INTRODUCTION
The State of North Carolina, through the Federal Emergency Management Agency’s
(FEMA’s) Cooperating Technical Community partnership initiative, has been designated
as the nation’s first Cooperating Technical State (CTS). As a CTS, the State has
assumed primary ownership and responsibility for updates of the National Flood
Insurance Program’s (NFIP) Flood Insurance Rate Maps (FIRMs) for all North Carolina
communities. This role has traditionally been fulfilled by FEMA.
North Carolina faces extreme hazard and consequence from hurricanes and flooding.
Since 1989, there have been 21 federally declared disasters in North Carolina. Damages
from Hurricane Floyd alone have reached $3.5 billion. As a result of Hurricane Floyd,
4,117 uninsured and under-insured homes were destroyed. Table 1 below shows the
number of flood claims and repetitive loss claims in the Little Tennessee River Basin
between the years of 1978 and 2003. The State’s vulnerability to hurricanes and
flooding make it crucial that communities and property owners have accurate, up-to­
date information about the flood risk. The updated DFIRMs produced through this
Program will help to protect the lives and property, and contribute to the general well
being, of North Carolina citizens.

Why the State of North Carolina Created the Floodplain Mapping Program
There are several reasons why the State has initiated this Program; these include the
following:
•
•
•
•
Approximately 55% of North Carolina FIRMs were at least 10 years old.
Approximately 75% of North Carolina FIRMs were at least 5 years old.
FEMA’s mapping budget is finite; on average, North Carolina received only one
updated flood study for one county per year.
Many counties and communities have indicated that they do not have the resources to take on this responsibility. Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 1
North Carolina Floodplain Mapping Program Cooperating Technical State Components of the North Carolina Floodplain Mapping Program
The North Carolina Floodplain Mapping Program involves the following:
•
•
•
Acquisition of high-resolution topographic data and development of accurate Digital
Elevation Models (DEMs.)
Development of up-to-date, accurate flood hazard data and floodplain mapping.
Production of seamless digital FIRM coverage statewide:
DFIRMs will be produced on a statewide basis where all counties and
incorporated communities are seamlessly shown across one set of state maps.
Digital Orthophoto Quadrangles (DOQs), produced in partnership by the State
of North Carolina and the U.S. Geological Survey (USGS), will be used as the
primary base map. In areas where there is a locally produced base map that is
more current or accurate than the DOQs, the locally developed map may be
used to supplement or in place of the DOQs as the base.
- Flood Elevations on the DFIRMs will be converted to the North American
Vertical Datum of 1988 (NAVD 88).
The North Carolina Floodplain Mapping Program, administratively located in the North
Carolina Division of Emergency Management (NCEM) oversees and manages the
Program. NCFMP will work closely with several other state agency partners (North
Carolina Geodetic Survey [NCGS], Center for Geographic Information and Analysis
[CGIA], and the Floodplain Management Branch) to ensure quality map production. In
the production of the Basin Plan, NCFMP has worked in close cooperation with the
Floodplain Management Branch of the NCEM to ensure that all flood hazards and NFIP
issues are addressed. Additionally, after the updated flood data and maps are
produced, NCFMP coordinates with Floodplain Management to conduct training and
outreach to assist communities in utilizing the new data and maps to implement
floodplain management and hazard mitigation activities.
The North Carolina Floodplain Mapping Program has also implemented a state-of-the­
art, dynamic Floodplain Mapping Information System (FMIS) to analyze, maintain, and
archive maps and associated flood hazard data. The FMIS also serves to present and
distribute the mapping data and associated reports to the public via the Internet without
the user needing to have sophisticated Geographic Information System (GIS) software.
An additional component of the Program is a real-time flood forecasting and inundation
mapping capability. The North Carolina Flood Warning System is currently being piloted
in the Tar-Pamlico and Neuse River Basins.
The development of topographic and flood data and production of statewide digital
FIRM panels will have three phases (Figure 1): (1) scoping, (2) flood map production,
and (3) Community Review and Due Process (post-preliminary process).

