<br />-9- <br /> <br />Sec. 5-60. <br /> <br />General Standards For Construction. <br /> <br />In all areas of special flood hazards the following provisions <br />are required for all new construction and substantial <br />improvements; <br /> <br />a. All new construction or substantial improvements shall be <br />designed (or modified) and adequately anchored to prevent <br />flotation, collapse or lateral movement of the structure <br />resulting from hydrodynamic and hydrostatic loads, including the <br />effects of buoyancy; <br /> <br />b. All new construction or substantial imrpovements shall be <br />constructed by methods and practices that minimize flood damage; <br /> <br />c. All new construction or substantial improvements shall <br />constructed with materials resistant to flood damage; <br /> <br />be <br /> <br />d. All new construction or substantial improvements shall be <br />constructed with electrical, heating, ventalation, plumbing, and <br />air conditioning equipment and other service facilities that are <br />designed and/or located so as to prevent water from entering <br />or accumulating within the components during conditions of <br />flooding. <br /> <br />e. All new and replacement water supply systems shall be <br />designed to minimize or eliminate infiltration of flood waters <br />into the system. <br /> <br />f. Newand replacement sanitary sewage systems shall be <br />designed to minimize or eliminate infiltration of flood waters <br />into the system and discharge from the systems into flood <br />waters; and, <br /> <br />g. On-site waste disposal systems shall be located to avoid <br />impairment to them or contamination from them during flooding. <br /> <br />Sec. 5-61. <br /> <br />Specific Standards For Construction. <br /> <br />In all areas of special <br />provisions are required: <br /> <br />flood <br /> <br />hazards the following <br /> <br />a. Residential Construction- new construction and substantial <br />improvement of any residential structure shall have the lowest <br />floor (including basement), elevated to or above the base flood <br />elevation. A registered professional engineer, architect, or <br />land surveyor shall submit a certification to the Flood Plain <br />Administrator that this standard is satisfied. <br /> <br />b. Non-residential Construction- new construction and <br />substantial improvements of any commercial, industrial or other <br />non-residential structure shall either have the lowest floor <br />(including basement) elevated to or above the base flood level <br />or, together with attendent utility and sanitary facilities, be <br />designed so that below the base flood level the structure is <br />watertight with walls substantially impermeable to the passage <br />of water and with structural components having the capability of <br />rccic~:~; hyjrostatic and hydrodynamic loads and effects of <br />buoyancy. A registered professional engineer or architect shall <br />develop and/or review structural design, specifications, and <br />plans for the construction, and shall certify that the design <br />and methods of construction are in accordance with accepted <br />standards of practice as outlined in this subsection. A record <br />of such certification which includes the specific elevation in <br />relation to mean sea level to which such structures are <br />floodproofed, shall be maintained by the Flood Plain <br />Administrator. <br />
