11738-02 Letter.docx June 19, 2018 Ms. Selena Kelaher City of Santa Ana 20 Civic Center Plaza Santa Ana, CA 92702 SUBJECT: ARCHANGEL MICHAEL COPTIC ORTHODOX CHURCH FOCUSED TRAFFIC ASSESSMENT Dear Ms. Selena Kelaher: The purpose of this focused traffic assessment is to identify potential impacts and improvement needs to study area intersections as a result of the development of the proposed Project located at 4405 West Edinger Avenue (referred to as “Project”) in the City of Santa Ana. It is our understanding that the Project is proposing opening the existing mezzanine to provide pew seating for approximately 109 parishioners in the existing church’s sanctuary building and is proposing the construction of a new two-story 9,928 square foot Community Service Building, which is not proposed to be utilized concurrently with the sanctuary building. However, for the purposes of this focused traffic assessment, each component of the proposed Project has been evaluated both independently and combined (concurrent activities for the church and the community service building) in an effort to conduct a conservative analysis. As part of the Project, the church will also be moving the community service uses from the sanctuary’s basement to the new community service building and the sanctuary’s basement will be utilized for ancillary storage. The preliminary site plan is shown on Exhibit 1. SUMMARY OF FINDINGS The study area evaluated for the purposes of this focused traffic assessment is shown on Exhibit 2. Based on the results of this traffic evaluation, the intersection of Newhope Street and Edinger Avenue currently operates at a deficient level of service (LOS) (i.e., LOS E) during the weekday PM peak hour only and would continue to operate at a deficient LOS in the future. However, the Project’s contribution to this intersection is not anticipated to exceed the City’s significance threshold for deficient intersections. As such, the Project’s impact at the intersection of Newhope Street and Edinger Avenue is less than significant and no mitigation is required. Weekday AM and PM peak hour queues are anticipated to exceed the current striped storage lengths for the southbound and westbound left turn lanes at the intersection of Newhope Street and Edinger Avenue. However, the existing striped two-way-left-turn lane for both the southbound and westbound left turn lanes appear to provide adequate storage to accommodate the peak hour queues. The two- way-left-turn lane striped along Edinger Avenue is anticipated to accommodate adequate storage for the eastbound left turn movement for both the West and East Driveways serving the Project. 4-119
