~ No. 142 over Abbott's Creek on SR 1741 in Davidson County, Federal Aid Project
No. BRSTP-1741(2), State Project No. 8.2604801, WBS Element: 33456.1.1,
Division 9, TIP B-4100
Dear Sir:
The North Cazolina Department of Transportation (NCDOT) proposes to replace Bridge No. 142
over Abbott's Creek on SR 1741. The existing Bridge No. 142 has an overall length of 106-feet and
a cleaz deck width of 24-feet. The existing two-lane bridge has a reinforced concrete deck on I-
beams supported by reinforced concrete caps and timber piles at approximate 35-foot centers. The
bridge has a sufficiency rating of 34.6 compazed to 100 for a new structure. It is proposed that the
current bridge be replaced with a single span steel plate girder bridge, 140-feet in length, and will
require two temporary causeways to be placed in Abbott's Creek in order to remove the 2 existing
bridge bents in the water. The new bridge will be 130-feet in length with a maximum clear roadway
width of 40-feet. New approaches to the bridge will provide 12-foot travel lanes with 8-foot
shoulders including 2-foot paved shoulders. During construction traffic will be maintained with a
temporary detour located on the north side of the bridge. Please fmd enclosed the pre-construction
notification, permit drawings, design plan sheets, and a letter of acceptance from the Ecosystem
Enhancement Program (EEP) for the proposed project. A Categorical Exclusion (CE) was
completed for this project in Apri12005 and distributed shortly thereafter. Additional copies are
available upon request.
IMPACTS TO WATERS OF THE UNITED STATES
General Description: The project is located in the Yadkin-Pee Dee River Basin, subbasin 03-07-07
with a Hydrologic Unit Code of 03040103. Abbott's Creek has a Division of Water Quality (DWQ)
stream index number of 12-119-1 and is a large tributary to High Rock Lake. A best usage
classification of WS-III has been assigned to Abbott's Creek. There are wetlands in the project area.
A Jurisdictional Determination (Action ID. 200420754) from the U.S. Army Corps of Engineers was
given for the wetlands on April 18, 2006.

RALEIGH NC 27699-1598

No designated High Quality Waters (HQW), Outstanding Resource Waters (ORW), WS-I or WS-II
waters occur within one-mile of the project area. Abbott's Creek is not listed on the 2006 List of
impaired waters [Section 303(d)] for the Yadkin-Pee Dee River Basin nor does it drain into any
303(d) waters within 1-mile of the project area.
Permanent Impacts: Construction of the new bridge will require both excavation and filling of
portions of wetlands located on the north side of the new bridge. There will be 0.04-acre of
excavation for the installation of a lateral base ditch. There will be 0.06-acre of permanent fill due
to the installation of the lateral base ditch. The total permanent impacts to riverine wetlands will be
0.1-acre. There will also be 39-feet of stream impacts to Abbott's Creek. The permanent stream
impacts are from the need to stabilize the stream bank along the entire width of the bridge.
Temporary Impacts: There will be temporary impacts associated with the construction of Bridge No.
142. There will be 0.04 acres of temporary fill in wetlands due to the temporary detour. There will
be 0.02 acre of temporary impacts to surface waters due to the use of a temporary causeway. The
causeway will be used to remove the bents from the old bridge.
Utility Impacts: There will be no jurisdictional impacts from utility relocations due to this bridge
replacement project.
Bridge Demolition: Bridge No. 142 has a reinforced concrete deck on I-beams supported by
reinforced concrete caps and timber piles at approximately 35-foot centers. The bridge has an
overall length of 106-feet and is 24-feet wide. The bridge will be removed without dropping any
components into waters of the United States. NCDOT's Best Management Practices for Bridge
Demolition and Removal will be followed.
RESTORATION PLAN
Following construction, all material used in the construction of the new bridge as well as the detour
bridge will be removed. The impacted areas associated with the bridge are expected to recover
naturally, since the natural streambed and plant material will not be effected. NCDOT does not
propose any additional planting in this area. Class I riprap and filter fabric will be used for bank
stabilization. Pre-project elevations will be restored. NCDOT will restore the wetlands to their pre-
proj ect contours. After the detour's purpose has been served the material used for installation of the
temporary detour bridge will be removed and the areas will be restored to original contours.
REMOVAL AND DISPOSAL PLAN
The contractor will be required to submit a reclamation plan for the removal of and disposal of all
material off-site at an upland location. The contractor will use excavation equipment for removal of
any earthen material. Heavy~iuty trucks, dozers, cranes and various other pieces of mechanical
equipment necessary for construction of roadways and culverts will be used on site. All material
placed in the stream will be removed from the stream at that time. The contractor will have the
option of reusing any of the materials that the engineer deems suitable in the construction of project.
After the erosion control devices are no longer needed, all temporary materials will become the
property of the contractor.
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 May 10, 2007, the United States Fish and
Wildlife Service (USFWS) lists three federally protected species for Davidson County. Table 1 lists
the species, their status and biological conclusion.

Tnhle 1 _ Federally-Protected Species for Davidson County. NC
Common Name Scientific Name Federal
Status Habitat
Present Biological Conclusion
Bald eagle Haleaeetus leucephalus Delisted No Not Required
Schweinitz's
sunflower Helianthus schweinitzii E Yes No Effect
Bog turtle Clemmys muhlenbergii T (S/E) N/A Not Required
A Biological Conclusion of "No Effect" was given in the CE for the bald eagle and Schweinitz's
sunflower.
No habitat is present within the study area for the bald eagle. There aze no large bodies of water
present within the study azea to support foraging habitat nor aze there trees large enough to support
an eagle nest. The bald eagle has been delisted as a threatened species as of August 8, 2007.
A field survey for Schweinitz's sunflower was conducted in October 6, 2006 by NCDOT Biologists.
No plants were observed during the 2006 survey. With the above information it is the conclusion of
NCDOT that the original call of "No Effect" is still valid for the Schweinitz's sunflower.
Biological Conclusions are not required for the bog turtle since T (S/A) species are not afforded full
protection under the ESA. No potential habitat occurs within the project azea. No populations of
this species have been reported in the project area. Therefore, the proposed project is not
anticipated to result in an adverse impact to this species.
MITIGATION OPTIONS
Avoidance and Minimization and Compensatory Miti atg_ ion: The NCDOT is committed to
incorporating all reasonable and practicable design features to avoid and minimize jurisdictional
impacts, and to provide full compensatory mitigation of all remaining, unavoidable jurisdictional
impacts. Avoidance measures were taken during the planning and NEPA compliance stages;
minimization measures were incorporated as part of the project design.
According to the Clean Water Act (CWA) §404(b)(1) guidelines, NCDOT must avoid, minimize,
and mitigate, in sequential order, impacts to waters of the US. The following is a list of the
project's jurisdictional stream avoidance/minimization activities proposed or completed by NCDOT:
Avoidance/Minimization:
• Bridge No. 142 will be replaced at its existing location while maintaining traffic with a
temporary structure and detour on the north side. This will minimize construction for the
approaches and lessen impacts to both wetlands and Abbott's Creek.
• In-stream activity will be limited only to the areas shown on the plan sheets.
• A preformed scour hole is to be located on the southwest side of Abbott's Creek.
• Temporary construction impacts due to erosion and sedimentation will be minimized through
implementation of stringent erosion control methods and use of Best Management Practices
(BMPs).
• The onsite detour structure will serve two bridge replacement projects, B-4100 and B-4101.
Compensatory Miti atg ion: The proposed action includes all practicable methods to avoid and/or
minimize jurisdictional stream and buffer impacts that may result from such use. It was determined
3

that there are no practicable alternatives to the proposed construction in jurisdictional waters of the
U.S.
Compensatory mitigation is proposed 0.1-acre of riverine wetland impacts. Compensatory
mitigation will be provided through the EEP. The EEP acceptance letter, dated August 21, 2007, is
attached. No compensatory mitigation is proposed for the 39-feet of stream impacts because the
impacts are for bank stabilization and there will be no loss of aquatic use to Abbott's Creek.
SCHEDULE
The project calls for a letting of January 15, 2008 with a date of availability of February 26, 2008.
Permits are needed by the review date of November 27, 2007. It is expected that the contractor will
choose to start construction as soon as possible.
REGULATORY APPROVALS
Section 404 Permit: The project is being processed by the Federal Highway Administration
as a "Categorical Exclusion" in accordance with 23 CFR 771.115(b). The NCDOT requests
that these activities be authorized by a Nationwide Permit 23 (Federal Register Vol. 72, No.
47 Pages 11092-11198, March l2, 2007). It is anticipated that the temporary impacts will be
authorized under Section 404 Nationwide Permit 33 for the causeway and detour. We are
therefore also requesting the issuance of a Nationwide Permit 33.
Section 401 Permit: We anticipate General Certification numbers 3403 and 3366 will apply to this
project. All general conditions of the Water quality Certifications will be met. Therefore, in
accordance with 15A NCAC 2H, Section .0500(a) and 15A NCAC 2B.0200 we are providing two
copies of this application to the North Carolina Department of Environmental and Natural
Resources, Division of Water Quality, for their notification.
Thank you for your time and assistance with this project. Please contact Sara Easterly at (919) 715-
5499 if you have any questions or need any additional information.

construction to reduce impacts. See cover letter.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation maybe required by the NC Division of Water
Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater
than or equal to 1501inear feet of total impacts to perennial streams.
Page 5 of 8

USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits,
published in the Federal Register on January 15, 2002, mitigation will be required when necessary to
ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of
proposed impact and function and relative value of the impacted aquatic resource will be considered in
determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation
that may be appropriate and practicable include, but are not limited to: reducing the size of the project;
establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as
streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or
preserving similar functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE
or DWQ to consider the application complete for processing. Any application lacking. a required mitigation
plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to
review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in
North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/stnn~ide.html.

associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down
schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or
other issues outside of the applicant's control).

Dear Dr. Thorpe:
Subject: EEP Mitigation Acceptance Letter:
B-4100, Replace Bridge Number 142 on SR 1745 over Abbotts
Creek in Thomasville, Davidson County
The purpose of this letter is to notify you that the Ecosystem Enhancement
Program (EEP) will provide the compensatory riparian wetland mitigation for the subject
project. Based on the information supplied by you on August 7, 2007, the impacts are
located in CU 03040103 of the Yadkin River Basin in the Central Piedmont (CP) Eco-
Region, and are as follows:
Riparian Wetland: 0.10 acre
This mitigation acceptance letter replaces the mitigation acceptance letters
issued on May 14, 2007 and May 29, 2007. EEP understands that the NCDOT no
longer requires off-site stream mitigation for this project. EEP commits to implementing
sufficient compensatory riparian wetland mitigation to offset the impacts associated with
this project by the end of the MOA Year in which this project is permitted, in accordance
with Section X of the Amendment No. 2 to the Memorandum of Agreement between the
North Carolina Department of Environment and Natural Resources, the North Carolina
Department of Transportation, and the U. S. Army Corps of Engineers, fully executed on
March 8, 2007. If the above referenced impact amounts are revised, then this mitigation
acceptance letter will no longer be valid and a new mitigation acceptance letter will be
required from EEP.

