Task 3.2 - Mitigations For VMT-related impacts identified above, we will evaluate potential Transportation Demand Management (TDM) measures to reduce those impacts. If needed, we can work with the project team and the City to identify a feasible TDM program and will test the associated VMT reductions from that program through the methodology and information presented in the CAPCOA guide. The scope of services for this task will be determined in Task 1. Task 4.1- Data Collection It is assumed that intersection counts will be required for an intersection LOS analysis and roadway segment counts will be required for air/nose analysis. As such, this scope assumes data collection at up ten intersections and ten roadway segments during the AM and PM peak periods (7:00 — 9:00 AM and 4:00 — 6:00 PM). Counts will be collected during fair weather, while school is in session, and during a typical (non -holiday) Tuesday, Wednesday, or Thursday. Task 4.2 - Intersection Analysis The scope of work assumes analysis at up to ten intersections. As part of this assessment the following will be completed: Trip Generation, Distribution, and Assignment - we will estimate the number of weekday AM and PM peak hour trips generated by the Project through the methods established by the Institute of Transportation Engineers (ITE) Trip Generation Handbook, 11th Edition, 2021. We will estimate the origins and destinations of trips associated with the Project based on local traffic patterns, a select zone travel assignment from OCTAM, and discussions with City staff. Weekday AM and PM peak hour project trips will be assigned to the roadway network serving the site using the trip generation and trip distribution estimates. • Opening Year Forecasts — we will either interpolate OCTAM projections or assign trips from approved projects to study intersections and Project driveways to estimate growth through the opening year of the Project. We will add the project trip forecasts to the "no project" forecasts to develop traffic volumes for "with project" scenario at the study intersections. • Future Year Forecasts — we will utilize OCTAM to develop future forecasts at the study intersections and Project driveways after incorporating approved and pending projects in the study area. We will add the project trip forecasts to the "no project" forecasts to develop traffic volumes for "with project" scenario at the study intersections. • LOS Analysis — LOS analyses will be prepared for the analyzed intersections. Fehr & Peers will utilize the City of Santa Ana's LOS standard to identify intersection deficiencies and we will recommend potential improvements and appropriate fair share costs, if necessary. • Ramp Queueing Assessment — A queuing assessment will be performed at all Caltrans off -ramps to review storage capacity on Caltrans facilities, consistent with the latest Caltrans safety guidance. Task 4.3 - Non -Automotive Assessment As part of this assessment, Fehr & Peers will evaluate the project effect on bicycles, pedestrians, and transit. This will be completed by evaluating the project's consistency with existing and future infrastructure and policies supporting these modes. RFP NO.: 21-125 21
