LEGENDSPECIAL FLOOD HAZARD AREAS (SFHAs) SUBJECT TOINUNDATION BY THE 1% ANNUAL CHANCE FLOOD
The 1% annual chance flood (100-year flood), also known as the base flood, is the floodthat has a 1% chance of being equaled or exceeded in any given year. The SpecialFlood Hazard Area is the area subject to flooding by the 1% annual chance flood. Areasof Special Flood Hazard include Zones A, AE, AH, AO, AR, A99, V and VE. The BaseFlood Elevation is the water-surface elevation of the 1% annual chance flood.
ZONE A No Base Flood Elevations determined.
ZONE AE Base Flood Elevations determined.
ZONE AH Flood depths of 1 to 3 feet (usually areas of ponding); Base FloodElevations 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, velocitiesalso determined.
ZONE AR Special Flood Hazard Area formerly protected from the 1% annualchance flood by a flood control system that was subsequentlydecertified. Zone AR indicates that the former flood control system isbeing restored to provide protection from the 1% annual chance orgreater flood.
ZONE A99 Area to be protected from 1% annual chance flood by a Federalflood protection system under construction; no Base Flood Elevationsdetermined.
ZONE V Coastal flood zone with velocity hazard (wave action); no Base FloodElevations determined.
ZONE VE Coastal flood zone with velocity hazard (wave action); Base FloodElevations determined.
FLOODWAY AREAS IN ZONE AE
The floodway is the channel of a stream plus any adjacent floodplain areas that must bekept free of encroachment so that the 1% annual chance flood can be carried withoutsubstantial increases in flood heights.
OTHER FLOOD AREAS
ZONE X Areas of 0.2% annual chance flood; areas of 1% annual chance floodwith average depths of less than 1 foot or with drainage areas less than1 square mile; and areas protected by levees from 1% annual chanceflood.
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.
COASTAL BARRIER RESOURCES SYSTEM (CBRS) AREAS
OTHERWISE PROTECTED AREAS (OPAs)
CBRS areas and OPAs are normally located within or adjacent to Special Flood Hazard Areas.

NOTES TO USERSThis map is for use in administering the National Flood Insurance Program. Itdoes not necessarily identify all areas subject to flooding, particularly from local
community map repositorydrainage sources of small size. The should beconsulted for possible updated or additional flood hazard information.
Base Flood ElevationsTo obtain more detailed information in areas where floodways(BFEs) and/or have been determined, users are encouraged to consult
the Flood Profiles and Floodway Data and/or Summary of Stillwater Elevationstables contained within the Flood Insurance Study (FIS) report that accompaniesthis FIRM. Users should be aware that BFEs shown on the FIRM representrounded whole- foot elevations. These BFEs are intended for flood insurancerating purposes only and should not be used as the sole source of floodelevation information. Accordingly, flood elevation data presented in the FISreport should be utilized in conjunction with the FIRM for purposes ofconstruction and/or floodplain management.
Coastal Base Flood Elevations shown on this map apply only landwardNorth American Vertical Datum of 1988 (NAVD 88).of 0.0' Users of this
FIRM should be aware that coastal flood elevations are also provided in theSummary of Stillwater Elevations table in the Flood Insurance Study reportfor this jurisdiction. Elevations shown in the Summary of Stillwater Elevationstable should be used for construction and/or floodplain management purposeswhen they are higher than the elevations shown on this FIRM.
floodwaysBoundaries of the were computed at cross sections and interpolatedbetween cross sections. The floodways were based on hydraulic considerationswith regard to requirements of the National Flood Insurance Program. Floodwaywidths and other pertinent floodway data are provided in the Flood InsuranceStudy report for this jurisdiction.
Certain areas not in Special Flood Hazard Areas may be protected by floodcontrol structures. Refer to Section 2.4 "Flood Protection Measures" ofthe Flood Insurance Study report for information on flood control structuresfor this jurisdiction.

Base map information shown on this FIRM was derived from U.S. Geological SurveyDigital Orthophoto Quadrangles produced at a scale of 1:12,000 from photographydated 1998 or later. These images were recast by NH GRANIT onto the NH StatePlane coordinate system.
This map reflects more detailed and up- to- date stream channel configurationsthan those shown on the previous FIRM for this jurisdiction. The floodplainsand floodways that were transferred from the previous FIRM may have beenadjusted to conform to these new stream channel configurations. As aresult, the Flood Profiles and Floodway Data tables in the Flood InsuranceStudy report (which contains authoritative hydraulic data) may reflect streamchannel distances that differ from what is shown on this map.
Corporate limits shown on this map are based on the best data availableat the time of publication. Because changes due to annexations or de- annexationsmay have occurred after this map was published, map users should contactappropriate community officials to verify current corporate limit locations.
