Administrative Draft Environmental Impact Report <br /> Gill Medical Center Project <br /> Based on the paleontological records search the project site is within the Modesto Formation.The <br /> Modesto Formation has a high paleontological sensitivity and a low-to-moderate paleontological <br /> potential for significant paleontological resources. Therefore Project development could destroy unique <br /> paleontological resources which is a significant impact. With implementation of mitigation measures 4.9- <br /> 5a and 4.9-5b, this impact would be less than significant with mitigation incorporated. <br /> The heavily disturbed surface of the project site precludes a preconstruction paleontological survey. <br /> Therefore paleontological training of and monitoring by construction personnel of construction-related <br /> earth-disturbing activities that will impact previously undisturbed sediments is the preferred mitigation <br /> approach as discussed below. <br /> Mitigation Measures <br /> The following mitigation measures apply to impact 4.9-5. <br /> 4.9-5a: Worker Awareness Training <br /> A professional paleontologist shall provide the construction crew with a pre-construction <br /> orientation and training on the significant paleontological resources that may be <br /> encountered and the appropriate procedures to follow should any be unearthed. <br /> Timing/Implementation: Prior to construction <br /> Monitoring/Enforcement: County of San Joaquin Planning/Development Services Division <br /> 4.9-5b: Unanticipated Discovery of Paleontological Resources. <br /> If subsurface deposits believed to be paleontological in origin are discovered during <br /> construction, all work shall halt within a 50-foot radius of the find until a professional <br /> paleontologist has assessed it and, if deemed significant, salvaged the fossil(s) in a timely <br /> manner.A plan for monitoring and fossil recovery must be completed and implemented <br /> before ground-disturbing activities can recommence in the area of the fossil find to allow <br /> for the recovery of the find. Salvaged fossils shall be deposited in an appropriate <br /> repository, such as the UCMP, where they will be properly curated and made available for <br /> future research. <br /> Timing/Implementation: During construction <br /> Monitoring/Enforcement.- County of San Joaquin Planning/Development Services Division <br /> 4.9.4 Cumulative Impacts <br /> The geologic area considered for the analysis of cumulative impacts related to geologic resources and <br /> hazards is within the immediate project vicinity.Temporary construction activities associated with the <br /> Proposed Project would involve construction activities such as trenching, excavation, and backfilling. <br /> Geology and Soils 4.9-11 October 2021 <br />
