• ARTICLE VIII. FLOODPLAIN MANAGEMENT* Page 3 of 3 <br /> for parking of vehicles and limited storage. All flood proofed accessory structures must <br /> meet the following additional standards: <br /> a. The structure must be adequately anchored to prevent flotation, collapse or <br /> lateral movement of the structure and shall be designed to equalize hydrostatic <br /> flood forces on exterior walls; <br /> b. Any mechanical and utility equipment in a structure must be elevated to or � <br /> above the regulatory flood protection elevation or properly flood proofed; and <br /> c. To allow for the equalization of hydrostatic pressure, there must be a <br /> minimum of two "automatic" openings in the outside walls of the structure having <br /> a total net area of not less than one square inch for every square foot of enclosed <br /> area subject to flooding. There must be openings on at least two sides of the <br /> structure and the bottom of all openings must be no higher than one foot above <br /> the lowest adjacent grade to the structure. Using human intervention to open a <br /> garage door prior to flooding will not satisfy this requirement for automatic <br /> openings. <br /> (fl Storage of materials and equipment. <br /> 1. The storage or processing of materials that are, in time of flooding, flammable, <br /> explosive, or potentially injurious to human, animal, or plant life is prohibited. <br /> 2. Storage of other materials or equipment may be allowed if readily removable from <br /> the area within the time available after a flood warning and in accordance with a plan <br /> approved by the city council. <br /> � (g) Flood control. Structural works for flood control that will change the course, current or cross <br /> section of protected wetlands or public waters shall be subject to the provisions of Minn. Stat. <br /> ch. 103G. Community-wide structural works for flood control intended to remove areas from the <br /> : . . .. , regulatory flood plain shall not be allowed in the floodway. <br /> (h) A levee, dike or floodwall constructed in the floodway shall not cause an increase to the <br /> 100-year or regional flood and the technical analysis must assume equal conveyance or storage <br /> loss on both sides of a stream. <br /> http://library3.municode.com/default/DocView/13094/1/109/117 2/13/2008 <br />
