NC 194, Bridge No. 45 over
Bairds Creek, Watauga County,
State Project No. 8.1751201
Federal-Aid Project BRS-1451(6)
I. D. No. B-2178
Bridge No. 45 has been included in the Federal-Aid Bridge Replacement
Program. The location is shown in Figure 1. No substantial environmental
impacts are anticipated. The project has been classified as a Federal
"categorical exclusion."
I. SUMMARY OF ENVIRONMENTAL COMMITMENTS
All standard procedures and measures will be implemented to avoid or
minimize environmental impacts. No special or unique environmental
commitments are necessary. A nationwide permit is likely to be
applicable. Concurrence from NCWRC is needed since the project is in one
of the 25 trout counties. A 401 water quality permit will be required.
There are no jurisdictional wetland plant communities located in the study
area. Best management practices will be utilized to minimize these
impacts. Consideration will be given to a bottomless culvert during the
permitting and design phase.
II. SUMMARY OF RECOMMENDATIONS
Bridge No. 45 should be replaced at the existing location with a
cast-in-place reinforced culvert as shown by Alternative 1 (Figure 2).
Only minimum approach work is required to tie the culvert to existing
approaches.
Preliminary hydrographic studies indicate that a triple 9' x 7' box
culvert should be provided.
Traffic will be maintained on-site by a temporary detour structure
located immediately west of the existing structure.
Estimated cost, based on current prices, is $ 395,000 which includes
$ 95,000 for the right-of-way costs.
The estimated cost of the project, as shown in the Transportation
Improvement Program, is $ 290,000.
III. EXISTING CONDITIONS
NC 194 is classified as a rural major collector in the Statewide
Functional Classification System and is part of the Federal Aid System
(FAS 1451). NC 194 is also considered to be a North Carolina Scenic
Byway. The North Carolina Scenic Byways Program brings attention to the
beautiful countryside and historic areas in North Carolina. The route
runs through Banner Elk and Boone and serves the outlying rural area north
of Valle Crucis.
2

In the vicinity of the bridge, NC 194 has a 16-foot pavement with
3-foot shoulders (see Figure 2). Vertical alignment is flat. The
horizontal alignment consists of curves on both approaches in excess of 29
degrees. The structure is situated 9 feet above the creek bed. Posted
speed limit is 55 MPH. Land use in the immediate vicinity of the bridge
is woodland. Development in the surrounding area is residential.
The current traffic volume of 1200 vehicles per day (vpd) is expected
to increase to approximately 2000 vpd by the year 2011. The projected
volume includes 1% truck-tractor semi-trailer (TTST) and 3% dual-tired
vehicles (DT).
The existing bridge (see Figure 3) was constructed in 1959. The
superstructure consists of a timber deck with I- beams on rubble masonry
abutments. The substructure is composed of rubble masonry caps.
Overall length is 25 feet. Clear roadway width is 19.2 feet. The
posted weight limit is 20 tons for single vehicles and 29 tons for trucks
with trailers.
Bridge No. 45 has a sufficiency rating of 34.2 compared to a rating
of 100 for a new structure.
Two accidents were reported on Bridge No. 45 during the period from
July 1, 1987 to June 30, 1991. Both accidents occurred at the
intersection of NC 194 and SR 1117.
Six school buses cross the studied bridge daily.
IV. ALTERNATIVES
Two alternative methods of replacing Bridge No. 45 were studied as
follows:
Alternative 1 (Recommended) will involve replacement of the bridge
along t He existing roadway alignment with a cast-in-place reinforced
concrete box culvert (3 @ 9' x 7'). Traffic will be maintained on-site
with a temporary detour structure (two @ 72" corrugated metal pipes)
located immediately west of the existing structure. Environmental impacts
as a result of constructing Alternative 1 are less than under
Alternative 2.
Alternative 2 would involve replacement of the bridge with a culvert
on new location dust west of the existing structure. The replacement
structure would be a cast-in-place box culvert (3 @ 9'x7'). Traffic would
be maintained on the existing structure during construction. Alternative
2 would result in a greater loss of plant species.
"Rehabilitation" of the old bridge is not feasible due to its age and
deteriorated condition.
The "do-nothing" alternative would eventually necessitate closure of
the bridge. This is not desirable due to the traffic service provided by
NC 194.
