Grading and filling and excavations necessary for the construction of structures, sewage <br /> 6 treatment systems, and driveways under validly issued construction permits for these <br /> 7 facilities do not require the issuance of a separate grading and filling permit. However, the <br /> 8 grading and filling standards in this subdivision must be incorporated into the issuance of <br /> 9 permits for construction of structures, sewage treatment systems, and driveways. <br /> 10 b. Public roads and parking areas are regulated by this subdivision. <br /> 11 c. Notwithstanding subsections (g)(2)a and b of this section, a grading and filling permit will be <br /> 12 required for: <br /> 13 1. The movement of more than ten cubic yards of material on steep slopes or within shore <br /> 14 or bluff impact zones; and <br /> 15 2. The movement of more than 50 cubic yards of material outside of steep slopes and shore <br /> 16 and bluff impact zones. <br /> 17 d. The following considerations and conditions must be adhered to during the issuance of <br /> 18 construction permits, grading and filling permits, conditional use permits, variances and <br /> 19 subdivision approvals: <br /> 20 1. Grading or filling in any type 2, 3,4, 5, 6, 7, or8wetland must be evaluated to determine <br /> 21 how extensively the proposed activity would affect the following functional qualities of <br /> 22 the wetland. This evaluation must also include a determination of whether the wetland <br /> 23 alteration being proposed requires permits, reviews,or approvals by other local, state,or <br /> 24 federal agencies such as a watershed district, the state department of natural resources, <br /> 25 or the United States Army Corps of Engineers.The applicant will be so advised. <br /> 26 (i) Sediment and pollutant trapping and retention; <br /> 27 (ii) Storage of surface runoff to prevent or reduce flood damage; <br /> 28 (iii) Fish and wildlife habitat; <br /> 29 (iv) Recreational use; <br /> 30 (v) Shoreline or bank stabilization; and <br /> 31 (vi) Noteworthiness, including special qualities such as historic significance, critical <br /> 32 habitat for endangered plants and animals, or others. <br /> 33 2. Alterations must be designed and conducted in a manner that ensures only the smallest <br /> 34 amount of bare ground is exposed for the shortest time possible; <br /> 35 3. Mulches or similar materials must be used, where necessary, for temporary bare soil <br /> 36 coverage, and a permanent vegetation cover must be established as soon as possible; <br /> 37 4. Methods to minimize soil erosion and to trap sediments before they reach any surface <br /> 38 water feature must be used; <br /> 39 5. Altered areas must be stabilized to acceptable erosion control standards consistent with <br /> 40 the field office technical guides of the local soil and water conservation districts and the <br /> 41 United States Soil Conservation Service; <br /> 42 6. Fill or excavated material must not be placed in a manner that creates an unstable slope; <br /> 43 7. Plans to place fill or excavated material on steep slopes must be reviewed by qualified <br /> 44 professionals for continued slope stability and must not create finished slopes of 30 <br /> 45 percent or greater; <br /> 46 8. Fill or excavated material must not be placed in bluff impact zones; <br /> 47 9. Any alterations below the ordinary high water level of public waters must first be <br /> 48 authorized by the commissioner under Minn. Stats. § 103G.245; <br /> Page 128 of 147 <br />