Flood Mapping Program Funding and Work Plan
In August 2000, the North Carolina General Assembly allocated $42.8 million to the
Floodplain Mapping Program. FEMA has contributed an additional $30.65 million toward
the Program as well as in-kind contribution of engineering, mapping, and program
management services. The State has also worked with other Federal partners to secure
additional needed funding. Based on the General Assembly’s directive, work began on
the six eastern river basins as shown in Figure 2 (Phase I—Cape Fear, Lumber, Neuse,
Pasquotank, Tar-Pamlico, and White Oak). Work was initiated on six additional river
basins in 2003 (Phase II—Chowan, Roanoke, Yadkin, Catawba, Watauga, and New).
Work on the remaining five basins (Phase III—Broad, French Broad, Little Tennessee,
Hiawassee, and Savannah) began in the summer of 2005, in which the General
Assembly of North Carolina provided an additional $10 million.

Program Benefits
The North Carolina Statewide Floodplain Mapping Program will provide many benefits to
North Carolina communities, property owners, and citizens. These include:
•
The updated flood hazard data will provide current, accurate information for
North Carolina communities and property owners to make safe siting and design

decisions when rebuilding from flooding disasters, building new structures and
infrastructure, and retrofitting existing structures.
The use of the updated data by communities for floodplain management will dramatically reduce long-term flood losses to the State of North Carolina, its communities, and its citizens. Updated flood hazard data will alert those at risk to flooding of the need to purchase flood insurance protection. It will be faster and more cost effective to update DFIRMs.
Current, updated base maps and the digital format of the FIRMs will allow users
to make more efficient, precise flood risk determinations.
The resultant DFIRMs will be the official NFIP maps; these DFIRMs will also be
used by communities for floodplain management purposes.
The digital format of the DFIRMs will allow use with GIS for analysis and planning. The digital Floodplain Mapping Information System will allow online access to all
map users 24 hours a day without requiring sophisticated GIS software.
The DEMs being developed will be useful for almost any engineering or planning
application, such as site design, storm-water management, transportation
planning and design, and spill response.
This report summarizes and provides details about the scoping phase that was
completed for the Little Tennessee River Basin and how the results of this scoping effort
were used to generate a plan for developing updated flood data and statewide DFIRMs
for counties and communities located within the Little Tennessee River Basin. This
report also describes the process and schedule for completing the map production and
community review phases.

North Carolina Floodplain Mapping Program Cooperating Technical State II. LITTLE TENNESSEE RIVER BASIN DESCRIPTION
The Little Tennessee River Basin is located within the Blue Ridge Province of the
Appalachian Mountains of western North Carolina and east-central Tennessee. Roughly
75% of its land area is situated in Tennessee, but its headwaters are in northern
Georgia and the western North Carolina Mountains. It is bordered to the south and west
by the Hiwassee and Savannah River Basins, and it is bordered to the north and east by
the French Broad River Basin. The Little Tennessee River Basin covers approximately
1,800square miles. It is located in the Blue Ridge/Appalachian Mountains region of
North Carolina. Figure 3 below shows the location of the North Carolina counties within
the Little Tennessee River Basin.
Figure 3. Little Tennessee River Basin Vicinity Map
Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 5
North Carolina Floodplain Mapping Program Cooperating Technical State The Little Tennessee River Basin is not large in land area, but does contain more than
2,500 miles of streams, and 18,000 acres of lakes, and contains three subbasins: the
Upper Little Tennessee River subbasin, the Tuckasegee River subbasin, and the Lower
Little Tennessee River subbasin.
The total distance of freshwater flooding sources sums to equal approximately 2,565
miles in the Little Tennessee River Basin. The Little Tennessee River Basin is comprised
of portions or all of Cherokee, Clay, Graham, Jackson, Macon, and Swain counties. It is
also composed of 9 municipalities including Bryson City, Dillsboro, Forest Hills, Franklin,
Highlands, Robbinsville, Santeetlah, Sylva, and Webster. Additionally, most of the
Eastern Band of Cherokee Indians reservation lies within the Little Tennessee River
Basin, including six communities: Big Cove, Birdtown, Painttown, Snowbird, Wolftown,
and Yellowhill. According to the 2000 Census data, the population of the Little
Tennessee River Basin is approximately 79,493, and is expected to increase by 31% by
2020, driven primarily by second homes and retirees. There is also a significant
seasonal growth in the basin due to recreation and tourism.
Nearly 89% of the basin is forested with much of it located within the Great Smoky
Mountains National Park or the Nantahalah National Forest; about one-half of the Little
Tennessee River Basin is federally owned. Steep slopes limit the land area suitable for
development and crop production. The Little Tennessee River Basin supports a large
variety of aquatic species, including rare fish, mussels, and insects, as well as rare
wetland communities, such as spray cliffs and mountain bogs.
Clay, Cherokee, Jackson and Macon Counties are all located partially within the Little
Tennessee River Basin. Table 2 below summarizes the counties and communities located
partially or entirely within the Little Tennessee River Basin and their current NFIP
participation and mapping status.

