A. Sign area shall be measured as follows:
1. Sign copy mounted on or painted on a background panel or area distinctively painted, textured, or constructed as a background for the sign copy shall be measured as that area contained within the sum of the smallest rectangles that will enclose both the sign copy and the background.
2. Sign copy mounted as individual letters or graphics against a wall, fascia, mansard, or parapet of a building or other structure that has not been painted, textured, or otherwise altered to provide a distinctive background for the sign copy shall be measured as a sum of the smallest polygon of not more than 12 sides that will enclose each word and each graphic in the total sign.
3. Signs with multiple faces shall be measured as follows:
a. The area of all faces shall be included in determining the area of the sign, except that only one face of a double-faced sign shall be considered in determining the sign area when both faces are parallel and the greatest distance between faces does not exceed five feet, or when the interior angle of the sign faces does not exceed 45 degrees in the case of a ‘V’- configured sign. If the area of one sign face exceeds the area of the sign’s opposing face, the area of the larger face shall be used to determine the sign area.
b. The area of a sign that contains three or more faces shall be calculated as 50% of the sum of the area of all faces.
c. Spherical, free-form, sculptural, or other non-planar sign area is measured as 50% of the sum of the areas using only the four vertical faces of the smallest six-faced polyhedron that will encompass the sign structure.
B. Sign height shall be measured as follows:
1. The height of a freestanding sign shall be measured as the vertical distance from the finished grade beneath the sign, exclusive of any filling, berming, mounding or landscaping done solely for the purpose of locating the sign, to the highest point of the sign. If the sign is proposed in a location in which the finished grade beneath the sign is lower than the grade of the adjacent roadway surface, the sign height shall be measured from the top of the curb, or crown of the adjacent roadway surface where no curb exists. The height of any monument base or other structure erected to support or ornament the sign shall be measured as part of the sign height.
2. Wall fascia, mansard, and parapet-mounted signs shall be measured as the vertical distance to the top of the sign or sign structure from the base of the wall on which the sign is located.
