SUBJECT: Nationwide Permit 33 Application for the proposed replacement of
Bridge No. 106 on SR 1309 (Lower Alarka Road/ Stephenson Branch
Road) over Alarka Creek, in Swain County. Federal Aid Project No.
BRZ-1309(2), State Project No. 82990401, TIP No. B-3701, WBS
Element 33241.1.1, Division 14.
Please find enclosed three copies of the Categorical Exclusion (CE) Document, as well as, the
Pre-construction Notification Form, permit drawings, and %i size plans for the above referenced
project-completed by the North Carolina Department of Transportation {NCDOT). The agency
proposes to replace Bridge No. 106, northeast of the existing alignment, with a 100-foot single
span steel girder bridge. Construction of the proposed project will require the installation of two
temporary rock work pads resulting in a total of 0.019 acre of temporary impacts to the existing
stream channel. There are no jurisdictional wetlands within the project study area.
Impacts to Waters of the United States
General Description
Alarka Creek is located in the Little Tennessee River Basin (sub-basin 04-04-02), and is
approximately 24 feet wide and 2.5 feet deep within the project study area. The NCDWQ
classifies Alarka Creek as Class "C Tr". A moratorium is being observed from November 1 -
April 15 to protect natural trout propagation and stocked trout. There are no High Quality Waters
(HQW), Water Supplies (WS-I or WS-II), or Outstanding Resource Waters occuring within 1.0
mile of the project study area. Alarka Creek is not designated as a National Wild and Scenic
River or a State Natural and Scenic River.
Permanent Impacts: There are no permanent impacts associated with this project.
TemporImpacts: There are 0.019 acre of temporary fill in surface water associated with this
project because of two temporary rock work pads. The work pads will be used to set the steel
girders of the new bridge in place. The work pads will be removed once construction is

complete. The stream and banks will then be restored to their original condition.
There are no utility impacts associated with this project.
Bridge-Demolition
The existing Bridge No. 106 was constructed in 1958. The three-span structure has a clear
roadway width of 20 feet which includes two travel lanes over the bridge. The superstructure
consists of an asphalt wearing surface over a timber deck on I-beams and the substructure
consists of timber caps and piles on concrete sills. Neither the superstructure nor the substructure
will create any temporary fill in the creek, however removal may create some disturbance in the
streambed. If the removal of the substructure does create disturbance in the streambed, a
turbidity curtain will be used to control sediment.
Federally Protected Species
Plants and animals with federal classifications of Endangered, Threatened, Proposed Endangered,
and Proposed Threatened are protected under provisions of Section 7 and Section 9 of the
Endangered Species Act of 1973, as amended. As of January 29, 2003, the Fish and Wildlife
Service (FWS) lists ten federally protected species for Swain County.

A survey for spotfin chub and sicklefin redhorse was completed on August 18, 2004 and again on
October 19, 2005 during which no specimens were found. As a result, USFWS has concurred
with a biological conclusion of No Effect for the Spotfin chub.
A mist net survey for Indiana bat was completed on July 1, 2004 during which no specimens were
observed. As a result, USFWS has concurred with a biological conclusion of No Effect.
Avoidance, Minimization, and Mitigation
Avoidance and Minimization: Avoidance examines all appropriate and practicable possibilities of
averting impacts to "Waters of the United States." The NCDOT is committed to incorporating all
reasonable and practicable design features to avoid and minimize jurisdictional stages;
minimization measures were incorporated as part of the project design. The use of best
management practices for construction should reduce impacts to plant communities.
The entire stream is being spanned, therefore eliminating any permanent impacts.
o The existing bridge is being used to maintain traffic until the new bridge is complete,
therefore eliminating the need for a temporary on-site detour.
Mitigation: There is no mitigation since there are no permanent impacts.
Regulatory Approvals
Section 404 Permit: All other aspects of this project are being processed by the Federal Highway
Administration as a "Categorical Exclusion" in accordance with 23 CFR § 771.115(b). The
NCDOT requests that these activities be authorized by a Nationwide Permit 33.
Section 401 Permit: We anticipate 401 General Certification number 3366 will apply to this
project. In accordance with 15A NCAC 2H .0501(a) we are providing two copies of this
application to the North Carolina Department of Environmental and Natural Resources, Division
of Water Quality, for their records.
We also anticipate that comments from the North Carolina Wildlife Resources Commission
(NCWRC) will be required prior to authorization by the Corps of Engineers. By copy of this
letter and attachment, NCDOT hereby requests NCWRC review. NCDOT requests that NCWRC
forward their comments to the Corps of Engineers.
Thank you for your assistance with this project. If you have any questions or need additional
information, please contact Megan Willis at [e-mail] or [phone].

