Section 26.575.150, Lighting, is hereby amended by replacing, in total, the
language in said Section with the following text:
Supplemental Regulations, 26.575.150 Outdoor Lighting
f".
A. Intent and Purpose. The City of Aspen has experienced a significant increase in
the use of exterior illumination. City residents' value small town character and the
qualities associated with this character, including the ability to view the stars against a
dark sky. They recognize that inappropriate and poorly designed or installed outdoor
lighting causes unsafe and unpleasant conditions, limits their ability to enjoy the
nighttime sky, and results in mmecessary use of electric power. It is also recognized that
some exterior lighting is appropriate and necessary.
This Section is intended to help maintain the health, safety, and welfare of the residents
of Aspen through regulation of exterior lighting in order to:
a. promote safety and security;
b. help preserve the small town character;
c. eliminate the escalation of nighttime light pollution;
d. reduce glaring and offensive light sources;
e. provide clear guidance to builders and developers;
f. encourage the use of improved technologies for lighting;
g. conserve energy; and,
h. prevent inappropriate and poorly designed or installed outdoor lighting.
B. Applicability. The lighting standards of this Section shall be applicable to all
outdoor lighting within the City of Aspen. Existing outdoor lighting shall be considered
legal non-conforming lighting for one year from the adoption date of this ordinance.
C.
Definitions.
(a) Fully Shielded Light: light fixtures shielded or constructed so that no light
f"
rays are directly emitted by the installed fixture at angles above the horizontal plane as
f". certified by a photometric test report. The fixture must also be properly installed to
effectively down direct light in order to conform with the definition.
(b) Foot-candles: a unit of illumination of a surface that is equal to one lumen
per square foot. For the purposes of these regulations, foot-candles shall be measured at a
height of 3 ft. above finished grade.
( c) Fixture Height: height of the fixture shall be the vertical distance from the
ground directly below the centerline of the fixture to the lowest direct light emitting part
of the fixture.
(d) High Intensity Discharge Light Source (HID): Light sources characterized
by an arc tube or discharge capsule that produces light, with typical sources being metal
halide, high pressure sodium, and other similar types which are developed in accordance
with accepted industry standards.
( e) Point Light Source: the exact place from which illumination is produced
(i.e., a light bulb filament or discharge capsule).
(f) Light Trespass: the shining of light produced by a light fixture beyond the
boundaries of the property on which it is located.
,I""""'.
D. Lighting Plans.
(a) An outdoor lighting plan shall be submitted in conjunction with
applications for subdivision, planned unit development, development within any
environmentally sensitive area, special review application, and building permit
application for a commercial or multi-family building. Such lighting plans shall be
subject to establishment and approval through the applicable review processes. Said
lighting plan shall show the following:
(1) The location and height above grade oflight fixtures;
(2) The type (such as incandescent, halogen, high pressure sodium)
and luminous intensity of each light source;
(3) The type of fixture (such as floodlight, full-cutoff, lantern, coach
light);
(4)
Estimates for site illumination resulting from the lighting, as
measured in foot-candles, should include minimum, maximum and
average illumination. Comparable examples already in the
community that demonstrate technique, specification, and/or light
level should be provided if available to expedite the review
process; and
,~
~
(5)
Other information deemed necessary by the Community
Development Director to document compliance with the provisions
of this Article.
(b) Single family and duplex building shall be in compliance with the
standards of Section 26.575.090.
E. Non-Residential Lighting Standards. The following lighting standards shall be
applicable to all non-residential properties including mixed uses:
(a) Outdoor lighting used to illuminate parking spaces, driveways,
maneuvering areas, or buildings shall conform to the definition for "fully shielded light
fixtures" and be designed, arranged and screened so that the point light source shall not
be visible from adjoining lots or streets. No portion ofthe bulb or direct lamp image may
be visible beyond a distance equal to or greater than twice the mounting height of the
fixture. For example, for a fixture with a mounting height of twelve (12) feet, no portion
of the bulb or direct lamp image may be visible from twenty-four (24) feet away in any
direction. The light level shall not exceed 10 foot-candles as measured three feet above
finished grade. Exemptions may be requested for areas with high commercial,
pedestrian, or vehicular activity up to a maximum of 20 foot-candles.
~
(b) Qutdoor lighting shall be 12 ft. or less in height unless it meets one or
more of the following criteria:
. Fully shielded with a non-adjustable mounting; or
. Lighting for parking and vehicle circulation areas in which case heights up to a
maximum of20 ft. may be allowed; or
. Building mounted lighting directed back at a sign or building fa9ade; or
. Lighting on above grade decks or balconies which shall be fully shielded.
(c) All light sources which are not fully shielded shall use other than a clear
lens material as the primary lens material to enclose the light bulb so as to minimize glare
from that point light source. Exceptions may be allowed where there is a demonstrated
benefit for the community determined through the exemption process listed in this
section.
(d) High Intensity Discharge (HID) light sources are allowed with a maximum
wattage of 175 high pressure sodium (HPS) and 175 watt metal halide (coated lamp -
3,000 degrees Kelvin). Standards for other HID light sources may be established by the
City for new technology consistent with the above restrictions.
i"""",
(e) Spacing for security and parking lot light fixtures that are pole mounted
shall be no less than 75 ft. apart. Decorative fixtures (which are also fully shielded) are
allowed to maintain a 50 ft. fixture spacing. Wall mounted fixture spacing for security
~
lighting shall be no less than 50 ft. measured horizontally. Decorative fixtures directed
back toward a building face shall be exempt from this spacing requirement when shielded
and shall not exceed 50 watts. Decorative fixtures that are not shielded shall maintain a
minimum spacing of25 ft. and shall not exceed 50 watts. Where security lighting is a
combination of pole and wall mounted fixtures, minimum spacing shall be 75 ft. and a
maximum of 150 ft.
(f) Pole mounted fixtures shall be limited to two light sources per pole.
(g) Mixed use areas that include residential occupancies shall comply with the
residential standards on those floors or areas that are more than 50% residential based on
square footage of uses.
(h) Up-lighting is only permitted if the light distribution from the fixture is
effectively contained by an overhanging architectural or landscaping element. Such
elements may include awnings, dense shrubs, or year-round tree canopies, which can
functionally contain or limit illumination of the sky. In these cases the fixture spacing is
limited to one fixture per 150 sq. ft. of area (as measured in a horizontal plane) and a total
lamp wattage within a fixture of 35 watts.
(i) Up-lighting of flags is permitted with a limit of two fixtures per flag pole with
a maximum of 150 watts each. The fixtures must be shielded such that the point source is
not visible outside of a 15-ft. radius.
r

shall not exceed a maximum of 20 candles under the canopy.

maximum of 20 ft. may be allowed; or
. Building mounted lighting directed back at a sign or building fa9ade; or
. Lighting on above grade decks or balconies which shall be fully shielded.

c) c) the light source or fluorescent (or compact fluorescent) to eliminate
excess electricity consumption.
5. Lights must be fully shielded, down directed and screened from adjacent properties in
