In all flood zones, underground tanks shall be anchored to prevent flotation, collapse and lateral movement under conditions of the base flood. In VE and Coastal AE zones, above-ground storage tanks which are located outside or inside of a structure must be elevated one foot above the base flood elevation (BFE). Where elevated on platforms, the platforms shall be cantilevered from or knee braced to the building or shall be supported on elevated foundations that conform to the standards for the particular flood zone as described in § 5.3. In A and AE zones, above-ground storage tanks which are located outside or inside of a structure shall be elevated one foot above the base flood elevation (BFE) or shall be securely anchored to prevent flotation, collapse or lateral movement under conditions of the base flood. Anchored tanks must have the top of the fill pipe located at least one foot above the BFE and have a screw fill cap that does not allow for the infiltration of flood water.
