FitzPatrick Table 2. Reevaluated Flood Hazards for Flood-Causing Mechanisms for Use in the MSA Mechanism Stillwater Waves/ Reevaluated Reference Elevation Runup Hazard Elevation Local Intense Precipitation 272.8 ft Minimal 272.8 ft FHRR Table 4-1 and FHRR USLS35 USLS35 Appendix A Streams and Rivers Unnamed Stream 272.8 ft Not 272.8 ft FHRR Table 4-4 USLS35 applicable USLS35 Storm Surge PMSS + PMP + Waves 252.8 ft 15.2 ft 268.0 ft FHRR Sect 3.4.3 & Table 4-1 USLS35 USLS35 FHRR Table 4-1 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 2: Reevaluated hazard mechanisms bounded by the current design basis (see Table 1) are not included in this table.

Note 3: Reported values are rounded to the nearest one-tenth of a foot.
