Vantage to Pomona Heights Chapter 4 230 kV Transmission Line Project FEIS Environmental Consequences PAGE 4-259 the Burlington Northern and Santa Fe Railroad corridor, and JBLM YTC. Therefore, impacts to the resource are at this time expected to be low (Lally and Camuso 2013; Camuso and Lally 2014). 4.11.4.2 Route Segment 1b Route Segment 1b is just within the JBLM YTC border and parallels an existing firebreak road. The route segment is 12.5 miles long. Approximately 55 percent of this route segment has been covered by cultural resource surveys resulting in the identification of 18 cultural resources consisting of prehistoric lithic scatters, historic debris scatters and isolated occurrences of both prehistoric and historic artifacts. Physical Impacts Short-term and long-term ground disturbance along this route segment would total 57.9 acres. Approximately 55 percent of the land within 75 feet of the centerline of Route Segment 1b has been previously surveyed for cultural resources resulting in the identification of 18 archaeological sites and isolated finds. One of the sites is recommended eligible for listing on the National Register and future research is needed to assess the National Register eligibility of the rest. There would be no physical impacts to architectural resources. Overall, the potential for physical impacts to cultural resources is high, with a somewhat higher potential for impacts near drainages. Visual Impacts Little of the land within one mile and none of the land within 250 feet of the centerline of Route Segment 1b had been previously surveyed for cultural resources. The only recorded cultural resources within one mile are archaeological sites, which are unlikely to be sensitive to changes in visual setting. Visual impacts are anticipated to be low because undiscovered archaeological sites, should they exist, would probably not be visually sensitive, and there are no recorded architectural resources. Native American Concerns The YNCRP has identified six resources of special concern in the vicinity of Route Segment 1b. However, as discussed for Route Segment 1a/NNR-1, the integrity of the visual setting has been compromised. The resources are located 3 to 7 miles from the centerline of this route segment. Impacts to the resources from the presence of a new transmission line are expected to be low (Lally and Camuso 2011). 4.11.4.3 Route Segment 1c Route Segment 1c is on private land just outside JBLM YTC and parallels the installation boundary. The route segment is 12.9 miles long and is very close to and just south of Route Segment 1b. There has been very limited survey within 1.0 mile of Route Segment 1c. There are no previously recorded cultural resources in the area. Physical Impacts Short-term and long-term ground disturbance along this route segment would total 70.9 acres. None of the land within 75 feet of the centerline of Route Segment 1c has been previously surveyed for cultural resources and there are no previously recorded cultural resources in the area. If archaeological sites exist along Route Segment 1c, they would most likely be near drainages. There would be no physical impacts to architectural resources. Overall, the potential for physical impacts to cultural resources is low, with a somewhat higher potential for impacting archaeological sites near drainages.
