in height. Each building of these buildings would have an adjacent parking structure. Two parking structures <br />would provide 7-levels of above ground parking and two would provide 6 levels of above ground <br />parking. The tallest point of the Project would be approximately 94 feet from the ground level, which <br />would be at the top of the architectural trim of the 6- story buildings. The height and size of the proposed <br />structures are also shown in the Draft EIR Figure 3-4, Proposed Site Plan and Figures 5.1-9 through 5.1-11. <br />The tallest building structures are featured on Draft EIR Figures 5.1-10 and 5.1-1 1. The height and size of <br />the proposed structures (including the parking structures) are evaluated on Draft EIR pages 5.1-24 through <br />5.1-32, which determined that the Project would not substantially degrade the existing visual character or <br />quality of public views of the site and its surroundings and would not conflict with applicable zoning and <br />other regulations governing scenic quality. As the information discussed by this comment is included in the <br />EIR, and the analysis has determined that impacts would be less than significant, recirculation of the Draft <br />EIR is not warranted. <br />Comment 10: The comment asserts that the changes to the Project that will have new, significant <br />undisclosed energy and air quality impacts. The comment states that the Final EIR discloses that rather than <br />having a 24-month construction period as originally discussed, the Final EIR states that the Project will be <br />under construction for 27 months. <br />Response 10: The Project has always assumed a 27-month construction period, as detailed in Section 3.0, <br />Project Description (page 3-19), of the Draft EIR. The comment refers to a typographical error on page <br />5.4-5 in the Draft EIR, which has been corrected in the Final EIR. In addition, the energy discussion includes <br />other references to the 27-month construction period, which was evaluated in the air quality modeling, and <br />is included as Appendix B of the EIR. Overall, the EIR discloses the air quality emissions and energy usage <br />of the project, which were determined to be less than significant. No new or additional impacts related to <br />air quality and energy would occur. <br />Comment 11: The comment asserts that the Draft EIR fails to conduct a quantified HRA as a result of diesel <br />particulate matter (DPM) emissions that would be emitted during project activities for nearby existing <br />sensitive receptors. The comment asserts that the construction and operational health risk impacts posed to <br />nearby existing sensitive receptors resulting from the proposed project need to be quantified and <br />compared to applicable thresholds. The comment states that because the LST method can only be applied <br />to criteria air pollutants, this method cannot be used to determine whether emissions from DPM, will result in <br />a significant health risk impact to nearby sensitive receptors. The comment further states that the EIR should <br />compare emissions from the project to the SCAQMD DPM emissions cancer risk threshold of 10 in one <br />million; and has attached a screening level analysis that asserts that the Project would exceed the <br />threshold. <br />Response 11: The project does not propose significant operational sources of DPM emissions or other toxic <br />air contaminants (TACs), such as freeways and high -traffic roads, commercial distribution centers, rail <br />yards, ports, refineries, chrome platers, dry cleaners, or gasoline stations. Only diesel delivery trucks would <br />be considered a TAC source, of which the mixed -use Project would generate a limited amount that would <br />not result in a health risk at the nearby residential receptors. <br />Additionally, the air quality analysis for the proposed project (Appendix B of the Draft EIR and Section <br />5.2, Air Quality, of the Draft EIR) evaluates both construction and operational emissions that would be <br />generated by the proposed Project and could affect nearby existing sensitive receptors. SCAQMD does <br />not state that construction based HRAs are required. However, as directed by SCAQMD, the local <br />significance thresholds (LSTs) are used to evaluate potential impacts from particulate matter emissions to <br />sensitive receptors in the project's vicinity from project construction. As shown in Table 5.2-9 of the Draft <br />EIR, local construction related emissions would not exceed SCAQMD LST thresholds. <br />75C-195 <br />
