Construction of new critical <br /> facilities may be permissible within the floodplain if it is specifically <br /> documented that no feasible alternative site is available. Critical facilities <br /> constructed within the SFHA shall have the lowest floor (including basement) <br /> elevated or structurally dry floodproofed to the 500-year flood frequency <br /> elevation or three (3) feet above the level of the 100-year flood frequency <br /> elevation whichever is greater. Floodproofing and sealing measures must be <br /> taken to ensure that toxic substances will not be displaced by or released into <br /> floodwaters. Access routes elevated to or above the level of the base flood <br /> elevation shall be provided to all critical facilities; and, <br /> f.
