SANTA ANA REZONE PROJECT INITIAL STUDY/MITIGATED NEGATIVE DECLARATION Cultural Resources Would the project: a) Cause a substantial adverse change in the significance of a historical resource as pursuant to Section 15064.5? No impact. Results from the SCCIC indicate that no historical resources have been recorded within the project site; however, three historic built environment resources have been recorded within the 0.5-mile search radius of the project site. In addition, the pedestrian survey failed to identify any historical resources within the project site. Furthermore, a review of 29 historic aerial photographs depicting the project site from 1946 to 2022 indicate that the project site remained undeveloped. The project site does not contain any buildings, structures, or objects that could potentially qualify as historical resources under CEQA. Therefore, there would be no impact related to historical built environment resources. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5? Less than significant impact with mitigation incorporated. Results from the SCCIC indicate that there are no pre -contact archaeological resources located within the project boundaries, or the 0.5- mile radius. In addition, the pedestrian survey failed to identify any archaeological resources. While there are no known archaeological resources within the project site, it is possible that earthmoving activities associated with project construction could encounter previously undiscovered archaeological resources. Archaeological resources can include but are not limited to stone, bone, wood, or shell artifacts or features, including hearths and structural elements. Damage or destruction of these resources would be a potentially significant impact. Implementation of MM CUL-1 would ensure that this potential impact is reduced to a less than significant level. As such, the proposed project would not cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5 with the implementation of MM CUL-1. Impacts would be less than significant with mitigation incorporated. c) Disturb any human remains, including those interred outside of formal cemeteries? Less than significant impact with mitigation incorporated. As noted above, results from the SCCIC and pedestrian survey failed to locate or identify any human remains and/or cemeteries. The potential for the disturbance of any human remains is considered low. While it is unlikely that the presence of human remains exists within or near the project site, there is always the possibility that subsurface construction activities associated with the proposed project, such as grading or trenching, could potentially damage or destroy previously undiscovered human remains. 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. MM CUL-2 further specifies the procedures to follow in the event human remains are uncovered.
