Changes in Flood Hazard Determinations
AGENCY:
Federal Emergency Management Agency, Department of Homeland Security.
ACTION:
Notice.
SUMMARY:
New or modified Base (1-percent annual chance) Flood Elevations (BFEs), base flood depths, Special Flood Hazard Area (SFHA) boundaries or zone designations, and/or regulatory floodways (hereinafter referred to as flood hazard determinations) as shown on the indicated Letter of Map Revision (LOMR) for each of the communities listed in the table below are finalized. Each LOMR revises the Flood Insurance Rate Maps (FIRMs), and in some cases the Flood Insurance Study (FIS) reports, currently in effect for the listed communities.
DATES:
Each LOMR was finalized as in the table below.
ADDRESSES:
Each LOMR is available for inspection at both the respective Community Map Repository address listed in the table below and online through the FEMA Map Service Center at
https://msc.fema.gov.
FOR FURTHER INFORMATION CONTACT:
David N. Bascom, Acting Director, Engineering and Modeling Division, Federal Insurance Directorate, Resilience, FEMA, 400 C Street SW, Washington, DC 20472, or (email)
david.bascom@fema.dhs.gov;
or visit the FEMA Mapping and Insurance eXchange (FMIX) online at
https://www.floodmaps.fema.gov/fhm/fmx_main.html.
SUPPLEMENTARY INFORMATION:
The Federal Emergency Management Agency (FEMA) makes the final flood hazard determinations as shown in the LOMRs for each community listed in the table below. Notice of these modified flood hazard determinations has been published in newspapers of local circulation and 90 days have elapsed since that publication. The Assistant Administrator, Federal Insurance Directorate, Resilience has resolved any appeals resulting from this notification.
The modified flood hazard determinations are made pursuant to section 206 of the Flood Disaster Protection Act of 1973, 42 U.S.C. 4105, and are in accordance with the National Flood Insurance Act of 1968, 42 U.S.C. 4001
et seq.,
and with 44 CFR part 65.
The current effective community number is shown and must be used for all new policies and renewals.
The new or modified flood hazard information is the basis for the floodplain management measures that the community is required either to adopt or to show evidence of being already in effect in order to remain qualified for participation in the National Flood Insurance Program (NFIP).
This new or modified flood hazard information, together with the floodplain management criteria required by 44 CFR 60.3, are the minimum that are required. They should not be construed to mean that the community must change any existing ordinances that are more stringent in their floodplain management requirements. The community may at any time enact stricter requirements of its own or pursuant to policies established by other Federal, State, or regional entities.
This new or modified flood hazard determinations are used to meet the floodplain management requirements of the NFIP. The changes in flood hazard determinations are in accordance with 44 CFR 65.4.
Interested lessees and owners of real property are encouraged to review the final flood hazard information available at the address cited below for each community or online through the FEMA Map Service Center at
https://msc.fema.gov.
