, �120.3300 Minnesota Rule Page 6 of 13 <br /> The placement of structures and other facilities on all lots must be managed by shoreland controls <br /> as follows: <br /> A. Structure setbacks. The following minimum setbacks presented in the following table <br /> for each class of public waters apply to all structures, except water-oriented accessory structures <br /> and facilities that are managed according to item H: <br /> (1) Structure setback standards <br /> Class Ordinary high water level setback (feet) Setback <br /> from top of <br /> bluff(feet) <br /> Unsewered Sewered <br /> Natural 150 150 30 <br /> environment <br /> Recreational 100 75 30 <br /> development <br /> General 75 50 30 <br /> development <br /> Remote river 200 200 30 <br /> segments <br /> Forested and 150 150 30 <br /> transition river <br /> segments <br /> Agricultural, urban, 100 50 30 <br /> and tributary river <br /> segments <br /> (2)Exceptions to structure setback standards in subitem (1). Where structures exist <br /> on the adjoining lots on both sides of a proposed building site, structure setbacks may be altered <br /> without a variance to conform to the adjoining setbacks provided the proposed building site is not <br /> located in a shore impact zone or in a bluff impact zone. <br /> B.High water elevations. In addition to the setback requirements of item A, local <br /> shoreland controls must regulate placement of structures in relation to high water elevation. <br /> Where state-approved, local flood plain management controls exist, structures must be placed at <br /> an elevation consistent with the controls. Where these controls do not exist, the elevation to which <br /> the lowest floor, including basement, is placed or flood-proofed must be determined as follows: <br /> (1)For lakes, by placing the lowest floor at a level at least three feet above the <br /> highest known water level, or three feet above the ordinary high water level, whichever is higher. <br /> In instances where lakes have a history of extreme water level fluctuations or have no outlet <br /> capable of keeping the lake level at or below a level three feet above the ordinary high water <br /> level, local controls may require structures to be placed higher. <br /> (2)For rivers and streams, by placing the lowest floor at least three feet above the <br /> flood of record, if data are available. If data are not available, by placing the lowest floor at least <br /> https://www.revisor.mn.gov/rules/?id=6120.3300 9/15/2011 <br />
