Draft Supplemental Environmental Impact Report Page IV.B-28 Forward Inc. Landfill 2014 Expansion Project L Intersection Operations—Year 2035 Conditions Without the Proposed Project Intersection operations during the AM and PM peak hours at the study intersections without the project in year 2035 were analyzed in the 2013 EIR,because the previously proposed project would have generated traffic until 2039. This scenario assumes that driveway traffic volume at L the landfill remains as existing,with 212 truck loads per day and 35 employees. Peak hour traffic volumes that would occur at these intersections are shown in Figure IV.B-7, and levels of service are presented in Table IV.B-11. Under cumulative (no project) conditions in year 2035, all LOS values would be worse than Existing conditions with a number of locations operating at LOS F, summarized as follows: • Austin Road/Arch Road: LOS Fin the PM Peak :. • Route 99 at French Camp Road northbound ramp: LOS F in the AM and PM peaks • Route 99 at Arch Road: LOS F in the AM and PM peaks • Route 99 at Mariposa Road south bound ramp: LOS F in the AM and PM peaks Year 2035 Intersection Operations Deficiencies Traffic levels associated with cumulative development in year 2035 without the proposed project would cause the intersections identified above to operate at an unacceptable LOS F during one or both PM peak hours. In the Mariposa Lakes traffic study cited above, the poor performance of these intersections is attributed to an extremely high volume of traffic, and these i.. impacts are identified as Significant and Unavoidable. Year 2035 Cumulative-Plus-Project Traffic Volumes As discussed in Chapter III, Project Description, the 2014 Expansion Project at the Forward Landfill is projected to cease operations in year 2031. Thus, the 2014 Expansion Project would generate no traffic in the 2035 cumulative horizon year. Unlike the previously proposed project, the 2014 Expansion Project would not change the Year 2035 Conditions Without the Proposed Project shown in Figure IV.B-7 and Table IV.B-11. ,. Traffic volumes in the cumulative year 2035 would include traffic generated by development that occurs between the present time and 2035. Although the timing of this development cannot be predicted, it is likely that at least some of the development anticipated to exist in 2035 would have occurred by 2031, the last year of operation of the 2014 Expansion Project. In the ` years up to and including 2031, the 2014 Expansion Project traffic,which would generate the same volume of traffic as the previously proposed project evaluated in the 2013 EIR, would combine with other traffic to affect operation of local roads and intersections in those years. Because cumulative traffic in the years up to 2031 would be no greater than, and may be less than, traffic levels in 2035,the contribution of the 2014 Expansion Project to cumulative impacts in the years up to 2031 also would be equal to or less than the year 2035 cumulative impacts L evaluated in the 2013 EIR, as discussed below. Thus,the effect of the project in year 2035 cumulative conditions evaluated in the 2013 EIR is a worst-case measure of the effect of the 2014 Expansion Project in 2031. ` The year 2035 AM and PM peak-hour traffic volumes at the study intersections from the 2013 EIR are shown in Figure IV.B-8, and levels of service that would occur at these intersections and the project driveway are presented in Table IV.B-12. Traffic volumes and levels of service at i- these intersections resulting in 2031, including the contribution of the 2014 Expansion Project, would be the same as, or better than,those shown in IV.B-8 and Table IV.B-12.
