<br />Pleasanton Gateway Environmental Checklist <br /> <br />6. GEOLOGY AND SOILS <br /> <br />Environmental Setting <br /> <br />The subject site lies within the Alquist-Priolo Fault Zone3, Seismic Zone 8. The approval of a project by <br />a city or county must be in accordance with policies and criteria established by the State Mining and <br />Geology Board. Cities and counties shall require, prior to the approval of a project, a geologic report <br />defining and delineating any hazard of surface fault rupture. If the city or county finds that no undue <br />hazard of that kind exists, the geologic report on the hazard may be waived, with the approval of the <br />State Geologist. After a report has been approved or a waiver granted, subsequent geologic reports shall <br />not be required, provided that new geologic data warranting further investigations is not recorded. <br /> <br />Standards of Significance <br /> <br />For purposes of this environmental document, an impact is considered significant if the proposed project <br />would: <br /> <br />· Result in a project being built that will either introduce geologic, soils, or seismic hazard by al- <br />lowing the construction of the project on such a site without protection against those hazards, <br /> <br /> Less Than <br /> Potentially Significant I.css Than <br /> Significant With Mitigation Significant No <br />Issues Impact Incorporated Impact Impact <br />Geolo2V and Soils <br />Would the project: <br />a) Expose people or structures to potential substantial ad- O 0 lliJ 0 <br /> verse effects, including the risk of loss, injury, or death <br /> involving: <br /> i) Rupture of a known earthquake fault, as delineated 0 0 [E] 0 <br /> on the most recent Alquist-Priolo Earthquake Fault <br /> Zoning Map issued by the State Geologist for the <br /> area or based on other substantial evidence of a <br /> known fault?
