The requirements of this article of this chapter apply to all
outdoor lighting installations, as follows:
A. Outdoor lighting installations which are employed for nighttime area
illumination of parking lots, car sales lots, yards, roadways, streets,
driveways, walkways, bikeways, cartways, entryways and similar areas
or lots.
B. Outdoor lighting installations which are located on any property
in any zoning district within Union Township except for the following:
(1) A lot which is comprised of one single- or two-family dwelling.
(2) A lot which is being used as a farm.
All luminaires employed in outdoor area and roadway lighting
installations shall be the cutoff luminaire type.
A. The candlepower distribution classification of the luminaire as a
cutoff type shall be in accordance with the ANSI/IES lighting definitions
and the IES Lighting Handbook. The manufacturer of the luminaire shall
provide certification of the cutoff classification based on photometric
testing performed in accordance with the IES Lighting Handbook and
the applicable testing procedures referenced therein. The requirement
for the use of cutoff luminaire types shall include, but is not limited
to, the following outdoor area and roadway lighting configurations:
(2) Luminaires mounted on the exterior of buildings and structures.
(3) Luminaires mounted on or within exterior canopies of buildings and
structures.
(4) Pedestal- or bollard-mounted luminaires.
B. Cutoff luminaires shall be mounted plumb and level in accordance
with the intended application of their design. For the purposes of
this requirement, the photometric nadir of the luminaire (0° vertical
angle of the candlepower distribution) shall be oriented plumb and
the vertical angle of 90° above nadir (horizontal) shall be oriented
level. Cutoff luminaires shall not be installed in a canted or tilted
position which permits candlepower distribution above the horizontal.
C. Exception. Luminaires which do not meet the strict definition for
cutoff luminaires, yet employ advanced or alternative technology which
causes the photometric performance to approach that of cutoff luminaires,
may be approved by Union Township or its duly appointed representative
on a case-by-case basis. Such luminaires include, but are not limited
to, period-style luminaires with refractive globes and internal cutoff
reflectors.
D. Exception. Luminaires with a total initial lumen output of 10,000
lumens or less shall be permitted for decorative, accent or supplementary
lighting applications, provided that glare shields are incorporated
which cut off the candlepower distribution at and above the horizontal
(level).
The maximum maintained illuminance levels permitted at the property
line(s) during the nighttime, produced by the sum of all outdoor area
lighting installations on said property, shall be as measured at grade
in horizontal foodcandles or horizontal lux according to Table 155-15
below.
A. Exception. By written agreement between the respective property owners,
an outdoor lighting installation on one property may illuminate areas
or roadways on adjacent property beyond the property line.
B. Exception. This requirement does not apply to outdoor roadway lighting
installations intended for the nighttime illumination of public roadways,
streets, highways, alleys, cartways and the like.
C. Exception. At designated vehicular, cyclist and pedestrian entries/exits
between the properties and public roadways, streets, highways, alleys,
valleys, cartways and the like, provided that the excepted area of
illumination (maintained illuminance levels at grade higher than permitted
in Table 155-15) is limited to the said property and the adjoining
pavement and right-of-way of public roadways, streets, highways, alleys,
cartways and the like. The excepted area of illumination shall not
extend beyond 50 feet from the center line of the designated entry/exit
in any direction along the property line(s) of the said property.
