S. Standard <br /> sieve; <br /> (c) A gradation series (i.e., well-graded) that is amenable to compaction; and <br /> 2) A nonwoven bottom geotextile, which may be part of the geosynthetic clay layer(GCL). <br /> 3) A GCL that shall exhibit appropriate strength characteristics (hydrated) to accommodate <br /> stresses associated with specific landfill design parameters, with particular attention to <br /> interface, long-term creep shear, and bearing capacity. <br /> 4) A 60-mil thick synthetic flexible membrane of HDPE. <br /> 5) 0.75-foot-thick gravel drainage layer on base areas with a hydraulic conductivity greater <br /> than 0.1 cm/sec. <br /> 6) A filter geotextile. <br /> c. The side slope liner shall be comprised, in ascending order, of the following: <br /> 1) A prepared subgrade that meets the criteria contained in Construction Specification D.4, <br /> below. <br /> 2) A GCL barrier that shall exhibit appropriate strength characteristics to accommodate ' <br /> stresses associated with specific landfill design parameters, with particular attention to <br /> interface, long-term creep shear, and bearing capacity. <br /> 3) A 60-mil thick synthetic flexible primary membrane of HDPE. <br /> 4) A geocomposite drainage layer. <br /> 5) A filter geotextile. <br /> 6) A two-foot thick soil operations layer. <br /> The County is required to address this issue by supplementing the R®WD with the appropriate citations, <br /> figures, etc. Please ensure the new inserts are dated in the footer of each page/drawing. <br />
