Queueing: As described previously, construction of the Modified Project includes changes to the N. Main Street at Walkie Way intersection to provide a left turn into the Project site and changes to the median to provide adequate storage length. Table T-11 provides the queueing in the year 2040 plus Modified Project condition. As shown, all queues are forecast to fit within the storage length, except for the southbound left turn at Main Street and Edgewood Road in the p.m. peak hour with the existing median. An exceedance of the storage length by 11-feet is forecast to occur in the p.m. peak hour without the Modified Project. With Modified Project, the exceedance would increase by 3 feet in year 2040 conditions. As detailed in Section 2, Modifications to the Original Project, the median would be modified to accommodate these queues. Thus, operation of the Modified Project would result in a less than significant impact related to queuing. In addition, this operational condition is improved in comparison to the conditions that would occur from implementation of the Original Project Option A, which included one driveway to the Project site that was sited along N. Main Street, and resulted in a p.m. peak hour queue of 235 feet (71 feet greater than the queue of 164 feet shown in Table T-11). Therefore, no new or greater impacts related to queuing would occur from implementation of the Modified Project.

Attachment B. Bold = Exceeds storage length 1Queues reported are 95th Percentile queue lengths per movement in feet. EBL = eastbound left; EBTL= eastbound through-left turn; NBL = northbound left; NWR = northwest bound right; SBL = southbound left; SBT= southbound turn; SBT2 = southbound second turn; SER = southeast bound right turn; WBTL = westbound though-left turn Freeway Segments: As shown in Table T-12, both with and without the Modified Project in Year 2040 condition, all traffic study area freeway facilities would operate at unsatisfactory levels of service E or F except for the I-5 southbound Broadway and Main Street off-ramps in both the a.m. and p.m. peak hours. This is the same condition that would occur with implementation of the Original Project, as shown on DEIR Table 4.11-28. Thus, like the Original Project, the Modified Project would also result in less than significant impacts to freeway segments per Caltrans criteria. 2-179