site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.The entire stream is being
spanned, therefore no permaent impacts will result from this project.
VIII. Mitigation
Page 5 of 9
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmf;idc.btm1.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at

Gcotechnical Unit- Trout Stream
During subsurface investigations, equipment should be inspected daily and maintained to prevent
contamination of surface waters from leaking fuels, lubricants, hydraulic fluids, or other toxic
materials.
Construction Unit- Trout Stream
• A moratorium on in-water construction is to be enforced from November 1 to April 15.
• Temporary or permanent herbaceous vegetation should be planted on all bare soil within 15
days of ground disturbing activities to provide long term erosion control.
• All work in or adjacent to stream waters should be in a dry work area. Sandbags, rock berms
cofferdams, or other diversion structures should be used where possible to prevent excavation
in flowing water.
• If concrete is used during construction, a dry work area must be maintained to prevent direct
contact between curing concrete and stream water. Uncured concrete affects water quality
and is highly toxic to fish.
• Heavy equipment should be operated from the bank rather than in stream channels in order to
minimize sedimentation and reduce the likelihood of introducing other pollutants into
streams.
• Only clean, sediment-free rock should be used as tempor?.y fill (causeways), and should be
removed without excessive disturbance of the natural stream bottom when construction is
completed.
Right of Way Branch -Great Smokey Mountain Railroad (For your Information)
Early coordination with the Great Smokey Mountain Railroad indicates that they have serious
concerns regarding the aesthetic impacts that this project will have to their viewshed along the
project limits. Among those concerns is the clearing of the trees along the project area and the
exposure of powerlines currently hidden by the trees as well as the view that will be opened. The
final project footprint can not be known until the Hydraulics Unit adds their information to the
project design. It is anticipated that the Right of Way Unit will pick up with coordination and
begin negotiation regarding these issues during Right of Way Acquisition.
Project Development Engineer/Office of Natural Environment - T&E Species Concerns
T&E updates including Spotfin chub, Appalachian elktoe, Littlewing pearly mussel and Virginia

