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

107000 '00"
40030'00"

The 10/0 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.

To obtain more detailed information in areas where Base Flood Elevation
(BFEs) Bnd/or floodways have been determined, users are encouraged to consult
the Flood Profiles and Floodway Data tables contained within the Flood Insur-
ance Study (AS) 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.

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.

Boundaries 01 the f)~odways were computed at cross sections and interpolated
between cross sections. The floodways were based on hydraulic considerations
with regard to requirements of the National Rood Insurance Program. Floodway
widths and other pertinent floodway data are provided in the Flood Insurance
Study report for this jurisdiction.

Base flood elevations determined.

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

Rood 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 fl'Ood control system is
being restored to pr'Ovide protecti'On from the 1 % annual chance or
greater flood avent.

Area to be protected from 1 % annual chance flood avent by a Federal
flo'Od pr'Otection system under construction; no base flood elevations
determined.

Coastal flood zone with velocity hazard (wave action); no base flood
elevations determined.

Coastal flood zone with velOCity hazard (wave action); base flood elevations
determined.

FLOODWAY AREAS IN ZONE AE

The f100dway is the channel of a stream plus any adjacent floodplain areas that must be
kept frae of encroachment so that the 1 % annual chance fl'Ood can be carried without
substantial increases in flood heights.

The projedion used in the preparation of this map is Universal Tranverse
Mercator (UTM) zone 13. The hori2orrtaJ datum is NAD83, GRS1980
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.

ZONE X

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

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.
