occupancy of the structure for times of flooding and only after determining that adequate flood warning time and local flood emergency response procedures exist. (b) Commercial Uses-accessory land uses, such as yards,railroad tracks, and parking lots may be at elevations lower than the regulatory flood protection elevation. However, a permit for such facilities to be used by the employees or the general public shall not be granted in the absence of a flood warning system that provides adequate time for evacuation if the area would be inundated to a depth and velocity such that when multiplying the depth(in feet)times velocity(in feet per second)the product number exceeds four(4)upon occurrence of the regional flood. (c) Manufacturing and Industrial Uses-measures shall be taken to minimize interference with normal plant operations especially along streams having protracted flood durations. Certain accessory land uses such as yards and parking lots may be at lower elevations subject to requirements set out in Section 78-1122(b)above. In considering permit applications, due consideration shall be given to needs of an industry whose business requires that it be located in flood plain areas. (d) Fill shall be properly compacted and the slopes shall be properly protected by the use of riprap,vegetative cover or other acceptable method. The Federal Emergency Management Agency(FEMA)has established criteria for removing the special flood hazard area designation for certain structures properly elevated on fill above the 100-year flood elevation-FEMA's requirements incorporate specific fill compaction and side slope protection standards for multi- structure or multi-lot developments. These standards should be investigated prior to the initiation of site preparation if a change of special flood hazard area designation will be requested. (e) Flood plain developments shall not adversely affect the hydraulic capacity of the channel and adjoining flood plain of any tributary watercourse or drainage system where a floodway or other encroachment limit has not been specified on the Official Floodplain Overlay District Map. (fl Standards for recreational vehicles are contained in Section 78-1131. (g) All manufactured homes must be securely anchored to an adequately anchored foundation system that resists flotation, collapse and lateral movement. Methods of anchoring may include,but are not to be limited to,use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable state or local anchoring requirements for resisting wind forces. DNISION 6.
