Subject: Modification to the Nationwide 23 and 33 permit, issued on December 5,
2003 (Action ID 200321265 and 200321266), for the replacement of Bridge
No. 404 over South Potts Creek on SR 1147, Davidson County. Federal Aid
Project No. BRSTP-1147(3), State Project No. 8.260440 1, TIP Project No. B-
4334.
Please find enclosed a revised permit drawing plan view and summary sheet for the
above-mentioned project. On December 5, 2003 the USACE issued Nationwide 23 and
33 Permits for the above-mentioned project that included a relocation of 56 feet of an
Unnamed Tributary to South Potts Creek using natural channel design. Officials from
NCDOT and NCWRC reviewed the proposed channel work in the field and a new
alignment for the stream relocation has been proposed. The new alignment eliminates the
sharp bends in the channel and follows a more natural pattern. Impacts from the original
alternative totaled 56 feet, and the new alignment will result in 120 feet of fill in the
stream and will result in 115 feet of natural channel design, no additional mitigation is
proposed. NCDOT and NCWRC officials concluded that this alignment would result in a
more stable stream and prevent future washouts. No changes are proposed to the cross-
sectional area, width, depth, or channel slope approved in the current permit.
Regulatory Approvals
The NCDOT requests that the USACE modify the Nationwide 23 and 33 Permit, issued
on December 5, 2003. We have also forwarded two copies to the NCDWQ for their
records. All general conditions of the Water Quality Certifications will be met therefore
no written concurrence is required.

Subject: Supplement to the Nationwide 23 and 33 applications, submitted on
August 15, 2003, for the replacement of Bridge No. 404 over South Potts
Creek on SR 1147, Davidson County. Federal Aid Project No. BRSTP-
1147(3), State Project No. 8.260440 1, TIP Project No. B-4334.
On August 15, 2003, the NCDOT submitted a Nationwide 23 and 33 application for the
replacement of Bridge No. 404 over South Potts Creek on SR 1147. On September 22,
2003 through email communication the USACE requested that the NCDOT provide more
information regarding the stream relocation.
The USACE requested that the NCDOT provide more information on the length of
proposed relocation, how the relocation of the unnamed tributary was designed, if the
relocation is within the Right-of-way, how the NCDOT plans on stabilizing the stream,
and a planting plan. A revised permit sheet 3 has been included showing a cross section
of the relocation, sheet 3B showing the stream relocation at a larger scale, sheet 3C
showing how the channel block will be constructed and a revised summary sheet. The
above mentioned questions are answered below.
Currently, the unnamed tributary meanders around the existing interior bents of the
existing bridge. The interior bents of the new bridge would impact the existing stream.
There is no other practical place to put the bents due to underground structures.
Therefore, the stream will be relocated to avoid the interior bent from the new bridge.

The stream relocation for the 56-foot portion of the unnamed tributary to South Potts
Creek was designed to match the existing stream cross sectional area of 35 square feet.
The entire portion of the stream relocation is located within the proposed right-of-way.
The proposed stream has a cross sectional area of 42 square feet. The area is slightly
larger because 3:1 side slopes were used to decrease erosion. Coir fiber matting will be
used to stabilize the side slopes of the stream relocation. The five-foot base width and
three-foot depth of the proposed stream is the same as the existing stream. The drainage
area for the stream is 3.63 square miles. Using the Manning equation for the open
channel hydraulips for a, stream section with a five-foot base, 3:1 side slopes, three-foot
depth and a slope of 1.09 percent, yields a discharge of 210 cubic feet per second with a
velocity of 5.0 feet per second. The 2 year discharge calculated using the USGS Report
01-4207 for the Rural Blue Ridge-Piedmont region yields a discharge of 330 feet per
second. The area surrounding the stream relocation will be seeded with grasses to
minimize erosion.

Dear Mr. Alsmeyer:
LYNDo TIPPETT
SECRETARY
Subject: Nationwide 23 and 33 applications, for the replacement of Bridge No. 404
over South Potts Creek on SR 1147, Davidson County. Federal Aid Project
No. BRSTP-1147(3), State Project No. 8.2604401, TIP Project No. B-4334.
Please find enclosed three copies of the project planning report for the above referenced
project. The document states that Bridge No. 201 will be replaced with a new 210-foot
[64 meter (m)] long 30 foot [9 m] wide bridge on the existing alignment. Traffic will use
an offsite detour during construction. There are no permanent impacts to Waters of the
U.S. associated with this project. The only surface water impacted by this project is
South Potts Creek and Unnamed Tributary to South Potts Creek. All impacts will be
temporary consisting of 0.012 ac of temporary fill in surface waters. South Potts Creek is
located in the Yadkin River Basin and is classified by the Division of Water Quality as
Class C.
Demolition: The existing bridge has an asphalt wearing surface, and the remainder of the
bridge, both superstructure and substructure, is composed of reinforced concrete. Thus,
there is a potential for components of the bridge to be dropped into Waters of the United
States during construction. The asphalt wearing surface will be removed prior to
demolition without dropping any into the water.
The resulting temporary fill associated with the reinforced concrete components of the
bridge will be as much as approximately 197 cubic yards. During construction, Best
Management Practices for Bridge Demolition and removal will be followed.

