Signage Area
   (A)   Computation of Height
      The height of a sign shall be measured from the highest point of a sign or its support whichever is greater, to the base of the sign at the highest adjacent grade. If said sign is placed in raised planter box or on a berm exceeding a 3/1 slope the base of the planter box or berm shall be used to determine height.
   (B)   Computation of Sign Face
      (1)   The area of a sign face shall be deemed to be the entire rectangular area within the smallest polygon that will encompass the extreme limits of the writing, representation, emblem, or other display on the sign that can be reasonably calculated. (See diagram below.)
      (2)   Individual channel letters or free-floating elements shall be measured as individual elements. The area shall also include any material or color forming an integral part of the background of the display is used to differentiate the sign from the backdrop or structure against which it is placed.
      (3)   Frames or structural members not bearing informational or representational matter shall not be included in computation of the area of a sign face.
      (4)   Signs attached to walls or fences shall be treated as monument signs and allowed only where monument signs are permitted. Only that portion of that wall or fence onto which the sign face or letters are placed shall be calculated in the sign area.
   (C)   Computation of Setback
      Unless specifically stated otherwise, setbacks are measured from the nearest point on the sign to the nearest point on a property line, right-of-way, easement, zoning boundary, use, or structure, as appropriate.
