<br />Section D. <br /> <br />STANDARDS FOR AREAS OF SHALLOW FLOODING (AO ZONES)' <br /> <br />Located within the areas of Special Flood Hazard established in Article 3, Section B, are <br />areas designated as shallow flooding areas. These areas have flood hazards associated with <br />base flood depths of one to three (1 '-3') feet, where a clearly defined channel does not exist <br />and where the path of flooding is unpredictable and indeterminate; therefore, the following <br />provisions apply: <br /> <br />(1) All new construction and substantial improvements of residential <br />structures shall have the lowest floor, including basement, elevated to the <br />flood depth number specified on the Flood Insurance Rate Map, above the <br />highest adjacent grade. If no flood depth number is specified, the lowest <br />flood, including basement, shall be elevated at least two (2) feet above the <br />highest adjacent grade. <br /> <br />(2) All new construction and substantial improvements ofnon-residential <br />structures shall: <br /> <br />( a) Have the lowest floor, including basement, elevated to <br />the flood depth number specified on the Flood Insurance Rate <br />Map above the highest adjacent grade. If no flood depth <br />number is specified, the lowest floor, including basement, <br />shall be elevated at least two feet (2') above the highest <br />adjacent grade; or <br /> <br />(b) Together with attendant utility and sanitary facilities <br />be completely flood-proofed to the specified flood level so <br />that any space below that level is watertight with walls <br />substantially impermeable to the passage of water and with <br />structural components having the capability of resisting <br />hydrostatic and hydrodynamic loads and effects of buoyancy . <br />Certification is required as state in Article 5, Section B(2). <br /> <br />Section E. <br /> <br />STANDARDS FOR SUBDIVISION PROPOSALS. <br /> <br />(1) All subdivision proposals shall be consistent with the need to <br />minimize flood damage. <br /> <br />(2) All subdivision proposals shall have public utilities and facilities such <br />as sewer, gas, electrical and water systems located and constructed to <br />minimize flood damage. <br /> <br />(3) All subdivision proposals shall have adequate drainage provided to <br />reduce exposure to flood hazards. <br /> <br />Flood Damage Prevention <br /> <br />-18- <br />
