Balance public and private objectives by allowing adequate avenues for both commercial and noncommercial messages;
B. 
Allow signs to serve as an effective channel of communication while preventing visual clutter that will detract from the aesthetic character of the City;
C. 
Maintain and enhance the City's appearance by regulating the location, number, type, quality of materials, size, illumination, and maintenance of signs;
D. 
Restrict signs that may create a nuisance to nearby properties, violate privacy, or create hazards or unreasonable distractions for pedestrians or drivers;
E. 
Provide clear and unambiguous sign standards that enable fair and consistent enforcement; and
F. 
Ensure that the constitutionally guaranteed right of free speech is protected.
(Ord. 24-002 § 5 (Exh. A))

C. 
Registered Mark. The provisions of this chapter shall not require alteration of the display of any registered mark, trademark, service mark, trade name, or corporate name that may be associated with or incorporated into a registered mark, where such alteration would require the registered mark to be displayed in a manner differing from the mark as exhibited in the certificate of registration issued by the United States Patent and Trademark Office.

A. 
Measuring Sign Area. The area of a sign face includes the entire area within a single continuous perimeter composed of squares and rectangles that enclose the extreme limits of all sign elements, including, without limitation, sign structures or borders, written copy, logos, symbols, illustrations, and color. Supporting structures, such as sign bases and columns, are not included in sign area; provided, that they contain no lettering or graphics except for addresses. The area of an individual sign shall be calculated as follows:
FIGURE 18.18.050.A: MEASURING SIGN AREA
1. 
Single-Faced Signs. The sign area of a sign with a single face area is the area of the sign face.
2. 
Double-Faced Signs. Where two (2) faces of a double-faced sign are located two (2) feet or less from one another at all points, or located at an interior angle of forty-five (45) degrees or less from one another, the sign area of double-faced signs is computed as the area of one (1) face. Where the two (2) faces are not equal in size, the larger sign face will be used. Where two (2) faces of a double-faced sign are located more than two (2) feet or greater than forty-five (45) degrees from one another, both sign faces are counted toward sign area.
FIGURE 18.18.050.A.2: MEASURING SIGN AREA, DOUBLE-FACED SIGNS
3. 
Multi-Faced Signs. On a three (3) faced sign, where at least one (1) interior angle is forty-five (45) degrees or less, the area of two (2) faces (the largest and smallest face) must be summed to determine sign area. In all other situations involving a sign with three (3) or more sides, sign area will be calculated as the sum of all faces.
FIGURE 18.18.050.A.3: MEASURING SIGN AREA, MULTI-FACED SIGNS
4. 
Three (3) Dimensional Signs. Signs that consist of, or have attached to them, one (1) or more three (3) dimensional objects (i.e., balls, cubes, clusters of objects, sculpture, or statue-like trademarks), may have a sign area that is the sum of all areas using the four (4) vertical sides of the smallest rectangular prism that will encompass the sign.
FIGURE 18.18.050.A.4: MEASURING SIGN AREA, 3D SIGNS
B. 
Measuring Sign Height. The height of a sign is the vertical distance from the uppermost point used to measure sign area to the existing grade immediately below the sign.
FIGURE 18.18.050.B: MEASURING SIGN HEIGHT
C. 
Measuring Sign Clearance. Sign clearance shall be measured as the smallest vertical distance between finished grade and the lowest point of the sign, including any framework or background embellishments.
FIGURE 18.18.050.C: MEASURING SIGN CLEARANCE
(Ord. 24-002 § 5 (Exh. A))