SCOPING PHASE FOR THE LITTLE TENNESSEE RIVER BASIN
The State worked closely with FEMA and Dewberry, to complete the scoping phase for
the Little Tennessee River Basin counties and communities in the Spring of 2006. Stated
simply, “scoping” involves determining what areas are floodprone and need to have
flood hazard data developed, what methods will be used to generate that hazard data,
and how the data will be presented on the DFIRMs. For the Little Tennessee River
Basin, the comprehensive scoping phase entailed:
•
•
•
•
•
•
Researching and inventorying available elevation, flood hazard, and digital base
map data that may be useful for preparing updated DFIRMs;
Assessing existing flood hazard data (for example: flood elevation profiles, floodplain boundaries, or floodways) on effective FIRMs for adequacy; Providing outreach to, and receiving input from, counties and communities regarding their needs for updated DFIRMs; Identifying data that needs to be developed or acquired, such as digital base maps, DEMs, or field surveys of stream channels, and hydraulic structures Determining the proposed scales and paneling scheme for statewide DFIRM production; and Developing a schedule for completion of updated flood hazard data and digital
FIRM production.
Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 7
North Carolina Floodplain Mapping Program Cooperating Technical State For flooding sources within the basin, the flood hazard data from the effective FIRMs
were assessed for adequacy in consultation with the impacted counties and
communities. For areas where the existing flood hazard data was deemed to be
inadequate or outdated, a priority level was established and the most appropriate
method of developing updated data was selected based on the:
•
•
•
Type and extent of man-made and natural changes within the floodplain and/or
watershed;
Quality of data available; and
Existing and/or proposed levels of development affected by the flooding source.

North Carolina Floodplain Mapping Program Cooperating Technical State Step 1—Initial Research and Community Coordination
The State held two central “kickoff” meetings in 2005 with county and community
floodplain administrators, engineers, and planners on August 8 and 9 in Cullowhee and
Marion, North Carolina, respectively. The objectives of the meetings were to overview
the State’s CTS Agreement with FEMA and the North Carolina Floodplain Mapping
Program, inform the floodplain administrators of the process that will be followed to
develop updated mapping, and encourage them to be an active participant in the
process. A questionnaire regarding the communities’ mapping needs was mailed prior
to the meeting and distributed to those community representatives in attendance. This
questionnaire contained pointed questions designed to help each community
systematically ascertain its flood mapping needs. The county and municipal officials
were encouraged to complete the questionnaire and submit it back to the NCFMP either
digitally via e-mail or via hardcopy. Technical support was available for completion of
the questionnaire through the State.
Completed questionnaires were received by the State from the following counties and
communities in the Little Tennessee River Basin: Cherokee County, Jackson County,
Town of Robbinsville, Town of Dillsboro, Town of Franklin, Town of Highlands, Town of
Sylva, and the Town of Webster.
Additionally, the State completed research of community mapping needs as per its
September 1999 Cooperating Technical Community agreement with FEMA, “Assessment
of Community Mapping Needs.” Further, FEMA and Dewberry conducted research of
effective Flood Insurance Study (FIS) and FIRM information and other relevant data
available for each community in the FEMA Flood Mapping Archives and FEMA’s Mapping
Needs Update Support System database. This database contains information on
community mapping needs collected over the past few years through community
surveys.
As part of the initial research, the State and Dewberry also evaluated post-Hurricane
Floyd data, such as gage information, high-water marks, and inundation mapping,
obtained from FEMA, the U.S. Army Corps of Engineers, and the USGS. The purpose of
this evaluation was to identify areas where actual flooding elevations and inundation
limits experienced did not match the flood hazard data in the effective FIS and FIRM,
thereby indicating a mapping need.

