2101 and 2109 E Santa Clara Avenue <br />April 2, 2024 <br />Page 11 <br />A Transportation Analysis was prepared for the proposed project by Urban Crossroads, <br />dated August 16, 2023. The findings of the analysis were summarized in Section 4.17 <br />(Transportation) of the IS/MND, and the Transportation Analysis in its entirety is <br />included as Appendix K to the Draft IS/MND. The Transportation Analysis included a <br />Level of Service (LOS) analysis, which is a qualitative description of traffic flow based <br />on several factors including speed, travel time, delay, and freedom to maneuver. <br />Moreover, the project specific Transportation Analysis conducted a traffic signal warrant <br />analysis to determine the potential need for installation of a traffic signal at an otherwise <br />unsignalized intersection, including at the intersection of the Driveway 1 (located along <br />Santa Clara Avenue) and Santa Clara Avenue, and the intersection between Tustin <br />Avenue and Driveway 2 (located along Tustin Avenue). Lastly, a Vehicles Miles <br />Traveled (VMT) Screening Evaluation was prepared by Urban Crossroads, dated <br />December 11, 2023 and included as Appendix L to the Draft IS/MND. <br />The Transportation Analysis addressed traffic conditions for multiple different scenarios, <br />including existing (2022) baseline conditions, existing with Project conditions, opening <br />year (2023) cumulative without Project conditions, opening year cumulative with Project <br />conditions, horizon year without Project conditions (2040), and horizon year with Project <br />conditions. A queuing analysis was performed for the left turning movements at the <br />intersection of Tustin Avenue and Santa Clara Avenue to assess vehicle queues along <br />the roadways and prevent dangerous intersections. In summary, the intersection left <br />turning movements currently experience and are anticipated to experience acceptable <br />queuing during the peak hours based on the 95th percentile peak hour traffic flows for <br />each of the scenarios proposed above. The queuing analysis findings are presented in <br />Appendix K to the Draft IS/MND. <br />As concluded by the Transportation Analysis, the addition of project traffic would not <br />trigger the City of Santa Ana's significance criteria, and no traffic signal is warranted for <br />either intersection, intersection of the Driveway 1 (located along Santa Clara Avenue) <br />and Santa Clara Avenue, and the intersection between Tustin Avenue and Driveway 2 <br />(located along Tustin Avenue). Moreover, the Transportation Analysis performed a <br />drive -through analysis to determine if the proposed circulation plan provided adequate <br />on -site drive -through storage capacity to accommodate the peak on -site vehicle <br />demand. Ultimately, the drive -through analysis suggested that the project would provide <br />stacking accommodations for approximately 16 vehicles within the drive -through, and <br />there would be sufficient capacity to accommodate average and peak vehicle demands <br />for the proposed project. <br />In 2013, the State of California signed into law Senate Bill 743 (SB 743), which changes <br />how transportation impacts are analyzed under the California Environmental Quality Act <br />(CEQA) in order to help reduce transportation impacts. Specifically, in an effort to <br />reduce greenhouse gas impacts and create long-term sustainability, SB 743 changed <br />the standard for evaluating transportation impacts under CEQA from a LOS standard to <br />Vehicle Miles Traveled (VMT) standard. This statewide mandate went into effect July 1, <br />