INTRODUCTION: Bridge No. 106 is included in the latest approved North Carolina
Department of Transportation (NCDOT) Transportation Improvement Program and is eligible for
the Federal-Aid Bridge Replacement and Rehabilitation Program. The location is shown in
Figure 1. No substantial environmental impacts are anticipated. The project is classified as a
Federal "Categorical Exclusion".
1. PURPOSE AND NEED STATEMENT
Bridge Maintenance Unit records indicate the bridge has a sufficiency rating of 26.7 out of a
possible 100 for a new structure. With an overall structural appraisal of 2 and a substructure
rating of 4 the bridge is considered to be structurally deficient. With a deck geometry appraisal
of 4 the bridge is considered to be functionally obsolete. For both reasons of structural
deficiency and functional obsolescence Bridge No. 106 is eligible for federal replacement* funds.
The replacement of this inadequate structure will result in safer traffic operations.
II. EXISTING CONDITIONS
The project is located in south central Swain County (see Figure 1). The area is rural and largely
undeveloped with scattered residences. The Great Smokey Mountain Railroad runs parallel to
SR 1309 to the north (see Figure 2).
SR 1309 is classified as a rural minor collector in the Statewide Functional Classification System
and it is not a National Highway System Route. This route is not a designated bicycle route and
there is no indication that an unusual number of bicyclists use this roadway.
The current traffic volume of 500 vehicles per day (VPD) is expected to increase to 900 VPD by
the year 2025. The projected volume includes one-percent truck-tractor semi-trailer (TTST) and
two- percent dual-tired vehicles. There is no posted speed limit and is therefore 55 miles per
hour by statute in the project area.
In the vicinity of the bridge, SR 1309 has a 20-foot pavement width with 4-foot grass shoulders.
The roadway is in a sage vertical curve through the project area. The existing bridge is in a
reverse horizontal curve. The roadway is situated approximately 15 feet above the streambed.
Bridge No. 106 is a three-span structure. The superstructure consists of an asphalt-wearing
surface over a timber deck on I-beams. All bents utilize timber caps and piles on concrete sills.
The existing bridge (see Figure 3) was constructed in 1958. The overall length of the structure is
91 feet. The clear roadway width is 24 feet. The posted weight limit on this bridge is 8 tons for
single vehicles and 8 tons for TTST's..
There is an aerial power line crossing diagonally over the bridge. Utility impacts are anticipated
to be low.
There have been no accidents reported in the vicinity of Bridge No. 106 during a check of a
recent three-year period.
III. ALTERNATIVES
A. Project Description
The replacement structure will consist of a 210-foot long bridge. The bridge will be of sufficient
width to provide for two 11-foot lanes with 3-foot offsets on each side.
The roadway grade of the new structure will be approximately the same as the existing facility at
this location.
The existing roadway approaches will be widened to a 22-foot pavement width to provide two
11-foot lanes. Six-foot grass shoulders will be provided on each side. This roadway will be
designed as a rural minor collector to meet the general criteria (including shoulder and lane
widths) for a 60-mile per hour design speed.
B. Reasonable and Feasible Alternatives
The one alternative for replacing Bridge No. 106 that was studied is described below.
Bridge No. 106 will be replaced on new alignment with the new bridge approximately 60 feet
north from the existing structure (See Figure 2). The new alignment will be approximately 1000
feet long. Traffic will be maintained on the existing bridge during the construction period.
The design speed for the project should ideally be 60 miles per hour. Roadway and shoulder
widths along with guardrail lengths will meet these criteria. However a design exception will be
required for vertical and horizontal curvature which will only meet a 30-mile per hour design.
C. Alternatives Eliminated From Further Consideration
The "do-nothing" alternative will eventually necessitate closure of the bridge. This is not
acceptable due to the traffic service provided by SR 1309.
Timber structures typically do not last beyond 30 to 40 years of age due to the natural
deterioration rates of wood. Rehabilitation of a timber structure is generally practical only when
a few members are damaged or prematurely deteriorated. However, past a certain degree of
2
deterioration, timber structures become impractical to maintain and are programmed for
replacement. Bridge No. 106 is beyond the point of rehabilitation being practical.
According to the Draft NCDOT Offsite Detour Guidelines, a project with significant constraints
and duration of 8 month-, rnnlrl have a maximum-delay' o inutes-resulting-fr-on}-an-offsite-
detour. For this project there are no constraints suggesting that an offsite detour is imperative.
The delay for the average road user would be 16 minutes. For these reasons, an offsite detour
has been ruled out.
Replacing the bridge on the existing location utilizing an onsite detour was discussed during the
scoping meeting and ruled out due in consideration that the impacts would be the same and the
additional cost associated with building a detour structure would be significant. There are no
compelling reasons to put the replacement structure on the existing location.
Replacing the bridge on new alignment to the south was considered and ruled out due to the
limitations of topography and access. Access to the driveway on the southeast corner of the
bridge would be very difficult to maintain without dramatic alteration to the mountainside.
D. Preferred Alternative
Bridge No. 106 will be replaced on new alignment as shown in Figure 2. This alignment is
recommended because it is the only practical alternative for replacing the bridge. Impacts to the
natural and human environments are minimal.
The NCDOT Division 14 Engineer concurs with this recommendation as the preferred
alternative.
IV. ESTIMATED COSTS
The estimated costs for the build alternative is as follows:
Item Cost
Structure $ 280,000
Roadway Approaches 416,000 ,
Structure Removal 18,000
Misc. & Mob. 249,000
Eng. & Contingencies 162,000
Total Construction Cost 1,125,000
Right-of-way Costs 198,000
Total Project Cost $ 1,323,100
V. NATURAL RESOURCES
A. Physical Resources
Water Resources
Alarka Creek is not the only surface water resource located within the project study area. A
small unnamed tributary converges into Alarka Creek approximately 400 feet west of the
existing bridge. Alarka creek and the unnamed tributary are located in sub-basin 04-04-02 of the
Little Tennessee River Basin. The average baseflow widths for Alarka Creek and the unnamed
tributary are approximately 24 feet and 2.5 feet respectively. The average depth of Alarka Creek
is approximately 2 feet. The small-unnamed tributary's depth is approximately 2 inches. The
substrate of both Alarka Creek and its tributary are mostly cobbles and silt.
Streams have been assigned a best usage classification by the North Carolina Division of Water
Quality. The classification of Alarka Creek and the unnamed tributary is C Tr. Class C refers to
waters suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation,
and agriculture. The supplemental classification of Tr denotes Trout Waters that require
protection for natural trout propagation and survival of stocked trout.
Neither High Quality Waters (HQW), Water Supplies (WS-I: undeveloped watersheds or WS-II:
predominately undeveloped watersheds) nor Outstanding Resource Waters (ORW) occur within
1.0 miles of the project study area.
Biotic Resources
Four distinct terrestrial communities are identified in the project study area: Rich Cove Forest,
riparian, maintained yard, and maintained/disturbed roadside. Two distinct aquatic communities
are identified in the project study area: Alarka Creek and unnamed tributary. Community
boundaries within the study area are well defined without significant transition zone between
them. Faunal species likely to occur within the study area will exploit all six communities for
shelter and foraging opportunities or as movement corridors.
Table 1. Anticipated Impacts
COMMUNITY AQUATIC UPLAND
Rich Cove Forest - 2.44 acres
Riparian - 0.60 acres
Maintained Yard - 0.34 acres
Maintained/Disturbed - 0.92 acres
Alarka Creek 0.71 acres -
Unnamed Tributary 0.00 acres -

