APPENDIX D TRAFFIC IMPACT ANALYSIS SITE SPECIFIC REQUIREMENTS • Trip generation forecast including existing and cumulative projects. • Trip distribution forecast and trip assignment customized to accommodate the nature of project and cumulative project traffic. • Capacity analysis at the following intersections during both the morning (am) and evening (pm) peak periods. The City of Santa Ana utilizes the following values in calculating Intersection Capacity Utilizations (ICU's): 1600 vphpl for turning lanes, 1700 vphpl for through lanes, 5%clearance intervals. For Unsignalized intersection, the HCM shall be used. ➢ LIST OF INTERSECTIONS TO BE STUDIED ➢ LIST OF INTERSECTIONS TO BE STUDIED • Assessment and recommendation of existing and future configuration/striping and Level of Service (LOS) at all impacted areas including the following segment location(s). Please note road segment analysis shall be based on the Orange County MPAH methodology and the City of Santa Ana Circulation Element, No V/C capacity ratios in segment analysis: ➢ LIST OF ROADWAY SEGMENTS TO BE STUDIED ➢ LIST OF INTERSECTIONS TO BE STUDIED • Adequacy of storage length of the left turn pockets for: ➢ LIST OF INTERSECTION TURN POCKETS TO BE STUDIED ➢ LIST OF INTERSECTION TURN POCKETS TO BE STUDIED • Field inspect the subject roadway areas and inventory the existing street system as to base line width, striping patterns, and traffic. • Collect traffic counts on key site area roadways and intersections. These counts will include morning and afternoon peak hour turning movements as well as 24-hour daily volumes at locations between selected intersections. • Study shall include scenario analysis as follow: ➢ Existing Conditions —utilized to establish the current level or existing baseline of traffic operations. ➢ Existing Conditions — utilized to establish the current level or existing baseline of traffic operations with project. ➢ Project Opening Year No Project Conditions — establishes project opening year baseline to evaluate the proposed Project. ➢ Project Opening Year with Project Conditions — represents project opening year baseline traffic conditions. ➢ 2040 Project Design Year No Project Conditions — establishes future year baseline to evaluate the proposed Project.
