(a) 
The purpose of this chapter is to improve the safety, travel conditions and general welfare of residents by the following methods of lighting design:
(1) 
Control of direct glare from lighting fixtures.
(2) 
Reduction of spill light onto adjacent properties.
(3) 
Reduction of light pollution.
(4) 
Selection of lighting fixtures that accomplish the above.
(5) 
Promote lighting designs that provide the required security but do not cause a nuisance to neighbors or the traveling public.

As used in this chapter, the following terms shall have the meanings indicated:
FIXTURE HEIGHT
The distance from the top of the light fixture to the ground level at the concrete base of the light pole.
FOOTCANDLE
Standard unit of measure for illuminance on a given area. Specifically, this represents a value of one lumen per square foot of illuminance. All footcandles referenced in this chapter are initial footcandles and not maintained footcandles.
FULLY SHIELDED
Outdoor luminaires shielded or constructed so that all of the light rays emitted by the fixture are projected below a horizontal plane passing through the lowest point of the fixture. Refer to IESNA guidelines. These guidelines specifically state that the candlepower per 1,000 lumens does not numerically exceed 2.5% at an angle of 90° above (nadir) horizontal and 10% at a vertical angle of 80° above nadir. Dropped or sagged lens fixtures shall not be permitted.
GLARE or DIRECT GLARE
Light directly visible to a viewer's eye, either directly from a light source or reflected or refracted from the light source.
HORIZONTAL FOOTCANDLE (HFE)
The illuminance measured on a horizontal surface.
IESNA
Illumination Engineering Society of North America.
INITIAL FOOTCANDLE
Illuminance of light when new light fixtures and new lamps are energized. No dirt buildup is present and no use of maintenance factors applied to lighting calculations.
LIGHT TRESPASS (SPILL LIGHT)
Unwanted light received in areas beyond the property line of the illuminated area.
LUMINAIRE
The complete assembly of a light fixture that includes the lamp, lamp housing, poles, mounting brackets and all other accessories. The term "fixture" or "lighting fixture" when used shall also mean "luminaire."
MAINTAINED FOOTCANDLE
Illuminance of light adjusted for maintenance factor accounting for dirt buildup.
OUTDOOR LIGHT FIXTURES
Artificial illuminating devices that are used for illumination or advertisement, These devices may be utilized on a temporary or permanent basis. Areas used include, but are not limited to, the descriptions below:
(1) 
Parking lots or garages.
(2) 
Recreational areas such as fields, parks, stadiums or playgrounds.
(3) 
Building facades, canopies or overhangs.
(4) 
Roadway lighting.
RESIDENTIAL PROPERTY OR PROPERTY LINE
The property line of an individual property where individual lots exist or the perimeter property line of the overall residential development where there are no individual lots.
VERTICAL FOOTCANDLE
The amount of illuminance measured on a vertical surface.
[Added 10-15-2024 by Ord. No. 1705]
(a) 
All luminaires shall be fully shielded as defined in Subsection B.
(b) 
All outdoor fixtures shall be installed and placed in such a fashion so that light trespass values meet or exceed the requirements for spill light as defined in this chapter.
(c) 
Lighting sources for all exterior fixtures shall be LED (light-emitting diode); metal halide; high-pressure sodium; fluorescent or incandescent. Such lighting sources have a color temperature range between 2,700 and 4,000 Kelvin.
(d) 
The installation of building-mounted light fixtures shall be governed by the following:
(1) 
The maximum height of any luminaires within 80 feet of a residential zoning district shall be 14 feet. Fixtures within 80 feet of a residential zoning district shall be equipped with factory-prepared external shielding on all sides visible from that residential district.
(2) 
A maximum luminaire height of 20 feet for all other areas.
(3) 
All light fixtures mounted in canopies or overhangs shall be recessed and shall not have drop dish lenses. Any lenses shall be located at or above the horizontal plane at the bottom of the luminaire.
(e) 
The installation of light fixtures installed within a building or structure having the• capability of producing direct glare beyond the building's property line shall be governed by the following. This type of installation is representative for such buildings as multilevel parking garages and elevated ramps.
(1) 
All fixtures along the perimeter of the structure that cause direct glare shall be factory equipped with external shields.
(2) 
Any rooftop pole fixture on elevated parking structures shall be equipped with external shields.
(f) 
The installation of individually mounted light fixtures shall be governed by the following:
(1) 
The maximum height of any luminaires within 80 feet of a residential zoning district shall be 14 feet.
(2) 
The maximum height of any luminaires for all other locations shall not exceed 25 feet. Lamps for these luminaires shall not exceed 400 watts.
(g) 
Searchlights, beacon lights or similar fixtures that project a beam of light into the air are prohibited.
(h) 
Neon lights. Flashing, signaling or traveling neon lights are not permitted under any circumstance. "Traveling" neon lights shall be defined as neon lights that give the appearance of motion of the light wave within the sign.
[Added 10-15-2024 by Ord. No. 1705]
(a) 
All light fixtures shall be fully shielded and shall be installed in such a manner that the light source and direct glare is not visible to any adjacent properties.
(b) 
Light levels shall not exceed 1.0 initial horizontal footcandle at any property line adjacent to other nonresidential, institutional, commercial properties or public rights-of-way.
(c) 
Properties adjacent to residential districts. The value of spill light shall not exceed 0.1 initial footcandle at the property line of the residential property or the development where the residential property exists.
