The Warner Redhill Mixed -Use Project CEQA Findings of Fact not identified previously. Thus, with implementation of existing regulations and Mitigation Measure HAZ-1, impacts related to upset or accident conditions involving the release of hazardous materials into the environment would be less than significant. Mitigation Measures: Mitigation Measure HAZ-1: Soil Management Plan (SMP). As listed previously. H. Tribal Cultural Resources Impact Finding: The Project would not cause a substantial adverse change in the significance of a resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, that considers the significance of the resource to a California Native American tribe (Draft El at p. 5.15-6). Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant environmental effect identified in the Draft EIR. Facts in Support of Findings: The Project site has been heavily disturbed to substantial depths. The proposed Project involves excavation; however, no substantial evidence exists that TCRs are present in the Project site. Although, no TCRs have been identified, during the SB 18/AB 52 consultation, the Gabrieleno Band of Mission Indians — Kizh Nation stated that the Project lies within its ancestral tribal territory within a potentially sensitive area. Therefore, to avoid potential adverse effects to tribal cultural resources, Mitigation Measure TCR-1 has been included to provide for Native American resource sensitivity training, monitoring, and to prescribe activities should any inadvertent discoveries of tribal cultural resources be unearthed by Project construction activities. Additionally, California Health and Safety Code, Section 7050.5 requires that if human remains are discovered in the Project site, disturbance of the site shall halt and remain halted until the coroner has conducted an investigation. If the coroner determines that the remains are those of a Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission. Therefore, with implementation of Mitigation Measure TCR-1 and the existing regulations, impacts to TCRs would be less than significant. Mitigation Measures: Mitigation Measure TCR-1: Native American Monitoring. Prior to the issuance of any permits for initial site clearing (such as pavement removal, grubbing, tree removals) or issuance of permits allowing ground -disturbing activities that cause excavation to depths greater than artificial fill (including as boring, grading, excavation, drilling, potholing or auguring, and trenching), the City of Santa Ana shall ensure that the project applicant/developer retain qualified Native American Monitor(s). The monitor(s) shall be approved by the tribal representatives of the Gabrieleno Band of Mission Indians - Kizh Nation and be present on -site during initial site clearing and construction that involves ground disturbing activities that cause excavation to depths greater than artificial fill identified herein. The monitor shall conduct a Native American Indian Sensitivity Training for construction personnel. The training session includes a handout and focus on how to identify Native American resources encountered during earthmoving activities and the procedures followed if resources are discovered. The Native American monitor(s) shall complete monitoring logs on a daily basis, providing descriptions of the daily activities, including construction activities, locations, City of Santa Ana 45 May 2020