03040103); Central Piedmont (CP) Eco-Region
The purpose of this letter is to notify you that the Ecosystem Enhancement Program
(EEP) will provide the compensatory riparian wetland mitigation for the unavoidable impact
associated with the above referenced project. As indicated in the NCDOT's mitigation request

This mitigation acceptance letter replaces the mitigation acceptance letters issued on
May 14, 2007 and May 29, 2007. Compensatory riparian wetland mitigation associated with
this project will be provided in accordance with Section X of the Amendment No. 2 to the
Memorandum of Agreement between the N. C. Department of Environment and Natural
Resources, the N. C. Department of Transportation, and the U. S. Army Corps of Engineers fully
executed on March 8, 2007 (Tri-Party MOA). EEP commits to implement sufficient
compensatory riparian wetland mitigation up to 0.20 riparian wetland credits to offset the impacts
associated with this project by the end of the MOA year in which this project is permitted. 1f the
above referenced impact amounts are revised, then this mitigation acceptance letter will no longer
be valid and a new mitigation acceptance letter will be required from EEP.
If you have any questions or need additional information, please contact Ms. Beth
Harmon at 919-715-1929.

State Project No. WBS 33456.1.1
T.I.P. No. B-4100
M INTRODUCTION: The replacement of Bridge No. 142 is included in the North Carolina
Department of Transportation 2004-2010 Transportation Improvement Program and in the
Federal-Aid Bridge Replacement Program. The location is shown in Figure lA. No substantial
environmental impacts aze anticipated. The project is classified as a Federal "Categorical
Exclusion".
I. PURPOSE AND NEED STATEMENT
Bridge Maintenance Unit records indicated the bridge has a sufficiency rating of 34.6 out of a
possible 100 for a new structure. The bridge is considered functionally obsolete and structurally
deficient. The replacement of this inadequate structure will result in safer and more efficient
traffic operations.
II. EXISTING CONDITIONS
SR 1741 (Walburg-High Point Road) crosses over Abbott's Creek at the northeast comer of
Davidson County approximately 0.7 mile east of its junction with SR 1743 (Abbott's Creek
Church Road) and approximately 0.6 mile west of its junction with SR 1735 (Curry Road).
Development in the proximity is low density residential and agricultural. Meadows and
cultivated fields are located in all four quadrants. SR 1741 is classified as an Urban Minor
Arterial in the Statewide Functional Classification System.
SR 1741 has a current pavement width of 20 feet with 6-foot grass shoulders in the area of the
bridge. The bridge is located on tangent between two horizontal curves and two vertical sag
curves. Vertical and horizontal alignments of the roadway approaches aze good. The east
approach curves to the right and is on a slight upgrade. Sight distance is good both to the west
and to the east of the bridge.
The 2005 estimated traffic volumes on SR 1741 at Abbott's Creek are 4200 vehicles per day
(vpd) and for the design year 2025 the estimated traffic volumes are 6600 vpd. The speed.limit
is 55 mph in the vicinity of the bridge.
1

Bridge No. 142, as shown in Figures 2A and 2B, has an overall length of 106 feet and a cleaz
deck width of 24 feet. The existing two-lane bridge has a reinforced concrete deck on I-beams
supported by reinforced concrete caps and timber piles at approximate 35-foot centers. The
structure was constructed in 1949. The current posted weight limit is 28 tons for single unit
vehicles and 34 tons for truck-tractor semi-trailer vehicles. A relatively large number of dump
trucks were observed during field trip visits in October 2003. The bridge has a sufficiency rating
of 34.6 compared to a rating of 100 for a new structure. Bridge No. 142 has abed-to-crown
distance of approximately 16 feet.
One accident was reported in the vicinity of the bridge during the period from April 1, 1999 to
March 31, 2002. The accident rate is 114.05 accidents per 100 million vehicle miles (MVM).
The statewide average accident rate for rural secondary routes (two lanes undivided) for the
three-yeaz period 2000-2002 is 347.58 accidents per 100 MVM.
There are aerial telephone cables along the north side of SR 1741 crossing over Abbott's Creek,
and underground telephone cables along north side of SR 1741. No power lines are in the
existing bridge vicinity. A water main is located along the south side of SR 1741. There are no
utilities attached to the bridge. Utility conflicts are considered low.
Public school buses cross the existing bridge 14 times per day.
III. ALTERNATIVES
A. Project Description
NCDOT proposes to replace Bridge No. 142 with a new bridge approximately 130 feet long with
a maximum cleaz roadway width of 40 feet. The final bridge length will be determined during
fmal bridge design. New approaches to the bridge will provide 12-foot travel lanes in each
direction with 8-foot shoulders [2-foot paved]. The proposed typical sections are shown in
Figure 3A.
B. Detailed Study Alternatives
The studied alternatives were: (1) Replacing Bridge No. 142 at its existing location while
maintaining traffic with a temporary structure and detour on the north side; and (2) Replacing
Bridge No. 142 on the north side while maintaining traffic on the existing structure as an onsite
detour. Alternatives 1 and 2 are shown in Figures 4 and 5. The posted speed limit is 55 mph and
the corresponding design speed is 60 mph.
2

Replacing Bridge No. 142 with a new bridge in the existing location, closing SR 1741 to through
traffic during construction and utilizing an offsite detour was investigated. The possible offsite
detour route (Figure 6) includes SR 1743 (Abbotts Creek Church Road) and SR 1756 (Old
Greensboro Road). The detour is approximately 5.3 miles in length.
- In accordance with the NCDOT Guidelines for Evaluation of Offsite Detours for Bridge
Replacement Projects (April 2004), the average delay per motorist using the offsite detour is
• estimated to range from 5-7 minutes for a construction period of 12 months, which falls under
the Evaluation (E) range of the Guidelines. The Evaluation (E) range suggests that an onsite
detour is justifiable from a traffic operations standpoint but must be weighed with other project
factors to determine if it is appropriate. The TIMS Coordinator requests an acceptable bus
turnaround if the offsite detour is to be utilized. Coordination with the Homey Town Fire
Department indicates that road closure would cause problems due to lack of suitable detour.
Based on these concerns the offsite detour is not considered appropriate.
C. Alternatives Eliminated from Further Study
The No-Build or "do-nothing" alternative was also considered but this alternative would
eventually necessitate closure of the bridge. This is not a desirable alternative due to the traffic
service provided by SR 1741.
Investigation of the existing structure by the NCDOT Bridge Maintenance Unit indicates that
rehabilitation of Bridge No. 142 is not feasible due to its age and deteriorated condition. The
existing bridge is classified as structurally deficient.
Replacing the bridge in its existing location and maintaining traffic with an off site detour was
eliminated from further consideration because (1) local Fire Department expressed concerns with
their ability to serve the area, (2) school bus route disruptions (14 bus crossings per day), (3) on
both field trips to the bridge area a significant number of construction trucks were observed
using SR 1741, and (4) according to NCDOT Guidelines for Evaluation of Offsite Detours for
- Bridge Replacement Projects, the expected delay per motorist of 5-7 minutes was beyond the
acceptable range.
An alternative to replace the bridge on the south side of the existing bridge was not considered.
Due to the geometry of the existing roadway, double reverse curves would be required at both
approaches for a southern alternative. Also, this alternative was not studied because of stream
impacts.
3

D. Preferred Alternative
Alternate 1, replacing Bridge No. 142 at its existing location while maintaining traffic with a
temporary structure and detour on the north side, is the preferred alternative. Alternate 1 was
selected to keep the new bridge in the same location as the existing, because it minimizes
construction for the approaches, and it lessens the impacts to adjacent properties.
The new structure will be approximately 130 feet long with a maximum clear roadway width of
40 feet. New approaches to the bridge will provide 12-foot travel lanes with 8-foot shoulders
including 2-foot paved shoulders. Approximately 2100 feet of new approaches will be required.
The design speed of the replacement structure will be 60 mph; however, a design exception for
the vertical alignment will be necessary. The design exception for the vertical curve with a
design speed of 50 mph is required because maintaining a 60 mph design speed will necessitate a
longer vertical curve and raising the grade considerably. A longer vertical curve and grade
change may impact adjacent residences and will increase the estimated cost of this alternate.
The estimated cost for the recommended proposed improvement is $1,795,000. The current
estimated cost of the project, as shown in the NCDOT 2004-2010 Transportation Improvement
Program, is $ 80,000 for right-of--way and $775,000 for construction.
The Division Office concurs with the recommended unprovements.
IV. ESTIMATED COST
The estimated costs of the alternatives studied, based on 2004 prices, are shown in the following
table:
Alternate 1
Onsite Detour Alternate 2
New Location
Structure Removal $ 21,840.00 $ 21,840.00
Structure $ 402,480.00 $ 448,920.00
Roadway Approaches $ 222,540.00 $ 524,810.00
Mobilization and Miscellaneous $ 164,140.00 $ 306,430.00
Engineering and Contingencies $ 139,000.00 $ 198,000.00
Temporary Detour $ 700,000.00 N/A
SUBTOTAL $ 1,650,000.00 $ 1,500,000.00
Right-of-Way/Const./Util. $ 145,000.00 $ 238,500.00
TOTAL $ 1,795,000.00 $1,738,500.00
4

The above estimates are based on functional design plans; therefore, 45 percent is included for
miscellaneous items and contractor mobilization, and 15 percent for engineering and
contingencies.
V. NATURAL RESOURCES
A. Methodology
Materials and literature supporting this investigation have been derived from a number of
sources including U.S. Geological Survey (tJSGS) topographic mapping (High Point West, NC
(1993) 7.5-minute quadrangle), U.S. Fish and Wildlife Service National Wetlands Inventory
(NWI) mapping (High Point West, NC (1993) 7.5-minute quadrangle), Natural Resources
Conservation Service (NRCS; formerly the Soils Conservation Service) soils mapping (SCS
1994), WRC proposed Significant Aquatic Endangered Species Habitats (WRC 1998), and
recent aerial photography.
Plant community descriptions aze based on a classification system utilized by the NC 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) with adjustments for updated nomenclature (Kartesz
1998). Jurisdictional areas were evaluated using the three-parameter approach following U.S.
Army Corps of Engineers (USAGE) delineation guidelines (DOA 1987). Jurisdictional areas
were chazacterized according to a classification scheme established by Cowazdin et al. (1979)
and/or the NC Division of Environmental Management (DEM) Field Guide to North Carolina
Wetlands (1996). Aquatic and terrestrial wildlife habitat requirements and distributions were
determined by supportive literature (Martof et al. 1980, Potter et al. 1980, Webster et al. 1985,
Menhinick 1991, Palmer and Braswell 1995, and Rohde et al. 1994). Water quality information
for area streams and tributaries was derived from available sources (DWQ 2002, DWQ 2004a-c).
Quantitative sampling was not undertaken to support existing data.
The most current FWS listing of federally protected species with ranges extending into Davidson
County (February 11, 2003 FWS list) is considered in this report. In addition, NHP records
documenting the presence of federally or state listed species were consulted on April 17, 2004
before commencing field investigations. In addition, Significant Aquatic Endangered Species
Habitats proposed by the WRC (December 11, 1998 listing) were consulted to determine the
presence of Proposed Critical Habitats for aquatic species.

