changes will be used to develop socio-economic data forecasts to incorporate into the OCTA model to develop project trip generation forecasts for the weekday peak hour and daily trip volumes. The model forecasts will be used to account for mode split and interaction between adjacent land uses. For both alternatives, IBI Group will post -process forecast intersection volumes using a procedure based on the Transportation Research Board methodology to generate forecast turning movements at intersections. Post -processing refines the model link level forecasts to produce reasonable turning movement volumes at the intersections. VMT forecasts for the General Plan buildout condition and no -project buildout condition will be developed using the OCTA regional model. IBI Group will also provide PlaceWorks with the socio-economic data from the model used in the development of the traffic and VMT forecasts for TAZs in the City of Santa Ana. If the information is available from the regional model, IBI Group will also provide fleet mix for the VMT results. Analysis for Future Forecast Traffic Conditions After obtaining the pertinent traffic data, the level of service (LOS) of traffic operations at the 40 study intersections and 60 roadway segments will be analyzed for the buildout traffic condition. The peak hour and daily volumes, lane configurations, and controls will be presented graphically in the study report. The results of a level of service analysis based on existing lane geometry and peak hour volumes for the existing -no -project and existing -with -project conditions will be tabulated in the report. Intersection analysis will be conducted using the ICU methodology for intersections under City jurisdiction. The appropriate methodology for other agency intersections (e.g., Caltrans) will conform to those agencies' requirements. This scope of work does not assume analysis of future traffic conditions on Caltrans -operated freeway segments. Should Caltrans identify the need to analyze traffic conditions for freeway segments within or near the vicinity of Santa Ana, this scope and budget would need to be amended to incorporate this work effort. Traffic volumes for the three analysis scenarios identified above will be forecast for buildout year analysis. The future peak hour and daily volumes will be presented graphically, and the results of the level of service analysis will be tabulated in the report. Locations, if any, where the project is forecast to create significant impacts will be identified based on the appropriate agency's thresholds. At locations with identified significant impacts, IBI Group will identify specific mitigation measures to address these impacts. The intersections will be field reviewed to verify the preliminary feasibility of the proposed mitigation measures, and the resulting level of service at the impacted locations will be quantified in the report. VMT forecasts developed using the OCTA model will be analyzed consistent with OPR guidelines and any established City of Santa Ana VMT analysis guidelines. Administrative Draft Traffic Study IBI Group will prepare an administrative draft of the traffic study that will be submitted to the City for review and comment. Following receipt of comments from Citystaff, IBI Group will revise the document. Draft Traffic Study The draft traffic study will incorporate comments received from the City on the administrative draft and will be the draft document issued for the 45 -day public review as part of the Draft EIR.
