Vantage to Pomona Heights Chapter 3 <br />230 kV Transmission Line Project FEIS Affected Environment <br /> PAGE 3-299 <br />Route Segment NNR-3 corresponds to 36.5 acres of soils with high water erosion potential, 0.0 acres of <br />soils with high wind erosion potential, and 137.0 acres of soils with low soil restoration potential. <br />3.15.4.13 Route Segment NNR-4 <br />Route Segment NNR-4 crosses MR, east of I-82. The route segment crosses a Class B structure fault <br />associated with the Saddle Mountains Fault System. The route segment is all classified as extremely low <br />to low liquefaction susceptibility and crosses no landslide deposits—the six-mile study area contains a <br />few small landslide deposits and pockets of low-to-moderate liquefaction susceptibility. The route <br />segment crosses four intermittent/ephemeral creek washes. <br />Route Segment NNR-4 corresponds to 9.5 acres of soils with high water erosion potential, 0.0 acres of <br />soils with high wind erosion potential, and 20.9 acres of soils with low soil restoration potential. <br />3.15.4.14 Route Segment NNR-5 <br />The short Route Segment NNR-5 skirts the southern edge of Badger Pocket, a small low area surrounded <br />by MR, the Saddle Mountains, and the Boylston Mountains. The six-mile study area contains a few Class <br />B structure faults associated with the Saddle Mountains Fault System. The route segment is all classified <br />as extremely low to low liquefaction susceptibility and crosses no landslide deposits—the six–mile study <br />area contains a few small landslide deposits. The route segment crosses two intermittent/ephemeral creek <br />washes. <br />Route Segment NNR-5 corresponds to 38.7 acres of soils with high water erosion potential, 0.0 acres of <br />soils with high wind erosion potential, and 0.8 acre of soils with low soil restoration potential. <br />3.15.4.15 Route Segment NNR-6 <br />Route Segment NNR-6 crosses the Saddle Mountains, an anticline feature, and traverses the mountains’ <br />northern slopes. The route segment roughly follows the Class B Saddle Mountains Fault System and <br />associated structure faults. Along the north-facing slopes of the mountains, the route segment passes <br />through several historic/quaternary landslide deposits. Recent movement was not evident in aerial <br />photography; however, to maintain the stability of these features field review and determination of BMPs <br />for this area would be prudent. The landslide deposits are classified as low to moderate liquefaction <br />susceptibility. The six-mile study area contains one small strip of moderate to high liquefaction <br />susceptibility along Johnson Creek. The route segment crosses five intermittent/ephemeral creek washes. <br />Route Segment NNR-6 corresponds to 33.2 acres of soils with high water erosion potential, 0.0 acres of <br />soils with high wind erosion potential, and 12.4 acres of soils with low soil restoration potential. <br />3.15.4.16 Route Segment NNR-7 <br />Route Segment NNR-7 traverses along the Saddle Mountains’ northern slopes. The route roughly follows <br />the Class B Saddle Mountains Fault System and associated structure faults. The six-mile study area <br />contains several small historic/quaternary landslide deposits and the route segment passes through one of <br />them. Recent movement was not evident in aerial photography; however, to maintain the stability of these <br />features field review and determination of BMPs for this area would be prudent. The landslide deposits <br />are classified as low to moderate liquefaction susceptibility. The six-mile study area contains a few small <br />strips of moderate to high liquefaction susceptibility along creeks. The route segment crosses 13 <br />intermittent/ephemeral creek washes. <br />Route Segment NNR-7 corresponds to 9.7 acres of soils with high water erosion potential, 0.0 acres of <br />soils with high wind erosion potential, and 129.5 acres of soils with low soil restoration potential.
