§ 155.45 STANDARDS FOR AREAS OF SHALLOW FLOODING (ZONE AO).

   (A)   Located within the Special Flood Hazard Areas established in § 155.07, are areas designated as shallow flooding areas.

   (B)   These areas have special flood hazards associated with base flood depths of 1 to 3 feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and indeterminate.

   (C)   In addition to § 155.40, all new construction and substantial improvements of all structures shall have the reference level elevated to:

      (1)   At least as high as the depth number specified on the Flood Insurance Rate Map (FIRM), in feet, plus a freeboard of 2 feet, above the highest adjacent grade; or

      (2)   At least 2 feet above the highest adjacent grade plus a freeboard of 2 feet if no depth number is specified.

   (D)   All new construction and substantial improvements of all non-residential structures may, in lieu of elevation, floodproof to the same depths as listed above so that any space below that level shall be water-tight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy.

   (E)   Certification is required as per §§ 155.26(C) and 155.41(B).
