It shall not be necessary for the local policing authority or the West Rockhill Township Zoning Officer to issue a new notice for each repeated occurrence.
D.
Measurement procedures. The measurement of sound or noise pursuant to this chapter shall be as follows:
(1)
The measurement of sound or noise shall be made with sound level meters Type 1 or Type 2 that meet the standards prescribed by the ANSI. The instruments shall be maintained in calibration and good working order. A calibration shall be made of the system at the time of any noise measurement. Measurements recorded shall be taken so as to provide a proper representation of the noise source. The microphone during measurement shall be positioned so as not to create any unnatural enhancement or diminution of the measured noise. A windscreen for the microphone shall be used when required. A minimum of three sound level readings will be taken. The geometric mean of these readings will be used as the average sound level. If the background noise is equal to the levels set forth in Subsection B of this section above, three dB shall be subtracted out of the average sound level.
(2)
The slow meter response of the sound level meter shall be used to determine that the average amplitude has not exceeded the dBA readings or the limiting noise spectra set forth in Subsection B above.
(3)
Unless otherwise specified, the measurement shall be made at the property boundary on which such noise is generated, or at any point within the receiving property affected by the noise.
(4)
For any source of sound which emits an impulsive sound, the excursions of sound pressure level shall not exceed 20 dBA over the maximum sound level limits set forth Subsection B above, provided that in no case shall they exceed 80 dBA, regardless of time of day or night or receiving land use, using the "fast" meter characteristic of a Type II meter, meeting the American National Standards Institute Specifications Section 1.4- 1971.

§ 450-1808 Lighting.
A.
Findings, purpose and intent.
(1)
Adequate and effective lighting of streets, buildings, parking lots and other facilities is important for comfort, safety and commerce. Wasteful, inefficient or inappropriate lighting, however, is a significant environmental problem. Excessive lighting wastes energy; intrudes upon neighboring properties; is a nuisance to pedestrians, cyclists and motorists on adjacent roadways; disturbs wildlife habitats; impairs human experience of the night sky; and negatively affects the quality of life of our communities.
(2)
Through these regulations, the Township wishes to manage outdoor lighting so that its safety, security and economic benefits are maintained while minimizing dangerous glare, energy waste, light pollution and light trespass.
(3)
The following requirements for outdoor lighting installations promote public safety and welfare during the nighttime while minimizing the adverse effects of glare and light trespass often associated with outdoor lighting. Outdoor lighting should be used only where needed, used only when needed and only that type of lighting which is necessary and proper should be used. This section is intended to implement these principles of good lighting design by regulating the shielding, height, illumination levels and other aspects of outdoor lighting so that Township residents may continue to enjoy the highest quality of life.

(b)
Future amendments to the recommended practices of the Lighting Handbook shall become a part of this section without further action by the Township.
(c)
Where the Lighting Handbook provides for alternatives, this section requires that the safest alternative, as determined by the Township, be used.
(3)
General design requirements. The design calculations for outdoor lighting installations shall be in accordance with the Lighting Handbook. This includes, but is not limited to, technical definitions, terminology, calculation methods and procedures, photometric classifications and photometric testing procedures. Illuminance selection should be based on the usage of the area to be illuminated, the level of activity and nighttime security requirements.
(4)
Illumination levels. Illumination shall have intensities and uniformity ratios in accordance with the current recommended practices of IESNA as contained in the Lighting Handbook.
E.
General regulations.
(1)
All outdoor lighting shall be aimed, located, designed, fitted and maintained so as not to present a hazard to drivers or pedestrians by impairing their ability to safely traverse, (i.e., blinding or disabling glare), and so as not to create a nuisance by projecting or reflecting objectionable light onto a neighboring use or property.
(2)
Floodlights and spotlights, when permitted, shall be installed and/or aimed so that they do not project their output at neighboring residences, adjacent uses, directly skyward or onto a roadway.
(3)
Except as otherwise permitted in this section, all lighting fixtures shall meet IESNA full-cutoff criteria. No lighting shall be permitted that results in glare beyond the boundaries of the property upon which the luminaire is located.
(4)
Except as otherwise permitted in this section or chapter, fixtures meeting IESNA full-cutoff criteria shall not be mounted in excess of 20 feet above finished grade. Fixtures not meeting IESNA "full-cutoff" criteria shall not be mounted in excess of 16 feet above grade.
