Draft Supplemental Environmental Impact Report Page IV.B-14 <br /> Forward Inc. Landfill 2018 Expansion Project <br /> Newcastle Road as Possible Access to Landfill <br /> As discussed under Impact IV.B-labove, the proposed project driveway currently operates at an <br /> acceptable level of service. In response to comments on the 2013 Draft EIR for the previously <br /> proposed project, landfill access via Newcastle Road was analyzed as an alternative to the <br /> existing entrance on Austin Road, and is summarized below.' <br /> Newcastle Road is a two-lane rural road with a north-south alignment. It extends south from <br /> Arch Road for about 1.5 miles, where the paved road ends. An unpaved extension continues <br /> south approximately another 1/4 mile where it terminates just north of Littlejohns Creek. The <br /> condition of the paved segment of Newcastle Road is weathered and cracked in some locations. <br /> The pavement is adequate for the low traffic volumes and very low truck volumes it currently <br /> carries. Several residences front the western side of Newcastle Road, and the N.A. Chaderjian <br /> Youth Correctional Facility and the O.H. Close Youth Correctional Facility are Camp located <br /> east of Newcastle Road. <br /> Use of Newcastle Road for landfill access would substantially increase truck traffic on that road, <br /> which would shorten the pavement life considerably, and would require installation of a second <br /> entry station with truck scales. In addition,Newcastle Road currently terminates north of <br /> Littlejohns Creek. Truck access to the Forward Landfill would require construction of a creek <br /> crossing, which could have adverse environmental impacts to the streambed. For these reasons, <br /> and because the existing project driveway operates, and would continue to operate, at a <br /> satisfactory level of service,use of Newcastle Road for access to the landfill does not appear to <br /> provide a better alternative. Because this alternative access is not proposed, no impact would <br /> occur. <br /> Impact B.2. Potential Project Impact to Mainline Roadway Segment Operations. (Revises <br /> 2013 EIR Impact B.2). <br /> Freeway Mainline Analysis <br /> Freeway mainline operation analyses were conducted to identify traffic operation on SR 99 and <br /> to evaluate the Project's potential impact on the freeway segment between Mariposa Road and <br /> East French Road during peak-hour operations. In addition, street segment operation analysis <br /> was conducted for the Austin Road segment between Arch Road and East French Camp Road. <br /> Table IV.B-7 shows SR 99 mainline peak-hour volumes and operations between Mariposa Road <br /> and East French Camp Road for all study scenarios. Freeway mainline LOS was determined <br /> based on density, which is calculated by the number of passenger cars per mile per lane divided <br /> by speed. Table IV.B-8 shows the freeway traffic operation ranking scale. As shown on Table <br /> IV.B-7, SR 99 freeway mainline between Mariposa Road and East French Camp Road would <br /> operate at acceptable conditions for all of the study scenarios, and the Project impact is minimal. <br /> Therefore, Project impacts to SR 99 mainline operations would be less than significant. <br /> ' Steve Fitzsimons,Republic ITS,Memo To: Sangeeta LewislLewis Engineering, Re:Forward Inc, <br /> Supplemental Analysis of Newcastle Road Access, February 19,2010. <br />
