ARTICLE VIII. FLOODPLAIN MANAGEMENT* Page 3 of 5 <br /> (5) Storage of materials and equipment. <br /> a. 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 /> b. 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 /> (6) The provisions of section 78-1122 of this article shall also apply. <br /> � Sec. 78-1122. Standards for all flood fringe uses. � <br /> (a) All new principal structures must have vehicular access at or above an elevation not more <br /> than two feet below the regulatory flood protection elevation. If a variance to this requirement is <br /> granted, the city council must specify limitations on the period of use or occupancy of the <br /> structure for times of flooding and only after determining that adequate flood warning time and <br /> local flood emergency response procedures exist. <br /> (b) Commercial uses. Accessory land uses, such as yards, railroad tracks, and parking lots <br /> may be at elevations lower than the regulatory flood protection elevation. However, a permit for <br /> such facilities to be used by the employees or the general public shall not be granted in the <br /> absence of a flood warning system that provides adequate time for evacuation if the area would <br /> be inundated to a depth and velocity such that when multiplying the depth (in feet) times velocity <br /> (in feet per second) the product numberexceeds four upon occurrence of the regional flood. <br /> � (c) Manufacturing and industrial uses. Measures shall be taken to minimize interference with <br /> normal plant operations especially along streams having protracted flood durations. Certain <br /> accessory land uses such as yards and parking lots may be at lower elevations subject to <br /> requirements set out in section 78-1122(b) above. In considering permit applications, due <br /> � consideration shall be given to needs of an industry whose business requires that it be located <br /> in flood plain areas. <br /> (d) Fill shall be properly compacted and the slopes shall be properly protected by the use of <br /> riprap, vegetative cover or other acceptable method. The Federal Emergency Management <br /> Agency (FEMA) has established criteria for removing the special flood hazard area designation <br /> for certain structures properly elevated on fill above the 100-year flood elevation--FEMA's <br /> requirements incorporate specific fill compaction and side slope protection standards for multi- <br /> structure or multi-lot developments. These standards should be investigated prior to the <br /> initiation of site preparation if a change of special flood hazard area designation will be <br /> requested. <br /> (e) Flood plain developments shall not adversely affect the hydraulic capacity of the channel <br /> and adjoining flood plain of any tributary watercourse or drainage system where a floodway or <br /> other encroachment limit has not been specified on the official floodplain overlay district map. <br /> (fl Standards for recreational vehicles are contained in section 78-1131. <br /> (g) All manufactured homes must be securely anchored to an adequately anchored foundation <br /> system that resists flotation, collapse and lateral movement. Methods of anchoring may include, <br /> but are not to be limited to, use of over-the-top or frame ties to ground anchors. This <br /> requirement is in addition to applicable state or local anchoring requirements for resisting wind <br /> � forces. <br /> DIVISION 6.
