Traffic/Circulation Study Update In addition to the studies identified above, a focused traffic study is required that documents the methodology and results of an analysis performed to evaluate traffic operations for the proposed grade separation of the existing Santa Ana Boulevard/Orange County Transportation Authority (OCTA) Metrolink at -grade crossing in the City of Santa Ana, Orange County, California. The previous Traffic/Circulation Study, conducted in May 2012, evaluated a six -lane Santa Ana Boulevard (Major Arterial). However, the City of Santa Ana adopted the General Plan Mobility Element Update in April 2022. As part of that update, Santa Ana Boulevard between Santiago Street and the Interstate 5 (I-5) southbound off -ramp is proposed to be a four lane Primary Arterial per the Master Plan of Streets and Highways. The traffic study will therefore need to be updated to reflect a four -lane section of Santa Ana Boulevard. The project description is as follows: • East leg of Santiago Street/Santa Ana Boulevard to provide one left -turn, two throughs, and one right -turn lane • Termination of Logan Street north of Santa Ana Boulevard via construction of cul-de-sac • Intersection of Fuller Street/Santa Ana Boulevard: o One NB shared left/through/right o One SB shared left/through/right o One EB left -turn lane, one EB through lane, and one EB shared through/right-turn lane o One WB left -turn lane, one WB through lane, and one WB shared through/right- turn lane • West leg of I-5 SB off-ramp/Santa Ana Boulevard to provide dual left -turns and two through lanes • Focused Traffic Study Scenarios 1. Existing Conditions: This section will present an overview of the existing roadway system, transit network, and pedestrian/bicycle facilities within the study area, along with existing traffic volumes, and intersection and roadway levels of service. 2. Opening Year Conditions: Document methodology utilized to develop background opening year traffic forecasts, including ambient growth rates and traffic from future development projects 3. Future Year Conditions: Future year conditions to be based on OCTA's latest travel demand model, Orange County Transportation Analysis Model (OCTAM). 4. Existing plus Construction Conditions: An analysis of potential impacts during construction of the proposed project (i.e., temporary reduction in capacity). 5. Opening plus Project Conditions: Opening year traffic volumes with project roadway configuration.