Date: June 8, 2007
Page 10
North Carolina Floodplain Mapping Program Cooperating Technical State U.S. Geological Survey Gage Data
Up-to-date analyses for stream gages located in the Little Tennessee River Basin were
obtained from the USGS. The revised gage analyses were compared with effective FIRM
information to determine the need for restudy of the flooding sources on which these
gages are located. As part of this assessment, the 1% annual chance (100-year)
discharge and water-surface elevation were compared. Table 3 outlines this information
for all stream gages in the Little Tennessee River Basin.

The results of the initial research and responses to the community questionnaires were
entered into a GIS-enabled scoping database: Mapping and Engineering Needs
Community Assessment (MENCA). This database was used to generate “Initial Scoping
Projects” for each community; these projects were used to conduct the Initial Scoping
Meetings (Step 2).
Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 11
North Carolina Floodplain Mapping Program Cooperating Technical State Step 2—Initial Scoping Meetings
The State held meetings with each of the four counties (Graham, Jackson, Macon, and
Swain) that contain the vast majority of area within the Little Tennessee River Basin to
present the results of the initial research to the county and its communities and to
discuss their flood mapping needs. Elected officials, floodplain administrators,
emergency managers, and GIS staff were invited from the county and each incorporated
community, including those communities that do not participate in the NFIP. The
meetings were held at the Southwestern Community College in Sylva on November 9,
2005, and the Macon County Courthouse in Franklin on November 10, 2005, due to their
central location and ease of accessibility within the river basins jurisdictions. Dewberry
staff attended to provide program and technical support during the meetings. NCEM
Floodplain Management Branch staff attended the meetings to exchange contact
information with community Floodplain Administrators, establish contact with non­
participating communities, and distribute copies of the current North Carolina model
Flood Damage Prevention Ordinance. Table 3 summarizes the initial scoping meeting
dates with each community. Meeting attendance sheets are included as Appendix A.
Please note that portions of some counties in the Little Tennessee River Basin
(Cherokee, Clay, Macon, and Jackson) are situated in the adjoining Hiwassee and/or
Savannah River Basins. The initial scoping meetings for all counties that comprise the
Little Tennessee River Basin were conducted on a countywide basis and covered all
areas of each county and community in the county irrespective of the basin. There are
no studied streams within the Clay and Cherokee County portions of the Little
Tennessee River Basin since a majority of these counties lie within the Hiwassee River
Basin. Local officials did not have any floodplain mapping requests for the portions of
Clay and Cherokee Counties that extended into the Little Tennessee River Basin. Table 4
contains a list of communities with the location and date of initial scoping meetings held
for each community. Only those communities located entirely or partially within the
Little Tennessee River Basin are listed in Table 4.

