LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2-17-3881-1 Tustin Avenue Retail, Santa Ana N:\3800\2173881 - Tustin Avenue Retail, Santa Ana\Report\3881 - Tustin Avenue Retail, Santa Ana TIA 03-13-18.doc 34 12.3 Year 2019 Traffic Conditions – Caltrans Methodology Table 12-3 summarizes the Year 2019 peak hour HCM level of service results at the two (2) state- controlled study intersections within the study area. The first column (1) of HCM/LOS values in Table 12-3 presents a summary of existing traffic conditions. The second column (2) presents Year 2019 cumulative traffic conditions based on existing intersection geometry, but without any project generated traffic. The third column (3) presents future forecast traffic conditions with the addition of Project traffic. Column four (4) indicates whether the traffic associated with the Project will have an impact based on the LOS standards defined in this report. The fifth column (5) presents the resultant level of service with the inclusion of recommended traffic improvements, where needed, to achieve an acceptable level of service. 12.3.1 Year 2019 Cumulative Traffic Conditions An analysis of future (Year 2019) cumulative traffic conditions indicates that with the addition of ambient traffic growth and related projects traffic, both state-controlled study intersections currently operate an acceptable LOS C or better during the AM and PM peak hours. 12.3.2 Year 2019 Cumulative Plus Project Traffic Conditions Review of columns (3) and (4) of Table 12-3 indicates that traffic associated with the proposed Project will not significantly impact any of the two (2) state-controlled study intersections, when compared to the LOS standards and significant impact criteria specified in this report. Appendix E presents the Caltrans level of service calculation worksheets for the two (2) state- controlled study intersections. 2-112
