For the purposes of this chapter, terms used shall be defined
as follows:
DIRECT LIGHT
Light emitted directly from the lamp, off of the reflector
or reflector diffuser, or through the refractor or diffuser lens of
a luminaire.
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.
FLOODLIGHT or SPOTLIGHT
Any light fixture or lamp that incorporates a reflector or
a refractor to concentrate the light output into a directed beam in
a particular direction.
GLARE
Light emitting from a luminaire with an intensity great enough
to reduce a viewer's ability to see and in extreme cases to cause
momentary blindness.
HEIGHT OF LUMINAIRE
The height of a luminaire shall be the vertical distance
from the ground directly below the center line of the luminaire to
the lowest direct-light-emitting part of the luminaire.
INDIRECT LIGHT
Direct light that has been reflected or has scattered off
of other surfaces.
LAMP
The component of a luminaire that produces the actual light.
LIGHT TRESPASS
The shining of light produced by a luminaire beyond the boundaries
of the property on which it is located.
LUMEN
A unit of luminous flux. 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.
LUMINAIRE
A complete lighting system and includes a lamp or lamps and
a fixture.
OUTDOOR LIGHTING
The illumination of an outside area or object by any man-made
device located outdoors that produces light by any means.
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 public and private outdoor lighting installed in the Town
of Kennebunkport shall be in conformance with the requirements established
by this chapter.
A. Control of glare; luminaire design factors.
(1) Any luminaire with a lamp or lamps rated at a total of more than
1,800 lumens and all flood or spot luminaires with a lamp or lamps
rated at more than 900 lumens shall not emit any direct light above
a horizontal plane through the lowest direct-light-emitting part of the luminaire.
(2) Any luminaire with a lamp or lamps rated at a total of more than
1,800 lumens and all flood or spot luminaires with a lamp or lamps
rated at a total of more than 900 lumens shall be mounted at a height
equal to or less than the value 3 + (D/3), where D is the distance
in feet to the nearest property boundary.
(3) The maximum height of the luminaire may not exceed 25 feet.
B. Exceptions.
(1) Any luminaire with a lamp or lamps rated at a total of 1,800 lumens
or less and all flood or spot luminaires with a lamp or lamps rated
at 900 lumens or less may be used without restriction to light distribution
or mounting height, except that if any spot or flood luminaire rated
900 lumens or less is aimed, directed or focused so as to cause direct
light from the luminaire to be directed toward residential buildings
on adjacent or nearby land or to create glare perceptible to persons
operating motor vehicles on public ways, the luminaire shall be redirected
or its light output controlled as necessary to eliminate such conditions.
(2) Luminaires used for public roadway illumination may be installed
at a maximum height of 25 feet and may be positioned at that height
up to the edge of any bordering property.
(3) All temporary emergency lighting needed by the police, the Fire Department
or other emergency services, as well as all vehicular luminaires,
shall be exempt from the requirements of this section.
(4) All hazard warning luminaires required by federal regulatory agencies
are exempt from the requirements of this section, except that all
luminaires used must be red and must be shown to be as close as possible
to the federally required minimum lumen output requirement for the
specific task.
(5) Luminaires used primarily for sign illumination may be mounted at
any height to a maximum of 25 feet regardless of lumen rating.
C. Temporary outdoor lighting.
(1) Any temporary outdoor lighting that conforms to the requirements
of this chapter shall be allowed. Nonconforming temporary outdoor
lighting may be permitted by the Board of Selectmen after considering:
(a)
The public and/or private benefits that will result from the
temporary lighting;
(b)
Any annoyance or safety problems that may result from the use
of the temporary lighting; and
(c)
The duration of the temporary nonconforming lighting.
(2) The applicant shall submit a detailed description of the proposed
temporary nonconforming lighting to the Board of Selectmen, which
shall consider the request at a duly called meeting of the Board of
Selectmen. Prior notice of the meeting of the Board of Selectmen shall
be given to the applicant and the Kennebunkport Lighting Committee.
(3) The Board of Selectmen shall render its decision on the temporary
lighting request within two weeks of the date of the meeting. A failure
by the Board of Selectmen to act on a request within the time allowed
shall constitute a denial of the request.