B. Jurisdictional Topics
Alarka Creek is a jurisdictional surface water under Section 404 of the Clean Water Act.
Discussion of the biological, physical, and water quality aspects of all surface waters in the
roject area arc-presentcd in-previous-sections-of-this--report.
Summary of Anticipated Impacts
Anticipated impacts to surface waters are determined by using the entire project study area of
5.44 acres. With this assumption, the impacts to Alarka Creek and its small-unnamed tributary
would total an area of 0.71 acres.
Permits
Nationwide Permit 23 (33 CFR 330.5(a) (23)) is likely to be applicable for all impacts to "Waters
of the United States" resulting from the proposed project. This permit authorizes activities
undertaken, assisted, authorized, regulated, funded, or financed in whole or part by another
federal agency or department where that agency or department has determined that pursuant to
the Council on Environmental Quality regulation for implementing the procedural provisions of
the National Environmental Policy Act.
This project will also require a 401 Water Quality Certification from the DWQ prior to the
issuance of the Nationwide Permit. Section 401 of the Clean Water Act requires that the state
issue or deny water certification for any federally permitted or licensed activity that may result in
a discharge to "Waters of the United States." Section 401 Certification allows surface waters to
be temporarily impacted for the duration of the construction or other land manipulation. The
issuance of a 401 permit from the DWQ is a prerequisite to issuance of a Section 404 permit.
A North Carolina Division of Water Quality (DWQ) Section 401 Water Quality General
Certification is required prior to the issuance of the Section 404 Individual Permit. Since the
proposed project is located in a designated "Trout" county, the authorization of a nationwide
permit by the COE is conditioned upon the concurrence of the Wildlife Resources Commission
(WRC)•
The proposed project is located in the Tennessee Valley Authority's (TVA) Land Management
District. A permit pursuant to Section 26a of the TVA Act, is required for all construction or
development involving streams or floodplains in the Tennessee River drainage basin.
Federally-Protected Species
Plants and animals with federal classifications of Endangered (E), Threatened (T), Proposed
Endangered (PE), and Proposed Threatened (PT) are protected under the provisions of Section 7
and Section 9 of the Endangered Species Act of 1973, as amended. As of February 25, 2003, the
U.S. Fish & Wildlife Service lists ten federally protected species for Swain County (Table 2).
Table 2. Federally Protected Species for Swain County.

