SUBJECT: Information for the proposed replacement of Bridge Nos.
49 and 50 over Middle Fork and East Fork on on SR 1522
(Deerfield Road) in Watauga County, Division 11. Federal
Project No. MABRSTP-1522(2), State Project No. 8.2750801,
T.I.P. No. B-3066.
Dear Madam:
Please find enclosed three copies of the CE document and roadway design plan sheet for
the above referenced project. This project involves the replacement of Bridge Nos.
49 and 50 on slightly new alignments to facilitate improvements to the current S-curve
alignment. Two perennial streams Middle Fork [DWQ Index No. 10-1-2-(15)] and
East Fork [DWQ Index No. 10-1-3-(8)] with classifications of WS-IV CA+ exist within
the project area. No surface waters or jurisdictional wetlands will be impacted as a result
of the proposed project. Therefore, no permit drawings are attached. Best Management
Practices for Bridge Demolition and Removal will be followed when removing Bridge
Nos. 49 and 50. Therefore, no debris will be dropped into Waters of the United States.
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 March 077, 2002,
the United States Fish and Wildlife Service lists six federally protected species for
Watauga County: bog turtle, Carolina northern flying squirrel, spruce-fir moss spider,
spreading avens, Roan Mountain bluet, and Heller's blazing star. The bog turtle is listed
as Proposed Threatened due to similarity of appearance to other rare species that are
listed for protection. This species is not biologically endangered or threatened and is not
subject to Section 7 consultation. Therefore, no biological conclusion is required. The
Biological Conclusions of "No Effect" for the other five species remain valid.

SUMMARY
This project will take place in a mountain trout county. Thus we anticipate that
comments from the North Carolina Wildlife Resources Commission (NCWRC) will be
required. NCWRC specifically requested to review the final design plans, prior to
construction. By copy of this letter and attachment, NCDOT hereby requests NCWRC
review and that NCWRC forward their comments to the Corps of Engineers.
Proposed project activities are being processed by the Federal Highway Administration
as a programmatic "Categorical Exclusion" in accordance with 23 CFR § 771.115(b). No
permit is being requested because no jurisdictional Waters of the United States will be
impacted. However, we are providing two copies of this application to the North
Carolina Department of Environment and Natural Resources, Division of Water Quality,
for their records.
Thank you for your assistance with this project. If you have any questions or need
additional information please call Ms. Heather Montague at [phone].

SUBJECT: Review of Categorical Exclusion for the proposed replacement of Bridge Nos. 49
& 50 over Middle Fork and East Fork on SR 1522 (Deerfield Road) in Watauga
County. TIP No. B-3066.
North Carolina Department of Transportation (NCDOT) has submitted a Categorical
Exclusion document to the U.S. Army Corps of Engineers (USACE). Staff biologists with the
North Carolina Wildlife Resources Commission (NCWRC) have reviewed the document. These
comments are provided in accordance with the 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 NCDOT proposes to replace Bridge Nos. 49 and 50, in Boone, NC, on slightly new
alignment to facilitate improvements to the current S-curve alignment (Preferred Alternative No.
3). The bridges cross East Fork and Middle Fork in the New River drainage. Both streams are
classified as WS-IV CA+ and support wild trout populations. A raw water intake for the City of
Boone is located approximately 1,400 feet downstream of Bridge No. 49. The Kanawha minnow
(Phenacobius teretulus), Federal Species of Concern and state listed as Special Concern, and the
Kanawha darter (Etheostonta kanawhae), state listed as Significantly Rare, have been observed
in the project area. No surface waters or jurisdictional wetlands will be directly impacted by this
project.
The project impacts approximately 0.22 acres of maintained open area of the Lee and
Vivian Reynolds Greenway. The Town of Boone has suggested that a pedestrian walkway be
added to the north side of SR 1522 to allow easier and safer access by local citizens. We have no
objection to this, but would like to encourage NCDOT to consider using non-impervious

materials to construct sidewalks, particularly in developed watersheds with a high percentage of
impervious surfaces. This would be especially appropriate in a greenway setting.
NCWRC supports the plans to replace the bridges with spanning structures, use "Design
Standards in Sensitive Watersheds" and restrict any in-stream work and land disturbance in the
25-foot buffer from October 15 to April 15. In addition, we recommend the following conditions
be implemented:
Stringent sedimentation and erosion control measures must be implemented and
maintained on the project site until project completion to avoid impacts to downstream
aquatic resources. Temporary or permanent herbaceous vegetation should be planted on
all bare soil within 10 days of ground disturbing activities to provide long-term erosion
control. Fescue should not be permitted. Erosion control matting should be used in
riparian areas, instead of straw mulch and well anchored with 12" staples or 12" wooden
survey stakes.
2. Removal of vegetation in riparian areas should be minimized. Native trees and shrubs
should be planted along the stream banks to reestablish the riparian zone and to provide
long-term erosion control.
3. 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 fish and
wildlife. Backfill materials should be obtained from upland sites.
4. Riprap should be minimized and installed in a manner so as not to interfere with aquatic
life passage during low flow conditions. Riprap placed for bank stabilization should be
limited to the stream bank below the high water mark, and vegetation should be used for
stabilization above the high water elevation.
Under no circumstances should rock, sand, or other materials be dredged from the stream
channel, except in the immediate vicinity of bridge supports, if applicable.
6. Discharge of materials into the stream from demolition of old bridges should be avoided
as much as practicable. Any materials that inadvertently reach the stream should be
removed.
7. Stormwater, including deck drainage, should be routed to buffer areas and not discharged
directly to the stream.
8. If concrete will be used during construction, work must be accomplished so that wet
(uncured) concrete does not contact surface waters. This will lessen the chance of
altering the water chemistry and causing a fish kill.
9. Discharging hydroseeding mixtures and washing out hydroseeders and other equipment
in or adjacent to surface waters is strictly prohibited.

February 14, 2003
10. Heavy equipment should be operated from the bank rather than in the stream channel
whenever possible in order to minimize sedimentation and reduce the likelihood of
introducing other pollutants into the stream. All mechanized equipment operated near
surface waters should be inspected and maintained regularly to prevent contamination of
stream waters from fuels, lubricants, hydraulic fluids or other toxic materials.
Thank you for the opportunity review and comment on this project. If you have any
questions regarding these comments, please contact me at [phone].

T.I.P. No. B-3066
INTRODUCTION: Bridge Nos. 49 and 50 are included in the 2002-2008 North Carolina Department of
Transportation (NCDOT) Transportation Improvement Program (TIP) and in the Federal Aid Bridge
Replacement Program. The location of these bridges is shown on 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 indicated the bridges were last inspected in September 1999.
The results of the inspection indicate Bridge No. 49 has a sufficiency rating of 36.9 and Bridge No. 50 has
a sufficiency rating of 25.2, out of a possible 100 for a new structure. Both bridges are considered
"functionally obsolete". The replacement of these inadequate structures will result in safer and more
efficient traffic operations.
II. EXISTING CONDITIONS
The project is located in the central part of Watauga County within the jurisdictional limits of the
Town of Boone. The immediate area is largely suburban in nature, transitioning into an urban area
dominated by commercial and professional businesses on the western end of the project. Watauga
Medical Center lies just southwest of the project study area. Boone Golf Club, a public 18-hole course,
lies to the south side of the project and is within the project study area. The east end of the project leads
to a suburban area dominated by modem residential developments. This area was recently annexed into
the Town of Boone and is the fastest growing suburban area in the county.
According to NCDOT Statewide Planning Branch, SR 1522 (Deerfield Road) is classified as an
urban collector route in the Statewide Functional Classification System. Per communication received
from NCDOT, Division of Bicycle and Pedestrian Transportation, this route is not a designated bicycle
route and there is no indication that an unusual number of bicyclists utilize this roadway (See letter in
Appendix).
2
In the vicinity of the bridges, SR 1522 is a 20-foot (6.0-meter) paved, 2-lane roadway with 4-foot
(1.2-meter) grass shoulders. The roadway grade is relatively flat through the project area. Bridge No. 49
is located on a short tangent between reverse curves and Bridge No. 50 is located on a horizontal curve.
The roadway is situated approximately 7 feet (2.1 meters) above the riverbed at Bridge No. 49 and 6 feet
(1.8 meters) at Bridge No. 50.
i
The current (2000) traffic volume of 11,200 vehicles per day (VPD) is expected to increase to
20,500 VPD by the year 2025. The project volume includes 1- percent truck-tractor semi-trailer (TTST)
and 2- percent dual-tired vehicles (DT). The posted speed limit in the project area is 35 mph (56.3 km/h).
There were 7 accidents reported in the vicinity of Bridge Nos. 49 and 50 during the 3-year period
beginning September 01, 1993 through August 31, 1996. These figures resulted in an annual accident
rate of 72.61 ACC/100 MVM.
Bridge No. 49 is a 44.25 feet (13.5 meters) long single span structure with a clear roadway width
of 28 feet (8.4 meters) (See Figure 3a). The bridge has an asphalt wearing surface on a steel plank floor
supported by twelve lines of 21-inch (53.3-centimeter) steel I-beams. The end bents consist of timber
caps with timber posts and concrete sills. The paint system is aluminum paint over red lead paint. The
posted weight limit on this bridge is 31 tons (28.1 metric tons) for single vehicles and 34 tons (30.8 metric
tons) for tractor trailer/semi-trucks. The existing bridge was constructed in 1956 and is in fair condition.
Bridge No. 50 is a 30.5 feet (9.3 meters) long single span structure with a clear width of 28.17
feet (8.6 meters) (See Figure 3b). The bridge has an asphalt wearing surface on a steel plank floor
supported by twelve lines of 16-inch (40.6 centimeters) steel I-beams. The end bents consist of timber
caps with timber posts and concrete sills. The paint system is aluminum paint over red lead paint. The
posted weight limit on this bridge is 19 tons (17.2 metric tons) for single vehicles and 24 tons (21.8 metric
tons) for tractor trailer/semi-trucks. The existing bridge was constructed in 1959 and is in fair condition.
There are no utilities attached to either structure; however, power and telephone lines are located
overhead to the south side of SR 1522 and underground sewer, water and fiber optic lines run along the
north side of SR 1522. Overall, utility impacts are anticipated to be low and any specific impacts will be
coordinated with appropriate utility personnel during construction.
3
Four school buses cross these bridges eight times daily on their routes. In a letter dated February
15, 2000, the Watauga County Board of Education indicated that closing these bridges during school
operating hours would cause considerable hardship in routing buses and would significantly increase the
bus ride time for students living in the area; however, with enough advance warning the buses could be
re-routed (See letter in Appendix).
III. ALTERNATIVES
A. Project Description
The replacement structures will consist of the following:
Bridge No. 49 - The replacement structure for Bridge No. 49 over Middle Fork will consist of a
one-span bridge, 65 feet (19.8 meters) long and 40 feet (12.4 meters) wide. The replacement
structure will require spill-through abutments at each end. This structure will provide two 12-foot
(3.6-meter) lanes with 8-foot (2.4-meter) shoulders on each side (See Figure 4).
Bridge No. 50 - The replacement structure for Bridge No. 50 over East Fork will consist of a one-
span bridge, 55 feet (16.8 meters) long and 40 feet (12.4 meters) wide. The replacement structure
will require spill-through abutments at each end. This structure will provide two 12-foot (3.6-
meter) lanes with 8-foot (2.4-meter) shoulders on each side (See Figure 4).
The recommended bridge lengths are based on a preliminary hydraulic analysis. The final design
of the bridge will be such that the backwater elevation will not encroach beyond the current 100-year
floodplain limits. The lengths of the new structures may be increased or decreased as necessary to
accommodate peak flow as determined by further hydrologic studies.
The roadway grades of the new structures will be approximately the same as the existing grades
at these same locations.
The proposed approach roadway will consist of a 24-foot (7.3 meters) pavement width to provide
two 12-foot (3.6-meter) lanes with 8-foot (2.4-meter) shoulders including 4-foot (1.2-meter) full-depth
paved shoulders on each side in accordance with current NCDOT policy (See Figure 4).

