[Ord. No. 2470 §1, 3-27-2012]
Purpose. The exterior lighting design regulations specified in this Section are intended to foster aesthetically pleasing development which will protect and preserve the appearance, character, general health, safety and welfare of the City and will preserve the value of properties located within the Olive Boulevard Corridor. Specifically, these regulations are intended to control glare and light trespass, minimize obstructive light, conserve energy and resources while maintaining safety, security and productivity and curtail the degradation of the nighttime visual environment.
[Ord. No. 2470 §1, 3-27-2012]
The following definitions shall be applicable to this Article.
FIXTURE
The assembly that holds the lamp (bulb) in a lighting system, including elements designed to give light output control, such as a reflector (mirror) or refractor (lens), the ballast, housing and attachment parts.
FOOT-CANDLE
A unit of illuminance amounting to one (1) lumen per square foot.
FULL-CUTOFF
A light fixture which cuts off all upward transmission of light.
FULLY SHIELDED
A fully shielded luminaire is a luminaire constructed or shielded in such a manner that all light emitted by the luminaire, either directly from the lamp or indirectly from the luminaire, is projected below the horizontal plane through the luminaire's lowest light emitting part as determined by photometric test or certified by the manufacturer.
GLARE
The sensation produced by luminance within the visual field that is sufficiently greater than the luminance to which the eyes are adapted or which causes annoyance, discomfort or loss in visual performance and visibility.
HIGH INTENSITY DISCHARGE (HID) LIGHTING
A family of bulb type including mercury vapor, metal halide, high pressure and low pressure sodium which glow when an electric current is passed through a gas mixture inside the bulb.
HORIZONTAL (OR VERTICAL) FOOT-CANDLES
The amount of light striking a vertical or horizontal plane.
ILLUMINANCE
The quantity of light or luminous flux arriving at a surface divided by the area of the illuminated surface, measured in lux or foot-candles.
INVENTORY OF LIGHTS
A list of lamps indicating the bulb type, bulb wattage and manufacturer through which the rated lumens can be determined.
LIGHT SOURCE
The bulb and lens, diffuser or reflective enclosure.
LIGHT TRESPASS
Light projected onto a property from a fixture not located on that property.
LUMEN
Measure of brightness of the illumination exiting a bulb, provided by the manufacture.
LUMINAIRE
A complete lighting unit consisting of a lamp or lamps, together with the parts designed to distribute the light, to position and protect the lamps and to connect the lamp to the power supply.
LUMINANCE
The physical quantity corresponding to the brightness of a surface (e.g., a lamp, luminaire, sky or reflecting material) in a specified direction. The luminous intensity of an area of the surface divided by that area measured in candelas per square meter.
LUX (LX)
The SI unit of illuminance. One (1) lux equals one (1) lumen per square meter.
NON-CUTOFF
A light fixture which does not cut off all upward transmission of light.
OBTRUSIVE LIGHT
Spill light which, because of quantitative, directional or spectral context, gives rise to annoyance, discomfort, distraction or reduction in the ability to see essential information.
SPILL LIGHT
Light emitted by a lighting installation that falls outside the boundaries of the property on which the installation is sited.
[Ord. No. 2470 §1, 3-27-2012]
A. 
All luminaries of eighteen hundred (1,800) or more lumens shall be full-cutoff as installed. For luminaires under eighteen hundred (1,800) lumens, the bulb shall be frosted glass or shall be installed behind a translucent cover.
Figure 1-A. The following figure provides an illustration of a full-cutoff light fixture.
Figure 1-B. The following figure provides an illustration of a full-cutoff light fixture.
Figure 1-C. The following figure provides an illustration of a full-cutoff light fixture.

B. 
The maximum illumination level at five (5) feet inside an adjacent residential parcel or right-of-way, or beyond, from light emitted from an artificial light source shall be one-tenth (0.1) horizontal foot-candles and one-tenth (0.1) vertical foot-candles. Maximum illumination at ten (10) feet inside an adjacent commercial or industrial parcel or on a roadway or beyond shall not exceed one-tenth (0.1) horizontal foot-candles or one-tenth (0.1) vertical foot-candles.
C. 
No line of sight to a bulb is permitted five (5) feet or more beyond a residential or public right-of-way property line by an observer viewing from a position that is level with or higher than the ground below the fixture. Compliance shall be achieved with fixture shielding, directional control designed into the fixture, fixture location, fixture height, fixture arm or a combination of these factors.
D. 
The total height of all light poles, including the base, pole and fixture, shall be limited to sixteen (16) feet.
E. 
All light pole fixtures shall be full-cutoff fixtures, parallel with the ground at a zero (0) tilt and shall not have any light source projecting beyond the plane of its cover.
Figure 2-A. The following figure provides an illustration of a full-cutoff light fixture parallel with the ground.
Figure 2-B. The following figure provides an illustration of a light fixture that is not a full-cutoff fixture and emits light beyond the plane cover.
 428.620E.tif
F. 
All wall pack fixtures located on an exterior wall plane must be full-cutoff and may not have the bulb projecting beyond the plane of its cover.
G. 
Wall fixtures located under a canopy or cantilever must be positioned so that the fixture is flush with the soffit under the eave. Any projection of the light fixture or bump out is prohibited.

H. 
Floodlights or spotlights attached to light pole or any light fixture extending above a building wall are prohibited, unless requested by civil authorities for public safety. No floodlight may be aimed higher than forty-five degrees (45°) above a horizontal plane parallel with the ground.
I. 
The nighttime use of white lighting or white strobe lighting on any communication tower is prohibited. (Nighttime white strobe lighting is not required by the FAA.) Applicants must show proof of any such FAA requirements.
J. 
The Planning and Community Design Commission may, by request, approve the use of architectural up lighting or down lighting to highlight an exterior building surface.
[Ord. No. 2470 §1, 3-27-2012]

The following are exempt from the provisions of this Chapter:
1. 
Traffic control signals and devices.
