The location of the slope analyzed in this document was chosen by its proximity to the <br /> offsite structures in question. As the figure below shows, it is a cross section on the east end of <br /> the site,where reclamation backfilling and grading is complete. Other locations along the <br /> railroad tracks have slope crests farther from neighboring structures. Additionally,those slopes <br /> are shorter in height(10-15 feet tall)than the chosen slope(20-25 feet tall). Failure on a taller <br /> slope will lay the top of the failure circle farther up the slope. <br /> r # <br /> l ,y <br /> f" <br /> f <br /> Figure 1 —Slope Stability Cross Section Location <br /> Orchard Grove Slope Stability 1 Grey Lawicki 11,.--.-1 <br /> L1.1 <br />
