The following restrictions shall apply to any outdoor lighting located in any district on parcels where there are parking spaces for five or more vehicles, or where a building, sign or electrical permit is required for the installation of lighting fixtures.
(A) Submission of lighting plan. For any parking area for five or more vehicles, a lighting plan shall be provided. A lighting plan may also be required, at the determination of the Village Engineer, when a building, sign or electrical permit application for lighting fixtures is filed. The lighting plan shall provide the following information, at a minimum:
(1) A photometric plan showing the proposed intensity levels of the lighting throughout the site, indicating foot-candle measurement shall be provided. The lighting plan shall include the property lines and right-of-way lines for the site, and shall indicate all site lighting in the evaluation. The initial output of lamp fixtures, as defined by the manufacturer, is the value to be considered in the intensity analysis.
(2) The lighting plan shall indicate the locations of each of the proposed fixtures.
(3) The lighting plan shall indicate the minimum, maximum and average intensity/illumination for the site.
(4) Details of all proposed outdoor lighting fixtures shall be provided, indicating manufacturer, model and style of the fixture. A graphic representation of the fixture is requested. The fixture lamp type (i.e. low pressure sodium, metal halide, etc.) shall be indicated on the proposed plans.
(5) The proposed height of the lighting fixtures shall be indicated.
(6) The hours of use of the lighting fixture shall be indicated on the plans.
(B) Height. All outdoor lighting shall be designed, located, and mounted at heights no greater than 12 feet above grade for non-cutoff lights and 18 feet above grade for cutoff lights. The following guidelines are provided based on the intensity of the proposed use. Heights in excess of these guidelines may be approved by the Planning and Historic Preservation Commission when due cause is indicated by the property owner.
(1) Height range by activity level:
(a) Low: 10 ft. to 15 ft.
(b) Medium: 10 ft. to 18 ft.
(2) Examples of activity levels for open parking facilities:
(a) Low. Residential, education facilities, churches, local commercial uses.
(b) Medium. Community and neighborhood shopping centers, office parks, hospitals, community facilities (cultural, civic, recreational).
(C) Illumination. Outdoor lighting shall be designed and located with a maximum illumination of 0.5 foot-candles at the property line. Lighting for parking areas and where security lighting is needed shall have a minimum of 0.5 foot-candles. The guidelines for illumination levels listed below are based on the activity levels described herein. Lighting in excess of these guidelines may be approved by the Planning and Historic Preservation Commission when due cause is indicated by the property owner.
(1) Average illuminance by activity level:
(a) Low: 1.0 foot-candle; or
(b) Medium: 2.0 foot-candle.
(2) Maximum illumination (foot-candles) by activity level:
(a) Low: 5.0 foot-candle; or
(b) Medium: 10.0 foot-candle.
(3) Uniformity of illumination (maximum/minimum foot-candle ratio) should not exceed 15:1.
(4) Illumination of access drive should not exceed average foot-candles maintained at adjacent public road.
(D) Light trespass. Light trespass is any form of artificial illumination emanating from a light fixture (or illuminated sign) that penetrates other property and creates a nuisance. A lighting plan shall be provided by the property owner proposing the installation of outdoor lighting fixtures and shall meet the following minimum standards for light trespass:
(1) Outdoor light fixtures shall be directed so that there will not be any objectionable direct glare source visible from any property, and shall be properly installed and thereafter maintained.
(2) At a height of five feet above the property line of the subject property, illumination from light fixtures shall not exceed 0.5 footcandles in a vertical plane on adjacent property.
(3) Appropriate fixture lamp types and shielding shall be installed to prevent light trespass onto adjacent property.
(E) Shielding. All outdoor lighting for non-residential uses shall be located, screened, or shielded so adjacent lots located in residential districts are not directly illuminated. Shielding may also be required for high intensity light fixtures to prevent glare to adjacent uses, public right-of-ways, and drivers. Perimeter lighting should be cut-off fixtures to prevent light trespass onto adjacent properties.
(F) Color and glare. No outdoor lighting shall be of such an intensity or color distortion as to cause glare or to impair the vision of drivers, pedestrians or adjacent properties. Shields and/or filters are required for light fixtures with high intensity and glare potential. All lighting shall be provided by cutoff fixtures with no extended/projected lenses.
(G) Factors for evaluation. The following factors shall be considered in the evaluation of lighting plans:
(1) Pole height;
(2) Type of luminaries;
(3) Site coverage - average maintained;
(a) Maximum: Minimum
(b) Average: Minimum
(5) Intensity at property line.
(H) Location. Outdoor lighting need not comply with the yard requirements of each district, except that, for visibility across corner lots, no such light shall obstruct vision within the sight triangle formed by the points 30 feet from the intersection along the street right-of-way lines.
(1) All outdoor lighting fixtures producing light directly by the combustion of fossil fuels, such as kerosene lanterns or gas lamps, are exempt from the requirements of this section.
(2) Holiday lighting shall be exempt from the requirements of this section.
(3) All temporary emergency lighting needed by Police or Fire Department or other emergency services, as well as all vehicular luminaires, shall be exempt from the requirements of this section.
(J) Special approval. Search lights, laser source lights, or any similar high-intensity light shall not be permitted, except in emergencies by Police and Fire Department personnel or at their discretion, unless a temporary sign/use permit is issued by the Building Official.
(K) Modifications. Should any outdoor light fixture or the type of light source therein be changed after the permit has been issued, a change request must be submitted to the Village Engineer for his approval, together with adequate information to assure compliance with this section, which must be received prior to substitution.