The project study area is located at the crossing of Walburg-High Point Road over Abbott's
Creek approximately 2.5 miles west of High Point, NC. Abbott's Creek flows to the south
through the project study area, which is oriented along aneast-west axis. The project study
boundary is about 300 feet in width (centered on the existing roadway) and about 2775 feet in
length, encompassing approximately 19.5 acres. The project study azea was walked and visually
surveyed for significant features. Potential impacts of construction will be limited to cut-fill
boundaries for each alternative. Special concerns evaluated in the field include 1) potential
protected species habitat and 2) wetlands and water quality protection of Abbott's Creek.
B. Physiography and Soils
The project study azea is located within the Southern Outer Piedmont ecoregion of the Piedmont
physiographic province of North Carolina. This ecoregion is chazacterized by dissected irregular
plains, some low rounded hills and ridges; and low to moderate gradient streams with mostly
cobble, gravel, and sandy substrates (Griffith et al. 2002). The project study azea is located
within a moderately sloping floodplain valley. Elevations within the project study area range
from a high of approximately 850 feet National Geodetic Vertical Datum (NGVD) at the eastern
end of the project study azea, to a low of approximately 775 feet NGVD within the stream
channel (High Point West, NC (1993) 7.5-minute quadrangle). Land uses within and adjacent to
the project study area consist of woodlands, agricultwe, residential lots, powerline corridors, and
roadside shoulders.
Based on soil mapping for Davidson County (SCS 1994), the project study area is underlain by
six soil series: Cecil sandy loam (Typic Kanhapludults), Chewacla loam (Fluvaquentic
Dystrochrepts), Enon fine sandy loams (Ultic Hapludalfs), Poindexter sandy loams (Typic
Hapludalfs), Zion sandy loams (Ultic Hapludalfs), and Vance sandy loam (Typic Hapludults).
Chewacla loam occurs adjacent to the stream, and the remainder are found on the slopes.
Poindexter and Zion fine sandy foams are intricately mixed within Davidson County. Chewacla
loam is considered non-hydric with hydric inclusions in Davidson County (NRCS 1997), and
underlies approximately 8.0 acres, or 41 percent of the project study area.
The Cecil series (2 to 8 percent slopes) consists of well-drained sandy loam on smooth upland
ridges with moderate permeability. Erosion of this soil is a moderate hazard when the soil
surface is bare and unprotected. Depth to bedrock is greater than 60 inches, and the seasonal
high water table occurs at a depth greater than 6 feet.
The Chewacla series (0 to 2 percent slopes) consists of poorly drained soil in floodplains that
was formed in recent alluvium. This soil tends to be flooded frequently. Permeability of this
6

soil is moderate, depth to bedrock is greater than 5 feet, and the seasonal high water table occurs
between 0.5 and 1.5 feet.
The Enon series consists of well-drained fine sandy loam on upland ridges. Permeability of this
soil is slow, and erosion is a moderate to severe hazard when the soil surface is bare and
unprotected. Depth to bedrock is greater than 60 inches, and the seasonal high water table occurs
at a depth greater than 6 feet.
The Poindexter series consists of well-drained fine sandy loams intermixed with Zion fine sandy
loams on upland ridges and side slopes. Permeability of this soil is moderate, and, due to the
slope and surface runoff, erosion is a moderate to severe hazard when the soil surface is haze
and unprotected. Depth to bedrock occurs between 20 and 40 inches, and the seasonal high
water table occurs at a depth greater than 6 feet.
The Vance series with 2 to 8 percent slopes consists of deep, well-drained sandy loam on narrow,
upland ridges. Permeability of this soil is slow, and erosion is a severe hazard when the soil
surface is baze and unprotected. Depth to bedrock is greater than 60 inches, and the seasonal
high water table occurs at a depth greater than 6 feet.
The Zion series with consists of well-drained fine sandy loams intermixed with Poindexter fine
sandy loams on upland ridges and side slopes. Permeability of this soil is slow to moderately
slow, and erosion is a moderate to severe hazard when the soil surface is baze and unprotected.
Depth to bedrock occurs between 20 and 40 inches, and the seasonal high water table occurs at a
depth greater than 6 feet.
C. Water Resources
1. Waters Impacted
The project azea is located within sub-basin 03-07-07 of the Yadkin River Basin (DWQ 2002).
. This azea is part of USGS Hydrologic Unit 03040103 of the South Atlantic/Gulf Region. The
portion of Abbott's Creek that lies within the project area has been assigned Stream Index
Number 12-119-(1) by DWQ (DWQ 2004a).
2. Water Resources Characteristics
The project area contains two streams: Abbott's Creek and one unnamed tributary (UT) to
Abbott's Creek. Abbott's Creek generally flows southward through the middle of the project
area. The UT is located in the southeastern quadrant formed by the intersection of WaIburg-
High Point Road and Abbott's Creek. The UT flows northward into the project area, turning
7

west at the toe of the maintained right-of--way slope and continuing approximately 400 feet to a
confluence with Abbott's Creek approximately 40 feet south of the existing bridge (Figure 7).
The UT has not been assigned a SIN by DWQ.
Abbott's Creek enters the project azea as awell-defined, third-order, perennial stream with
moderate flow over a cobble, gravel, and sand substrate (containing some boulders). At Bridge
No. 142, Abbott's Creek is approximately 30 feet wide with banks of approximately 7 feet.
Moving away from the bridge, the banks of Abbott's creek range from 2 to 7 feet and are steeply
sloping. During field investigations, the water level appeazed low and ranged to approximately
1.5 feet deep. Water clarity was good, with visibility to the substrate, and flow velocity was
moderate. No persistent emergent aquatic vegetation was observed within the stream. Abbott's
Creek may provide good aquatic habitat for mussels and benthic macroinvertebrates due to the
observation of little siltation within the stream and the channel substrate composition.
Opportunities for habitat within Abbott's Creek include overhanging trees, undercut banks, and
leaf packs.
The UT enters the project area as awell-defined, first-order, perennial stream with slow flow
over a fine sand and silt substrate. The steeply sloping banks of the UT range from
approximately 2 feet high as it enters the project area to approximately 5 feet at the confluence of
Abbott's Creek. During field investigations, the water level appeared low and ranged to
approximately 6 inches in depth. Water clarity was good, with visibility to the substrate, and
flow velocity was slow. No persistent emergent aquatic vegetation was observed within the
stream. Opportunities for habitat within the UT include overhanging trees, undercut banks, and
leaf packs.
The DWQ has assembled a list of impaired waterbodies according to the Clean Water Act
Section 303(d) and 40 CFR 130.7, hereafter referred to as the N.C. 2004 Section 303(d) list
(DWQ 2004c). The list is a comprehensive public accounting of all impaired waterbodies. An
impaired waterbody is one that does not meet water quality standards including designated uses,
numeric and narrative criteria, and anti-degradation requirements defimed in 40 CFR 131. The
standazds violation may be due to an individual pollutant, multiple pollutants, pollution, or an
unknown cause of impairment. The impairment could be from point sources, nonpoint sources,
and/or atmospheric deposition. Some sources of impairment exist across state lines. North
Carolina's methodology is strongly based on the aquatic life use support guidelines available in
the Section 305(b) guidelines (EPA-841-B-97-002A and -002B). Those streams attaining only
Partially Supporting (PS) or Not Supporting (NS) status are listed on the N.C. 2004 Section
303(d) list. Streams are further categorized into one of six parts within the N.C. 2004 Section
303(d) list, according to source of impairment and degree of rehabilitation required for the
stream to adequately support aquatic life. Within Parts 1, 4, 5, and 6 of the list, North Carolina
8

has developed a priority ranking scheme (low, medium, high) that reflects the relative value and
benefits those waterbodies provide to the State. The reach of Abbott's Creek between U.S.
Highways 29/70 and the Abbott's Creek. Arm of High Rock Lake is on the N.C. 2004 Section
303(d) list due to impaired biological integrity (DWQ 2004c). This 8.0 mile reach of Abbott's
Creek lies approximately 18 stream miles downstream of the project azea. The reach of Abbott's
Creek within the project area is not listed on any section of the N.C. 2004 Section 303(d) list.
Classifications are assigned to waters of the State of North Cazolina based on the existing or
contemplated best usage of various streams or segments of streams in the basin. A Best Usage
Classification of WS-III has been assigned to this reach of Abbott's Creek and its unnamed
tributaries. Class WS-III waters are protected as water supplies which are generally in low to
moderately developed watersheds, and are suitable for all class C uses. Class C waters aze
suitable for aquatic life propagation and protection, agriculture, and secondary recreation.
Secondary recreation includes wading, boating, and other uses not involving human body contact
with waters on an organized or frequent basis. No designated High Quality Waters (HQW),
Outstanding Resource Waters (ORW), Water Supply I (WS-I), Water Supply II (WS-II) waters,
or watershed Critical Areas (CA) occur within 1.0 mile of the project area (DWQ 2002).
Pursuant to the NCDWQ Red Book (15 A NCAC 02B.0100 and .0200, August 1, 2004),
vegetative buffers aze required for all new development along all WS-III and WS-IV perennial
waters indicated on the most recent versions of USGS 7.5-minute topographic mapping. The
buffer width is determined by the development density option chosen by local governments. A
minimum 100-foot vegetative buffer is required for non-residential development activities that
exceed the low-density option; otherwise, a 30-foot buffer is required and stormwater runoff
must be transported by vegetated conveyances to the maximum extent practicable. Public road
projects may be allowed within the buffer where no practicable alternative exists, as long as
built-upon -azea is minimized, runoff is directed away from surface waters, and the use of Best
Management Practices (BMPs) is maximized.
The Division of Water Quality (DWQ) has initiated awhole-basin approach to water quality
management for the 17 river basins within the state. Water quality for the proposed project azea
is summarized in the Yadkin River Basinwide Water Quality Plan (DWQ 2002). Abbott's Creek
is currently listed by DWQ as Supporting its designated uses. No benthic macroinvertebrate
monitoring stations occur within one mile of the project azea (DWQ 2002).
Sub-basin 03-07-07 of the Yadkin River Basin supports 13 permitted, point source discharges
with a total discharge of over 15.8 million gallons per day. Three of the permitted discharges are
classified as major dischazgers, discharging 15.7 million gallons per day. The 10 remaining
permitted dischargers are minor, with one having no limits set on discharges (DWQ 2004b).
9