At the initial scoping meetings, the State (NCFMP), NCEM Floodplain Management
Branch, and Dewberry representatives met individually, or in groups, with the county
and its incorporated communities’ representatives to:
•
•
•
Provide a brief overview of the Floodplain Mapping Program purpose, objectives,
and goals;
Review the research results for each community using the Initial Scoping Package; Discuss the community’s mapping needs and response to the questionnaire; and
Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 13
North Carolina Floodplain Mapping Program Cooperating Technical State •
Identify available local data such as base maps, topographic data, ongoing studies, etc. In assessing the communities’ flood mapping needs, emphasis was placed on:
•
•
•
•
•
•
Areas of future development;
New or proposed crossings, encroachments, and flood controls;
Historically flooded areas;
Out-of-date or inadequate data on current FIRMs;
Existing data mismatches with contiguous communities; and
Out-of-date FEMA analyses (detailed or approximate).
For flooding sources identified in the meeting as having a flood mapping need, the
community was asked to provide input on proposed study analysis methods and
priorities.
Appendix B contains tables summarizing the community-identified flood mapping needs,
suggested type of study, and priorities for each community within the Little Tennessee
River Basin. Attachments 1A through 1D depict these community-identified needs and
priorities.
Also, as part of the initial scoping effort, CGIA met with county GIS staff to inventory the
availability of local GIS data to identify potential base map data resources for the
Floodplain Mapping Program. Information collected from the survey form was entered
into MENCA for each Phase III county.
Step 3—Draft Basin Plan
Based on the results of the Initial Scoping Meetings, the State synthesized the research
and the community input. These results were used to develop the Draft Basin Plan for
developing updated flood hazard data for the basin and for producing statewide DFIRM
panels for the affected counties and communities within the Little Tennessee River
Basin.
Section IV and the Appendices of the Draft Basin Plan included a list of flooding sources
to be updated within the basin, including the technical method of update (detailed,
limited detailed, or redelineation) and reach limits and stream miles to be updated.
Section IV also included a comprehensive list of counties for which statewide DFIRM
panels will be produced including digital base map source to be used and proposed
DFIRM paneling and tiling scheme. Lastly, Section IV also included a projected schedule
for completing the basin studies and statewide preliminary DFIRMs.
Step 4—Final Scoping Meetings
The draft Little Tennessee River Basin Plan was sent to affected counties and
communities and posted on the State’s website on March 23, 2006. Subsequently, after
Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 14
North Carolina Floodplain Mapping Program Cooperating Technical State a 30-day review period, the State would typically holds a Final Scoping meeting for the
Little Tennessee River Basin counties and communities.
The communities’ Chief Elected Officer, floodplain administrators, planners, Engineers,
GIS staff, building and zoning officials would typically be invited from each county and
incorporated community in the basin for the Final Scoping Meetings.
The objective of the final scoping meeting is for the State to overview the Draft Basin
Plan, including the proposed scope, schedule for the project, and provide an opportunity
for additional county and community input or suggested changes to the Draft Basin
Plan. Typically, individual meetings, for each county would be scheduled for community
leaders to meet with representatives from the State and Dewberry. However, in this
case, jurisdictions were contacted by letters and phone calls in order to confirm the
jurisdictions satisfaction and acceptance of the Draft Basin Plan and the proposed scope
of flood hazard data studies.
This Final Basin Plan summarizes the comments and/or feedback received from these
letters and phone calls.
Step 5—Final Basin Plan
After the jurisdiction’s acceptance of scope was verified, the Draft Basin Plan was
revised, as necessary, to produce this Final Basin Plan. The Final Basin Plan contains
specific information regarding comments that were received and how the Draft Basin
Plan was revised and why.
The State then requested that its Flood Mapping Contractor prepare a technical and cost
proposal to execute the components of the revised draft Little Tennessee River Basin
Plan. After negotiations between the State and the Flood Mapping Contractor if the cost
estimate indicates that the Basin Plan can be executed within the State’s available
budget for the Little Tennessee River Basin, the Basin Plan will be finalized. However, if
the negotiated cost estimate indicates that the Basin Plan cannot be executed within the
State’s available budget, the State may have to modify the scope of the project.
Once the Little Tennessee River Basin Plan is finalized, the Final Basin Plan will be
posted on the State website, www.ncfloodmaps.com, with a description and explanation
of any changes made from the Draft Basin Plan.

ELEVATION AND FLOOD DATA DEVELOPMENT AND DIGITAL FIRM
PRODUCTION FOR THE LITTLE TENNESSEE RIVER BASIN
The State’s flood mapping contractor will develop digital elevation data, conduct
engineering flood hazard analyses, and prepare floodplain delineations for the flooding
sources in the Little Tennessee River Basin and produce statewide preliminary DFIRMs
for the affected communities within the Little Tennessee River Basin.
Figure 5 shows how the base map, topographic data, and flood data will be used to
“build” a DFIRM. Each component is discussed further in the following sections.

