Response 19: The commenter is incorrect. The Draft EIR references to number of daily trips (from the traffic <br />section) is associated with the average weekday trip rates. The traffic section, nor the traffic impact <br />analysis include or evaluate Saturday or Sunday daily rates. As such, the air quality modeling utilized <br />Saturday and Sunday trip rates based on ITE and CaIEEMod defaults which is appropriate and supported <br />by substantial evidence and not in conflict with the traffic section of the Draft EIR. <br />Comment 20: The comment states that the commercial -work trip length was manually increased in <br />CaIEEMod and the Draft EIR fails to provide any justification for this increase. The comment further asserts <br />that the model cannot be relied upon. <br />Response 20: The commenter is misstates and misquotes the data presented in the EIR. The section where <br />the commercial -work trip length was increased is related to the trucks accessing the existing industrial park <br />land use. A 40-mile trip length for trucks is justified and recommended as a truck trip length by SCAQMD <br />for industrial projects generating truck trips, the 40-mile trip length is derived from regional data <br />published by SCAG. <br />Comment 21: The comment asserts that the pass -by and diverted trip percentages are unjustified and <br />states that the model overestimates the existing land use's mobile -related operational emissions and should <br />not be relied upon to determine Project significance. The comment also states that the new values provided <br />in the Draft EIR were not adequately justified either because the reduction in pass -by and diverted trips is <br />not substantiated. The comment further states that for these reasons the air quality analysis is flawed and <br />the EIR should be amended. <br />Response 21: See Response to Comment 18 above. <br />Comment 22: The comment asserts that the City failed to include all relevant projects in its cumulative <br />Traffic impacts analysis and states that the analysis should be updated to include, the Congregate Care <br />Facility (two miles south of the Project site) and Staybridge Hotel in Irvine (one mile west of the Project <br />site). <br />Response 22: Cumulative Projects that are foreseeable at the date of the NOP are required to be <br />analyzed. A cumulative list was requested from the City of Irvine concurrent with release of the NOP. The <br />Cumulative projects list was provided by the City of Irvine Planning department and was dated <br />8/2/2019, with the NOP being dated 8/5/2019. The list provided by the City of Irvine did not include <br />the Congregate Care Facility, and only included a sign management plan for the Staybridge Hotel, which <br />would not create any traffic. Therefore, the City did its due diligence to include cumulative projects <br />expected to impact the opening year volumes. For the 2040 build out scenario, all cumulative projects <br />were included in the OCTAM model, therefore, the trips generated by cumulative projects are included in <br />the 2040 build out volumes. <br />Comment 23: The comment asserts that the Draft EIR fails to adopt feasible mitigation measures related to <br />construction air quality emissions and provides a list of measures to alleviate the significant impact of <br />construction -related emissions. <br />Response 23: As described in Section 5.2, Air Qualify, of the Draft EIR the Project would not result in a <br />significant impact related to construction emissions. As detailed in Tables 5.2-7 and 5.2-9 emissions from <br />construction activities would not exceed SCAQMD thresholds. Therefore, impacts would be less than <br />significant, and no mitigation measures are required. <br />75C-201 <br />
