(A) The provisions of this subchapter are not intended to prevent the use of any design, material, or method of installation or operation not specifically prescribed by this chapter, provided any such alternate has been approved.
(B) The Building Official may approve any such proposed alternate providing if found that it:
(1) Provides at least approximate equivalence to the applicable specific requirements of this code;
(2) Is satisfactory and complies with the intent of this chapter; or
(3) Has been designed or approved by a registered professional engineer and its content and function promotes the intent of this chapter.
(a) The maximum light level shall be no greater than three foot candles field measured at the property line (ground level) for all non-residential/multi-family properties located adjacent to residentially used or zoned property.
(b) The maximum height of light luminaire when located within 150 feet of residentially used or zoned property shall be 25 feet above the parking surface. All other light luminaires shall have a maximum height of 30 feet above parking surface.
(c) Maximum on-site lighting levels shall not exceed ten foot candles, except for loading and unloading platforms where the maximum lighting levels shall be 20 foot candles.
(d) Canopy luminaires shall include a 90-degree cut-off type, deflector, refractor, or forward throw light fixture. The maximum number of canopy luminaires shall be determined by the following industry standard:
Canopy length (in feet) x canopy width (in feet) x 3 = Maximum No. Lamp Wattage of Canopy Luminaires |
(e) On-site lighting, other than canopy luminaires, shall consist of well shielded luminaires. A 90-degree cut-off type, deflector, refractor, or forward throw light fixture is required when luminaires are greater than 2,000 lumens where located within 150 feet of residentially used or zoned property or street right-of way.
(f) Submittal of photometric plans shall be required with all site plan checks for building permits with a lighted canopy, or on property with lighting parking lots.
(g) Site lighting that may be confused with warning, emergency, or traffic signals is prohibited.
(h) The style of light standards and fixtures shall be consistent with the style and character of architecture proposed on the site. Poles shall be anodized (or otherwise coated) to minimize glare from the light source.
(4) (a) With the exception of lighting for public streets and private streets, all other project lighting used to illuminate buildings, parking lots, walkways, plazas, or the landscape shall be evaluated during the planned development process.
(b) The following table gives minimum and, for under-canopy fueling areas, maximum lighting levels for outdoor facilities used at night:
