This chapter shall be known as, and may be cited as the "East
Hanover Township Outdoor Lighting Ordinance."
To require and set minimum standards for outdoor lighting to:
A. Provide for and control lighting in outdoor public places where public
health, safety and welfare are potential concerns.
B. Protect drivers and pedestrians from the disabling glare of nonvehicular
light sources.
C. Protect neighbors and the night sky from nuisance glare and light
trespass from improperly selected or poorly aimed, placed, applied,
maintained or shielded light sources.
D. Promote energy-efficient lighting design and operation.
E. Protect and retain the intended character of the various portions
of the Township.
As used in this chapter, the following terms shall have the
meanings indicated:
CANDELA
A unit of luminous intensity. A common candle emits light
with a luminous intensity of roughly one candela.
CUTOFF
A lighting fixture from which no more than 2.5% of its lamp's
intensity is emitted at or above a horizontal plane drawn through
the bottom of the luminaire and no more than 10% of its lamp's intensity
is emitted between 80° and that horizontal plane.
FOOTCANDLE
The unit of measure expressing the quantity of light received
on a surface. One footcandle is the illuminance produced by a candle
on a surface one foot square from a distance of one foot.
FULL CUTOFF
A term used by the lighting industry to describe a luminaire
from which no light is emitted at or above a horizontal plane drawn
through the lowest light-emitting portion of the luminaire and no
more than 10% of the lamp's light intensity is emitted at or above
an angle 10° below that horizontal plane, at all lateral angles
around the luminaire. Implicit in the definition is a fixture that
is aimed straight down and has a flat lens. A full-cutoff luminaire,
by definition, also is "fully shielded."
FULLY SHIELDED
Attribute of a luminaire from which no light is emitted at
or above a horizontal plane drawn through the lowest light-emitting
portion of the luminaire.
GLARE
The brightness of a light source that causes annoyance, discomfort,
or loss in visual performance and visibility to the eye.
A.
(1)
Impairs the visibility and creates a potentially hazardous situation
for either pedestrians or motorists or
(2)
Precludes the operation of a nearby business or the provision
of activities, programs or services on nearby property.
B.
(1)
Creates an annoyance or aggravation but does not create a potentially
hazardous situation; or
(2)
Creates an annoyance or aggravation that impairs or impedes
a person's right of quiet enjoyment of his/her property.
ILLUMINANCE
The quantity of incident light measured in footcandles.
LED
Light emitting diode.
LIGHT TRESPASS
Light emitted by a luminaire or lighting installation, which
is cast beyond the boundaries of the property on which the lighting
installation is sited.
LUMEN
The light-output rating of a lamp (light bulb), as used in
the context of this chapter. One lumen equals one footcandle falling
onto one square foot of area.
LUMINAIRE
A lighting fixture complete with the light source or lamp,
the reflector for directing the light, an aperture (with or without
a lens), the outer shell or housing for lamp alignment and protection,
an electrical ballast, if required, and connection to a power source.
LUX
A unit of illuminance stated in lumens per square meter.
One lux is a unit of incident illuminance approximately equal to 1/10
footcandle.
NIT
A unit of measurement of luminance, or the intensity of visible
light, where one nit is equal to one candela per square meter. Nits
are used to describe the brightness of video displays, such as LCD
and CRT monitors.
SHIELDED
A luminaire from which no direct glare is visible at normal
viewing angles by virtue of its being properly aimed, oriented, and
located and properly fitted with such devices as shields, barn doors,
baffles, louvers, skirts or visors.
Any lighting fixture or lighting installation legally installed
and operative on the effective date of this chapter shall be considered
as a lawful nonconformance subject to the following:
A. Nonconforming lighting shall not be changed to any other nonconforming
lighting, structurally altered, altered in any way that increases
its degree of nonconformance, or expanded or extended in scope.
B. Unless minor corrective action, such as re-aiming or shielding, is
deemed by the Township to be an acceptable alternative, a nonconforming
lighting fixture or lighting installation shall be made to conform
with the applicable requirements of this chapter when:
(1) It is deemed by the Township to create a safety hazard.
(2) A fixture is added or replaced with another fixture or fixtures,
abandoned or relocated.
(3) There is a change in use.
In addition to any other remedies provided in this chapter, any violation of §
125-5C hereof, Control of nuisance and disabling glare, shall constitute a nuisance and shall be abated by the Township by either seeking mitigation of nuisance or appropriate equitable or legal relief from a court of competent jurisdiction.
This chapter shall become effective five days after its enactment
by the Board of Supervisors of the East Hanover Township.
