Ms. Selena Kelaher City of Santa Ana June 19, 2018 Page 7 of 8 11738-02 Letter.docx continue to provide left-turn access to the proposed Project and housing development on the southeast corner of Newhope Street & Edinger Avenue. Adequate storage is anticipated to be accommodated for the eastbound left turn lanes at both Project driveways. Opening Year (2019) With Project (Total Project) conditions traffic progression analysis worksheets are provided in Attachment I. CITY OF SANTA ANA PERFORMANCE CRITERIA AND THRESHOLDS OF SIGNIFICANCE The City of Santa Ana’s target LOS is D for roadway segments and arterial street intersections, except in major development areas. The City of Santa Ana has established the following thresholds of significance to determine whether the addition of project-related trips would result in a significant impact, and thus require mitigation: •A significant impact occurs at a study area intersection if the addition of project-related trips causes the intersection to change from an acceptable LOS (i.e., LOS D or better) to a deficient LOS (i.e., LOS E or F). •A significant impact occurs at a study area intersection if the addition of project-related trips results in a v/c increase of 0.010 and the intersection operates at a deficient LOS under pre- project traffic conditions (i.e., LOS E and F). RECOMMENDATIONS The addition of Project traffic for each of the 3 alternatives is anticipated to result in a v/c increase of less than 0.010. As such, the Project’s impact to the deficient intersection of Newhope Street and Edinger Avenue is less than significant. Therefore, no mitigation is necessary at the study area intersections based on the peak hour operations analyses. Although the traffic progression analysis indicates that there is queuing anticipated in the southbound left turn lane during the weekday AM and PM peak hours, this lane is striped as a two-way-left-turn lane north of the intersection for approximately 640-feet to W. Regent Drive. As such, restriping the storage to accommodate 300-feet of storage does not appear necessary as these vehicles would store within the painted two-way-left-turn lane. Similarly, although the traffic progression analysis indicates that there is queuing anticipated in the westbound left turn lane during the weekday AM and PM peak hour, the analysis also indicates that no storage is required for the West Driveway on Edinger Avenue. As such, there would be additional storage that could be accommodated within the existing two-way-left-turn lane to meet the weekday peak hour queuing demand. Both the West and East Driveways on Edinger Avenue are anticipated to have sufficient storage within the existing painted median to accommodate the anticipated eastbound left turn queues into the site. 4-125
