[Adopted 3-20-2007 by Ord. No. 2007-5]
The regulation of outdoor lighting is necessary to prevent glare, light trespass (nuisance light) and/or sky glow from misdirected or excessive artificial light emanating from inappropriate or misdirected light fixtures and to discourage the waste of electricity and to improve or maintain nighttime public safety, utility and security.
This article shall be applicable to all outdoor lighting installations, including but not limited to schools, institutions, industrial, commercial and residential properties, applications for site plan and subdivision approval and one- and two-family dwellings. All outdoor light fixtures installed and thereafter maintained in the Township of Chester shall comply with the requirements specified in this article.
A. 
All outdoor lighting fixtures serving residential dwellings shall comply with the requirements specified in this section:
[Amended 7-21-2009 by Ord. No. 2009-10]
(1) 
All outdoor light fixtures serving one- and two-family dwellings and having initial light outputs greater than 1,500 lumens shall be of a type which provides a luminaire that is recessed or enclosed within the fixture so as to eliminate sky glow and glare. Light fixtures with initial light outputs less than 1,500 lumens, such as decorative porch lights, wall sconces, post top lanterns and walkway fixtures, may contain lamps and glass/plastic diffusing devices that extend beyond the opaque fixture enclosure. All outdoor fixtures shall comply with the requirements as specified below:
(a) 
Light distributions generated by light fixtures shall be confined to the property on which they are installed. The maximum vertical illumination, when measured from any point on an adjacent property line at a height of five feet and facing the light fixture(s), shall be no greater than 0.1 vertical footcandles.
(b) 
Outdoor light fixtures properly installed and maintained shall be directed so that there will not be any direct glare source visible from any adjacent residential property.
(c) 
Pole-mounted lighting fixtures shall not exceed 16 feet (base plus pole) in height.
(d) 
Light fixtures installed within any setback area, including front, rear or side yard setbacks, shall contain shielding devices to prevent light spill and glare upward and onto adjacent properties.
(e) 
Accent lighting used to enhance the architectural features, materials color, style of buildings, landscaping, or art shall be located, aimed and shielded so that light is directed only on those features. Such fixtures shall be aimed or shielded to minimize light spill into the dark sky or cause glare or direct light beyond the facade onto a neighboring property or streets.
(2) 
Outdoor recreational and sport facility lighting (see § 113-403).
(3) 
Any developer constructing new residential dwellings in the Township shall provide the owner of the home with a copy of § 113-401A, which addresses residential lighting standards.
(4) 
See § 113-405 for prohibitions.
B. 
All outdoor light fixtures other than those serving residential dwellings shall comply with the requirements specified in this section.
[Amended 7-21-2009 by Ord. No. 2009-10]
(1) 
All lighting shall conform to the standards of the Illuminating Engineering Society Handbook, most recent edition, and the American National Practice for Roadway Lighting (RP-8) approved by the American National Standards Institute (ANSI), most recent edition.
(2) 
Illumination. The average maintained illumination and the average level-to-minimum point ratio of illumination shall conform with the following:

C. 
Where used for security purposes or to illuminate walkways, roadways and parking lots, only outdoor light fixtures having luminaires that are shielded from public view and having the performance characteristics of a cutoff light fixture shall be used.
D. 
Heights. Mounting heights (base plus pole) shall not exceed 16 feet above grade. Lower heights shall be used for walkways.
E. 
Shielding. All luminaires shall be shielded to eliminate glare. Lamps shall be recessed in the luminaire.
F. 
Adjoining properties. The maximum illumination at any point on adjoining properties shall not exceed 0.2 footcandle. The light source shall not be visible from adjacent properties.
G. 
Hours of operation.
[Amended 7-21-2009 by Ord. No. 2009-10]
(1) 
In business, office and/or research and industrial areas, circuits shall be arranged so that at least 50% of all lighting or alternate luminaries shall be turned off after business hours.
(2) 
All outdoor lighting fixtures serving residential dwellings, except those used for security purposes, shall be turned off from 11:00 p.m. until dawn.
H. 
Security lighting. The average maintained illumination for security purposes shall be 0.4 footcandle.
I. 
Special areas. Provisions shall be made for cutoff illumination of loading docks, entrances and other special areas where greater illumination may be required. Each special area shall be on a separate circuit, which shall be turned off when the area is not in use.
J. 
Underground installation. All wires and cables shall be underground.
The lighting plan shall be designed by a lighting design professional, who shall certify that the lighting plan conforms to these standards. The detailed lighting plan shall include:
A. 
Description of outdoor lamp/luminaire combinations, including manufacturer's specifications, such as lamps, optics, angle of cutoff, poles and include manufacturer's catalog cuts.
B. 
Locations and description of every outdoor enclosed light fixture, their aiming angles and mounting heights.
C. 
Foundation details for pole-mounted lights.
D. 
Computer-generated photometric grid showing footcandle readings every 25 feet and the average footcandles.
[Amended 7-21-2009 by Ord. No. 2009-10]
A. 
Outdoor lighting fixtures for purposes of lighting field game areas, courts or swimming pools shall be shielded from public view as observed from outside of the playing field or in the case of residential uses as observed from adjacent residential properties or adjoining public streets. Such light shall have directional and glare control devices, when necessary, to comply with this requirement. The maximum illumination at any point on an adjoining residential property line shall not exceed 0.1 vertical footcandle or 0.2 vertical footcandle on a property zoned for commercial or industrial use.
B. 
Pole-mounted lighting fixtures used to illuminate outdoor recreational activities may exceed 16 feet in height subject to the following regulations:
(1) 
The mounting height of the light fixture shall not exceed 24 feet (base plus pole) in height.
(2) 
All fixtures used for such lighting shall be fully shielded with fifteen-degree cutoff.
(3) 
When the mounting height of the light fixture exceeds 16 feet, a landscaped screen shall be installed along all property lines that are adjacent to the recreational activity for the purpose of screening light glare from adjoining residential uses.
(a) 
The required screen shall be comprised of evergreen and deciduous plant material to form a year-round visual barrier. Evergreen trees shall be a minimum of eight feet high, and deciduous trees shall have a diameter of at least 2.5 inches at time of installation. The quantity of natural screening existing on the property shall be taken into consideration.
(b) 
A landscape plan shall be provided showing the location of each plant and any existing trees that are to be retained as part of the screen. Planting details and a detailed plant list which provides the common and botanical name, quantity of each variety to be installed, size at planting and root condition for all new plants.

A. 
Issuance of building permit. No building permit shall be issued by the Construction Official for any proposed outdoor lighting unless and until a lighting plan as required by this chapter has been reviewed by the Township Engineer and has been found to be in accordance with this chapter.
B. 
Certificate of occupancy. No certificate of occupancy shall be issued by the Construction Official unless and until proof has been submitted to him/her or her that all proposed outdoor lighting has been installed in compliance with an approved lighting plan or, in the case of one- and two-family dwellings, that the outdoor lighting conforms to § 113-401A of this chapter.
C. 
Violations. If the Zoning Official determines that an outdoor light is in excess of the standards established by this article, or that artificial light is emanating from inappropriate or misdirected light fixtures not in compliance with the provisions of this article, the Zoning Official shall give written notice by certified mail to the owner or tenant that the outdoor light(s) be returned to good repair, be made to comply or be removed within 20 calendar days of such notice.