Glaucomys sabrinus coloratus Carolina Northern Flying Squirrel Endangered ,
Felis concolor couguar Eastern cougar Endangered
Wothc sadalis 1??din Endangered
Cyprinella monacha Spotfin chub Threatened
Alasmindonta raveneliana Appalachian elktoe Threatened
Pegias fibula Little-wing pearly mussel Endangered
Patera clarki nantahala Noonday globe Threatened
Microhexura montivaga Spruce-fir moss spider Endangered
Spiraea virginiana Virginia spirea Threatened
Gymnoderma lineane Rock gnome lichen Endangered
CAROLINA NORTHERN FLYING SQUIRREL ENDANGERED
The elevation of 1,840 feet within the project study area does not meet the habitat requirements.
A review of the NC Natural Heritage Program database of rare species and unique habitats on
May 15, 2001 revealed no record of the presence of northern flying squirrel within the project
vicinity. Project construction will not effect the northern flying squirrel.
BIOLOGICAL CONCLUSION: NO EFFECT
EASTERN COUGAR ENDANGERED
No evidence of the eastern cougar was observed during site investigations. However, it is
possible that the eastern cougar could exist in or near the project study region. It is improbable
that the bridge replacement will have any substantial impacts to the eastern cougar's habitat or
forage if it did exist in the project region. A review of the NC Natural Heritage Program database
of rare species and unique habitats on May 15, 2001 revealed no record of the presence of
Eastern Cougar within the project vicinity.
BIOLOGICAL CONCLUSION: NO EFFECT

INDIANA BAT ENDANGERED
BHE Environmental Inc. of Cincinnati, Ohio conducted a survey in July 2002. No Indiana bats
were capture during the survey. Based on the surveys, the Indiana at does not appear to utilize
the project areas for maternity roosting. Project construction will potentially destroy suitable
spring/summer roosting habitat for Indiana bats. However, the destruction of habitat is
considered insignificant because the US Forest Service currently has greater than 500,000 acres
of suitable spring/summer roosting habitat that would be utilized by Indiana bats under
protection. In addition, the forest management plan implemented on US Forest Service land is
converting multiple acres of unsuitable forest into suitable spring/summer roosting habitat for the
Indiana bat annually. Potentially, individual Indiana bats could use the project area for foraging
and/or temporary roosting. Any impacts to the foraging or temporary roosting habitat within the
project corridor is not expected to adversely impact this species.
BIOLOGICAL CONCLUSION: NOT LIKELY TO ADVERSELY AFFECT
SPOTFIN CHUB THREATENED
Habitat for the Spotfin chub exists within the project area. A survey conducted in the year 2000
found no presence of the chub. The survey is currently in need of update. Given that the likely
outcome of the project will be NOT LIKELY TO ADVERSELY AFFECT, the FHWA and
USFWS have agreed to allow the CE to be completed with the commitment that the survey will
be updated during the 2004 survey season.
BIOLOGICAL CONCLUSION: UNRESOLVED

APPALACHIAN ELKTOE ENDANGERED
Suitable habitat does exist within the project study area. A review of the NC Natural Heritage
Program database of rare species and unique habitats, on May 15, 2001, revealed no record of the
presence of Appalachian elktoe within the project vicinity. On April 24, 2001, NCDOT
Environmental Specialists Tim Savidge and Logan Williams conducted surveys within the
project study area. No live mussels were found during the survey. It was concluded, based on
historic distribution of these species and the habitat present in Alarka Creek, that there is a
remote possibility that this mussel may occur in Alarka Creek downstream of the project area.
BIOLOGICAL CONCLUSION: NOT LIKELY TO ADVERSELY AFFECT
7

LITTLE WING PEARLY MUSSEL ENDANGERED
Suitable habitat does exist within the project study area. A review of the NC Natural Heritage
Program-data , 2001, -revealed no record o he
presence of Little wing pearly mussel within the project vicinity. On April 24, 2001, NCDOT
Environmental Specialists Tim Savidge and Logan Williams conducted surveys within the
project study area. No live mussels were found during the survey. It was concluded, based on
historic distribution of these species and the habitat present in Alarka Creek, that there is a
remote possibility that this mussel may occur in Alarka Creek downstream of the project area. .
BIOLOGICAL CONCLUSION: NOT LIKELY TO ADVERSELY AFFECT

