Light pollution obscures the night sky, a resource important
to residents and visitors. Light trespass interferes with the quality
of life and public safety of the community. Standards for outdoor
lighting are intended to control artificial light from non-vehicular
sources that produce glare, light trespass, nuisance light and/or
degrade the night sky. These standards are intended to reduce and
eliminate nuisance glare and light trespass from poorly placed, inappropriate,
misaligned or improperly shielded light sources. It is the further
intent of these standards to conserve energy and resources as well
as to curtail and reverse the degradation of the night sky through
the regulation of the type and use of outdoor lighting while maintaining
night-time safety, utility and security.
(Ord. 1677, 7-19-2010)
All residential and commercial lighting whether on public or
private property installed in the city limits of Kalispell shall comply
with the requirements and specifications established with these regulations.
Lighting within a public or private right-of-way is not within the
scope of these regulations.
(Ord. 1677, 7-19-2010)
(1) All outdoor lighting, including the fixture, pole, and other supporting
elements, shall be designed to complement the overall architectural
appearance of the site and prevent excessive glare.
(2) Low voltage landscape lighting will be allowed provided it is directed
toward the object or building and does not leave the perimeter of
the site or contribute to light trespass.
(3) Nothing herein shall be deemed to prohibit the installation of minimum
emergency lighting standards required by the applicable building and/or
fire codes.
(4) When practical, timing mechanisms and photo cells shall be used to
reduce light levels and conserve energy during non-operational hours.
(5) Mercury vapor lights are prohibited because of the poor color spectrum,
light intensity and inefficient energy use. Low pressure or high pressure
sodium lights and metal halide are encouraged rather than the use
of fluorescent lights.
(6) Light fixtures or lamps shall be shielded in such a manner so that
the light emitting surface is not visible and to direct incident rays
away from all adjacent property.
(7) Any light fixture must be placed in such a manner so that no light
emitting surface is visible from any residential area or public/private
roadway, walkway, trail or other public way when viewed at ground
level.
(8) Exposed bulbs used for ornamental purposes that do not exceed the
equivalent of 15 watts incandescent are exempted from shielding requirements.
(Ord. 1677, 7-19-2010; amd. Ord. 1824, 3-18-2019)
(1) Lights mounted on poles shall not be taller than 25 feet (pole height
to be calculated from grade to the top of the pole structure).
(2) The level of lighting shall not exceed 0.3 foot candles at any residential
property line or 1.0 foot candles at any nonresidential property line,
except that the measurement along any right-of-way shall be taken
from the curb line, or, if there is no curb, the edge of the asphalt.
Measurements shall be taken from ground level. If a side or rear property
line is adjacent to a parking lot, the maximum foot candle measurement
may be exceeded provided that the increase is otherwise designed to
meet the intent of this Zoning Ordinance.
(3) Light (including, but not limited to, pole lights, floodlights, wall
lights, etc.) shall have external shielding or shall be directed and
angled so that no light is visible above a 90 degree angle measured
from a vertical line from the center of the lamp (i.e., shall be a
full cutoff fixture) and shall not shine onto any adjacent public
right-of-way or adjacent property.
(4) Roof illumination is not allowed.
(Ord. 1677, 7-19-2010; amd. Ord. 1771, 6-6-2016)
At the time of site plan approval by the Kalispell Site Development
Review Committee, the applicant must supply a lighting plan in accordance
with these regulations and shall demonstrate conformance with these
standards. At a minimum the lighting plan shall include:
(1) Manufacturer specifications regarding the light fixture, proposed
locations, mounting heights and direction of all exterior lighting.
(2) If the building, signage or landscaping is proposed to be lit, relevant
drawings shall be provided showing the type, location and direction
of the light fixture.
(3) Photometric data of all parking lot lighting and other descriptive
information on the fixtures and/or a computer generated photometric
grid showing foot candle reading every 10 feet within the property
or site and 10 feet beyond the property boundaries.
