§ 63.406. Special Regulations for Outdoor Lighting Plans.

Outdoor lighting plans must conform to the following regulations where applicable:

(a)

Height of light fixtures. Excepting the public rights-of-way, light fixtures may not exceed 30-feet in height when located within a parking lot, and may not otherwise exceed 15-feet in height. Height shall be measured from finished grade to the top of the fixture. Industrial uses not within 500-feet of a residential use or residential zoning district (measured between property lines) may include fixtures up to 50-feet if necessary to illuminate roads or berths used by trucks.

(b)

Parking lots. To avoid conflict in layout, parking lot lighting must be coordinated with the parking lot's landscaping. Parking lot lighting must conform to the following regulations:

1.

Lamps must be metal halide, compact fluorescent, LED, or a source that produces a CRI of 65 or greater. Wattage may not exceed 400-watts per bulb unless necessary to illuminate roads or berths used by trucks at industrial uses not within 500-feet of a residential use or residential zoning district (measured between property lines).

2.

Illumination levels outside the radius of all light poles must range between 0.6 and 3.6 footcandles. For purposes of this part, the radius of a light pole equals the height of the pole or 20-feet, whichever is greater. Each light pole's radius must be shown on its respective outdoor lighting plan. Areas of a parking lot adjacent to a building canopy, porte-cochere, or other illuminated building overhang may exceed 3.6 footcandles if the luminance otherwise complies with this part.

3.

Light poles must be spaced apart from each other at least 2.5 times the height of the pole.

4.

Decorative acorn-type fixtures may not exceed 18-feet in height and may not exceed 250-watts per bulb. Acorn-type fixtures must have a textured, clear lens and globe, frosted phosphor-coated bulbs, and an internal louvered optical system, or refractor-type glass globes that meet the cutoff standards of this part.

(c)

Walkways, bikeways, and trails. Walkway, bikeway, and trail lighting must conform to the following regulations:

1.

Fixtures must be decorative in appearance, style, and finish.

2.

Lamps must be metal halide, compact fluorescent, LED, or a source that produces a CRI of 65 or greater. Wattage may not exceed 100-watts per bulb.

3.

Illumination levels outside the radius of all light poles must range between 0.2 and 2.5 footcandles. Nature trails, walkways, and bikeways may be exempted from this minimum illumination level by the planning official if he or she finds that the natural environmental objectives and purposes of the trail, walkway, or bikeway would be unreasonably compromised by this minimum lighting requirement and that the location and environmental design of the trail, walkway, or bikeway reasonably provides natural surveillance and otherwise protects public safety.

(d)

Canopied areas for vehicles. Light fixtures in canopied areas for vehicular use such as drive-through facilities at banks and restaurants, at gas stations, porte-cocheres, and in building canopies and awnings within vehicle use areas must be recessed or cutoff fixtures, and must also conform to the following regulations:

1.

Lamps must be metal halide, compact fluorescent, LED, or a source that produces a CRI of 65 or greater. Wattage may not exceed 250-watts per bulb.

2.

Illumination at ground level under canopies may not exceed 20 footcandles.

3.

Canopy fascias may not be internally lit.

4.

Luminaires in canopies may not rely on surrounding structures, including the canopy edge, for required shielding.

(e)

Outdoor automobile dealerships. Illumination at ground level of outdoor display areas for products such as automobiles, recreational vehicles, motorcycles, and boats, may not exceed 40 footcandles for display rows adjacent to external rights-of-way and may not exceed 24 footcandles for all other areas. Illumination at ground level of all other outdoor areas of the dealership may not exceed 10 footcandles.

(f)

Firelanes and driveways. Illumination at ground level of firelanes and driveways may exceed the applicable maximum value provided by this part if the planning official finds that strict compliance with the maximum value would create an unreasonable safety hazard, but in no event may the illumination level exceed 5 footcandles unless the applicable maximum value is greater.

(g)

Awnings. Back and rear lit awnings are prohibited. Awnings may be lit from above, or from the front by fixtures that meet the cutoff requirements of this part. Shielding on awning light fixtures may be tilted above the horizontal in order to effectively illuminate awnings and awning signs from the front, or from an angle, but the fixtures must prevent spill light.

(h)

Parking garages. Interior fixtures must be shielded to prevent light spilling from the garage. Light fixtures on the top deck of a parking garage may not exceed 25-feet in height and must be shielded to prevent light spilling from the boundary of the garage deck.
