• approximately 10 percent of the FL's total daily trips occurred during the AM peak hour and 6 percent occurred during the PM peak hour. The level of service (LOS) was analyzed for several conditions including Existing Plus Approved Projects and Cumulative Plus Project conditions. Based on this analysis, Forward contributed its fair share towards improvements at the affected intersections. In August 2004, a traffic study was performed for FL by TY Lin International/ CCS. The purpose of the traffic study was to assess the number of vehicles that could be added to the permitted 620 one-way trips without reducing the LOS at affected intersections below an acceptable level. The traffic study evaluated the same scenarios as presented in the 2002 Consolidated Forward Landfill EIR (i.e., existing plus approved projects and cumulative plus project) and concluded that 340 one-way trips could be added. 3.3.3 NOISE • Several noise studies were performed in the vicinity of FL in support of the 1993 Forward Landfill EIR, the 1994 Austin Road Landfill Expansion EIR, and the 2002 Consolidated Forward Landfill EIR. An acoustical analysis was also performed in 1999 for the BNSF Intermodal Yard. The noise readings were assessed based on the San Joaquin County Ordinance Code. Based on the County code, noise levels are not to exceed 65dB Ldn at usable outdoor spaces. The study performed in support of the 2002 Forward Landfill EIR found that there had been no appreciable change in noise levels since 1993. Daytime noise levels were found to be very low with individual auto and truck passages creating intermittent loud noise peaks. The data suggests that existing noise levels close to Austin Road are in the upper-60 dB Ldn range. At the facades of the closest houses, noise levels are in the mid-60 dB Ldn range. Due to the change in operating hours for FL, nighttime truck trips were also evaluated as part of the 2002 Forward Landfill EIR. Every truck trip before 7 a.m. or after 10 p.m. was counted as ten "noise equivalent" trucks in the Ldn calculation. • Forward Landfill-Project Description 3-9 BRYAN A.STIRRAT&ASSOCIATES J:\Allied\Forward\2007.0018 Lateral Expansion\Reports\Proj Descrip\021308 Final Proj Des\Sec 3.doc:2/13/2008)
