7.1.A. - Page 50 <br /> Photometric Analysis — <br /> The following photometric analysis was conducted to simulate three very typical lighting situations to <br /> provide The City assurance that the LED fixtures presented in this proposal have superior performance. <br /> Assumptions for the three cases that were modeled below are as follows <br /> - All values calculated using RP -8, R3 asphalt, Caltrans type 15 architecture (31.5' mounting <br /> height, 6' arm) <br /> - 70W HPS equivalent —Two lane road, staggered fixture placement, no turn lane, 12' lane widths, <br /> 6' side walk. I have assumed local road, medium pedestrian conflict. This is a very standard <br /> case for many residential streets. <br /> o IES recommendations - 0.7fc average, 6:1 avg /min <br /> o Max spacing with this arrangement — 211' between poles <br /> - 100W HPS equivalent — Two lane road, fixtures on one side of street, single turn lane, 12' lane <br /> widths, 6' side walk. I have assumed a local road, medium pedestrian conflict. This is a fairly <br /> standard case for some of the light industrial and commercial areas. <br /> o IES recommendations — 0.7fc average, 6:1 avg /min <br /> o Max spacing with this arrangement — 62' between poles <br /> - 200W HPS equivalent — Four lane road, fixtures mounted on median, 12' lane widths, 6' side <br /> walk. I have assumed a major road, high pedestrian conflict. This is very similar to the condition <br /> of Veteran's Blvd. <br /> o IES recommendations — 1.7fc average, 6:1 avg /min <br /> o Max spacing for with this arrangement — 93' between poles <br /> These cases do not represent 100% of the fixtures in Redwood City. For each phase of retrofit, as part of <br /> the audit, the existing fixture location and position will be considered with the average lighting levels <br /> and pedestrian, per IES recommendation in RP -8, by the factory representative. <br />
