17.24.020 Parking Lot Standards

A. All luminaires shall be cut-off luminaires as defined by the IESNA Handbook, page 7-8, except as follows:

1. If the design is of a period or architectural style, as determined by the Director of Community and Economic Development, within the overall design of the project, alternatives or supplements to the lighting may be used provided that:

a. If such are not “cut-off” luminaires as defined by IESNA, the maximum initial lumens generated by each fixture shall not exceed two thousand (2,000).

b. Mounting heights of such alternative luminaires shall not exceed fifteen (15) feet above grade.

c. All luminaires of a period or architectural style shall be approved by the Director of Community and Economic Development.

B. Parking areas adjacent to residential lots shall have approved glare shields to prevent glare as approved by the CPTED Section.

C. Illuminance, mounting height, and uniformity ratio shall conform to the requirements in Table 17.24.020.

Table 17.24.020 Parking Lot Lighting Standards
	District 1	District 2	District 3	District 4
Mounting Height (Maximum)	25 ft	16 ft	25 ft	25 ft
Minimum Illumination Level*	No less than .5 fc	No less than .5 fc	No less than .2 fc	No less than .2 fc
Maximum Illumination Level**	No more than 7.5 fc	No more than 7.5 fc	No more than 3 fc	No more than 3 fc
Uniformity Ratio***	15:1	15:1	15:1	15:1

* Minimum Illumination Level (in footcandles “fc”) at the darkest spot on the parking area surface.

** Maximum Illumination Level (in footcandles “fc”) at the brightest spot on the parking area surface.

*** Minimum Uniformity Ratio is no less than 15:1. Measured here for maximum light level compared to minimum light level.
