3. Natural vegetation shall be restored insofar as feasible after any construction project is completed <br />to retard surface runoff and soil erosion. <br /> 4. The provisions of this section shall not apply to permitted uses which normally require the <br />removal of natural vegetation. <br /> (2) Topographic alterations/grading and filling. <br /> (a) Grading, filling and excavations necessary for the construction of structures, sewage treatment <br />systems, driveways and other uses permitted in the underlying zoning district under validly issued <br />construction permits for these facilities do not require the issuance of a separate grading and filling permit. <br />However, the grading and filling standards in this section must be incorporated into the issuance of permits <br />for construction of structures, sewage treatment systems and driveways. <br /> (b) Public roads and parking areas are regulated by division (3) of this chapter. <br /> (c) Notwithstanding divisions (2)(a) and (2)(b) above, a grading and-filling permit, in accordance with <br />the City Zoning Chapter, will be required for: <br /> 1. The movement of more than ten cubic yards of material on steep slopes or within the shore impact <br />zone; or <br /> 2. The movement of more than 50 cubic yards of material per acre. <br /> (d) The following considerations and conditions must be adhered to during the issuance of <br />construction permits, grading and filling permits, conditional use permits, variances and subdivision <br />approvals: <br /> 1. Grading or filling in any wetland must be evaluated to determine the extent of impact to the <br />functions and values of the wetland area in accordance with the city code. This evaluation must also include <br />a determination of whether the wetland alteration being proposed requires permits, reviews or approvals by <br />other local, state or federal agencies such as a watershed district, a local governmental unit, the Minnesota <br />Department of Natural Resources or the United States Army Corps of Engineers. The applicant will be so <br />advised. <br /> 2. Alterations must be designed and conducted in a manner that ensures only the smallest amount of <br />bare ground is exposed for the shortest time possible. Mulches or similar materials must be used, where <br />necessary, for temporary bare soil coverage and a permanent vegetation cover must be established as soon <br />as possible; <br /> 3. Methods to minimize soil erosion and to trap sediments before they reach any surface water <br />feature must be used. Altered areas must be stabilized to acceptable erosion control standards consistent <br />with the field office technical guides of the Anoka County Soil and Water Conservation District and the <br />United States Soil Conservation Service; <br /> 4. Fill or excavated material must not be placed in a manner that creates an unstable slope. Plans to <br />place fill or excavated material on steep slopes must be reviewed by qualified professionals for continued <br />slope stability and must not create finished sloped of 30% or greater; <br /> 5. Any alterations below the ordinary high water level of the waterbodies described in § 1002.05(1) <br />must first be authorized by the Commissioner under M.S. § 103G.245, as it may be amended from time to <br />time; <br /> 6. Alterations of topography must only be allowed if they are necessary to allow a defined permitted <br />accessory or conditional use within the underlying zoning district and do not adversely affect adjacent or <br />nearby properties; and <br /> 7. Placement of natural rock riprap, including associated grading of the shoreline and placement of a <br />filter blanket, is permitted if the finished slope does not exceed three feet horizontal to one foot vertical, the