3
V. ESTIMATED COST
Estimated cost of the studied alternatives is as follows:

(Recommended)
Alternative 1 Alternative 2
Structure & Approaches $ 255,000 $ 337,000
Structure Removal $ 4,000 $ 4,000
Temporary Detour $ 16,000 _
Engineering & $ 25,000 $ 34,000
Contingencies
Right-of-Way, Utilities $ 95,000 $ 71,000
Total $ 395,000 $ 446,000
VI. TRAFFIC DETOUR
During the construction period, maintenance of traffic at the studied
bridge site is necessary. Otherwise, traffic would have to be detoured
along existing unpaved secondary roads with poor vertical and horizontal
alignment and over bridges with poor sufficiency ratings. No acceptable
detour route was found due to the excessive length of additional travel.
In view of these existing factors, it is clear that traffic should be
maintained at the existing site during construction.
VII. RECOMMENDED IMPROVEMENTS
Bridge No. 45 should be replaced at its present location with a
cast-in-place reinforced concrete box culvert. According to the
preliminary hydrographic study, a triple 9' x 7' reinforced concrete box
culvert will accommodate the flow of Bairds Creek at this point. The
structure dimensions may be increased or decreased as necessary to
accommodate peak flows of Bairds Creek as determined by further
hydrographic studies.
Alternative 1 is the recommended alternative because construction
costs and environmental impacts will be lower as compared to Alternative
2. Alternative 1 (Recommended) has a higher design speed than Alternative
2. Also, the sight distance problem for motorists looking north along
NC 194 from SR 1117 (Mast Gap Road) will be improved more easily under
Alternative 1. Therefore, it is recommended to improve the subject
project as outlined under Alternative 1.
The recommended improvements will include about 100 feet of improved
roadway approaches. A 22-foot pavement with 6-foot graded shoulders
should be provided on the approaches. The elevation of the new crossing is
expected to be approximately the same as the elevation of the existing
bridge.

VIII. ENVIRONMENTAL IMPACTS
The project is located north of Valle Crucis in Watauga County in the
Mountain Physiographic Province. The project is located in a rural
setting. Several homes are near the project site. The study area is
forested and disturbed.
Topography in the area ranges from gently to strongly sloping.
Elevation ranges from 2660' to 2700' above mean sea level (amsl).
Topography in the study area is gently sloping adjacent to Bairds Creek
and strongly sloping northwest of the bridge/creek crossing.
A disturbed scrub/shrub upland community is located adjacent to the
creek at the existing bridge and to the west of the bridge. This
community is open and supports few trees. Weedy grasses and shrubs
predominate adjacent to the creek. Observed plants include blackberry
(Rubus sp.), smooth sumac (Rhus gla?bra), various composites and grasses.
Several trees, including tuT p poplar (Liriodendron ttuulipifeera) and
northern red oak ( uercus rubra), are located along the stream banks. A
maintained lawn exists to tFesouth and west of the bridge. The hillside
located between the road and the hardwood forest community is disturbed
and is also dominated by blackberry.
A hardwood forest upland community is located immediately west and
north of the bridge. The area is strongly sloping and the elevation
increases from the roadway to the hardwood forest community. The ground
is very rocky. Several exposed boulders are located uphill of the study
area. The dominant canopy species are deciduous hardwood trees. A number
of oaks such as northern red oak, white oak ( uercus alba) and southern
red oak (uercus falcata) are found in this community. Additional tree
species include Pignut ?iickory (Cater a_ gla?bra), red maple (Acer rubrum) and
cherry birch (Betula lenta). The un ed rstory is dominateT_5y_Fa`w`t_F6rn
(Cratae uuss sp.). Due to seasonality, the ground cover was not observable
at the time of the field survey. Remnants of last seasons' growth include
squaw-root (Conopholis americana).
No wetland plant communities are located in the study area. Only
Waters of the US will be impacted by the proposed project.
Construction will impact Disturbed Scrub/Shrub and the Hardwood
Forest communities. Plant community impacts are presented in Table 1.
These estimates are preliminary and may change with final design.

0.4 0.4
Note: Estimated impacts are based on 60' right-of-way width. Values shown
are in acres.

The project impacts a disturbed area. A small amount of the Hardwood
Forest community will be impacted from proposed construction. Potential
impacts include vegetation loss and regrowth of species adapted to a
disturbed environment.
Construction of either alternative will result in similar vegetation
losses, but construction of Alternative 1 (Recommended) will result in a
temporary vegetation loss since proposed construction consists of
replacement on existing location and construction of a temporary detour.
Construction of Alternative 2 consists of permanent vegetation losses
since construction is proposed on new location. The existing facility
would be removed and re-vegetated.
