<br /> ø4A~\1 <br /> permanent foundation such that the lowest floor of the manufactured home is elevated <br /> to or above the base flood elevation and be securely fastened to an adequately <br /> anchored foundation system to resist flotation, collapse, and lateral movement. <br /> Upon the completion of the structure, the elevation of the lowest floor including <br /> basement shall be certified by a registered professional engineer or surveyor, and <br /> verified by the City's building inspector to be properly elevated. Such certification and <br /> verification shall be provided to the Floodplain Administrator. <br /> Sec. 41.5.5. FLOODWAYS: Located within areas of special flood hazard <br /> established in Section 41.3.2, are areas designated as floodways. Since the floodway <br /> is an extremely hazardous area due to the velocity of flood waters, which carry debris, <br /> potential projectiles, and erosion potential, the following provisions apply: <br /> A. Prohibit encroachments, including fill, new construction, substantial <br /> improvement, and other new development unless certification by a <br /> registered professional engineer is provided demonstrating that <br /> encroachments shall not result in any increase in the base flood elevation <br /> during the occurrence of the base flood discharge. <br /> B. If section 41.5.5.A., above, is satisfied, all new construction, substantial <br /> improvement, and other proposed new development shall comply with all <br /> other applicable flood hazard reduction provisions of Article III. <br /> Sec. 41.5.6 COASTAL HIGH HAZARD AREAS: Within coastal high <br /> hazard areas as established under Section 41.3.2, the following standards shall apply: <br /> A. All new construction and substantial improvement shall be elevated on <br /> adequately anchored pilings or columns and securely anchored to such <br /> pilings or columns so that the lowest horizontal portion of the structural <br /> members of the lowest floor (excluding the pilings or columns) is elevated <br /> to or above the base flood level. The pile or column foundation and <br /> structure attached thereto is anchored to resist flotation, collapse, and <br /> lateral movement due to the effects of wind and water loads acting <br /> simultaneously on all building components. Water loading values used <br /> shall be those associated with the base flood. Wind loading values used <br /> shall be those required by applicable state or local building standards. <br /> B. All new construction and other development shall be located on the <br /> landward side of the reach of mean high tide. <br /> C. All new construction and substantial improvement shall have the space <br /> below the lowest floor free of obstructions or constructed with breakaway <br /> walls as defined in Article II of this ordinance. Such enclosed space shall <br /> not be used for human habitation and will be usable solely for parking of <br /> vehicles, building access or storage. <br /> D. Fill shall not be used for structural support of buildings. <br /> E. Man-made alteration of sand dunes which would increase potential flood <br /> damage is prohibited. <br /> F. The Floodplain Administrator shall obtain and maintain the following <br /> records: <br /> Atty/Ord/Ord.223 <br /> 102704 15 <br /> -- -T- <br />
