Draft Supplemental Environmental Impact Report Page IV.13-20 <br /> Forward Inc. Landfill 2018 Expansion Project <br /> Year 2035 Cumulative Intersection Impacts ' <br /> Study intersections LOS for the Cumulative 2035 traffic conditions were evaluated in the 2018 <br /> Traffic Impact Assessment with and without the Project to identify project impact for the <br /> cumulative condition scenario.The 2035 traffic volume forecasts for the study intersections <br /> were obtained from the traffic reports prepared for the Mariposa Lakes Development and the <br /> Tidewater Crossing Development,with results derived from the San Joaquin County Regional ' <br /> Traffic Model prepared by The San Joaquin County Association of Governments. <br /> Table IV.B-12 shows study intersections LOS for cumulative conditions along with a <br /> comparison with existing and short-term conditions LOS.Figure IV.B-7 shows the anticipated ' <br /> traffic volumes for the 2035 traffic condition with the Project.As indicated, eight study <br /> intersections are projected to operate at unacceptable conditions without any improvements. <br /> However, a large number of roadway and signalization improvements are required as ' <br /> mitigation or otherwise included in the other approved projects.These are summarized in the <br /> 2018 TIA. Implementation of these improvements would reduce the significantly impacted <br /> intersections to the following four: ' <br /> • SR 99 SB On-off Ramps&E. French Camp Rd., (AM and PM peak hours) <br /> • SR 99 Urban Interchange&Arch Rd. (AM and PM peak hours) <br /> • SR 99 SB On-off Ramps&Mariposa Rd. (AM and PM peak hours) <br /> • SR 99 NB On-off Ramps &Mariposa Rd. (PM peak hour) <br /> The proposed Project would add traffic to the unacceptable levels of service at these <br /> intersections. Although the project's contributions would be small,based on County policy <br /> they would be considered cumulatively considerable. The intersections were evaluated for <br /> mitigation potential,however there is not adequate land available at the required locations to <br /> further improve these intersections. Therefore, the Project's cumulative contribution would be <br /> considered a significant unavoidable impact. <br /> In addition, the Project would generate a significant cumulative contribution to a significant <br /> impact at the following intersection. <br /> • Arch Rd. &Austin Rd(AM and PM peak hours) <br /> As shown on Table IV.B-12,implementation of Mitigation Measure B.7,below, would reduce <br /> this impact to a less-than-significant level. <br /> Newcastle Road Access <br /> As described under Impact B.1, an alternate access to the landfill at Newcastle Road was <br /> considered in the 2013 EIR. That EIR found that,under year 2035 cumulative conditions with <br /> the use of Newcastle Road for landfill access, the intersections of Austin Road/Forward <br /> Driveway and Arch/Newcastle Road would operate at acceptable levels of service,but the ' <br /> Austin/Arch Roads, SR 99/Arch Road, and SR 99/Mariposa Road SB Ramp intersections <br />
