Environmental Impacts of the Proposed Changes to the Original Project Addendum to the City of Pleasanton Downtown Specific Plan Final Environmental Impact Report 39 Effects and Mitigation Measures No new or substantially more severe significant effects would occur to greenhouse gas emissions and energy compared to those identified in the Final EIR, and no new mitigation measures are necessary. Conclusion Impacts related to greenhouse gas emissions would be less than significant, and would be reduced compared to the significant and unavoidable impacts identified in the Final EIR. Impacts related to energy would be less than significant, similar to the Final EIR. No significant new or substantially increased greenhouse gas emissions or energy impacts would occur compared to those identified in the Final EIR. 5.6 Geology and Seismicity Impacts Identified in the Certified Final EIR The Final EIR determined that although the DSP area does not overlie a known earthquake fault, the DSP area is within a seismically active region and would be subject to strong ground shaking, liquefaction, and lateral spreading. However, development in the DSP area would be subject to several existing state and local regulations that require site-specific geological investigations and design elements to minimize susceptibility to seismic events. Development would be required to comply with Chapter 17.12.050 of PMC, which requires preparation of geotechnical investigation reports to characterize existing geologic hazards and risks. Additionally, several existing General Plan policies would restrict development in hazardous areas, sloped lots, and earthquake fault zones. Due to the generally flat topography of the DSP area, there is a low probability of landslides. Therefore, the Final EIR concludes that implementation of the DSP would not expose people or structures to risk of loss, injury, or death associated with earthquake fault zones, strong seismic ground shaking, liquefaction, or landslides, and impacts would be less than significant. Development within the DSP area would be required to connect to existing wastewater infrastructure and would not utilize alternative wastewater disposal systems or septic tanks. The Final EIR determined that the DSP would have no impact related to soils incapable of adequately supporting the use of septic tanks or other wastewater disposal systems. Impacts of the Barone’s Project The following analysis incorporates information from the Geotechnical Investigation prepared for the project by Geo-Logic Associates in June 2022. The Geotechnical Investigation is included as Appendix D. Section 1803.1.1.3 of the California Building Code (CBC) states that the building department of each locality (in this case the Pleasanton Building Division) must approve the soil investigation if it determines that the recommended action is likely to prevent structural damage in each dwelling. Further, as a condition of the building permit, the approved recommended action must be incorporated in the construction of each dwelling. Therefore, pursuant to the PMC and the CBC, the recommendations included in the Geotechnical Investigation (Appendix D) would be incorporated into the design of the project and verified by the City prior to issuance of a building permit.