Figure 5. Components of a Digital FIRM
Base Map
Locally produced digital orthophotography will be used as the base map for statewide
DFIRM production, provided that it meets FEMA’s base map standards. If local imagery
is not available, the U.S. Geological Survey (USGS) Digital Orthophoto Quadrangles
(DOQs), based on 1998 aerial photography, will be used. The base maps will be
supplemented with stream and river centerlines, shoreline, political boundaries, and road
name data from other sources; this may include locally available GIS data. The specific
local GIS data to be used to supplement the DOQs will be determined on completion and
assessment of the CGIA’s GIS surveys as discussed in Section III of this Final Basin Plan.
Topographic Data
Watershed Concepts, under contract with the State, acquired digital topographic data of
the Little Tennessee River Basin using airborne Light Detection and Ranging (LIDAR).
This LIDAR data was acquired during the Fall 2005 flying season.
The topographic data satisfies a vertical root-mean-square error (RMSE) accuracy
standard of ±25 cm (±0.8 feet) accuracy at the 95% confidence limit (or roughly
“equivalent” to a 2.2 foot contour interval map) in floodplain areas. All elevations are
Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 16
North Carolina Floodplain Mapping Program Cooperating Technical State referenced to the NAVD 88 and reflect orthometric heights. Variably spaced, bare-earth
digital topographic data in ASCII point file format is combined with imagery (either flown
concurrently with the LIDAR data or using existing digital orthophotos) to establish a
Triangulated Irregular Network (TIN) to include selected breaklines used for hydraulic
modeling. Furthermore, uniformly spaced Digital Elevation Models (DEMs), with 20 ft. x
20 ft. or 50 ft. x 50 ft. post spacing, are generated in multiple file formats.
These topographic data will be primarily used for floodplain modeling and mapping for
counties and communities in the Little Tennessee River Basin (described below).
However, the data will also be useful for other State and county engineering and
planning applications using ARC/INFO and other GIS software and will be available
through the State’s online Information Management System described earlier in this
plan. It is planned for these data to be available online in 2007.
Flood Hazard Data
In developing flood hazard data for each of the flooding sources in the Little Tennessee
River Basin the State’s Flood Mapping Contractor will utilize one of four options
available. These are described below. All flood elevations will be referenced to the
NAVD 88. All analyses and mapping will comply with FEMA’s regulations, guidelines,
and specifications for NFIP mapping.
1. Detailed Study—Riverine
This method entails using the Triangulated Irregular Network (TINs), supplements them
with field surveys for channel bathymetry, bridge/culvert opening geometry, and
channel and floodplain characteristics, to conduct fully detailed hydrologic and hydraulic
analyses and floodplain mapping. This will include analyses of the 10%, 2%, 1%, and
0.2% annual chance flood peak discharges, water-surface elevations, profiles, and
determination of a floodway. Riverine areas studied in detail will be designated as Zone
AE on the updated DFIRMs. Flood profiles and base flood elevations will be referenced
to NAVD 88.
Table 5 summarizes the riverine flooding sources and reach descriptions within the Little
Tennessee River Basin that will be studied using detailed methods. The estimated
number of hydraulic structures is an approximation of the number of culverts, bridges,
dams, and weirs along the reach to be studied in detail. These estimates were made
based on the number of major road crossings using CGIA data and from the flood
profiles in the current FIS report. Attachments 2A through 2D depict the specific
reaches to be studied in detail.

