City of Pleasanton—Hidden Canyon Residences and Preserve Cultural Resources and Tribal Cultural Resources Draft EIR 3.4-8 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec03-04 Cultural-Tribal Cultural Resources.docx the Shriner property. In contrast, only one structure is present within the Lester property that appears to conform to the location of the single 1878 structure. A 1949 aerial photograph shows a building within the largest Lester Parcel (APN 941-2006-2-6) north of the seasonal drainage within Devaney Canyon and adjacent to a small knoll with oak trees. This building appears to have been short lived and does not appear on the next available aerial photograph taken in 1958 (e.g., Cornerstone 2014: Appendix D). The 1961 USGS Livermore and 1980 USGS Dublin topographic quadrangle maps show “Dublin Canyon” rather than Hayward or Haywards Pass. Two structures—one each in the Shriner and Lester property—and unpaved road along the south side of intermittent creek within Devaney Canyon are present. The Creek & Watershed Map of the Pleasanton & Dublin Area shows no modification of the intermittent creek within Devaney Canyon, nor Dublin Creek located along the north side of Dublin Canyon Road just north of the northeast portion of the proposed project. 3.4.3 - Methodology Archaeological Resources Assessment Basin Research Associates (BASIN) conducted an archaeological resources assessment to determine whether significant archaeological resources could be present at the project site. For the assessment, BASIN obtained information from a records search of the California Historical Resources System, NWIC. Additionally, BASIN summarized the literature and archival information as well as the prehistoric and historic context, provided information about the NAHCs review of the Sacred Lands Inventory and NAHC consultation, and presented the results of an archaeological field inventory. Historic Architecture Evaluation A Historic Architecture Evaluation Report of two houses on the project site was conducted by Architectural Historian Ward Hill in April 2018. The two existing houses and associated structures at 11033 and 11021 Dublin Canyon Road were evaluated to determine whether these structures are architecturally or historically significant resources. The evaluation considered the structures’ eligibility for the CRHR based on research and a field survey, including visual inspection of the structures, research of archived documents and historic records, and consultation with local historians. Record Searches and Pedestrian Survey to Identify Existing Cultural Resources Northwest Information Center On May 3, 2023, an updated records search for the project site and a 0.5-mile radius beyond the project site was conducted at the NWIC located at Sonoma State University in Rohnert Park, California. The current inventories of the NRHP, the CRHR, the California Historical Landmarks (CHL) list, the CPHI list, and the BERD for the County of Alameda were also reviewed to determine the existence of previously documented local historical resources.