One discharger, Lakeview Mobile Home Park (permit number N00051713) discharges into
Cuddybum Creek (SIN 12-119-2), which comes to a confluence with Abbott's Creek
approximately 2.0 miles upstream from the project study area. Lakeview Mobile Home Park is
located approximately 2.5 miles upstream from the project study area, and is listed as a minor
discharger with a flow of 15000 gallons per day (DWQ 2004b). Cuddybum Creek has been
assigned a Best Usage Classification of WS-III and does not appeaz on any section of the NC
2004 303d list (DWQ 2004c). Major non-point sources of pollution within the Yadkin Basin
include runoff from construction activities, agriculture, timber harvesting, hydrologic
modification, failing septic systems, roads, pazking lots, and roof tops. Sedimentation and
nutrient inputs are major problems associated with non-point source discharges (DWQ 2002).
The North Carolina Wildlife Resources Commission (NCWRC) has developed a Significant
Aquatic Endangered Species Habitat database to enhance planning and impact analysis in areas
proposed by WRC as being critical due to the presence of Endangered or Threatened aquatic
species. No Significant Aquatic Endangered Species Habitat occurs within the project azea. The
nearest Significant Aquatic Endangered Species Habitat within the Yadkin River Basin occurs
approximately 5.8 miles to the southeast (NCWRC 1998).
3. Anticipated Impacts to Water Resources
a) GeneralImpacts
Impacts to water resources in the project area may result from activities associated with project
construction. Activities that would result in impacts are clearing and grubbing on streambanks,
riparian canopy removal, in-stream construction, fertilizers and pesticides used in revegetation,
and pavement/culvert installation. The following impacts to surface water resources could result
from the construction activities mentioned above.
• Increased sedimentation and siltation downstream of the crossing and increased
erosion in the project area.
• Alteration of stream discharge due to silt loading and changes in surface and
groundwater drainage patterns.
• Changes in light incidence and water clarity due to increased sedimentation and
vegetation removal.
• Changes in and destabilization of water temperature due to vegetation removal.
• .Alteration of water levels and flows due to interruptions and/or additions to
surface and ground water flow from construction.
• Increased nutrient loading during construction via runoff from exposed areas.
10

• Increased concentrations of toxic compounds in roadway runoff.
• Increased potential for release of toxic compounds such as fuel and oil from
construction equipment and other vehicles.
• The proposed bridge replacement will allow for continuation of pre-project stream flows in
Abbott's Creek, thereby protecting the integrity of this waterway. Long-term impacts resulting
from construction aze expected to be negligible. In order to minimize impacts to water
resources, NCDOT's Best Management Practices for the Protection of Surface Waters will be
strictly enforced during the entire life of the project.
Temporary construction impacts due to erosion and sedimentation will be minimized through
implementation of a stringent erosion-control schedule and the use of Best Management
Practices (BMPs). The contractor will follow contract specifications pertaining to erosion
control measures as outlined in 23 CFR 650 Subpart B and Article 107-13 entitled Control of
Erosion, Siltation, and Pollution (NCDOT, Specifications for Roads and Structures). These
measures include the use of dikes, berms, silt basins, and other containment measures to control
runoff; elimination of construction staging areas in floodplains and adjacent to waterways; re-
seeding of herbaceous cover on disturbed sites; management of chemicals (herbicides, pesticides,
de-icing compounds) with potential negative impacts on water quality; and avoidance of direct
dischazges into steams by catch basins and roadside vegetation.
b) .Impacts Related to Bridge Demolition and Removal
The existing two-lane bridge has a reinforced concrete deck on I-beams supported by reinforced
concrete caps and timber piles. The structure is .expected to be removed without dropping
components into Abbott's Creek.
D. BIOTIC RESOURCES
1. Plant Communities
Three distinct plant communities were identified within the project azea: disturbed/maintained
land, mixed pine/hazdwood forest, and alluvial forest. Plant communities were delineated to
determine the approximate area and location of each (Figure 7). These communities aze
described below in order of their dominance within the project area.
11

a) Disturbed/maintained land
Approximately 13.2 acres (68 percent) of the project study area is encompassed by
disturbed/maintained land. This community dominates the western half of the project study area,
and comprises approximately one half of the eastern portion of the project study area.
Disturbed/maintained land includes roadside shoulders, pasture, agricultural fields, utility line
corridors, and residential lots. In pastures and along roadside shoulders and agricultural land
margins, grasses and herbs dominate the vegetation. Representative species include Carolina
cranesbill (Geranium carolinianum), lyre-leafed sage (Salvia lyrata), white. clover (Trifolium
repens), red clover (Trifolium pratense), bachelor's button (Centaurea cyanus), common
buttercup (Ranunculus bulbosus), vetch (Vicia sp.), fescue (Festuca sp.), and dandelion
(Taraxacum off cinale).
Along woodland edges, utility line corridors, and slopes adjacent to the maintained road right-of-
way, the sapling/shrub layer is dominated by multiflora rosa (Rosa multiflora), with scattered
individuals of sweetgum (Liguidambar styraciflua), tulip poplaz (Liriodendron tulipifera), black
cherry (Prunus serotina), river birch (Betula nigra), and red maple (Ater rubrum). Vines present
include Japanese honeysuckle (Lonicera japonica) and muscadine grape (Vitis rotundifolia).
Representative herbs include evening primrose (Oenothera biennis), ebony spleenwort
(Asplenium platyneuron), periwinkle (Vinca minor), and bluet (Houstonia caerulea).
Two wet areas dominated by grasses and herbs are located within the disturbed portion of the
project area (Figure 7, Sites 1-2). These areas appear to have been excavated in order to lower
the water table within the Abbott's Creek floodplain. These linear depressions were
systematically excavated across the floodplain, and are interconnected in such a fashion to move
surface water and surficial ground water from the floodplain into Abbott's Creek. These
depressions aze characterized by no evidence of flow and support hydrophytic vegetation such as
spikerush (Eleocharis sp.), duckweed (Lemna sp.), soft rush (Juncus effusus), and tag alder
(Alnus serrulata).
b) Mixed Pine/Hardwood Forest
Approximately 4.4 acres (23 percent) of the project study azea is encompassed by mixed
pine/hazdwood forest. This community occurs on uplands in the project study area.
Approximately one half of the eastern portion of the project study. area is comprised of this
community. A small area of mixed pine/hazdwood forest also extends into the southwestern
quadrant formed by the intersection of Abbott's Creek and Walburg-High Point Road. This
community consists of a mature forest characterized by a closed canopy with a relatively dense
understory.
12

In this community, the canopy is made up of red maple, sweetgum, black oak (Quercus velutina),
loblolly pine (Pinus taeda), and shortleaf pine (Pinus echinata). The subcanopy/shrub layers
include saplings of canopy species, flowering dogwood (Corpus jlorida), multiflora rose, eastern
red cedar (Juniperus virginiana), and sourwood (Oxydendrum arboreum). Vines include
common greenbrier (Smilax rotundifolia), Japanese honeysuckle, trumpet honeysuckle (Lonicera
- sempervirens), and Virginia creeper (Parthenocissus quinquefolia). Representative species of
herbs include ebony spleenwort and poison ivy (Toxicodendron radicans).
c) Alluvial Forest
Approximately 0.5 acre (3 percent) of the project area is encompassed by alluvial forest. This
community occurs within the floodplain of Abbott's Creek. This community consists of a
mature forest characterized by a closed canopy with a relatively open understory. Canopy species
include red maple, river birch, black willow (salix nigra), sweetgum, and American elm (Ulmus
americana). The sapling/shrub layer consists of canopy species as well as box elder (Ater
negundo) and multiflora rose. Herb species consist of tearthumb (Polygonum sagittatum),
poison ivy, and jewelweed (Impatiens capensis), while vines present consist of common
greenbrier and Japanese honeysuckle.
2. Wildlife
Wildlife duectly observed in a plant community or determined to be present through evidence
(tracks, scat, burrows, etc.) during field investigations are indicated with an asterisk (*). In
addition, approximately 1.3 acres (7 percent) of the project study area is covered by the
impermeable surface of Walburg-High Point Road.
Disturbed/maintained land
Wildlife which may occur within the open portion of the project study azea include vegetation
and seed eaters such as eastern harvest mouse (Reithrodontomys humulis), meadow vole
(Microtus pennsylvanicus), hispid cotton rat (Sigmodon hispidus), and American goldfinch
(Carduelis tristis); insectivores such as eastern mole (Scalopus aquaticus), least shrew (Cryptotis
parva), red bat (Lasiurus borealis), killdeer (Charadrius vociferous), southeastern five-lined
skink (Eumeces inexpectatus), and American toad (Bufo americanus); predators of small
mammals, birds, and herptiles such as red fox (Vulpes vulpes), red-tailed hawk* (Buteo
jamaicensis), American kestrel, and garter snake (Thamnophis sirtalis); and scavengers such as
Virginia opossum (Didelphis virginiana), American crow* (Corvus brachyrhynchos), and turkey
vulture (Cathartes aura).
Ecotones provide both food and cover for eastern cottontail (Sylvilagus floridanus) and white-
tailed deer (Odocoileus virginianus). Birds commonly found in shrubby areas and along
13

forest/grassland ecotones include the omnivorous northern mockingbird (Mimus polyglottos),
brown thrasher (Toxostoma rufum), and brown-headed cowbird* (Molothrus ater), and the seed-
eating indigo bunting* (Passerina cyanea). Insectivorous species such as eastern fence lizard
(Sceloporus undulatus) and gray treefrog (Hyla chrysoscelis), and predators including black
racer (Coluber constrictor), utilize this habitat.
During the field visit, a mallazd* (Anas platyrhynchos) was observed within one of these
depressions. Herptiles expected in marshy azeas such as these include spring peeper (Pseudacris
crucifer), northern cricket frog (Acris crepitans), and northern water snake (Nerodia sipedon).
Mixed Pine/Hazdwood Forest
The complexity and size of this community allow for a diverse assemblage of wildlife including
forest interior species. This community should support predators such as grey fox (Urocyon
cinereoargenteus), screech owl (Otus asio), sharp-shinned hawk (Accipiter striatus), copperhead
(Agkistrodon contortrix), black rat snake (Elaphe obsoleta), and ringneck snake (Diadophis
punctatus); herbivores such as gray squirrel (Sciurus carolinensis), southern flying squirrel
(Glaucomys volans), white-footed mouse (Peromyscus leucopus), eastern cottontail, northern
cazdinal* (Cardinalis cardinalis), and eastern box turtle (Terrapene Carolina); and insectivores
such as pine warbler (Dendroica pinus), wood thrush (Hylocichla mustelina), golden-crowned
kinglet (Regulus satrapa), Cazolina wren (Thryothorus ludovicianus), red-eyed vireo (Vireo
olivaceous), northern fence lizazd (Sceloporus undulatus), five-lined skink (Eumeces fasciatus),
and slimy salamander (Plethodon glutinosus).
Alluvial Forest
This relatively narrow community extends through the project study area along both sides of
Abbott's Creek and provides food and cover and a travel corridor for wildlife within this riparian
habitat. Species utilizing alluvial forest in this portion of the state include- predators such as
barred owl (Strix varia) and northern water snake; scavenging omnivores such as raccoon*
(Procyon lotor); seed, vegetation, and insect eaters such as northern cazdinal*, eastern phoebe*
(Sayornis phoebe), summer tanager* (Piranga rubra), wood thrush (Hylocichla mustelina),
golden-crowned kinglet, Cazolina wren (Thryothorus ludovicianus), red-eyed vireo, gray
squirrel, and red bat.
Many of these wildlife species aze adaptable and can eat a wide variety of plant and animal
material when the preferred food is absent. Many of these species can be found within disturbed
areas, brushy edges of the forest, within heavy underbrush, or amongst shrubby plants.
Migration between communities of the project area may be frequent based on the needs of each
species for food, cover, protection from predators, and nesting.
14

