Future-Conditions Hydrology Final Rule

The Final Rule for Future-Conditions Hydrology revises Parts 59 and 64 of the National Flood Insurance Program (NFIP) regulations to include definitions for future-conditions hydrology and for the floodplains that may be shown on Flood Insurance Rate Maps (FIRMs), for informational purposes at the request of a community, to reflect future-conditions hydrology; and to establish the zone symbol to be used to identify future-conditions flood hazard areas on the FIRMs. A complete summary of our evaluation of future-conditions hydrology is documented in the final version of a report entitled "Modernizing FEMA's Flood Hazard Mapping Program: Recommendations for Using Future-Conditions Hydrology for the National Flood Insurance Program.
