Sec. 20.184.045 - Computing Sign Area and Height.

(A)

Allowable sign area which is determined by the amount of street frontage shall be based on the total of all street frontages for the lot or parcel, as shown in Figure 20.184-A below.

Figure 20.[184]-A—Sign Area Frontage

(B)

The area of a sign is computed by multiplying the height by the length of the sign, not including any framework which is not part of the sign. For signs whose shape is a regular geometric figure (square, rectangle, circle, etc.), the area shall be calculated using standard formulas (Height x Width for a rectangle, etc.).

(C)

Where a sign contains a frame, background, or other material used to differentiate the sign from the background on which it is placed, the sign area shall be measured to include the entire frame, background, or other material.

(D)

For signs whose shape is irregular, such as individual letters placed on a wall or a monument sign, the area shall be measured by enclosing the sign elements within up to eight (8) straight, intersecting lines, as shown in Figure 20.184-B below.

Figure 20.[184]-B—Irregular Sign

(E)

The base or supporting structure of a sign is not considered part of the sign unless it is part of the message presentation.

(F)

The area of a two-sided back-to-back sign shall be computed by determining the area of only one (1) side if the two (2) sides are within forty-five (45) degrees of parallel and not more than three (3) feet apart. Where the sign faces are at an angle of forty-five (45) degrees or more, or more than three (3) feet apart, area shall be computed by multiplying the height by the length of each sign face and adding the results (area of Face A + area of Face B).

(G)

Time and temperature displays are considered part of the allowable sign display area and are subject to the same size and height rules as other aspects of a sign.

(H)

For establishments providing services to customers while in their vehicles, signs related to such services are allowed, but are counted in the aggregate allowed signage for the use. Drive-through establishment menu boards shall not be included in this calculation.

(I)

Measuring Sign Height. The height of a sign is the vertical distance from the uppermost point used to measure sign area to the average finished grade of the ground below the sign and/or support structure, as shown in Figure 20.184-C below.

(Ord. No. 4538, § 48(Exh. A), 9-10-2024)
