The cumulative EIR LOS analysis for this <br /> intersection included adjustments to signal timing to <br /> account for the nearby CalTrain railroad crossing. <br /> Calculations conducted for the intersection under <br /> Cumulative (2020)With Project conditions without <br /> adjusted signal timings (i.e., if the train did not affect <br /> the operations at the intersection)indicate that the <br /> intersection would operate acceptably during the AM <br /> and PM peak hours. Therefore, if the railroad tracks <br /> were to be grade-separated from Whipple Avenue, <br /> the intersection is expected to operate acceptably. <br /> However, due to the limited distance between the <br /> intersection and the CalTrain railroad tracks, grade <br /> separation may not be feasible. <br /> (2) Widening of the Eastbound Intersection a <br /> Approach to Achieve Acceptable LOS During Both in <br /> � CD <br /> -0 ). <br /> S = Significant a m _ <br /> LS = Less than significant a <br /> SU = Significant unavoidable impact <br /> NA = Not applicable <br /> T:110695 Pete's Harbor EIR Addendumlrevised addendum no 21Table 1-1(10695-01).doc <br />
