Refer to <br />Division of Mines and Geology Special <br />Publication 42. <br />ii) Strong seismic ground shaking? <br />X <br />iii) Seismic -related ground failure, <br />including liquefaction? <br />X <br />iv) Landslides? <br />X <br />b) Result in substantial soil erosion or the loss <br />of topsoil? <br />X <br />c) Be located on a geologic unit or soil that is <br />unstable, or that would become unstable as <br />a result of the project, and potentially result <br />X <br />in on- or off -site landslide, lateral spreading, <br />subsidence, liquefaction or collapse? <br />d) Be located on expansive soil, as defined in <br />Table 18-1-B of the Uniform Building Code <br />(2013), creating direct or indirect substantial <br />X <br />risks to life or property? <br />e) Have soils incapable of adequately <br />supporting the use of septic tanks or <br />alternative waste water disposal systems <br />X <br />where sewers are not available for the <br />disposal of wastewater? <br />f) Directly or indirectly destroy a unique <br />paleontological resource or site or unique <br />X <br />geologic feature? <br />No known fault traces are located in the City of Santa Ana POC 2020). The Project Site is not located within <br />a zone of potential liquefaction nor landslides POC 1998). Like most of the surrounding area, the Project Site <br />is flat and developed and is not subject to landslides or substantial erosion. <br />Page 46 PlaceWorks <br />