3. Aquatic Communities
The project study area includes two perennial streams, all bounded by natural vegetation. These
streams are characterized by natural channels providing diverse habitats for fish and wildlife
(riffle-pool complexes, undercut banks, rock and organic debris in the stream beds, and
• overhanging branches. These waters are expected to support a fishery and benthic population
which serves as a food source for aquatic herptiles such as northern water snake, bullfrog* (Rana
catasbeina), green frog (Rana clamitans), eastern musk turtle (Sternotherus odoratus), and two-
lined salamander (Eurycea bislineata).
No sampling was undertaken in Abbott's Creek to determine fishery potential and no fish species
were observed during the field survey. Fish species that may be present in this reach of Abbott's
Creek include smaller fish species such as creek chub (Semotilus atromaculatus), margined
madtom (Noturus insignis), rosyside dace (Clinostomus funduloides), and spottail shiner
(Notropis hudsonius).
4. Summary of Anticipated Impacts
Permanent and temporary impacts are anticipated as a result of this project. Permanent impacts
aze considered to be those impacts that occur within proposed cut-fill limits. Temporary impacts
aze considered to be those impacts which occur within the cut-fill footprint associated with the
temporary detour of Alternate 1. Plant communities within the project study area were
delineated to determine the approximate area and location of each (Figure 7). A summary of
plant community areas and the potential impacts to each is presented in Table 1.
Table 1. Plant Communities Within Cut/Fill lines of Respective Alternatives

Alluvial Forest -- 0.04 0.04 0.05
Total 1.57 1.86 3.43 3.27
• rueas are given m acres.
While total impacts to plant communities are roughly the same for both alternatives, permanent
impacts resulting from the construction of Alternate 1 are approximately one half of the area
permanently impacted by Alternate 2. In addition, construction of the temporary structure
15

associated with Alternative 1 will require approximately 0.04 acre of alluvial forest to be logged.
Likewise, the new structure associated with Alternative 2 will require the removal of
approximately 0.05 acre of alluvial forest.
Projected permanent impacts to natural plant communities resulting from bridge replacements
are generally restricted to narrow strips adjacent to the existing bridge and roadway approach
segments. Little area of natural plant community is expected to be permanently impacted by the
proposed project. Temporary impacts present the greater amount of impact to natural
communities, and although these impacts are considered to be short-term, re-growth of this
community to pre-project stand age and ecological function will require.several decades.
No significant habitat fragmentation is expected as a result of project activities since potential
improvements will be restricted to adjoining roadside margins. Construction noise and
associated disturbances are anticipated to have short-term impacts on avifauna and migratory
wildlife movement patterns.
No Significant Aquatic Endangered Species Habitat exists within or near the project study area
(WRC 1998). Impacts associated with turbidity and suspended sediments resulting from bridge
replacement will be minimized through stringent erosion control measures.
Potential downstream impacts to aquatic habitat are anticipated to be avoided by bridging the
stream system to maintain regular flow and stream integrity. Short-term impacts associated with
turbidity and suspended sediments may affect benthic populations. Temporary impacts to
downstream habitat from increased sediment during construction will be minimized by the
implementation of stringent erosion control measures. After bridge construction, temporary
detour structures and approaches will be removed and the area reseeded.
E. JURISDICTIONAL TOPICS
1. Waters of tLe United States
Surface waters within the project area are subject to jurisdictional consideration under Section
404 of the Clean Water Act as waters of the United States (33 CFR Section 328.3). The National
Wetlands Inventory (NWI) system for classification of wetlands and deepwater habitats was used
to determine the type of each wetland present (Cowardin et al. 1979). Section 404 jurisdictional
areas are depicted by Figure 7.
16

Abbott's Creek exhibits characteristics of awell-defined, third-order, perennial stream with
moderate flow over a gravel and sand substrate with some boulders. This stream contains
several unvegetated point bazs composed of sand and gravel. Abbott's Creek can be classified as
riverine, upper perennial with an unconsolidated bottom composed primarily of gravel and sand
(RiUB 1). The UT can be classified as awell-defined, first-order, riverine, lower perennial
stream with an unconsolidated bottom composed primarily of sand and silt (R2UB2).
Vegetated ,wetlands 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). The project study azea contains two vegetated
wetland areas (Figure 7, Wetlands 1 and 2).
A grass and herb dominated series of associated wetland, linear depressions is located in the
northwest quadrant of the project study azea, and drains the associated pasture land (Figure 7,
Wetland 1). This wetland azea includes a seepage slope on the outer edge of the floodplain and
linear depressions excavated to drain a floodplain for use as pasture. This wetland azea may be
classified as palustrine, persistently emergent, and permanently flooded (PEM1H). Soils exhibit
hydric chromas, and support hydrophytic vegetation such as spikerush and duckweed. Standing
water is clear with light surface flow in places. ,Hydrology indicators include inundation,
drainage patterns, and oxidized rhizospheres. This system would be considered a "riverine"
wetland by DWQ, based upon its location within the Abbott's Creek floodplain.
A grass and herb dominated series of associated wetland, linear depressions is located in the
northeast quadrant of the project study azea, and drains the adjacent agricultural field (Figure 7,
Wetland 2). This field, fallow this season, but most recently used to grow corn, appears to have
been trenched in order to lower the water table. Similaz to Wetland 1, Wetland 2 includes a
seepage azea on the outer edge of the floodplain. This wetland area exhibits hydrophytic
vegetation such as spikerush, soft rush, and tag alder and may be classified as palustrine,
persistently emergent, and seasonally flooded (PEM1C). Standing water is murky and shows
little evidence of movement. Soils exhibit hydric chromas and hydrology indicators include
- inundation, light surface flow, and oxidized rhizospheres. This system would be considered a
"riverine" wetland by DWQ, based upon its location within the Abbott's Creek floodplain.
Both alternatives will result in impacts to both Wetlands 1 and 2. Implementation of Alternate 1
will also result in temporary impacts to both wetlands. No temporary impacts aze anticipated to
result from Alternate 2 construction. No temporary or permanent impacts associated with either
alternative aze projected to result in direct impacts to surface waters. A summary of potential
jurisdictional azea impacts is summarized in Table 2.
17

Table 2. Projected Impacts to Jurisdictional Wetland Areas
(Wetlands are depicted on Figure 7. Area is expressed in acres.)
Jurisdictional Alternate 1 Alternate 2

Wetland 1 0.04 0.09 0.13 0.10
Wetland 2 <0.01 0.06 0.06 0.03
Total 0.04 0.15 0.19 0.13
The existing bridge is to be removed without dropping components into Abbott's Creek.
Therefore, no fill is to be deposited into waters of the United States.
2. Permit
Impacts to jurisdictional areas are anticipated from the proposed project. As a result,
construction activities will require permits and certifications from regulatory agencies in charge
of protecting the water quality of public water resources.
This project may be processed as a Categorical Exclusion (CE) under Federal Highway
Administration (FHWA) guidelines. The USACE has made available Nationwide Permit (NWP)
23 (67 FR 2020, 2082; January 15, 2002) for CEs due to minimal impacts to waters of the U.S.
expected with bridge construction. DWQ has made available a General 401 Water Quality
Certification for NWP 23 (GC 3403). If temporary structures are necessary for construction
activities, access fills, or dewatering of the site, then a NWP 33 (67 FR 2020, 2087; January 15,
2002) permit and the associated General 401 Water Quality Certification (GC 3366) will be
required. Impacts to vegetated wetlands may be authorized under NWP 3 (67 FR 2020, 2078)
and the associated Genera1401 Water Quality Certification (GC 3376). In the event that NWPs
23, 33, and 3 will not suffice, impacts attributed to bridge replacement and associated approach
improvements may qualify under General Bridge Permit (GP) 031 issued by the Wilmington
USACE District. DWQ has made available a General 401 Water Quality Certification for GP
031 (GC 3404). Notification to the Wilmington USACE District office is required if this general
permit is utilized.
3. Mitigation
The USACE has adopted through the Council on Environmental Quality (CEQ) a wetland
mitigation policy which embraces the concept of "no net loss of wetlands" and sequencing. The
purpose of this policy is to restore and maintain the chemical, biological, and physical integrity
of waters of the United States, and specifically wetlands. Mitigation of wetland impacts has
been defined by the CEQ to include: avoiding impacts (to wetlands), minimizing impacts,
18

rectifying .impacts, reducing impacts over time and compensating for impacts (40 CFR 1508.20).
Each of these three aspects (avoidance, minimization, and compensatory mitigation} must be
considered sequentially.
Avoidance mitigation examines all appropriate and practicable possibilities of averting impacts
_ to waters of the United States. According to a 1990 Memorandum of Agreement (MOA)
between the Environmental Protection Agency (EPA) and the USACE, in determining
"appropriate and practicable"_measwes to offset unavoidable impacts, such measwes should be
appropriate to the scope and degree of those impacts and practicable in terms of cost, existing
technology and logistics in light of overall project purposes.
Minimization includes the examination of appropriate and practicable steps to reduce the adverse
impacts to waters of the United States. Implementation of these steps will be required through
project modifications and permit conditions. Minimization typically focuses on decreasing the
footprint of the proposed project through the reduction of median widths, right-of--way widths,
fill slopes, and/or road shoulder widths. All efforts will be made to decrease impacts to surface
waters.
Compensatory mitigation is not normally considered until anticipated impacts to waters of the
United States .have been avoided and minimized to the maximum extent possible. It is
recognized that "no net loss of wetlands" functions and values may not be achieved in each and
every permit action. In accordance with 15A NCAC 2H .0506(h), DWQ may require
compensatory mitigation for projects with greater than or equal #0 1.0 acre of impacts to
jurisdictional wetlands or greater than or equal to 150 lineaz feet of total perennial stream
impacts. Furthermore, in accordance with 67 FR 2020, 2092; January 15, 2002, the USACE
requires compensatory mitigation when necessary to enswe that adverse effects to the aquatic
environment aze minimal. The size and type of the proposed project impact and the function and
value of the impacted aquatic resowce are factors considered in determining acceptability of
appropriate and practicable compensatory mitigation. Appropriate and practicable compensatory
mitigation is required for unavoidable adverse impacts which remain after all appropriate and
_ practicable minimization has been required. Compensatory actions often include restoration,
preservation and enhancement, and creation of waters of the United States. Such actions should
be undertaken first in areas adjacent to or contiguous to the dischazge site.
Mitigation for Section 404 jurisdictional azeas may not need to be proposed for this project due
to the potentially limited nature of the project impacts. However, utilization of BMPs is
recommended in an effort to minimize impacts. Temporary impacts to floodplains associated
19

