As used in this chapter, the following terms shall have the
meanings indicated:
FOOTCANDLE
A unit of measurement of illuminance (one footcandle equals
one lumen per square foot of area).
GLARE
Illuminance within the visual field of a human eye which
is sufficiently greater than the intensity of illuminance to which
the eye is adapted that it causes annoyance, discomfort, nuisance,
and/or loss in visual performance and visibility.
ILLUMINANCE
The total amount (density) of visible light incident upon
(i.e., illuminating) a point of a surface from all directions above
the surface measured in footcandles (note: the "surface" may be a
part, or all, of a physical object or an imaginary plane).
LIGHT FIXTURE
An electrically powered lighting device consisting of a lamp,
a lamp holder, an electrical ballast (if necessary), and the means
for connecting the device to an electrical power source.
LIGHT TRESPASS
Any form of illumination emanating from a light fixture or
light source whether internally or externally illuminated on a property
that penetrates another property and creates a nuisance, annoyance,
or glare.
LIGHTING
The deliberate utilization of one or more artificial light
sources to achieve an aesthetic or intended effect.
LUMEN
Measurement of light output. One lumen is equal to the amount
of light emitted by one candle that falls on one square foot of surface
located one foot away from the candle.
OBJECTIONABLE DIRECT GLARE SOURCE
A glare resulting from artificial light sources and excessive
levels of illumination or insufficiently shielded light sources emanating
from light fixtures in the field of view where the lens, lamp, or
reflector is offensively visible above a height of five feet at a
property line, public or private roadway. Rule of thumb: if the lamp
(bulb) is objectionably visible from outside the illuminated property's
boundary, then it's a direct glare source. Rule of thumb: If you must
squint to see due to glare within your field of view, then it's objectionable.
OUTDOOR LIGHTING
The lighting of areas exterior to the walls of enclosed buildings
and/or within structures having open or partially open walls such
as canopies, porte cocheres, pavilions, gazebos, etc., artificial
light sources and/or light fixtures.
All commercial properties shall comply with the lighting requirements set forth in §
164-9A(6).
All property owners and occupants shall control the placement
and direction of all exterior lighting located within the property
lot lines and ensure the lighting shall not create a nuisance, annoyance,
or light trespass to adjacent properties or public rights-of-way.
Failure to comply with the requirements set forth above shall be a
violation of this chapter. The provisions of this chapter shall be
enforced by the Enforcement Officer.
Whenever an outdoor light fixture and/or artificial light source
is determined to be in violation of this chapter, a notice of violation
shall be given to the owner of the property to turn off the light
immediately, and, thereafter, remove same within 30 days.
A violation of this chapter shall be further punishable as provided in Chapter
1, General Provisions, Article
III, General Penalty.