NOONDAY GLOBE THREATENED
Suitable habitat in the form of rocky slopes and wet ravines are not present within the project
study area. The noonday globe is believed only to occur within a two-mile stretch of the
Nantahala Gorge on north-facing cliffs. A review of the NC Natural Heritage Program database
of rare species and unique habitats on May 15, 2001 revealed no record of presence of noonday
globe within the project vicinity.
BIOLOGICAL CONCLUSION: NO EFFECT

SPRUCE-FIR MOSS SPIDER ENDANGERED
The elevation of 1,840 feet within the project study area does not meet the habitat requirements
for the spruce-fir moss spider. A review of the NC Natural Heritage Program database of rare
species and unique habitats on May 15, 2001 revealed no record of the presence of spruce-fir
moss spider within the project vicinity.
BIOLOGICAL CONCLUSION: NO EFFECT

8

VIRGINIA SPIREA THREATENED
Suitable habitat in the form of scoured banks, meander scrolls, point bars, natural levees, or
na ura eri ge
does exist vvithin the project study area. A review of NC -
ui aiu
Program database of rare species and unique habitats, on May 15, 2001 revealed no record of the
presence of Virginia spirea within the project vicinity. No spirea specimens were observed.
BIOLOGICAL CONCLUSION: NOT LIKELY TO ADVERSELY AFFECT

ROCK GNOME LICHEN ENDANGERED
Suitable habitat in the form of vertical rock faces with seepage does not exist within the project
study area. A review of the NC Natural Heritage Program database of rare species and unique
habitats on May 15, 2001 revealed no record of the presence of rock gnome lichen within the
project vicinity.
BIOLOGICAL CONCLUSION: NO EFFECT
Because of the duration of the project planning process, some of the original T&E surveys need
to be updated. NCDOT has coordinated with the FHWA.and USFWS and determined that we
can move forward with the signing of the Categorical Exclusion with a commitment to update
the surveys and follow through with all necessary coordination prior to project construction.
VI. CULTURAL RESOURCES
A. Compliance Guidelines
This project is subject to compliance with Section 106 of the National Historic Preservation Act
of 1966, as amended, implemented by the Advisory Council on Historic Preservation's
Regulations for Compliance with Section 106, codified at Title 36 CFR Part 800. Section 106
requires Federal agencies to take into account the effect of their undertakings (federally funded,
licensed, or permitted) on properties included in or eligible for inclusion in the National Register
of Historic Places and afford the Advisory Council a reasonable opportunity to comment on such
undertakings.
B. Historic Architecture
The North Carolina Department of Cultural Resources has reviewed this project and determined
that there are no structures of historic significance that could be affected by the project. An
attached concurrence form dated March 18, 2003 indicates that no structures of historical
significance will be affected by this project.
9
C. Archaeology
In a letter dated November 2, 2000 (see attached letter), the NCDCR recommended an
archaeological survey be conducted if a new alignment was proposed. In a subsequent review of
maps provided, NCDCR modified their original recommendation in a letter dated October 25,
2002 (see attached letter). The letter indicates that there are no likely archaeological resources of
historic significance that could be affected by the project. No archaeological work is
recommended for this location.
VII. GENERAL ENVIRONMENTAL EFFECTS
The project is expected to have an overall positive impact. Replacement of an inadequate bridge
will result in safer traffic operations.
The project is considered to be a Federal "Categorical Exclusion" due to its limited scope and
lack of substantial environmental consequences.
The bridge replacement will not have an adverse effect on the quality of the human or natural
environment with the use of the current North Carolina Department of Transportation standards
and specifications.
The project is not in conflict with any plan, existing land use, or zoning regulation. No change in
land use is expected to result from the construction of the project.
No adverse impact on families or communities is anticipated. Right-of-Way acquisition will be
limited. No relocatees are expected with implementation of the proposed alternative although one
house 250 feet east of the bridge, and currently unoccupied will be taken by the proposed
alignment. In addition, there is one small-dilapidated abandoned building to the west of the
bridge along the south side of the road that will be taken by the project.
No adverse effect on public facilities or services is expected. The project is not expected to
adversely affect social, economic, or religious opportunities in the area.
The proposed project will not require right-of-way acquisition or easement from any land
protected under Section 4(f) of the Department of Transportation Act of 1966.
The Farmland Protection Policy Act requires all federal agencies or their representatives to
consider the potential impact to prime farmland of all land acquisition and construction projects.
There are no soils classified as prime, unique, or having state or local importance in the vicinity
of the project.
10
This project is an air quality "neutral" project, so it is not required to be included in the regional
emissions analysis and a project level CO analysis is not required. If vegetation is disposed of by
burning, all burning shall be done in accordance with applicable local laws and regulations of the
North Carolina State Implementation Plan (SIP) for air quality in compliance with 15 NCAC
?D 0520
Noise levels could increase during construction but will be temporary. This evaluation completes
the assessment requirements for highway traffic noise of Title 23, Code of Federal Regulation
(CFR), Part 772 and for air quality (1990 Clean Air Act Amendments and the National
Environmental Policy Act) and no additional reports are required.
An examination of records at the North Carolina Department of Environment and Natural
Resources, Division of Environmental Management, Groundwater Section and the North
Carolina Department of Human Resources, Solid Waste Management Section revealed no
underground storage tanks or hazardous waste sites in the project area.
Swain County is a participant in the National Flood Insurance Program. There are no practical
alternatives to crossing the floodplain area. Any shift in alignment will result in an impact area of
about the same magnitude. The proposed project is not anticipated to increase the level or extent
of upstream flood potential.
On the basis of the above discussion, it is concluded that no substantial adverse environmental
impacts will result from implementation of the project.
VII. OTHER PROJECT COORDINATION
As illustrated in Figure 2, the footprint of the project impacts a slope that nears The Great
Smokey Mountain Railroad. The railroad bed itself will not be impacted but the footprint shown
is currently forested and would be cleared of trees exposing a rock slope. Preliminary
coordination has occurred with an official from The Great Smokey Mountain Railroad who has
raised concerns over the impacts to the viewshed. The Final Design and Right of Way phases
are the appropriate time frames to pursue the types of information and negotiation required to
resolve this issue.
The Wildlife Resource Commission has identified Alarka Creek as a Hatchery Supported trout
stream also containing wild trout populations in the area. Their primary concerns were that the
replacement structure be a spanning structure and that a construction moratorium from
November 1 through April 15 be observed to protect the egg and fry stages of trout development.
Other general requirements outlined in their attached letter have been included in the attached
Project Commitments Sheet.
Because of the duration of the project planning process, some of the original T&E surveys need
to be updated. NCDOT has coordinated with the FHWA and USFWS and determined that we
can move forward with the signing of the Categorical Exclusion with a commitment to update
the surveys and follow through with all necessary coordination prior to project construction.

