Mr. Mike Harrah Caribou Industries, Inc. March 9, 2020 Page 5 of 6 13141-04 TG Letter CITY OF SANTA ANA VMT SCREENING As stated in the City of Santa Ana Traffic Impact Study Guidelines (September 2019), projects may be screened out from completing a full VMT analysis if they have the potential to reduce VMT/SP and would consequently result in a less-than-significant transportation impact. In other words, the project should have the potential to reduce VMT/SP and be consistent with the Regional Transportation Plan (RTP) / Sustainable Communities Strategy’s (SCS) in order to be initially screened out. Projects located within Transit Priority Areas (TPAs) and low-VMT generating Traffic Analysis Zones (TAZ) have the potential to reduce VMT/SP and are consistent with the RTP/SCS. As illustrated in Appendices A and B of the City of Santa Ana Traffic Impact Study Guidelines, the proposed Project is located in a TPA and low-VMT generating TAZ. The Project is proposed to develop residential, office, retail, and restaurant uses. The mixed-use nature of the Project promotes low-VMT generation within the TAZ as well as the overall City. As discussed with the City of Santa Ana Planning Department, an increase of approximately 5,406 households is projected for the City based on the Orange County Transportation Analysis Model (OCTAM) from the base year of 2016 to the forecasted year of 2045. As such, the households proposed by the Project would be consistent with the growth anticipated in the RTP/SCS for the City. Orange County currently experiences a high demand and low supply of households in the region and the proposed Project would have the potential to serve the regional demand for households and is therefore consistent with the goals and objectives of the RTP/SCS. CONCLUSION Appendix B-1 of the 2017 Orange County Transportation Authority (OCTA) Congestion Management Program (CMP) identifies a change of three percent or more to the level of service (LOS) standard as a significant impact. The AM and PM peak hour intersection operations analysis are used to identify an intersection’s LOS during the peak hours. Since the proposed Project would result in a net reduction to the AM and PM peak hour trips in comparison to currently approved Project, the impacts are anticipated to be the same or less than those previously identified at off-site study area intersections. Therefore, no additional traffic-related impacts are anticipated as a result of the proposed development that is currently being contemplated in addition to those previously disclosed in the EIR.
