EXHIBIT A groundwater levels at 110 feet below the ground surface and 143 feet below the ground surface. In addition, borings on the Project site in 2017 identified that soils consist of silty fine to medium sands with local layers of fine to coarse sands with gravel size rock and some larger rock fragments, which are not the uniform fine-grained sand that typically liquefies. In addition, the Geotechnical Engineering Investigation (Geo 2017) prepared for the Project site conducted liquefaction analysis and determined that thin layers of onsite soils have the potential for liquefaction; however, these soils are confined by less permeable soils that would prevent the manifestation of liquefaction. Thus, because the groundwater level is far below 50 feet below the ground surface and soils are not uniformly graded fine-grained, the potential for liquefaction and related lateral spreading or ground failure to occur on the Project site is low. In addition, as described above, the proposed Project would be required to be constructed in compliance with the CBC and the City's Municipal Code, as detailed in the Geotechnical Engineering Investigation (Geo 2017) prepared for the Project site, which would be verified through the City's permitting process. (Initial Study, pp. 30-31) For the aforementioned reasons, the Project would result in a less than significant impact related to liquefaction, lateral spreading, and ground failure. (Initial Study, pp. 30-31) 9.6.1.4 Exposure to Potential Risk of Loss, Injury, or Death — Landslides Threshold: Would the Project expose people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving landslides? Finding: No impact. (DEIR, p. 2-6; Initial Study, p. 31) Facts in Support of Finding: Landslides and other slope failures are secondary seismic effects that are common during or soon after earthquakes. Areas that are most susceptible to earthquake induced landslides are steep slopes underlain by loose, weak soils, and areas on or adjacent to existing landslide deposits. As described above, the Project site is located in a seismically active region subject to strong ground shaking. However, the Project site is not located within or adjacent to an earthquake -induced landslide area. (Initial Study, p. 31.) In addition, the Project site is located in a flat developed urban area that does not contain or is adjacent to large slopes, and the Project would not generate large slopes. Furthermore, as stated in the Geotechnical Engineering Investigation prepared for the Project site, the Project site is not at risk for earthquake induced landslides. For the foregoing reasons, implementation of the Project would not expose people or structures to substantial adverse effects involving landslides, and impacts related to landslides would not occur. (Initial Study, p. 31.) 9.6.2 Soil Erosion Threshold: Would the Project result in substantial soil erosion or the loss of topsoil? Finding: Less than significant impact. (DEIR, p. 2-6; Initial Study, pp. 31-32.) Facts in Support of Finding: The Project site is largely impervious, as it is generally covered by pavement or the building structure. However, small areas of landscaping exist within the parking area, along the site boundary, and adjacent to the existing building. The Project would redevelop the site for multi -family residential uses, which would include areas of landscaping that would surround the proposed structures and be located along the site boundary, similar to the areas of landscaping that currently exist. The new paved areas and landscaping from the Project would not result in soil erosion or the loss of topsoil. In addition, Section 18-156 of the City of Santa Ana Municipal Code states that all significant Resolution No. Certification of the Magnolia at the Park EIR 75E-66 Page 28 of 71
