<br />appropriate representative soil par:~meters of the in situ • <br />soils), the calculations show that the slopes will have <br />adequate safety factors that exceed regulatory requirements. <br />SCC and their consultants strongl}~ believe it would be <br />technically incorrect to arbitrarily assign ground water <br />elevations to any of the cut and fill ;slope stability analyses <br />included in the report. Such approach is biased since it <br />misrepresent:; field conditions and teas no practical value. <br />NWWC agreed inn the report that seepage probably would not be <br />encountered. Effects of seepage and groundwater in this <br />context are t:wo entirely different issues. <br />SCC is aware there is a remote possibility that seepage may <br />induce local limited sloughing in cut: slopes. However, such <br />occurrences are extremely difficult to predict. The <br />consequences of such limited sloughing are generally <br />insignificant: if local slope repairs and maintenance are <br />performed. In the most unlikely event such unpredictable <br />sloughing would occur, SCC is prepared to repair the affected <br />slope area k>y installing toe drains or other appropriate <br />remedial mea:;ures in a timely manner. <br />In the unlikely event that ground water is encountered, the <br />following measures will be taken: <br />Road Embankm~=_nt Stabilization: Embankments constructed on • <br />slopes steeper than SH:lV will be ben~~hed in to the sidehill. <br />The minimum bench width will be 'ten feet horizontally. <br />Benches will be placed every ten feet in elevation difference. <br />y~ If ground water is present, the benches will be sloped to <br />drain to the center of the embankment bench. A gravel <br />(French) drain will be conducted at the bank of each bench and <br />sloped to a central "French" downdrain. The gravel bench <br />drains will be wrapped with an appropriate geotextile filter <br />fabric to prE:vent clogging of the drz:in. <br />Road Cut Stabilization: In road cuts where ground water is <br />encountered, the slope will be reduced, if possible. The <br />ground water will be intercepted with a lined channel to carry <br />the runoff away from the cut face. A gravel, geotextile-lined <br />~~ channel will be constructed diagonally along the face and exit <br />into the riprapped section of the road ditch. An appropriate <br />positive road ditch gradient will be maintained to transport <br />the runoff from the cut area and discharge the water to a <br />predetermined area. <br />Tab 15 - Hvdroloai.c Monitorinc Plaa <br />49. Table 15-7 in Tab 15 lists monitoring procedures for <br />monitoring wells used to collect ground water data during the <br />baseline period. Table 15-8 presents proposed frequencies for • <br />collecting water levels and water duality from monitoring <br />12 <br />
