City of Pleasanton—Villages at the Quarry Project Consistency Checklist 15183 Consistency Checklist 118 lateral spreading is low, due to the relatively flat topography and low liquefaction potential.13 The Geotechnical Report identified highly compressible existing fill deposits underlying the project site. However, the Geotechnical Report concluded that, due to the age of the fill placement, any settlement due to the existing fill is essentially complete. Because of the nature of the existing fill, the Geotechnical Report concluded that approximately 2 to 4.5 inches of potential total (long-term) settlement could be anticipated over a design life of 100 years.14 However, the Geotechnical Report includes a ground improvement program for both the southern and northern portions of the project site, which would include, as applicable, partial removal and replacement of existing soils and surcharge. Per General Plan Program 2.2, the recommendations contained in the Geotechnical Investigation regarding unstable soils are required to be implemented as part of the proposed project, which would reduce potential environmental impacts to less than significant. Therefore, development as proposed would not result in any environmental effects that are peculiar to the proposed project. The proposed project would not result in a new or more severe adverse impact that was not previously identified in the Housing Element Update FEIR. d) Expansive Soils Would the project: Be located on expansive soil, creating substantial direct or indirect risks to life or property? Summary of Housing Element Update FEIR The Housing Element Update FEIR indicated new development constructed on expansive soils could be subject to damage or become unstable when underlying soil shrinks or swells.15 The actual presence and extent of expansive soils can only be determined as part of site-specific soils and geologic reports. The Housing Element Update FEIR concluded that compliance with the CBC, applicable Municipal Code requirements, as well as goals, policies, and 13 ENGEO Incorporated (ENGEO). 2024.