B. Reasonable and Feasible Alternatives
The alternatives studied for replacing Bridge Nos. 49 and 50 are shown on Figure 2 and described
below:
Alternative 1 - replaces both bridges on the existing alignment (Figure 2). The approach work
will extend from approximately 320 feet (97.6 meters) west of Bridge No. 49 to approximately
210 feet (64.0 meters) east of Bridge No. 50 for a total length of approximately 1,090 feet (332.2
meters). The design speed is 40 mph (64.4 km/h). A design exception will be necessary for the
horizontal alignment near both bridges. An off-site detour will be used to maintain traffic during
the construction period. The length of the off-site detour is approximately 3.8 miles (6.1
kilometers). This alternative is not recommended due to the high traffic volumes using the
existing roadway and the inadequate detour route available.
Alternative 2 - replaces Bridge No. 49 approximately 80 feet (24.4 meters) downstream (north)
of the existing structure and Bridge No. 50 approximately 60 feet (18.3 meters) downstream
(north) of the existing structure (Figure 2). The existing bridges will be used to maintain traffic
on-site during construction. The new alignment will have a design speed of 40 mph (64.4 km/h)
and will be approximately 1,050 feet (320.1 meters) in length. A design exception will be
necessary for the horizontal alignment at Bridge No. 50. This alternative is not recommended
because of the potential impacts to the "Blair House" property which is considered eligible for
listing on the National Register of Historic Places (See letter in Appendix).
Alternative 3 (Preferred) - replaces Bridge No. 49 approximately 75 feet (22.9 meters)
downstream (north) of the existing structure and Bridge No. 50 approximately 65 feet (19.8
meters) upstream (south) of the existing structure (Figure 2). The existing bridges will be used to
maintain traffic on-site during construction. The new alignment will have a design speed of 40
mph (64.4 km/h) and will be approximately 1,185 feet (361.2 meters) in length. A design
exception will not be necessary for this alternative.
C. Alternatives Eliminated from Further Study
An alternative that provides an on-site detour route was considered. This alternative was
eliminated due to the impacts to the adjacent properties, the additional project cost, the project duration
and the substandard alignment of the existing roadway.
5
A box culvert was not considered a feasible alternative for this location.
The No Build or "Do Nothing" alternative will eventually necessitate closure of these bridges.
This is not acceptable due to the traffic service provided by SR 1522.
"Rehabilitation" of the existing structures is not feasible due to their age and deteriorated
condition.
D. Preferred Alternative
Bridge Nos. 49 and 50 will be replaced on new location as shown by Alternative 3 in Figure 2.
Alternative 3 is recommended because it maintains traffic on-site during construction, improves the
existing roadway alignment and avoids the historic "Blair House" property.
The NCDOT Division 11 Engineer concurs with Alternative 3 as the Preferred Alternative.
IV. ESTIMATED COSTS
The estimated costs, based on current prices (2000), are as follows:
Table 1.0 Estimated Costs per Alternative
Alternative 1 Alternative 2 Alternative 3
(Preferred)
Structure $312,000 $416,000 $444,000

V. NATURAL RESOURCES
A. Methodology
The information contained in this section is based on the Natural Sysfems Report (July 2000)
prepared by Environmental Services Inc., appended by reference.
The project study area was visited, walked and surveyed for significant features in January 2000.
The project study area encompasses the various alternatives under consideration and is approximately
1,200 feet (365.8 meters) in length and ranges between 200 and 300 feet (61.0 and 91.5 meters) in width.
Impact calculations for each alignment are based on a right-of-way width of approximately 100 feet (30.5
meters) for each alignment. Actual impacts will be limited to construction limits and will be less than
those shown for right-of-way. Special concerns evaluated in the field include potential habitat for
protected species, streams, wetlands, and water quality protection.
Plant community descriptions are based on a classification system utilized by the North Carolina
Natural Heritage Program (NHP) (Schafale and Weakley 1990). When appropriate, community
classifications were modified to better reflect field observations. Vascular plant names follow
nomenclature found in Radford et al. (1968). Jurisdictional areas were identified using the three
parameter approach (hydrophytic vegetation, hydric soils, wetland hydrology) following U.S. Army
Corps of Engineers (COE) delineation guidelines (DOA 1987). Jurisdictional areas were characterized
according to a classification scheme established by Cowardin et al. (1979). Habitat used by terrestrial
wildlife and aquatic organisms, as well as expected population distributions, were determined through
field observations, evaluation of available habitat, and supportive documentation (Martof et al. 1980,
Webster et al. 1985, Menhinick 1991, Hamel 1992, Rohde et al. 1994). Water quality information for
area streams and tributaries was derived from available sources (DEM 1989, DEM 1993, DEM 1994,
DENR 1999). Quantitative sampling was not undertaken to support existing data.
The most current FWS listing of federally protected species with ranges that extend into Watauga
County was obtained prior to initiation of the field investigation (list date June 16, 2000). In addition,
NHP records documenting presence of federal or state listed species were consulted before commencing
the field investigation (review date January 10, 2000).
7
B. Physiography and Soils
The project study area is located in the Mountain physiographic province. Topography in this
province is generally characterized by strongly sloping to very steep uplands with narrow floodplains
along drainages; however, elevations in the project study area range from approximately 3,120 feet (951
meters) above mean sea level (MSL) at the eastern end of the project study area, to approximately 3,100
- feet (945 meters) above MSL along the channel of Middle Fork (USGS Boone, NC quadrangle).
The project study area crosses four soil mapping units: Chestnut-Edneyville Complex, 30-60%
slopes, stony (Typic Dystrochrepts, Typic Dystrochrepts); Edneytown loam, 15-30% slopes (Typic
Hapludults); Rosman fine sandy loam, occasionally flooded (Fluventic Haplumbrepts); and Urban Lands,
flooded. These mapping units are all well drained non-hydric soils.
C. Water Resources
I. Waters Impacted
The project study area is located within sub-basin 050701 of the New River Basin (DEM 1994).
This area is part of USGS accounting unit 0505001 (USGS 1974). Bridge No. 49 crosses Middle Fork
approximately 600 feet (183 meters) southwest of the intersection of SR 1522 and SR 1592. Middle
Fork, from 0.4- mile (0.6-kilometer) downstream of US 221/321 through the project study area to the
South Fork New River, has been assigned Stream Index Number (SIN) 10-1-2-(15) by the N.C. Division
of Water Quality (DWQ). Middle Fork flows from south to north within the project study area and joins
East Fork to form the South Fork New River approximately 700 feet (213 meters) downstream from
existing Bridge No. 49.
Bridge No 50 crosses East Fork approximately 150 feet (45.7 m) southwest of the intersection of
SR 1522 and SR 1592. East Fork, from 0.8-mile (1.3-kilometer) downstream of SR 1524 through the
project study area to the South Fork New River, has been assigned SIN 10-1-3-(8). East Fork flows from
south to north within the project study area and joins Middle Fork to form the South Fork New River
approximately 400 feet (122 meters) downstream from existing Bridge No. 50.