It is recommended that stringent erosion control measures and Best
Management Practices should be enforced during the life of the project.
Sedimentation Control guidelines should be implemented. It is also
recommended that vegetation removal should be minimized. The existing
facility (Alternative 2) should be graded to normal elevations and
re-established with native vegetation.
The following avian species may be found in the study area:
red-tailed hawk (Buteo 'amaicensis), American kestrel (Falco s arverius),
mourning dove (Ze a as macroura , red-headed woodpecker Me aner es
er throce halus), raven Corvus corax), cedar waxwing (Bom yci a
ce rorum an American goldTln--c (Cardu-61is tristis).
Anticipated amphibians and reptiles in the study area include: seal
salamander (Desmo nathus monticola), mountain dusky salamander
(Desmo nathus oc ro aeus), t ree- fined salamander (Eur cea uttolineata),
re acc salamander Pet odon cinereus), slimy salaman er Pet o don
lutinosus), southern re ack salamander (Plethodon serratus , mud
salamander (Pseudotriton montanus), spring peeper H crucifer), green
frog (Rana c-lamitans ; eastern fence lizard (Sceloporusun -u itus),
five -li e3 s in Eumeces fasciatus), southeastern five- fine Mink
(Eumeces inexpectatus ringnecke (Diado his uncta?tus), queen snake
( Jna septemvittata) and eastern ribbon -snake Thamnophis sauritus).
Several mammals may inhabit the study area. They include the water
shrew (Sorex alustris), least shrew (Cr totis ppar..__v.a), star-nosed mole
(Cond Tura cristata , eastern cotton tai Sy ?i?agus floridanus),
woodchuck (Marmota monax), pine vole (Microtus pinetorum) an the raccoon
(Procyon lotor .
Recent fisheries information is not available for Bairds Creek
according to NCWRC. The potential exists for rainbow trout (Oncorh ncus
mykiss) and brook trout (Salvelinus fontinalis) since these species have
been found in nearby streams.
Bairds Creek is listed in a 1968 publication (Fish) as a small stream
with limited fishing importance. Anticipated fish species in Bairds Creek
include suckers (Catastomus spp.), warmouth (Lepomis ug losus) and rock
bass (Ambloplites rupestris .
6
Replacement of the bridge with a culvert might hinder normal fish
movement and stream dynamics may be altered. The proposed culvert will
divide the stream into three separate channels and may form a barrier to
the migration of certain aquatic species. Construction at Bairds Creek
may increase siltation and sedimentation to the creek. These potential
impacts may reduce the number of sensitive species, including filter
feeders and nonmobile organisms in Bairds Creek.
Construction of Alternative 1 (Recommended) is more desirable than
construction of Alternative 2 since Alternative 1 impacts are temporary.
The temporary detour or permanent roadway (new location) will impact an
area with strong slopes. Construction in this area may increase erosion
and siltation. Installation of a culvert designed with no floor slab or a
bridge that spans the entire stream width would limit the impacts to the
creek. One of these designs should be considered during the design and
permitting phase. If a conventional culvert is used for bridge
replacement then it should be placed at least 12 inches below the stream
bottom (for fish movement). A low flow notch will be cut into one cell of
a multi-celled concrete box culvert, and deflectors will direct water into
this cell during low flows. If pipes are used for temporary detour
construction, then they should be placed on grade with the stream bottom
in order to minimize the impacts on the stream. Placement of a culvert
with no floor slab that spans the entire creek would reduce impacts as
compared to a standard multi-celled culvert. Stringent erosion control
measures and Best Management Practices (BMP) will be enforced during the
life of the project. Sedimentation Control guidelines will be
implemented. The temporary detour piping and approach fills will be
removed and the area returned to natural conditions after construction is
completed.
Soils information was obtained from the local Soil Conservation
Service office in Watauga County. Soils information is provided from a
survey completed in December, 1991. Watauga County is currently being
surveyed to update soil information.
Two soil mapping units are located in the study area. Cullowhee
fine-sandy loam and Chestnut-Ashe complex. The majority of the creek
floodplain is mapped Cullowhee fine-sandy loam. This mapping unit is
found on 0-3 percent slopes and is occasionally flooded. This soil is
somewhat poorly drained and has grey mottles in the 12" to 24" layer of
the profile. This soil is classified as having hydric inclusions.
The Chestnut-Ashe complex is located in areas with slopes ranging
from 50 to 95 percent such as the hardwood forest and is very rocky. The
Chesnut-Ashe complex is classified as a non-hydric soil.
