A <br />second inspection was conducted on Sunday morning, August 3, 1997. <br />2 <br />RPE: Site lines for completed slope excavations (south slope) for Phase lA and 1B showed <br />no movement on July 31 or August 3. Phase 1C cut slopes (in progress) were also stable. <br />The RPE access road cut slope experienced minor Bluffing into the road ditch, however, the <br />ditch remains open and free running. <br />Sylvester Gulch Main Road: Cut slopes and other disturbed slopes adjacent to widened <br />sections of the lower Sylvester Gulch Road showed no failures or slumping on July 31 or <br />August 3. No additional failures, movement, or new cracking was observed at the failed fill <br />area (Stations 62 to 68) on July 31 or August 3. All other pioneered sections of the main road <br />appeared stable, including both approaches to the main crossing (F-walls). <br />Landing #2 Road: The light-use road to Landing #2 was inspected on August 3. Soil cut <br />slopes were dry and appeared stable, with no water observed in any cut slope. Numerous six <br />inch size rocks had fallen into the road; probably due to the Thursday rains, however, no road <br />or ditch washout was evident. <br />Dewatering Borehole Road: The three sight lines (upper, middle, lower) between Stations <br />15+00 and 19+00 were observed on July 31 and August 3. The sight lines and slope <br />conditions remain as previously reported, with some additional minor slumping observed after <br />the Thursday rains. Minor seepage associated with sandstone strata along this road is <br />continuing, and construction of French drains in this area are planned. MCC will continue to <br />monitor these slopes. <br />
