This chapter shall be known as the "Outdoor
Lighting Law."
The Town Board of the Town of Ithaca finds the
following:
A. Good outdoor lighting at night benefits everyone.
It increases safety, enhances the Town's nighttime character, and
helps provide security.
B. New lighting technologies have produced lights that
are extremely powerful, and these types of lights may be improperly
installed so that they create problems of excessive glare, light trespass,
higher energy use, and can negatively impact animals. Excessive glare
can be annoying and can cause safety problems. Light trespass reduces
everyone's privacy, and sky glow can interfere with observatories.
If these problems are addressed, the resulting reduced energy use
can benefit everyone through reduced pollution and lower energy costs.
C. There is a need for a lighting law that recognizes
the benefits of outdoor lighting and provides clear guidelines for
its installation and operation so as to help maintain and complement
the Town's character.
D. Appropriately regulated, and properly installed, outdoor
lighting will contribute to the safety and welfare of the residents
and visitors of the Town.
The purpose of this chapter is to promote the
public safety and welfare by regulating outdoor lighting to reduce
the problems created by improperly designed and installed outdoor
lighting. This chapter is intended to eliminate problems of glare
and minimize light trespass to keep unnecessary direct light from
shining onto abutting properties or streets, to help reduce the energy
costs of outdoor lighting, and to reduce sky glow.
As used in this chapter, the following terms
shall be defined as follows:
DIRECT LIGHT
Light emitted directly from the lamp, off the reflector or
reflector diffuser, or through the refractor or diffuser lens, of
a luminaire.
DISABILITY GLARE
Glare resulting in reduced visual performance and visibility.
It is often accompanied by discomfort.
ENFORCEMENT OFFICIAL
The official charged with the duty to enforce the zoning
and other laws, ordinances, codes, and regulations relating to buildings
and property.
FIXTURE
The assembly that houses the lamp or lamps and can include
all or some of the following parts: a housing, a mounting bracket
or pole socket, a lamp holder, a ballast, a reflector or mirror, and/or
a refractor or lens.
FLOOD- OR SPOTLIGHT
Any light fixture or lamp that incorporates a reflector,
a refractor, or a prismatic lens to concentrate the light output into
a directed beam in a particular direction.
FULLY SHIELDED LUMINAIRE
A luminaire constructed and installed in such a manner that
all light emitted by it, either directly from the lamp or a diffusing
element, is projected below a horizontal plane through the luminaire's
lowest light-emitting part.
GLARE
Light emitted from a luminaire with an intensity great enough
to reduce a viewer's ability to see, and in extreme cases causing
momentary blindness.
INDIRECT LIGHT
Direct light that has been reflected or has scattered off
other surfaces.
LAMP
The component of a luminaire that produces the actual light
(commonly called a "bulb").
LIGHT TRESPASS
The shining of light produced by a luminaire beyond the boundaries
of the property on which it is located.
LUMEN
The unit used to measure the actual amount of light which
is produced by a lamp. One footcandle is one lumen per square foot.
For the purposes of this chapter, the lumen-output values shall be
the initial lumen output ratings of a lamp. The lumen output of most
lamps is listed on the packaging.
LUMINAIRE
A complete lighting system, including a lamp or lamps and
a fixture.
OUTDOOR LIGHTING
The nighttime illumination of an outside area or object by
any man-made device located outdoors that produces light by any means.
SKY GLOW
The overhead glow from light emitted sideways and upwards,
including light reflected upward from the ground or other surfaces.
Sky glow is caused by the reflection and scattering of various forms
of light by dust, water, and other particles suspended in the atmosphere.
TEMPORARY OUTDOOR LIGHTING
The specific illumination of an outside area or object by
any man-made device located outdoors that produces light by any means
for a period of less than seven days, with at least 180 days passing
before being used again.
All new and replacement public and private outdoor lighting installed in the Town of Ithaca after the effective date of this chapter shall be in conformance with the requirements of this chapter. Certain lighting in place on the effective date of this chapter shall also be subject to the requirements of this chapter, as specified in §
173-14. Any inconsistent language in the Town of Ithaca Code is superseded by the requirements of this chapter.
Any light source permitted by this chapter may
be used for lighting of outdoor recreational facilities (public or
private), such as, but not limited to, football fields, soccer fields,
baseball fields, softball fields, tennis courts, or show areas, provided
all of the following conditions are met:
A. All fixtures used for event lighting shall be fully shielded as defined in §
173-4 of this chapter.
B. All events shall be scheduled so as to complete all
activity before or as near to 10:30 p.m. as practical, but under no
circumstances shall any illumination of the playing field, court,
or track be permitted after 11:00 p.m. except to conclude a scheduled
event that was in progress before 11:00 p.m.

C. Existing nonconforming luminaires that direct light
toward streets or parking lots and cause disability glare to motorists,
pedestrians, or cyclists shall be either shielded or redirected within
