(A) General. No person, firm or corporation shall install or erect any floodlight, searchlight, security light or other form of light source in such a manner that the light rays from such device fail to conform with the terms and conditions of this code. Further, no person, firm or corporation shall install or erect, any floodlight, searchlight, security light or other type of light source in such a manner that the light therefrom may distract the attention of any vehicle driver from the operation of a vehicle in a safe and prudent manner. In all properties the modification or replacement of any permanent outdoor lighting fixtures shall comply with these regulations.
(B) Light trespass. The maximum illumination at five feet inside an adjoining residential lot or public right-of-way or beyond, from an artificial light shall be no greater than 0.054 lux (lumens/meter²). Said illumination likewise measured inside an adjoining commercial or industrial lot or on a public street, or beyond, shall not exceed 1.08 lux. No line of sight to a glaring light source is permitted from five feet or more inside a residential property line or public right-of-way property line by an observer viewing from a position that is level with or higher than the ground below the fixture. Total lux can be calculated by the following formula: B = L/4.d2, where: B = brightness expressed in lux (lumens/m2); L = fixture light emission expressed in lumens; and d = Distance in meters from the light source (3.28 feet = 1 meter).
(C) General lighting design.
(1) The bulbs in outdoor light fixtures emitting from 600 to 1,200 lumens shall be frosted glass or covered by frosted glass or other similarly translucent cover.
(2) An outdoor light fixture emitting more than 1,200 lumens, except motion detector activated lighting, shall be full cutoff and fully shielded to an observer at the property line.
(3) A spotlight of less than 1,800 lumens need not be full cutoff or covered by a translucent cover if its center beam is aimed at a point not beyond any property lines and no higher than 45 degrees below horizontal, and is motion detector activated and cycles off after five minutes.
(4) Generally, lighting fixtures should not be located closer to the property line than a distance equal to three times the fixture’s mounting height above grade at the property line.
(5) No searchlights, laser lighting or lights that pulse, flash, rotate or simulate motion shall be used for advertising or promotions.
(6) Emergency lighting and traffic control lighting is exempt from these general lighting requirements.
(7) Tower lighting shall not be permitted unless required by the FAA. Required lighting shall be of the lowest allowed intensity and red unless specifically forbidden under FAA requirements.
(8) At the close of business, all lighting shall be reduced to a level not greater than those described in division (D)(2) below.
(9) The American flag may be illuminated by up to three upward facing spotlights.
(D) Specific lighting requirements.
(1) Landscaping. When landscaping is to be illuminated in Commercial or Multiple- Family Residential-2 Zoning Districts, the Board shall first approve a landscape lighting plan that presents the purpose and objective of the lighting, shows the location of all lighting fixtures and what landscaping each is to illuminate, and demonstrates that the installation will not generate excessive light levels, cause glare or direct light beyond the landscaping into the night sky.
(2) Parking lot lighting. Parking lot lighting shall be designed to provide the minimum lighting necessary to ensure adequate vision and comfort in parking areas, and to not cause glare or direct illumination onto adjacent properties or streets.
(a) All lighting fixtures serving parking lots shall be cut-off fixtures.
(b) Mounting heights of lighting fixtures shall not exceed 20 feet.
(c) The minimum illumination level shall not exceed 4.3 lux. The ratio of the average illumination to the minimum illumination shall be 4:1.
(3) Lighting of walkways, bikeways and parks. Where special lighting is to be provided for walkways, bikeways or parks, the following requirements shall apply.
(a) The walkway, pathway or ground area shall be illuminated to a level of no more than 5.4 lux.
(b) The vertical illumination levels at a height of five feet above grade shall be no less that 5.4 lux.
(c) Lighting fixtures shall be designed to direct light downward, and light sources shall have an initial output of no more than 1,000 lumens.
(4) Lighting of gasoline station or convenience store aprons and canopies. Lighting levels on gasoline station or convenience store aprons and under canopies shall be adequate to facilitate the activities taking place in such locations. Lighting of such areas shall not be used to attract attention to the business. Signs allowed under local ordinances shall be used for that purpose.
(a) Areas on the apron away from the gasoline pump islands used for parking or vehicle storage shall be illuminated in accordance with the requirements for parking areas set forth elsewhere in this section. If no gasoline pumps are provided, the entire apron shall be treated as a parking area.
(b) Areas around the pump islands and under canopies shall be illuminated so that the minimum horizontal luminance at grade level shall not exceed 60 lux. The ratio of average to minimum luminance shall be no greater that 4:1.
(c) Light fixtures mounted on canopies shall be recessed so that the lens cover is recessed or flush with the bottom surface of the canopy and/or shielded by the fixture or the edge of the canopy so that light is restrained to no more than 85 degrees beyond the vertical plane.
(d) Lights shall not be mounted on the top or sides of the canopy and the sides of the canopy shall not be illuminated.
(5) Outdoor sports or recreation fields or performance areas. Lighting of outdoor recreational facilities (public or private), such as, but not limited to, football fields, soccer fields, baseball fields, softball fields, tennis courts, driving ranges, special event or show areas, shall meet the following conditions.
(a) All fixtures used for such lighting shall be fully shielded with 15-degree cutoff.
(b) All lighting of facilities covered in this section is prohibited after 11:00 p.m., except as noted below.
1. Illumination of the playing field, court, track or event site, after 11:00 p.m. is prohibited except to conclude a scheduled event that was scheduled to be completed before 11:00 p.m. that circumstances prevented concluding before 11:00 p.m.
2. The hours of operation for the lighting system for any game or event shall not exceed one hour after the end of the event. When the event schedule places this time after 11:00 p.m., a permit from the town shall be obtained.
(c) Lighting levels for outdoor performance areas, sport and recreation facilities, and playfields shall not exceed by more than 5% the Illuminating Engineering Society of North America’s (IESNA) published standards for the proposed activity.
(E) Street lighting.
(1) Generally.
(a) Unless otherwise approved by the Board, the developer of new areas within commercial or multiple-family residential.
(b) Zoning districts shall be required to design and construct street lighting systems in accordance with accepted guidelines and professional standards or have the street lighting system designed and constructed by the current power company. The plans shall be reviewed and approved by the Board before construction. All costs associated with associated with furnishing and installing the street lighting systems will be borne by the developer. The town shall assume ownership of the streetlight system on town streets after inspection and testing of the system is complete and the system is functional and approved by the town in all respects. The plans must be designed by and sealed by a professional engineer licensed in the state who is qualified in the design of electrical streetlight systems. In the event a conflict exists between these requirements, the more stringent applies.
(2) Location.
(a) Spacing.
1. Poles and fixtures shall be located on the front property line.
2. The light poles and fixtures shall be located at 100-foot spacing from pole to pole, on alternating sides of the street (staggered) or as approved by the Board. The Board may waive this requirement in residential zones.
3. A minimum of two light poles and fixtures, staggered across the intersection, shall be required at all intersections. The Board shall approve the final fixture location. The Board may waive this requirement in residential zones.
