<br /> <br /> <br />' The r•eclantation sequence in the Upland area is as followsf <br />1. Rough dr•ade. <br />' 'c'. Install topsoil and grade out. <br />3. 6ri1t seed as war•nt season cover crop in sor•ina. <br />4. Dr•ili seed the permanent grass in fall. <br />' 3. Cattle to be fenced off until atletluate dr•ass cover is <br />established. <br />E. Reseed grasses where necessary. <br />In the Lowland area the Creek 6ott~~m will be r•e-established t>~ <br />operate not ur•al ly as it does now. The slde slopes will be <br />vegetated quickly and the slopes will be no ntor•e than ?:1. In <br />' pr•ocr•ess reclantat ion will ntininti ze the amount of disturbed ground <br />upstr•eant of the mining pond as it mc+ves downstr•eant. Three feet <br />of rciateriat wilt be spread in the Creek. bottom. This material <br />' will be a result of r•e,7ect materials, clays, and silts. This <br />laye~r• of sands and soil wilt act as the alluvial water layer and <br />be the root zone for the establishment of trees. The Creek <br />itself will be lowered an average of twelve feet in the r•eclainted <br />' state. Re ter to Plate E-c for- a cross section of the new Creek <br />bottom. <br />' At the downstr•eant end of the mining, a channel wi 11 be made to <br />drain water out of the last mining pond. to this way no stantlino <br />water- wi 11 be left antl water- wi 11 not evaporate in the long ter•nt. <br />' The channel itself will have a flatter- slope than the Creek. <br />bottom. In this way the channel can daylight out to the existing <br />grade at approximately laaa feet upstream of the East Quincy <br />Flvenue bridge. See Plate £-3 for- a standar^d cross section. This <br />' channel cross section will carry appr•ox intately the 10~D-year storm <br />event. <br />' Trees will be planted in the new Cr^eek bottom. Generally these <br />trees will be planted in large groups at the upstream sides oP~ <br />land pr•otr•usion5. In this way the trees groups can stabilize the <br />' ground front erosion in high (tows. Tree groups can also divert <br />water- back front the side slopes into the ntiddie of the Creek <br />bottom. These tree groups will also serve as anlntai habitat. <br />See Plate E-4 for a typical tree or•oup planting. <br />' Several locations of ntinor• tributaries Plow into Coat Creek. <br />Gener•alty these tributaries only flow during nta,7or rains. <br />' Nonetheless they must be preserved front erosion and headcutting. <br />Plate E-5 shows the use of logs and r•u661e to prevent erosion. <br />Mayor tributaries and Coal Creek itself at the upstream end of <br />the mining will require greater armoring.
