Vantage to Pomona Heights Chapter 3 <br />230 kV Transmission Line Project FEIS Affected Environment <br /> PAGE 3-182 <br />3.7.4 Route Segment Specific Considerations <br />3.7.4.1 Route Segment 1a/NNR-1 <br />This Route Segment parallels the existing Pomona-Wanapum 230 kilovolt (kV) transmission line out of <br />the Pomona Heights Substation for about 4,400 feet and turns north adjoining and paralleling within the <br />existing PacifiCorp electrical distribution line easement for the private section of Sage Trail Road for <br />approximately two miles. Project access would occur from the existing Pomona-Wanapum 230 kV <br />transmission line access road and the private Sage Trail Road. <br />3.7.4.2 Route Segment 1b <br />Route Segment 1b would extend onto the JBLM YTC parallel to an existing fire break road along the <br />JBLM YTC boundary. <br />3.7.4.3 Route Segment 1c <br />The transportation network in Kittitas Canyon where Route Segment 1c parallels and ascends Yakima <br />Ridge is very sparse. Roza Hill Drive, Summerset Drive, Maple Place, Bohoskey Drive, Lamb Road, and <br />E. Norman Road are existing unpaved roads that would provide access along Route Segment 1c. As the <br />route extends south of the JBLM YTC, it turns east and would parallel Mieras Road, a two-lane paved <br />road, for approximately 1.25 miles until the road ends. <br />3.7.4.4 Route Segment 2a <br />The road network in the area of Route Segment 2a is also very sparse and generally undeveloped, <br />consisting of a limited number of dirt roads and two-track roads that extend from SR-24 and Deeringhoff <br />Road across rangeland and cultivated farmland. <br />3.7.4.5 Route Segment 2b <br />This short segment is only accessible from private, 2-track roads extending from Deeringhoff Road and <br />from a fire break road located at the perimeter of JBLM YTC. <br />3.7.4.6 Route Segment 2c <br />This route segment crosses private land that is generally inaccessible by the public. The Bonneville Power <br />Administration (BPA) Midway-Moxee 115 kV transmission line and the PacifiCorp Union Gap – <br />Midway 230 kV transmission line have existing access roads generally parallel to the lines within the <br />existing ROW of the lines and accessible from SR 24. <br />3.7.4.7 Route Segment 2d <br />This route segment would be accessed from two-track road on private lands extending north from SR-24 <br />and Cold Creek Road following the Umtanum Ridge. This area is mostly privately owned land and <br />inaccessible by the public. <br />3.7.4.8 Route Segment 3a <br />Route Segment 3a would be accessible from the two-lane paved access road to the Vantage Substation <br />that extends from SR-243. <br />3.7.4.9 Route Segment 3b <br />Route Segment 3b runs along the western banks of the Columbia River. In Benton County, access to this <br />route segment would be from BPA’s paved access road to the Midway Substation that extends from <br />SR-24 and across an orchard access road to a point where the road transitions into the abandoned <br />Chicago, Milwaukee, St. Paul, and Pacific railroad bed ROW. In Kittitas County, this route segment <br />would be located parallel to Huntzinger Road to the south end of the Auvil Fruit Company. Just south of <br />the Wanapum Dam, the route segment crosses the Columbia River to the Vantage Substation. The route
