City of San Leandro <br />2824 Halcyon Drive Residential Project <br /> <br />40 <br />Action CD-1.12.A: Archaeological Site Inventory <br />Maintain Standard Conditions of Approval for new development which require consultation <br />with a professional archaeologist in the event that any subsurface paleontological, <br />prehistoric, archaeological, or tribal cultural resource remains are discovered during any <br />construction or preconstruction activities on a development site. This includes consultation <br />with Native American organizations prior to continued site work in the event such remains <br />are discovered. <br />Policy CD-2.2: Planning and Building Decisions <br />Ensure that day-today planning and building activities, including the issuance of building <br />permits, demolition permits, zoning approvals, site plan approvals, and use permits, are <br />consistent with and further the achievement of local historic preservation goals. The City's <br />zoning and building codes should support the reuse and restoration of historic buildings. <br />Project-Specific Impacts <br />FSC prepared a Cultural Resources Due Diligence Assessment in May 2021 (included as Appendix <br />CRS). The Due Diligence Assessment sources include updated record searches of the Northwest <br />Information Center (NWIC), the Native American Heritage Commission (NAHC) Sacred Lands File, a <br />review of all previous technical studies and recorded cultural resources, a paleontological records <br />search at the University of California Museum of Paleontology (UCMP), and a site survey. <br />Rincon Consultants, Inc. conducted a historical resources assessment (HRA) analyzing the historical <br />significance of the four existing buildings and associated accessory structures on the project site in <br />October 2021. This assessment included an archival search and reconnaissance of the project site <br />and its surroundings (included as Appendix HRA). <br />a. Would the project cause a substantial adverse change in the significance of a historical resource <br />pursuant to §15064.5? <br />The subject property is not identified as a historic resource by the National Register of Historic <br />Places (NRHP) or the California Register of Historic Places (CRHP) (Appendix HRA). The nearest <br />historic resource identified is the Casa Peralta located 1.9 miles north of the site, which is listed in <br />the NRHP, is a California Point of Historical Interest (CPHI), and is on the City’s local register <br />(National Parks Service 2021; City of San Leandro 2016a). The nearest resource identified and listed <br />in the California Historical Resources database is the San Leandro Ball Park located 1.3 miles <br />northwest (California Office of Historic Preservation [OHP] 2021). The San Leandro Ball Park is listed <br />as a point of interest and has a landmark plaque but is not listed as part of the NRHP, CRHP, or as a <br />State Landmark. The results of the NWIC records search identified four previously recorded <br />historical cultural resources within 0.5-mile of the project site, none of which are located within the <br />project boundary (Appendix CRS). <br />Two of the structures on the project site, one of the residences and one of the accessory structures <br />were built in 1939. The other residence and accessory structure were built in 1945 (Appendix HRA). <br />CEQA does not specify an age threshold for historical resources. However, guidance from the OHP <br />recommends that “sufficient time” – typically 50 years – “must have passed to obtain a scholarly <br />perspective” necessary to evaluate the significance of the historical events with which a property is <br />associated (OHP 2021). A threshold of 45 years is recommended because there is often “a five-year <br />lag between resource identification and the date that planning decisions are made” (OHP 1995). <br />Pursuant to CEQA Guidelines Section 15064.5, buildings more than 50 years in age may be eligible
