East Stockton Transfer and Recycling Station Modification Traffic Assessment ' September 19, 2011 Page 2 - Conduct Field Study to Observe Queuing Patterns in Vicinity: This task determined whether any queuing issues in turn lanes exist at the surrounding intersections. The intersection ' approaches included: - Filbert Street/Weber Street - Filbert Street/ SR 4 WB ramps Filbert Street/ SR 4 WB ramps - Filbert Street/ SR 4 EB ramps - Filbert Street/ SR 4 EB ramps - Determine Truck Patterns for Site Expansion: This task included review of the Project Description (PD) and Initial Study (IS) for the ESTRS to determine truck arrival and departure procedures. The surrounding neighborhood was also considered with regard to the projected increase of recycling—related traffic to and from the site. - Evaluate Site Access: The proposed site plan was reviewed to determine if a surge in trucks would occur with the plant expansion and whether adequate queuing is available for inbound trucks. 1 Conduct Field Study to Observe Oueuin2 Patterns in Vicinity Access to the site will remain along Weber Street; however, as noted, the facility access will be I moved to west of F Street. A site visit was conducted on September 2, 2011. Five movements along Filbert Street were observed. The E Street/ Weber Street intersection was also observed. Almost all project-related truck traffic used Filbert Street to access the existing site. It is assumed that these traffic patterns will remain with the expansion completed. Fifteen minutes observations were made at four intersections, including Weber Street / E Street, Filbert Street / Weber Street, Filbert Street/ SR 4 WB Ramps and Filbert Street/ SR 4 EB Ramps. Weber Street / E Street - This intersection is located west of the recycling site. One truck was noted during the field observations in the a.m. peak hour making a southbound left turn along iE Street to Weber Street. No excessive queues were observed at this intersection, and the single truck was able to complete the turn. Filbert Street / Weber Street / Myrtle Street - During the a.m. peak hour trucks were observed making a left turn to access the project site. The existing left turn lane is about 100', and appeared to provide adequate storage for these inbound movements. The queues did not spillback to the westbound ramps intersection; however, it was noted that southbound through vehicles would spillback from the westbound SR 4 ramps intersection and block the intersection on their approach to the on-ramp. In addition, the westbound to southbound movement had a continual queue of 15 to 20 vehicles as they also waited to access the westbound SR 4 on-ramp.
