The field data was <br />compared to cross-sections taken from the final reclamation map. The estimate <br />indicates that approximately 7,400 loose cubic yards of material would have to <br />be moved to achieve the approved final confiDUration, Cross-section sketches <br />and approximate locations are shown on the attached oases. The check appears <br />to indicate that a material deficit may exist for the proposed 3:1 final <br />grade. An accurate survey based map of the existing topography should be <br />prepared to verify the feasibility of the final topography. <br />DTtA/yj b <br />2774E <br />
