(d) The size of area to be worked at one time. <br /> The submission of this application is for a total of 43.25 Involved Acres. Of those acres, <br /> 27.59 acres contain mineable deposits of construction material.The existing approved 110c <br /> permit is currently for 9.8 acres.This is an increase in area of 17.79 acres of mineable alluvial <br /> deposits. <br /> Soil survey results for the property,as previously supplied in Exhibit C,Subsection H, indicate <br /> that the mineable material is classified as; Ellicott-Glenberg complex,0 to 3 percent slopes. <br /> Material profile of such classification are as follows <br /> Typical profile <br /> A-0 to 4 inches:sand <br /> AC-4 to 13 inches: sand <br /> C1- 13 to 30 inches: sand <br /> C2-30 to 44 inches: sand <br /> C3-44 to 80 inches: coarse sand. <br /> Profile indicates that fine sand is nearer the surface and material coarseness increases with <br /> depth as is typical of stream bed deposits. Our client base varies considerably in the type of <br /> material they are interested in.Two of which are only interested in fine sand meeting the <br /> gradation of masonry sand.This material is generally found only in the top layers of material. <br /> As we continue to mine the permit approved 9.8 acres in the original 110c permit,that <br /> material is becoming less abundant. A phased approach of mining and reclamation is outlined <br /> within this application, based upon depth of completed mining with an approximate timeline. <br /> As a result,any one of the mineable acres and strata may be worked at any one time. <br /> Within the boundaries of the mineable area,the creek courses around several hills.The <br /> mining plan has been developed such that mining will be conducted as in the examples <br /> below. Reclamation of the outer creek bank to a 3:1 slope is impractical and currently does <br /> not exist in most of the area within the drainage,other than the creek bed itself. <br />
