ii . Storage of other materials or equipment may <br /> • be allowed if readily removable from the area within <br /> the time available after a flood warning and in <br /> accordance with a plan approved by the City Council. <br /> F. The provisions of Section 902.08 (5) of this Ordinance <br /> shall also apply. <br /> 5. Standards for All Flood Fringe Uses. <br /> A. All new principal structures must have vehicular <br /> access at or above an elevation not more than two (2) feet <br /> below the Regulatory Flood Protection Elevation. If a <br /> variance to this requirement is granted, the Board of <br /> Adjustment must specify limitations on the period of use or <br /> occupancy of the structure for times of flooding and only <br /> 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, <br /> railroad tracks, and parking lots may be at elevations <br /> lower than the Regulatory Flood Protection Elevation. <br /> However, a permit for such facilities to be used by the <br /> employees or the general public shall not be granted in the <br /> absence of a flood warning system that provides adequate <br /> • time for evacuation if the area would be inundated to a <br /> depth greater than two feet or be subject to flood <br /> velocities greater than four feet per second upon <br /> occurrence of the regional flood. <br /> C. Manufacturing and Industrial Uses - Measures shall be <br /> taken to minimize interference with normal plant operations <br /> especially along streams having protracted flood durations. <br /> Certain accessory land uses such as yards and parking lots <br /> may be at lower elevations subject to requirements set out <br /> in Section 902. 08 (5) (B) above. In considering permit <br /> applications, due consideration shall be given to needs of <br /> an industry whose business requires that it be located in <br /> floodplain areas. <br /> D. Fill shall be properly compacted and the slopes shall <br /> be properly protected by the use of riprap, vegetative <br /> cover or other acceptable methods. The Federal Emergency <br /> Management Agency (FEMA) has established criteria for <br /> removing the special flood hazard area designation for <br /> certain structures properly elevated on fill above the <br /> 100-year flood elevation - FEMA' s requirements incorporate <br /> specific fill compaction and side slope protection <br /> standards for multi-structure or multi-lot developments. <br /> These standards should be investigated prior to the <br /> • initiation of site preparation if a change of special flood <br /> hazard area designation will be requested. <br /> 9.166 <br />