with construction activities could be mitigated by replanting disturbed areas with native riparian
species and removal of temporary fill material upon project completion. A final determination
regarding mitigation rests with the USACE and DWQ.
F. Rare and Protected Species
1. Federally Protected Species
Species with the .federal classification of Endangered (E), 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 term "Endangered Species" is defined as "any species which is in
danger of extinction throughout all or a significant portion of its range," and the term
"Threatened Species" is defined as "any species which is likely to become an Endangered
species within the foreseeable future throughout all or a significant portion of its range" (16
U.S.C. 1532).
Three federally protected species are listed for Davidson County (February 11, 2003 FWS list):
Bald eagle (Haliaeetus leucocephalus), bog turtle (Clemmys muhlenbergii), and Schweinitz's
sunflower (Helianthus schweinitzii) (FWS 2002a). The bald eagle is Threatened, the bog turtle is
Threatened due to similarity of appearance (T S/A), and Schweinitz's sunflower is Endangered.
Haliaeetus leucocephalus (Bald Eagle)
Threatened
Family: Accipitridae
Date Listed: March 11, 1967
The bald eagle is a large raptor with a wingspan greater than 6 feet. Adult bald eagles are dazk
brown with a white head and tail. Immature eagles are brown with whitish mottling on the tail,
belly, and wing linings. Bald eagles typically feed on fish but may also take birds and small
mammals. In the Cazolinas, nesting season extends from December~through May (Potter et al.
1980). Bald eagles typically nest in tall, living trees in a conspicuous location near open water.
Eagles forage over large bodies of water and utilize adjacent trees for perching (Hamel 1992).
Disturbance activities within a primary zone extending 750 to 1500 feet from a nest tree are
considered to result in unacceptable conditions for eagles (FWS 1987). The FWS recommends
avoiding disturbance activities, including construction and tree-cutting within this primary zone.
Within a secondary zone, extending from the primary zone. boundary out to a distance of 1.0 mile
from a nest tree, construction and land-clearing activities should be restricted to the non-nesting
period. The FWS also recommends avoiding alteration of natural shorelines where bald eagles
forage, and avoiding significant land-clearing activities within 1500 feet of known roosting sites.
20

BIOLOGICAL CONCLUSION: NO EFFECT
No suitable habitat or individuals were observed during field investigations, and NHP files list
no documentation of bald eagle within 2.0 miles of the project area.
Clemmys muhlenbergii (Bog turtle)
Threatened due to similarity of appearance
Family: Emydidae
Date Listed: May 1, 1997
The bog turtle is a small turtle reaching an adult size of approximately three to four inches. 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 has declined
drastically within the northern portion of its range due to over-collection and habitat alteration.
As a result, the FWS officially proposed in the January 29, 1997 Federal Register (62 FR 4229)
to list bog turtle as Threatened within the northern portion of its range, and within the southern
portion of its range, which includes North Carolina. The bog turtle was proposed for listing as
Threatened due to Similarity of Appearance. (T S/A) to the northern population. The listing
would allow incidental take of bog turtles in the southern population resulting from otherwise
lawful activity. 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.
Suitable habitat does exist for bog turtle within the project area. However, no individuals were
observed during field investigations and NHP files list no documentation of bog turtle within 2.0
miles of the project area. The bog turtle is listed as T(S/A) due to its similarity of appearance to
another raze species listed for protection. T(S/A) species are not subject to Section 7
consultation and a biological conclusion for this species is not required.
Helianthus schweinitzii (Schweinitz's sunflower)
Endangered
Family: Asteraceae
Date Listed: May 7, 1991
Schweinitz's sunflower is an erect, unbranched, rhizomatous, perennial herb that grows to
approximately 6 feet in height. The stem may be purple, usually pubescent, but sometimes
nearly smooth. Leaves are sessile, opposi#e on the lower stem but alternate above; in shape they
are lanceolate and average five to ten times as long as wide. The leaves are rather thick and stiff,
21

with a few small serrations. The upper leaf surface is rough and the lower surface is usually
pubescent with soft white hairs. Schweinitz's sunflower blooms from September to frost; the
yellow flower heads aze about 0.6 inch in diameter. The current range of this species is within
approximately 60 miles of Charlotte, North Carolina, occurring on upland interstream flats or
gentle slopes, in soils that aze thin or -clay in texture. The species needs open areas protected
from shade or excessive competition, reminiscent of Piedmont prairies. Disturbances such as
fire maintenance or regular mowing help sustain preferred habitat (FWS 1994).
BIOLOGICAL CONCLUSION: NO EFFECT
The project study azea does contain suitable habitat for Schweinitz's sunflower within
disturbed/maintained land, specifically roadside shoulders, utility line corridor, and forest edges.
However, NHP files reviewed on April 17, 20041ist no documentation of this species within 2.0
miles of the project study area. In addition, detailed surveys for Schweinitz's sunflower
conducted on August 19, 2004 revealed no individuals within the project study azea.
2. Federal Species of Concern
The February 11, 2003 FWS list includes a category of species designated as "Federal Species of
Concern" (FSC). A species with this designation is one 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). The FSC designation provides no federal protection
under the ESA for the species listed. NHP files list no documentation for FSC species within 2.0
miles of the project area.
Two FSC species are listed for Davidson County: the Carolina Darter (Etheostoma collis collis)
which has a state status of Special Concern, and Heller's trefoil (Lotus helleri~ which has a state
status of Significantly Rare throughout its range (FWS 2002x, Amoroso 2004, LeGrand and Hall
2001). Cazolina Darter habitat is sluggish to calm, clear to slightly turbid creeks and small rivers
over a bed of rnud, sand, and rock. The reach of Abbott's Creek within the project area does
provide suitable habitat for Cazolina darter. Heller's trefoil is typically found along roadsides
and other disturbed azeas such as fields and utility right-of--ways. Suitable habitat exists for this
species within the project azea. '
Candidate Species -The February 11, 2003 FWS list also includes a category of species
designated as "Candidate" (C1). A species with this designation is one that is a species under
consideration for official listing for which there is sufficient information to support listing. The
C1 designation provides no federal protection under the ESA for the species listed.
22

One Cl species is listed for Davidson County: Georgia aster (Aster georgianus) that has a state
status of Threatened (FWS 2002x, Amoroso 2004, LeGrand and Hall 2001). Georgia aster
populations typically prefer roadsides, woodland borders, dry rocky woods, and disturbed areas such
as fields and utility right-of--ways. Suitable habitat exists for this species within the project area.
However, NHP files list no documentation for C1 species within 2.0 miles of the project area.

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 36 CFR Part 800. Section 106
requires that for federally funded, licensed, or permitted projects having an effect on properties
listed in or eligible for the National Register of Historic Places, the Advisory Council on Historic
Preservation be given the opportunity to comment.
B. Historic Architecture
In a memorandum dated Mazch 10, 2004, the North Carolina State Historic Preservation Office
(HPO) determined the project would not affect any historic structures. Accordingly, NCDOT
architectural historians did not initiate a survey of the project azea. A copy of this memorandum
is included in the Appendix.
C. Archaeology
A memorandum from the HPO dated March 10, 2004 states that they aze awaze of no historic
resources that would be affected by the project. According, NCDOT did not initiate an
archaeological survey of the project area. A copy of the memorandum is included in the
Appendix.
VII. ENVIRONMENTAL EFFECTS
The project is expected to have an overall positive impact by replacing a potentially unsafe
bridge.
The project is considered a Federal "Categorical Exclusion" due to its limited scope and
environmental consequences.
23

The bridge replacement will not have an adverse effect on the quality of the human or natural
environment with the use of current NCDOT standards and specifications.
The project is not in conflict with any plan, existing land use, or zoning regulations. No
significant change in land use is expected to result from replacement of the bridge.
The studied route does not contain any bicycle accommodations, nor is it a designated bicycle
route; therefore, no bicycle accommodations have been included as part of this project.
No residential or business relocatees are anticipated as a result of the proposed project.
No adverse impacts on families or communities are anticipated.
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 area.
The proposed project is excluded from the Farmland Protection Policy Act (FPPA) since the
project is located within the urban area of High Point. (7 CFR Part 658)
There are no publicly owned parks, recreational facilities, or wildlife and waterfowl refuges of
national, state, or local significance in the vicinity of the project.
The project is an air quality "neutral" project, so it is not required to be included in the regional
emissions analysis and a project level CO analysis is not required. 40 CFR Part 51 is not
applicable because the proposed project is located in an attainment area. If vegetation or wood
debris is disposed of by burning, it shall be done in accordance with applicable local laws and
regulations of the North Carolina State Implementation Plan (SIP) for air quality in compliance
with 15 NCAC 2D.0520 and 1,990 Clean Air Act Amendments and the National Environmental
Policy Act. Traffic volumes will not increase or decrease because of the replacement of the
existing bridge. The noise levels will increase during the construction period, but will only be
temporary. This evaluation completes the assessment requirements for highway traffic noise of
Title 23, Code of Federal Regulations (CFR), Part 772 and for air quality (1990 Clean Air Act
Amendments and the National Environmental Policy Act) and no additional reports are required.
The results from apre-scoping geotechnical and geoenvironmental investigation performed by
the NCDOT Geotechnical Engineering Unit showed that no underground storage tank sites or
hazardous waste sites or apparent landfills were identified within the project limits. The
geotechnical pre-scoping report is included in the appendix.
24

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
A "start of study" letter was distributed to local officials and agencies requesting information and
concerns relative to the proposed study alternates. Their responses are included in the Appendix.
Due to the isolated nature of this bridge replacement project, no formal public involvement
- program was initiated.
IX. AGENCY COORDINATION
Letters requesting comments and environmental input were sent to the following agencies:
US Army Corps of Engineers -Wilmington District
*US Fish and Wildlife Service
US Department of Agriculture, Natural Resources Conservation Service
State Clearinghouse
*NC Department of Cultural Resources
*NC Wildlife Resources Commission, NC Division of Water Quality
Planning Director, Davidson County Planning & Zoning Department
Chairman, Davidson County Commissioners
*Superintendent, Davidson County Public Schools
Davidson County Emergency Management Services
Sheriff, Davidson County
Asterisks (*) indicate agencies from which written/oral comments were received. Scoping
comments and corresponding responses are given below. Copies of the comments received are
in the Appendix.
1. United States Department of Interior -Fish and Wildlife Service
Comment: "...we recommend conducting habitat assessments and surveying any
suitable habitat in the project areas for these species [listed on the Federal List of
Endangered and Threatened A'ildlife and Plants or Federal Species of Concern] prior to
any further planning or on-the-ground activities to ensure that no adverse impacts occur".
Response: A survey of the project area concluded this project will not affect any
threatened or endangered species.
25

