NOTES

TO

USERS

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.

SPECIAL FLOOD HAZARD AREAS SUBJECT TO INUNDATION
BY THE 1 % ANNUAL CHANCE FLOOD EVENT

LEGEND

1 05 003'45 /I
390S4'22.5/1

The 1 % annual chance flood (100-year flood), also known as the base flood, is the flood
that has a 1 % chance of being equaled or exceeded in any given year. The Special
Flood Hazard Area is the area subject to flooding by the 1 % annual chance flood. Areas
of Special Flood Hazard include Zones A, AE, AH, AO, AR, A99, V, and VE. The Base
Flood Elevation is the water surface elevation of the 1 % annual chance flood.

No base flood elevations determined.

To obtain more detailed information in areas where Base Flood Elevation
(BFEs) and/or floodways have been determined, users are encouraged to consult
the Flood Profiles and Floodway Data tables contained within the Flood Insur-
ance Study (FIS) report that accompanies this FIRM. Users should be aware that
BFEs shown 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 FIS should be utilized in conjunction with the FIRM for
purposes of construction and/or floodplain management.

Flood depths of 1 to 3 feet (usually areas of ponding); base flood
elevations determined.

Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain);
average depths determined. For areas of alluvial fan flooding, velocities
also determined.

Area of special flood hazard formerly protected from the 1 % annual
chance flood event by a flood control system that was subsequently
decertified. Zone AR indicates that the former flood control system is
being restored to provide protection from the 1 % annual chance or
greater flood event.

ZONE AR

Coastal Base Flood Elevation (BFEs) shown on this map apply only land-
ward of 0.0' National Geodetic Vertical Datum (NGVD). Users of this FIRM
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, and/or floodplain management purposes when
they are higher than the elevations shown on this FIRM.

flood protection system under construction; no base flood elevations
determined.

Boundaries of the floodways 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. Floodway
widths and other pertinent floodway data are provided in the Flood Insurance
Study report for this jurisdiction.

The projection used in the preparation of this map is Universal Tranverse

spheroid. Differences in datum, spheroid, projection or UTM zones used in
the production of FIRMs 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.