The project is located in the Watauga River Basin. Bairds Creek is a
tributary of the Watauga River. The creek is approximately 20' wide in
the study area, has a depth of approximately 1' and is fast flowing. The
bottom composition varies from boulders to cobble and silt. Best usage
classification of Bairds Creek is C (DEM). Best usage recommendations for
Class C waters include aquatic propagation and survival, fishing,
wildlife, secondary recreation and agriculture.
7
No High Quality Waters, Outstanding Resource Waters or waters
classified WS-I and WS-II are located in the study area or within 1 mile
downstream. Bairds Creek is not designated a Public Mountain Trout Water
• by the North Carolina Wildlife Resources Commission (NCWRC).
Benthic macroinvertebrate surveys were taken in the Watauga River
less than 5 miles downstream of the study area. The bioclass was rated
from good to,excellent. The bioclass is a measure of the taxa richness
and the presence of intolerable organisms. Ratings in Watauga River have
oscillated in earlier sampling years, but have recently stabilized within
the excellent category. Benthic macroinvertebrates are sensitive to very
subtle changes in water quality.
Non-point sediment sources will be identified and efforts made to
control sediment runoff. Strict adherence to BMP's will be followed
during the construction phase of the project. Sedimentation Control
guidelines will be implemented prior to construction and maintained
throughout the life of the project. The culvert should be placed at least
12 inches below the stream bottom (for fish movement). A low flow notch
should be cut into one cell of a multi-celled concrete box culvert, and
deflectors should direct water into this cell during low flows. If pipes
are used for temporary detour construction, then they should be placed on
grade with the stream bottom in order to minimize the impacts to the
stream.
Jurisdictional wetlands as defined by 33 CFR 328.3 are those areas
that are inundated or saturated by surface or ground water at a frequency
and duration sufficient to support, and that under normal circumstances do
support, a prevalence of vegetation typically adapted to life in saturated
conditions. Criteria for wetland determinations are described in the
"Corps of Engineers Wetland Delineation Manual" (Environmental Laboratory,
1987). Any action that proposes to place fill into these areas falls
under the jurisdiction of the US Army Corps of Engineers under the
Provisions of the Clean Water Act.
Impacts in the study area fall under the broad phrase "Waters of the
US". Waters of the US includes, in general terms, navigable waters, their
tributaries and associated wetlands. The bank-to-bank surface waters of
Bairds Creek fall under this category. There are no jurisdictional
wetland plant communities located in the study area.
The proposed project will impact the surface waters of Bairds Creek.
No jurisdictional wetland plant communities are located in the study area.
Bairds Creek is not a designated trout water. A Nationwide Permit 33 CFR
330.5(a) (23) is likely to be applicable. Nationwide Permit 23 approves
activities undertaken, assisted, authorized, regulated, funded in whole or
in part by another federal agency where that agency or department has
determined, pursuant to the Council on Environmental Quality Regulation
for Implementing the Procedural Provisions of the National Environmental
Policy Act, that the activity, work or discharge is categorically excluded
from environmental documentation because it is included in a category of
actions which neither individually nor cumulatively has a significant
effect on the environment.
8
The project is located in one of the 25 trout counties. Concurrence
from the NCWRC is required for projects that occur in these counties.
Correspondence with NCWRC has been initiated (see Appendix, A-3).
State permits are administered through the Department of Environment,
Health and Natural Resources (DEHNR). One state permit that is required
s is the 401 Water Quality Certification. This certificate is issued for
any activity which may result in a discharge and for which a federal
permit is required.
The US Fish and Wildlife Service (USFWS) and the North Carolina
Natural Heritage Program (NCNHP) were consulted to locate any occurrences
of protected species in the study area.
Six federally protected species are listed by the USFWS for Watauga
County as of January 30, 1992. These are as follows:
Common Name Scientific Name
Virginia big-eared bat Plecotus townsendii v??ir99inianus
Carolina northern flying squirrel G a?ucom s sabrinu coloratus
Spreading avens Geum radiatum
Mountain bluet Houstonia montana
Heller's blazing star Lia-` tris - Fiel -Fe r Blue ridge goldenrod Solidago spi Famaea
Virginia big-eared bat
The Virginia big-eared bat is distinguished by its very large ears,
usually 1" or longer. This medium sized bat has brownish fur and is
approximately 4" long. The species is widespread in the western United
States, but the eastern subspecies is fragmented into several populations.
It inhabits caves only. Hibernation sites average 12° C or less. No
caves are located in the study area. No impacts to the Virginia big-eared
bat will occur.
