due to bends in Coal Creek, and the curvature of the pile, a <br /> failure at this location would probably not have as great an impact <br /> on Coal Creek as a western area failure. In order to help <br /> stabilize this portion of the Old Refuse Pile, seedling trees will <br /> be planted throughout the designated area. Approximately 1,200 <br /> trees will be planted at the three acre eastern project area. <br /> Ponderosa pine, Douglas fir and Blue Spruce have all been observed <br /> to grow on the flanks of the refuse pile. <br /> Attached is a map of the project area, and a series of slides which <br /> depict the project areas. As these are the only copies of the <br /> slides, they should be returned to the files or copied. An <br /> explanation of the slides follows: <br /> 1, 2, 3. Western Project Area. Views to the west, and upslope <br /> toward the top of the area from near the base of the area. Note <br /> surficial failure in slide 1, and hummocky topography typical of <br /> past failures in slides 2 and 3. <br /> 4, 5, 6. Western Project Area. Views to the east, and across <br /> slopes near center of project area. Note steepness of slope, <br /> scarcity of vegetation and evidence of past and current slope <br /> failures. <br /> 7. Western Project Area. View from bottom to top depicting <br /> steepness of slope, surface erosion and failure potential. <br /> 8, 9. Western Project Area. Views east at base of project area <br /> adjacent to 001 pond inlet ditch. Coal Creek is about twenty five <br /> feet lower in elevation and about twenty feet to the left (north) . <br /> Note cribbing failure in slide 8, and slumpage toward ditch in <br /> slide 9. <br /> 10, 11. Eastern Project Area. Note steepness of slope and <br /> surficial failures in these slides. Coal creek is further to the <br /> north in this area, adjacent to the road visible in slide 11. <br /> C:\wp51\midc\bids\orpeast <br />
