Biological Resources Evaluation Report <br /> Griffith Energy Project <br /> CRLF)and BUOW or SJKF. In the 150-meter buffer, a shallow ditch and berm ran along the southern side <br /> of W Patterson Pass Road and although the dominant community in this area was Avena spp. — Bromus <br /> spp. herbaceous semi-natural alliance, this area also supported other non-native plants including Russian <br /> thistle, poison hemlock (Conium maculatum), and star thistle (Centaurea sp.). <br /> Disturbed. The disturbed area shown in Figure 5 consisted of a graded, dirt pad adjacent to W Patterson <br /> Pass Road. Other disturbed areas consisted of narrow, dirt roads, which have not been individually <br /> mapped. These areas occurred only within the 150-meter buffer. <br /> Developed.The developed areas shown in Figure 5 consisted of two paved roads(W Patterson Pass Road <br /> and Midway Road). <br /> Open Water. This area only occurs within the 150-meter buffer. At the time of survey, this area held <br /> standing water that was a maximum of approximately 0.5 feet deep. This area was bounded by native salt <br /> grass (Distichlis spicata) and Avena spp. — Bromus spp. herbaceous semi-natural alliance. This pool is <br /> unlikely to support special-status amphibians because it is shallow and unlikely to hold water for 4 to 6 <br /> months; however, migrating shorebird species were observed using this area and are likely to do so during <br /> winter and spring. <br /> Residential Development. There were several residential areas within the Project boundary and 150- <br /> meter buffer. All tree species found within the BSA were within these areas. Therefore, areas mapped as <br /> residential are the most likely areas within the BSA to host tree-nesting or structure-nesting bird species or <br /> nesting raptors. <br /> 5.3 Soil <br /> The NRCS web soil survey indicates that the Project Property is comprised of Clear Lake clay drained, 3 <br /> to 7 percent slopes (CdB), Diablo clay, 7 to 15 percent slopes (DbC), Calla-Carbona complex, 8 to 30 <br /> percent slopes (114), Calla-Carbona complex, 30 to 50 percent slopes (115), Carbona clay loam, 2 to 8 <br /> percent slopes (123), and Linne clay loam, 3 to 15 percent slopes (LaC) (USDA NRCS 2021). <br /> Tetra Tech, Inc. 5-4 July 2023 <br />