Carolina northern flying squirrel
The Carolina northern flying squirrel is a small nocturnal mammal
approximately 12" long. It is capable of gliding by means of a membrane
that is located along the sides of the body between the fore and hind
limbs. In addition, the broad tail aids in gliding. The Carolina
northern flying squirrel is distributed in widely scattered areas at high
elevations in the transition zone between the coniferous and northern
hardwood forests. The study area does not occur at high elevations nor
does it support suitable habitat for the Carolina northern flying
squirrel. No impacts will occur.
Spreading avens
This perennial herbaceous plant is a member of the rose family. The
flowers are bright yellow and the flowering period is from June through
August. It is endemic to balds on high mountains and often occurs on
steep mountain faces and narrow ledges. The study area does not support
suitable habitat for this plant. No impacts to spreading avens will
occur.
9
Mountain bluet
This perennial herb has a basal rosette of leaves. The flowers are a
• bright yellow and the flowering period is from June through September.
The Mountain Bluet inhabits areas similar to the spreading avens, high
elevation rock cliffs. The study area does not support suitable habitat
for this plant. No impacts to the plant will occur.
Heller's blazing star
Heller's blazing star is a member of the aster family. Flowers occur
in clusters and are rarely solitary, blooming late July through August
from the top to the bottom of the stem. Flowers are lavender to pink or
white. The plant occurs on drier mountaintop cliff edges, in shallow
acidic soils, usually on weathered granite above 3500' in elevation. The
study area does not support suitable habitat for this plant. No impacts
to Heller's blazing star will occur.
Blue-ridge goldenrod
The blue-ridge goldenrod is an erect perennial herb that arises from
a stout rhizome. The yellow flowers are borne in heads and the flowering
period is July through August. Three populations are known; two in Avery
County and one in Mitchell County. The blue-ridge goldenrod occurs at
elevations above 4600' in dry rock crevices of granite outcrops on the
high peaks of the Blue Ridge Mountains. The study area occurs well below
4600' and does not support suitable habitat for this plant. No impacts
will occur to the blue ridge goldenrod.
No records of state protected species are located in the study area
according to the NCNHP files.
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 36 CFR Part 800. It is also subject to
compliance with Section 4(f) of the Department of Transportation Act of
1966, as amended.
In terms of historic architectural resources, there are no National
Register-listed or eligible properties located in the area of potential
effect.
There are no known archaeological sites within the proposed project
area. Based on our present knowledge of the area, it is unlikely that any
archaeological resources which may be eligible for inclusion in the
National Register of Historic Places will be affected by the project
construction. There are no publicly owned parks, historic sites,
recreational facilities, or wildlife and waterfowl refuges of national,
state or local significance in the vicinity of the project. Therefore,
the project does not involve any Section 4(f) properties.
10
A
Since there are no properties either listed or eligible for listing
in the National Register of Historic Places in the area of potential
effect of this undertaking, no further compliance with either Section 106
of the National Historic Preservation Act of 1966 or with Section 4(f) of
the Department of Transportation Act of 1966 is required (see Appendix
pages A-1 and A-2).
The project is not in conflict with any plan, existing land use, or
zoning regulation. No significant change in land use is expected to
result from construction of the project.
The structure is to be replaced at the existing location. Therefore,
the project is exempt from the Farmland Protection Policy Act.
Watauga County is a participant in the National Flood Insurance
Regular Program. The area of drainage basin for Bairds Creek at the
subject location is 3.35 square miles. The approximate 100-year flood
plain in the project area is shown in Figure 4. The amount of flood plain
area to be affected is not considered to be significant.
The project is located within the Eastern Mountain Air Quality
Control Region. The ambient air quality for Watauga County has been
determined to be in compliance with the National Ambient Air Quality
Standards. Since this project is located in an area where the State
Implementation Plan (SIP) does not contain any transportation control
measures, the conformity procedures of Title 23, Code of Federal
Regulations (CFR), Part 770 do not apply to this project.
The project will not substantially increase traffic volumes.
Therefore, its impact on noise levels and air quality will be
insignificant. Noise levels could increase during construction but will
be temporary. If vegetation is disposed of by burning, all burning shall
be done in accordance with applicable local laws and regulations of the
North Carolina SIP for air quality in compliance with 15 NCAC 2D.0520.
This evaluation completes the assessment requirements of Title 23, Code of
Federal Regulations (CFR), Part 770 and 772 and no additional reports are
required.
