All new construction and substantial improvements of residential structures, including basement and cellars, located within the Intermediate Regional Flood Plain must be elevated to one (1) foot above the maximum height of the 100-year flood. All new construction and substantial improvements of nonresidential structures including basements and cellars located within the Intermediate Regional Flood Plain shall be elevated or floodproofed watertight to one (1) foot above the maximum heights of the 100-year flood. Where such height is to be achieved by the use of fill, such fill shall be approved by the Chief Engineer and shall extend fifteen (15) feet beyond the limits of the intended structure. Such structures shall be designed and/or anchored to prevent the flotation, collapse, or lateral movement of the structure during the 100-year flood. When such floodproofing techniques are used the builder shall submit certification from a registered professional engineer or architect that the floodproofing methods are sufficient to preclude any damage to the structure arising from flood depths, pressures, velocities, the impact of uplift forces and other factors associated with the 100-year flood.
