5 LESS -THAN -SIGNIFICANT ENVIRONMENTAL EFFECTS WITH MITIGATION INCORPORATED Explanation of the Rationale: The rationale and facts supporting the above finding are fully developed in Section 4.1, Air Quality, pages 4.1-48 through 4.1-51 of the Draft Supplemental EIR. The following presents a summary of that rationale: The Project would not have a considerable contribution to cumulative impacts related to consistency with applicable air quality plans or regional and localized emissions with the implementation of Project -Specific MM AQ-1, to reduce the Project's operational emissions of VOCs and its contribution of ozone precursors to the SCAB to below the SCAQMD's threshold of significance. Additionally, GPU PEIR MM AQ-1 would require the use of construction equipment rated by the USEPA as having Tier 4 emissions limits for engines between 50 and 750 horsepower to reduce the carcinogenic and acute hazard risks. Therefore, cumulative impacts related to consistency with applicable air quality plans and regional and localized emissions were determined to be less than significant after mitigation. 5.2 CULTURAL RESOURCES Threshold C-2: The Project would not cause a substantial adverse change in the significance of an archaeological resource pursuant to State CEQA Guidelines Section 15064.5 with the imDlementation of mitiaation. Findings: The City finds that changes or alterations have been required in, or incorporated into, the Project, which avoid or substantially lessen the significant environmental effect as identified in the Final Supplemental EIR. Specifically, the City finds that the following mitigation measure shall be implemented to reduce potentially significant cultural resource impacts resulting from the Project (Draft Supplemental EIR, pp. 4.2-15 — 4.2-16): GPU PEIR MM CUL-6: If the archaeological assessment did not identify archaeological resources but found the area to be highly sensitive for archaeological resources, a qualified archaeologist and a Native American monitor approved by a California Native American Tribe identified by the Native American Heritage Commission as culturally affiliated with the project area shall monitor all ground -disturbing construction and pre - construction activities in areas with previously undisturbed soil of high sensitivity. The archaeologist shall inform all construction personnel prior to construction activities of the proper procedures in the event of an archaeological discovery. The training shall be held in conjunction with the project's initial on -site safety meeting and shall explain the importance and legal basis for the protection of significant archaeological resources. The Native American monitor shall be invited to participate in this training. In the event that archaeological resources (artifacts or features) are exposed during ground -disturbing activities, construction activities in the immediate vicinity of the discovery shall be halted while the resources are evaluated for significance by an archaeologist who meets the Secretary's Standards. and This will include tribal consultation and coordination with the Native American monitor in the case of a prehistoric archaeological resource or tribal resource. If the discovery proves to be significant, the long-term disposition of any collected materials should be determined in consultation with the affiliated tribe(s), where City of Santa Ana The Village Santa Ana Specific Plan Project August 2025 CEQA Findings of Fact and Statement of Overriding Considerations 5-6
