During ROW acquisition and detailed <br />design (by Pacific Power), the centerline of this route segment would be adjusted to avoid the need for <br />removal of residential dwellings or related structures from the route segment’s ROW corridor. Therefore, <br />with prudent adjustments to the location of the route segment, ROW corridor, and structure placement, no <br />direct impacts to existing residential dwellings or related structures are foreseen. Moderate impacts within <br />a residential area would result from long-term elimination or limitation of any structure placement or <br />development under the proposed transmission line or within its ROW corridor. <br />Overall impacts would be moderate because the Project would eliminate the potential for further <br />development (see Table 4.4-2) because the establishment of the ROW would substantially restrict the <br />types of development that are allowed. Much of this route segment is located within or adjacent to Sage <br />Trail Road’s ROW and single pole structures would be used along this route segment. Higher impacts <br />would occur where the route segment ROW corridor would traverse residential land parcels and heavy <br />angle transmission line structures would be utilized affecting a higher proportion of undeveloped <br />residential land with the necessary guy wires and additional wood pole structures. However, impacts <br />would remain moderate. <br />This route segment also crosses land classified as Farmland of Unique Importance causing 1.7 acres of <br />long-term disturbance and crosses Prime Farmland causing less than 0.1 acres of long-term disturbance <br />and moderate impacts to these lands. However, this is currently non-agricultural land, so impacts would <br />be moderate because no farmland would be converted to non-agricultural uses. <br />The route segment would cross private land in Yakima County, and would be consistent with the Yakima <br />County Comprehensive Plan (2007). Route Segment NNR-1a/NNR-1 would be subject to the Yakima <br />County Code (YCC) 19.18.260(4) – Linear Transmission Facilities, and would require a Type II review. <br />Moderate impacts would occur for 2.4 miles of this route segment. <br />4.4.4.2 Route Segment 1b <br />Route Segment 1b would cause approximately 11.2 acres of long-term impacts on military land use on the <br />perimeter of the Joint Base Lewis-McChord Yakima Training Center (JBLM YTC) in Training Areas 11, <br />13, and 10. Military operations in this area would be minimally affected; however, because the route <br />segment would be on the perimeter of training activity areas and new transmission line structures would <br />be located adjacent to an existing fire break road. Impacts would be moderate, because military activities <br />could continue to occur. Short-term impacts would total 46.3 acres on military land use areas. <br />This route segment also crosses land classified as Farmland of Statewide Importance and Prime Farmland <br />if Irrigated causing 1.8 acres of long-term disturbance and 4.6 acres of long-term disturbance, <br />respectively. However, this is non-agricultural land.
