COMMON REGULATIONS SECTION 1105.09 EXTERIOR LIGHTING A. Purpose and Applicability. The purpose of this section is to ensure that all exterior site and building lighting shall not affect the reasonable use and enjoyment of adjacent properties but provide minimum levels to enhance safety of individuals and property. Lighting standards shall also protect the safety and operation of vehicles on the public rights-of-way from levels of illumination that are emitted or reflected from light sources of an intensity sufficiently to constitute a safety hazard to vehicular movement. Lighting standards shall apply to all lots except those developed with single family or twofamily dwellings. B. Exterior Lighting Regulations. Exterior site lighting shall be designed, located, constructed and maintained to minimize light and reflected light trespass and spill over off the subject property. Glare shall be minimized from all light sources. i. The average horizontal illumination level on the ground shall not exceed three footcandles (3FC). The light level along a property line adjacent to a residentially-zoned or used property shall not exceed an average intensity of one-half footcandle (0.5FC). ii. The height of parking lot lighting shall not exceed twenty feet (20’) above grade and shall direct light downward, i.e. cut-off type fixtures. In conjunction with a major site plan review, the Planning Commission may require a lower standard based upon specific characteristics of the site. iii. The color of parking lot lighting poles and other lighting infrastructure shall match or complement the colors of the building’s architecture, as approved by the Planning Commission. iv. For pedestrian areas, decorative low light fixtures shall be used and the height of the fixture shall not exceed fourteen feet (14’) above grade. v. Exterior building illumination shall be from concealed sources. Strobe or flashing lights and exposed neon lights are not permitted. Lighting fixtures shall not generate excessive light levels, cause glare, or direct light beyond the facades onto neighboring property, streets, or the night sky. The maximum illumination of any vertical surface or angular roof surface shall not exceed four footcandles (4FC). vi. Security lighting shall be full, cut-off type fixtures, shielded and aimed so that illumination is directed to the designated areas with the lowest possible illumination level to effectively allow surveillance. vii. Lighting fixtures used to illuminate the area below a freestanding canopy shall be recessed so that the lens cover is recessed or flush with the bottom surface (ceiling) of the canopy. However, indirect lighting may be used where a shielded source of light is beamed upward and then reflected down from the underside of the canopy. 156
