Project plans, <br />Prior to issuance of <br />City of Santa Ana Building <br />grading specifications, and construction permitting shall detail that <br />grading permits <br />Safety Division <br />paleontological resources monitoring shall be required for excavations below <br />20 feet below ground surface (bgs). Paleontological monitoring shall be <br />During ground -disturbing <br />conducted by a monitor who meets the professional criteria established by <br />activities at 20 feet bgs. <br />the Society of Vertebrate Paleontology working under the direct supervision <br />of the Qualified Paleontologist. Monitoring can be reduced, or ceased <br />entirely, if determined adequate by the Qualified Paleontologist. <br />Recommendations for reduction or cessation of monitoring will be based on a <br />more accurate understanding of the lithologic character and age of the <br />sediments exposed during excavation. If deeper excavations continue to <br />encounter younger, Holocene alluvium, monitoring shall be reduced from full- <br />time to part-time monitoring or weekly inspections. If the Qualified <br />Paleontologist determines, based on the Iithologic character of the sediments, <br />that there is very little likelihood of impacting Pleistocene marine sediments, <br />paleontological monitoring shall cease entirely. <br />The paleontological monitor shall collect any identifiable fossils encountered <br />during the excavations. If onsite personnel discover potential fossils during <br />excavations when a paleontological monitor is not present, they shall cease <br />excavation within 50 feet of the discovery and contact the Qualified <br />Paleontologist. Construction activities may resume after the discovery is <br />assessed by the Qualified Paleontologist and appropriate treatment <br />measures have been implemented. <br />Mitigation Measure PALEO-4: Paleontological Resources Treatment and <br />Inclusion in Project plans, <br />City of Santa Ana Building <br />Disposition. Project plans, grading specifications, and construction permitting <br />grading specifications, <br />Safety Division <br />shall require that significant fossils be prepared to the point of identification <br />and construction <br />and cataloged. Significant fossils shall be curated at a public, non-profit <br />permitting prior to <br />institution with a research interest in the material and with retrievable storage, <br />issuance of grading <br />such as the Natural History Museum of Los Angeles County, if such an institution <br />permits <br />agrees to accept the fossils. If no institution accepts the fossil collection, then <br />the fossils may be donated to a local museum, historical society, school, or <br />Upon completion of <br />other institution for educational purposes. Accompanying notes, reports, maps, <br />monitoring <br />and photographs shall also be filed with the final repository. <br />City of Santa Ana 16 <br />Final Supplemental EIR <br />August 2024 <br />
