(a)
Applicability.
The regulations of this section shall apply to all uses, except residential uses. Where any change is made to a site requiring an improvement location permit or existing light fixtures are replaced, site lighting shall be upgraded to comply with the regulations of subsection (c) below.
(b)
Lighting intensity.
Outdoor lighting for all nonresidential uses shall be fully shielded to reduce glare and shall be arranged to reflect light away from all adjacent residential districts or uses. Light levels on a site that is subject to an improvement location permit under this ordinance shall comply with the limits specified in
Table 10.1.
(1) Any outdoor sales areas, the maximum illumination may be increased to 15 footcandles, provided the illumination limits at the property line are not exceeded.
(2) Shall not apply to ornamental street lighting, public streetlights or driveway/intersection lighting necessary for pedestrian and traffic safety.
(3) The light level along a nonresidential property line may be increased to up to five (5) footcandles where there are shared access/vehicular connections with the adjacent use, or the adjacent use is a similar use. Example would be two commercial districts sharing a common boundary.
(4) Lighting levels may be reduced to half (0.5) footcandle with a uniformity ratio of not more than ten to one (10:1) after 12:00 P.M., or after established hours of operation.
(5) The required minimum illumination shall only apply to the developed portion of the site containing buildings, drives and parking lots.
(6) The minimum illumination levels shall not apply to portions of the site that are fenced to restrict public access, such as storage yards.
(c)
Light fixtures.
(1) All fixtures shall be light-emitting diode (LED) or better quality/efficiency light.
(2) Outdoor lighting in all zoning districts shall be directed toward and confined to the ground areas of lawns or parking lots except as noted elsewhere in this section.
(3) Lighting shall utilize cutoff fixtures that are recessed sufficiently such that the light source is not visible from off-site.
(4) The requirement for cutoff fixtures shall not apply to historic or traditional style ornamental lights and street lighting.
(5) Floodlight type fixtures shall not be permitted except for building accent and sign lighting.
(d) Fixture height.
Light fixtures shall have a maximum height of 40 feet where not adjacent to residential. Where located within 200 feet of a residential district, the maximum height of a light fixture shall not exceed 18 feet.
(e)
Signs.
Illumination of signs shall be directed or shielded downward so as not to interfere with the vision of persons on the adjacent highways or adjacent property. Signage lighting shall be subject to the lighting intensity limits specified in
ARTICLE 12: Signs Regulations.
(f)
Constant light.
Illumination shall not be of a flashing, moving or intermittent type. Artificial light shall always be maintained stationary and constant in intensity and color when in use. Sign illumination shall only be allowed as provided for in
§ 12.06(d) Illumination.
(g) Luminous tube (neon) and exposed bulb lighting.
Luminous tube (neon) and exposed bulb fluorescent lighting is prohibited as an architectural detail on all buildings (ex. along the roofline and eaves, around windows, etc.). Internally illuminated architectural bands or features shall be allowed where the light source is not directly visible. Neon lighting is permitted as part of a sign meeting the requirements of
§ 12.06(d) Illumination.
(h) Any site plan application for new or revised lighting shall include a photometric plan overlaid on the site plan illustrating the proposed layout and footcandles of site lighting. The following are required for review:
(1) Lighting plan showing light pole and fixture locations and type designations;
(2) Photometric plan showing horizontal luminance levels in a point by point format with contour lines. Canopy lighting will also be included in luminance levels;
(3) Lighting manufacturers equipment specifications and data sheets; and
(4) Any other presentations required to convey the intent of the design.