Temporary Causeways
There will be 0.012 acres temporary impacts from the construction a rock causeway in
South Potts Creek and the UT for the construction of bridge 404 (see permit drawing
Sheets 3 and 6 of 6). Temporary rock causeway will be required to remove the interior
bent from the existing bridge. The causeways will consist of Class II riprap topped with a
layer of Class "A" riprap.
Restoration Plan: No permanent fill will result from the subject activity. The materials
used as temporary fill in the construction of the causeways will be removed. The
temporary fill areas will be graded back to the original contours. Elevations and contours
in the vicinity of the proposed causeways are available from the field survey notes.
Schedule for Restoration of Temporary Fill Area: It is assumed that the Contractor will
begin construction of the proposed causeways shortly after the date of availability for the
project. The Let date is December 2, 2003 with a date of availability of January 12, 2003.
Removal and Disposal: The causeways will be removed within 90 days of the removal of
the interior bent. The temporary rock causeways will be removed by the Contractor using
excavating equipment. All materials placed in the stream by the Contractor will be
removed. The Class II riprap that is removed may be used on end slopes where Class II
riprap is required at the discretion of the Engineer. All other materials removed by the
Contractor will be disposed of at an off site upland location.
FEDERALLY-PROTECTED SPECIES
Plants and animals with federal classifications of Endangered, Threatened, Proposed
Endangered, and Proposed Threatened are protected under provisions of Section 7 and
Section 9 of the Endangered Species Act of 1973, as amended. As of January 29, 2003,
the Fish and Wildlife Service (FWS) lists three federally protected species for Davidson
County (Table 1).

"E" - denotes Endangered (a species that is in danger of extinction throughout all or a signitcant portion of
its range).
"T"- denotes Threatened a species which is likely to become endangered species within the foreseeable
future throughout all or a significant portion of its range.
"T (S/A)- Threatened due to similarity of appearance, a species that is threatened due to similarity of
appearance with other rare species and is listed for its protection. These species are not biologically
threatened and are not subject to Section 7 consultation.
"*"-Proposed for delisting
A survey for bald eagle, and Schweinitz's sunflower was originally conducted by
NCDOT biologist on September 26, 2001 and a biological conclusion of "No Effect" was
issued. A re-survey for the Schweinitz's sunflower was conducted on August 14, 2003
and no individuals were found.
Regulatory Approvals
Section 404 Permit: It is anticipated that the construction of the causeways will be
authorized under Section 404 Nationwide Permit 33 (Temporary Construction Access and
Dewatering). We are, therefore, requesting the issuance of a Nationwide Permit 33
authorizing construction of the causeway. All other aspects of this project are being
processed by the Federal Highway Administration as a "Categorical Exclusion" in
accordance with 23 CFR 771.115(b). Therefore, we do not anticipate requesting an
individual permit, but propose to proceed under a Nationwide 23 as authorized by a
Nationwide Permit 23 (FR number 10, pages 2020-2095; January 15, 2002).
Section 401 Permit: We anticipate 401 General Certifications numbers 3361 and 3366
will apply to this project. In accordance with 15A NCAC 2H .0501(a) we are providing
two copies of this application to the North Carolina Department of Environment and
Natural Resources, Division of Water Quality, for their records.

Note that the attached SHPO letter dated March 30, 2001, states that a
"high potential for archeological sites exists ...when (new) alignment is selected,
submit drawings so that we can determine (if) an archeological survey is needed."
This request refers to the initially favored alternate at the scoping meeting. This
alternate would have been on new alignment, causing new disturbance in the area,
thus possibly requiring an archeological survey. When the "replace at same
location alternate was instead agreed upon, the SHPO verbally agreed that there
was no need for a survey. (reference personal communication Dennis Pipkin with
Tom Padgett, NCDOT Archeology supervisor.)

