photographs, suggests that intact cultural resources are unlikely to exist in the Project area. Historically an intertidal marsh, aerial photos from 1946 and 1958 depict the present pond area as submerged, indicating it is now primarily disturbed fill sediment. Based on the results of correspondence with the NAHC and the NWIC records search, no known tribal cultural resources listed or determined eligible for listing in the California Register or included in a local register of historical resources as defined in PRC Section 5020.1(k), pursuant to PRC Section 21074(a)(1), would be impacted by the Project. However, if any previously unrecorded archaeological resource were identified during ground - disturbing construction activities and were found to qualify as a tribal cultural resource pursuant to PRC Section 21074(a)(1) (determined to be eligible for listing in the California Register or in a local register of historical resources), any impacts to the resource resulting from the Project could be potentially significant. Any potential significant impacts would be reduced to a less than significant level by implementing Mitigation Measure CR-1(Inadvertent Discovery of Cultural Resources; refer to the Section 3.5, Cultural Resources) and CR-2 (Inadvertent Discovery of Human Remains). impact ❑esi nation: Less than Significant with Mitigation b) Impacts to tribal resources. Based on the results of correspondence with the NAHC and the NWIC records search, the City did not determine any resource that could potentially be affected by the Project to be a tribal cultural resource significant pursuant to criteria set forth in PRC Section 5024.1(c). Therefore, the Project is not anticipated to affect any such resources. However, if any previously unrecorded archaeological resource were identified during project implementation, particularly ground -disturbing construction activities, and were found to qualify as a tribal cultural resource pursuant to PRC Section 21074(a)(2) (determined by the lead agency to be significant pursuant to criteria set forth in PRC Section 5024.1[c]), any impacts to the resource resulting from the Project could be potentially significant. Any potential significant impacts would be reduced to a less than significant level by implementing Mitigation Measure CR-1(Inadvertent Discovery of Cultural Resources; refer to the Section 3.5, Cultural Resources) and CR-2 (Inadvertent Discovery of Human Remains). Impact Designation: Less than Significant with Mitigation Cumulative Impacts on Tribal Resources The geographic scope for cumulative effects on tribal cultural resources includes the immediate vicinity of locations where the Project could cause disturbance to known tribal cultural resources. Since the Project is not anticipated to impact known tribal cultural resources, there is no expected cumulative impact in this regard. However, it is possible that the Proposed Project and other cumulative projects in the vicinity might impact previously undiscovered archaeological resources, including human remains outside formal cemeteries, during ground -disturbing activities. These resources could be considered tribal cultural resources. To address this, Mitigation Measures CR-1 and CR-2 have been established. These measures mandate halting work near any discovered resources until they are assessed by a Secretary of the Interior -qualified archaeologist and, in the case of human remains, notifying the County Coroner.
