Vantage to Pomona Heights Chapter 3 230 kV Transmission Line Project FEIS Affected Environment PAGE 3-210 Steep drainages within the Saddle Mountains that have eroded cliffs and ribbons of more variable vegetation deviates from the dominant sagebrush slopes. The development character is dominated by vertical, industrial structures expressed by the existing steel lattice and wood H-frame structures of Wind Ridge-Wanapum 230 kV, Schultz-Wautoma 500 kV, and Schultz-Vantage 500 kV transmission line corridor. Sensitive viewers are limited to the John Wayne Pioneer Trail (Iron Horse Trail), which parallels the route segment within the immediate foreground and foreground on the west and the middleground on the east, generally (KOP 21 - John Wayne Trail). Ginkgo Petrified Forest NNL (Wanapum State Park boat launch) is located in the in the seldom seen distance zone within the Project study area and views are typically screened by topography. The existing transmission lines currently in the Project viewshed dominate the visual context of NNR-7. Two-track trails and transmission line service roads are the most significant modifiers of the landscape in this area. 3.8.4.17 Route Segment NNR-8 Route Segment NNR-8 shares the same alignment with Route Segment 3b where the line crosses the Columbia River on its extreme north end. This route segment crosses the Columbia River just south of the Wanapum Dam in an Industrial/Utility Development Character Area adjacent to four other transmission lines of various voltages (230 to 500 kV). The route segment also crosses BLM land and Huntington Road on the west side of the Columbia River in a largely undeveloped Class B Scenic Quality landscape. Interim VRM Class III land is crossed by this route segment. Route Segment NNR-8 also crosses BLM VRI Class IV lands as identified by the 2010 study. Sensitive viewers associated with this route segment include recreationists using the John Wayne Pioneer Trail and associated facilities who would view the route segment in the immediate foreground, as well as Huntzinger Road travelers and residences associated with Wanapum Village. The route segment would also be potentially viewed in the background by recreationists using the Huntzinger Boat Launch, Priest Rapids Recreation Trail, Desert Air Dock, Priest Rapids Dock, and dispersed users of Priest Rapids Reservoir-Columbia River. Travelers using SR-243 would also potentially view the route segment in the immediate foreground distance zone where the line would cross the highway. Ginkgo Petrified Forest NNL (Wanapum State Park boat launch) is located in the seldom seen distance zone within the Project study area. Route Segment NNR-8 also crosses a moderate BLM sensitivity level rating unit as identified by the 2010 study. The visual context of this Route Segment NNR-8 is dominated by the industrial features of the Wanapum Dam, existing transmission lines, and Vantage Substation along its entire route. 3.8.4.18 Route Segment MR-1 Landscape character along this route segment is similar to Route Segments NNR-3 and NNR-4, with relatively undeveloped, rolling sagebrush steppe, and the I-82 transportation corridor and associated Manastash Ridge (MR) Viewpoints. Several stream corridors that are crossed have some rocky outcropping and riparian vegetation which adds to visual interest. As with Route Segment NNR-5, the landscape character in the vicinity of Route Segment MR-1 is expressed as an interface between the largely undeveloped, rolling, sagebrush dominated landscape of the army base, and the rural, agricultural landscape of Badger Pocket. Scenic Quality is Class C along this route segment. Visual sensitivity is associated with Route Segment MR-1 is associated primarily with the MR Viewpoints (east-bound and west-bound) that would have immediate foreground, foreground, and middleground views of the route segment as it crosses the interstate. As with Route Segment NNR-3, this
