Sec. L-II 3.8 Communication Towers and Facilities
F. DESIGN STANDARDS
6. Lighting for communication facilities shall be limited as follows:
a. All approved lighting shall be shielded or directed on site to
minimize off-site light spill except for lighting required by the
Federal Aviation Administration.
b. In residential zones, lighting shall be limited to security lighting
that
is manually-operated or motion-detector controlled.
Sec. L-II 3.11 Home Businesses
B. STANDARDS
5. The business shall not alter the appearance of the premises,
including but
not limited to lighting, signage and outdoor activity.
Sec. L-II 3.12 Model Homes, Temporary
C. STANDARDS
5. All lighting shall comply with the standards of Section L-II 4.2.8. Page 166 Sec. L-II 4.2.8 Lighting
A. PURPOSE. This section establishes standards to provide for
efficient, safe and
attractive outdoor lighting while minimizing nighttime light pollution
and energy
waste.
B. APPLICABILITY. Lighting standards shall apply to Development
Permits, Use
Permits, and subdivisions, unless otherwise excepted in this section.
C. DEFINITIONS.
1. Fully shielded – a technique or method of construction and/or
manufacture
which does not allow any light dispersion to shine above the horizontal
plane from the lowest light emitting point of the light fixture and
which
precludes visibility of the light source.
2. Glare – artificial light that causes annoyance, discomfort or loss
of visual
performance and visibility.
3. Light pollution – artificial light which, through uplighting,
detrimentally
affects the clarity of the night sky, or causes undesirable glare,
skyglow, or
light trespass.
4. Light trespass – artificial light that produces an unnecessary and
unwanted illumination of an adjacent property.
5. Skyglow – the glow above brightly lit developed areas, visible in
the night
sky, that occurs when light shines into the sky and is reflected off
clouds,
particles of moisture or dust suspended in the atmosphere.
6. Strip Light-a continuous band of light not necessary for public
safety.
D. STANDARDS. All outdoor lighting shall meet the following standards:
1. A lighting plan shall be submitted with all discretionary projects
that
propose to install outdoor lighting. Plans shall depict the location,
height
and positioning of all light fixtures and shall provide a description
of the
type and style of lighting proposed, including pole or building mounted
area lights and sign lights.
2. All outdoor light fixtures shall be fully shielded to prevent the
light source
or lens from being visible from adjacent properties and roadways, except
for the following:
a. Airport lighting required for the safe and efficient movement of
aircraft during flight, take off and landing.
b. Outdoor light fixtures used for outdoor recreational facilities when
such shielding would cause an impairment to the visibility required
in the intended recreational activity. In such cases, partially
shielded fixtures and directional lighting methods shall be utilized to
limit light pollution, glare and light trespass, without diminishing the
performance standards of the intended recreational activity.
3. Externally illuminated signs and building identification shall use
topmounted
light fixtures which shine light downward.
4. The use of façade, or “wash” lighting is limited to public
buildings, or
buildings with historic importance. Façade lighting may be
approved only
when it is determined that it is compatible with the level of lighting
in the
immediate area and where it will not generate excessive illumination,
skyglow or glare.

5. Light fixtures mounted on the canopies of service stations, on
convenience stores, restaurants, or other similar businesses, shall be
recessed so that the lens cover is recessed or flush with the bottom
of the canopy so that light is restrained to no more than 85 degrees
from
vertical. As an alternative or supplement to recessed ceiling lights,
indirect lighting may be used where light is beamed upward and then
reflected down from the underside of the canopy. In this case fixtures
must be shielded so that direct illumination is focused exclusively on
the
underside of the canopy. Lights shall not be mounted on the top or sides
(fascia) of the canopy, and the sides (fascia) of the canopy shall not
be
illuminated.

6. Use fixtures with high efficiency lamps. High pressure sodium, and
mercury vapor light fixtures are prohibited.
7. Light poles shall be restricted to a maximum of 20’ in height except
that on
parcels adjacent to residential or rural zoning districts, the maximum
height shall be restricted to 15’.
8. All exterior lighting shall be maintained as installed.
9. Lighting shall be turned off between 11 p.m. and sunrise, except for
those
businesses operating during these hours or where a safety or security
need is clearly demonstrated.
10. Lighting systems, other than signs, shall include dimmers, occupancy
sensors, time controls or separate circuits, to allow sections of the
lighting
to be turned off as needed.
11. Security lighting fixtures shall be shielded and aimed so that
illumination is
directed only to the designated area and not cast on other areas. The
use
of motion or heat sensors may provide greater security than continuous
lighting and are the preferred alternative to continuous nighttime
lighting.
12. The use of searchlights, lasers, strip lights, flood or spot lights
is
prohibited. Page 169 Sec. L-II 4.2.9 Parking

7. Lighting. When lighted, all signs shall be illuminated by
continuous, nonpulsating,
shielded and stationary light sources, using light fixtures, which
direct external light sources at the sign so as to illuminate only the
sign
face. Any external spot or flood lighting shall be arranged so that the
light
source is screened from direct view. ...
