A. Lighting: Lights shall be installed in all parking areas containing five (5) or more parking spaces and shall be illuminated between dusk and dawn whenever said premises are open for operation. Open for operation shall be any time that a retail business is open for the sale of goods or services or a retail or office actually has employees working within or upon said premises, other than guards, watchmen, or home occupation. For all parking areas with more than twenty (20) parking spaces, the illumination may be provided through the use of pole mounted light fixtures. Building mounted fixtures shall be primarily for aesthetic and security purposes and shall comply with general standards as noted below.
B. Definitions:
FULL CUTOFF TYPE FIXTURE: A luminaire or light fixture that by the design of the housing, does not allow any light dispersion or direct glare to shine above a ninety degree (90°), horizontal plane from the base of the fixture. Full cutoff fixtures must be installed in a horizontal position as designed, or the purpose of the design is defeated, and disability glare will result.
LIGHT TRESPASS: Light from an artificial light source that is intruding into or spills over to adjoining sites, streets, public and private property.
STRAY LIGHT: Produced within the eye by luminance source (usually light source) within the field of view.
UPLIGHTING: Any light source that distributes illumination above a ninety degree (90°) horizontal plane.
C. General Standards:
1. Site lighting shall include all lighting on property, other than lighting within a fully enclosed building.
2. Site lighting fixtures shall be compatible with the building design and the adjoining landscape and shall not be used in such a manner as to turn the building itself into "signage".
3. Parking lot poles/fixtures of the same style, height, color and intensity of lighting shall be used throughout the development area. Varying styles of fixtures may be permitted if it is demonstrated that the styles contribute to an overall theme for the area.
4. Site lighting shall not result in light trespass by spilling over to adjacent sites or properties.
5. Site lighting shall not result in disability glare that is directed toward or reflected onto adjoining properties.
6. Site lighting shall not result in disability glare that is directed toward or reflected onto streets, or interior drives where such glare could negatively impact vehicular or pedestrian safety.
7. Except when displaying the flags of the United States Of America, state of Illinois or village of Sherman or as may be provided elsewhere in this section, site lighting shall at no time be directed upward (uplighting), in a radiating pattern and/or moving or sweeping pattern, or at any angle which will light surfaces other than building walls, parking or pedestrian areas, and landscaped area, and shall not create lighting patterns which will direct light toward residential areas.
8. All site lighting shall be installed utilizing underground cable.
9. Except where otherwise provided, fixture heads shall be of full cutoff type which controls the lighting pattern and shields abutting property from direct view of the light source.
10. Site lighting, other than security lighting, shall be turned off when a facility is closed, vacant or otherwise occupied solely by security employees.
11. Outdoor display lots for vehicles and similar sales facilities shall reduce display fixture illumination within thirty (30) minutes after closing so the remaining illumination level is sufficient for security purposes only; however, that any illumination used after eleven o'clock (11:00) P.M. shall be reduced to levels sufficient for security purposes only.
D. Plan Submission Requirements: Detailed drawings of all exterior light fixtures including the angle at which they are mounted, in relationship to grade and a site plan showing their location shall be submitted with each building permit application, of which the light fixtures are a part of.
A photometric pattern, showing the foot-candle value at all property lines shall be submitted within ninety (90) days following the application of each building permit, if the scope of work includes the installation of exterior lighting. (Ord. 2011-8A, 5-17-2011)
