15.36.060: HEIGHT MEASUREMENT:
   A.   The height of all signs shall be measured from the top edge of the sign and/or support structure to the average finished grade of the ground below the sign and/or support structure, as shown below. If the sign is adjacent to a sidewalk or curb, the height shall be measured from the average top of sidewalk or curb.
   B.   The following shall apply to signs located within ten feet (10') of a sidewalk or curb:
      1.   If the sign is located on a mound or other raised area, any mounding more than one foot (1') in height will be added to the height of the sign. (For example, a 4 foot high sign structure located atop a 3 foot high mound will be considered to be 6 feet in height.)
      2.   If the sign is located in a depression or similar lowered area, up to one foot (1') in elevation will be deducted from the height of the sign. (For example, a 4 foot high sign located in a depression 2 feet lower than the adjacent sidewalk will be considered to be 3 feet high.) (Ord. 2552 § 1, 2004)
