The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the State Plane projection and coordinate system.The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000. Purpose: The FIRM is the basis for floodplain management, mitigation, and insurance activities for the National Flood Insurance Program (NFIP). Insurance applications include enforcement of the mandatory purchase requirement of the Flood Disaster Protection Act, which "... requires the purchase of flood insurance by property owners who are being assisted by Federal programs or by Federally supervised, regulated or insured agencies or institutions in the acquisition or improvement of land facilities located or to be located in identified areas having special flood hazards," Section 2 (b) (4) of the Flood Disaster Protection Act of 1973. In addition to the identification of Special Flood Hazard Areas (SFHAs), the risk zones shown on the FIRMs are the basis for the establishment of premium rates for flood coverage offered through the NFIP. The DFIRM Database presents the flood risk information depicted on the FIRM in a digital format suitable for use in electronic mapping applications. The DFIRM database is a subset of the Digital FIS database that serves to archive the information collected during the FIS.

For the purposes of the NFIP, changes to the flood risk information published by FEMA may only be performed by FEMA and through the mechanisms established in the NFIP regulations (44 CFR Parts 59-78). These digital data are produced in conjunction with the hardcopy FIRMs and generally matches the hardcopy map exactly. However the hardcopy flood maps and flood profiles are the authoritative documents for the NFIP. Acknowledgement of FEMA would be appreciated in products derived from these data.

The published effective FIRM and DFIRM maps are issued as the official designation of the SFHAs. As such they are adopted by local communities and form the basis for administration of the NFIP. For these purposes they are authoritative. Provisions exist in the regulations for public review, appeals and corrections of the flood risk information shown to better match real world conditions. As with any engineering analysis of this type, variation from the estimated flood heights and floodplain boundaries is possible. Details of FEMA's requirements for the FISs and flood mapping process that produces these data are available in the Guidelines and Specifications for Flood Hazard Mapping Partners. Attribute accuracy was tested by manual comparison of source graphics with hardcopy plots and a symbolized display on an interactive computer graphic system. Independent quality control testing of FEMA's DFIRM database was also performed. 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 FIS report that accompanies this DFIRM database. Users should be aware that BFEs shown in the S_BFE table 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 must be used in conjunction with the FIRM for purposes of construction and/or floodplain management. The 1-percent-annual- chance water-surface elevations shown in the S_XS table match the regulatory elevations shown in the FIS report. Logical_Consistency_Report: When FEMA revises an FIS, adjacent studies are checked to ensure agreement between flood elevations at the boundaries. Likewise flood elevations at the confluence of streams studied independently are checked to ensure agreement at the confluence. The FIRM and the FIS are developed together and care is taken to ensure that the elevations and other features shown on the flood profiles in the FIS agree with the information shown on the FIRM. However, the elevations as shown on the FIRM are rounded whole-foot elevations. They must be shown so that a profile recreated from the elevations on the FIRM will match the FIS profiles within one half of one foot. Completeness_Report: Data contained in the DFIRM Database files reflect the content of the source materials. Features may have been eliminated or generalized on the source graphic, due to scale and legibility constraints. With new mapping, FEMA plans to maintain full detail in the spatial data it produces. However, older information is often transferred from existing maps where some generalization has taken place. Flood risk data are developed for communities participating in the NFIP for use in insurance rating and for floodplain management. Flood hazard areas are determined using statistical analyses of records of river flow, storm tides, and rainfall; information obtained through consultation with the communities; floodplain topographic surveys; and hydrological and hydraulic analysis. Both detailed and approximate analyses are employed. Generally, detailed analyses are used to generate flood risk data only for developed or developing areas of communities. For areas where little or no development is expected to occur, FEMA uses approximate analyses to generate flood risk data. Typically, only drainage areas that are greater than one square mile are studied.

For this revision, the hydrologic and hydraulic analyses for the Connecticut River were prepared by ENSR International, East Coast Mapping, CR Environmental, Green International, Cold Regions Research and Engineering Laboratory for FEMA, under contract EMB-2001-CO-0627. This work was completed on September 29, 2002. Base map information shown on this FIRM was derived from U.S. Geological Survey Digital Orthophoto Quadrangles produced at a scale of 1:12,000 from photography dated 1998 or later. These images were recast by the New Hampshire Geographically Referenced Analysis and Information Transfer System (NH GRANIT) onto the New Hampshire State Plane coordinate system. The projection used in the preparation of this map was New Hampshire State Plane, FIPSZONE 2800. The horizontal datum was NAD 83, GRS80 spheroid. This FIS covers the incorporated areas of the geographic area of the Cheshire County, New Hampshire. All or portions of the following flooding sources were studied by detailed methods: Ashuelot River, Ash Swamp Brook, Beaver Brook, Black Brook, Black Reservoir Outlet Stream, Blanchard Brook, Branch River, Cold River, Connecticut River, Contoocook Lake, Contoocook River, Hayward Brook, Mead Brook, The Meadows Overland Flow, Minnewawa Brook, Mirey Brook, Mountain Brook, Mountain Brook Reservoir, North Branch Millers River, Otter Brook, Pauchaug Brook, Pool Pond, Robbins Brook, Rixford Brook, Roaring Brook, South Branch Ashuelot River, Snow Brook, Sprague Brook, Wheelock Brook For this countywide FIS, the portion of the Connecticut River from approximately 80 feet downstream of Vernon Dam to the Cheshire County-Sullivan County boundary was restudied by detailed methods. The study area includes the Connecticut River and its backwater affecting portions of Ashuelot River, Blanchard Brook, Cold River, and Sprague Brook, extending no further than approximately 0.95 mile upstream of their confluence with the Connecticut River. For the unrevised portion of the Connecticut River, from the county boundary to approximately 80 feet downstream of Vernon Dam, the effective Town of Hinsdale FIS was used. Limits of detailed study are indicated on the Flood Profiles and on the FIRM. The areas studied by detailed methods were selected with priority given to all known flood hazard areas and areas of projected development and proposed construction. This revision incorporated a LOMR issued by FEMA dated September 25, 2003, in the City of Keene. The LOMR reflects a more detailed analysis that is described as The Meadows Overland Flow, from the intersection of State Routes 9, 10, and 12 to the point of divergence from Ash Swamp Brook. All or portions of the following streams were studied by approximate methods: Ash Brook, Ashuelot River, Bear Meadow Brook, Beaver Brook, Bell Brook, Black Brook, California Brook, Clapp Pond, Damon Reservoir, Falls Brook, Forbush Brook, Hammond Brook, Hayward Brook, Hog Tongue Brook, Island Pond, Kilburn Brook, Lamson Brook, Lily Pond, Liscom Brook, Martin Brook, Meetinghouse Pond, Minnewawa Brook, Mountain Brook, New Run Brook, Perry Brook, Robbins Pond, Shaker Brook, Spectacle Pond, Sprague Book, Swanzey Lake, Tophet Swamp, Wheelock Brook, White Brook, Wilson Pond, and Wright Brook, several unnamed swamps and flooding sources, an unnamed tributary to the Connecticut River, and Tributary A to the Ashuelot River. Approximate analyses were used to study those areas having a low development potential or minimal flood hazards. The scope and methods of study were proposed to, and agreed upon by, FEMA and Cheshire County.
