IBI Group <br />City of Santa Ana —April 27, 2017 <br />modifications to the OCTA model assumed mode split for automobiles, bicycles, and pedestrians. <br />The traffic analysis will include analysis of the previously identified 78 study intersections and 52 <br />roadway segments. <br />IBI Group will coordinate with OCTA to provide inputs for a single new OCTAM regional travel <br />demand model run to develop updated Year 2040 traffic forecasts that include the deletion of the <br />PE ROW and mode split modifications (as well as all previous modifications to the MPAH roadway <br />network identified by the city in the original contract and Amendments No. 1 and No. 2). This <br />model run will utilize the new version of OCTAM, which results in a change in the traffic study <br />horizon year from 2035 to 2040. This will require updates to the baseline future no project traffic <br />analysis as well. IBI Group will post - process the updated model forecasts obtained from OCTA to <br />update our June 2016 draft traffic study for both the 2040 no project and with project scenarios. <br />Based on comments received from OCTA, the traffic analysis will also be amended to incorporate <br />analysis of transit travel times and performance on up to 10 corridors within the City of Santa Ana. <br />This analysis will be based on transit travel time and performance data provided to IBI Group by <br />OCTA, and will be summarized as a distinct section within the updated traffic impact study. <br />In addition to the preparation of an updated traffic impact analysis for the Circulation Element <br />update, IBI Group will also work with the City to develop a proposed Vehicle Miles Traveled (VMT) <br />threshold and analysis procedures for incorporation into the Circulation Element and the city's <br />traffic impact standards. Traffic impact guidelines may be refined to reflect the Governor's Office <br />of Planning and Research (OPR) recommendation to replace traditional level of service with VMT <br />as the primary measure of transportation impacts. IBI Group will provide the city with a technical <br />memo summarizing recommendations related to establishing a VMT threshold and VMT analysis <br />procedures. <br />IBI Group will incorporate a VMT analysis into the traffic impact study. VMT data will be derived <br />from travel patterns extracted from the OCTAM regional travel demand model. The approach to <br />calculating citywide VMT targets will be consistent with the OPR's Revised Proposal on Updates <br />to the CEQA Guidelines on Evaluating Transportation Impacts in CEQA, Implementing Senate Bill <br />743 (January 2016). <br />This task also assumes time for attendance at up to two additional meetings with OCTA staff to <br />discuss the mode split modifications and VMT estimates. <br />Additionally, IBI Group has incorporated an additional $13,115 into the budget for this task to cover <br />the work efforts previously incurred and approved by the City in our Amendment dated October <br />2014 that was approved by City Council, but not executed by the City. <br />Task 8: Prepare CEQA Document <br />The tasks associated with restarting and updating the CEQA environmental analysis work are <br />described below. <br />Task 8.1: Proiect Initiation <br />We have not included additional hours for this task. The updated project description is fairly <br />comprehensive, and the work to understand and update the description is included in Task 2— <br />Notice of Preparation (e.g. project description update), Task 5— Screencheck EIR, and Task 11— <br />Project Management. <br />25G -20 <br />
