City of Pleasanton–Spotorno Ranch Reduced Development Project Environmental Checklist Initial Study/Consistency Checklist 88 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480021/Consistency Checklist/21480021 Spotorno Ranch Consistency Checklist ScreenCheck.docx having yielded mortars, pestles, and arrowheads, and is likely a significant habitation site. While the site is not located within the project boundary or in close enough proximity to potentially extend into the project area, its presence in the vicinity indicates a higher probability for undiscovered buried archaeological deposits within the project area, and coupled with poor soil visibility during both surveys, increases the potential for undiscovered resources to be encountered during project construction. Such resources could consist of but are not limited to stone, bone, wood, or shell artifacts or features, including hearths and structural elements. In addition to MM K2, the City of Pleasanton’s General Plan Policy 5 includes the following programs to protect undiscovered resources: Program 5.1 When reviewing applications for development projects, use information regarding known archaeological finds in the Planning Area to determine whether an archaeological study, construction monitoring or other mitigations are appropriate. Require that archaeological studies meet the requirements of the California Environmental Quality Act (CEQA) Guidelines Section 15064.5 in identifying mitigation measures if an archaeological site is encountered. Include provisions for the interpretation of cultural resources. Consult with the California Archaeological Inventory, Northwest Information Center, as necessary. Program 5.3 Continue to include a standard condition of project approval to require the cessation of all construction and grading activities within the vicinity of any discovered prehistoric or historic artifacts, or other indications of cultural resources, until any such find is evaluated by a qualified professional Archaeologist, and appropriate mitigation is approved by the City. In compliance with Program 5.1, FCS conducted an archaeological survey of the project site. On the basis of this survey, FCS recommends that MM K2 be refined to require monitoring of initial grading activities. This enhancement would be included as a condition of approval , and would be shown on the grading plan. c) Human Remains Would the project: Disturb any human remains, including those interred outside of formal cemeteries? The 1998 HVSP FEIR determined that buried human remains could potentially be discovered during construction. According to the 1998 HVSP FEIR, if human remains are discovered during construction, the project would comply with Sections 7505.5(b) of the California Health and Safety Code, which requires the County Coroner to be responsible for contacting the Native American Heritage Commission (NAHC) within 24 hours; and Public Resources Code Section 5097.98 and Section 5097.99, which call for, “protection of Native American human burials and skeletal remains from vandalism and inadvertent destruction.” The 1998 HVSP FEIR recommended construction personnel on the project be instructed as to the potential for discovery of human remains, and the need for proper and timely reporting of such finds, and the consequences of failure thereof.
