City of Pleasanton—Hidden Canyon Residences and Preserve <br />Draft EIR Geology, Soils, and Seismicity <br /> <br /> <br />FirstCarbon Solutions 3.6-21 <br />https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec03-06 Geology.docx <br />Priolo Earthquake Fault Zone, the site-specific soils and/or geotechnical report shall <br />address the impacts of seismic ground shaking on proposed structures, infrastructure, <br />and ground stability. <br />Program 2.2 Design and construct all structures to address potential seismic and geologic hazard <br />conditions according to the California Building Standards Code (CBC) standards or <br />more stringent standards. All structures and facilities not addressed by the CBC shall <br />be designed and constructed to mitigate potential seismic and geologic hazards as <br />recommended by site-specific soils, geologic, and/or geotechnical engineering <br />studies. <br />Program 2.5 Require technical review and analysis of soils, geologic, and geotechnical studies by a <br />qualified consulting engineering geologist reporting to the City of Pleasanton. <br />Incorporate the recommendations of the City’s consulting engineer into the project <br />design. <br />Program 2.6 Require professional inspection of foundations, piers, excavation, earthwork, and <br />other aspects of site development during construction. Ensure that all mitigations <br />recommended by the City’s consulting engineer are incorporated into the project <br />construction. <br />Policy 3 Require post-earthquake construction, if needed, to conform to all City codes and <br />ordinances. <br />Program 3.1 Require building permits and enforce all current building requirements and codes for <br />post-earthquake construction. <br />Goal 2 Minimize the risks to lives and property, and minimize potential liability to the City, <br />due to geologic hazards within the Plan Area. <br />Policy 5 Investigate the potential for geologic hazards as part of the development review <br />process, and maintain this information for the public record. <br />Program 5.1 Require site-specific soils studies for all new development prior to the issuance of <br />building permits and prior to the approval of final improvement plans. Where there is <br />risk of geologic hazards, the soil study should address seismic shaking, lateral <br />spreading, differential settlement, lurch cracking, liquefaction, erosion, and expansive <br />soils. <br />Program 5.2 Require site-specific geologic and/or geotechnical engineering studies prior to <br />development approval where there is risk of the following geologic hazards: surface <br />fault rupture, bank failures, rock falls, landslides, and for areas with slopes equal to or <br />greater than 20 percent. <br />Program 5.3 Require measures to mitigate potential geologic safety hazards during adverse <br />conditions such as saturated soils and ground shaking, and during grading of the site
