Vantage to Pomona Heights Chapter 4 230 kV Transmission Line Project FEIS Environmental Consequences PAGE 4-202 strong/moderate to moderate, creating high impacts. Some of these residences have views of the Moxee Valley and Mount Adams, which would be affected by the presence of the route segment (see Appendix C-3: KOP 3). The Project may obstruct the line of sight to Mount Adams (MP 10.2-10.7). High visual impacts on residences would be reduced to moderate impacts in the middleground for approximately 2.5 miles if the existing fire break road was utilized for route segment access and construction because new road grading and clearing would not be necessary, resulting in reduced landscape contrasts. Agency Management Compliance There is no federal land crossed by this route segment. The route segment would comply with the visual standards identified in the Yakima County Comprehensive Plan. The route segment crosses one mile of DNR state trust land. The DNR does not have goals, policies, or standards regarding the management of visual resources. 4.8.5.4 Route Segment 2a Visual Contrasts Structure contrast would be strong along this entire route segment as no existing transmission line infrastructure or other substantial development is located within this corridor. Some new road construction would be necessary along this route segment resulting in the removal of grassland or other herbaceous ground cover; therefore, landscape contrasts would be moderate to weak, depending on the slope. Overall, Project contrasts would be strong/moderate and in limited areas, strong. Scenic Quality Impacts and Development Character Scenic quality impacts would be moderate for this route segment, with the vertical H-frame structures and linear features of the conductors would contrast with the simple rolling, undulating, and horizontally flowing lines of the landforms of the Yakima Ridge. Sensitive Viewer Impacts The nearest sensitive viewers are residences located at the east end of Postma Road, who would have middleground views of typically strong-moderate Project contrasts. Residual impacts on viewers would be low. Impacts on residences would typically be moderate and high in a limited area (MP 0.7-0.8) where strong contrasts occur. Agency Management Compliance There are no federal or state lands crossed by this route segment. The route segment would comply with the visual standards identified in the Yakima County Comprehensive Plan. 4.8.5.5 Route Segment 2b Visual Contrasts Structure contrast would also be strong along this entire route segment because no existing or related transmission lines currently exist in this corridor. Landscape contrast varies due to the presence of intermittent two-track roads and variable vegetation. New road construction would create visual contrasts in slopes of up to 30 percent and work pad construction would require grading and vegetation removal. Most of this route segment would create strong to strong-moderate visual contrasts. The use of JBLM YTC fire access roads would somewhat reduce visual contrasts by reducing the extent of necessary road construction where the route segment is located adjacent to the base, but on private or BLM-owned land. However, because this route segment is located in the background or seldom seen distance zone for high and moderate sensitivity viewers because the route is located in a Class C landscape and because Project
