(a) All outdoor lighting fixtures regulated according to this Chapter, including but not limited to those used for parking areas, buildings, building overhangs, canopies, signs, displays and landscaping, shall be full-cutoff type fixtures, unless exempt per Section 1282.09, Exemptions.
(1) Full-cutoff fixtures shall be installed and maintained so that the shielding is effective as described in Section 1282.03(b) above.
(2) Automobile-oriented uses such as gasoline stations, service stations and drive-through facilities shall install recessed ceiling fixtures in any canopy.
(3) Signs that are wholly illuminated from within and freestanding signs that are externally illuminated with an exposed incandescent lamp not exceeding twenty-five (25) watts shall not require shielding.
(b) All on-site lighting of buildings, lawns, parking areas and signs shall be designed so as not to shine onto any adjacent residential property or building, or to cause glare onto any public street or vehicle thereon.
(c) Measurement.
(1) Light levels shall be measured in foot-candles with a direct reading, portable light meter. Readings shall be taken only after the cell has been exposed long enough to take a constant reading.
(2) Measurements shall be taken at the property line, along a horizontal plane at a height of three-and-one-half (3.5) feet above the ground.
(d) For all conditional and non-residential uses in Residential Districts, all non-essential outdoor lighting fixtures, including parking, sign, display and aesthetic lighting, shall be turned off after business hours. Only that lighting needed for safety or security may remain lit after close of business, in which case the lighting shall be reduced to the minimum level necessary.
(e) Maximum Permitted Illumination at the Property Line. Unless otherwise noted in this Code, the maximum foot-candle strength at a residentially zoned property line shall be one half (0.5) foot-candle. At non-residentially zoned property lines the level shall not exceed one foot-candle.
(f) Maximum Height of Light Poles. The total height of exterior lighting poles shall not exceed the following height regulations. Height shall be measured from the average grade surrounding each light pole:
Districts: | Maximum Height |
R-1 through R-4 | 16 feet |
B-1 through B-3 | 22 feet |
M-1 and M-2 | 28 feet |
