A. 
Street Lights. Street lights shall meet the following requirements:
1. 
Streetside lighting shall consist of 16-foot-high, round tapered pole with decorative base and luminaire, in accordance with the University Place Standard Notes and Details.

Median lighting shall consist of 35-foot-high, round tapered pole with decorative base, luminaire, and decorative mast arms in accordance with the University Place Standard Notes and Details.
3. 
Poles shall be positioned to provide a minimum 24-inch clearance between the edge of the pole base and the vertical face of the curb.
B. 
Spacing. Spacing will be determined using the following criteria:
Average Maintained Horizontal Illumination (Foot-Candles)
Road Class
 
Neighborhood Collector Arterial
0.6
Collector Arterial
0.6
Secondary Arterial
0.8
Major Arterial
0.8
Uniformity Ratio:
6:1 average: minimum for local
 
4:1 average: minimum for collector
 
3:1 average: minimum for secondary and major arterial
Dirt Factor = 0.85, lamp lumen depreciation factor – 0.073
Minimum Weak Point Light = 0.2 fc except residential local street
Average Illumination at Intersections = 1.5 times the illumination required on the more highly illuminated street
