Analysis for Existing Traffic Conditions After obtaining the pertinent traffic data, the level of service (LOS) of traffic operations at study intersections and roadway segments will be analyzed for the existing conditions and existing -with -project conditions. The LOS analysis for both intersections and roadway segments will be performed in accordance with City guidelines. IBI Group has assumed that this work scope and analysis would be initiated following City adoption of new VMT thresholds and analysis procedures, which would reduce or eliminate the intersection LOS analysis required for the EIR. Instead, intersection analysis would be focused on areas with greater forecast land use changes to facilitate city planning for roadway improvements as part of the city's traffic fee program. Based on this assumption, IBI Group has scoped to analyze up to 40 study intersections and 60 study roadway segments for this analysis. For purposes of the development of the scope of work and budget for the traffic study, data collection has been assumed to be needed on up to 50 roadway segments (24-hour traffic counts) and 30 intersections (2 -hour AM and 2 - hour PM peak period turning movement counts) for the typical weekday. It is assumed that some of the traffic count data from the Circulation Element work can be reused. IBI Group will work with City staff to determine specifically when and where new counts should be completed, as well as the availability of count data for other locations to be included in the analysis IBI Group will also develop estimates of VMT based on existing land uses. This effort will be developed in part using the OCTA or SCAG regional travel demand models. At the outset of the assignment, IBI Group will work with the city and OCTA to determine the most appropriate model to use for developing VMT forecasts. As part of the VMT analysis, daily VMT forecasts will be developed for the existing -no -project conditions. The Existing Conditions Analysis will be conducted for the No Project, With Project, and Modified Project Alternative scenarios. Forecast Buildout Trak Volumes and Circulation Using the land use forecasts for General Plan buildout conditions provided by the City, IBI Group will develop future traffic forecasts for the city's roadway network. Future traffic forecasts will be developed using the latest available version of the OCTA regional model, in coordination with OCTA staff. IBI Group will provide model inputs for new socio- economic data that would correspond to the planned land use changes in order for OCTA to conduct model runs. The model forecasts will be used to generate traffic volume forecasts along major roadways within the study area and to identify changes to VMT fortrips generated within the city for use in the environmental review. We have assumed that all modeling efforts will be completed using OCTAM 4.0, OCTA's regional travel demand model and that modeling will be completed by OCTA. Should OCTA decline to conduct model runs and require IBI to conduct the modeling effort, revisions to this scope and the associated budget would be required to account for this effort. This scope of work also does not assume the development of a city -specific travel demand model as part of this effort. All modeling efforts will be conducted using OCTAM. It is assumed that the following land use and roadway network scenarios would be modeled forthe traffic study: • Year 2040 No Project— Existing General Plan/Socio-Economic Forecasts • Year 2040 With Project • Year 2040 With Modified Project Alternative This task will involve a complete description of the proposed land use changes in the General Plan for the Project and Modified Project Alternative, including any special transportation needs or considerations.
