SCOPE OF SERVICES has been included have been assumed based on a review of existing project information and a preliminary review of the project site. If additional studies are identified during the environmental phase of the project a scope of work and cost will be submitted for approval by the City prior to their initiation. For each technical study the following submittals are assumed (additional submittals would be considered out of scope): Draft Technical Study (electronically to the City and then to Caltrans) Revised Draft Technical Study (electronically to the City and Caltrans for concurrent review) Final Technical Study for approval (electronically to the City and Caltrans for concurrent review and concurrence; assumes no further comments) 6.3.1 Traffic Analysis While the reduction in lanes is supported by preliminary review of average daily traffic, a focused review of peak hour travel is needed to confirm commute congestion is within City and OCTA standards. The study will evaluate the Santa Ana Boulevard corridor intersections using microsimulation software, SimTraffic, which is appropriate for closely spaced intersections in congested corridors. Microsimulation is required to evaluate how queues between intersections build up over space and time and potentially create gridlock between the closely spaced intersections. The following five intersections will be evaluated: 1. Santiago Street/Santa Ana Boulevard 2. Fuller Street/Santa Ana Boulevard 3. 1-5 SB Off-Ramp/Santa Ana Boulevard 4. Santa Ana Boulevard from Santiago Street to Fuller Street 5. Santa Ana Boulevard from Fuller Street to 1-5 SB Off -Ramp Fehr & Peers will collect new peak period turning movement traffic counts (7-9 AM & 4-6 PM) to prepare the existing conditions baseline condition Traffic counts will include pedestrian and bicycle counts to reflect the active uses in the corridor. A 24-hour vehicle classification count will also be CITY OF SANTA ANA �J SANTA ANA BOULEVARD GRADE SEPARATION ■ HARKTHOHAS conducted on Santa Ana Boulevard to understand heavy vehicle percentages. Fehr & Peers will collect traffic signal timing from the City of Santa Ana and Caltrans at the study locations. Fehr & Peers will conduct an existing conditions assessment that will evaluate 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. Fehr & Peers will prepare future traffic forecasts for the below scenarios utilizing OCTA's latest travel demand model, Orange County Transportation Analysis Model (OCTAM), which is consistent with Connect SoCa12024 (Southern California Association of Governments 2024 Regional Transportation Plan and Sustainable Communities Strategy with base year 2019 and future year 2050). A review of OCTAM land use will be conducted to confirm that land use growth assumptions are consistent with City expectations (Please note that Fehr & Peers recently conducted this model land use review as part of the City's Climate Action Plan and found consistency with City growth expectations). Two future model runs (with and without project) will be performed to understand potential redistribution with the project. 1. Opening Year Conditions: project opening year conditions assuming no project. An ambient growth rate will be developed by referencing OCTAM and the inclusion of relevant pending and approved development projects anticipated to be in operation by opening year. 2. Future Year Conditions: Future year conditions to be based on OCTAM forecasts with no project. 3. Existing plus Construction Conditions: An analysis of potential impacts during construction of the proposed project assuming that one lane in each direction will be provided throughout construction. 4. Opening plus Project Conditions: Opening year traffic volumes with project roadway configuration. 5. Future plus Project Conditions: Future year traffic volumes with project roadway configuration.
