YAVAPAI COUNTY PLANNING AND ZONING ORDINANCE Page 147 B. DEFINITIONS: As used in this Ordinance, unless the context clearly indicates otherwise, certain words and phrases shall mean the following: Adaptive Controls: means devices used in conjunction with lighting installations intended to allow the amount of light, area illuminated by light and/or hours during which light is emitted to be controlled. These devices may be remotely addressable or may require on-site adjustment to achieve the desired lighting specifications. Examples of adaptive controls include motion sensors, dimmers and timers. Class 1 Lighting: means all outdoor lighting used for but not limited to outdoor sales or eating areas, assembly or repair areas, advertising and other signs, recreational facilities and other similar applications where color rendition is important to preserve the effectiveness of the activity. Class 2 Lighting: means all outdoor lighting used for but not limited to illumination for walkways, roadways, equipment yards, parking lots and outdoor security where general illumination of the grounds is the primary concern. Class 3 Lighting: means any outdoor lighting used for decorative effects, including but not limited to architectural illumination, flag monument lighting, and illumination of trees, bushes, etc. Development Project: means any residential, commercial, industrial or mixed use subdivision plan or individual building development or remodeling plan, which is submitted to the County for approval. Direct Illumination: means illumination resulting from light emitted directly from a lamp, luminaire or reflector, not light diffused through translucent signs or reflected from other surfaces such as the ground or building faces. Footcandle (fc): is a unit of measure used to specify illuminance; how much light is falling per square foot onto a surface. One (1) footcandle of illumination arises when one (1) lumen is spread onto one (1) square foot of surface. It is the luminous flux per unit area in the Imperial system. One (1) footcandle equals approximately 10 lux. Fully Shielded Fixture: means that fixtures are shielded in such a manner that light rays emitted by the fixture, either directly from the lamp or indirectly from the fixture, are projected below the horizontal from the lowest point of the bulb within the fixture. A practical working way to determine if a fixture or tube is fully shielded: if the lamp or tube, any reflective surface, or lens cover (clear or prismatic) is visible when viewed from above or directly from the side, from any angle around the fixture or tube, the fixture or tube is not fully shielded. Examples of fixtures that are Fully Shielded (Note: to be fully shielded these fixtures must be closed on top and mounted such that the bottom opening is horizontal.):
