>r �(tial Study—LID Annexation development site as may be requested by the Building Official. The geologic investigation shall be prepared by a state-certified engineering geologist and shall recommend further corrective action likely to prevent structural damage to dwelling units. Prior to the issuance of a building permit,any recommended action approved by the Building Official shall be incorporated into site preparation and the construction of each dwelling. 2.6.2 Geology and Soils—Impacts Potentially Less Than Less Than No Impact Significant Significant Significant Impact with Mitigation Impact Incorporation VI. GEOLOGY AND SOILS--Would the project: a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury,or death involving: i) Rupture of a known earthquake fault, as delineated on the ❑ ❑ ❑ most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. ii)Strong seismic ground shaking? ❑ ❑ ❑ 0 iii)Seismic-related ground failure,including liquefaction? ❑ ❑ ❑ 0 iv)Landslides? ❑ ❑ ❑ N b)Result in substantial soil erosion or the loss of topsoil? ❑ ❑ ❑ 0 c)Be located on strata or soil that is unstable, or that would become ❑ ❑ ❑ unstable as a result of the project,and potentially result in on-or off- site landslide, lateral spreading,subsidence,liquefaction or collapse? d) Be located on expansive soil, as defined in Table 18-1-B of the ❑ ❑ ❑ N Uniform Building Code,creating substantial risks to life or property? e) Have soils incapable of adequately supporting the use of septic ❑ ❑ ❑ 0 tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? Geology and soils issues associated with proposed development were fully analyzed in the River Islands EIR. These issues included concerns related to soil erosion,trench collapse during construction, seismic hazards and soil shrink-swell concerns. The EIR and adopted MMRP included mitigation measures that would reduce all of these impacts to less than significance. The proposed Project would be located on a similar site in the vicinity of the existing approved sites under similar soil and geologic conditions. The proposed project would involve similar activities and no new or 37
