Draft Supplemental Environmental Impact Report Page IV.13-24 ' <br /> Forward Inc. Landfill 2018 Expansion Project <br /> would operate at unacceptable Level of Service F,with an average delay similar to year ' <br /> cumulative 2035 conditions if the existing landfill entrance on Austin Road is used. Thus,use of <br /> Newcastle Road for landfill access for the previously proposed project would not avoid the <br /> deterioration of levels of service at the Austin/Arch Roads,SR 99/Arch Road, and SR <br /> 99/Mariposa Road SB Ramp intersections to unacceptable conditions in the cumulative year <br /> 2035, and 2035 cumulative impacts with alternate access at Newcastle Road would be similar to <br /> those of the project evaluated in the 2013 EIR. ' <br /> Mitigation Measure B.7. (2013 EIR Mitigation Measure B.6). Improvements to Intersection 11, <br /> Arch Road/Austin Road,Southbound: The project shall contribute its fair share to the addition <br /> of one lane to provide one left-turn lane,two thru lanes,and one right-turn lane, as detailed in <br /> the TIA,Figures 12 and 13. <br /> Impact B.8. Potential Cumulative Impact to Mainline Roadway Operations. (Revises 2013 ' <br /> EIR Impact B.2) <br /> Cumulative Impacts to SR 99 Freeway Mainline ' <br /> As shown on Tables IV.B-13 and 14,below, the proposed project plus cumulative traffic(Short- <br /> Term and 2035)would not significantly affect SR 99 freeway mainline operating conditions. <br /> Table IV.B-13: Freeway Mainline Analysis-Short-term Conditions <br /> State Route 99 Existing Conditions+ Existing Conditions+ Project <br /> (Mariposa Rd.-French Approved Projects Approved Projects+ Impact <br /> Camp Rd.)
