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 01 small size. The community map repository should be
consulted for possible updated or additional flood hazard information.

JOINS PANEL 0895

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 iFlS) 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 FlRM 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 ARM.

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.

Certain areas not in Special Flood Hazard Areas may be protected by flood
eontroJ structures. Refer to Section 2.4 "flood Protection Measures" 01
the Flood Insurance Study report for information on flood control structures
in this jurisdiction.

ZONE X

The projection used in the preparation 01 this map is Universal Tranverse
Mercator (UTM) zone 13. The horizontal 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.

This map reflects more detailed and up-to-date stream channel configurations
than those shown on the previous FIRM tor this jurisdiction. The floodplains
and floodways that were transferred from the previous FlRM may have been
adjusted ta conform to these new stream channel configurations. As a
result, the Flood Profiles and Roodway 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 INUNDATION
BY THE 1 % ANNUAL CHANCE FLOOD EVENT

The 1 % annual chance flood t1 OO-year flood), also known as the base flood, is the flood
that has a 1 % chanoe of being equaled or exceeded in any given year. The Special
Aood Hazard Area is the area subjeot to flooding by the 1% annual chance flood. Areas
of Special Flood Hazard include Zones A, AE, AH, AO, AR, ASS, V, and VE. The Base
Aood Elevation is the water surface elevation of the 1 % annual chance flood.

ZONE A

ZONE VI:

No base flood elevations determined.

Base flood elevations determined.

Rood 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 flood control system is
baing restored to provide protection from the 1 % annual chance or
greater flood event.

Area to be protected from 1 % annual chance flood event by a Federal
flood protection 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 floodway is the channel of a str.eam plus any adjacent floodplain areas that must be
kept free of encroachment so that the 1 % annual chance flood can be carried without
substantial increases in flood heights.

OTHER FLOOD AREAS

Areas of 0.2% annual chance flood; areas of 1 % annual chance flood
with average depths of less than 1 foot or with drainage areas less than
1 square mile; and areas protected by levees from 1 % annual chance
flood.

OTHER AREAS

Areas determined to be outside the 0.2% annual chance floodplain.
Areas in which flood hazards are undetermined, but possible.
