Vantage to Pomona Heights Chapter 4 230 kV Transmission Line Project FEIS Environmental Consequences PAGE 4-266 One TCP has been identified within 75 feet of the route segment centerline. Potential physical impacts to archaeological resources along Route Segment NNR-2 are low and there are no identifiable physical impacts to architectural resources. The potential for physical impacts to TCPs is considered at this time to be moderate to high. Visual Impacts All of the land within 250 feet of the centerline of Route Segment NNR-2 has been surveyed for cultural resources. No archaeological resources have been identified and even if sites are discovered in the future, they are unlikely to be sensitive to changes in visual setting. No architectural resources have been identified within the 250 feet of the route segment centerline. One TCP is crossed by Route Segment NNR-2. Visual impacts of Route Segment NNR-2 are anticipated to be moderate to high because one TCP exists within 250 feet of the route segment centerline. Native American Concerns The YNCRP has identified one TCP within 75 feet of the centerline of Route Segment NNR-2. Physical and visual impacts to this TCP are expected to be moderate to high. 4.11.4.12 Route Segment NNR-3 Route Segment NNR-3 is 9.3 miles long. Some of the land crossed is under the jurisdiction of JBLM YTC, BLM, and Washington State Department of Transportation (WSDOT), but a majority of Route Segment NNR-3 crosses private land. Physical Impacts The total amount of land within 75 feet of the route segment centerline is 169 acres. Short-term and long- term ground disturbance along this route segment would total 52.4 acres. Approximately 74 acres (43percent) of the land within 75 feet of the centerline of Route Segment NNR-3 has been surveyed for archaeological resources. Archaeological resources recorded in the area include four unevaluated prehistoric sites (two with talus pits: one with a cairn and the other with a lithic scatter and talus pits) and seven prehistoric isolated finds. All of these resources are unevaluated concerning their eligibility for listing on the National Register. There are no architectural resources within 75 feet of the route segment centerline. Two TCPs are crossed by Route Segment NNR-3. Overall, the potential for physical impacts to archaeological resources is low to moderate, with a somewhat higher potential for impacting archaeological sites near drainages. There would be no identifiable physical impacts to architectural resources. The potential for physical impacts to TCPs is assumed to be moderate to high. Visual Impacts One hundred forty-four acres (25 percent) of the land within 250 feet of the centerline of Route Segment NNR-3 have been surveyed for archaeological resources. The only recorded archaeological resources, three prehistoric sites and eight isolated finds, are usually unlikely to be sensitive to changes in visual setting. However, sites with talus pits may be visually sensitive.
