7.A. - Page 114 LSA ASSOCIATES, INC. ROCKETSHIP REDWOOD CITY ELEMENTARY SCHOOL PROJECT SEPTEMBER 2016 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION Trip Assignment. The peak-hour trips generated by the proposed project were assigned to the roadway system in accordance with the trip distribution patterns discussed above. The assignment reflects the proposed right-turn only restrictions at the school inbound and outbound driveways on Charter Street and Bay Road,respectively during the peak hours before and after school. The turn restrictions at the school driveways and the turn restrictions at the Woodside/Spring intersection would affect the paths that vehicles use when approaching and departing the school. For vehicles approaching from the east on Woodside Road,it is expected that vehicles would turn left onto southbound Bay Road,right onto westbound Willow Street,left onto southbound Spring Street,and then left onto eastbound Charter Street. For vehicles prevented from turning left out of the site onto northbound Bay Road,there are two alternate paths available. It is expected that many vehicles that want to head east on Woodside Road would turn right onto westbound Kaynyne Street,turn right onto northbound Spring Street,then right onto eastbound Woodside Road. The traffic assignment assumes that half of all traffic destined for eastbound Woodside Road would use this path. The other half would turn left onto eastbound Douglas Avenue,left onto northbound Broadway,then right onto eastbound Woodside Road. It is expected that all vehicles that want to head west on Woodside Road would turn right onto westbound Kaynyne Street,right onto Middlefield Road,then left onto westbound Woodside Road. Existing and Existing Plus Project Conditions. The results of the intersection level of service analysis under Existing Conditions are shown in Table 8. The results indicate that eight of the nine study intersections currently operate at acceptable levels of service during the AM and/or PM peak hours.However,the intersection at Broadway and Woodside Road(Intersection 92),currently operates at an unacceptable LOS E during the AM and PM peak hours. In addition,traffic conditions were observed in the field to confirm accuracy of calculated LOS. Although operational issues at some of the study intersections were observed,overall,the LOS analysis appears to reflect actual existing traffic conditions. Existing Plus Project traffic volumes are shown in Figure 12.As shown in Table 8,under Existing Plus Project conditions,eight of the nine study intersections would continue to operate at acceptable levels of service and the intersection of Broadway and Woodside Road would continue to operate at LOS E during the AM and PM peak hours with the addition of project traffic. However,the added project trips would not have a significant impact at this intersection based on the City's level of service standards. Therefore,the proposed project would not result in a significant impact to the operations of any of the study area intersections during Existing Plus Project conditions. Background and Background Plus Project Conditions.The results of the intersection level of service analysis under Background Conditions are shown in Table 9. The results indicate that six of the nine study intersections would operate at acceptable levels of service during the AM and PM peak hours. However,the intersections at Broadway and Woodside Road(Intersection 42);Middlefield Road and Woodside Road(Intersection 94);which is a CMP intersection; and Bay Road and Charter Street (Intersection 95)would operate at an unacceptable LOS E during the AM and/or PM peak hours.
