Occupancy Vehicle (HOV) Improvement project that is planned to be completed in 2020. This project includes the addition of one continuous HOV lane in each direction along the northbound and southbound I-5 between SR-55 and SR-57 and the I-5 HOV northbound entrance and southbound exist ramps at the intersection of N. Main Street/Edgewood Road-I-5 Ramps have been removed. Project Trip Generation The vehicle trip generation rates are from the Institute of Transportation Engineers' (ITE) Trip Generation (10th Edition) and are based on Land Use 221 - "Multi-family Housing (Mid-Rise)", which is consistent with the EIR analysis. Table T-1 shows that 278 units (22 units more than the Modified Project of 256 units) is estimated to generate 79 fewer a.m. peak hour trips, 96 fewer p.m. peak hour trips, and 1,186 fewer daily trips than the Original Project.

Attachment B. Because the Original Project resulted in less than significant traffic impacts, and the Modified Project would result in fewer peak hour and daily vehicular trips, the Modified Project would not result in any new or increased traffic impacts. Although the intersection of N. Main Street and Walkie Way would be modified to accommodate southbound left turns into the Project site, the traffic analysis modeling shows that the existing roadway network would be able to accommodate the change, as none of the traffic criteria thresholds would be exceeded, as detailed below. Therefore, no new or increased transportation, traffic, or circulation impacts would occur from implementation of the Modified Project. Existing Plus Modified Project Intersections: In the existing plus project with the Modified Project condition, Table T-2 shows that all of the study area intersections are forecast to operate at satisfactory levels of service except for the SR-22 eastbound ramps at Town and Country Road in both the a.m. and p.m. peak hours. This intersection is under the jurisdiction of Caltrans and currently operates at an unsatisfactory LOS E in the a.m. peak hour and LOS F in the p.m. peak hour. With the addition of traffic from the Modified Project, the intersection would continue to operate at an unsatisfactory LOS E in the a.m. peak hour and LOS F in the p.m. peak hour. This is the same conditions that would occur by the Original Project, as shown in Table 4.11-9 of the DEIR. Therefore, like the Original Project, the Modified Project would not result in exceedance of the Caltrans criteria, and no impacts at other intersections would occur in the existing plus Modified Project condition. Thus, overall impacts would be less than significant. Roadway Segments: In addition, as shown in Table T-3, all study area roadway segments are forecast to operate at satisfactory levels of service and implementation of the Modified Project would not cause an exceedance of LOS criteria on any of the roadway segments in the traffic study area. Therefore, impacts to roadway segments in the existing plus Modified Project scenario would also be less than significant, which is consistent with the EIR findings identified in DEIR Table 4.11-10. Queueing: As described previously, the Modified Project would implement changes to the Main Street and Walkie Way intersection geometrics that would provide a left turn into the Project site. This would result in a reduction in the storage length for the northbound left turn and the northbound through lanes at the intersection of Main Street/Walkie Way-Driveway, and for the southbound through lanes at the Main Street/Edgewood Road intersection by approximately 90 feet. Table T-4 shows the queueing in the existing without and with Modified Project conditions. As 2-168