North Carolina Floodplain Mapping Program Cooperating Technical State 2. Redelineation
This method involves no new analyses; rather, the effective FIS and FIRM data will be
fitted to the updated base map using the new LIDAR-derived topographic data.
Floodways and cross section locations are digitized from the effective FIRMs and Flood
Boundary and Floodway Map. Flood profiles and base flood elevations are converted
from NGVD 29 to NAVD 88.
Areas where this technique is used will be designated as Zone AE on the updated
DFIRMs. This technique is useful for riverine and lacustrine flooding sources where the
effective FIS engineering analyses are adequate but the topographic data used to
delineate the floodplain boundaries is not sufficiently detailed or up-to-date.
The redelineation method will be used for all flooding sources within the Little
Tennessee River Basin that are currently studied in detail on current FIRMs and that are
not being restudied in detail as part of this Basin Plan. Appendix D depicts the specific
reaches to be redelineated.
3. Limited Detailed Study
This method entails using the TINs being produced as part of the North Carolina
Floodplain Mapping Program, without adding field-surveyed bathymetric or
bridge/culvert opening geometric data, to conduct hydrologic and hydraulic analyses. In
addition, this method does not include field surveys that determine specifics on channel
and floodplain characteristics. However, bridge and culvert opening data from North
Carolina Department of Transportation maintenance records is incorporated into the
hydraulic analysis models. Limited detailed study will result in the delineation of the 1%
annual chance floodplain boundaries and base flood elevations.
These will be
designated as Zone AE on the newly generated DFIRMs. Limited detailed study will also
determine widths of the non-encroachment area at all studied cross sections. The nonencroachment widths given at modeled cross sections can be used by communities to
enforce floodplain management ordinances that meet the requirement defined in 44 CFR
60.3(c)(10). This information will be provided in the Flood Insurance Study report to
facilitate local floodplain management.
The limited detailed study is a “buildable” product with a supporting engineering model
that can be upgraded to full detailed study at a later date by adding field-surveyed river
or stream channel and bridge/culvert opening geometric data.
All flooding sources currently designated as Zone A on the effective FIRMs that are not
being studied by detailed study methods will be reanalyzed using either the limited
detailed study method or the use of effective information method explained below. In
most cases, currently unmapped areas identified by communities as being a priority will
be studied by the limited detailed study method unless they are otherwise being studied
Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 22
North Carolina Floodplain Mapping Program Cooperating Technical State by detailed methods. Attachments 2A through 2D depict the specific reaches to be
studied using limited detailed methods.
Additionally, limited detailed study will be considered for unmapped flooding sources,
with an emphasis on those in developed areas with a drainage area larger than 1-square
mile. However, some floodprone areas with lesser drainage areas may also be mapped
based on known hazards, level of development, and community-identified needs.
Appendix E summarizes the flooding sources and descriptions within the Little
Tennessee Basin that will be studied using limited detailed methods.
4. Use of Effective Information
The study type "use of effective information" has been scoped for small effective Zone A
areas that are likely backwater “fingers” that will be replaced with the backwater from
the new or limited detailed study already scoped for the main stem. NCFMP will
evaluate these reaches on a case-by-case basis after the main stem is studied to
determine if the backwater replaces the effective Zone A “fingers” or if the tributary
should be studied by limited detailed study. If the area is completely covered by
backwater, NCFMP will not develop a "limited detailed" model for the reach. If the Zone
A area extends beyond backwater and the contributing upstream drainage area is
greater than 1-square mile in rural areas or 1/2-square mile in urban areas, NCFMP will
study the reach using "limited detailed" methods. If the contributing drainage area is
less than the urban and rural criteria, NCFMP will digitize the effective Zone A floodplain
and map as a shaded Zone X.
Several areas within the Little Tennessee River Basin, totaling 92.84 stream miles, have
been identified during scoping to be studied as Use of Effective Information.
Table 6 summarizes the estimated number of linear miles for each method to be applied
in the Little Tennessee River Basin. Attachments 2A through 2D depict the technical
methods to be applied to each flooding source within the Little Tennessee River Basin.

