Vantage to Pomona Heights Chapter 3 230 kV Transmission Line Project FEIS Affected Environment PAGE 3-251 for this route segment and no previous surveys have been conducted in association with other projects. Therefore, none of these acres have been surveyed (Table 3.11-1). No cultural resources have been documented or TCPs identified within either the 150-foot wide corridor or the 500-foot wide corridor of Route Segment 2a (Tables 3.11-2 and 3.11-3). 3.11.4.5 Route Segment 2b There are 298 acres within the 150-foot wide corridor of Route Segment 2b. Of this total, only one acre (0.3 percent) has been previously surveyed for cultural resources. A total of 995 acres exists within the 500-foot wide corridor. Only five acres (0.5 percent) in this corridor have been surveyed (Table 3.11-1). Project-specific cultural resource surveys have not been conducted for this route segment and the acreages of surveys completed were associated with other projects. No cultural resources have been documented and no TCPs have been identified within either the 150-foot wide or 500-foot wide Route Segment 2b corridors (Tables 3.11-2 and 3.11-3). 3.11.4.6 Route Segment 2c A total of 330 acres of land exist within the 150-foot wide corridor of Route Segment 2c and 1,102 acres exist within the 500-foot wide corridor. Project-specific cultural resource surveys have not been conducted for this route segment and no previous surveys have been conducted in association with other projects. Therefore, none have been previously surveyed for cultural resources (Table 3.11-1). No cultural resources have been previously recorded within the 150-foot wide corridor of Route Segment 2c. One prehistoric lithic scatter has been documented within the 500-foot wide corridor. This site has not been evaluated for eligibility for listing in the National Register (Tables 3.11-2 and 3.11-3). No TCPs have been documented within the Route Segment 2c corridors. 3.11.4.7 Route Segment 2d Within the 150-foot wide corridor of Route Segment 2d there are 128 acres of land of which five acres (3.9 percent) have been previously surveyed for cultural resources. A total of 431 acres of non-inundated dry land exists within the 500-foot wide corridor; 14 acres (3.2 percent) have been previously surveyed (Table 3.11-1). Two cultural resources have been previously recorded along this route segment. The Hanford Grade of the former Chicago, Milwaukee, St. Paul, and Pacific (C, M, SP, & P) Railroad, occurs within the 150- foot wide corridor and 500-foot wide corridor along the Route Segment 2d centerline at the Columbia River. This portion of the Hanford Grade has not been evaluated for National Register eligibility (Tables 3.11-2 and 3.11-3). A portion of the Route Segment 2d corridor is located within an identified TCP. 3.11.4.8 Route Segment 3a Route Segment 3a is a very short segment (0.1 mile) that facilitates the interconnection of the transmission line into the Vantage Substation and extends west from the 3a-3b-3c route node. All of the 150-foot wide and 500-foot wide corridors along this very short segment have been surveyed for cultural resources (Table 3.11-1). A total of 3 cultural resources have been previously documented within the 150-foot wide corridor of Route Segment 3a, consisting of 2 archaeological sites and 1 architectural resource. A total of five cultural resources have been located within the 500-foot wide corridor that include those mentioned above plus two additional architectural resources (Tables 3.11-2 and 3.11-3). No TCPs have been identified within the 150-foot wide or 500-foot wide corridors. One architectural resource, the Vantage Substation,
