1. Area of Face: “False fronts” and mansard roofs will be excluded when calculating the area of the primary face.

2. Height: The overall height of a sign or sign structure is measured from the average grade directly below the sign to the highest point of the sign or sign structure.

3. Legal Setback Line: A setback line established by ordinance beyond which a sign may not be built. A legal setback line may be a property, vision clearance, or vehicle clearance line.

4. Roof Line: The ridge on a gable, peaked roof or the parapet or fascia of a flat roof. A mansard roof is considered a gable roof for the purposes of this definition.

5. Sign Area: The area of the smallest geometric figure which encompasses the facing of a sign, including copy, insignia, background, and borders, but excluding essential sign structure, foundation, or support. For a multi-faced or two-sided sign, the sign area shall be the total of all faces. If the sign consists of more than one (1) section or module, all areas will be totaled.

6. Vision Clearance: Vision clearance is a triangular area formed at a corner lot or parcel by the intersection of dedicated public right-of-way lines and a straight line joining said lines through points fifteen (15) feet back from their intersection. The vision clearance area shall provide an area of unobstructed vision from three and one-half (3 1/2) to eight (8) feet above the top of the curb. Natural topographic features, utility poles, and tree trunks are excluded from this requirement. Refer to Diagram “A” – Visual Clearance (Section 17.04.090).
