appropriate representative soil par•~meters of the in situ • soils), the calculations show that the slopes will have adequate saf~aty factors that exceed regulatory requirements. SCC and their consultants strongl}~ believe it would be technically incorrect to arbitrari:Ly assign ground water elevations to any of the cut and fill slope stability analyses included in the report. Such approach is biased since it misrepresent:> field conditions and ]zas no practical value. NWWC agreed .in the report that seepage probably would not be encountered. Effects of seepage and groundwater in this context are +two entirely different i::sues. SCC is aware there is a remote possibility that seepage may induce local limited sloughing in cut slopes. However, such occurrences are extremely difficult to predict. The consequences of such limited sloughing are generally insignificant if local slope repairs and maintenance are performed. In the most unlikely event such unpredictable sloughing would occur, SCC is prepared to repair the affected slope area :by installing toe drains or other appropriate remedial measures in a timely manner. In the unlikely event that ground water is encountered, the following measures will be taken: Road Embankment Stabilization: Embankments constructed on • slopes steep~ar than 5H:1V will be benched in to the sidehill. The minimum bench width will be ten feet horizontally. Benches will be placed every ten feet in elevation difference. If ground water is present, the benches will be sloped to drain to the center of the embanN:ment bench. A gravel (French) drain will be conducted at the bank of each bench and sloped to a central "French" downdi-ain. The gravel bench drains will be wrapped with an appropriate geotextile filter fabric to prevent clogging of the drain. Road Cut Stabilization: In road cuts where ground water is encountered, the slope will be reduced, if possible. The ground water will be intercepted with a lined channel to carry the runoff away from the cut face. A gravel, geotextile-lined channel will be constructed diagonally along the face and exit into the rip:rapped section of the road ditch. An appropriate positive road ditch gradient will be maintained to transport the runoff 1°rom the cut area and discharge the water to a predetermined area. Tab 15 - Hvdrolovic Monitoring Plan 49.