Comment: "[Fish and Wildlife Service -Asheville Field Office officials] recommend
spanning structures, preferably bridges, in all cases".
Response: Bridge No. 142 will be replaced with a new bridge approximately 130 feet
long with a maximum clear roadway width of 40 feet.
Comment: "...off-site detours, which would reduce stream-bank disturbance, are
preferable to temporary on-site crossings".
Response: Alternate 2, replacing Bridge No. 142 on the north side while maintaining
traffic on the existing structure as an on-site detour, is the preferred alternative. An off-
site detour was investigated but was not considered appropriate because of the relatively
high traffic volumes (4200 vpd) and the lack of a suitable detour for local fire protection
vehicles.
2. North Carolina Division of Water Quality
Comment: "There aze 30-foot vegetated buffer requirements in WS waters in addition to
the requirements to minimize storm water runoff and maximize use of BMPs".
Response: Public road projects may be allowed within the buffer where no practicable
alternative exists, as long as built-upon area is mi~mi~ed, runoff is directed away from
surface waters, and the use of Best Management Practices (BMPs) is maximized. In
order to minimize impacts to water resources, NCDOT BMP's for the Protection of
Surface Waters will be strictly enforced during the entire life of the project.
3. North Carolina Wildlife Resources Commission
Comment: "...Abbotts [Creek is] classified WS-III waters. Sediment and erosion
control measures should adhere to the design standards for sensitive watersheds to protect
the water supply".
Response: NCDOT BMP's for the Protection of Surface Waters will be strictly enforced
during the entire life of the project. The necessary sedimentation and erosion control
measures will be determined during the final design and permitting process.
Comment: "Impacts to aquatic and terrestrial resources should be minimized. Standard
requirements and BMP's should apply".
26

Response: In order to minimize impacts to water resowces, NCDOT BMP's for the
Protection of Surface Waters will be strictly enforced during the entire life of the project.
4. Davidson County Schools -School Transportation Director
Comment: There are 14 school bus crossings on Bridge No. 142 per day. Re-routing bus
traffic would be difficult. Acceptable turn around areas would be preferred.
Response: The preferred alternate will maintain traffic with an on-site temporary detow.
School buses will not need to be re-routed, and turn around areas will not be necessary.

In reply to your correspondence dated February 10, 2004 (received February 18, 2004) to Cynthia Van der Wiele,
in which you requested comments for the referenced projects, the NC Division of Water Quality has the following
comments:
I_. General Comments Rel~ardiinlE* Bridge Replacement Proiects
1: If corrugated metal pipe arches, reinforced concrete pipes, or concrete box culverts are used to replace the
bridge, then DWQ recommends the use of Nationwide Permit No. 14 rather than Nationwide Permit 23.
2. Bridge demolition should be performed using Best Management Practices developed by NCDOT.
3. DWQ prefers spanning structures. Spanning structures usually do not require work within the stream and do .
not require stream channel realignment. The horizontal and vertical clearances provided by bridges allows for
human and wildlife passage beneath the structure, does not block fish passage, and does not block navigation by
canoeists and boaters.
4, .Bridge deck drains should not discharge directly into the stream; stormwater should be directed across the
bridge and pre-treated through site-appropriate means (grassed swales, pre-formed scour holes, vegetated
buffers, etc.) before entering the stream. Please refer to NCDOT Best Management Practices for the
Protection of Surface Waters
5. Live concrete should not be allowed to contact the water in or entering into the stream. Concrete is mostly
made up of lime (calcium carbonate) and when in a dry or wet state (not hardened) calcium carbonate is very _ _
soluble in water and has a pH of approximately 12. In an unhardened state concrete or cement will change the
pH of fresh water to very basic and will cause fish and other macroinvertebrate kills.
6. If possible, bridge supports (bents) should not be placed in the stream.
7. If temporary access roads or detours are conswcted, they should be removed back to original ground
elevations immediately upon the completion of the project. Disturbed areas should be seeded or mulched to
stabilize the soil and native tree species should be planted with a spacing of not more than 10'x10'. 1f
possible, when using temporary structures the area should be cleared but not grubbed. Clearing the area with
chain saws, mowers, bush-hogs, or other mechanized equipment and leaving the stumps and root mat intact,
allows the area to re-vegetate naturally and minimizes disturbed soil.

~El~

8. A clear bank (rip rap-free) area of at least 10 feet should remain on each side of the steam underneath the
bridge.
9. Sedimentation and erosion control measures sufficient to protect water resources must be implemented prior
to any ground disturbing activities. Structures should be maintained regularly, especially following rainfall '
events.
10. Bare soil should be stabilized through vegetation or other means as quickly as feasible to prevent sedimentation '
of water resources.
11. All work in or adjacent to stream waters should be conducted in a dry work area. Sandbags, rock berms,
cofferdams, or other diversion structures should be used where possible to prevent excavation in flowing
water.
12. Heavy equipment should be operated from the bank rather than iri stream channels in order to minimize
sedimentation and reduce the likelihood of introducing other pollutants into streams. This equipment should
be inspected daily and maintained to prevent contamination of surface waters from leaking fuels, lubricants,
hydraulic fluids, or other toxic materials.
IL General Comments if Renlacin~ the Bride with a Culvert
1. The culvert must be designed to allow for. aquatic life and fish passage. Generally, the culvert or pipe invert
should be buried:at least 1 foot below the natural streambed (measured from the natural thalweg depth). If
multiple barrels ataze required, barrels other than the base flow barrel(s) should be placed on or neaz stream
bankfull or floodplain bench elevation. (similar to Lyonsfield design). These should be reconnected to
floodplain benches as appropriate. This may be accomplished by utilizing sills on the upstream end to restrict
or divert flow to the base flow barrel(s). Silled banels should be filled with sediment so as not to cause noxious
-- or mosquito breeding conditions. Sufficient water depth should be provided in the base flow barrel during low
flows to accommodate fish movement. If culverts are longer than 40-50 linear feet, alternating or notched
baffles should be installed in a manner that mimics existing stream pattern. This should enhance aquatic life
passage: 1) by depositing sediments in the barrel, 2) by maintaining channel depth and flow regimes, and 3) by
providing resting places for fish and other aquatic organisms. )n essence, the base flow barrel(s) should provide
a continuum of water depth and channel width without substantial modifications of velocity.
- ~2. If multiple pipes or cells aze used, at least one pipe or box should be designed to remain dry during normal
flows to allow for wildlife passage. ~ .
3, Culverts or pipes should be situated along the existing channel alignment whenever possible to avoid channel
realignment. Widening the stream channel must be avoided.. Stream channel widening at the inlet or outlet
end of structures typically decreases water velocity causing sediment deposition that requires increased.
maintenance and disrupts aquatic life passage.
4. Riprap should not be placed in the active. thalweg channel or placed in the streambed in a manner that
precludes aquatic life passage. Bioengineering boulders or structures should be professionally designed,
sized, and installed.
In most cases, we prefer the replacement of the existing structure at the same location with road closure. If road
closure is not feasible, a temporary detour should be designed and located to avoid wetland impacts, minimize the
need for clearing and to avoid destabilizing stream banks. If the structure will be on a new alignment, the old
structure should be removed and the approach fills removed from the 100-year floodplain. Approach fills should
be removed down to the natural ground elevation. The area should be stabilized with grass and planted with
native tree species. Tall fescue should not be used in riparian areas. If the area that is reclaimed was previously
wetlands, NCDOT should restore the area to wetlands. If successful, the site may be used as wetland mitigation
for the subject project or other projects in the watershed.

III. Proiect-Specific Comments

Habitat Conservation Program, NCWRC
DATE: August 12, 2004
SUBJECT: Scoping review of NCDOT's proposed replacement of Bridge No. 142 on SR
1741 over Abbotts Creek and Bridge No. 141 on SR 1741 over Sprugeon Creek,
Davidson County. TIP Nos. B-4100 and B-4101.
North Carolina Department of Transportation (NCDOT) is requesting comments from the
North Cazolina Wildlife Resources Commission (NCWRC) regarding impacts to fish and
wildlife resources resuhing from the subject project. Staff biologists have reviewed the
information provided and have the following preliminary comments. These comments aze
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). - -
Our standard recommendations for bridge replacement projects of this scope are as
follows:
1. We generally prefer spanning structures. Spanning structures usually do not require work
within the stream and do not require stream channel realignment. The horizontal and
.vertical clearances provided by bridges allows for human and wildlife passage beneath
the structure, does not block fish passage, and does not block navigation by canoeists and
boaters.
2. Bridge deck drains should not discharge duectly into the stream.
3. Live concrete should not be allowed to contact the water in or entering into the stream
4. If possible, bridge supports (bents) should not be placed in the stream

5. If temporary access roads or detows aze constructed, they should be removed back to
original ground elevations immediately upon the completion of the project. Disturbed
areas should be seeded'or mulched to stabilize the soil and native tree species should be
planted with a spacing of not more than l 0'x10'. If possible, when using temporary
structures the area should be cleared but not grubbed. Clearing the area with chain saws,
mowers, bush-hogs, or other mechanized equipment and leaving the stumps and root mat
intact, allows the area to revegetate naturally and minimizes disturbed soil.
6. A clear bank (riprap free) area of at least 10 feet should remain on each side of the stream
underneath the bridge.
7. In trout waters, the N.C. Wildlife Resowces Commission reviews all U.S. Army Corps of
Engineers nationwide and general `404' permits. We have the option of requesting
additional measures to protect trout and trout habitat and we can recommend that the
project require an individual `404' permit.
8. In streams that contain threatened or endangered species, Mr. Logan Williams with the
NCDOT -ONE should be notified. Special measwes to protect these sensitive species
may be required. NCDOT should also contact the U.S. Fish and Wildlife Service for
information on requirements of the Endangered Species Act as it relates to the project.
9. In streams that are used by anadromous fish, the NCDOT official policy entitled "Stream
Crossing Guidelines for Anadromous Fish Passage (May 12, 1997)" should be followed.
10. In areas with significant fisheries for sunfish, seasonal exclusions may also be
recommended.
11. Sedimentation and erosion control measures sufficient to protect aquatic resources must
be implemented prior to any ground disturbing activities. Structures should be
maintained regularly, especially following rainfall events.
12. 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
13. All work in or adjacent to stream waters should be conducted in a dry work azea.
Sandbags, rock berms, cofferdams, or other diversion structwes should be used where
possible to prevent excavation in flowing water.
14. Heavy equipment should be operated from the bank rather than in stream channels in
order to minimize sedunentation and reduce the likelihood of introducing other pollutants
into streams.
15. Only clean, sediment-free rock should be used as temporary fill (causeways), and should
be removed without excessive distwbance of the natural stream bottom when
construction is completed.