a. Stream Characteristics
Middle Fork is a perennial stream with moderate flow over substrate consisting of sand, gravel,
cobble and boulders. A geomorphic characterization of the stream section within the project study area
indicates Middle Fork is a "B" channel (Rosgen 1996). This designation indicates a stream that exists on
moderately steep to gently sloped terrain with a predominant landform of a narrow and moderately
sloping basin. The "B" stream type exhibits low sinuosity and is rapids dominated with relatively deep
scour pools. Middle Fork is a rapids-dominated, single channel stream with a bankfull width of
approximately 25 feet (7.6 meters) at existing Bridge No. 49, which narrows to approximately 18 feet
(5.5 meters) downstream from the bridge and then widens to approximately 25 feet (7.6 meters) at the
northern (downstream) project study area boundary. The bankfull width of the channel narrows to
approximately 8 feet (2.4 meters) immediately upstream of the bridge and then widens to approximately
20 feet (6.1 meters) at the southern (upstream) study project area boundary. Pool depths at bankfull stage
within the channel range from 1 to 2.5 feet (0.3 to 0.76 meters). No rooted aquatic vegetation was
apparent in the channel, but some organic debris (i.e., branches, leaves) was apparent.
East Fork is a perennial stream with slow flow over substrate consisting of sand, gravel, and
cobble. A geomorphic characterization of the stream section within the project study area indicates the
segment of East Fork within the project study area contains three stream types. From the upstream study
area boundary to Bridge No. 50 East Fork is an "F" channel with a bankfull width of approximately 18
feet (5.5 meters). From Bridge No. 50 to a point approximately 50 feet (15.2 meters) downstream of the
bridge East Fork is a "B" channel with a bankfull width of approximately 12 feet (3.7 meters). From a
point approximately 50 feet (15.2 meters) downstream from the bridge to the downstream project study
area boundary East Fork is a "C" channel with a bankfull width of approximately 35 feet (10.7 meters).
The "F" designation indicates a deeply incised, relatively wide and shallow, meandering channel
in gentle terrain. The segment of East Fork south of Bridge No. 50 is located within Boone Golf Club.
The channel has a bankfull width of approximately 18 feet (5.5 meters). The 4-foot (1.2-meter) deep
channel has been straightened and the sides of the channel have been lined with riprap.
The "B" designation indicates a stream which exists on moderately steep to gently sloped terrain
with a predominant landform of a narrow and moderately sloping basin. The "B" stream type exhibits
low sinuosity and is "rapids" dominated with relatively deep scour pools. This segment of East Fork
exhibits a rapids dominated channel with slight meanders and pool depths of approximately 2 feet (0.6
meters).
9
The "C" designation indicates a relatively wide, meandering channel with a shallow water depth,
within deeply incised banks with a functional floodplain. This segment of East Fork has a functional
floodplain and well formed meanders, riffles, and pools. Pool depth within the stream sections average
approximately 2.5 feet (0.76 meters).
b. Best Usage Classifications and Water Quality
Classifications are assigned to waters of the State of North Carolina based on the existing or
contemplated best usage of various streams or segments of streams in the basin. Middle Fork, from a
point 0.4-mile (0.6-kilometer) downstream of US 221/321 through the project study area to the South
Fork New River, has a best usage classification of WS-IV CA + (DEM 1993, DENR 1999). The WS-IV
designation indicates waters which are protected as water supplies in moderately to highly developed
watersheds. Point source discharges of treated wastewater are permitted in these waters, pursuant to
Rules .0104 and .0211 of 15A NCAC 2B; however local programs to control nonpoint source and
stormwater discharge of pollution are required. These waters also support aquatic life propagation and
survival, fishing, wildlife, secondary recreation, and agriculture. Secondary recreation is any activity
involving human body contact with water on an infrequent or incidental basis. The CA indicates a
"Critical Area", which is defined as the land areas within 0.5-mile (0.8-kilometer) upstream and draining
to water supplies from the normal pool elevation or 0.5-mile (0.8-kilometer) and draining to a
river/stream intake. Protection rules applying to the "Critical Area" are more stringent than those in the
remainder of the watershed. The symbol "+" indicates waters that are subject to a special management
strategy specified in 15A NCAC 2B .0225, the Outstanding Resource Waters (ORW) Rules, in order to
protect downstream waters designated ORW, which are considered unique and special waters of
exceptional state or national recreational or ecological significance which require special protection to
maintain existing uses.
East Fork, from a point 0.8-mile (1.3-kilometer) downstream of SR 1522 through the project
study area to the South Fork New River, also has a best usage classification of WS-IV CA +.
No Outstanding Resource Waters (ORW), WS I, or WS-II Waters occur within 3.0 miles (4.8
kilometer) upstream or downstream of Bridge Nos. 49 and 50. Neither Middle Fork nor East Fork is
designated as a North Carolina Natural and Scenic River, nor as a national Wild and Scenic River.
10
Neither Middle Fork nor East Fork are Designated as Public Mountain Trout Water (DPMTW),
which includes publicly accessible waters managed for stocked and wild trout by the North Carolina
Wildlife Resources Commission (WRC); however, these streams are known to contain wild trout.
There is one permitted point source discharger on Middle Fork, the Blowing Rock Waste Water
Treatment Plant (NPDES NC0027286/001), located approximately 5.0 miles (8 kilometers) upstream of
the project study area. This plant has a permitted discharge of 0.8 million gallons per day (MGD) (DEM
1994). There is one permitted discharger located approximately 2.0 miles (3.2 kilometers) downstream
from the project study area on the South Fork New River, the Boone Waste Water Treatment Plant
(NPDES NC0020621), which has a permitted discharge of 3.2 MGD (DEM 1994).
During one field visit, a raw water intake for the City of Boone was identified downstream from
the project study area on the South Fork New River, approximately 1,400 feet (426.7 meter) downstream
from Bridge No. 49.
Two potential point source dischargers were noted on Middle Fork within the project study area.
The first potential discharger occurs immediately south of Bridge No. 49 and east of Middle Fork on the
golf course. This potential discharger consists of a grassy swale which connects the golf course to Middle
Fork. The second potential discharger occurs approximately 130 feet (39.6 meters) north of Bridge No.
49 and west of Middle Fork. This potential discharger consists of a pipe entering Middle Fork from the
west. No flow was noted from either potential discharger at the time of the field work.
There are no permitted point source dischargers on East Fork (DEM 1989, DEM 1994). No point
source dischargers were noted as occurring on East Fork within the project study area.
A benthic macroinvertebrate monitoring station is present on Middle Fork within the project
study area at Bridge No. 49. This station received a bioclassification of Excellent in 1993 (DEM 1994).
A benthic monitoring station is present on East Fork at Bridge No. 50. This station received a
bioclassification of Excellent in 1993 (DEM 1994).
An additional monitoring station is located on the US 221/421 bridge over the South Fork New
River, approximately 2.6 miles (4.2 km) downstream from the project study area, below the outfall from
11
the Boone Waste Water Treatment Plant. This station received a bioclassification of Good-Fair in 1988
(DEM 1989) and Fair in 1993 (DEM 1994).
Another measure of water quality being used by the DWQ is the North Carolina Index of Biotic
Integrity (NCIBI), which assesses biological integrity using the structure and health of the fish
community; however, no fish community structure sampling has been reported for the New River Basin
(DEM 1994).
2. Anticipated Impacts to Water Resources
Section 402-2 of NCDOT's Standard Specifications for Roads and Structures is labeled Removal
of Existing Structure. This section outlines restrictions and Best Management Practices for Bridge
Demolition and Removal (BMP-BDRs), as well as guidelines for calculating maximum potential fill in
the stream channel resulting from demolition. Waters within the project study area have a best usage
classification of WS-1V CA +, which are protected under the ORW rules. The proposed project is a Case
1 stream crossing according to BMP-BDRs. Case 1 stream crossings limit in-water work to an absolute
minimum, except for the removal of the portion of the sub-structure below the water. All work must be
carefully coordinated with the responsible agency to protect the special resource water.
With the exception of structures which are constructed of all steel/timber, all spans over the
channel are considered potential fill. The superstructures of both Bridge No. 49 and Bridge No. 50 are
steel planks on I-beams and the substructures are timber end bents. Neither Bridge No. 49 nor Bridge No.
50 contain any reinforced concrete, negating the need to include the spans as potential fill impacts into
their respective waters. The superstructures and substructures are slated for removal in such a manner
that no bridge components are dropped into the stream channels.
After construction activities are completed, abandoned existing approaches associated with
Alternative 2 and Alternative 3 will be removed and revegetated in accordance with current NCDOT
guidelines.
Short-term impacts to water quality, such as sedimentation and turbidity, can be anticipated from
construction-related activities. BMPs can minimize impacts during construction, including
implementation of stringent erosion and sedimentation control measures, and avoidance of using wetlands
as staging areas.
12
Other impacts to water quality that may occur as a result of this project include: changes in water
temperature as a result of increased exposure to sunlight, increased shade due to the construction of the
bridges, and changes in stormwater flows due to changes in the amount of impervious surface adjacent to
the stream channels. However, due to the limited amount of overall change in the surrounding areas,
impacts are expected to be temporary in nature.
WRC has prohibited any in-stream work and land disturbance activities within 25 feet (7.6
meters) of Middle Fork and East Fork associated with this project during the trout spawning season of
October 15 through March 31 (See letter dated August 23, 1999 contained in Appendix and personal
communication with J. Mickey, January 10, 2000).
No adverse long-term impacts to water resources are expected to result from any of the
alternatives being considered. Alternative 1 includes replacement of the existing structures with channel-
spanning structures; Middle Fork has a bankfull width of approximately 25 feet (7.6 meters) at Bridge
No. 49, East Fork has a bankfull width of approximately 18 feet (5.5 meters) at Bridge No. 50. The
complete bridging of these channels will negate any in-stream impacts and will allow for continuation of
present stream flow in both Middle Fork and East Fork, thereby protecting stream integrity.
Alternative 2 includes channel-spanning structures which cross Middle Fork approximately 80
feet downstream of Bridge No. 49 and cross East Fork approximately 60 feet (18.3 meters) downstream
of Bridge No. 50. Middle Fork has a bankfull width of approximately 20 feet (6.1 meters) at the proposed
crossing; East Fork has a bankfull width of approximately 15 feet (4.6 meters) at the proposed crossing.
Traffic will be maintained on the existing structures during construction. Complete bridging of both
channels will negate any in-stream impacts and will allow for continuation of present stream flow in both
Middle Fork and East Fork, thereby protecting stream integr ity. The existing bridges and approaches will
be removed after construction of Alternative 2. The areas will be revegetated following the removal of
the existing structures and approaches.
Alternative 3 includes channel-spanning structures which cross Middle Fork approximately 75
feet (22.9 meters) downstream of Bridge No. 49 and cross East Fork approximately 65 feet (19.8 meters)
upstream of Bridge No. 50. Middle Fork has a bankfull width of approximately 20 feet (6.1 meters) at the
proposed crossing; East Fork has a bankfull width of approximately 18 feet (5.5 meters) at the proposed
crossing. Traffic will be maintained on the existing structures during construction. Complete bridging of
both channels will negate any in-stream impacts and will allow for continuation of present stream flow in
13
both Middle Fork and East Fork, thereby protecting stream integrity. The existing bridges and
approaches will be removed after construction of Alternative 3. The areas will be revegetated following
the removal of the existing structures and approaches.
BMP's to be followed for this project are outlined in "Design Standards in Sensitive Watersheds"
(NCAC 04B .0024), and will be adhered to during design and construction of this project in and around
all waters classified as WS, ORW, HQW, or Tr. This includes all waters within the project study area.
D. Biotic Resources
1. Plant Communities
Two plant communities were identified within the project study area: rocky bar and
maintained/disturbed areas. These communities are described below:
Rocky Bar - The rocky bar community is associated with Middle Fork in two areas. The first area is
immediately downstream of Bridge No. 49, on the western bank. The second area is approximately 50
feet (15.2 m) upstream of Bridge No. 49, on the eastern bank. Although rocky bar is considered a natural
plant community, the rocky bar communities within the project study area receive regular impacts from
anthropogenic causes, including limited clearing. The first area is adjacent to a small parking area
associated with the Reynolds Greenway; the second area is adjacent to the Boone Golf Club. These areas
are small and consist of vegetated bars composed of sand, gravel and cobble. They are vegetated with
plume grass (Andropogon virginicus), blackberry (Rubus spp.), and scattered saplings of black willow
(Saliz nigra), red maple (Ater rubrum) and black locust (Robinia pseudoacacia).
Alaintained/Disturbed Areas - The majority of the project study area is composed of
Maintained/Disturbed areas. Vegetation within this community varies across the project study area.
Boone Golf Club lies southeast of SR 1522 from Middle Fork to the eastern project study area
boundary. East Fork flows through the golf course. This area consists of a paved golf cart path and
bridge and maintained fairways with scattered white pine (Phw strobus), black walnut (Juglans nigra),
and scattered patches of rosebay (Rhododendron maximum).
Residential yards, businesses, and a farm field lie northwest of SR 1522; a residential yard lies
southeast of SR 1522, west of Middle Fork. Vegetation in these areas consist of maintained yards with
14
scattered white pine, sugar maple (Ater sacchanim) and red maple, with scattered clumps of wild rose
(Rosa sp.) and asters (Aster spp.).
Roadside margins contain varied species, including saplings of sweet birch (Betula lenta), black
locust, and scarlet oak (Quercus coccinea), with rosebay, wild rose, and greenbrier (Smilax sp.).
Vegetation associated with stream banks include scattered mature individuals of black locust,
sweet birch, and white pine, with scattered rosebay, black willow, plume grass, blackberry, various asters,
greenbrier, and goldenrod (Solidago sp.).
2. Anticipated Impacts to Plant Communities
No undisturbed natural plant communities are located within the project study area. Anticipated
impacts to plant communities are estimated based on the acreage of each plant community present within
the proposed right-of-way of 100 feet (30.5 meters); actual impacts within construction limits will be less.
Alternative 1 potential impacts include the right-of-way area adjacent to both bridges. Alternative 2 and
Alternative 3 include potential impacts outside their respective 100-feet (30.5 meters) rights-of-way
associated with demolition of the existing structures. A summary of potential plant community impacts is
presented below:

