All traffic counts at the 15 study intersections collected by IBI <br /> Group were conducted in 2009 as well. As part of the traffic study update, IBI will revise the analysis to reflect a <br /> 2012 existing year, consistent with the anticipated release date of the Notice of Preparation for the environmental <br /> document. The City of Santa Ana has directed IBI to use the 2009 traffic counts in the updated traffic analysis to <br /> avoid conducting new traffic counts. Two methods were discussed: applying a default growth factor of one <br /> percent annually to 2009 counts to estimate Year 2012 conditions, or conducting a few spot check traffic counts <br /> to confirm that 2009 counts are the same as 2012 or to identify an annual growth factor. This update requires <br /> the following new work elements that were not in the original scope of work: <br /> • Update Existing No Project Analysis - Pending direction from the City of Santa Ana, the existing no <br /> project analysis will be updated to reflect Year 2012 conditions. <br /> • Incorporate Existing Plus Project Analysis - The recent Sunnyvale court case highlighted the requirement <br /> that traffic studies prepared in support of CEQA documents must include an analysis of Existing Plus <br /> Project conditions.' This analysis was not included in the April 2010 TIA and will be added to the report <br /> as part of this update. <br /> Future Conditions <br /> The April 2010 TIA included the analysis of No Project and With Project conditions for a 2020 opening year and <br /> 2035 buildout year. With the change in the Existing Conditions year from 2009 to 2012, the analysis results for <br /> the Year 2020 and 2035 conditions will need to be updated. Future traffic volumes were obtained by applying <br /> annual traffic volume growth forecasts to existing traffic counts using forecasts produced by OCTA with the <br /> Orange County Transportation Analysis Model (OCTAM). We do not anticipate the need to obtain new OCTAM <br /> forecasts from OCTA. However, the Year 2020 and 2035 traffic volume forecasts must be updated with a <br /> baseline of the 2012 existing traffic counts to ensure consistency between analysis years in the report. <br /> Documentation <br /> IBI Group will update and revise the TIA report to reflect the analysis updates and additional analysis scenarios <br /> highlighted in the above tasks. A new report will be prepared and delivered for incorporation into the <br /> environmental document prepared for the project. <br /> Revisions to other subconsultant documents are not anticipated at this time. <br /> - VA Consulting: Utility Relocations <br /> - Cogstone: Archaeological Assessment <br /> - Urbana: Historical Resource Survey Report <br /> - Geologic Associates: Geotech Study <br /> - California Property Specialists, Inc.: Relocation Impact Statement - Draft [City consultant] <br /> <br /> <br /> <br /> <br /> On December 16, 2010, the Sixth District of the California Court of Appeal issued its decision in Sunnyvale West <br /> Neighborhood Association v. City of Sunnyvale, invalidating an environmental impact report (EIR) for a major roadway <br /> extension project. http://Ianduselaw.imbm.com/2011105/court-decision-changes-cega-related-traffic-impact-analyses.htmi <br /> <br /> <br /> 25F-36 <br />
