A.
Intent. The intent of this § 200-10 is to regulate the use of outdoor illumination. Where safety and security concerns warrant it, outdoor illumination is required to be installed, operated, and maintained. For commercial, industrial, multifamily residential, recreational, institutional, and public uses, outdoor illumination is required for all off-street parking and loading areas and for all driveways providing access. All outdoor illumination shall avoid producing glare.
B.
Illumination levels. All outdoor illumination shall have intensities and uniformity ratios consistent with the standards in the current edition of the Lighting Handbook and/or Recommended Practices of the Illuminating Engineering Society of North America (ISENA). "Illumination levels" shall be defined as maintained horizontal footcandles on the task, and average illumination values shall not exceed minimum values by more than the product of the minimum value and the specified ISENA uniformity ratio for the activity in question.
C.
Control of glare. Glare control shall be achieved primarily through the use of such means as fixture cutoffs, shields, and baffles and appropriate application of fixture mounting height, wattage, aiming angle, and fixture placement. Outdoor illumination shall be installed so that the glare or reflection visible from a street or residence adjacent to the property being illuminated shall not be greater than 0.1 footcandle at the property or boundary line, except where the adjacent property is in nonresidential use, in which case the standard shall be 0.2 footcandle.
D.
Fixture design. Except as otherwise permitted for recreational and sports lighting, below, all outdoor illumination fixtures, including mounting base, shall not exceed 16 feet in height above the finished grade of the surface being illuminated. All fixtures shall be of a type and design appropriate to the outdoor illumination application, as follows:
(1)
For lighting predominantly horizontal task surfaces, such as, but not limited to, roadways, areas of pedestrian and vehicular passage, merchandising and storage areas, automotive fuel dispensing facilities, automotive sales areas, loading docks, active and passive sports and recreational areas, building entrances, sidewalks, paths, site entrances and parking areas, fixtures shall be aimed straight down and meet IESNA full cutoff criteria.
(2)
For decorative outdoor illumination and the lighting of predominantly nonhorizontal tasks, such as, but not limited to, facades, landscaping, signs, fountains, displays, flags and statuary, the use of floodlighting, spotlighting, wall-mounted fixtures, decorative globes and other fixtures not meeting IESNA full cutoff criteria, fixtures shall be selected and installed so that only the nonhorizontal task is directly illuminated and shall be equipped with or be capable of being equipped with devices such as shields, visors or hoods when necessary to redirect offending light distribution.
(3)
The height of the outdoor illumination poles for recreational and sports lighting shall be dictated by that setup which best satisfies the lighting illumination levels specified by IESNA standards and recommended practices and also controls glare visible from adjacent properties or streets.
E.
Hours of illumination for floodlighting or high-intensity outdoor illumination. All outdoor illumination, including surveillance, security, or safety outdoor illumination, shall conform to the standards of Subsection C, Control of glare, at all hours.
F.
Recreational and sports lighting. Except as otherwise permitted for recreational and sports lighting in Subsection G, below, all outdoor illumination fixtures, including mounting base, shall not exceed 35 feet in height above the finished grade of the surface being illuminated. Outdoor illumination for active recreational facilities shall be permitted only by conditional use. In determining the appropriateness of proposed outdoor illumination for active recreational facilities, the Board of Supervisors shall apply the general criteria and standards for conditional uses of Articles XVII and XVIII and shall approve an application for outdoor illumination for active recreational facilities only in cases when the Board is able to ascertain that the proposed outdoor illumination will:
(1)
Represent appropriate application of fixture mounting heights, wattage, aiming angle, and fixture placement.
(2)
Control glare through the use of cutoff fixtures, shield, and baffles.
(3)
Not represent a hazard to drivers or pedestrians by impairing their ability to safely traverse streets, driveways, sidewalks, pathways, and trails.
(4)
Not project output skyward.
(5)
Not be used after 10:00 p.m. Sundays through Thursdays and 11:00 p.m. Fridays and Saturdays.
G.
Recreational and sports lighting in Institutional Districts. Outdoor illumination for active recreational and sports facilities accessory to public, private, and parochial secondary schools, universities, and colleges shall be permitted in Institutional Districts subject to the following conditions:
(1)
The height of poles or structures supporting recreational and sports lighting fixtures permitted shall not exceed 90 feet, which shall be measured from the mounting base of the pole or support structure at grade to the highest point of the pole or structure. If the pole or support structure is on a sloped grade, then the average between the highest and lowest grades shall be used in calculating the height.
(2)
Lighting shall be accomplished using the most advanced available fixture technology and design techniques appropriate for the use that minimize off-site glare and light trespass to the maximum extent possible. Light fixtures shall not project skyward and shall control glare at the property line through the use of cutoff fixtures, shields, and baffles. Fixtures shall not present a hazard to drivers or pedestrians by impairing their ability to safely traverse streets, driveways, sidewalks, pathways, and trails and shall be mounted at an appropriate height, angle, and location to comply with the above conditions.
(3)
Lights may only be illuminated in conjunction with one of the following events:
(a)
A school-sponsored recreational or athletic sporting event, such as a football, soccer, field hockey, or lacrosse game, or marching band cavalcade where some of the participants are enrolled at the school, university, or college where the lights are located (an "event");
(b)
A field practice for such events; or
(c)
A playoff or championship game.
(4)
Lights may not be used for more than two consecutive nights in any one calendar week.
(5)
Lights shall not be illuminated on Sundays and must be extinguished no later than 10:00 p.m. on Monday through Thursday and by 11:00 p.m. on Fridays and Saturdays.
(6)
Lights may be illuminated for a total of only 40 events at the school property during one school year (August 15 of a given year through June 15 of the following year) as defined in Subsection G(3) above. For example, if a middle school and high school are located on one unified parcel of property, lights may only be illuminated for a total of 40 events at such unified parcel, regardless of the number of fields that are located on such parcel. For purposes of this subsection, the term "event" shall not include field practices or playoff/championship games. For example, a championship football game sponsored by the PIAA shall not constitute an event and shall not be counted in the total number of allowable events per school year as regulated in this subsection. At the end of each school year, the school, university, or college shall submit an annual report of the dates and hours of the events where the lights were illuminated to prove compliance with this restriction;
(7)
All light posts must be set back at least 50 feet from the property line.
(8)
As part of a permit application to provide recreation/sporting event lighting, the school, university, college, or applicant proposing to use outdoor lighting as permitted herein shall submit a lighting plan to the Township Engineer for review in conformity with all applicable sections of this chapter. In addition, the Township Engineer may determine the necessity of a review of all plans and applications by a lighting consultant to confirm that the proposed fixtures comply with the conditions of this chapter.
H.
Temporary outdoor illumination. Temporary floodlighting and spotlighting for such uses as, but not limited to, public festivals, celebrations, sporting and recreation events is permitted, subject to the following conditions:
(2)
Illumination shall conform to the standards of Subsection E, Hours of illumination for floodlighting or high-intensity outdoor illumination.
(3)
Permits issued by the Township for temporary illumination shall be valid for up to seven consecutive days and shall be issued no more than three times for a parcel of land in any calendar year.
