Local Intense Precipitation 272.8 ft USLS35 Minimal 272.8 ft USLS35 FHRR Table 4-1 and FHRR Appendix A Streams and Rivers 272.8 ft USLS35 Not applicable 272.8 ft USLS35 FHRR Table 4-4 Unnamed Stream Storm Surge 252.8 ft USLS35 15.2 ft 268.0 ft USLS35 FHRR Sect 3.4.3 & Table 4-1 FHRR Table 4-1 PMSS + PMP + Waves 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.
