City of Pleasanton—Hidden Canyon Residences and Preserve Cultural Resources and Tribal Cultural Resources Draft EIR 3.4-26 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec03-04 Cultural-Tribal Cultural Resources.docx Construction could result in the inadvertent exposure of buried archaeological resources. As such, Mitigation Measure (MM) CUL-2 includes provisions for the inadvertent discovery of archaeological resources, would reduce potential impacts to archaeological resources that may be discovered during project construction to a less than significant level. Operation Impacts related to a project’s potential to cause a substantial adverse change in the significance of an archaeological resource are limited to construction impacts. No respective direct or indirect operational impacts related to archaeological resources would occur. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures MM CUL-2 The project proponent shall note on any plans that require ground-disturbing excavation that there is a potential for exposing buried cultural resources including prehistoric Native American burials. The project proponent shall retain a Professional Archaeologist on an “on-call” basis during ground-disturbing construction for the project to review, identify and evaluate cultural resources that may be inadvertently exposed during construction. The Archaeologist shall review and evaluate any discoveries to determine whether they are historical resource(s) and/or unique archaeological resources under CEQA. If any prehistoric or historic artifacts, or other indication of cultural resources are found once the project construction is underway, all work shall stop within 20- meters (66 feet) of the find. A qualified Archaeologist shall be consulted for an immediate evaluation of the find prior to resuming groundbreaking construction activities within 20 meters of the find. If the find is determined to be an important archaeological resource, the resource shall be either avoided, if feasible, or recovered consistent with the requirements of the California Environmental Quality Act (CEQA) Guidelines. Level of Significance After Mitigation Less than significant impact. Human Remains Impact CUL-3: The proposed project could disturb human remains, including those interred outside of formal cemeteries. Impact Analysis Construction While no formal cemeteries are known to be in the project vicinity, there is one pre-contact resource that has been recorded within a 0.5-mile radius of the project site that is known to contain human
