A. Applicability. The standards of this section shall not apply to:
1. Individual residential lighting that is not part of a site plan or
plan.
2. Lighting associated with temporary
that have been permitted.
3. Seasonal lighting that is part of customary holiday decorations and annual civic events.
4. Lighting associated with
illumination as set forth in Article 8.
5. Municipal lighting installed for the benefit of public health, safety, and welfare.
B. Lighting plan. Any proposed requiring a site plan or plan shall include, as part of site plan or plan submission, a detailed exterior lighting plan. This plan shall include:
1. Specifications for the lighting fixtures such as: type of unit (cutoff, non-cutoff, glare shields, etc.), lamps (wattage, etc.), electrical load requirements, utility company involved, method of wiring, routing/location of lines, location of lights, and mounting heights.
2. An iso-footcandle plan that shows typical footcandle contours or a point photometric grid that indicates footcandle levels measured at grade across the site. Other information such as: maximum, average, and minimum site footcandles, uniformity ratio (average/minimum), and depreciation factors should also be included.
C. Final acceptance. Before certificates of occupancy are released, the owner/builder must supply the Town with a final letter of certification from the lighting engineer, lighting manufacturer, or authorized lighting contractor verifying that all site lighting is installed according to Town standards, the approved plans, and any applicable conditions.
D. lighting.
1. lighting required. All and sidewalks shall be sufficiently illuminated to ensure the security of the right-of-way and safety of using such areas. To comply with this provision, the applicant shall coordinate with the utility company and the Town to see that all necessary facilities for the eventual installation of lights are put in place.
2. Town responsibility. The Town shall be responsible for requesting the utility company to install lights. Such lights shall be consistent with the Town's standard light package with regard to fixture type, intensity, pole type, length, and spacing.
3. responsibility. The shall be responsible for the placement and operation of necessary lighting in common areas not dedicated to public . The shall also be responsible for the placement and operation of any lights placed in the public right-of-way that are not consistent with the Town's standard lighting package. Such lights shall be approved by the Town Engineer.
E. Site lighting design requirements. All lighting fixtures designed or placed so as to illuminate any portion of a site shall meet the following requirements:
1. Fixture (luminaire). The light source shall be completely concealed within an opaque housing and shall not be visible from any right-of-way. Floodlights may be used in the rear of non-residential that are not adjacent to residential or residentially zoned properties and are not visible from public or private roadways if there are not measurable impacts to neighboring properties. If floodlights are permitted, in addition to meeting the locational restrictions noted above, they shall be installed such that the fixture shall be aimed down at least 45 degrees from vertical. Flood lights and display lights shall be positioned such that any such fixture with a side-to-side horizontal aiming tolerance not to exceed 15 degrees from perpendicular to the right-of-way. Glare shields must be added to reduce glare.
2. Light source (lamp). Only incandescent, LED, fluorescent, metal halide, or induction lighting may be used. High pressure sodium lighting may be used if approved by the permit issuing authority. The same type must be used for the same or similar types of lighting on any one site throughout any master-Planned .
3. Mounting. Fixtures shall be mounted in such a manner that the cone of light directly under the fixture does not cross any property line of the site.
a. All outdoor lighting fixtures shall be located a minimum of ten feet from a property or right-of-way line, and should be kept out of and at least two feet away from any required perimeter or streetscape
, and tree save area. If forward throw fixtures are used the minimum setback distance may be reduced to a minimum of five feet from a property or right-of-way line.
b. Lighting for outdoor display areas, such as auto dealerships, must be located inside the illuminated area or no more than ten feet away from the outside edge of the illuminated area so that the amount of direct glare and the visual field of view does not present a safety hazard to the passing motorist.
4. Mounting heights. Outdoor lighting fixtures shall be designed, located and mounted at heights no greater than:
a. Thirty feet above grade for non-cutoff lights; and
b. Thirty-seven feet above grade for cutoff lights.
c. Mounting height is measured from the finished grade or surface and includes the total height of the fixture, pole, and any base or other supporting
required to mount the lights.
d. All wall packs must be full cut-off.
5. Architectural/site compatibility. Lighting fixtures shall be of a design and size compatible with the of a and adjacent areas, and shall be designed to be an integral part of the entire site.
6. Illumination levels. All site lighting shall be designed so that the level of illumination as measured in footcandles (fc) at any one point meets the standards in the table below. The minimum light level for all illuminated areas shall be no less than 0.2 footcandles maintained. Average level is a not to exceed value calculated using only the area of the site intended to receive illumination. It is recognized that the site lighting of some land may need to be evaluated on a case by case basis, therefore the BOA, via may allow deviations from these standards if it concludes that the objectives underlying these standards can be met without strict adherence to them, provided there are no excessive measurable impacts to adjoining properties that result and it finds that such deviations are more likely to satisfy the standards listed below.

F. Lighting required for specific .
1. Roads,
, sidewalks and parking
. All roads,
, sidewalks and parking
shall be sufficiently illuminated to ensure the security of property and safety of
using such areas and facilities. Where such roads,
, sidewalks or parking
fall on private property, the responsibility for lighting such areas shall fall upon the
.
2. Entrances and exits in nonresidential and multifamily
. All entrances and exits in
used for nonresidential purposes and open to the general public, along with all entrances and exits in multifamily residential
containing more than four units, shall be adequately lighted to ensure the safety of

that incorporates a canopy area over fuel sales, automated bank machines, or similar installations shall use a recessed lens cover that is flush with the bottom surface of the canopy that provides a cutoff or shielded light distribution. Areas under a vehicular canopy shall have an average of 12 footcandles as measured at ground level at the inside of the outside edge of the canopy.
G. Roof lighting.
Commentary: Many businesses use tasteful roof lighting not only to increase the visibility of their establishments, but to add visual
to the nighttime sky of the Town. This section is intended to prevent gaudy, harsh, glaring, loudly contrasting and otherwise distasteful roof lighting within the Garner
.
1. Application.
a. An application for a permit authorizing a
including the
of roof lighting shall include a roof lighting plan containing sufficient information to determine whether the roof lighting, if installed as proposed, will meet the standards and intent of this section.
b. Whenever a roof lighting plan is submitted pursuant to this section, it may be referred to the Planning Commission to obtain the Commission's recommendation on the compliance of the plan with this section.
2. Roof lighting standards.
a. All bulbs or tubing shall be encased so that the bulb is not naked and that direct glare is prevented.
b. Complete outlining of the roof is not permitted.
c. Lights shall not run along the highest peak of a roof line, except that perimeter lighting around the top of a flat roof is allowed.
d. Roof lighting that qualifies as a
under this UDO is prohibited.
H. Excessive illumination.
1. Lighting within any
that unnecessarily illuminates and substantially interferes with the
or enjoyment of any other
is prohibited. Lighting unnecessarily illuminates another
if it clearly exceeds the requirements of this section, or if the standard could reasonably be achieved in a manner that would not substantially interfere with the
or enjoyment of neighboring properties.
2. Lighting shall not be oriented so as to direct glare or excessive illumination onto
in a manner that may distract or interfere with the vision of drivers on such
.
3. Illumination using bare illuminated tubing or strings of lights that completely outline or define property lines, sales areas, roofs, doors, windows or similar areas in a manner that is not primarily for safety purposes is prohibited.
