A. Outdoor Recreational Facilities: Lighting for outdoor recreational facilities that are accessory to community service uses, colleges and university uses, educational facility uses, parks and open space uses, and religious/private group assembly uses may be exempted from the minimum standards or exceed the maximum standards of this article; provided, that the following specific approval criteria are met. To apply for this exemption, a lighting plan must be submitted to the city and must be certified as conforming to the standards listed below by a registered engineer with lighting certified (LC) status according to the national council on qualifications for the lighting professions (NCQLP).
1. The facility must satisfy the requirements set forth in the most current editions of the Illuminating Engineering Society of North America (IESNA) RP-6 recommended practice for sports and recreational area lighting and the IESNA lighting handbook. Appropriate lighting criteria must be selected based on the class of play of the facility and participants as defined by the IESNA.
2. Fixtures must be located, aimed and shielded to the extent possible to prevent light trespass and glare onto adjacent properties according to the following standards:
a. Luminaires must be aimed no greater than a distance two (2) mounting heights or less from the base of the pole (a maximum angle of 63 degrees up from nadir or a minimum of 27 degrees down from horizontal).
b. Fixtures must be mounted so as to meet the criteria of a "cutoff fixture" as defined in chapter 9, article D, "Outdoor Lighting Definitions", of this title.
c. Illumination must not exceed 0.5 initial horizontal foot- candles and 2.0 initial maximum foot-candles as measured at any point along a property boundary that is adjacent to or across the street from properties that are zoned residential.
3. Laser lights, searchlights, and mercury vapor bulbs are prohibited.
4. Use of such lighting is restricted to those hours when the recreational facility is in use. Lighting for recreational facilities must be turned off by one hour after conclusion of the recreational activity. For facilities located in or adjacent to residential zones, the curfew for recreational facility lighting is eleven o'clock (11:00) P.M. Illumination of such facilities shall be permitted after eleven o'clock (11:00) P.M. only to conclude a scheduled event that was unable to conclude before the curfew due to unusual circumstances.
B. Outdoor Display Lots: Lighting for outdoor display lots that are accessory to outdoor storage and display oriented uses may exceed the total outdoor light output standards specified in section 14-5G-5 of this article; provided, that the following specific approval criteria are met. To apply for this exemption, a lighting plan must be submitted to the city and must be certified as conforming to the standards listed below by a registered engineer with LC status according to the NCQLP.
1. The display lot must be designed to achieve no greater than the minimal illuminance levels for the activity as recommended by the Illuminating Engineering Society of North America (IESNA).
2. Display lot lighting that exceeds the total outdoor light output standards specified in section 14-5G-5 of this article must be turned off at eleven o'clock (11:00) P.M. or within thirty (30) minutes after close of business, whichever is later. After this time, lighting on the property must comply with the total outdoor light output standards specified in section 14-5G-5 of this article.
3. All other standards and requirements of this article must be met.
C. Other Lighting On Properties Containing Special Uses: All lighting not directly associated with the special use areas listed in subsections A and B of this section must conform to the lighting standards contained in this article. If recreational facilities or outdoor display lots take advantage of the exemptions allowed in this section, the net acreage for the determination of compliance with the total outdoor light output standards for other lighting on the property must not include the area of the recreational facility or outdoor display lot.
