Draft Supplemental Environmental Impact Report Page IV.B-16 Forward Inc. Landfill 2014 Expansion Project Notes: Level of Service based on worst approach delay for two-way stop controlled intersections and average delay for all-way stop-controlled and Signalized intersections. Minor Stop=Stop sign-controlled. Only the minor street stops. App=Approach,Avg=Average Newcastle Road as Possible Access to Landfill L As discussed under Impact B.8,below, the proposed project driveway currently operates at an acceptable level of service, and would continue to operate at an acceptable level of service 6. under near-term and 2035 cumulative conditions. In response to comments on the 2013 Draft EIR for the previously proposed project, landfill access via Newcastle Road was analyzed as an alternative to the existing entrance on Austin Road, and is summarized below.' L Newcastle Road is a two-lane rural road with a north-south alignment. It extends south from Arch Road for about 1.5 miles, where the paved road ends. An unpaved extension continues south approximately another 1/4 mile where it terminates just north of Littlejohns Creek. The j` condition of the paved segment of Newcastle Road is weathered and cracked in some locations. The pavement is adequate for the low traffic volumes and very low truck volumes it currently - carries. Several residences front the western side of Newcastle Road, and the Northern California Youth Correctional Center is located east of Newcastle Road. Use of Newcastle Road for landfill access would substantially increase truck traffic on that road, which would shorten the pavement life considerably, and would require installation of a second 60 entry station with truck scales. In addition,Newcastle Road currently terminates north of Littlejohns Creek. Truck access to the Forward Landfill would require construction of a creek crossing, which could have adverse environmental impacts to the streambed. For these reasons, and because the existing project driveway operates, and would continue to operate, at a satisfactory level of service,use of Newcastle Road for access to the landfill does not appear to provide a better alternative. Because this alternative access is not proposed,no impact would k occur. L Impact B.2. Potential Project Impact on Travel Speed on Austin Road. (Revises 2013 EIR Impact B.2). Operations of the road segment along Austin Road between the project driveway and Arch Road were evaluated in the 2012 Republic ITS report, in accordance with the guidelines of ` Chapter 20 of the Highway Capacity Manual (TRB, 2000). Since the proposed project would add truck traffic to the study segment, the percent of trucks was increased for the "With Project" scenarios compared to the "No Project" scenarios. Table IV.B-6 shows the results of the evaluation for the near term scenarios. All speeds would be in the acceptable range of LOS A. Southbound values are all LOS A because southbound traffic is uncontrolled at the project driveway. After the vehicle speed analysis was conducted by Republic ITS in 2012, traffic signals were installed at the California Heath Care Facility entrance on Austin Road. When this traffic light is red for vehicle approaches on Austin Road, it may result in a small decrease in vehicle speed along the study segment of Austin Road. However, since the projected LOS levels are A, the traffic signal is not expected to worsen the travel speed LOS to unacceptable conditions.