(5)
Fixtures shall be of a type and design appropriate to the lighting application and aesthetically acceptable to the Township. The use of searchlights, flashing strobe lights and laser lights is prohibited.
(6)
Unless the Township specifically approves all-night lighting (e.g., for safety or security), all outdoor lighting shall be controlled by automatic switching devices, such as time clocks or combination motion detectors and photocells, to permit extinguishing lighting between 11:00 p.m. and 7:00 a.m.
(7)
Where all-night safety or security lighting is to be provided, the lighting intensity levels shall not exceed 25% of the levels normally permitted by this section for the use. All-night safety or security lighting includes the following:
(a)
Lighting essential for the deterrence of break-ins. This type of lighting is limited to exterior door locations.
(b)
Lighting controlled by motion sensors/detectors. This type of lighting is to be used to deter vandalism and theft and shall be placed in locations where the sensors will not be tripped on a reoccurring basis and shall be installed and/or aimed so that they do not project their output at neighboring residences, adjacent uses, directly skyward or onto a roadway.
(c)
Lighting used in conjunction with surveillance cameras. This type of lighting is limited to illuminating automatic teller machines, deposit boxes, building entrances and parking lot/driveway entrances. Fixtures used for this type of lighting shall be designed, fitted and aimed so as not to project their output beyond the objects intended to be illuminated.
(8)
Vegetation screens shall not be employed to serve as the primary means for controlling glare. Rather glare control shall be achieved primarily through the use of such means as cutoff fixtures, shields and baffles and appropriate application of fixture mounting height, wattage, aiming angle and fixture placement.
(9)
Electrical feeds for lighting standards shall be run underground.
(10)
Lighting standards to the rear of the parking spaces shall be placed a minimum of five feet outside paved areas, on concrete pedestals at least 30 inches above the pavement, or suitably protected by other means approved by the Township.

The requirements of this subsection apply to all outdoor lighting installations employed for nighttime area illumination of sports and recreational facilities. All sports and recreational facilities shall be illuminated with the following two systems:
(a)
Performance area lighting. This is the lighting directed upon the field, court, rink, etc., to illuminate the sports/recreational activity taking place upon/within that facility. The maximum permitted post height for the performance area lighting is 60 feet. Post height shall be limited to minimum height necessary to meet the performance area lighting needs of that specific sports/recreational use as determined by the Township.
(b)
General area lighting. This is a low-level lighting system used to facilitate pedestrian circulation, patrons leaving the facility, cleanup, nighttime maintenance, etc. General area lighting shall meet all the requirements for outdoor area and roadway lighting installations listed above in Subsection F.
(2)
Use of full-cutoff luminaires required. All luminaires employed in outdoor sports and recreational lighting installations shall be the full-cutoff luminaire type unless the performance area lighting needs of the sports/recreational use cannot be met through the use of full-cutoff luminaires, as determined by the Township.
(3)
Use of glare shields required for noncutoff luminaires types. Where noncutoff luminaires, such as floodlights, must be used to meet the lighting design objectives for the performance area lighting, the luminaires shall be equipped with glare shields, visors, barn doors, and other similar shielding accessories as required to meet the following criteria:
(4)
Maximum maintained illuminance levels. The maximum maintained illuminance levels permitted at the property line(s) during the nighttime, produced by the sum of all outdoor sports and recreation lighting installations on a lot shall meet the requirements of Table 18-4.
(5)
Design submittal and approval requirements. The design for all outdoor sports and recreation lighting installations shall be submitted for review and approval by the Township. The submission shall include a visual-impact plan that demonstrates appropriate steps have been taken to prevent or mitigate glare on-site, off-site, as viewed by drivers on adjacent streets, and so as to retain the intended character of the general vicinity of the site. This submission may also require the inclusion of initial vertical footcandle values at specific off-site venues, e.g., bedroom windows of adjacent residential uses.
(6)
All outdoor sports and recreation lighting shall be extinguished between 9:00 p.m. and 7:00 a.m. on Sunday through Thursday nights and between 11:00 p.m. and 9:00 a.m. on Friday and Saturday nights and nights preceding federal holidays. In addition, the performance area lighting shall be turned off no more than 30 minutes after the end of the event or use of the sports/recreational facility.