Re: Replacement of Bridge No. 106 over Alarka Creek on SR 1309. TIP No. B-3701. Swain
County, ER 00-8459
Dear Mr. Graf.
On May 7. 2000, April Montgomery met with North Carolina Department of Transportation
(NCDOT) staff for a meeting of the minds concerning the above project. We reported our
available information on historic architectural and archaeological surveys and resources along
with our recommendations. NCDOT provided project area photographs at the meeting.
Based upon a review of the photographs and the information discussed at the meeting. we offer
our preliminary comments regarding this project.
In terms of historic architectural resources, we are aware of no structures located within the area
of potential effect. However, since the project area has not been surveyed in over a decade, there
be structures of architectural or historical significance of which we are unaware. We recommend
an architectural historic on your staff identify and evaluate any properties over fifty years of age
within the project area and report the findings to us.
There are no recorded archaeological sites within the proposed project area. If the replacement is
to be located along the existing alignment, it is unlikely that significant archaeological resources
would be affected and no investigations would be recommended. If, however, the replacement is
to be in a new location, please forward a map to this office indicating the location of the new
alignment so we may evaluate the potential effects of the replacement upon archaeological
resources.
The above comments are made pursuant to Section 106 of the National Historic Preservation Act
and the Advisory Council on Historic Preservation's Regulations for Compliance with Section
106 codified at 36 CFR Part 800.

