14. <br /> <br />15. <br /> <br />16. <br /> <br />well is located approximately 500 feet from the boundary of the mining area. It is not <br />anticipated that the well will be affected by the mining operation, as no new wells are <br />planned and the mining is not expected to disturb the underlying aquifer. All mining will <br />occur at least five feet above the water table. <br /> <br />Water-Related Land Use Management District: <br /> <br />Does any part of the project involve a shoreland zoning district, a delineated 100- <br />year flood plain, or a state or federally designated wild or scenic river land use <br />district? Yes X No <br /> <br />If yes, identify the district and discuss project compatibility with district land use <br />restrictions. <br /> <br />Water Surface Use: <br /> <br />Will the project change the number or type of watercraft on any water body? <br />BYes ~X No <br /> <br />If yes, indicate the current and projected watercraft usage and discuss any potential <br />overcrowding or conflicts with other uses. <br /> <br />Erosion and Sedimentation: <br /> <br />Give the acreage to be graded or excavated and the cubic yards of soil to be moved: <br />Approximately 14.81 acres; 500~000 cubic yards. <br /> <br />Describe any steep slopes or highly erodible soils and identify them on the site map. <br />Describe any erosion and sedimentation control measures to be used during and <br />after project construction. <br /> <br />The mining operation will not involve the creation of any steep slopes. The nature of the <br />Site is unique, in that the gravel resources to be mined are located only in long narrow <br />ridges (eskers). It is anticipated that these ridges will be excavated and removed, leaving <br />a relatively flat landscape behind. Once removed, only minimal excavation will occur <br />below the ridges. Based on the topographic contours of the Site, surface water runoff <br />from the eastern portion of the Site will flow to the east. Surface water runoff from the <br />western portion of the Site will remain on site and flow into the low areas or wetlands. <br /> <br />Surface water runoff and erosion controls are proposed to control surface water discharge <br />off site. The proposed controls will include installation of silt fence/hay bales, rip-rap <br />placement in drainageways, and phased topsoil replacement and seeding of completed <br />phases. The silt fence/hay bales and rip-rap will be placed in areas deemed necessary <br />during mining operations. Since most of the Site will remain undisturbed during the <br />mining operations, only minimal, if any, off site surface water run off is anticipated. <br /> <br /> LIESCH ASSOCIATES, INC. <br />Hydrogeologists · Engineers · Environmental Scientists <br /> <br />· Jan-2003 · · Page 9 · <br /> <br /> <br />
