Based on traffic volumes and speed limits obtained from the traffic analysis <br />prepared by DMJ I <br />Harris March 2008. Modeling is based on noise levels at 10 feet from the edge of the nearest traffic lane excludes noise from train traffic). <br />Railroad Sources <br />The railroad right -of -way is adjacent to Lincoln Avenue. As a result of the 2002 project implementation, the <br />right-of-way now consists of two main -line tracks instead of one. Noise generated by the train ,ruin line <br />contributes to the ambient noise environment. Noise from trains is generated by warning horns and crossing <br />bells when approaching at -grade crossings, and engines, exhaust noise air <br />9 t turbulence generated bar <br />cooling fans, and other gear operations. The interaction of steel wheels and rails generates three types of <br />noise: 1 rolling noise due to continuous rolling contact, ) impact Noise when a wheel encounters a <br />discontinuity in the running surfaces, such as a rail joint, turnout, or crossover, and 3 squeals generated by <br />friction on tight curves. When an at-grade crossing is present, a train is required by the federal Railroad <br />Administration (RRA) to sound a warning horn at a distance of one-quarter mile from all intersections at ar <br />maximum 110 dB , as measured at 100 feet. Horns are not used at crossings that have an established "quiet <br />zone." These quite zone crossings ,mist have enhanced safety measures. Currently, there are no quiet zones <br />established in the immediate vicinity of the project site. <br />There are currently 39 passenger trains that travel on the orange County Line through the project site <br />(Metrolinl 2008 and Amtrak 2008). f these" four occur between 10: 0 � <br />0 PIS and 7:0� 1. There are also <br />approximately four freight trains that travel on the orange county Line at night.' According to the 2002 EIR" <br />peak day travel activity on the Orange County Line is estirnated at 105 freight, intercity, and comm uter trains <br />by year 2020. Approximately 87 of these trains would occur in the daytime (83 percent) and 18 occur in the <br />nighttime 17 percent) between 10:00 PM and 7:00 AM. <br />' Based on BN F freight projections from the 2002 EIR. <br />Page 5.2-6 • The Planning Venter 1 r h 2009 <br />Resolution No. 2009 -034 <br />Page 72 of 130 <br />
