Spinardi Associates <br /> 6.0 LANDSCAPING AND SCREENING <br /> The most visible portion of the mining operation is from the Blewett/Koster Road intersection. <br /> Adjacent neighbors are either mining operators (DSS) or agriculture. To visually soften the <br /> operation, RMC proposes a 50-foot setback along Blewett Road and the northern portion of <br /> Koster Road. Within this setback, RMC will construct a berm and plant irrigated trees. There <br /> will be RMC signs and directions for truckers. <br /> All other setbacks will be 25-feet except at the realigned Hospital Creek which will be 100-feet <br /> from the centerline of the creek to the top of mining. <br /> _ 7.0 RECLAMATION <br /> The project site upon completion of mining will be open space. The slopes will be backfilled to <br /> 2:1 and hydroseeded. Excess topsoil will be placed at the bottom of the pits to enhance <br /> vegetative growth. Phase I, IV and possibly Phase V, the silt ponds, will be capped to match the <br /> adjacent elevations. The other mined out pits will be 70 to 120 feet below the surface. The plant, <br /> office and other structures and objects will be removed and graded smooth. <br /> In accordance with the Surface Mining and Recovery Act (SMARA), the operator will prepare a <br /> cost estimate covering the costs of reclaiming the site. In addition the operator will provide the <br /> County with a financial assurance mechanism such as a surety bond for the amount of the cost of <br /> reclamation. <br /> — <br /> 8.0 TRAFFIC AND CERCULATION <br /> Access to and from the project site is from Koster Road. RMC would be interested in <br /> participating in a fund that would be used to construct an intersection at Interstate 5 and Blewett <br /> Road. Most likely there will need to be improvements to the Blewett and Koster Road <br /> intersection. <br /> 9.0 GEOTECHNICAL <br /> RMC has performed an extensive minerals exploration program on the site to determine the <br /> quality and quantity of aggregate contained in the subsurface and found it to contain adequate <br /> amounts of sand and gravel. They have hired the geotechnical firm of Geomatfix Consultants to <br /> perform a slope stability analysis on the temporary slopes of 3/4:1 and the final slopes of 2:1. <br /> — <br /> 4 <br />
