No <br />mitigation measures are required. <br />d) Create a new source of substantial light or glare, which would adversely affect day or nighttime <br />views in the area? <br />Less Than Significant With Mitigation Incorporated. The immediate area surrounding the replacement <br />project sites are characterized by residential development. Existing lighting sources include streetlights and <br />interior building lights in residential setting. <br />The 6u Street Site and the Raitt Street Site would include nighttime lighting for the skate area and rest of the <br />park area. Figure 11, Nighttime Light Poles, shows the type of nighttime lighting to be installed at the parks. The <br />light poles are anticipated to be 14 feet tall LED fixtures from Leotek Electronics that conserves energy and <br />focused to minimize light overflow into the night sky or adjacent properties. Figure 12, 6th Street Site Photometric <br />Plan 1, illustrates projected foot-candle (fc) levels at ground level at approximately 10-foot intefval from the <br />light fixtures at the 6" Street Site. Foot-candle is the unit of measure expressing the quantity of light on a <br />surface. One foot-candle is the illuminance produced by a candle on a surface of one square foot from a <br />distance of one foot. The general benchmarks for light levels are shown in Table 1. As shown in Figure 12, <br />there would be a total of five light poles on the 6u Street Site, acid the light levels would range from 24 fc to <br />0.5 fc. <br />Table 1 General Light Levels Benchmark <br />Outdoor Light <br />Foots ndles <br />Direct Sunlight <br />10,000 <br />Full Daylight <br />1,000 <br />Overcast Day <br />100 <br />Dusk <br />10 <br />Twilight <br />1 <br />Deep Twilight <br />0.1 <br />Full Moon <br />0.01 <br />Quarter Moon <br />0.001 <br />Moonless Night <br />0.0001 <br />Overcast Night <br />0.00001 <br />Gas station canopies <br />25-30 <br />Typical neighborhood streetlight <br />1.0-5.0 <br />Source: NOAO 2016. <br />75C-63 <br />
