feet MSL). The flight corridors are incorporated into the City's General .flan. <br />The. Project does not conflict with the flight corridors. <br />(d) Approximately 8.3 .acres, or l S. 4 per cent of the Project site, is located <br />within the Inner Turning. Zone (safety zone 3). within this area, the 4-story, <br />140,000 square foot office building would cover approximately .83 acre of ground <br />area. The remaining portion of the Project site within safety zone .3 would be <br />devoted to paring and landscaping. The probability of any one -acre site located <br />in safety zone 3 being the site of an .accident is .11 per cent, or 1 in 90.9. In other <br />words, out of 909 aircraft accidents, only one would have the potential of . <br />affecting any one specific one -acre location within safety zone 3, including the <br />office building to be located in the Project site. This is not a statistically <br />signif cant probability, in light of the accident rate of 1 -3 accidents per year; on <br />average. <br />(e) Traffic Pattern Zone (safety zone 6..) incorporates the remaining .36.7 :acres <br />(81.6 %) of the Project site, including the 7, 8 and 10 -story office buildings. Only <br />3.44 acres of the portion of the Project .site .located .in the Traffic Pattern Zone is <br />covered by occupied structures. The potential for an accident involving any <br />portion of the site with an occupied structure is on the order of 0.07 per cent, or <br />one accident out of 1,429 accidents. This :does .not represent a statistically <br />signif cant accident potential, in light of the accident rate of 1 -3 accidents per year, <br />on average. <br />M Because the traffic pattern :at San Carlos Airport is only on one side, it <br />could be .argued that these accident rates should double. Even if this argument is <br />accepted, the potential for accidents affecting the site would still be extremely <br />love. <br />(g) The Traffic Pattern done includes the 10 -story building. within this zone, <br />the 1993 Airport Ladd Use .Pl . .... ook states that the potential for <br />aircra accidents is relatively low and the need for land use restrictions is thus <br />minimal. Only very large assemblies of people -- 150 people or more per gross <br />acre -- are recommended to be avoided. At a. max n urn average density of about <br />94 people per gross acre, the density of the Project is well Within the criteria <br />established in the Handbook for this zone. <br />(h) Because safety area land use density restrictions are more effective when <br />a lied at a general plan or large development level, measurement on a gross acre <br />pp g <br />basis is most appropriate. On this basis, the 4,000 people expected to occupy the <br />45 -acre site under maximum- occupancy conditions results in .an average density <br />figure of 89 people per gross acre. This is well within the density criteria <br />established in the Handbook. <br />-2600 <br />F'NDNGi LD0C <br />5130196 1 0:51 AM <br />