Total: 0.35 (0.14) 1.75 (0.71) 1.61 (0.65)
15
Permanent impacts to plant communities as a result of bridge replacement are generally limited to
narrow strips adjacent at the existing bridge structure and roadway approach segments; temporary impacts
due to bridge demolition have been included in the above table but not in the alternative analysis.
Fragmentation of natural communities will not occur as a direct result of this project due to the lack of
natural plant communities within the project study area.
Alternative 1 is the second shortest alternative, approximately 1,090 feet (332.2 meters) total, and
has the least amount of potential plant community impact, 0.35 acres (0.14 hectares). Alternative 2 is the
shortest alternative of approximately 950 feet (290 meters) but has the largest amount of permanent
impacts to 1.67 acres (0.68 hectares) due to a relatively lesser amount of roadway and other impervious
surfaces within the proposed right-of way. Alternative 3 is the longest alternative of approximately 1,185
feet (361.2 meters) and has the second largest permanent impact to 1.51 acres (0.61 hectares). Although
Alternative 3 is approximately 135 feet (41.2 meters) longer than Alternative 2, potential plant
community impact for Alternative 3 is 0.16 acres (0.06 hectares) less than Alternative 2 due to a greater
amount of road surface and other impervious surfaces present in Alternative 3.
3. Wildlife
The study project area was visually surveyed for signs of terrestrial and aquatic wildlife.
Although little evidence of wildlife was observed during the field effort, expected wildlife species are
those adapted to suburban areas.
a. Terrestrial
No bird species were observed within or adjacent to the project study area. Bird species expected
within and around the project study area include American crow (Corvus brachyrhynchos), Carolina
chickadee (Poecile carolinensis), northern cardinal (Cardinalis cardinalis), tufted titmouse (Baeolophus
bicolor), dark-eyed junco (Junco hyemalis), mourning dove (Zenaida macroura) and blue jay (Cyanocitta
cristata).
Mammal sign (tracks, scat, etc.) observed within the project study area includes raccoon (Procyon
lotor) and beaver (Castor canadensis). Other species expected include woodchuck (Marmota monax),
Virginia opossum (Didelphis virginiana), gray squirrel (Sciurus carolinensis) and eastern cottontail
(Sylvilagu s Jloridanus).
16
Due to the season in which the fieldwork was conducted, no terrestrial reptiles were observed
within the project study area. Expected reptiles include eastern garter snake (Thamnophis sirtalis), black
rat snake (Elaphe obsoleta), and eastern box turtle (Terrapene carolina).
No terrestrial amphibians were observed within the project study corridor. Species expected to
occur within the project study area include red-spotted newt (Notophthabnus viridescens) and American
toad (Bufo americanus).
b. Aquatic
Limited kick-netting, seining, dip-netting, and visual observation of stream banks and channel
within the project study area were conducted in Middle Fork and East Fork.
Fish species documented in the segment of Middle Fork within the project study area include
fantail darter (Etheostoma flabellore) and mottled sculpin (Cottus bairdi). The varied riverine habitat and
good water quality is expected to support numerous other species. Potential nongame fish which may be
present include central stoneroller (Campostoma anomalum), white sucker (Catostomus commersoni),
warpaint shiner (Luxilus coccogenis), rosy side dace (Clinostomus funduloides) and New River shiner
(Notropis scabriceps). Potential game fish which may be present include rainbow trout (Onocorhyncus
mykiss), brown trout (Salmo trutta), brook trout (Salvelinus fontinalis), smallmouth bass (Microterus
dobnieu), and rock bass (Ambloplites rupestris) (Menhinick 1991, Rohde et al. 1994). There are no
anadromous fish within this system.
Fish species documented within the segment of East Fork within the project study area include
central stoneroller, mottled sculpin, and New River shiner. The varied riverine habitat and good water
quality is expected to support a fish population similar to that expected for Middle Fork (Menhinick 1991,
Rohde et al. 1994).
Aquatic invertebrate surveys consisted of walking all streambanks in the project study area to
locate freshwater mussel middens and conducting limited in-stream surveys. Visual observation of the
streambanks of Middle Fork and East Fork revealed no evidence of freshwater mussels. Kick-net surveys
and limited bottom sampling conducted within the channel of Middle Fork and East Fork yielded a
variety of aquatic macroinvertebrates.
17
Organisms collected within Middle Fork were identified to Order and include mayflies
(Ephemeroptem), stoneflies (Plecoptera), caddisflies (Trichoptera), blackflies (Diptera), horseflies
(Diptera), waterpennies (Coleoptera), dragonflies (Odonota), hellgrammites (Neuroptera), crayfish
(Decapoda), limpets (Basommatophora), and snails (Gastropoda). A complete list of organisms collected
is located the Natural Systems Report (2000), appended by reference. Surveys done by DWQ in 1993
provide a more complete list of species and their abundance at the benthic monitoring station at Bridge
No. 49.
Organisms collected from East Fork were identified to Order and includes mayflies, stoneflies,
caddisflies, horseflies, dragonflies, hellgrammites, crayfish, limpets, and snails. A complete list of
organisms collected is located the Natural Systems Report (2000), appended by reference. Surveys done
by DWQ in 1993 provide a more complete list of species and their abundance at the benthic monitoring
station at Bridge No. 50.
Limited surveys did not result in documentation of any aquatic amphibian species. Species
expected to occur within the project study area include blackbelly salamander (Desmognathus
quadramaculatus), seal salamander (D. monticola), northern dusky salamander (D. fuscus) and spring
salamander (Gyrinophilus porphyriticus). The stream provides suitable habitat for a few aquatic and
semi-aquatic reptiles and amphibians such as northern water snake (Nerodia sipedon) and queen snake
(Regina septemvittata).
4. Anticipated Impacts to Wildlife
Due to the lack of infringement on natural communities, the proposed bridge replacements will
not result in significant loss or displacement of known terrestrial animal populations. Wildlife movement
corridors are currently limited within the project study area and are not expected to be significantly
impacted by the proposed project. Potential down-stream impacts to aquatic habitat will be avoided by
bridging both systems to maintain regular flow and stream integrity. In addition, temporary impacts to
downstream habitat from increased sediment during construction are expected to be reduced by limiting
in-stream work to an absolute minimum, except for the removal of the portion of the sub-structure below
the water. BMP-BDRs will be followed to minimize impacts due to anticipated bridge demolition.
BMPs for the protection of surface waters and HQW guidelines (Design Standards in Sensitive
Watersheds) should be strictly enforced to reduce impacts. Avoiding all in-stream work during trout
spawning season, October 15 to March 31 will minimize impacts to trout populations.
18
E. SPECIAL TOPICS
1. Waters of the United States
Surface waters within the embankments of Middle Fork and East Fork are subject to jurisdictional
consideration under Section 404 of the Clean Water Act as "Waters of the United States" (33 CFR 328.3).
The waters in both Middle Fork and East Fork, within the project study area, exhibit characteristics of
riverine, upper perennial, unconsolidated bottom, permanently flooded waters which have been at least
partially excavated (R3UBHx) (Cowardin et al. 1979).
All alternatives for this project will bridge the open waters of Middle Fork and East Fork,
negating the need for direct encroachment into riverine waters. Because Middle Fork and East Fork are
protected under the ORW rules, in-water work will be limited to an absolute minimum, with the
exception of the removal of the portion of the substructure below the water.
Anticipated impacts to wetlands and open water areas are estimated based on the amount of each
jurisdictional area within the proposed right-of-way width of 100 feet (30.5 meters); actual areas within
construction limits will be less. Open water areas of Middle Fork and East Fork are included in this table,
although impacts are not expected due to the inclusion of channel-spanning structures. During bridge
removal procedures, NCDOT's BMP's will be utilized, including erosion control measures; therefore it is
anticipated that removing the existing end bents will result in no impact to surrounding surface waters. A
summary of potential jurisdictional impacts is presented below:

