Uses without <br />710 water -oriented needs must be located on lots or parcels <br />711 without public waters frontage, or, if located on lots or parcels <br />712 with public waters frontage, must either be set back double <br />713 the normal ordinary high water level setback or be <br />714 substantially screened from view from the water by vegetation <br />715 or topography, assuming summer, leaf -on conditions. <br />716 <br />717 <br />718 <br />719 <br />720 <br />721 <br />722 <br />723 <br />724 <br />725 <br />726 <br />727 <br />728 <br />729 <br />730 <br />731 <br />732 <br />733 <br />734 <br />735 <br />736 <br />737 <br />738 <br />739 <br />740 <br />741 <br />742 <br />743 <br />744 <br />745 <br />746 <br />747 <br />{3b. Design criteria for structures. <br />a1. High water elevations. Structures must be placed in accordance with <br />any floodplain regulations applicable to the site. Where these controls <br />do not exist, the elevation to which the lowest floor, including <br />basement, is placed or floodproofed must be determined as follows: <br />i. For lakes, by placing the lowest floor at a level at least three <br />feet above the highest known water level, or three feet above <br />the ordinary high water level, whichever is higher; <br />ii. For rivers and streams, by placing the lowest floor at least <br />three feet above the flood of record, if data are available. If <br />data are not available, by placing the lowest floor at least <br />three feet above the ordinary high water level, or by <br />conducting a technical evaluation to determine effects of <br />proposed construction upon flood stages and flood flows and <br />to establish a flood protection elevation. Under all three <br />approaches, technical evaluations must be done by a <br />qualified engineer or hydrologist consistent with Minn. Rules <br />pts. 6120.5000-6120.6200 governing the management of <br />floodplain areas. If more than one approach is used, the <br />highest flood protection elevation determined must be used <br />for placing structures and other facilities; and <br />iii. Water -oriented accessory structures may have the lowest <br />floor placed lower than the elevation determined in this item if <br />the structure is constructed of flood -resistant materials to the <br />elevation, electrical and mechanical equipment is placed <br />above the elevation and, if long duration flooding is <br />anticipated, the structure is built to withstand ice action and <br />wind -driven waves and debris. <br />�2. Water -oriented accessory structures. Each lot may have one water - <br />oriented accessory structure not meeting the normal structure <br />21 <br />I Formatted: Font: Not Italic <br />Formatted: Indent: Left: 2", Hanging: 0.5 , <br />No bullets or numbering <br />Formatted: Indent: Left: 1", Hanging: 0.5 1 <br />
