• appendix B to this PSR. As shown on the site Preliminary Closure <br /> Plan drawings, the final cover for the landfill will include a <br /> vegetative layer. This soil layer will be planted with a drought <br /> and erosion resistant grass. This grass will be "Blando Bromme" or <br /> a similar species, which will require fertilization but will not <br /> require irrigation. Details on the vegetation plan for the site <br /> will be developed in the future when the Final Closure Plan for the <br /> site is developed. <br /> H. Site life: <br /> Estimates of waste capacity, earthwork, soil cover requirements, <br /> and site life according to the RDSI for the landfill are shown in <br /> Table 1. The in-place refuse capacity for the site is 102 , 116, 000 <br /> cubic yards of compacted landfilled waste including daily cover <br /> material. These quantities were calculated using Softdesk Civil <br /> Engineering software and Autocad. Table 2 shows the projected <br /> annual waste quantities based on the actual waste quantity received <br /> at the site for 1994, and assuming a 5 percent annual growth rate <br /> in waste quantities to be received over time (This 5% annual <br /> percentage rate figure was obtained using County solid waste <br /> records) . A list of assumptions used follows the table. <br /> Sheet 3 of the Preliminary Closure Plan drawings shows the <br /> sequential waste management units (modules) which make up the <br /> landfill. The total service life for all 29 modules and the <br /> • <br /> existing landfill area is approximately 61 years, or until the end <br /> of 2055. <br /> I. Planning for future use after closure: <br /> Planning for future use after closure will be addressed in the <br /> future when a final closure plan is developed for the landfill. <br /> II. SUMMARY <br /> A. Land development consideration: <br /> General Land Use in the area of the Foothill Sanitary Landfill is <br /> classified as Agricultural according to the General Plan for San <br /> Joaquin County. The land is gently rolling hills generally used <br /> for grazing. The soil types on the site, according to a soil <br /> survey performed by the United States Soil Conservation Service in <br /> October 1988, are classified as Class VI and VII soils which are <br /> non-irrigated and suited primarily to use as rangeland. <br /> The remoteness and agricultural setting of the site, which is <br /> limited--f— �'grazing, minimizes impacts of the landfill on <br /> surrounding land use. The Preliminary Closure Plan proposes gentle <br /> slopes which meet all current regulations and match the existing <br /> • topography of the area. <br /> 7 <br />