Temporary impacts due to bridge demolition have been included in the above table but not in the
alternative analysis. Alternative 1 has the smallest area of open water, approximately 0.10-acre (0.04
hectares) along 225 linear feet (68.6 meters) of stream channel, of which 0.06-acre (0.02-hectare) is
associated with 125 linear feet (38.1 meters) of Middle Fork within the project study area and 0.04-acre
(0.02 hectare) is associated with 100 linear feet (30.5 meters) of East Fork within the project study area.
Alternative 2 has the largest amount of open water area, approximately 0.15-acre (0.06-hectare) along 300
linear feet (91.4 meters) of stream channel, of which 0.08-acre (0.03-hectare) is associated with 150 linear
feet (45.7 meters) of Middle Fork within the project study area and 0.07-acre (0.03-hectare) is associated
with 150 linear feet (45.7 meters) of East Fork within the project study area. Alternative 3 has
approximately 0.13-acre (0.05-hectare) of open water along 270 linear feet (82.3 meters) of stream
channel, of which 0.08-acre (0.03-hectare) is associated with 150 linear feet (45.7 meters) of Middle Fork
within the project study area and approximately 0.05-acre (0.02-hectare) is associated with 120 linear feet
(36.6 meters) of East Fork within the project study area.
Alternative 2 contains the longest section of stream channel and the largest area of open water of
all alternatives. Alternative 2 right-of-way includes approximately 150 feet (45.7 meters) of East Fork,
compared to approximately 120 feet (36.6 meters) in the right-of-way for Alternative 3; rights-of way for
both alternatives include approximately 150 feet (45.7 meters) of Middle Fork. The East Fork segment
20
within the Alternative 3 right-of-way is mainly within the golf course, upstream of Bridge No. 50, where
East Fork has been channelized and narrowed to a width of approximately 18 feet (5.5 meters). The East
Fork segment within the right-of-way associated with Alternative 2 lies downstream of Bridge No. 50,
within the sections of the channel up to 35 feet (11 meters) in width.
Wetlands subject to review under Section 404 of the Clean Water Act (33 U.S.C. 1344) are
defined by the presence of three primary criteria: hydric soils, hydrophytic vegetation, and evidence of
hydrology at or near the surface for a portion (12.5 percent) of the growing season (DOA 1987). Based
on the three parameter approach, two jurisdictional wetlands are present within the project study area and
are associated with Middle Fork (See Figure 6). No jurisdictional wetlands are associated with East Fork
within the project study area.
The first wetland is a vegetated sandy bar located adjacent to Middle Fork, downstream 'of Bridge
No. 49, on the west bank. This area exhibits characteristics of a palustrine wetland with shrub-scrub,
broad-leaved deciduous vegetation and seasonal inundation (PSS1C). The area has evidence of hydric
soils, with gleying evident at a depth of 5 inches (12.7 centimeters) (Munsell color 5G 4/2). This wetland
is approximately 10 feet (3 meters) wide and 90 feet (27.4 meters) long, and vegetated with plume grass,
blackberry, and scattered black willow saplings. Alternative 1 may impact approximately 0.01-acre
(0.004-hectare) of this wetland; Alternative 2 and Alternative 3 may impact approximately 0.02-acre
(0.008-hectare) of this wetland.
The second wetland is a vegetated gravel bar located adjacent to Middle Fork, approximately 50
feet upstream of'Bridge No. 49, on the east bank. This wetland exhibits characteristics of a palustrine
wetland with shrub-scrub, broad-leaved deciduous vegetation and seasonal inundation (PSSIC). The area
has evidence of hydric soils, with gleying evident at a depth of 8 inches (20.3 centimeters) (Munsell color
5G 4/2). This wetland is approximately 18 feet (5.5 meters) wide and 100 feet (30.5 meters) long, and is
vegetated with scattered black locust and red maple seedlings, and blackberry. This area will not be
impacted by any of the proposed alternatives.
a. Permits
This project is being processed as a Categorical Exclusion (CE) under Federal Highway
Administration (FHWA) guidelines. Nationwide Permit (NWT) #23 [33 CFR 330.5(a)(23)] has been
issued by the COE for CEs due to expected minimal impact. DWQ has issued a General 401 Water
Quality Certification for NWP #23. However, use of this permit will require written notice to DWQ. In
21
the event that NWP #23 will not suffice, minor impacts attributed to bridging and associated approach
improvements are expected to qualify under General Bridge Permit 031 issued by the Wilmington COE
District. Notification to the Wilmington COE office is required if this general permit is utilized.
Watauga County is among the twenty-five mountain counties designated as having trout waters.
Although neither Middle Fork nor East Fork carry Trout water designation by DWQ nor are the
Designated Public Mountain Trout Waters, they are know to contain some wild trout. WRC has
requested review of this project per consultation prior to implementation (Personal communication with I
Mickey, May 25, 2000).
b. Mitigation Evaluation
Avoidance - Due to the extent of wetlands and surface waters within the project study area,
avoidance of impacts is not possible. Each alternative contains jurisdictional wetland areas or
open water areas which will be subject to impact. Wetland and stream impacts for each
alternative are previously discussed in Section E and Table 3.0.
Minimization - The alternative corridors presented were developed in part to demonstrate
minimization of wetland and stream impacts. Preliminary wetland determinations within these
corridors will be used to further minimize wetland and stream impacts during the design phase of
this project.
Mitigation - Compensatory mitigation is not proposed for this project due to the limited nature of
project impacts. However, utilization of BMPs is recommended in an effort to minimize impacts,
including avoiding placing staging areas within wetlands. Temporary impacts associated with the
construction activities could be mitigated by replanting disturbed areas with native species and
removal of temporary fill material upon project completion.
2. Protected Species
a. Federal Protected Species
Species with the federal classification of Endangered (E) or Threatened (T), or officially proposed
(P) for such listing, are protected under the Endangered Species Act (ESA) of 1973, as amended (16
U.S.C. 1531 et seq.). The following federal protected species are listed for Watauga County:
22
Common Name Scientific Name Status
Bog turtle Clemmys muhlenburgii T(S/A)
Carolina northern flying squirrel Glaucomys sabrinus coloratus E
Spreading avens Geum radiatum E
Roan Mountain bluet Houstonia montana E
Heller's blazing star Liatris helleri T
Bog Turtle - The bog turtle is a small turtle reaching an adult size of approximately 3 to 4 inches (7.6 to
10.1 centimeters). This otherwise darkly-colored species is readily identifiable by the presence of a bright
orange or yellow blotch on the sides of the head and neck (Martof et. al. 1980). The bog turtle is typically
found in bogs, marshes, and wet pastures, usually in association with aquatic or semi-aquatic vegetation
and small, shallow streams over soft bottoms (Palmer and Braswell 1995). In North Carolina, bog turtles
have a discontinuous distribution in the Mountains and western Piedmont. NHP records do not indicate
that bog turtle has been documented within 3.0 miles (4.8 kilometers) of the project study area.
BIOLOGICAL CONCLUSION: The bog turtle is listed as Threatened due to Similarity of
Appearance [T(S/A)]. T(S/A) species are not subject to Section 7 consultation and a biological
conclusion is not required; however, since potential habitat for this species, consisting of bogs,
marshes, and wet pastures, is not present within the study project area, this project is not expected
to affect bog turtle. NO EFFECT
Carolina Northern Flying Squirrel - The Carolina northern flying squirrel is an isolated, endangered
subspecies of the more wide-ranging northern flying squirrel. Flying squirrels are nocturnal and have a
loose, fully furred fold of skin on each side of the body between the wrists and the ankles that enable the
squirrels to glide from trees to other trees or to the ground for foraging. Carolina northern flying squirrel
can be distinguished from the similar southern flying squirrel (G. volans) by its larger size of 10.2 to 12.0
inches (25.9 to 30.5 centimeters) in total length and by having gray rather than white bases of the ventral
hairs (Weigl 1987).
The Carolina northern flying squirrel typically occurs in spruce-fir forests and mature hardwood forest
adjacent to spruce-fir forests at elevations above 4,000 feet (1,219 meters) (Weigl 1987). Endemic to the
Appalachians of western North Carolina and eastern Tennessee, this subspecies is known from the Great
Smoky Mountains, Roan Mountain, and Mount Mitchell. NHP records do not indicate that Carolina
northern flying squirrel has been documented within 3.0 miles (4.8 kilometers) of the project study area.
23
BIOLOGICAL CONCLUSION: The proposed project is not expected to affect Carolina
northern flying squirrel since elevations within the project study area are a maximum of 3,120
feet (951 meters) above MSL, below the reported minimum elevation of 4,000 feet (1,219 meters)
for this species. Suitable habitat for this species, consisting of spruce-fir and mature hardwood
forest, was not identified within the study project area. NO EFFECT
Spreading Avens - Spreading avens is an erect, densely hairy, perennial herb up to 20 inches (50.8
centimeters) tall. A basal rosette of odd-pinnately compound leaves is produced from a horizontal
rhizome. These leaves are long stalked and terminated by a large kidney-shaped lobe; tiny leaflets are
usually present below the terminal lobe (Kral 1983). Small, sessile, serrated leaves are found on the
flowering stem. Lanceolate sepals and relatively long petal lengths of 0.5 to 0.8 inches (1.3 to 2
centimeters) help differentiate spreading avens from related species (Massey et al. 1983). Bright yellow,
five-petaled flowers approximately 2.4 to 3.1 inches (6.1 to 7.9 centimeters) across are produced from
June to August; these are followed between July and October by hairy achenes with a persistent, straight
style approximately 0.2 inches (0.5 centimeter) long (Massey et al. 1983). Vegetative parts may emerge
in May and persist through October.
Spreading avens usually occurs at elevations greater than 5,000 feet (1,524 meters) above MSL in
mountain grass balds or in grassy clearings in heath balds as well as in crevices of granitic rock. This
species cannot tolerate shading or crowding (Kral 1983). Spreading avens is found in a few northwestern
counties of North Carolina, and in nearby counties of Tennessee. NHP records do not indicate that
spreading avens has been documented within 3.0 miles (4.8 kilometers) of the project study area.
BIOLOGICAL CONCLUSION: The proposed project is not expected to affect spreading avens
since elevations within the project study area are a maximum of 3,120 feet (951.2 meters) above
MSL, below the reported minimum elevation of 5,000 feet (1,524 meters) for this species.
Suitable habitat for this species, consisting of balds or rock outcroppings, was not identified
within the project study area. NO EFFECT
Roan Mountain Bluet - Roan Mountain bluet, formerly treated as a variety of the summer bluet
(Houstonia [=Hedyotis] purpurea), is a low, erect to spreading perennial herb with a squarish stem
typically growing to 6 inches (15.2 centimeters) in height. The leaves are opposite, sessile, rounded
basally but taper to a pointed tip and have smooth, toothless margins. Small, deep purple, tubular flowers
are produced on small terminal clusters in June and July with fruiting occurring in July and August. It
24
differs from the more common H. purpurea by having larger, smooth-edged leaves, and by larger flowers,
capsules, and seeds (Weakley 1993).
Roan Mountain bluet is endemic to the high Blue Ridge mountains of North Carolina and Tennessee,
mostly from 4,200 to 6,300 feet (1,280 to 1,920 meters) above MSL in elevation. It grows in crevices of
rock outcrops as well as in thin, gravelly soils of grassy balds near summit outcrops. (Weakley 1993).
NHP records do not indicate that Roan Mountain bluet has been documented within 3.0 miles (4.8
kilometers) of the project study area.
BIOLOGICAL CONCLUSION: The proposed project is not expected to affect Roan Mountain
bluet since elevations within the project study area are a maximum of 3,120 feet (951.2 meters)
above MSL, significantly below the reported minimum elevation of 4,200 feet (1,280 meters) for
this species. Suitable habitat for this species, consisting of balds, was not identified within the
project study area. NO EFFECT
Heller's Blazing Star - Heller's blazing star is an erect herbaceous perennial with glabrous stems that
reaches heights of 4 to 20 inches (10.1 to 50.8 centimeters). The leaves are simple, linear to lanceolate,
alternate, and arranged spirally along the stem. Leaf size is variable, with a gradual decrease in size up
the stem. The inflorescence consists of compact heads arranged in a raceme-like fashion along the stem.
The heads typically contain seven to ten tubular florets which may be purple to lavender in color. Heller's
blazing star is distinguished from related species by shorter height and relatively short pappus (modified
calyx lobes) half or less the length of the corolla tube. Flowers are produced from July to September, with
fruiting occurring from August to October (Massey et al. 1983).
Heller's blazing star has been found on rocky summits at high elevations in the mountains of western
North Carolina. This species typically is found in full sun growing in shallow, acidic soils on or around
granitic outcrops, ledges, and cliff faces (Kral 1983, Massey et al. 1983). Heller's blazing star is reported
to occur at elevations between approximately 3,500 to 6,200 feet (1,067 to 1,890 meters) above MSL.
NHP records do not indicate that Heller's blazing star has been documented within 3.0 miles (4.8
kilometers) of the project study area.
25
BIOLOGICAL CONCLUSION: The proposed project is not expected to affect Heller's blazing
star since elevations within the project study area are a maximum of 3,120 feet (951 meters)
above MSL, below the reported minimum elevation of 3,500 feet (1,067 meters) for this species.
Suitable habitat for this species, consisting of rocky summits exposed to full sunlight, was not
identified within the project study area. NO EFFECT
Federal species of concern - The USFWS list also includes a category of species designated as "Federal
Species of Concern" (FSC). The FSC designation provides no federal protection under the ESA for the
species listed. The presence of potential suitable habitat (Amoroso 1999, LeGrand and Hall 1999) within
the project study area has been evaluated for the following FSC species listed for Watauga County:

