11-41-7: - STANDARDS OF MEASUREMENT
A. Sign Area Measurement. Sign area for all sign types is measured as follows:
1. Sign copy is measured as a minimum area contained within the sum of one (1) or two (2) smallest tangent rectangle(s) or other standard regular geometric shapes (e.g.: circle, triangle, regular ellipse, regular rhombus or regular parallelogram), or combination of rectangles or standard regular geometric shapes (e.g.: rectangle and circle, two (2) triangles, or a circle and a rhombus) that will enclose both the sign copy and the background, as shown in Figure 11-41-7-A. When two (2) shapes are used, the shapes must include at least one (1) point of common tangency between the two (2) shapes.
2. The background portion of a sign is included in the sign area measurement when the surface of a building or background panel to which the sign copy is mounted, affixed, painted, or textured, is clearly distinct when compared to the color, texture, or materials used on the building or mounting structure.
3. A sign as individual letters, logos, or similar graphics painted or mounted directly on a wall, fascia, mansard, or parapet of a building or surface of another structure are measured based on the calculation described in Section 11-41-7-B that encloses the entire proposed sign in total, as shown in Figure 11-41-7-B.
4. Sign copy mounted, affixed, or painted on a distinct illuminated surface or illuminated element of a building or structure is measured as the entire illuminated surface or illuminated element that contains sign copy, as shown in Figure 11-41-7-A.
5. Window sign area is computed by calculating each windowpane or panel. A group of windowpanes or panels is considered one (1) window if the windowpanes or panels are adjoined or are not separated by more than six (6) inches. The area for each building face and window is separate. The building face includes any doors or walls with varying wall planes.
6. A multi-face sign, as shown in Figure 11-41-7-D, is measured as follows:
a. Two (2) face sign:
i. If the interior angle between the two sign faces is forty-five (45) degrees or less, the sign area is one (1) sign face only. If the angle between the two (2) sign faces is greater than forty-five (45) degrees, the sign area is the sum of the areas of the two (2) sign faces.
ii. If the faces of the signs at the closest point are separated by a horizontal distance of two (2) feet or more, even when placed on the same sign support structure, the sign area is the sum of the areas of the two (2) sign faces.
b. Three (3) or more face sign:
i. The sign area is fifty percent (50%) of the sum of the areas of all vertical sign faces.
c. Sign sculpture, statue, or three-dimensional figure:
i. Spherical, free-form, sculptural, or other non-planar sign area is measured as fifty percent (50%) of the sum of the areas using only the four (4) vertical sides of the smallest four (4) vertical sided polyhedron that encompasses the sign structure (six (6) total sides when counting top and bottom), as shown in Figure 11-41-7-D. No more than four-vertical flat polyhedron faces are used to calculate the sign area for a non-planar sign.

B. Sign Height Measurement. Sign height is measured as follows:
1. Freestanding Signs. Sign height is measured as the vertical distance from the average elevation of the finished grade within an eight (8) foot radius from all sides of the sign at the base of a sign to the top of the sign, exclusive of any filling, berms, mounds, or landscaping solely for the purpose of locating the sign, excluding decorative embellishments as defined in Section 11-50-2, and authorized in Section 11-43-3.
a. If natural grade at the base of a sign is higher than the grade of the adjacent road, and the grade has not been artificially raised by fill or other means to a height above the adjacent road, then sign height is measured from the base of the sign at natural grade, as shown in Figure 11-41-7-E.
b. If natural grade at the base of a sign is lower than the grade of an adjacent road, or has been reduced to provide a storm water retention basin, then the height of the sign is measured from the top of curb elevation, as shown in Figure 11-41-7-F.
c. Consideration of natural grade does not include the use of berms or increases in building construction pads, grading of the site, importing of sand, gravel, or other similar means to artificially increase the natural grade level of a site.
2. Building Mounted Signs. The height of wall, fascia, mansard, parapet, or other building mounted signs is the vertical distance measured from the base of the wall on which the sign is located to the top of the sign, as shown in Figure 11-41-7-G.

C. Sign Illumination Measurement. The illuminance of an electronic message panel shall be measured with an illuminance meter set to measure foot-candles accurate to two (2) decimals. Illuminance shall be measured with the unit turned off, and again with the unit turned on displaying a white image for a full color-capable electronic message panel, or a solid message for a single-color electronic message panel. Both measurements shall be taken perpendicular to the face of the electronic message panel at a distance determined by the total square footage of the electronic message panel as provided in Table 11-41-7-C below.
