1 (vi) Noteworthiness, including special qualities such as historic significance, 2 critical habitat for endangered plants and animals, or others. 3 2. Alterations must be designed and conducted in a manner that ensures only the 4 smallest amount of bare ground is exposed for the shortest time possible; 5 3. Mulches or similar materials must be used, where necessary, for temporary bare 6 soil coverage, and a peinianent vegetation cover must be established as soon as 7 possible; 8 4. Methods to minimize soil erosion and to trap sediments before they reach any 9 surface water feature must be used; 10 5. Altered areas must be stabilized to acceptable erosion control standards consistent 11 with the field office technical guides of the local soil and water conservation 12 districts and the United States Soil Conservation Service; 13 6. Fill or excavated material must not be placed in a manner that creates an unstable 14 slope; 15 7 Plans to place fill or excavated material on steep slopes must be reviewed by 16 qualified professionals for continued slope stability and must not create finished 17 slopes of 30 percent or greater; 18 8. Fill or excavated material must not be placed in bluff impact zones; 19 9. Any alterations below the ordinary high water level of public waters must first be 20 authorized by the commissioner under Minn. Stats. § 103G.245; 21 10. Alterations of topography must only be allowed if they are accessory to permitted 22 or conditional uses and do not adversely affect adjacent or nearby properties; and 23 11. Placement of natural rock rip -rap, including associated grading of the shoreline 24 and placement of a filter blanket, is permitted if the finished slope does not exceed 25 three feet horizontal to one foot vertical, the landward extent of the rip -rap is within 26 ten feet of the ordinary high water level, and the height of the rip -rap above the 27 ordinary high water level does not exceed three feet. 28 e. Connections to public waters. Excavations where the intended purpose is connection to 29 a public water, such as boat slips, canals, lagoons, and harbors, must be controlled by 30 local shoreland controls. Permission for excavations may be given only after the 31 commissioner has approved the proposed connection to public waters. 32 (3) Placement and design of roads, driveways, and parking areas. 33 a. Public and private roads and parking areas must be designed to take advantage of natural 34 vegetation and topography to achieve maximum screening from view from public waters. 35 Documentation must be provided by a qualified individual that all roads and parking 36 areas are designed and constructed to minimize and control erosion to public waters 37 consistent with the field office technical guides of the local soil and water conservation 38 district, or other applicable technical materials. 39 b. Roads, driveways, and parking areas must meet structure setbacks and must not be placed 40 within bluff and shore impact zones, when other reasonable and feasible placement 41 alternatives exist. If no alternatives exist, they may be placed within these areas, and 42 must be designed to minimize adverse impacts. 43 c. Public and private watercraft access ramps, approach roads, and access -related parking 44 areas may be placed within shore impact zones provided the vegetative screening and 45 erosion control conditions of this section are met. For private facilities, the grading and 46 filling provisions of subsection (g)(2) of this section must be met. 47 (4) Stormwater management. The following general and specific standards shall apply: 48 a. General standards: 49 1. When possible, existing natural drainageways, wetlands, and vegetated soil 50 surfaces must be used to convey, store, filter, and retain stoiniwater runoff before 51 discharge to public waters.
