• November 14, 1979 . Page 2 <br />2) Reclamation Plan <br />a. When will you start reclamation? <br />Reclamation will commence in April 1980 with the planting <br />of a screen row of willow trees along the west boundary of the washing <br />plant area. After that there will be no significant reclamation efforts <br />performed until Tract #1 has been fully excavated, estimated to be in <br />September 1982. At that time the excavated slopes will be finish graded, <br />topsoil placed and disced, and seed broadcast on the prepared land. <br />Willow and cottonwood trees will also be transplanted early the following <br />spring. The reclamation process will then proceed on a continuing basis <br />after each tract is excavated. <br />b. How many acres will be topsoiled, regraded and reseeded? <br />The affected land which will be reseeded consists of the <br />washing plant area and the slopes of the excavation area above the <br />anticipated elevation of the Lake which will be formed, and amounts to <br />17.15 acres. <br />c. When will you plant native cottonwood and willow, how many <br />will be planted, and where will you obtain the plant materials used? <br />The native cottonwood and willow trees will be planted in the <br />early spring before the growing season has started; it is anticipated to <br />plant approximately 300 trees in the washing plant area and along the <br />north and south perimeters of the excavation area above the potential <br />flood plain elevation. The trees will be transplanted for the most part <br />from seedlings which are presently growing at the site, and since the <br />masonry sand operation will be of some 24 years duration, most of the <br />trees should be of Large size by the time of completion. <br />d. How many acres will be reclaimed each year? <br />Reclamation efforts will be performed on one tract of the <br />excavation area at a time. With a tract being operated for a period of <br />2-1/2 to 3 years, the reclamation process will be phased to occur on a <br />three year cycle, with an average of one acre per tract being reclaimed <br />above the water surface at a time. The final reclamation effort on Tract <br />#8 and the washing plant area will involve approximately 13 acres. <br />e. What affect will the operation have on the downstream adjacent <br />Landowners? <br />The formation of a sediment free lake produces the possibility <br />that under flood conditions relatively clear water would leave the pit at the <br />downstream end and have a tendency to pick up sediment, thus causing <br />increased erosion in the downstream channel; however, a Larger area in <br />the pit will reduce the frequency of downstream flooding by delaying or <br />eliminating the lesser surface flows, A structure may be required in the <br />channel at the pit outlet to reduce erosion effects, depending upon what <br />groundwater Level is experienced and the actual excavation depth attained, <br />but there will be no impoundment of waters flowing through the acquifer. <br />