(7)
Regulation-size golf courses (Use C7) and firearm shooting facilities (Use C16) shall not be artificially lit and shall not be permitted to operate in the Township during the nighttime hours.
H.
Requirements for outdoor sign lighting, outdoor lighting of facades of buildings and structures and outdoor landscape lighting.
(1)
Applicability of requirements. The requirements of this subsection apply to all outdoor lighting installations employed for the nighttime illumination of signs, billboards, the facades of buildings and structures, fountains, trees, shrubs, vegetation and the like.
(2)
Use of full-cutoff luminaires required. All luminaires employed in outdoor lighting of signs, facades and landscape shall be of the full-cutoff luminaire type, unless the lighting needs of the signs, facades or landscaping cannot be met through the use of full-cutoff luminaires, as determined by the Township.
(3)
Use of glare shields required for noncutoff luminaire types. Where noncutoff luminaires, such as floodlights, are used to meet the lighting design objectives for outdoor sign, billboard, facade and/or landscape lighting, the luminaires shall be equipped with glare shields, visors, barn doors and other similar shielding accessories as required to ensure that the candlepower distribution from all lighting installations shall be cut off at all angles beyond those required to restrict direct illumination to within the perimeter of the sign or billboard being illuminated.
(4)
Externally illuminated signs, billboards and facades shall be lighted by fixtures mounted at the top of the sign and aimed downward.
(5)
Fixtures used for architectural lighting, e.g., facade, fountain, feature and landscape lighting shall be designed, fitted and aimed so as not to project their output beyond the objects intended to be illuminated.
(6)
All outdoor lighting falling under the requirements of this subsection shall be extinguished between 11:00 p.m. and 7:00 a.m. This restriction does not apply to nonresidential uses that are open between the hours of 11:00 p.m. and 7:00 a.m., in which case the lighting must be extinguished when the nonresidential use is closed.
I.
Requirements for residential and farm outdoor lighting.
(1)
Applicability of requirements. The requirements of this subsection apply to all outdoor lighting installations located on residential lots developed with a single-family dwelling, a two-family dwelling, or a farm. Luminaries with an aggregate rated output of a standard forty-watt incandescent lamp (i.e., 500 lumens), are exempt from the requirement of this subsection.
(2)
Use of glare shields required for noncutoff luminaire types. All noncutoff luminaires, such as floodlights, shall be equipped with glare shields, visors, barn doors, and other similar shielding accessories as required to meet the following criteria:
(a)
For area lighting applications, the candlepower distribution from all luminaires shall be cutoff at and above the horizontal (level).
(b)
For all other applications, the candlepower distribution from all luminaires shall be cut off at all angles beyond those required to restrict direct illumination to within the area or surface being illuminated.
J.
Temporary outdoor lighting.
(1)
Applicability of requirements. The requirements of this subsection apply to all outdoor lighting installations which are employed on a temporary basis not exceeding 30 days in duration. Temporary lighting installations include, but are not limited to, seasonal or holiday displays, carnivals, community fairs, traveling circuses, sales/promotional displays and the like.
(2)
Use of glare shields required for noncutoff luminaire types. All noncutoff luminaires, such as floodlights, shall be equipped with glare shields, visors, barn doors and other similar shielding accessories as required to meeting the following criteria:
(a)
The candlepower distribution from all lighting installations shall be cut off at all angles beyond those required to restrict direct illumination to within the perimeter of the area, surface, object or feature being illuminated.
K.
Maximum permitted illumination.
(1)
Total outdoor light output for all uses other than B1 Single-Family Detached Dwellings or A1 Farming/Agriculture shall not exceed the lumens/acre set forth in Table 18-5. The values in this table are the upper limits. Property owner shall only install those fixtures necessary to meet the minimum outdoor lighting needs of the use. Performance area lighting systems discussed under outdoor sports and recreational lighting are excluded from this lumen/acre cap requirement.
(2)
Table 18-5. Sites/properties improved with only full-cutoff and/or cutoff fixtures shall comply with the first row of the following Table. Sites/properties improved with only noncutoff fixtures shall comply with the second row of the following Table. Where there are both cutoff (full-cutoff and cutoff) and noncutoff fixtures on a property, the maximum allowed lumens per acre shall be calculated twice, once for the total of all fixtures and once including only the noncutoff fixtures. In such a case, the maximum lumens per acre must meet both requirements.
