Expose people or structures to potential substantial adverse <br /> effects, including the risk of loss, injury, or death involving: <br /> (1) Rupture of a known earthquake fault, as delineated on the <br /> most recent Alquist-Priolo Earthquake Fault Zoning Map issued 4 <br /> by the State Geologist for the area or based on other <br /> substantial evidence of a known fault? Refer to Division of <br /> Mines and Geology Special Publication 42. <br /> (2) Strong seismic ground shaking? <br /> (3) Seismic-related ground failure, including liquefaction? <br /> J <br /> (4) Landslides? <br /> b.

Be located on expansive soil, as defined in Table 18-1-B of the <br /> Uniform Building Code (1998), creating substantial risks to life or <br /> property? <br /> e. Have soils incapable of adequately supporting the use of septic <br /> tanks or alternative wastewater disposal systems in areas where <br /> sewers are not available for the disposal of wastewater? <br /> NARRATIVE DISCUSSION <br /> Environmental Setting <br /> The project site is located in an upland valley portion of the San Joaquin Valley on inter- <br /> bedded clay, silt, sand, and gravel deposits. The topography of the project site is <br /> essentially flat, as it has been developed for urban uses. According to information from <br /> the Natural Resources Conservation Service, the soil on the project area consists of <br /> Jacktone - Urban Land complex. Jacktone - Urban Land complex is made up of 50% <br /> Jacktone Clay and 35% urban land. The soil Is moderately deep to a hardpan and <br /> somewhat poorly drained. Permeability in the Jacktone portion of the soil is slow, runoff <br /> 121339/ST011 R226 3-29 October 14, 2011 <br /> Copyright 2011 Kleinfelder <br />
