This map is for use in administering the National Flood Insurance Program. It
does not necessarily identify all areas subject to flooding, particularly from local
drainage sources of small size. The community map repository should be
consulted for possible updated or additional flood hazard information.

To obtain more detailed information in areas where Base Flood Elevation
{BFEs) andlor floodways have been determined, users are encouraged to consult
the Flood Profiles and Floodway Data tables contained within the Flood Insur-
ance Study (FlS) report that accompanies this ARM. Users should be aware that
BFEsshown on the FIRM represent rounded whole-foot elevations. These BFEs
are intended for flood insurance rating purposes only and should not be used
as the sole source of flood elevation information. Accordingly, flood elevation
data presented in the AS should be utilized in conjunction with the FIRM for
purposes of construction andlor floodplain management.

Coastal Sase Flood Elevation fBFEs) shown on this map apply only land-
ward of 0.0' North American Vertical Datum (NAVD). Users of this ARM
should be aware that coastal flood elevations may also be provided in the
Summary of Stillwater Elevations table in the Flood Insurance Study report for
this community. Elevations shown in the Summary of Stillwater Elevations table
should be used for construction, andlor floodplain management purposes when
they are higher than the elevations shown on this fiRM.

Boundaries of the fJoodweys were computed at cross sections and interpolated
between cross sections. The floodways were based on hydraulic considerations
with regard to requirements of the National Flood Insurance Program. Floodwav
widths and other pertinent floodway data are provided in the Flood Insurance
Study report for this jurisdiction.

Certain aTeas not in Special Rood Ha2ard Areas may be protected by flood
control stnu:tuYeS. Refer to Section 2.4 "Flood Protection MeasuresH of
the Flood Insurance Study report for information on flood control structures
in this jurisdiction.

The [pJ':Oj&ction used in the preparation of this map is Universal Tranverse
Mercator (UTM) zone 13. The horizontal datum is NADe3, GRS 1980
spheroid. Differences in datum, spheroid, projection or UTM zones used in
the production of ARMs for adjacent jurisdictions may result in slight positional
differences in map features across jurisdiction boundaries. These differences
do not affect the accuracy of the FIRM.

Flood elevations on this map are referenced to the North American Vertical
Datum of 1988. These flood elevations must be compared to structure and
ground elevations referenced to the same vertical datum. For information
regarding conversion between the National Geodetic Vertical Datum of 1929
and the North American Vertical Datum of 1988, visit the National Geodetic
Survey website at www.ngs.noaa.gov or contact the National Geodetic Survey

at the tirm~ of publication. Because changes due to annexations or de-annexations
may have occurred after this map was published, map users should contact
appropriate community officials to verify current corporate limit locations.

This map reflects more detailed and up-to-date stream channel configurations
than those shown on the previous FIRM for this jurisdiction. The floodplains
and floodways that were transferred from the previous FIRM may have been
adjusted to conform to these new stream channel configurations. As a
result, the Flood Profiles and Floodway Data tables in the Flood Insurance
Study report may reflect stream channel distances that differ from what is
shown on this map.

SPECIAL FLOOD HAZARD AREAS SUBJECT TO JNUNDA TION

JOINS PANEL 0890

The 1 % annual ohance flood (1 OO-year flood), also known as the base flood, is the flood
that has a 1 % ohanoe of being equaled or exceeded in any given year. The Speoial
Flood Hazard Area is the area subject to flooding by the 1 % annual ohance flood. Areas
of Special Flood Hazard inolude Zones A, AE, AH, AO, AR, A99, V, and VE. The Base
Flood Elevation is the water surface elevation of the 1 % annual chanoe flood.
