EXHIBIT 2 <br /> A Santa Ana Boulevarci <br /> A COM Grade Separation Projen4 <br /> westbound right-turn at Santiago Street, followed by a northbound right-turn at Civic <br /> Center Drive to arrive at their destinations at or near Logan Street. Vehicles previously <br /> making a southbound right-turn from Logan Street to Santa Ana Boulevard would need to <br /> reroute to head north on Logan Street to westbound Stafford Street-Civic Center Drive, <br /> then either north or south on Santiago Street to reach their destinations. <br /> 7.0 EXISTING PLUS PROJECT CONDITIONS <br /> An existing plus project scenario was analyzed based on the addition of the project to the <br /> existing transportation network. For this evaluation, the geometric improvements as part of <br /> the project, coupled with the redistribution of traffic due to the termination of Logan Street <br /> were analyzed under an Existing plus Project scenario and were compared to existing <br /> baseline conditions. Figure 7 shows the resulting existing plus project AM and PM peak <br /> hour traffic volumes at the study area intersections. <br /> 7.1 Existing Plus Project Levels of Service <br /> A level of service analysis was conducted to evaluate existing intersection operating <br /> conditions during the weekday AM and PM peak hours with the proposed project. Table <br /> 8-1 summarizes the existing level of service at the study area intersections. Level of <br /> service calculation worksheets are included in Appendix G. <br /> Table 8-1 Existing plus Project Intersection LOS <br /> Existing Existing + Project <br /> Traffic AM Peak PM Peak AM Peak PM Peak <br /> Intersection Control Hour Hour Hour Hour <br /> ICU LOS ICU LOS ICU LOS ICU LOS <br /> Santiago St/Santa Ana Blvd Signal 0.479 A 0.538 A 0.532 A 0.588 A <br /> Delay LOS Delay LOS Delay LOS Delay LOS <br /> Grand Ave/Santa Ana Blvd Signal 28.1 C 25.7 C 28.1 C 25.7 C <br /> Santiago St/Civic Center Dr AWSC 11.4 B 12.3 B 11.6 B 12.4 B <br /> Logan St/Santa Ana Blvd TWSC 11.2 B 9.7 B n/a n/a <br /> SARTC Dwy/Santa Ana Blvd TWSC 9.7 A 11.8 B 9.7 A 11.8 B <br /> Fuller St/Santa Ana Blvd TWSC >50 F >50 F >50 F >50 F <br /> 1-5 SB Ramps/Santa Ana Blvd I Signal 25.5 C 26.4 C 1 25.6 C 26.4 C <br /> N otes: <br /> AWSC—all-way stop controlled intersection;TWSC—two-way stop controlled intersection;Delay expressed in seconds <br /> Bold denotes unacceptable LOS <br /> ICU reported for all signalized locations, except Caltrans facilities.Delay(reported in seconds per vehicle)is reported for all <br /> unsignalized intersections and Caltrans facilities.
