91.1612.5.  Flood Hazard Documentation.  The following documentation shall be prepared and sealed by a registered design professional and submitted to the Department:
 
   1.    For construction in flood hazard areas not subject to high-velocity wave action:
 
   1.1.    The elevation of the lowest floor, including the basement member.
 
   1.2.   For fully enclosed areas below the design flood elevation where provisions to allow for the automatic entry and exit of floodwaters do not meet the minimum requirements in Section 2.7.2.1 of American Society of Civil Engineers (ASCE) 24, construction documents shall include a statement that the design will provide for equalization of hydrostatic flood forces in accordance with Section 2.7.2.2 of ASCE 24.  (Amended by Ord. No. 184,692, Eff. 12/30/16.)
 
   1.3.    For dry floodproofed nonresidential buildings, construction documents shall include a statement that the dry floodproofing is designed in accordance with ASCE 24.
 
   2.    For construction in flood hazard areas subject to high-velocity wave action:
 
   2.1.    The elevation of the bottom of the lowest horizontal structural.
 
   2.2.    Construction documents shall include a statement that the building is designed in accordance with American Society of Civil Engineers (ASCE) 24, including that the pile or column foundation and building or structure to be attached is designed to be anchored to resist flotation, collapse and lateral movement due to the effects of wind and flood loads acting simultaneously on all building components, and other load requirements of CBC Chapter 16. (Amended by Ord. No. 185,587, Eff. 7/16/18.)
 
   2.3.   For breakaway walls designed to resist a nominal load of less than 10 psf (0.48 kN/m2) or more than 20 psf (0.96 kN/m2), construction documents shall include a statement that the breakaway wall is designed in accordance with ASCE 24.
