EXHIBIT F - Reclamation Plan Map <br />Reclamation map <br />See the attached mine reclamation map (Exhibit F) showing the proposed final re-grading of all disturbed areas. The <br />Pierce North gravel pit is proposed to be reclaimed as an on-line stormwater detention and flood control structure to be <br />maintained by Weld County. The reclamation final grading with 3:1 side slopes will create an on-line detention pond <br />which will reduce flooding risk Lone Tree Creek downstream of the gravel pit site. <br />It is anticipated that the average thickness of overburden is minimal, however, overburden and excavated soil materials <br />unsuitable for road construction will be used to backfill excavated areas and for re-grading the site to stable slopes. <br />Stockpiled topsoil will be placed on re-graded areas prior to seeding with approved native grass seed mixes. <br />See Exhibit F. <br />MADAVE B\Pierce North\DMG permit\Exhibits-Revl.doc 8/21/2009
