HomeMy WebLinkAbout83-2048 - Flood Insurance Rate MapNOTES 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.
To obtain more detailed information in areas where Base Flood Elevations (BFEs)
and/or floodways have been determined, users are encouraged to consult the Flood
Profiles and Floodway Data and/or Summary of Stillwater Elevations 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. 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 Report should be utilized in conjunction with
the FIRM for purposes of construction and/or floodplain management.
Coastal Base Flood Elevations shown on this map apply only landward of 0.0
North American Vertical Datum of 1988 (NAVD 88). 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 jurisdiction. 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.
The AE Zone category has been divided by a Limit of Moderate Wave Action
(LiMWA). The LiMWA represents the approximate landward limit of the 1.5 -foot
breaking wave. The effects of wave hazards between the VE Zone and the LIMWA
(or between the shoreline and the LiMWAfor areas where VE Zones are not identified)
will be similar to, but less severe than those in the VE Zone.
Certain areas not in Special Flood Hazard Areas may be protected by flood control
structures. Refer to Section 2.4 "Flood Protection Measures" of the Flood Insurance
Study Report for information on flood control structures for this jurisdiction.
The projection used in the preparation of this map was Massachusetts State Plane
Mainland Zone (FIPS zone 2001). The horizontal datum was NAD 83, GRS 1980
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 this FIRM.
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

Base map information shown on this FIRM was derived from digital
orthophotography. Basemap files were provided in digital form by
Massachusetts Geographic Information System (MassG1S). Ortho imagery was
produced at a scale of 1:5000 and is dated April 2009. The projection used in
the preparation of this map is Massachusetts State Plane Mainland
(FIPSZONE2001). The horizontal datum is NAD 83, GRS1980 spheroid.
Corporate limits shown on this map are based on the best data available at the time
of publication. Because changes due to annexations or de -annexations may have
occurred after this map was published, map users should contact appropria`.e
community officials to verify current corporate limit locations.

SPECIAL FLOOD HAZARD AREAS (SFHAs) SUBJECT TO
INUNDATION BY THE 1% ANNUAL CHANCE FLOOD
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, A0, AR, A99, V, and VE. The Base Flood Elevation is the water -surface
elevation of the 1% annual chance flood.
ZONE A No Base Flood Elevations determined.
ZONE AE Base Flood Elevations detennined.
ZONE AH Flood depths of 1 to 3 feet (usually areas of ponding); Base Flood Elevations
determined.
ZONE AO 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.
ZONE AR Special Flood Hazard Areas formerly protected from the 1% annual chance
flood 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.
ZONE A99 Area to be protected from 1% annual chance flood by a Federal flood
protection system under construction; no Base Flood Elevations determined.
ZONE V Coastal flood zone with velocity hazard (wave action); no Base Flood Elevations
determined.
ZONE VE Coastal flood zone with velocity hazard (wave action); Base Flood Elevations
determined.
FLOODWAY AREAS IN ZONE AE
The floodway Is the channel of a stream 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
ZONE X 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
ZONE X Areas determined to be outside the 0.2% annual chance floodplain.
ZONE D Areas In which flood hazards are undetermined, but possible.
