Less than significant impact with mitigation incorporated. Records search results from the NWIC indicate that no archaeological resources have been recorded within a 0.5-mile radius of the project site. Furthermore, the project site is entirely hardscaped indicating that subsurface soils are likely highly disturbed, and an intensive pedestrian survey of the project site conducted by FCS on February 5, 2021, failed to identify any indications of archaeological resources within the project site. The project site is therefore considered to have low sensitivity for undiscovered archaeological resources. While the records search and survey data indicate the likelihood of encountering archaeological resources during project construction is low, there is always a possibility that subsurface excavation may encounter previously undiscovered prehistoric archaeological resources. Such resources could consist of but are not limited to stone, bone, wood, or shell artifacts or features, including hearths and structural elements. Accordingly, this is a potentially significant impact. Implementation of MM CUL-1 would ensure that this potential impact is reduced to a less-than-significant level. c) Disturb any human remains, including those interred outside of formal cemeteries? Less than significant impact with mitigation incorporated. There are no records of historic cemeteries, Native American burial sites, or other evidence that human remains may exist within the project area. However, there is always the possibility that subsurface construction activities associated with the proposed project, such as trenching and grading, could potentially damage or destroy previously undiscovered human remains. Accordingly, this is a potentially significant impact. In the event of the accidental discovery or recognition of any human remains, CEQA Guidelines Section 15064.5, Health and Safety Code Section 7050.5, and Public Resources Code Sections 5097.94 and 5097.98 must be followed. In the unlikely event human remains are discovered, implementation of MM CUL-2 would reduce this potential impact to a less than significant level. Tribal Cultural Resources Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: d) Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k), or Less than significant impact with mitigation incorporated. A review of the CRHR, local registers of historic resources, a records search conducted at the NWIC, failed to identify any listed or eligible TCRs that may be adversely affected by the proposed project. An NAHC sacred lands file search, however, indicated that the project was positive for TCRs within the area, and recommended the Muwekma Ohlone Indian Tribe be contacted for additional information. FCS contacted all 10 tribal representatives and received two requests for additional information, which were provided. No
