Sign height is measured as follows:
(A) Freestanding signs. The height of a freestanding sign shall be computed as the distance from the base of the sign at finished grade to the top of the highest attached component of the sign. The height of any monument sign base or other structure erected to support or adorn the sign is measured as part of the sign height. If a sign is located on a mound, berm, or other raised area for the sole purpose of increasing the height of the sign, the height of the mound, berm, or other raised area shall be included in the height of the sign.
(B) Building mounted signs. The height of wall, fascia, mansard, parapet or other building mounted signs is the vertical distance measured from the base of the wall on which the sign is located to the top of the sign or sign structure.