NHP files document two occurrences of the Kanawha minnow within 3.0 miles (4.8 kilometers)
of the project study area. The first occurrence is a 1968 record within the project study area at Bridge No.
49. The second occurrence is a 1995 record from the US 421 bridge over the South Fork New River,
approximately 2.6 miles (4.2 kilometers) downstream of the project study area. No other FSC species has
been documented as occurring within 3.0 miles (4.8 kilometers) of the project study area.
b. State Protected Species
Plant and animal species which are on the North Carolina state list as Endangered (E), Threatened
(T), or Special Concern (SC) receive limited protection under the North Carolina Endangered Species Act
(G.S. 113-331 et seq.) and the North Carolina Plant Protection Act of 1979 (G.S. 106-202 et seq.).
NHP records indicate that the only occurrences of state-listed species are those for the state listed
SC Kanawha minnow previously mentioned under FSC records. No other state-listed aquatic or
terrestrial species with the designations E, T, or SC have been documented within 3.0 miles (4.8
kilometers) of the study project area.
F. Floodplains
Field surveys were performed and a Hydraulic Technical Memorandum, appended by reference,
was produced for this project in May 2000. Watauga County is a participant in the National Flood
Insurance Program. Bridge Nos. 40 and 50 are located in a 100-year Federal Emergency Management
Agency (FEMA) floodplain, Zone A.E. (See Figure 5). A detailed study was prepared and established a
100-year flood elevation of 3,113.2 feet (949.1 meters) for Bridge Nos. 49 and 50. The flood profile
shows the existing structures are overtopped by the 10-year through 100-year flood event.
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.
27
B. Historic Architecture
A field survey of the area of potential affect (APE) was conducted during July 1999. All
structures within the APE were photographed, and later a NCDOT staff architectural historian reviewed
these photos. A final identification and evaluation of the APE was conducted in March 2000 and the
corresponding report is appended by reference. This information was then forwarded to the State Historic
Preservation Officer (SHPO).
One of the properties assessed in the APE was considered to be eligible for inclusion on the
National Register under Criterion C for architecture. The property is not considered eligible under any
other criterion. The "Blair House" is a late 19a' century dwelling with associated outbuildings contained
on a 6.1-acre tract just south of SR 1522 and adjacent to Blairmont Drive
After the selection of Alternative 3 as the Preferred Alternative, the preliminary design was
presented to the State Historic Preservation Office (SHPO) on December 21, 2000 for a determination of
effects. SHPO concurred with the finding of the Blair House as eligible for listing in the National
Register of Historic Places under Criterion C. SHPO also concurred with the boundaries of the Blair
House as shown in Historic Architectural Resources Survey .(Mattson 2000). A concurrence form was
signed on December 21, 2000 stating that Alternative C (Preferred Alternative) would have no effects on
the National Register-listed property located within the project's area of potential effects (See
Correspondence in Appendix).
C. Archaeology
In a memorandum dated March 21, 2001, the SHPO recommended that "a comprehensive survey
be conducted by an experienced archaeologist to identify the presence and significance of archaeological
remains." This work was performed in mid-March 2001 and a report submitted on March 30, 2001. A
letter received from SHPO dated February 06, 2002 stated "During the course of the survey, no sites were
located within the project area. The report author has recommended that no further archaeological
investigation be conducted in connection with this project. We concur with this recommendation since
the project will not involve significant archaeological resources" (See Correspondence in Appendix).
D. Parks/Recreational Facilities
The Lee and Vivian Reynolds Greenway is located northwest of Bridge No. 49 and SR 1522,
between Middle Fork and Lowes Home Improvement Center. The portion of the greenway contained in
this described area is known as "The Loop" and currently, plans are underway to connect the loop to the
28
remainder of the greenway which is located north of the project study area. When this connection is
made, there will be approximately 3 miles (4.8 kilometers) of walking paths available in the Reynolds
Greenway.
The parking area located adjacent to SR 1522 and the walking paths themselves will not be
impacted; however, Alternative 2 and Alternative No. 3 (Preferred) will impact approximately 0.22-acre
(0.09-hectare of maintained open area associated with the greenway. The Town of Boone has suggested
that a pedestrian walkway could be added to the north side of SR 1522 from Blair Drive and Blairmont
Subdivision to the Reynolds Greenway to allow easier and safer access by local citizens.
The Boone Golf Club is located south of SR 1522, adjacent to Bridge Nos. 49 and 50. This
course is a public, 18 hole course that averages approximately 40,000 rounds per year. Alternative No. 3
(Preferred) will impact approximately 0.81-acre (0.33-hectare) of this course; specifically, in the tee area
of the 3`d hole. This hole is currently a par 3 with a distance of approximately 166 yards (151.8 meters).
VII. ENVIRONMENTAL EFFECTS
The project is expected to have an overall positive impact on the local area. Replacement of two
inadequate bridges will result in safer and more efficient 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 NCDOT 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 effect on individual families or communities is anticipated. Right-of-way acquisition
will be limited. No relocatees are expected with implementation of the proposed alternative.
No adverse effect on public facilities or services is anticipated. The project is not expected to
adversely affect social, economic, or religious opportunities in the surrounding area.
29
No geodetic survey markers will be impacted.
The project limits are within the City of Boone zoning jurisdiction. The areas affected by the
project are committed to urbanized land use consisting of urban commercial, residential and industrial
uses. Therefore, the project is exempt from the Farmland Protection Policy Act.
This project is in 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.
This project is located in Watauga County, which has been determined to be in compliance with
the National Ambient Air Quality Standards. 40 CFR Part 51 is not applicable because the proposed
project is located in an attainment area. This project is not anticipated to create any adverse effects on the
air quality of this attainment area.
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 State Implementation Plan (SIP) for air quality in compliance with 15 NCAC2D.0520.
This evaluation completes the assessment requirements for highway traffic noise of Title 23, Code of
Federal Regulations (CFR), Part 772 and for air quality (1190 Clean Air Act Amendments and the
National Environmental Policy Act) and no additional reports are required.
No properties determined as eligible for Listing on the National Register will be impacted by the
Preferred Alternative.
A search was performed of the project study area utilizing the ASTM Standard Practice for
Environmental Site Assessments (E 1527-97). This search included the NPL (National Priority List),
CERCLIS (Comprehensive Environmental Response, Compensation, and Liability Information System),
RCRIS (Resource Conservation and Recovery Information), and UST (Petroleum Underground Storage
Tank Database) as well as other applicable databases. The results of this search documented no mapped
sites found on the target site or within the ASTM search radius. The Executive Summary for this search
is found in the Appendix.
30
Watauga County is a participant in the National Flood Insurance Regulatory Program (FIRM).
The approximate 100-year floodplain in the project area is shown on Figure 5. The amount of floodplain
area to be affected is not substantial.
There are no practical alternatives to crossing the floodplain area. Any shift in alignment will
result in a crossing of about the same magnitude. All reasonable measures will be taken to minimize any
possible harm.
The project will not increase the upstream limits of the 100-year floodplain.
On the basis of the above discussion, it is concluded that no significant adverse environmental
effects will result from implementation of the project.
VIII. PUBLIC INVOLVEMENT
Public involvement for this project initially involved compiling a database of property owners,
area business persons and local public officials. This database was used to send out Newsletter No. I on
June 8, 2000 announcing the project and detailing the upcoming Local Officials Meeting and Citizens
Information Workshop. The meeting and workshop were held on June 26, 2000 at the Moose Lodge
located on SR 1522. Four local officials attended the meeting, with the majority of comments received
summarized below:
• The detour route proposed with Alternative 1 is not feasible due to curves/grade of the detour
roads and these roads would require some maintenance before they could be utilized as a
detour route; and
• Concern was expressed over Alternative 3 and its proximity and impacts to the Boone Golf
Club.
Approximately eight citizens attended the workshop, with the majority of comments received
summarized below:
• The detour route associated with Alternative 1 was discussed as being too "steep and curry"
for school buses and emergency vehicles;
• Alternative 2 was favored by the manager of the Boone Golf Club;
31
• Alternative 3 was favored overall by most residents including representatives from the Moose
Lodge;
• Representatives from the Boone Golf Club were against this alternative as it would impact
one and possibly two holes of their course.

Raleigh, North Carolina 27611-5201
Dear Mr. Gilmore:
According to your letter of December 8, 1999, received December 17, 1999, the North Carolina
Department of-Transportation is proposing the following. four bridge replacement projects:
o B-3066; replacement of Bridge No. 49 and Bridge No. 50 on SR 1522 over Middle
Fork and East Fork, respectively, tributaries of the South Fork New River, Watauga
County, North Carolina (our Log Number 4-2-00-034)
o B-3533; replacement of Bridge No. 43 on SR 1306 over Howard's Creek in the South
Fork New River system, Watauga County, North Carolina (our Log Number
4-2-00-035)
o B-3536; replacement of Bridge No.12 on SR 1549 over Flannery Fork Creek in the
South Fork New River system, Watauga County, North Carolina (our Log Number
4-2-00-036)
o B-3405; replacement of Bridge No 65 on SR 1361 over Big Horse Creek in the North
Fork New River system, Ashe County, North Carolina (our Log Number 4-2-00-037)
As requested, we have reviewed the proposed projects and are providing the following comments
in accordance with the provisions of Section 7 of the Endangered Species Act of 1973, as
amended (16 U.S.C. 1531-1543) (Act) and the Fish and Wildlife Coordination Act, as amended
(16 U.S.C. 661-667e)..
Enclosed is a list of the federally endangered and threatened species known from Ashe and
Watauga Counties, North Carolina. A federally threatened plant species--Virginia spiraea
L
(Spiraea virginiana )--is known to occur in the New River system in Ashe County and may also
occur in this river system in Watauga County. Accordingly, even though this species does not
appear on the species list for Watauga County, surveys should be conducted to determine if this
species may potentially be affected by the three proposed projects in Watauga County. and"the
project in Ashe County. The legal responsibilities of a Federal agency or its designated
non-Federal representative under Section 7 of the Act are on file with the Federal Highway
Administration.
The enclosed list also includes species of Federal concern that are currently tinder status review
by the U.S. Fish and Wildlife Service which may occur in the areas potentially affected by the
proposed projects.. Species of Federal concern are.notlegally protected under the Act and are not
subject to any of its provisions, including Section.7; runless they are formally proposed or listed
as endangered or threatened. We are including these species in our response to give you advance
notification and to request your assistance in protecting them if any are found in the vicinity of
your projects.
The information that accompanied your letter concerning these projects provided information
relating only to the removal of the existing bridges.-According to this information, no temporary
fill will be associated with any of the four projects and the existing structures will be moved in
such a manner that no components will be dropped into the water. However, your letter also
stated that construction will be scheduled to avoid.in-stream activities in order to minimize,
..impacts in trout waters according to dates to be determined by the North Carolina Wildlife=
Resources Commission.. What in-stream construction activities will take place- and what
potential impacts are associated-with these activitiesT We recommend that no heavy equipment
be operated in the stream channel and that any cutting. and removal of woody vegetation along
the stream banks be avoided to the maximum extent possible. We also recommend that any
existing fill in the flood plain associated with the existing structures and approaches be removed.
These areas should be returned to the natural elevation of the flood plain in order to restore its
natural function and to minimize the potential for stream-bank and channel scouring that may
occur during storm flows as a result of any constriction of the flood plain or stream channel
associated with the existing structures.
As stated above, the information that you provided addressed only the removal of the existing
bridges; no information was provided concerning the types of structures that will replace the
existing bridges or what measures will be implemented to minimize the potential effects
associated with the new structures and their construction. We recommend that the existing
structures be replaced with bridges. We recommend that each new bridge design include
provisions for the roadbed and deck drainage to flow through a vegetated buffer prior to reaching
the affected stream. This buffer should be large enough to alleviate any potential effects from the
run-off of storm water and pollutants. The bridge designs should not alter the natural stream and
stream-bank morphology or impede fish passage. Any piers or bents should be placed outside
the bank-full width of the streams. The bridges and approaches should be designed to avoid any
fill that will result in damming or constriction of the channel or flood plain. If spanning the flood
plain is not feasible, culverts should be installed in the flood plain portion of the approaches in
order to restore 'some of the hydrological functions of the flood plain and reduce high velocities
of flood waters within the affected areas. We recommend that erosion- and sedimentation-
control measures be in place prior to any ground-disturbing activities. Wet concrete should
never be allowed to come into contact with the stream.
We appreciate the opportunity. to. provide these comments. If you have any questions or .
concerns, please contact Mr. John'Fridell of our staff at 828/258-3939, Ext. 225. We have
assigned each of these projects a separate log number, please reference these numbers in any
future correspondence concerning these projects.

