California Department of Fish and Game U.S. Fish and Wildlife Services Section 3.10. Traffic and Transportation Demobilization Demobilization includes removing all construction equipment from the site, removal of all extra supplies and debris and final site cleanup. For a project of this size, demobilization would typically take at least several weeks. Construction-Related On-Highway Traffic In general, the Project would require about 3 non-specific delivery trucks per day. This includes tools, parts, and small supply, sanitary trucks, parcel delivery, and other various vehicles. Additionally, a project of this size would typically have at least one equipment service/refueling truck on-site every workday. Because many of the materials used during Project construction would be acquired locally from Project-related earthwork and dredging activities, it is assumed that the only basic earth materials imported into the site would be ballast rock for the railroad bed (Full Tidal Alternative only) and base rock and pavement for the Bay Trail (all Alternatives). Additionally, various minimal volumes of materials such as gravel and sand associated with contractor staging areas and specific construction features such as pump stations would be hauled into the site. Up to an estimated 35,000 cubic yards of clayey alluvial soil may be transported from Project areas north of Highway 37 to areas south of Highway 37 for levee core and cutoff trench material. It is anticipated that these trucks would be using Lakeville Highway and Reclamation Road to travel between sites. It is possible that site grading, core levee construction, and building demolition activities would be carried out simultaneously during the site preparation phase, as discussed above. Traffic would include a variety of trucks to deliver fuel, equipment, and supplies, and to facilitate site cleanup. An additional 5 miscellaneous trucks have also been factored in to account for any contingencies that may occur during Project construction. Additionally, it is estimated that approximately six 20-25 cubic yard dump trucks would travel on Lakeville Highway/Reclamation Road, at a rate of one trip per truck per hour for 8 hours each day, to move select fill from the Project area north of Highway 37 to areas south of Highway 37 for use in core levee construction. A similar number of trucks would be needed to haul demolition waste from the Dickson Ranch complex to the Redwood Sanitary landfill near Novato. Based on the assumptions discussed above and as shown in Table 3-10-2, it is estimated that as many as 108 daily round trips would be generated by on- Highway trucks during the greatest level of construction activity.

California Department of Fish and Game U.S. Fish and Wildlife Services Section 3.10. Traffic and Transportation Construction Personnel Vehicle Traffic The construction team includes equipment operators, support staff, forepersons, supervisors, safety, and inspection personnel. These persons generally arrive and depart the construction site each day in personal or company-issued vehicles. On typical projects, 70% of the crew vehicles are pickup trucks or SUVs and the rest are small to mid-sized cars. During the greatest level of construction activity, it is assumed that as many as 50 construction personnel would be required during site grading activities early in Project phasing. An additional 5 miscellaneous personnel vehicles have also been factored in to account for any contingencies that may occur during Project construction. Based on this assumption and as shown in Table 3-10-2, it is estimated that as many as 55 daily round trips would be generated by personnel vehicles on a daily basis during initial site preparation.
