• The size of Site B provides advantages in locating a greater range of O &M <br />functions on the site which provides the opportunity to minimize duplication of <br />functions as the system expands and /or connects with other streetcar systems in <br />the future. <br />U Locally Preferred Alternative <br />The following describes the physical and operating characteristics of the recommended <br />LPA, Streetcar Alternative 1 . <br />5.5.1 Technology (Mode) <br />It is recommended that transit service be provided by <br />modern streetcars operating within existing streets in <br />mixed -flow traffic (the streetcar will share the travel <br />lane with other vehicles), consistent with the Streetcar <br />Alternatives analyzed in the EA/DEIR. For planning <br />purposes, the Siemens S7O short vehicle (see Figure <br />5 -1) was assumed since it is currently the only vehicle <br />approved by the California Public Utilities Commission <br />(CPUC) for streetcar operations in California. The Figure 5 -1: Siemens S7O Vehicle <br />vehicle is approximately 80 feet long and 8.7 feet wide. It provides seating for 60 <br />passengers and can accommodate a total of 150 passengers seated and standing. For <br />quick and convenient boarding, the vehicle is approximately 68 percent low -floor with a <br />low -floor height of 14 inches. Power would be supplied via an overhead electric line. <br />Other emerging streetcar technologies, including "wireless" and other vehicle options that <br />may be acceptable to the CPUC will also be considered as they become available during <br />the project development process. <br />5.5.2 Alignment (Route) <br />The recommended alignment (shown in Figure 5 -2) is consistent with Streetcar Alternative <br />1, with the streetcar traveling westbound from eastern terminus station at SARTC in Santa <br />Ana, along Santa Ana Boulevard, entering the Pacific Electric Right -of -way (PE ROW) west <br />of Raitt Street and continuing to the western terminus station in the northwest quadrant of <br />the intersection of Harbor Boulevard and Westminster Avenue in Garden Grove. <br />Eastbound, the streetcar will travel along the PE ROW and Santa Ana Boulevard to <br />approximately Parton Street, where the route will exit Santa Ana Boulevard and continue <br />along a public easement on the south edge of Sasscer Park. The streetcar will exit Sasscer <br />Park onto 4`h Street and continue along 4 " Street to Mortimer Street, where it will turn <br />north and reconnect with Santa Ana Boulevard, continuing east to the eastern terminus <br />station at SARTC. The route is approximately 4.1 miles in length. Six traction power <br />substations have been identified along the route to distribute electrical power to the <br />vehicles. <br />LPA Decision Report <br />July 2014 <br />55C -79 <br />5.8I Page <br />