Status Definition
Endangered A taxon "in danger of extinction throughout all or a significant portion of its range."
Threatened A taxon "likely to become endangered within the foreseeable future throughout all or a
significant portion of its range."
December 20, 1999 Page 2 of 3
FSC A Federal species of concem--a species that may or may not be listed in the future (formerly
C2 candidate species or species under consideration for listing for which there is insufficient
information to support listing).
T(S/A) Threatened due to similarity of appearance (e.g., American alligator )-a species that is
threatened due to similarity of appearance with other rare species and is listed for its protection.
These species are not biologically endangered or threatened and are not subject to Section 7
consultation.
Species with 1, 2, 3, or 4 asterisks behind.them indicate historic, obscure, or incidental records.
*Historic record - the species was last observed in the county more than 50 years ago.
**Obscure record - the date and/or location of observation is uncertain.
***IncidentaUmigrant record - the species was observed outside of its normal range or habitat.
****Historic record - obscure and incidental record.
'In the November 4, 1997, Federal Register (55822-55825); the northern population of the bog turtle (from New
York south to Maryland) was listed as T (threatened), and the southern population (from Virginia south to
Georgia)was listed as T(S/A) (threatened due to similarity of appearance). The T(S/A) designation bans the
collection and interstate and international commercial trade of bog turtles from the southern population. The T(S/A)
designation has no effect on land-management activities by private landowners in North Carolina, part of the
southern population of the species. In addition to its official. status as T(S/A), the U.S. Fish and Wildlife Service
considers the southern population of the bog turtle as a Federal species of concern due to habitat loss.

Dear Mr. Gilmore:
Reference is made to your request dated December 8, 1999, for comments regarding the
proposed Group XXII Bridge Replacement Projects in Watauga and Ashe Counties, North
Carolina. The projects involve the replacement of 5 bridges at 4 separate locations. The,
replacement of Bridge Numbers 49 and 50 is located.on SR 1522, over.Middle Fork and East
Fork (tributaries to the New River), southeast of Boone, Watauga County, TIP No. 3066 (Action
ID 200020363). Bridge Number 43 is located on SR 1306, over Howard's Creels, northeast of
Boone, Watauga County, TIP No. 3533 (Action ID 200020364). Bridge Number 12 on SR 1549
over Flannery Fork Creek, in Boone, Watauga County, TIP No. B-3536 (Action ID 200020365).
Finally, Bridge No. 65 on SR 1361 over Big Horse Creek, northwest of Lansing, Ashe County,
TIP No. B-3405 (Action ID. 199921349).
We have reviewed the subject document and have determined that based upon a review of the
information provided and available maps, it appears that the projects may impact jurisdictional
waters of the United States and their associated wetlands subject to our regulatory authority
pursuant to Section 404 of the Clean Water Act. Any discharge of excavated or fill material into
waters of the United States and/or any adjacent wetlands that maybe present within the project
limits will require Department of the Army (DA) permit authorization. Department of the Army
authorization will be determined based upon the extent of jurisdictional area impacted by the
project, project design and construction limits. Should the project be eligible for nationwide.
permit authorization, you must coordinate with the North Carolina Wildlife Resources
Commission to ensure that the project will not have an adverse impact upon trout resources.
Furthermore, it is recommended that you coordinate with Mr. Jay Wild [phone] to ensure
that TIP No. B-3066 in Watauga County does not occur within an area of the New River which
is designated as a Wild and Scenic River. Nationwide permits are not available within areas
designated as a Wild and Scenic River.
Finally, all bridge demolitions should adhere to the latest NCDOT Policy:. Bridge'Demolition
and Removal in Waters of the United States (BDR Policy), including the Best Management
Practices for Bridge Demolition and Removal.
Due to the limited information provided regarding. the extent of jurisdictional impacts
associated with the project, we will be unable. to provide specific comments regarding DA permit
requirements until additional data are furnished regarding the-limits of the jurisdictional impacts
within construction limits of the proposed project.. When this information becomes available, it
should be forwarded to our office for review and comment, as well as a determination. of DA
permit eligibility.
Any questions related to DA permits for these projects should be addressed to
Mrs. Jean B. Manuele, Raleigh Field Office, telephone.[phone],. Extension 24.
Sincerely,

E. David Franklin

Re: Replacement of Bridges No. 49 and 50 on SR 1522 over Middle Fork and East Fork of New River,
TIP B-3066, Boone, Watauga County, ER 01-8276
Dear Ms. Leight:
Thank you for your letter of December 6, 2000, concerning the above project.
In a letter to the North Carolina Department of Transportation dated June 9, 2000, we concurred with NCDOT's
finding of the Blair House as eligible for listing in the National Register of Historic Places under Criterion C for
architecture as a well-preserved rare surviving example of late nineteenth century domestic architecture in Watauga
County. We also concurred with the boundaries as noted on page 11 of the structures report.
Archaeological site 31WT193 appears to be in the area of the project. We recommend that a comprehensive survey be
conducted by an experienced archaeologist to identify the presence and significance of archaeological remains that may
be damaged or destroyed by the proposed project. Potential effects on unknown resources should be assessed prior to
the initiation of construction activities.
A list of archaeological consultants who have conducted or expressed an interest in conducting contract work in North
Carolina is available on our website, http://?vww.arch.dcr.state.nc.us/consults.htm. The archaeologists listed, or any
other archaeologist, may be contacted to conduct the investigation.
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.
Thank you for your cooperation and consideration. If you have questions concerning the above comment, contact

SUBJECT: Rare Species, High Quality Natural Communities, and
Significant Natural Heritage Areas at Five Proposed Bridge
Replacement Sites in Ashe and Watauga Counties, North
Carolina.
Dear Ms. Leight:
The NC Natural Heritage Program (NCNHP) does not have a record of high quality
natural communities, state park and recreation areas, or Significant Natural Heritage
Areas at or within a 1.0 mile radius of the proposed bridge replacement project sites
in Ashe and Watauga counties, North Carolina. However, there are records of rare
aquatic species within a 1.0 mile radius of three of the sites. Table 1 (attached) gives
the particulars of my site reviews. Habitat requirements are also stated. I do not have
any information about trout stream designations. The NC Wildlife Resources
Commission or US Fish and Wildlife Services may have this information.
Enclosed are lists of rare species known to exist in Ashe and Watauga counties. If
habitat for any of these species exist at the sites, they may be present there. Consultant
acquired knowledge of the existing habitat should determine if a survey is necessary.
Please do not hesitate to contact me at the address below or call me at (919) 715-
8703 if you have any questions or need further information.

NC NATURAL HERITAGE PROGRAA1 COUNTY SPECIES LIST COVER SHEET
The county species list from the NC Natural Heritage Program is a listing of the elements of natural diversity (rare species,
exemplary natural communities, and special animal habitats) known to occur in a county. The information on this printout is
compiled from a variety of sources, including field surveys, museums and herbaria, literature, and personal communications. The
Heritage Program's Biological and Conservation Database (BCD) is dynamic, with new records being added and old records being
revised as new information is received. The BCD was developed and is maintained using methodology developed by The Nature
Conservancy. The enclosed list cannot be considered a definitive record of natural heritage elements, and it should not be
considered a substitute for field surveys. When this information is used in any document, we request that the printout date be
given and that the NC Natural Heritage Program be credited.
This cover sheet explains the four columns of status codes that are given on the right-hand side of the county status list.
. STATESTATUS
CODE STATUS CODE STATUS
E Endangered P_ Proposed (E, T, or C)
T Threatened SR Significantly Rare
SC Special Concern EX Extirpated
C Candidate
Plant statuses are determined by the Plant Conservation Program (NC Department of Agriculture) and the Natural Heritage
Program (NC Department of Environment and Natural Resources). E, T, and SC species are protected by state law (Plant
Protection and Conservation Act, 1979). C and SR designations indicate rarity and the need for population monitoring and
conservation action.
Animal statuses that indicate state protection (E, T, and SC) are published in Endangered Wildlife of North Carolina, March 16,
1992, Nongame and Endangered Wildlife Program (NC Department of Environment and Natural Resources). SR and EX statuses
are Natural Heritage Program designations. SR indicates rarity and the need for population monitoring and conservation action.
FEDERAL STATUS
This status is designated by the US Fish and Wildlife Service. Federally listed Endangered and Threatened species are protected
under the provisions of the Endangered Species Act of 1973, as amended through the 100th Congress. Unless otherwise noted,
definitions are taken from the Federal Register, Vol. 56, No. 225, November 21, 1991 (50 CFR Part 17).
CODE STATUS DEFINITION
LE Endangered A =on "in danger of extinction throughout all of a significant portion of its range."
LT Threatened A taxon "likely to become an endangered species within the foreseeable future throughout all of a
significant portion of its range."
P_ Proposed A taxon proposed for official listing as endangered or threatened.
C Candidate A taxon under consideration for which there is sufficient information to support listing. This category was
formerly designated as a Candidate 1 (Cl) species.
FSC Federal "Species of Concern" (also called "Species at Risk"). Formerly defined as a taxon under
consideration for which there is insufficient information to support listing; formerly designated as a
Candidate 2 (C2) species. Currently, the US Fish and Wildlife Service does not recognize this as an
official designation.
T(SIA) Threatened due to Similarity of Appearance. The Endangered Species Act authorizes the treatment of a
species (subspecies or population segment) as threatened even though it is not otherwise listed as
threatened if: (a) The species so closely resembles in appearance a threatened species that enforcement
personnel would have substantial difficulty in differentiating between the listed and unlisted species; (b) the
effect of this substantial difficulty is an additional threat to a threatened species; and (c) such treatment of
an unlisted species will substantially facilitate the enforcement and further the policy of the Act. The
American Alligator has this designation due to similarity of appearance to other rare crocodilians. The
Bog Turtle (southern population) has this designation due to similarity of appearance to Bog Turtles in the
threatened northern population.
-- GLOBAL AND STATE RANKS
These ranks are determined by The Nature Conservancy's system of measuring rarity and threat status. "Global" refers to
worldwide ranks and "State" to statewide ranks.
STATE RANK DEFINITIONS
S1 Critically imperiled in North Carolina because of extreme rarity or otherwise very vulnerable to extirpation in the state.
S2 Imperiled in North Carolina because of rarity or otherwise vulnerable to extirpation in the state.
S3 Rare or uncommon in North Carolina.
S4 Apparently secure in North Carolina, with many occurrences.
S5 Demonstrably secure in North Carolina and essentially ineradicable under present conditions.
SA Accidental or casual; one to several records for North Carolina, but the state is outside the normal range of the species.
SH Of historical occurrence in North Carolina, perhaps not having been verified in the past 25 years, and suspected to be still
extant in the state.
SR Reported from North Carolina, but without persuasive documentation for either accepting or rejecting the report.
SX Believed to be extirpated from North Carolina.
SU Possibly in peril in North Carolina, but status uncertain; more information is needed.
S? Unranked, or rank uncertain.
B Rank of breeding population in the state. Used for migratory species only.
_N Rank of non-breeding population in the state. Used for migratory species only.
_Z_ Population is not of significant conservation concern; applies to transitory, migratory species.
GLOBAL RANK DEFINITIONS
G1 Critically imperiled globally because of extreme rarity or otherwise very vulnerable to extinction throughout its range.
G2 Imperiled globally because of rarity or otherwise vulnerable to extinction throughout its range.
G3 Either very rare and local throughout its range, or found locally in a restricted area.
G4 Apparently secure globally, although it may be quite rare in parts of its range (especially at the periphery).
G5 Demonstrably secure globally, although it may be quite rare in parts of its range (especially at the periphery).
GH Of historical occurrence throughout its range.
GX Believed to be extinct throughout its range.
GU Possibly in peril, but status uncertain; more information is needed.
G? Unranked, or rank uncertain.
G_Q Of questionable taxonomic status.
T_ Status of subspecies or variety; the G rank refers to the species as a whole.
ADDITIONAL DEFINITIONS
Elements following county names marked with one or two asterisks indicate obscure or historic records.
* Obscure record: the date the element was last observed in the county is uncertain.
** Historic record: the element was last observed in the county more than 20 years ago.
Scientific and'common names listed in parentheses are synonyms listed in US Fish and Wildlife Service, 1992, Endangered and
Threatened Species of the Southeastern United States (The Red Book).

