(A) The design flood shall be established by
			 the chief in concert with the applicant's desired level of protection, but with
			 the utmost interest in safeguarding life, health, and property. For class I
			 levees, the minimum design flood will be the one-hundred-year flood or the
			 critical flood. The design for the critical flood shall be for site-specific
			 conditions and based on a quantitative and relative impact analysis of the
			 protected area. In determining the critical flood, the levee shall be designed
			 so that there will be no additional potential for loss of life, health or
			 property from overtopping failure of the levee when compared to the potential
			 for loss of life, health or property caused by the flood in the absence of a
			 levee overtopping failure.
(B) The
			 magnitude of the design flood shall be determined from actual streamflow and
			 flood frequency records or from synthetic hydrologic criteria based on current
			 publications prepared by the division, the national oceanic and atmospheric
			 administration (NOAA), the United States army corps of engineers, the United
			 States geological survey, or others specifically approved by the chief.
