A. Lighting Standards In All Districts Except Those Containing Single-Family And Two-Family Dwellings:
1. Wall or roof lighting may be used to illuminate the pedestrian walkways, entrance areas, and yard areas within thirty feet (30') of the building. No wall or roof lighting shall be used to illuminate areas for motor vehicle parking or access unless the zoning officer finds the following:
a. That the proposed lighting is not in conflict with the stated purpose in this chapter;
b. That the proposed lighting will not unreasonably harm or restrict public health, safety, and welfare or create a nuisance; and
c. The proposed luminaire has a cutoff angle of less than or equal to sixty six degrees (66°).
2. Any open area used for motor vehicle parking, storage, or access shall be illuminated with freestanding luminaries. Freestanding luminaries are permitted to be a maximum of thirty feet (30') in height with a three foot (3') support, for a maximum height from the ground of thirty three feet (33'). When a luminaire is located within five hundred feet (500') of a protected residential property, the maximum permitted luminaire height shall be twenty five feet (25'). All measurements shall be taken from the average elevation of the finished grade within ten feet (10') of the structure or fixture to the highest point of the luminaire. All luminaries must have a total cutoff angle equal to or less than ninety degrees (90°). The use of exterior lighting with a cutoff angle greater than ninety degrees (90°) shall be permitted only when the zoning officer finds the following:
a. That the lighting is not in conflict with the stated purpose in this chapter;
b. That the proposed lighting will not unreasonably harm or restrict public health, safety, and welfare or create a nuisance; and
c. The proposed lighting will not result in an impairment of vision creating a hazard for vehicular or pedestrian traffic.
3. In no instance shall low pressure sodium fixtures be used to illuminate unprotected residential property unless the zoning officer finds the following:
a. That the proposed lighting is not in conflict with the stated purpose in this chapter;
b. That the proposed lighting will not unreasonably harm or restrict public health, safety, and welfare or create a nuisance; and
c. The color distortion effect of low pressure sodium lighting will not create a hindrance to crime prevention and investigation.
B. Intensity Of Lighting In All Districts Except Those Containing Single-Family And Two-Family Dwellings:
1. The amount of illumination attributable to exterior lighting from a property shall not exceed one foot-candle when measured at any boundary line with an adjoining property. This provision may be waived by the issuing authority when:
a. The proposed lighting is not in conflict with the stated purpose of this chapter;
b. The proposed lighting will not unreasonably harm or restrict public health, safety, and welfare or create a nuisance; and
c. The proposed lighting will not result in an impairment of vision creating a hazard for vehicular or pedestrian traffic.
2. All parking lot and parking structure lighting located within three hundred feet (300') of a protected residential property line may be illuminated not more than one hour before the start of business and shall be extinguished within one hour after the end of business, except as approved by the zoning officer after finding the following:
a. The property has been identified as an area where the incidence or potential for crime warrants additional lighting;
b. Additional lighting is required to increase visibility of a property which is not readily accessible for police during routine patrol; and
c. The use of timers, sensors, or other devices that produce a reduced lighting level that does not conflict with the stated purpose in this chapter.
C. Glare/Illumination: In all zoning districts, any lighting shall be arranged to reflect the light away from adjoining property. A person shall not conduct a use that has a source of illumination that produces glare clearly visible beyond a property line or creates a sensation of brightness within a visual field so as to cause annoyance, discomfort, or impairment of vision. Lenses, deflectors, shields, louvers, or prismatic control devices shall be used to eliminate nuisance and hazardous lighting to facilitate compliance with this requirement.
D. Parking Structures: Luminaries used for illumination of designated pedestrian walkways in parking structures shall be of a significantly different color value than luminaries used for illuminating vehicle parking and drive aisles. (Ord. 1301, 3-15-2004)
