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

JOINS PANEL 0881

The 1% annual chance flood (100-year flood), also known as the base flood, is the flood
that has a 1 % ohanoe of being equaled or exoeeded in any giyen year. The Speoial
Rood Hazard Area is the area subject to flooding by the 1 % annual ohance flood. Areas
of Speoial Flood Hazard inolude Zones A, At, AH, AO, AR, ASS, V, and VE. The Bass
Flood Elevation is the water surfaoe elevation of the 1 % annual chance flood.

ZONE AO

To obtain mare detailed information in areas where Base Flood Elevation
(BFEs) andlor floodways have been determined, users are encouraged to consult
the Flood Prafiles and Floodway Data tables contained within the Rood Insur-
ance Study (RS) report that accompanies this RRM. Users shauld be aware that
BFEs shawn on the FIRM represent rounded whale-foat elevations. These BFEs
are intended far flood insurance rating purposes only and should not be used
as the sole source of flood elevatian information. Accordingly, flood elevation
data presented in the FtS should be utilized in conjunction with the FIRM for
purposes of construction andlor 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, andlor floodplain management purpases when
they are higher than the elevations shown on this FlRM.

ZONE V

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

ZONE VE

Certain areas not in Special Flood Hazard Areas may be protected by flood
contJ':oJ strudlt.res. Refer to Section 2.4 "Flood Protection Measures" of
the Flood Insurance Study repart for information on flood c.ontrol structures
in this jurisdiction.

lONE X

Thepro)ection used in the preparation of this map is Universal Tranverse
Mercator (UTM) zane 13. The horizontal datum is NAD83, GRS1980
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.

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 yertical 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

No base flood elevations detmmined.

Base flood elevations determined.

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

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

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

Area to be protected from 1 % annual chance floodevant 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 (waveaotion); base flood elevations
determined.

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 proteoted 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.

OTHERWISE PROTECTED AREAS (OPAs)

ZONE X

................

The flood way is the channel of a stream plus any adlecMt floodplain areas that must be
kept free of encroaohment so that the 1 % annual chance flood oan be carried without
substantial increases in flood heights.

CBRS areas and OPAs are normally located within or adjacent to Spacial Flood Hazard Areas.

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 Roodway Data tables in the Flood Insurance
Study report may reflect stream channel distances that differ from what is
shown on this map.
