Grand Avenue Widening Project Environmental Impact Report Section 3.0 Under the 2020 Build scenario, the majority of intersections are forecasted to operate at LOS D or better with the exception of the Santa Ana Boulevard/I-5 HQV Ramps intersection which would operate at LOS F in the PM peak hour. This is primarily due to the reduction of the existing dual right turn lanes to a single right turn lane in order to provide a third southbound through lane through the intersection. Impacts of Alternative 1 Related to On Street Parking There is no on street parking on the project segment of Grand Avenue. Therefore, Alternative 1 will not result in impacts related to on street parking. No mitigation is required. Impacts of Alternative 1 Related to Consistency with SCAG Transportation Policies The SCAG transportation policies, from the Regional Comprehensive Plan and Guide and the Regional Mobility Element, are listed in Table 3.5-7. Alternative 1 was evaluated for consistency with each of these policies. As shown in Table 3.5-7, Alternative 1 is consistent with each policy, except for certain policies determined not to apply to this proposed project. Therefore, Alternative 1 will not result in adverse impacts related to SCAG transportation policies. Impacts of Alternative 2 Related to Transportation and Circulation Potential Traffic Impacts Under Alternative 2 Future Travel Lanes and Traffic Control Devices. The 2020 build scenario assumes the proposed improvements on Grand Avenue are in place by 2020. Under the 2020 build scenario, Alternative 2 is expected to perform the same as Alternative 1. Figure 3.5-5, provided earlier, shows the assumed 2020 intersection geometry under Alternative 2, reflecting the widened approaches on Grand Avenue. Future Traffic Volumes. Figure 3.5-6, provided earlier, shows the projected 2020 daily traffic volumes on the project segment of Grand Avenue under Alternatives 1 and 2. The daily midblock traffic volumes will range from 31,300 vpd south of Seventeenth Street to 36,600 vpd north of First Street. The 2020 AM and PM peak hour intersection turning volumes under Alternative 2 were shown earlier in Figures 3.5-7 and 3.5-8, respectively. LOS Analysis Results. Tables 3.5-5 and 3.5-6 provided earlier, shows the peak hour ICU and LOS values for the No Project Alternative and Alternative 2. As noted earlier, under the 2020 No Project Alternative, LOS E or F will occur at three study area intersections in at least one of the peak hours.
