3 Exhibit A Strikethrough text is proposed to be deleted and underlined text is proposed to be added. Sec Purpose. ARTICLE XX Exterior Lighting The Town is experienced ing a significant expansion in population and construction, resulting in increased use of exterior illumination on an urban scale. This Article is intended to help maintain the health, safety and welfare of the residents of the Town through regulation of exterior lighting as reflected by the following goals: (1) Promote safety and security; (2) Help preserve the small town character; (3) Eliminate the escalation of nighttime light pollution; (4) Reduce glaring and offensive light sources; (5) Provide clear guidance to builders and developers; (6) Encourage the use of improved technologies for lighting; and (7) Conserve energy. (Ord. 29 2, 1998) Sec Definitions. As used in this Article, the following terms shall have the meanings indicated: Color Rendering Index (CRI) is a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source. Correlated Color Temperature (CCT) The color temperature of a light source is determined by comparing its chromaticity with that of an ideal black-body radiator. The temperature (usually measured in kelvin (K)) at which the heated black-body radiator matches the color of the light source is that source's color temperature. Yellow-red colors are considered warm, and bluegreen colors are considered cool. Fixture height means the vertical distance from the ground directly below the centerline of the fixture to the lowest direct light emitting part of the fixture. Fluorescent lamp or fluorescent tube: is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. 1

4 Foot-candles means the illuminance on a one square-foot surface of which there is a uniformly distributed flux of one lumena unit of illumination of a surface that is equal to one (1) lumen per square foot. For the purposes of these regulations, foot-candles shall be measured at a height of three (3) feet above finished grade. Fully shielded light means light fixtures shielded or constructed so that no light rays are directly emitted by the installed fixture at angles above the horizontal plane as certified by a photometric test report. The fixture must also be properly installed to effectively down direct light in order to conform with the definition. Exemptions from this definition may be allowed for aesthetic lighting elements such as shades with perforated patterns and opaque diffusers. Glare: Excessive contrast or intense and/or blinding light which creates visual discomfort or disability. High intensity discharge light source (HID) means light sources characterized by an arc tube or discharge capsule that produces light, with typical sources being metal halide, high pressure sodium and other similar types which are developed in accordance with accepted industry standards. An Incandescent and/or halogen light source is the emission of light (visible electromagnetic radiation) from a hot body due to its temperature. Incandescence occurs in incandescent light bulbs, because the filament resists the flow of electrons. This resistance heats the filament to a temperature where part of the radiation falls in the visible spectrum. Landscape Lighting: Luminaires mounted in or at grade but not more than three (3) feet above grade and used solely for landscape rather than area lighting. A light-emitting diode (LED) is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device, as in the simple LED circuit. The effect is a form of electroluminescence where incoherent and narrow-spectrum light is emitted. Light fixture is an electrical device used to create artificial light or illumination. A luminaire is a lighting fixture complete with the light source or lamp, the reflector for directing the light, an aperture (with or without a lens), the outer shell or housing for lamp alignment and protection, an electrical ballast, if required, and connection to a power source. Light trespass means the shining of light produced by a light fixture beyond the boundaries of the property on which it is located. means light escaping the boundaries of the property in excess of.2 footcandles. Lumen is the unit of measure used to quantify the amount of light produced by a lamp or emitted from a luminaire. Technically, if a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, its total luminous flux emitted into that angle is one lumen. Alternatively, an isotropic one-candela light source emits a total luminous flux of exactly 4π lumens. Luminaire: A complete lighting unit consisting of one or more electric lamps, the lampholder(s), any reflector or lens, ballast or transformer, and any other components and accessories. 2

5 Point light source means the exact place from which illumination is produced (i.e., a light bulb filament or discharge capsule). (Ord. 29 2, 1998) Sec Lighting plans. (a) An outdoor lighting plan shall be submitted in conjunction with any subdivision, planned unit development, site plan development review, site plan development exemption, special review application and building permit application for a commercial or multifamily building. Said plan shall show the following: (1) The location and height above grade of light fixtures; (2) The type (such as incandescent, halogen, high pressure sodium) and total lumens luminous intensity of each light source; (3) The type of fixture (such as floodlight, full-cutoff, lantern, coach light); (4) Calculated estimates for site illumination resulting from the lighting, measured in footcandles; and (5) Other information deemed necessary to document compliance with the provisions of this Article. (b) Applications for single-family and duplex building permits shall be required to provide all information necessary to document compliance with the provisions of this Chapter, as determined by the Building Official. Said information may be required in the form of a lighting plan consistent with Section (a)(1). (Ord. 29 2, 1998) Sec Street lighting and lighting for common areas. All lighting illuminating public right-of-ways, and easements or private streets, and public or private walkways shall conform with the following standards: (1) All light fixtures must be fully shielded and use a full cut-off fixture to minimize light spill towards the private property. (2) Maximum fixture height shall be sixteen (16) feet. Exemptions up to a maximum of twenty-five (25) feet may be granted for street lights located at opposing corners of intersections. (3) A minimum of one hundred (100) feet shall be maintained between street light fixtures. Exemptions to this standard may be considered when fixtures are located on opposing corners of an intersection, at a pedestrian crosswalk or where similar special or unique conditions exist. Exemptions may be considered only where fixture type, placement and light intensity are modified to conform with the intent of the minimum spacing requirement. (4) Fixture types shall be selected from a list of Town-approved designs. Said list will be approved by the Town Council. Property owners and developers may petition the Council for inclusion of new designs. (Ord. 29 2, 1998; Ord. 33 B1, 2003) (5) Walkways/Bikeways and Pedestrian areas to be used in common areas and public areas that are not lit by streetlights: These areas shall be illuminated with low level bollards 3

6 unless waived by the Town Planner. Average light level for these areas shall be measured at finished grade shall average at most 0.5 foot-candles. Lighting shall be directed downward, be pedestrian-friendly, and fully shielded. Light sources shall be no more than 800 lumens, regardless of type. Sec Nonresidential lighting standards. The following lighting standards shall be applicable to all nonresidential properties including mixed uses: (1) Outdoor lighting used to illuminate parking spaces, driveways, maneuvering areas or buildings shall be designed, arranged and screened so that the point light source shall not be visible from adjoining lots or streets. The light level shall not exceed fifteen (15) an average of one (1) foot-candles as measured three (3) feet above at finished grade. Lighting for pedestrian entrances, stairways, and loading docks shall not exceed five (5) foot-candles.