Subject: NCDOT Bridge Replacement Projects
• B-3066, Bridges No. 49/50 on SR 1521, Watauga Co.
• B-3533, Bridge No. 43 on SR 1306, Watauga Co.
• B-3536, Bridge No. 12 on SR 1549, Watauga Co.
• B-3405, Bridge No. 65 on SR 1361, Ashe'Co.
Dear Ms. Leight:
This is in response to your August 19, 1999 letter requesting scoping comments for the above
referenced bridge replacements. While it is not known how these bridges will be replaced, it is our
recommendation that all of the bridges be replaced with another spanning structure. We would be
opposed to the use of culverts, either CMP or RCBC, since culverts are often improperly installed,
creating fish migration blockages, excessive damage to riparian zones, and channel morphology changes
that damage instream aquatic habitat. Because plans are incomplete for these bridge replacements, we
have not identified any additional concerns at this time. However, once plans are finalized for these
projects and submitted for review during the 404/401 permit process, we may offer additional
recommendations to lessen impacts to aquatic resources.
In order for biological staff of the North Carolina Wildlife Resources Commission to provide a
meaningful review, the environmental document prepared for these projects should include the following
information:
1) Description of fishery and wildlife resources within the project area, including a listing of
federally or state designated threatened, endangered, or special concern animal and plant species.
Contact is the Ms. Susan Reece Giles of the North Carolina Natural Heritage Program (919/733-
7701) and Mr. Mark Cantrell of the US Fish and Wildlife Service (704/258-3939, ext. 227).
2) Description of waters and/or wetlands affected by the project.
3) Project map identifying wetlands and streams. Identification of wetlands may be accomplished
through coordination with the U.S. Army Corps of Engineers (Steve Chapin, 704/271-4014). If
the Corps is not consulted, the person delineating wetlands should be identified and criteria listed.
4) Description of project activities that will occur within wetlands and stream channel alterations.
Acreages of wetlands impacted and linear feet of stream channels to be relocated, channelized or
culverted by each alternative designs should be listed. Project sponsors should indicate whether
the Corps has been contacted to determine the need for a 404 Permit under the Clean Water Act.
Contact is Mr. Steve Lund at 704/271-4857.
5) Description of project site and non-wetland vegetative communities.
6) The extent to which the project will result in loss, degradation, or fragmentation of wildlife
habitat.
7) Any measures proposed to avoid or reduce impacts of the project or to mitigate for unavoidable
habitat losses. A mitigation plan should be prepared and submitted along with the EA for review
by permitting agencies.
8) A list of document preparers which shows each individual's professional background and
qualifications.
All of these projects will impact waters supporting trout. Howard's Creek (B-3533) and Big
Horse Creek (B-1361) are Designated Public Mountain Trout Water (DPMTW) managed for stocked and
wild trout by the North Carolina Wildlife Resources Commission (NCWRC). Flannery Fork (B-3536),
Middle Fork and East Fork (B-3066) are not DPMTW, however these streams do contain some wild trout.
All of the streams carry the NC Division of Water Quality Trout Jr) designation. During the permitting
process for these bridge replacements, we will recommend that instream work and land disturbance
within the 25-foot wide buffer zone be prohibited during the trout spawning season of October 15 through
March 31 to protect the egg and fry stages of trout from off-site sedimentation during construction. We
probably will have additional recommendations once final plans for each project is submitted for review.
Concerning trout stream classifications, the NCWRC and NC Division of Water Quality both
classify trout waters, which can be confusing. Streams classified by the NCWRC as DPMTW are based
on public access for fishing. Several classifications exist for NCWRC management purposes, Hatchery
Supported for streams receiving stocked fish and Wild for streams containing populations maintained by
natural reproduction. A complete listing of streams by county and by regulation managed by the
NCWRC can be found in the 1999-2000 NC Inland Fishing, Hunting & Trapping Regulations Digest,
available at most hunting/fishing stores and Wal Mart and Kmart. Streams classified as Tr by DWQ are
based on their ability to support and maintain trout populations and are not necessarily open to public
fishing. Nearly every stream in the mountains contains the DWQ Tr designation.
Thank you for the opportunity to comment on these bridge replacements during the early phase of
the scoping process. If you have any questions concerning these comments please contact me at 336/366-
2982.

RE: Comments for Group XXII Bridge Replacement Projects, TIP: B-30661 B-3533, B-3536
(Watauga County) and B-3405 (Ashe County)
Dear Mr. Gilmore:
The North Carolina Wildlife Resources Commission has received your letter requesting
our comments on the above projects. It is our understanding that you desire to prepare a Federal
Categorical Exclusion for the four bridge replacement sites.
Our main concern with the proposed projects is that it is unclear how these bridges will
be replaced. We do recommend that they be replaced with spanning structures and not with
culverts. Each of the streams involved supports trout species and will require a moratorium
during various trout spawning seasons. This moratorium should be from October 15 through
April 15 to protect the egg and fry stages of brown, brook and rainbow trout.
The following information about the associated streams may be helpful in your
determinations.
1. B - 3066 - Waters under Bridge #49 are Designated Public Mountain Trout
Water and support wild brown trout and rainbow trout. Waters under Bridge
950 support wild brown trout and rainbow trout.
2. B - 3533 -Waters under Bridge #43 are Designated Public Mountain Trout
Water/Hatchery Supported and support wild brown and rainbow trout
populations.

3. B - 3536 -Waters under Bridge #12 support wild rainbow and brown trout
. populations.
2
4. B - 3405 - Waters under Bridge 465 are high quality Designated Public
Mountain Trout Water. Both wild and hatchery supported trout utilize these
waters.
If concrete will be used, work must be accomplished so that wet concrete does not
contact stream water. This will lessen the chance of altering the stream's water chemistry and
causing a fish kill. Heavy equipment should be operated from the bank rather than in the stream
channel in order to minimize sedimentation and reduce the likelihood of introducing other
pollutants into the stream. Stringent erosion control measures should be installed where soil is
disturbed and maintained until project completion. 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. The flood plain should not be modified or restricted by the
replacement structure or by maintenance activities. Storm water should be diverted from the
bridge(s) as sheet flow instead of piped or channeled to the stream.
Thank you for the opportunity to comment on this project during the early stages of your
planning. If I can be of further assistance, please contact me at 336/769-9453.

In response to your correspondence with Mr. Townsend, I would like to provide the following
information for your company.
Bridges 49 and 50 are crossed eight times each day by four buses. Closing these bridges during school
operating hours would cause considerable hardship in routing buses, and would significantly increase the
bus ride times for students living in the area. However, with enough advance warning, we could work
around this closure.
Bridge 43 across Howard's Creek is crossed five times per day by three buses. Closing this bridge during
school operating months would mean that approximately 60 students would not have bus service because
there is no practical way to route around this closure.
Bridge 12 across Winkler's Creek is crossed four times per day by two buses. Again, this would involve
considerable re-routing of buses and a significant increase in ride times for students. However, this
closure is probably the easiest to deal with in terms of number of students affected.
If I can provide any further information, please call.

After receiving-your -letter concerning information on emergency
services that would-be-affected-with the proposed bridge replacement
projects, I have met with-Boone Fire, Meat Camp VFD and Watauga
Medics.
To answer.the first-question, yes there are emergency services
located within .5-n le-of the proposed replacements. Boone Fire
Department StatiurrII and Watauga Medics Base II are located less than .5
mile from Bridge 49 & 50.
To answer the second question, Boone Fire Department would not
be able to make the turn onto Blairmont Drive if alternative route No. 3 is
used. Meat Camp-VFD;-Watauga Medics and Boone FD also request the
weight limit for apparatus on. temporary bridges.
If you have-any. questions, please feel free to contact me at the
office.

Re: Bridge Replacement Projects
Dear Mr. Gilmore:

In response to your December 15, 1999 memo please consider the
following comments. Generally speaking, bridge replacements are
u;.-Icome, in that it is assumed the results will be improved safety and
traffic flow. However, during demolition and construction, it is
imperative that the streams be protected from sedimentation or other
pollution, and that access for emergency vehicles not be impeded.
Additionally, the citizens of Watauga County are interested in and
v,illling to participate fully in government projects so "going the extra
mile" in regard to providing public information and seeking citizen
input would be prudent. Specific comments for each project are as
follows.
- B-3066. Proximity to the Boone Golf Course and Watauga Medical
Center, as well as heavy traffic on the road are concerns. These
bridges are Lvithin the Boone town limits. Comments should besought
from the Town of Boone.
- B-3533. Close proximity to a private school should be considered.
Howard's Creek at that point is classified High Quality Waters (HQW) by
the N.C. Environmerital Management Commission.
- B-3536. Close proximity to the municipal water supply intake should
be a strong consideration. This bridge is within the Boone town limits.
Comments should be sought from the Town of Boone-
- B-3405. This project is in Ashe County.
If you need more information, please contact me.

Bridge No. 49 on SR 1522 over Middle Fork to New River
Watauga County
Division 11
Federal-Aid Project No. 8.2750801
State Project No. MABRSTP-1522 (2)
Description: This project contains a bridge removal over Waters of the U.S. Bridge No. 49
is located on SR 1522 over Middle Fork to New River in Watauga County. The deck for the
superstructure is steel plank on I-Beams. The substructure consists of timber end bents. The
deck, curbs and end bents will be removed without dropping them into the Waters of the US
during construction. No temporary fill associated with the removal of this bridge is anticipated.
Bridge No. 49 was built in 1956. The structure includes 1 span totaling 44'-3" in length.
The bridge has a sufficiency rating of 36.9 out of 100. The posted weight limit is 31 tons for
single vehicles and 34 tons for truck-tractors semi-trailers.
Calculations:
• Superstructure: No temporary fill associated with removal of the superstructure is
anticipated since the deck is composed entirely of steel ahd'timMr'and will be removed in
such a manner that no components will be dropped in the water.
Say 0 yd3 from superstructure
• Substructure: No temporary fill associated with removal of the substructure is anticipated
since the end bents are composed entirely of timber and will be removed in such a manner
that no components will be dropped in the water.
Say 0 yd3 substructure
TOTAL: 0 yda of temporary fill in Waters of the US.
• Moratorium: Construction will be scheduled to avoid instream activities to minimize
impacts in trout waters per dates to be determined by the North Carolina Wildlife
Resources Commission.
Section 7 Consultation: None anticipated.
