The Warner Redhill Mixed -Use Project CEQA Findings of Fact immediate vicinity of the construction equipment. Also, the short-term construction -related odors would cease upon the drying or hardening of the odor -producing materials. In addition, all Project -generated solid waste would be stored in covered containers and removed at regular intervals in compliance with solid waste regulations and would not generate objectionable odors. Therefore, impacts associated with other operation- and construction - generated emissions, such as odors, would be less than significant. C. Cultural Resources Impact Finding: The Project would not cause a substantial adverse change in the significance of a historical resource pursuant to CEQA Guidelines Section 15064.5 (Draft EIR at p. 5.3-7). Facts in Support of Findings: The Project site does not contain any historic resources. As described in the Phase I Environmental Site Assessment that was prepared for the Project site (Phase 1 2018) (Appendix D of the Draft EIR), aerial photographs between 1938 and 1977 show the site being used for agriculture or being vacant. The existing industrial buildings was constructed in the early 1980s, which are not more than 39 years old and are not historic resources. The industrial buildings were previously used by Ricoh Electronics Inc. for imaging and electronics manufacturing. No historically important activities previously occurred within the existing buildings. Overall, the site does not include any historic resources and implementation of the proposed Project would not impact a historic resource. In addition, the Project site is not adjacent to any historic structures. Areas surrounding the site consist of modern office buildings, business park buildings, modern public service facilities, and vacant land that is proposed for new development. Therefore, redevelopment of the Project site would not result in an indirect effect to any off -site historic resources. Overall, no impacts related to historic resources would occur from implementation of the proposed Project. Impact Finding: The Project would not cause a substantial adverse change in the significance of an archaeological resource pursuant to CEQA Guidelines Section 15064.5. (Draft EIR at p. 5.3-7). Facts in Support of Findings: The site has a long history of ground disturbance from previous agricultural uses and development, as detailed in the Geotechnical Report (Appendix C of the Draft EIR) describes that artificial fill was observed in field explorations up to 7.5 feet below existing grade and previous excavation and recompaction ranged from 5 feet to 13 feet for development of the existing buildings and removal of underground storage tanks. It is likely that the site disturbance included the undeveloped portion of the site at the corner of Red Hill and Warner Avenue. The extensive previous excavation, recompaction, and fill soils onsite have limited the potential of the site to contain archaeological resources. Also, as described in the Draft EIR Section 3.0, Project Description, the proposed Project would excavate onsite soils to a minimum of 5 feet below the bottom of the building foundations and 5 feet beyond the building perimeters. The soils would be reconditioned and recompacted as engineered fill to support the proposed building structures. The depth of the excavation is within the previously disturbed soil depths, which further reduces the potential of the Project to result in impacts related to archaeological resources.
