Soil Investigations for Data Collection in the Delta Initial Study/Proposed Mitigated Negative Declaration 136 were reviewed. Also examined were historical maps (BLM 2019; USGS 2019) and aerial photography (NETR 2019). Finally, information on previous pedestrian surveys within the Study Area was examined from CHRIS data and DWR projects recorded in the Cultural Resources Section’s Geodatabase. Only approximately 22% of the Impact Areas have previous field studies (including survey coverage, subsurface testing, and/or excavations) reported that we know of at this time. Of the areas previously studied, there are nine previously recorded cultural resources within the Study Area, three of which have not been previously evaluated for eligibility as a historical resource for the California Register of Historic Resources (CRHR). Two of these have been provided recommendations for ineligibility based on an examination of past studies and information about the resource. No previously identified cultural resources, including those potentially eligible as historic properties, are located within the Impact Areas for the overwater boring locations. In addition, no locations from the AWOIS are located within those Impact Areas. Table 5 summarizes all previously recorded cultural resources within the study area. P-39-004492 is the only previously recorded resource that has both built environment and archaeological components. The resource was not officially evaluated but was suggested to have potential eligibility for the CRHR under Criteria 1, 2, and 4 in 2003 (Kelley and Huster 2003). The report suggested that the potential for data under criteria 3 would have been located near the farmhouse structures, outside of this project’s Study Area. Unfortunately, all built environment components of the site, except for the levees along the borders of the site, were removed as part of preparation for housing development by 2006 according to the site record. This was confirmed by examining aerial photography from 2005 and 2009 (NETR 2019). The site record additionally noted that test trenches had been excavated by LSA Associates, Inc., in 2006, and that only recent materials had been found. Based on this information, the site is lacking in the necessary integrity that could make it eligible under Criteria 1-4 for both the built environment and archaeological components. Therefore, this site is recommended ineligible for CRHR. P-07-004730 was previously evaluated as ineligible for the NRHP (Germano 2005) and the evaluation was concurred on by the Office of Historic Preservation in 2006. The ineligibility evaluation for the NRHP for P-07-004730 provides enough information to justify a recommendation that the resource should also be evaluated as ineligible for CRHR. P-57-000132 is previously unevaluated because, in studies where it has been within the project area, cultural resource specialists tend to concur that the oak tree groves and associated natural habitat are not possible to define as either an archaeological or historical resource (Peirce 2017; Scher et al. 2018). Though the valley oaks may technically be old enough to count as historic in age, they are naturally occurring groves. Thus, this resource is considered ineligible for CRHR. However, this does not preclude this resource from being considered a Tribal Cultural Resource as valley oaks
