A. 
The purpose of this Chapter is to provide minimum standards for effective, economical and attractive outdoor lighting in the City. The standards are intended to encourage well-designed, harmonious, appropriate and necessary exterior lighting, through the regulation of the types, kinds, construction, installation and uses of outdoor lighting, which will:
1. 
Provide good, cost efficient, energy efficient lighting in outdoor public places at night and promote safety and security within the City;
2. 
Minimize adverse effects of glare and light trespass, thus protecting neighbors from the consequences of stray light caused by nuisance glare from poorly aimed, misdirected or inadequately shielded light sources;
3. 
Protect drivers and pedestrians from disabling glare caused by non-vehicular light sources that shine directly into their eyes, thereby impairing safe traverse;
4. 
Minimize nighttime light pollution while enhancing nighttime enjoyment of the sky; and
5. 
Enable fair and consistent enforcement of lighting standards and restrictions.
B. 
In adopting these regulations, the Board of Aldermen recognizes and seeks to preserve and enhance the City's distinctive character found in its mature residential neighborhoods and diverse, upscale commercial areas. Furthermore, the Board of Aldermen wishes and endeavors to protect and promote the City's charm and aesthetic qualities and assure Frontenac will be an attractive place in which to live, work and visit.

Words and phrases used in this Chapter shall have the meanings hereinafter set forth:

Light emitted directly from the lamp, off the reflector or reflector diffuser or through the refractor or diffuser lens of a luminaire that is emitted in the general direction of the surface to be illuminated.
DIRECTIONAL DISTRIBUTION LAMP
Any of several different types of lamps which use an integral reflector and usually a glass cover which together provides optical control.
ENCLOSED FIXTURE
Any light fixture which has a glass, acrylic, polycarbonate or screen enclosure of the light source (quartz glass does not meet this requirement) which provides protection from lamp shattering.
FIXTURE
The assembly that houses the lamp or lamps and that includes all or some of the following parts: a housing, a mounting bracket or pole assembly, a lamp holder, a ballast, a reflector or mirror and/or a refractor or lens.
FIXTURE CENTERLINE
For any light source installed above the ground, the path of direct light emitted from the lamp when the lamp is aimed directly downward (e.g., ninety degrees (90°) perpendicular) to the ground.
FLOODLIGHT
Any of several different types of lamps with relatively wide beam angles (greater than thirty degrees (30°)).
FOOT-CANDLE
A unit of illumination of a surface that is equal to one (1) lumen per square foot. For the purposes of these regulations, foot-candles shall be measured at a height of three (3) feet above finished grade.
GLARE
Light emitting from a luminaire with such intensity that it is great enough to reduce the viewer's ability to see and, in extreme cases, cause aversion of vision or momentary blindness.
HEIGHT OF LUMINAIRE
The height as measured by the vertical distance from the ground directly below the center of the luminaire to the lowest direct light emitting part of the luminaire.
HIGH INTENSITY DISCHARGE (HID)
Light sources characterized by an arc tube or discharge capsule that produce light. Typical sources include metal halide, high pressure sodium, mercury vapor and other similar types which emit high lumens per fixture.
INDIRECT LIGHT
Direct light that has been reflected or has scattered off other surfaces, such that the viewer perceives light from a source other than the original lamp source.
LAMP

[Ord. No. 2006-1497 §1, 4-18-2006]
A. 
The following lighting standards shall be applicable to all residential properties within the City:
1. 
All lighting shall be aimed, located, designed, fitted and maintained so as not to create glare that presents a hazard or nuisance to drivers and/or pedestrians, generates nuisance glare or produces prohibited light trespass on neighboring properties.
2. 
Lights must be fully shielded, down directed and screened from adjacent properties in a manner that limits light trespass to one-tenth (0.1) of a foot-candle as measured at the property line.
3. 
Lighting with HID light sources shall be prohibited.
4. 
Up-lighting shall only be 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. Fixture spacing shall be limited to one (1) fixture per one hundred fifty (150) square feet of horizontal area with total lamp wattage not to exceed thirty-five (35) watts.
5. 
Fixture height shall be twelve (12) feet or less unless fully shielded and downward directed with a non-adjustable mounting.
6. 
Landscape lighting is limited to thirty-five (35) watts per fixture per one hundred fifty (150) square feet of landscaped area (as measured in a horizontal plane).

c. 
The light level shall not exceed three (3) foot-candles as measured three (3) feet above finished grade.
