III. ENVIRONMENTAL SETTING,IMPACTS AND MITIGATION MEASURES C. TRAFFIC CIRCULATION AND SAFETY The level of traffic increase generated by the proposed project, under maximum waste intake conditions, could affect operational conditions at the unsignalized Charter Way/Stockton Street intersection by increasing the number of vehicles waiting on Stockton Street to turn left onto Charter Way. Increased delays would result in a higher potential for drivers to attempt those movements when smaller-than-desirable gaps exist in the Charter Way traffic streams. As described in Impact C.1, and shown in Table III.0-6,above,the number of project-generated left turns from southbound Stockton Street onto Charter Way would be minimal (i.e., no more than six vehicles during the a.m. peak hour and one vehicle during the p.m. peak hour). Potential conflicts associated with the existing poor(LOS E/F)level of service, however, would be exacerbated by projected increases in left-turning vehicles generated by the project, and the impact would be considered to be potentially significant. Project-generated traffic increases on other roadways that provide access to and from the project site, and at other intersections on Charter Way,generally would not substantially worsen traffic conditions on those roads (see discussion of traffic impacts under Impacts C.1 and C.2,above). The physical and traffic characteristics of those roadways (e.g., traffic control at intersections, speed limits, sight distance,etc.)would safely accommodate the added traffic. Mitigation Measures Proposed as Part of the Project None. Mitigation Measures Identified in This Report Mitigation Measure C.3: Implement Mitigation Measures C.la(traffic signalization) and C.lb(diversion of vehicles away from Stockton Street). Significance After Mitigation: Less than Significant. Impact CA: The proposed project would generate turning Y movements b vehicles to and from site driveways. (Less than Significant) As shown in Figure II-2 in Chapter II,the proposed layout of access driveways for the project site would include two new driveways on Navy Drive, i.e., two-way access for the employee and visitor parking area(about 200 feet east of Pershing Avenue), and access for inbound trucks for the inbound scale and for transfer trucks for the loadout area(about 560 feet east of Pershing Avenue). Trucks traveling outbound from the site(from either the outbound scale or the loadout area)would access Navy Drive from Pershing Avenue. The provision of the different driveways would serve to reduce potential conflicts during turn movements by different traffic streams (e.g.,trucks and employee/visitor vehicles). The proposed location for the inbound scale would provide about 350 feet of storage length (including the scale itself), which would allow about 8 to 10 trucks (including the truck on the scale)to queue on-site. On the basis of the expected maximum rate of incoming trucks and a conservatively high average service rate (i.e.,the time needed for a truck to be weighed),the proposed storage length would fully accommodate the estimated queues without impeding traffic Storkton Sravenger Transfer Station Erpansion III.C.12 ESA/990190
