Page 17 <br /> 6.4.12 EXHIBIT L - Reclamation Costs <br /> Soil Demand AND Re-soiling of Affected Lands (refer to Exhibit D): <br /> Soil demand is limited to the cut basin slopes remaining above the static water level. For <br /> Central Field, the total area above the anticipated static water level of the basins is 11.82± <br /> acres. <br /> To estimate the area involved in resoiling the Center Section of Central Field — we'll use <br /> a percentage of the total perimeter length of the extraction limits involved: <br /> 15,074.72 Total perimeter length Central Field <br /> 1,633.27 Perimeter length Center—Central Field—extraction limits along WCR 396 <br /> 6,243.23 Perimeter length Center—Central Field—extraction limits along S.
