To obtain more detailed information in areas where Base Flood
Elevations (BFEs) and/or f100dways have been determined, users are
encouraged to consult the Flood Profiles and Floodway Data tables
contained within the Flood Insurance Study (FIS) report that
accompanies this FIRM. Users should be aware that BFEs shown on the
FIRM represent rounded whole-foot elevations and therefore may not
exactly reflect the flood elevation data presented in the FIS. For
construction and/or floodplain management purposes, users are
encouraged to use the flood elevation data presented in this FIS in
conjunction with the data shown on the FIRM.

Elevation Reference Marks (ERM) elevations listed on this map were
obtained andlor developed to establish vertical control for determination
of flood elevations and floodplain boundaries portrayed on this map.
Users should be aware thai these ERM elevations may have changed
since the publication of this map. To obtain up-to-date-elevation
information on National Geodetic Survey (NGS) ERMs shown on this
map, please contact the Information Services Branch of the NGS at (301)
713-3242, or visit their website at www.ngs.noaa.gov. Map users should
seek verification of non-NGS ERM monument elevations when using
these elevations for construction or floodplain management purposes.

ZONE

Coastal 8FE's shown on this map apply only landward of 0.0' National
Geodetic Vertical Datum (NGVD). Users of this FIRM should be aware
that coastal flood elevations are also 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.

Base flood elevations determined.

ZONE AE
ZONE AH

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

on sloping terrain); average depths deter-
mined. For areas of alluvial fan flooding;
velocities also determined,

ZON E AO

Federal flood protection system under con-
struction; no base flood elevations deter-
mined.

action); no base flood elevations determined.

ZONE VE Coastal flood with velocity hazard (wave
action); base flood elevations determined.

flood with average depths of less than 1 foot or

NOTES

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, or all planimetric features outside
Special Flood Hazard Areas. The community map repository should be
consulted for more detailed data on BFEs, and for any information on
floodway delineations, prior to use of this map for property purchase or
construction purposes.

Areas of Special Flood Hazard (1 OO-year flood) include Zones A, AE, A 1-
A30, AH, AO, A99, V, VE and V1-V30.

Certain areas not in Special Flood Hazard Areas may be protected by flood
control structures.

Boundaries of the f100dways were computed at cross sections and
interpolated between cross sections. The floodways were based on
hydraulic considerations with regard to requirements of the Federal
Emergency Management Agency.

Floodwaywidths in some areas may be too narrow to show to scale. Refer
to Floodway Data Table where floodway width is shown at 1/20 inch.

Corrorate limits shown are current as of the date of this map. The user
should contact appropriate community officials to determine if corporate
limits have changed subsequent to the issuance of this map.

For adjoining panels, see separately printed Map Index.
