The area of every sign shall be calculated as follows:

    A.    If a two-dimensional sign is enclosed by a box or outline, the total area (including the background) within that outline shall be deemed the sign area.

    B.    If a two-dimensional sign consists of individual letters, parts or symbols, the area of the one imaginary square or rectangle which would completely enclose all the letters, parts or symbols shall be deemed the sign area.

    C.    In calculating two-dimensional sign area, only one side of any double-faced sign shall be counted.

    D.    The area of signs of unusual three-dimensional shapes, such as globes, cylinders or pyramids, shall be computed on the basis of the total allowable area of exposed surfaces. (Ord. 892 § 3-2, 1991)
