City of Pleasanton—Merritt Property Project <br />Consistency Checklist 15183 Consistency Checklist <br /> <br /> <br />104 <br />The Housing Element Update FEIR concluded that compliance with CBC and <br />applicable Municipal Code requirements, as well as goals, policies, and <br />programs included as part of the General Plan, would ensure that potential <br />impacts associated with development on unstable geologic units or unstable <br />soils would be less than significant. <br />Proposed Project Analysis and Conclusion <br />The Geotechnical Investigation (Appendix E) found that the blow counts for <br />material encountered above and below groundwater were high. Blow <br />counts are derived from a standard penetration test, where a 140-pound <br />weight is dropped, and the number of blows to advance the point 1 foot is <br />counted. Loose or soft soils generally show blow counts of less than 10. <br />Therefore, the Geotechnical Investigation determined that the potential for <br />liquefaction at the project site is very low. <br />Furthermore, the project site generally consists of competent soils and <br />bedrock, and the Geotechnical Investigation did not identify areas of <br />instability. Therefore, impacts related to landsliding are considered relatively <br />low. <br />Per General Plan Program 2.2, the recommendations contained in the <br />Geotechnical Investigation regarding unstable soils are required to be <br />implemented as part of the proposed project. Environmental effects would <br />be avoided by the imposition of uniformly applied development policies or <br />standards. Therefore, development of the site as proposed would not result in <br />any environmental effects that are peculiar to the proposed project. The <br />proposed project would not result in a new or more severe adverse impact <br />that was not previously identified in the Housing Element Update FEIR. <br />b) Soil Erosion or Topsoil Loss <br />Would the project: Result in substantial soil erosion or the loss of topsoil? <br />Summary of Housing Element Update FEIR <br />The Housing Element Update FEIR indicated that development consistent <br />with the Housing Element Update would involve construction activities such <br />as stockpiling, grading, excavation, paving, and other earth-disturbing <br />activities that could result in soil erosion or the loss of topsoil. Soil erosion is <br />dependent on individual site locations and conditions on-site during <br />construction.
