Note: Once the volume for the Upper slopes to meet a 311:1V configuration was <br /> determined, the volume necessary to meet the underlying 3H:1V slopes below it <br /> was needed. The extent of these slopes extends from a green line at the top of <br /> the 3H:1V slopes to the apx. bottom of the basin shown with an Orange Hatch. <br /> The resulting volumes and correlated calculations are shown on the included <br /> Chart. The results show an additional 210,155.86 cu.yds. of fill are needed to <br /> bring slopes to a reclaimed grade for both Tracts C and D. Utilizing comparative <br /> figures from the 10 June 2011 OMLR Grading estimate (included with this <br /> submittal), a total warranty to cover the basin grading is $155,165.12. <br /> Other Information: <br /> 1. Backfilling of the basin slopes will continue until the basin area is equal to <br /> or less than the extents shown on the included map. <br /> 2. Water elevation is at 4616', as shown by a Cyan colored line on the <br /> included map. <br /> 3. The yellow triangle outside the northwest corner of the permit area is not <br /> part of the existing permit. <br /> 4. <br /> -fin- <br /> cc. Garrett C.
