4 Environmental Analysis 4.7 Geology, Soils, and Paleontological Resources fossils could be discovered up to 10 feet, the implementation of mitigation for unanticipated fossil discovery would reduce the potential significance of any unanticipated fossil discoveries to a less- than-significant level. Through the implementation of Mitigation Measures GEO-1 through GEO-3, these improvements would not have a substantial adverse effect on any geology, soils, or paleontological resources, and no additional mitigation measures would be required. 4.7.7 Cumulative Impacts Impacts related to geology, soils, and seismicity tend to be site-specific and depend on the local geology and soil conditions. For these reasons, the geographic scope for potential cumulative impacts consists of the Project site and adjacent areas. One cumulative project, as identified in Table 2-3 in Chapter 2, Project Description, is adjacent to the Project. Additionally, the Project would be designed and constructed in accordance with the most current building code requirements, and the potential for the Project to exacerbate seismic hazards would be less than significant. State and local building regulations and standards have been established to address and reduce the potential for projects to cause or exacerbate seismic hazard impacts. All projects would be required to comply with applicable provisions of these laws and regulations. Compliance with these requirements would limit the potential for impacts to a less than significant level. The purpose of the CBC (and related local ordinances) is to regulate and control the design, construction, quality of materials, use or occupancy, location, and maintenance of all buildings and structures within its jurisdiction. Based on compliance with these requirements, the incremental impacts of the Project combined with impacts of other projects in the area would not combine to cause a significant cumulative impact related to seismic hazards. Other individual projects and this Project are required to comply with existing codes, standards, and permitting requirements (e.g., preparation of a SWPPP under the state Construction General Permit) to reduce erosion impacts. Potential Project-related impacts to soil erosion and loss of topsoil would be reduced through the implementation of the BMPs identified in the SWPPP, as required by Mitigation Measure GEO-1. Requirements in the state Construction General Permit are designed to reduce adverse cumulative effects of construction-phase erosion. Individual projects' compliance with stormwater control requirements would reduce the overall cumulative impact to a less-than-significant level. The aerial extent of cumulative impacts to paleontological resources includes the Project site and adjacent areas where Pleistocene-age deposits could be disturbed. If there were paleontological resources that extended across areas of ground disturbance of the proposed Project and cumulative projects, the projects could result in the loss of paleontological resources, a potentially significant impact. However, with implementation of Mitigation Measures GEO-2 and GEO-3, the proposed Project would have a less-than-significant impact relating to the potential loss of paleontological resources in the event of inadvertent discovery during construction. This less- than-significant impact would not be cumulatively considerable because work would be halted immediately in the event of a find, thereby minimizing the potential impact.
