All lighting shall follow the guidelines as
amended by the IESNA - Illuminating Engineering Society of North
America.
A. Height. The intent is to maintain a safe, secure,
and attractive environment using adequate and attractive lighting.
Exterior lighting shall serve as a security measure and increase general
visibility. The lighting of buildings, landscaping, driveways, signs
and other exterior uses of lighting shall be designed to minimize
the light and glare on adjacent neighborhoods and roadways. Lighting
along the main roadways should be geared to pedestrians, to encourage
main street activity into the evening hours.
(1) Required standards.
(a)
Pole-mounted fixtures in vehicular use or pedestrian
areas shall not exceed a mounting height of 12 feet, and such poles
shall be located so as not to be a hazard in the path of travel for
pedestrian or vehicular access.
(b)
Wall-mounted lighting fixtures shall not exceed
the height limits set for the pole-mounted fixtures in their respective
use areas, and shall be provided in a manner that will minimize glare
to vehicular traffic.
(c)
Outdoor lighting may exceed 12 feet in height
if it meets one or more of the following criteria:
[1]
Building-mounted lighting directed back at a
sign or building facade; or lighting on above-grade decks or balconies
which shall be fully shielded.
[2]
Additional lighting needed for highway or intersection
safety as required by State Highway Administration.
B. Illumination. The intent is to maintain a safe, secure,
and attractive environment using adequate and attractive, and functional
lighting.
(1) Required standards.
(a)
All outdoor lighting shall provide illumination
at ground level not to exceed the range set below:
[1]
Average illumination: 0.3 footcandles.
[2]
Maximum illumination: 0.5 footcandles.
(b)
In addition, outdoor lighting shall be designed
so that any overspill be minimized, but if necessary and approved
by the Planning Commission, lighting onto adjacent properties shall
not exceed one-half footcandle vertical and one-half footcandle horizontal
illumination to the adjacent properties or structures.
(c)
All lighting shall be glare-free and shielded
from the sky and adjacent residential properties and structures, either
through exterior shields or through optics within the fixture.
(d)
Lighting shall not be used to attract attention
to a business, but to provide reasonable levels of lighting for safety
and identification.
(e)
Lighting levels shall comply with Illuminating
Engineering Society of North America's Recommended Practices and Design
Guidelines, latest edition.
(f)
Safety lighting shall be provided at building
entrance and doors sufficient to illuminate the doorway.
C. Design and compatibility. The design of exterior lighting
fixtures shall enhance and complement the character of a specific
building or space, and must reflect the traditional elements of Dagsboro.
(1) Required standards.
(a)
Lighting styles of both poles and fixtures must
be of a style compatible with the design and architectural style of
the buildings and facilities illuminated. Lighting fixtures must be
appropriate for the type of development proposed.
(b)
Pedestrian scale lighting may also be accomplished
with fixtures that are mounted on buildings or located to accent architectural
or landscape features. Such fixtures should be designed to enhance
the overall architecture of the building, provide lighting for pedestrians
and not damage historic materials.
D. Discouraged lighting.
(1) The use of uplighting should be avoided to minimize
light pollution of the night sky and to prevent light trespassing
onto adjacent properties. However, uplighting to wash or accent a
sculpture or art work may be approved by the Planning Commission.
E. Prohibited lighting.
(1) Flashing lights: Any lights that flash, move, revolve,
rotate, scintillate, blink, vary in intensity or color, or use intermittent
electrical pulsation.
(2) Outdoor string of lights, including but not limited
to those outlining lot lines, or outdoor display or sales lots.
(3) Luminous colored-tube lighting.
(4) The following lighting fixtures are prohibited in
all new or redevelopment projects:
(d)
Other non-fully shielded fixtures.
(5) Colored lighting unless specifically approved by the
Planning Commission.
F. Exempt lighting.
(1) The following lighting is exempt from lighting standards:
(b)
Construction or emergency lighting.
(c)
State approved lighting needed for highway safety,
and approved traffic control devices.