B-4100 & B-4101, SR 1741
Abbotts & Sprugeon Creeks, Davidson Co.
August 12, 2004
16. During subsurface investigations, equipment should be inspected daily and maintained to
prevent contamination of surface waters from leaking fuels, lubricants, hydraulic fluids,
or other toxic materials.
17. If culvert installation is being considered, conduct subsurface investigations prior to
structure design to determine design options and constraints and to ensure that wildlife
passage issues aze addressed.
If corrugated metal pipe arches; reinforced concrete pipes, or concrete box culverts are
used:
1. The culvert must be designed to allow for aquatic life and fish passage. Generally, the
culvert or pipe invert should be buried at least 1 foot below the natural streambed
(measured from the natural thalweg depth). If multiple barrels aze required, barrels other
than the base flow barrel(s) should be placed on or near stream bankfull or floodplain
bench elevation (similar to Lyonsfield design). These should be reconnected to
floodplain benches as appropriate. This may be accomplished by utilizing sills on the
upstream end to restrict or divert flow to the base flow barrel(s). Silted barrels should be
filled with sediment so as not to cause noxious or mosquito breeding conditions.
Sufficient water depth should be provided in the base flow barrel during low flows to
accommodate fish movement. If culverts are longer than 40-50 linear feet, ahernating or
notched baffles should be installed in a manner that mimics existing stream pattern. This
should enhance aquatic life passage: 1) by depositing sediments in the barrel, 2) by
maurtaining channel depth and flow regimes, and 3) by providing resting places for fish
and other aquatic organisms. In essence, the base flow barrel(s) should provide a
continuum of water depth and channel width without substantial modifications of
velocity.
2. If multiple pipes or cells are used, at least one pipe or box should be designed to remain
dry during normal flows to allow for wildlife passage. -
3. Culverts or pipes should be situated along the existing channel alignment whenever
possible to avoid channel realignment. Widening the stream channel must be avoided.
Stream channel widening at the inlet or outlet end of structures typically decreases water
velocity causing sediment deposition that requires increased maintenance and disrupts
aquatic life passage.
4. Riprap should not be placed in the active thalweg channel or placed in the streambed in a
manner that precludes aquatic life passage. Bioengineering boulders or structures should
be professionally designed, sized, and installed.
In most cases, we prefer the replacement of the existing structure at the same location
with road closure. If road closure is not feasible, a temporary detour should be designed and
located to avoid wetland impacts, minimize the need for clearing and to avoid destabilizing

and the approach fills removed from the 100-year floodplain. Approach fills should be removed
down to the natural ground elevation. The area should be stabilized with grass and planted with
native tree species. Tall fescue should not be used in riparian areas. If the area that is reclaimed
was previously wetlands, NCDOT should restore the area to wetlands. If successful, the site may
be used as wetland mitigation for the subject project or other projects in the watershed.
Project specific comments:
1. B-4100 and B-4101, Davidson Co., Bridge No. 142 on SR 1741 over Abbotts Creek and
Bridge No. 141 on SR 1741 over Sprugeon Creek. Both Abbotts and Sprugeon Creeks are
classified WS-III waters. Sediment and erosion control measures should adhere to the design
standazds for sensitive watersheds to protect the water supply. No other special concerns are
indicated at this time. Impacts to aquatic and terrestrial resources should be minimized.
Standard requirements and BMP's should apply.
We request that NCDOT routinely minimize adverse impacts to fish and wildlife
resources in the vicinity of bridge replacements. The NCDOT should install and maintain
sedimentation control measwes throughout the life of the project and prevent wet concrete from
contacting water in or entering into these streams. Replacement of bridges with spanning
structures of some type, as opposed to pipe or box culverts, is recommended in most cases.
Spanning structures allow wildlife passage along streambanks, reducing habitat fragmentation
and vehicle related mortality at highway crossings.
If you need further assistance or information on NCWRC concerns regarding bridge
replacements, please contact me at [phone]. Thank you for the opportunity to review and
comment on this project.

B-4100, Bridge No. 142 on SR 1741 over Abbotts Creek
B-4101, Bridge No. 141 on SR 1741 over Abbotts Creek
The Project Development and Environmental Analysis Branch of the North
Carolina Department of Transportation (NCDOT) has begun studying proposed
improvements to the subject bridge replacement projects. The projects are included in the
NCDOT's 2004-2010 Transportation Improvement Program and are scheduled for right-
of-way in fiscal year 2005 and construction in fiscal year 2007.
B-4100, Bridge No. 142 on SR 1741 over Abbotts Creek
The existing two-lane structure, constructed in 1949, crosses over Abbotts Creek
and is 106 feet long and 24 feet wide.
The following alternatives will be studied for this bridge project:
- Do-Nothing
- Rehabilitate the Existing Structure
- Replace on the north side maintaining traffic on the existing structure as an

- Do-Nothing
- Rehabilitate the Existing Structure
- Replace at existing location by closing the existing roadway and
maintaining traffic with anoff-site detour.
- Replace at existing location maintaining traffic with a temporary structure
and detour on north side (note: this alternative will not be pursued if
preliminary investigation indicates that the temporary detour will require a
taking of the house adjacent to the roadway and creek in the northeast
quadrant).
- Replace at existing location maintaining traffic with a temporary structure
and detour on south side.
If the structure is replaced at its existing location utilizing anoff--site detour route,
SR 1741 will be closed to through traffic during the construction of the replacement
structure. If you feel this would create undue travel hardships to the community please
advise. Any comments regarding potential impacts to School Bus Routings and
Emergency Response Units (fire, rescue, police, etc.) would be especially helpful.
We would appreciate any information you have that would be helpful in
evaluating potential community and environmental impacts of the above projects. If
applicable, please identify any permits and/or approvals required by your agency.
Please note that there will be no formal interagency scoping meeting for these
projects. This letter constitutes solicitation for scoping comments related to the projects.
It is desirable that you respond by March 31, 2004, so that your comments can be used in
the preparation of a proposed Categorical Exclusion for the above projects. You may

The N. C. Department of Transportation has begun the planning process to replace the
above bridge, which is nearing the end of its useful life. Construction is planned for year 2006. '
Alternative methods of replacing the bridge will be studied. Some alternatives may rewire
road closure at the bridge site. In that case, all traffic would be detoured onto other local roads. '
The type of bridge or structure. that we select will de'tcrmine how long the road-would have
to remain closed. However, the time of closure would not be longer than 8-12 months:
V:'e wouldlike to )Grow the spevific number of bus.cros~iags p::~ day-and if road closure
could be handled by re-muting or other changes, or if-it would create an unworkable situation for

GEOTECHl~'ICAL ISSUES
Techniques and AZethodologies
The geotechnical investigation consisted of a reconnaissance conducted on May 26, 2004 and
one Standard Penetration Test conducted on May 27, 2004. The boring was conducted on the
shoulder of the existing roadway, in the southwest quadrant. It was collared about 15 feet above
the streambed elevation.
Findings
The project area is within a very large floodplain associated with Abbotts Creek. The test boring
found six feet of roadway fill over approximately twelve feet of very soft alluvial clay over
residual soil. Weathered rock was encountered at 30' depth. Split spoon samples of the
weathered rock are consistent with the mapped rock unit PPg, Granitic Rock of the Charlotte
Belt.
There appears to be good potential for lateral migration of the stream within the floodplain.
Streambank scour is occurring to the left (upstream) and to the right (under the existing bridge).
Anticipated Impacts
Consolidation of the alluvial clay is likely. This may require a waiting period between placement
of the new fill and pile driving. Stabilization of the stream banks will need to be addressed.
Based on limited preliminary data, a drilled shaft foundation seems likely.
If there are any questions regarding these Geotechnical comments, please contact Clinton B.

the project study area that are or may be contaminated and therefore result in increased project
costs and future liability if acquired by the Department. GeoEnvironmental impacts may include,
but are not limited to, active and abandoned underground storage tank (UST) sites, hazardous
waste sites, regulated landfills and unregulated dumpsites.
Technigues/Methodologies Used
The Geographical Information System (GIS) was consulted to identify known environmentally
impacting sites in relation to the project corridor. GeoEnvironmental Section personnel
conducted a field reconnaissance survey along the project comdor on April 26, 2004.
Findings
Underground Storage Tank (UST) Facilities
Based on our study, there are no UST sites identified within the project limits.
Hazardous Waste Sites
No Hazardous Waste Sites were identified within the project limits.
Land Fills
No apparent landfills were identified within the project limits.
Other GeoEnvironmental Concerns
No additional sites were encountered within the project limits.
Anticipated Impacts
We anticipate no monetary or scheduling impacts resulting from contaminated properties within
the project limits.
The GeoEnvironmental Section observed no additional contaminated properties during the field
reconnaissance and regulatory agencies' records search. Please note that discovery of additional
sites not recorded by regulatory agencies and not reasonably discernable during the project
reconnaissance may occur. The GeoEnvironmental Section should be notified immediately after
discovery of such sites so their potential impact(s) maybe assessed.

***Incidental/migrant 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.

ENDANGERED, THREATENED, AND CANDIDATE SPECIES AND FEDERAL
SPECIES OF CONCERN, DAVIDSON, DAME,
FORSYTH, AND STOKES COUNTIES, NORTH CAROLINA
This list was adapted from the North Carolina Natural Heritage Program's County Species List. It is a
listing, for Davidson, Davie, Forsyth, and Stokes Counties, of North Cazolina's federally listed and
proposed~endangered, threatened, and candidate species and Federal species of concern (for a complete
list of rare species in the state, please contact the I~iorth Carolina Natural Heritage Program). The
information in this list is compiled from a variety of sources, including field surveys, museums and
herbaria, literature, and personal communications. The North Carolina Natural Heritage Program's
database is dynamic, with new records being added and old records being revised as new information is
received. Please note that this list cannot be considered a definitive record of listed species and Federal
species of concern, and it should not be considered a substitute for field surveys.
Critical habitat: Critical habitat is noted, with a description, for the counties where it is designated or
proposed.
Aquatic species: Fishes and aquatic invertebrates are noted for counties where they are known to occur.
However, projects may have effects on downstream aquatic systems in adjacent
counties.

Our records for these counties and project areas indicate no known locations of listed species in
the project areas. However, we recommend conducting habitat assessments and surveying any
suitable habitat in the project azeas for these species prior to any further planning or
on-the-ground activities to ensure that no adverse impacts occur.
We aze interested in the types of structures that will replace the existing bridges and would
recommend spanning structures, preferably bridges,in all cases. In addition, off-site detours,
which would reduce stream-bank disturbance, aze preferable to temporary on-site crossings. We
look forward to reviewing the completed categorical exclusion documents.

Subject: Scoping Comments for Five Bridge Replacement Proposals, Stokes, Davidson, Forsyth, I
and Davie Counties, North Cazolina
We have reviewed the subject bridge replacement proposals and providethe following comments
in accordance with the Fish and Wildlife Coordination Act; as amended (16 U.S.C. 661-667e),
and section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act).
Given the eazly stages of development for these projects, our comments aze limited primarily to
the laiown locations of listed species and federal species of concern. When the categorical
exclusions are prepared and more information is available regazding environmental effects, we
can offer more substantive comments.
Enclosed is a species list for the four counties included in this package. This list provides the
names of species on the Federal List of Endangered and Threatened Wildlife and Plants as well
as federal species of concern. Federal species of concern are not legally protected under the Act
and are not subject to any of its provisions, including section 7, unless they aze 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 aze
found in the vicinity of your projects. Our records indicate the following:
Stokes County - B-4281. Bridge No. 60 on NC 8 and 89 over the Dan River (our
Log No. 4-2-04-122) -Our records for Stokes County indicate known locations of
the federally endangered James spinymussel (Pleurobema collina) in the project
area. It is likely that James spinymussel individuals would be affected by this
project; if that is the case, formal consultation will be required. In addition, there
are occurrences of the federally endangered small-anthered bittercress
(Cardamine micrantherea) near the project area.