MEMORANDUM
TO: John L. Williams, Bridge Planning Unit
Project Development and Environmental Analysis Branch, NCDOT

FROM: Mark S. Davis, Mountain Region Coordinator
Habitat Conservation Program l,?l??(?/.l
DATE: May 16, 2000
SUBJECT: Scoping comments on Bridge Replacement Projects
TIP Project No. B-3635 over Junaluska Creek, Cherokee County
TIP Project No. B-3701 over Alarka Creek, Swain County
This memorandum responds to your request for our concerns regarding impacts on fish and
wildlife resources resulting from the subject projects. The North Carolina Wildlife Resources Commission
(NCWRC) has reviewed the proposed projects, and our comments are provided in accordance with
provisions of the National Environmental Policy Act (42 U.S.C. 4332(2)(c)) and the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d).
The proposed work involves 2 bridge replacement/demolition projects in western North Carolina
(listed below). Construction impacts on wildlife and fisheries resources will depend on the extent of
disturbance in the streambed and surrounding floodplain areas. We prefer bridge designs that do not alter
the natural stream morphology or impede fish passage. Bridge designs should also include provisions for
the deck drainage to flow through a vegetated upland buffer prior to reaching the subject surface waters.
Demolition plans for the existing bridge structures should be addressed in the environmental documents
prepared for these projects, as well as any proposed causeways, temporary access roads or detours. We
are also concerned about impacts to Designated Public Mountain Trout Waters (DPMTW) and
environmental docuruentation for these projects should include a description of any streams or wetlands on
the project site and surveys for any threatened or endangered species that may be affected by construction.
B-3635 - Cherokee County, Bridge No. 26 on SR 1505 over Junaluska Creek
Junaluska Creek is managed by the NCWRC as Hatchery Supported trout water and also supports
wild trout populations in the project area. The project scoping sheet indicates that the bridge will
be replaced with a 3 (rJl 10' x 5' RCBC just upstream of the existing bridge. Due to the presence
of trout in the project area, we recommend that the existing bridge be replaced with another
spanning structure. We also recommend that instream work be prohibited during the trout
spawning period of November I through April 15 to protect the cgg and fry stages from off situ
sedimentation.

B-3701 - Swain County, Bridge No. 106 on SR 1309 over Alarka Creek
Alarka Creek is managed by the NCWRC as Hatchery Supported trout water and also supports
wild trout populations in the project area. We recommend that the existing bridge be replaced Nvith
another spanning structure. We also recommend that instream Nvork be prohibited during the trout
spawning period of November 1 through April 15 to protect the egg and fry stages from off-site
sedimentation.
Because the Corps of Engineers (COE) recognizes the above counties as "trout water counties",
the NCWRC will review any nationwide or general 404 permits for the proposed projects. The following
conditions are likely to be placed on the subject 404 permits:
Adequate sedimentation and erosion control measures must be implemented prior to any
ground disturbing activities to minimize impacts to downstream aquatic resources. Structures
should be inspected and maintained regularly, especially follo«ing rainfall events.
2. Temporary or permanent herbaceous vegetation should be planted on all bare soil within 15
days of ground disturbing activities to provide long-term erosion control.
3. All work in or adjacent to stream waters should be conducted in a dry work area. Sandbags,
rock berms, cofferdams, or other diversion structures should be used where possible to prevent
excavation in flowing water.
4. If concrete is used during construction, a dry work area must be maintained to prevent direct
contact between curing concrete and stream water. Uncured concrete affects water quality and
is highly toxic to fish and other aquatic organisms.
5. Grading and backfilling should be minimized, and tree and shrub growth should be retained if
possible to ensure long term availability of shoreline cover for gamefish and wildlife.
6. Instream construction is prohibited during the trout spawning period of November 1 to
April 15 to avoid impacts on trout reproduction.
7. Heavy equipment should be operated from the bank rather than in stream channels in order to
minimize sedimentation and reduce the likelihood of introducing other pollutants into streams.
8. If multi-celled reinforced concrete box culverts are utilized, they should be designed so that all
water flows through a single cell (or two if necessary) during low flow conditions. This could
be accomplished by constructing a low sill on the upstream end of the other cells that will
divert low flows to another cell. This will facilitate fish passage at low flows.
9. Notched baffles should be placed in reinforced concrete box culverts at 15 foot intervals to
allow for the collection of sediments in the culvert, reduce flow velocities, and to provide
resting places for fish moving through the structure.
10. Only clean, sediment-free rock should be used as temporary fill (causeways), and should be
removed without excessive disturbance of the natural stream bottom when construction is
completed.
