[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.
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.
A unit of illuminance amounting to one (1) lumen per square
foot.
A light fixture which cuts off all upward transmission of
light.
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.
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.
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.
The amount of light striking a vertical or horizontal plane.
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.
A list of lamps indicating the bulb type, bulb wattage and
manufacturer through which the rated lumens can be determined.
The bulb and lens, diffuser or reflective enclosure.
Light projected onto a property from a fixture not located
on that property.
Measure of brightness of the illumination exiting a bulb,
provided by the manufacture.
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.
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.
The SI unit of illuminance. One (1) lux equals one (1) lumen
per square meter.
A light fixture which does not cut off all upward transmission
of 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.
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.

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.
|
|---|---|
 | |
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.

an acceptable light fixture under a canopy or cantilever.

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]
A.
The
following are exempt from the provisions of this Chapter:
1.
Traffic control signals and devices.
2.
Street lights installed prior to the effective date of the ordinance

maximum extent possible, and lumens shall be minimized to the maximum
extent possible, while still complying with State or Federal Statute.
6.
Seasonal decorations do not have to be shielded; provided that they
do not have a brightness of more than one-tenth (0.1) foot-candles
at the property line on which they are installed.
7.
