<br /> <br />Mr. Dan Hernandez <br />October 21, 1989 <br />Page Three <br />Recommendation 5. Slopes should be designed for a factor of safety <br />exceeding 1.5, reference the enclosed technical literature which has <br />been highlighted for your use. Perhaps the State Highway Department <br />would have en engineer who could assist the Mined Lend Division with <br />a second opinion on this subject. <br />Concern 4. The current CAP does not address other areas along the <br />access road which have been harmed by erosion and sedimentation. <br />Specifically run-away truck temps have been cut at what appears to <br />be beyond boundary conditions and probably without the lend owners <br />permission. There may be a good need for these safety items however <br />the cut areas need to be seeded for erosion control. The <br />report repeatedly addressee north facing elopes with associated growing <br />charecterietics. We would expect after geotechnicel modifications, <br />the majority of the elopes would be facing easterly, with the access <br />road et the top or west aide of the remedial elope work. Immediate <br />retention of the elopes is beneficial. Work was originally requested <br />to be corrected by October 30, 1989, it ie now obvious that date <br />cannot be mat. <br />Recommendation 6. Unleae the geotechnicel engineer indicates a problem <br />with mulch or mulch and netting, we would recommend this quicker <br />erosion control technique. With regards to tree planting, the <br />State Forest Service recommends a 700-800 tree/acre planting <br />program, reference page two in the July 11, 1989,, division report <br />titled "Assessment of the Application of Criteria for the <br />Achievement of Forest ea a Post Mining land Use." I assume these <br />ere bare root stock, if the operator plants containerized stock, <br />whet would be the Forest Service recommendation? Ia it fair to <br />plant seedlings for the lose of mature trees? In my opinion, it is <br />not fair. <br />
