3. Environmental Checklist impacted portions of the resource. The treatment plan should include provisions for analyzing the data in a regional context, timely reporting of results, proper curation of artifacts and data in an approved facility, and dissemination of the reports to local and state repositories, libraries, and interested professionals. c) Disturbance to human remains. The Project area does not show any signs of being used for burial purposes, either in recent times or in the distant past. However, if human remains are unexpectedly found during the construction of the Project, all work in the vicinity will be immediately stopped. Disturbing human remains would be considered a potentially significant impact. To address this, the following mitigation measure has been established to reduce any potential impacts to a level that is less than significant. Impact Designation: Less than Significant with Mitigation Mitigation Measure CR-2: Inadvertent Discovery of Human Remains. If human remains are discovered during construction activities, all work within 100 feet of the site must stop immediately. The Alameda County Coroner must be notified to ascertain whether an investigation into the cause of death is necessary. If the remains are determined to be Native American, the Native American Heritage Commission (NAHC) must be contacted within 24 hours. The NAHC will identify the person or persons believed to be the most likely descendant(s) of the deceased Native American. These individuals will then provide recommendations to San Leandro regarding the proper treatment of the human remains and any associated grave goods. Cumulative Impacts on Cultural Resources The scope of cumulative impacts associated with cultural resources is focused on areas nearby where the Project could disturb historical and archaeological resources, or human remains. Since the Project is not expected to impact historical structures or paleontological resources, no significant cumulative impact is anticipated in these areas. However, both this Proposed Project and other future projects in the vicinity may affect undiscovered archaeological resources or human remains during construction. The combined potential impacts of these projects could be significant regarding buried archaeological resources or human remains. Nonetheless, the application of Mitigation Measures CR-1 and CR-2, which mandate halting work for evaluation by a qualified archaeologist or the County Coroner in case of finding human remains, will minimize these impacts. Additionally, other projects undergoing CEQA review will implement similar discovery protocols. Therefore, with these mitigation measures in place, the Project's contribution to cumulative impacts on archaeological resources or human remains is deemed not considerable, leading to a less than significant impact.
