A. 
The sign area shall be determined by combining the area(s) of the smallest square, circle, oval, rectangle, triangle or combination thereof that will encompass the extreme limits of the sign face. The area of an oval shall be computed as 80% of the area of a rectangle with the equivalent height and width.
B. 
In computing the sign area of an individual sign that consists of more than one section, segment, part or module, the open area between such sections shall be included in computing the sign area.
A. 
Double-sided signs.
(1) 
Double-sided signs shall be regarded as one individual sign, provided all of the following requirements are met:
(a) 
The sign faces have identical graphics and wording;
(b) 
The angle of the "V" created by the intersecting sign faces does not exceed 45°; and
(c) 
The distance between the backs of the sign faces does not exceed 36 inches when measured at the point where the distance between the backs of the sign faces is the least.
(2) 
The area of a double-sided sign shall be the area of the largest single face only.
B. 
Multiple-sided signs. Multiple-sided signs shall be prohibited.
A. 
For wall signs, the entire building elevation, including windows and doors, for that side of the building shall be used in computing the maximum permitted sign area. See § 436-24, Definitions.
B. 
The maximum permitted sign area for a wall sign shall be dependent upon the numbers of stories and/or height of the building. The maximum permitted wall sign area shall be computed as follows:
(1) 
The maximum allowable sign area for a one-story building not exceeding 15 feet in height shall be 15% of the building elevation.
(2) 
The maximum allowable sign area for a two-story building not exceeding 30 feet in height shall be 10% of the building elevation.
(3) 
The maximum allowable sign area for a building exceeding 30 feet in height shall be 5% of the building elevation up to a maximum of 40 feet in building height.
