RECLAMATION PLAN <br />Furthermore, where the gravel merges with adjacent land that does NOT contain <br />gravel there are no steep slope situations produced except on the south <br />boundary of the permit where the upper gravel layer is removed. Only in that <br />area does slope gradient became a concern. <br />Along the south boundary of the operation the procedure will be to mine <br />an essentially vertical face up to 25 feet from the property boundary. This <br />allows for sane leeway in case the face collapses. A slope would then be <br />created using waste material, subsoils, and finally topsoil. The final slope <br />would have a maximum gradient of 3:1. The fill would then 6e revegetated. <br />This procedure should prevent any damage to adjacent land and produce an <br />excellent north facing slope with a length of about 30 to 40 feet <br />(horizontally). <br />WATER: Water control an this site will be a simple matter. First, there is <br />no ground water that will require special consideration. Second, runoff from <br />this land is gradual and occurs along shallow slopes. High velocity flows <br />simply could not develop except on the swath end where the slopes of the hills <br />are somewhat steeper, In this area, erosional damages in the past as a result <br />of severe and very heavy thunderstorms has not occurred. In part, this is due <br />to short slopes, but the soil cover composed largely of gravel and cobbles <br />also helps control erosion so gullies do not occur. <br />No streams occur on the site. Therefore, diversions and catchments are <br />unnecessary. Dredge and fill permits and discharge permits are not needed. <br />However, where denuded land occurs upslope from vegetated land, runoff can <br />induce erosion and sedimentation. <br />On shallow slopes and nearly level land, experience has shown the best <br />way to control this runoff so adjacent vegetation is not harmed is to control <br />the water within the excavation area, Catchment basins are useful where <br />discrete channels occur, but in a situation such as this where sheet flow will <br />be the most common pattern, catchment basins do little good. It is better to <br />keep the surface rough along the contour, similar to contour plowing in crop <br />field management. The contour ridges capture water like very small catchment <br />basins. This approach also has a tremendous benefit in maximizing the <br />utilization of precipitation to enhance revegetation. In winter, the contour <br />furrows catch snow rather than allowing it to blow further downwind to sane <br />. other parcel of land that may not need the moisture as much.
