<br />-33 - <br /> <br />suitable for construction. We strongly advise that construction or <br /> <br />removal of material be completely avoided in the area adjacent to the <br /> <br />main road since this constitutes the critical toe of the unstable mass. <br /> <br />As long as this is observed, the flat areas past the toe of the slope <br /> <br />are probably moderately safe. <br /> <br />Hermit's Hideaway Area (6) <br /> <br />This area is located on the alluvial deposits at the mouth of the <br />combined Milton Creek and Raspberry Creek watershed, and adjacent to <br />the flood plain of the Crystal River. According to our understanding, <br /> <br />there is an older subdivision in this area, and it is currently slated <br /> <br />for single family dwellings on one-half to one-third acre sites. <br />The combined Milton-Raspberry watershed has a drainage area of <br /> <br />approximately 4,700 acres, which is considerably larger than the trou- <br /> <br />blesome Carbonate-Slate watershed. Like the Carbonate-Slate system, <br /> <br />this drainage basin has extremely steep gradients and superabundant <br /> <br />sediment supply in the steep upper reaches of the watershed. The danger <br /> <br /> <br />from mud floods is probably not serious since much of the debris consists <br /> <br /> <br />of coarse intrusive igneous rock, but the possibility of serious flood- <br /> <br /> <br />ing and erosion problems in the Hideaway area during rapid storm runoff <br /> <br />must be carefully evaluated and taken into account in planning for this <br /> <br />tract. <br /> <br />Other conditions of the Hideaway area which should be evaluated in <br /> <br /> <br />possible area development include: (1) rather shallow water table condi- <br /> <br /> <br />tions; (2) very granular soil (probably deficient in soil colloids); <br /> <br /> <br />(3) very high percolation rates; (4) very high density of proposed <br /> <br /> <br />housing units; (5) plans for using shallow ground water for domestic <br /> <br /> <br />supply. This combination of conditions suggest to us a definite possible <br />
