The regulatory flood protection elevation within the fioodway and flood fringe districts, <br /> 18 except for Lake Minnetonka,shall be established by adding 1.0 foot to the base flood water <br /> 19 surface elevations within floodway listed in the floodway data table contained in the flood <br /> 20 insurance study. Regulatory flood protection elevations between cross sections shall be <br /> 21 interpolated. <br /> 22 b. The regulatory flood protection elevation for Lake Minnetonka shall be 932.5 MSI. <br /> 23 c. The regulatory flood protection elevation within the general floodplain district shall be <br /> 24 calculated by a qualified registered professional engineer in accordance with procedures set forth <br /> 25 in this article. <br /> 26 Repetitive Loss: Flood related damages sustained by a structure on two separate occasions during a ten year period <br /> 27 for which the cost of repairs at the time of each such flood event on the average equals or exceeds 25%of the <br /> 28 market value of the structure before the damage occurred. <br /> 29 Special Flood Hazard Area—a term used for flood insurance purposes synonymous with "One Hundred Year <br /> 30 Floodplain." <br /> 31 Start of Construction—includes substantial improvement,and means the actual start of construction, repair, <br /> 32 reconstruction, rehabilitation,addition, placement or other improvement that occurred before the permit's <br /> 33 expiration date.The actual start is either the first placement of permanent construction of a structure on a site, <br /> 34 such as the pouring of slab or footings,the installation of piles,the construction of columns, or any work beyond <br /> 35 the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construction does <br /> 36 not include land preparation,such as clearing,grading and filling; nor does it include the installation of streets <br /> 37 and/or walkways; nor does it include excavation for a basement,footings, piers,foundations,or the erection of <br /> 38 temporary forms; nor does it include the installation on the property of accessory buildings,such as garages or <br /> 39 sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement,the actual <br /> 40 start of construction means the first alteration of any wall,ceiling,floor,or other structural part of a building, <br /> 41 whether or not that alteration affects the external dimensions of the building. <br /> 42 Structure-anything constructed or erected on the ground or attached to the ground or on-site utilities, including, <br /> 43 but not limited to, buildings,factories,sheds,detached garages,cabins, manufactured homes, recreational vehicles <br /> 44 not meeting the exemption criteria specified in Section 78-1137(2)of this ordinance and other similar items. <br /> Flood Plain Ordinance <br /> Page 4 <br />
