Vantage to Pomona Heights Chapter 4 230 kV Transmission Line Project FEIS Environmental Consequences PAGE 4-217 Pulling and tensioning sites would also cause short-term landscape and structure contrasts. The presence of a helicopter during the stringing of the transmission line conductor wires would cause short-term structure contrasts, potentially disrupting views or scenic vistas. The temporary structure work areas, turn- around areas, and staging areas would cause low impacts due to the duration of landscape and structure contrasts. Impacts from light sources would not occur because construction would be limited to daylight hours. The potential for glare from the transmission line conductors would be reduced with the use of non-specular conductors (RDF VIS-6). Sensitive Viewer Impacts Huntzinger Road travelers, recreationists using the Columbia River corridor below Priest Rapids Dam, and John Wayne Pioneer Trail users would view weak Project contrasts in the immediate foreground and foreground. From the north, the route segment would be viewed behind the existing Pomona-Wanapum 230 kV, Wanapum-Wind Ridge 230 kV, Vantage-Schultz No.1 500 kV, and Schultz-Wautoma No.1 500 kV transmission lines from the John Wayne Pioneer Trail where the route segment and existing lines cross the trail. Low impacts are expected due to the existing transmission lines visual influence and weak contrasts. On the east side of the Columbia River, impacts would result from SR-243 travelers viewing the route segment briefly as it crosses the highway and residences viewing the route segment from Wanapum Village. Both sensitive viewers would see the route segment in the context of the Priest Rapids Dam and existing transmission line corridor with an industrial development character. Low impacts would result on these viewers. Ginkgo Petrified Forest NNL’s Wanapum Recreation Area boat launch is located in the in the seldom seen distance zone within the Project study area and views are typically screened by topography. Therefore low or no impacts on the NNL are expected from Route Segment NNR-8. Agency Management Compliance BLM Interim VRM Class III lands are crossed between MP 0.0 and MP 0.4. Route Segment NNR-8 would be compliant with the Interim VRM Class III from KOP 21 and Huntzinger Road, the nearest viewpoints, because weak and weak-moderate contrasts would be seen in the immediate foreground and foreground distance zones. Therefore, the route segment would be compliant with the Interim VRM Class III. Route Segment NNR-8 would be consistent with the Kittitas County Comprehensive Plan and Grant County PUD 2010 Final Shoreline Management Plan. 4.8.5.18 Route Segment MR-1 Visual Contrasts Structure contrasts would typically be strong along most of this route segment because no existing transmission lines or similar infrastructure is located in the vicinity of Route Segment MR-1. Landscape contrasts are variable depending on the route segment’s proximity to existing roads, slope, and dominant vegetation cover. Most of the route segment would create strong-moderate or strong Project contrast. Pulling and tensioning sites would also cause short-term landscape contrasts and structure contrasts. The presence of a helicopter during the stringing of the transmission line conductor wires would cause short- term structure contrasts, potentially disrupting views or scenic vistas (e.g., toward the Cascade Mountains). The temporary structure work areas, turn-around areas, and staging areas would cause low impacts due to the duration of landscape and structure contrasts. Impacts from light sources would not occur because construction would be limited to daylight hours. The potential for glare from the transmission line conductors would be reduced with the use of non-specular conductors (RDF VIS-6).
