(A) Illumination levels shall be measured with a photoelectric photometer having a spectral response similar to that of the human eye, following the standard spectral luminous efficiency curve adopted by the International Commission on Illumination.
(B) All outdoor lighting shall comply with the following standards.
(1) All illumination structures, except for approved street lights, shall be shaded, shielded or directed to prevent direct light from being cast upon any adjacent property or public right-of-way and to prevent glare or other objectionable problems to surrounding areas.
(2) No light fixture shall have any blinking, flashing or fluttering lights or other illuminating device which has a changing light intensity, brightness or color, nor shall any beacon or spot lights be permitted.
(3) Neither the direct, nor reflected light from any light fixture shall create a disabling glare causing traffic hazards to motor vehicle operators on public roadways.
(4) Any non-residential off-street parking or loading area in use at night shall contain a system of lighting to provide an adequate standard of at least one foot-candle of illumination over the area of the parking area to be used.
(5) Lighting shall be designed so as not to create more than one foot-candle of illumination at any residentially zoned property boundary, or more than five foot-candles at any commercially zoned property boundary.
(6) Light fixtures used to illuminate objects mounted on a pole, platform or pedestal shall not use a spotlight that will extend beyond the illuminated object. Uplighting of these structures shall cease after 11:00 p.m., except for uplighting of the American flag, or unless otherwise regulated.
(7) All parking area lighting shall be located within a landscaped area or island.
(8) (a) All exposed portion of pedestals or platforms on which parking lighting may be mounted shall be designed with an approved decorative material or finish so as to eliminate exposed concrete finish appearance. All other outdoor light fixtures lawfully installed prior to and operable on the effective date of this chapter are exempt from all requirements unless:
1. Existing outdoor lighting fixtures are replaced, removed or reinstalled; or
2. Existing outdoor lighting systems are judged to be a nuisance due to excessive, objectionable light emission as assessed by the Director; or if the emissions cause unsafe or hazardous conditions. Upon notice by the Director, the owner of such lighting system will have 30 days to comply with the provisions as set forth in this section. A 30-day extension may be granted by the Director.
(b) The Director may require a special inspection to ascertain compliance with this ordinance.
