CONTINENTAL MATERIALS CORPORATION <br /> Response: The maps included in Exhibits C and F show the borrow areas, and the maps have been <br /> revised to specify the volume of material available from each area. <br /> 44. Existing Scarp:The three sections analyzed in Exhibit 6.5 do not cover the existing limestone cap that <br /> remained in place after previous slides in 2008, 2009 and 2015. This scarp lies between cross-section Z-Z' <br /> and the Lower Borrow Area section shown on map Exhibit C-2. Please address the stability of this scarp <br /> and explain why it was not addressed in the stability analyses. <br /> Response: The cross-sections analyzed were drawn along the slope gradient through the landslide.The <br /> direction of movement above the scarp is not in perpendicular to the slope and a geotechnical analysis <br /> across the slope would provide results that are artificially high due to the apparently lower slope angles. <br /> Section Y-Y' in the center of the slide area has the lowest factors of safety, and this section controlled <br /> the geotechnical assessment and reclamation design.The slope gradients that stabilize Section Y-Y' were <br /> used for the entire slide area, which was specifically extended to the southernmost point of the scarp <br /> near at the toe of the slide to provide a buttress for the entire scarp.The extents of the buttress fill have <br /> been added to the maps in Exhibit C. <br /> Pikeview Quarry Amendment 4, Response to Adequacy <br /> February 7,2020 <br /> 15 <br />
