(a) Lighting shall be designed in a consistent and coordinated manner for the entire site. It shall be used to accent key architectural elements and/or to emphasize landscape features, and shall be designed to avoid the creation of hot spots, glare or a nuisance.
(b) Light fixtures shall be designed as an integral design element that complements the design of the project through style, material or color.
(c) Lighting of on-site buildings shall be limited to wall-washer type fixtures or up lights, which do not produce spillover lighting.
(d) Site lighting shall not incorporate floodlight fixtures mounted on building walls, roofs or poles.
(e) Lighting at building entrances may exceed allowable standards of intensity for safety purposes upon demonstration to Obetz that compliance with this lighting criteria will create a public safety hazard and that special and unique conditions exist requiring additional lighting at building entrances; provided, however, that such lights shall be directed downward to minimize spillover lighting and glare.
(f) Lighting intensities shall be designed as recommended by IES.
(g) Lighting levels for fire lanes or driveways at building entrances shall not exceed five (5) foot-candles.
(h) Lighting standards, including the pole height and fixture, shall be a maximum of 30 feet in height within the parking lot and shall be a maximum of 15 feet in height within non- vehicular pedestrian areas.
(i) At service stations and convenience centers, lighting under canopies, porte cocheres, etc. should be recessed and shall use flat glass lenses. If not recessed, the box type or other fixture shall be opaque on all sides (no light shall show from any side of the fixture) and shall use flat glass lenses.
(j) The light source shall be metal halide (maximum 250 watts) or fluorescent.
(k) The maximum foot-candle level shall be thirty (30) fc (average maintained maximum).
(l) Clear flat lenses may be used with phosphor coated metal halide lighting or a clear metal halide light may be used with a diffused flat lens.
(m) Exterior illumination shall be installed with houseside shields and reflectors (as required), and maintained in such a manner, as to confine direct light rays to the premises and minimize light rays and glare onto adjacent properties.
(n) Parking areas (except for parking areas at service stations and convenience centers located under an awning, canopy, porte-cachere, etc) shall be illuminated as follows:
(1) Parking area lighting shall be decorative in nature and shall be shielded from adjacent properties by utilizing flat glass lenses, house-side shields and "NEMA" type II, III and IV reflectors (otherwise known as decorative cut-off luminaries).
(2) The lamp source shall be metal halide. The maximum wattage shall not exceed 400 watts. Lighting illumination levels range from a minimum of 0.6 fc, to a maximum (outside a twenty foot (20') radius from the pole) of 3.6 fc. A photometric plan is required. In the alternative, each fixture/lamp source shall be spaced no closer than three pole heights to any other light source, other than wall mounted lights.
(3) Phosphor coated lamps shall be utilized where the lamp source is not hidden by the luminaire housing or equipped with a diffused lens.
(4) Decorative acorn type fixtures shall not exceed eighteen (18) feet in height and two hundred and fifty (250) watts per bulb and shall have a textured clear lens/globe, frosted/phosphor coated bulbs and an internal optical system.
(5) The use of horizontal lamps is highly recommended.
(o) Pedestrian walkways and bikeways shall be illuminated as follows:
(1) The lamp source shall be decorative in appearance, style and finish. Selected luminaries shall have the lamp source shielded from view.
(2) The lamp source shall be metal halide within a development but, may be high-pressure sodium adjacent to public right-of-way. The maximum wattage shall not exceed 100 watts. Lighting illumination levels range from a minimum of 0.2 fc to a maximum of 2.5 fc. A photometric plan is required. In the alternative, each fixture/lamp source shall be spaced no closer than six times the overall height of the fixture, including both poles and luminaries. This is for other than against wall mounted lights. Phosphor coated lamps shall be utilized where the lamp source is not hidden by the luminaire housing or equipped with a diffused lens.
