4 Environmental Analysis 4.5 Cultural Resources site and crosses the proposed gen-tie corridor. Resource P-39-005337 is the Tesla-Salado- Manteca 115-kV Transmission Line. This resource is not eligible for listing in the CRHR and, therefore, not a historical resource (Price et al. 2022). Historic USGS Map, GLO Plat Map, and Historic Aerial Review Based on historic maps and aerial imagery, the Project area has remained primarily undeveloped and has been used for agricultural purposes (row crops and livestock grazing) since the 1940s. Aerial imagery from 1948 depicts a residential ranch complex consisting of a main building (house), two outbuildings, and several trees located adjacent to the northwest Project boundary (previously recorded site P-01-010500: Haera-Brockman-Griffith Ranch). The Project area appears disced in 1948, 1958, 1966, 1971, and 1979. By 1993, one of the outbuildings associated with the P-01-010500 eastern boundary is no longer extant. By 2018 and 2019, the residential building (main house), fence line/corral, and a structure (open barn) associated with P-01-010500 (Haera-Brockman-Griffith Ranch) are no longer extant, the area appears graded, and several trees were removed. It appears only one original outbuilding from 1948 image may remain. No buildings, structures, or features were observed within the Project area. Federal Land Patent Review Review of historic land patents for the Project area (Township 2 South, Range 4 East, southeast quarter of Section 32) indicate Reinhold Haera purchased an agricultural scrip patent in 1872 (see the Historic Overview in Section 4.5.1.2 for historic information). Native American Heritage Commission Sacred Lands File Search Tetra Tech contacted the NAHC on November 15, 2021, to request an SLF Search. The NAHC replied on December 29, 2021, that results were negative for Native American tribal resources within the Project area and provided a list of local Native American contacts. The lead state agency is responsible for government-to-government tribal consultation compliance under the CEQA and AB 52 or Senate Bill 18. Consultation initiated by San Joaquin County is detailed in Section 4.16, Tribal Cultural Resources. 4.5.3.2 Archaeological Survey Results 106-acre Land Parcel Portion of the Project Site Qualified archaeologists conducted an intensive pedestrian survey of the 106-acre land parcel on March 2, 2022 (Farrell and Kitchel 2022). The ground surface visibility was poor to good (15 to 80 percent) throughout the Project area. Survey transects were walked closer together in areas of heavy vegetation (i.e., 5- to 10-meter transects). Several cows and calves were grazing on the property during the survey and active ground squirrel burrows were present. Loose soils from these burrows were examined for any signs of cultural resources (e.g., artifacts, midden soils). No cultural material was observed within the Project site. Gen-tie Corridor and PG&E Tie-in Portion of the Project Site Qualified archaeologists and architectural historian conducted an intensive pedestrian field survey of the land parcel south of the PG&E Tesla Substation that included the gen-tie corridors on September 28, 29, and 30, 2021, and on June 7, 2022 (Price et al. 2022). Ground visibility was good, and the field team walked transects spaced no greater than 15 meters apart across the Griffith Energy Storage Project 4.5-14 Tetra Tech/SCH 2022120675 Draft Environmental Impact Report August 2023
