(a) A lighting plan is required for all uses that are required to file a development plan and shall be approved according to the procedures set forth in Chapter 1111. All existing uses on which exterior lighting is installed or changed shall conform to these standards. The lighting plan shall demonstrate compliance with the exterior lighting standards of this Section, and shall include the following items:
(1) A site plan showing location of all exterior light fixtures, controllers and transformers.
(2) Property boundaries, building location(s), parking lot layout, pedestrian paths, adjacent rights-of-way, north arrow and scale.
(3) Specifications and drawings or photographs for all exterior light fixture types, poles, conduit and appurtenant construction.
(4) Lamp wattage of all proposed luminaries.
(5) Information that indicates a minimum light level of one-half (0.5) foot candles at grade in all vehicular use areas and connecting pedestrian paths.
(6) Cut sheets for all proposed exterior light fixtures and poles.
(7) Any other information and data reasonably necessary to evaluate the required lighting plan.
(b) General Requirements.
(1) All outdoor lighting fixtures regulated according to this Section, including but not limited to those used for parking areas, buildings, building overhangs, canopies, signs, displays and landscaping, shall be full-cutoff type fixtures.
A. Full-cutoff fixtures shall be installed and maintained so that the shielding is effective as shown in Figure 2 below.

B. Automobile-oriented uses such as gasoline stations, service stations and drive-through facilities shall install recessed ceiling fixtures in any canopy.
C. Signs that are wholly illuminated from within and freestanding signs that are externally illuminated with an exposed incandescent lamp not exceeding twenty-five (25) watts shall not require shielding.
(2) Light trespass over a property line shall be limited to no more than one quarter (0.25) horizontal foot-candle at the property line. All on-site lighting of buildings, lawns, parking areas and signs shall be designed so as not to shine onto any adjacent residential property or building, or to cause glare onto any public street or vehicle thereon.
(3) Measurement.
A. Light levels shall be measured in foot-candles with a direct reading, portable light meter. Readings shall be taken only after the cell has been exposed long enough to take a constant reading.
B. Measurements shall be taken at the property line, along a horizontal plane at a height of three-and-one-half (3.5) feet above the ground.
(4) All non-essential outdoor lighting fixtures, including parking, sign, display and aesthetic lighting, shall be turned off after business hours. Only that lighting needed for safety or security may remain lit after close of business, in which case the lighting shall be reduced to the minimum level necessary.
(5) Maximum Height of Light Poles. The total height of exterior lighting poles shall not exceed the following height regulations. Height shall be measured from the average grade surrounding each light pole:
Districts:
Maximum Height:
R-1, R-2
20 feet
M-1, M-2, B-1
25 feet
B-2, B-3, E, I
28 feet
(c) Exemptions.
(1) Decorative outdoor lighting fixtures with bulbs of less than twenty-five (25) watts, installed seasonally, are exempt from the requirements of this Chapter.
(2) Temporary construction or emergency lighting is exempt from the requirements of this Section. Such lighting shall be discontinued immediately upon completion of the construction work or abatement of the emergency necessitating such lighting.
(3) All outdoor lighting fixtures existing and legally installed prior to May 25, 2006 shall be exempt from the requirements of this Section. When existing lighting fixtures become inoperative, their replacements shall be subject to the provisions of this Section.
(4) Nothing in this Section shall apply to lighting required by the FAA or any other federal regulatory authority.
