Additional structure setbacks. The following additional structure setbacks apply, 4 regardless of the classification of the water body: Setback From: Setback in feet Top of bluff 30 Un latted cemetery 50 Right-of-way line of federal, state, or county highway 50 Right-of-way line of town road, public street, or other roads or streets not 20 classified 5 6 C. Bluff impact zones. Structures and accessory facilities, except stairways and landings, 7 must not be placed within bluff impact zones. 8 d. Uses without water-oriented needs. Uses without water-oriented needs must be located 9 on lots or parcels without public waters frontage, or, if located on lots or parcels with 10 public waters frontage, must either be set back double the normal ordinary high water 11 level setback or be substantially screened from view from the water by vegetation or 12 topography, assuming summer, leaf-on conditions. 13 (2) Design criteria for structures. 14 a. High water elevations. Structures must be placed in accordance with any floodplain 15 regulations applicable to the site. Where these controls do not exist, the elevation to 16 which the lowest floor, including basement, is placed or floodproofed must be 17 determined as follows: 18 1. For lakes,by placing the lowest floor at a level at least three feet above the highest 19 known water level, or three feet above the ordinary high water level, whichever is 20 higher; 21 2. For rivers and streams, by placing the lowest floor at least three feet above the 22 flood of record, if data are available. If data are not available,by placing the lowest 23 floor at least three feet above the ordinary high water level, or by conducting a 24 technical evaluation to determine effects of proposed construction upon flood 25 stages and flood flows and to establish a flood protection elevation.Under all three 26 approaches, technical evaluations must be done by a qualified engineer or 27 hydrologist consistent with Minn.Rules pts. 6120.5000-6120.6200 governing the 28 management of floodplain areas. If more than one approach is used, the highest 29 flood protection elevation determined must be used for placing structures and other 30 facilities; and 31 3. Water-oriented accessory structures may have the lowest floor placed lower than 32 the elevation determined in this item if the structure is constructed of flood- 33 resistant materials to the elevation, electrical and mechanical equipment is placed 34 above the elevation and, if long duration flooding is anticipated, the structure is 35 built to withstand ice action and wind-driven waves and debris. 36 b. Water-oriented accessory structures. Each lot may have one water-oriented accessory 37 structure not meeting the normal structure setback in this subdivision if this water- 38 oriented accessory structure complies with the following provisions: Page 121 of 141
