DIGITAL FLOOD INSURANCE RATE MAP DATABASE, SUSSEX COUNTY, NEW JERSEY
Dataset Identification:
Resource Abstract:
The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the
risk data. 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 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.

Use Constraints: The hardcopy FIRM and DFIRM and the accompanying FISs are the official designation of SFHAs and Base Flood
Elevations (BFEs) for the NFIP. 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.

Base map information shown on this FIRM was provided in digital format by the NJ Office of Information Technology (NJOIT),
Office of Geographic Information Systems (OGIS). This information was provided in both MrSID format (compressed 8-bit, 3-band,
RGB natural color, 5000' by 5000' tiles) and JPEG 2000 format (compressed 8-bit, 4-band RGB plus infrared, 5000' by 5000'
tiles) orthoimagery from photography dated March-May, 2007. The projection used in the preparation of this map was New Jersey
State Plane Coordinate System. The horizontal datum was NAD 83, GRS80 spheroid. This FIS covers the incorporated areas of

The FIS and FIRM are the basis for floodplain management, mitigation, and insurance activities for the National Flood Insurance
Program (NFIP). This FIS covers the incorporated area of Borough of Branchville, NJ. For this revision, Culvers Creek was
studied for the entire length a distance of approximately 0.8 miles. The Dry Brook was studied for the entire length a distance
of approximately 0.8 miles. Hydrologic and Hydraulic analyses were prepared by the Soil Conservation Service (SCS) for use
in a Floodplain Management Study of the Paulins Kill Watershed complied by the SCS in Conjunction with the NJDEP in 1983.For
Borough Branchville FIS, revised hydrologic and hydraulic analyses were prepared for FEMA by Leonard Jackson Associates under
Contract No. EMN-2002-RP-0018. This work was completed in April 2005. The projection used in this study was New Jersey State
Plane Coordinate System. The horizontal datum was NAD 83, GRS80 spheroid. All elevations used in this study are referenced
to the NAVD 1988. This FIS covers the incorporated areas of the geographic area of Borough of Branchville, New Jersey.

name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
The DFIRM Database consists of countywide vector files and associated attributes produced in conjunction with the hardcopy
FEMA FIRM. The published effective FIRM and DFIRM 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. Horizontal 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.

Completeness Commission
evaluation Method Description
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.

ConceptualConsistency
measure Description
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.
Data requests must include the full name of the community or county and the FIRM panel number(s) or the 7.5- minute series
quadrangle sheet area(s) covered by the request.
