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 Acting Deputy 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 <a href="https://msc.fema.gov">https://msc.fema.gov</a>.
