aOver the lifetime of a project, soil used to construct well pads, roads, and <br />other features can diminish in volume. Erosion and degradation of soil <br />tilth contribute to this loss. When contouring to match the surrounding <br />terrain, material from the original cut, combined with fill from a <br />previously undisturbed area may be required to construct an acceptable <br />new grade. Caution should be exercised when disturbing new areas. The <br />area disturbed should be kept to a minimum. Figure A2 shows a cross- <br />section of a road cut with a new grade and the source of material. Not <br />only is this applicable to a road cut: well pads and other structures may <br />use the same concept to match the surrounding land form. <br />Road Reclaim, Use of Cut and Fill Material <br />Previously Undisturbed, Mnew" Cut <br />New Grade <br />Original Cut Material <br />1` <br />M4..: rAda- <br />�rfnt yilfi4l $Fl4*Fu�wyu5ta' n :¢ A�n�f;� <br />Fiaure A2. An example of cut and fill to restore land form. <br />During the design of the cut and fill, one should identify areas where the <br />original cut material was placed with the intent of reuse for the contouring <br />process. <br />The matching of surface elevations should take into account the settling <br />of material that has been excavated and contoured to the surrounding <br />land form. If not using an engineered fill and compaction procedure, the <br />newly placed fill should be slightly higher then the non -disturbed areas to <br />531 Pa, <br />BY GRIA-1 1, WN l'�Y11t��N ill .ti IAL AND ACItIA I)( -.S - MV14SAI N 16A51N1 NS- 1'L.COM <br />
