* This evaluation shall also include a determination of whether the wetland alteration being proposed requires permits, reviews, or approvals by other local, state, or federal agencies such as the Minnehaha Creek Watershed District, the Minnesota Department of Natural Resources, or the United States Army Corps of Engineers. The applicant shall be so advised. b) Alterations shall be designed and conducted in a manner that ensures only the smallest amount of bare ground is exposed for the shortest time possible; c) Mulches or similar materials shall be used, where necessary, for temporary bare soil coverage, and permanent vegetation cover shall be established as soon as possible. d) Methods to minimize soil erosion and to trap sediments before they reach any surface water feature shall be used; e) Altered areas shall be stabilized to acceptable erosion control standards consistent with the field office technical guides of the local soil and water conservation districts and the United States Soil Conservation Service; f) Fill or excavation material shall not be placed in a manner that creates an unstable slope; g) Plans to place fill or excavate material on steep slopes shall be reviewed by qualified professionals for continued slope stability and shall not create finished slopes of 30 or greater; h) Fill or excavated material shall not be placed in bluff impact zones; i) Any alterations below the ordinary high water level of public waters shall first be authorized by the Commissioner under Minn. Stats. § 105.42. j) Alterations of topography shall only be allowed if they are accessory to permitted or conditional uses and shall not adversely affect adjacent or nearby properties; and k) Placement of natural rock riprap, including associated grading of the shoreline and placement of a filter blanket, shall be permitted if the finished slope does not exceed three feet horizontal to one foot vertical, and the landward extent of the riprap is within ten feet of the ordinary high water level, and the height of the riprap above the ordinary high water level does not exceed three feet. 4. Connections to Public Waters. Excavation where the intended purpose is connection to a public water, such as boat slips, canals, lagoons, and harbors, shall be controlled by local shoreland controls. Permission for excavations may be given only after the Commissioner has approved the proposed connection to public waters. C. Placement and Design of Roads, Driveways, and Parking Areas. 1. Public and private roads and parking areas shall be designed to take advantage of natural vegetation and topography to achieve maximum screening from view from public waters. Documentation shall be provided by a qualified individual that all roads and parking areas are designed and constructed to minimize and control erosion to public waters consistent with the guidelines of the Minnehaha Creek Watershed District. 2. Roads, driveways, and parking areas shall meet structure setbacks and shall not be placed within bluff and shore impact zones, when other reasonable and feasible placement alternatives exist. If no alternatives exist, they may be placed within these areas, and shall be designed to minimize adverse impacts. 3. Public and private watercraft access ramps, approach roads, and access-related parking areas shall be placed within shore impact zones provided the vegetative screening and erosion control conditions of this sub-part are met. For private facilities, the grading and filling provisions of Section 991.14.6 of this Ordinance shall be met.