Variations from Community-Identified Needs and Priorities
In some instances, it was necessary to deviate from the needs and technical methods
identified by a county or community in developing this Final Basin Plan. The State used
a quantitative ranking system to address all community needs identified for detailed
study based on several factors. These factors included:
•
•
•
•
•
•
The age of the effective FIRM analyses (studies based on older analyses receive a
higher ranking)
Likely flood mapping impacts (the greater the anticipated change to the flood
elevation and/or floodplain boundary, the higher the ranking) Level of development (areas of more dense existing or anticipated development
receive a higher ranking, or conversely for flooding sources situated within public
lands such as a National Forest, where the potential for development is severely
limited will receive a lower ranking).
Historical flood information (if gage data, high-water marks, inundation mapping,
or community experience indicate a mapping problem, the higher the ranking)
Mismatches with contiguous communities (significant mismatches in flood
elevations and/or floodplain boundaries between adjacent communities receive a
higher ranking)
Whether any mitigation planning has been developed or is in the process of being
developed (if so, the community receives a higher ranking)
Appendix F summarizes the areas where the flood data development described above as
part of this Final Basin Plan differs from the community-identified needs and priorities.
Digital FIRMs
Using the base maps and flood hazard data described above, DFIRMs will be produced
in seamless statewide format, including the unincorporated areas of each county in the
Little Tennessee River Basin and their incorporated communities on one set of DFIRM
panels. The DFIRMs will depict flood hazard and related data (floodplain and floodway
boundaries, base flood elevations, cross sections, and flood insurance zone
designations) and non-engineering reference features (road names and locations,
stream and river centerlines, shorelines, corporate boundaries, airports, schools, and
bench marks).
Because some of the land area of these counties within the Little Tennessee River Basin
are at least partially located in adjacent river basins (Hiwassee and Savannah),
completion of the final effective statewide DFIRMs will be dependent on completion of
the basin studies for the adjacent basins. However, when the Little Tennessee River
Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 24
North Carolina Floodplain Mapping Program Cooperating Technical State Basin Study is completed, statewide preliminary DFIRMs will be issued for the portions
of counties and communities within the Little Tennessee River Basin. (The community
review and due process phases are discussed in more detail in Section V of this Final
Basin Plan.)
DFIRM panels will be tiled using the NCFMP tiling scheme and will be produced at either
1”=500’ (for panels with detailed study or urban areas) or 1”=1,000’ (for panels with
only limited detailed study or rural areas). Table 7 summarizes the number and scale of
DFIRM panels, the proposed schedule, and other basins affecting each county.

V. COMMUNITY REVIEW AND DUE PROCESS
As discussed in Section IV of this Basin Plan, when the Little Tennessee River Basin
Study is completed, statewide preliminary DFIRMs will be issued to the impacted
counties and communities for the portion of the county within the Little Tennessee River
Basin. As shown in Table 7 in Section IV, the statewide preliminary DFIRM panels for
the Little Tennessee River Basin are anticipated to be issued by 2008. Subsequently, a
preliminary DFIRM meeting will be held for county and community officials to present
the results of the Little Tennessee River Basin Study and statewide preliminary DFIRM
panels, answer questions, and explain administrative procedures. Shortly after the
preliminary DFIRM panels are issued, a statutory 90-day appeal period will be initiated
to allow counties, communities, and/or citizens to submit technical or scientific data to
FEMA and the State to refute or contest new or revised base flood elevations shown on
the preliminary DFIRMs and otherwise provide comments on the preliminary DFIRMs.
Any and all appeals will be evaluated and resolved by FEMA in close coordination with
the State, Dewberry, and the State’s Flood Mapping Contractor.
Final Basin Plan — Little Tennessee River Basin
Date: June 8, 2007
Page 25
North Carolina Floodplain Mapping Program Cooperating Technical State As the other basin studies impacting a county are completed, statewide preliminary
DFIRM panels will be issued for the remaining portion(s) of the county. A preliminary
DFIRM meeting will be held for those basins and the statutory 90-day appeal period will
be provided and all appeals will be evaluated and resolved.
After issuing preliminary DFIRM panels for all areas of a county and evaluating and
resolving all appeals and community comments, the statewide preliminary DFIRM panels
will be finalized. FEMA’s Map Service Center will print and distribute the official DFIRMs
to be used for flood insurance rating purposes. Additionally, the State will post the final
statewide DFIRMs on its Floodplain Mapping Information System for distribution and
access to communities and the public via the Internet.
During the community review and due process phase, many counties and communities
will need to update their floodplain management ordinances; the communities will be
given a 6-month period to adopt the updated DFIRMs and incorporate the DFIRMs into
their ordinances before the new DFIRMs become effective. The NCEM Floodplain
Management Branch and FEMA will coordinate this effort with the counties and
communities that need to update their ordinances.
