Note 1: The licensee is expected to develop flood event duration parameters and applicable flood associated effects to conduct the MSA. The staff will evaluate the flood event duration parameters (including warning time and period of inundation) and flood associated effects during its review of the MSA.

Note 4: "The Perry Local datum is originally based on and within the tolerance levels of the NGVD 29 datum."
