The area of a sign with multiple display surfaces is the sum of the display surface areas.
(b) Notwithstanding subsection (a) of this section, if two display surfaces on the same sign are parallel and facing opposite directions, and the distance between the two surfaces is not more than two feet, then only the area of one of the two display surfaces is included in the computation of the sign's area.
