tory floodplain for your office and the public to use. All map corrections and
notices of map revisions should be recorded and denoted on administrative maps,
with the details kept in an indexed file.
You should also cooperate with federal, state and local agencies, and private
firms, undertaking flood studies. You must submit any new floodplain data to the
FEMA Regional Office within six months of their development. Community staff
should review revisions to maps (including Conditional Letters of Map Revision
and Letters of Map Revision) to ensure they meet yaur regulations.
You must notify the FEMA Regional Office and the state within one year of
an annexation or when your community has assumed or relinquished authority to
adopt or enforce floodplain management regulations for a particular area. The
NFIP has special procedures that need to be followed to ensure that these areas
are properly mapped and regulated and remain eligible for flood insurance.
44 CFR 59.22(a)(9)(v) Upon occurrence, [the community must) notify the Admin-
istrator in writing whenever the boundaries of the community have been modified
by annexation or the community has otherwise assumed or no longer has author-
ity to adopt and enforce flood plain management regulations for a particular area.
In order that all FHBMs and FIRMS accurately represent the community's
boundaries, include within such notification a copy of a map of the community
suitable for reproduction, clearly delineating the new corporate limits or new area
for which the community has assumed or relinquished flood plain management
re ulator authorit .
You must notify the FEMA Regional Office and the state within six months of
physical changes that can affect flooding conditions, such as channel modifica-
tions or upstream detention.
44 CFR 65.3. A community's base flood elevations may increase or decrease re-
sulting from physical changes affecting flooding conditions. As soon as
practicable, but not later than six months after the date such information be-
comes available, a community shall notify the Administrator of the changes by
submitting technical or scientific data in accordance with this part. Such a sub-
mission is necessary so that upon confirmation of those physical changes
affecting Flooding conditions, risk premium rates and flood plain management re-
quirements will be based upon current data.
Update the ordinance: If your community is notified of changes in federal or
state laws and/or regulations that would require changing your floodplain man-
agement ordinance, you must revise your ordinance within six months.
44 CFR 60.7. From time to time Part 60 may be revised as experience is ac-
quired under the Program and new information becomes available. Communities
will be given six months from the effective date of any new regulation to revise
their flood plain mana ement re ulations to comply with an such than es.
