A. Mounting heights for lighting fixtures and illumination standards for open-air parking lots are set forth in RZC 21.34.120, Mounting and Illumination Standards Table, of this chapter.

B. Open-air parking lot lighting shall be designed to provide:

1. Adequate vision, comfort, and safety.

2. Uniform lighting throughout the facility with no dark patches or pockets.

3. A minimum value of lighting necessary for the safety and identification of features.

C. Open-air parking lot lighting shall not cause direct illumination on adjacent and nearby properties or streets. Fixtures should be of a type or adequately shielded so as to prevent glare from normal viewing angles.

D. All lighting fixtures serving open-air parking lots, except as allowed in subsection RMZ 21.34.050.E of this section, shall be full cutoff fixtures as defined by the Illuminating Engineering Society of North America (IESNA).

E. If the design of an area suggests the use of a particular “period” or architectural style fixture, the Technical Committee may permit alternatives or supplements to the lighting described above.

F. During periods of nonuse, the lighting of parking facilities with Basic Security lighting should be turned off or reduced to conserve energy.

G. The Technical Committee may allow increases from Basic to Enhanced Security lighting levels (RZC 21.34.120, Mounting and Illumination Standards Table, of this chapter), when personal security is an issue, such as where the parking facility is used during all hours of the day and night, where special security needs exist, or where vandalism or crime is possible. The Technical Committee may consider specific site characteristics, level of vehicle and pedestrian conflict, special security needs, and history or likelihood of crimes in making its determination.
