4.7 – Transportation Draft Environmental Impact Report February 2021 14800 W. Schulte Road Logistics Center 4.7-13 Single-loaded truck bays would be located on the south and north sides of Buildings A and B and on the west side of Building C. Building A would provide 42 loading docks, Building B would provide 43 loading docks, and Building C would provide 30 loading docks. Paved passenger vehicle parking areas would be provided along the northern and southeastern portions of the Project site near the frontage of Schulte Road and Quality Road. Truck/trailer parking would be provided in between Buildings A and B. Gated entry is proposed at key dock access routes for each building. In total, the Project site would include 111 stalls for trailers and 522 standard parking spaces for passenger vehicles and trailers. In addition, the Project would include internal drive aisles to facilitate on-site circulation. Access to the Project site would be provided via two driveways: • Driveway 1 on Schulte Road – 30-foot-wide, full-access (passenger cars only) driveway • Driveway 2 on Schulte Road – 50-foot-wide, full-access (passenger cars and trucks) driveway Internal Circulation The TIA (Appendix F) analyzed driveway throat lengths to determine availability of storage capacity within the Project site such that vehicles would not queue into internal intersections , along with adequacy of internal access road widths and circulation. The throat of the truck entrance from the first internal intersection is approximately 150 feet, which would accommodate one to two trucks. Additionally, a wide truck access aisle is provided for truck access to 42 truck docks to Building A and 43 truck docks to Building B. The passenger car entrance, located approximately 600 feet west of the truck entrance, would also provide a throat length of 150 feet, which would accommodate approximately six vehicles. Internal access roads of 26 feet wide would provide access to the three buildings, as shown in Figure 3-4, Site Plan, in Chapter 3, Project Description . Throat distances and internal access road widths are considered acceptable for this land use and would not result in hazardous design features . Impacts would be less than significant. Street Improvements To facilitate adequate on-site circulation and sufficient site access both passenger vehicles and trucks, and to ensure efficient off-site circulation on nearby roadway facilities, the Project would involve street improvements on Schulte Road, including adding a right-turn lane on eastbound Schulte Road for both driveways and widening a portion of westbound Schulte Road. These improvements would be constructed to accommodate the future build - out condition of Schulte Road. The TIA (Appendix F) also recommends addition of a westbound left-turn deceleration lane for both driveways to safely accommodate turning movements into the site along Schulte Road, which currently operates with an adopted posted speed of 50 mph and design speed of 60 mph. The Caltrans Highway Design Manual recommends 530 feet of deceleration length for a design speed of 60 mph, with the addition of storage length for two waiting vehicles (Caltrans 2019). The TIA recommends a storage length of 90 feet for two waiting vehicles (including one truck and one passenger vehicle), and a 90-foot taper (Appendix F); therefore, the total length of the left-turn lane and its bay taper would range from 535 to 770 feet. As noted in a memorandum from the County of San Joaquin to the City of Tracy, dated December 15, 2020, any specifics to queue lengths will be added as a requirement to the County’s Conditions of Approval to be determined and reviewed at the time of Plan Check and prior to the issuance of an encroachment permit (County of San Joaquin 2020c).
