A response was received on December 22, 2020, indicating that the Sacred Lands File search was positive for Native American Tribal Cultural Resources (TCRs) within the area, and recommended the Muwekma Ohlone Indian Tribe be contacted for additional information. The NAHC also provided a list of nine additional tribal representatives available for consultation. To ensure that all Native American knowledge and concerns over potential TCRs that may be affected by the proposed project are addressed, a letter containing project information requesting any additional information was sent to all 10 tribal representatives on January 4, 2021. A response was received from the Indian Canyon Mutsun Band of Costanoan Ohlone People on January 4, 2021, requesting additional information about any recorded archaeological resources in the area. A similar response requesting additional information was received from the Confederated Villages of Lisjan Tribe on February 3, 2021. FCS provided the requested information to both tribes on February 19, 2021. On March 16, 2021, the City of Pleasanton sent letters containing project information and an invitation to consult on the project to Tribal representatives pursuant to AB-52. The same day, the City received a response from the Indian Canyon Band of Costanoan Ohlone People, expressing concern that the project’s Area of Potential Effect (APE) may be in close proximity to a potentially eligible cultural site. The tribe recommended that a Native American monitor and an archaeologist be present on-site at all times in order to minimize potential effects on the cultural site and mitigate inadvertent issues. No additional responses have been received to date. NAHC correspondence and copies of NAHC letters can be found in Appendix C-3. Cultural Resources Would the project: a) Cause a substantial adverse change in the significance of a historical resource as pursuant to Section 15064.5? Less than significant impact with mitigation incorporated. The results of the NWIC records search show that only one potentially historic resource has been recorded within a 0.5-mile radius of the project site, and the resource is not located within the site itself, nor are any other buildings or structures of potential historic significance. For these reasons, the potential for the proposed project to have an adverse effect on historic resources is considered low. While unlikely, subsurface construction activities always have the potential to damage or destroy previously undiscovered historic resources. Historic resources can include wood, stone, foundations, and other structural remains; debris-filled wells or privies; and deposits of wood, glass, ceramics, and other refuse. Accordingly, implementation of MM CUL-1 will be required to reduce potential impacts to historic resources that may be discovered during project construction. With the incorporation of mitigation, impacts associated with historic resources would be less than significant.