From: David Brook "V?z k?,?
Deputy State Historic Preservation Officer
Re: Replacement of Bridge No. 404 on SR 1147 over South Potts Creek,
TIP No. B-4334, Davidson County, ER 00-7546
On October 12, 1999, April Montgomery of our staff met with North Carolina
Department of Transportation (NCDOT) staff for a meeting of the minds concerning the
above project. We reported our available information on historic architectural and
archaeological surveys and resources along with our recommendations. NCDOT
provided project area photographs and aerial photographs at the meeting.
Based upon our review of the photographs and the information discussed at the meeting,
we offer our preliminary comments regarding this project.
In terms of historic architectural resources we are aware of no historic structures located
within the area of potential effect. We recommend that no historic architectural survey
be conducted for this project.
In terms of archaeological resources there is a high potential for sites within the proposed
project area. When an alignment is selected please submit detailed drawings of that
alignment so that we can determine whether or not an archaeological survey is needed.
The above comments are made pursuant to Section 106 of the National Historic
Preservation Act and the Advisor), Council on Historic Preservation's Regulations for
Compliance with Section 106 codified at 36 CFR Part 800.
Thank you for your cooperation and consideration. If you have any questions concerning
the above comment, contact Renee Gledhill-Earley, Environmental Review Coordinator,
at 919 733-4763.

Eric,
We've got it. DWQ's main concern is that the relocation won't create stream instability. One
question I have is why they are using grasses rather than replanting with woody vegetation in
the area surrounding the stream relocation. I know it's only 56 feet ...but we do have a
standard condition in NW's about replanting the riparian corridor along the construction zone
once the construction has been completed:
1. Riparian vegetation must be reestablished within the construction limits of the project
by the end of the growing season following completion of construction.

NCDOT (Brett Feulner) sent a supplement to the application dated 10/31/03. We received it on
11 /7/03. It provides some additional information about the relocation. You and the other agencies (with
the exception of USEPA) were on the copies furnished list.
My plan is to forward a copy of the supplement to Becky Fox of USEPA, then give the agencies at least
a couple of weeks to review the additional info and provide comments. I will coordinate with you before
I make any decisions on this.

Hi Eric,
I put this bridge project on hold because I had heard thru you that DOT
was planning on-site stream relocation (they hadn't included that detail
or the plans with their application). Just want to follow up on that;
where are we with it? I haven't gotten anything from DOT. I think it
was a NW 23, but can't remember.
Thanks. Cynthia

1.0 INTRODUCTION
The following Natural Resources Technical Report is submitted to assist in the
preparation of a Categorical Exclusion (CE) for the proposed project. The purpose of
this report is to inventory and describe the natural resources which occur within the
proposed right-of-way boundaries and which are likely to be impacted by the proposed
action. Assessments of the nature and severity of probable impacts to these natural
resources are provided, along with recommendations for measures that will minimize
resource impacts.
This report identifies areas of particular environmental concern that may affect
the selection of a preferred alignment or may necessitate changes in design criteria.
Such environmental concerns should be addressed during the preliminary planning
stages of the proposed project in order to maintain environmental quality in the most
efficient and effective manner. The analyses contained in this document are relevant
only in the context of the existing preliminary project boundaries and design. If design
parameters and criteria change, additional field investigations may be necessary.
1.1 PROJECT DESCRIPTION
The proposed bridge project on SR 1147 crosses South Potts Creek in Davidson
County located approximately 2 miles southwest of Davidson (Figure 1). The project
calls for the replacement of Bridge No. 404 with a bridge. The project length totals
approximately 500 feet. The existing right-of-way is 60 feet with a proposed right-of-way
of 60 feet. The existing cross section is a two-lane shoulder section bridge. The
proposed cross section is a two-lane shoulder section bridge.
There are two alternates being considered for this project:
Alternate 1: Replace the bridge on existing alignment, and detour traffic over existing
local roads.
Alternate 2: Replace the bridge on existing alignment, and maintain traffic on-site with a
temporary detour structure (to the east of existing).
1.1.1 Bridge Demolition and Removal
Bridge No. 404 is located on SR 1147 over South Potts Creek in Davidson
County. The existing bridge has an asphalt wearing surface; and the remainder of the
bridge, both superstructure and substructure, is composed of reinforced concrete.
Thus, there is potential for components of the bridge to be dropped into Waters of the
2
United States during construction. The asphalt wearing surface will be removed prior to
demolition without dropping components into the water. The resulting temporary fill
associated with the reinforced concrete components of the bridge will be as much as
197 cubic yards. Bridge demolition is classified as a Case 3 ( there are no special
restrictions other than those outlined in Best Management Practices for Protection of
Surface Waters ).
Due to the potential sedimentation concerns resulting from demolition of
the bridge, where it is possible to do so, a turbidity curtain shall be included to
contain and minimize sedimentation in the stream.
For the protection of Surface Waters, Best Management Practices for
Bridge Demolition and Removal will be adhered to.
1.2 METHODOLOGY
Research was conducted prior to field investigations. Published resource
information pertaining to the project area was gathered and reviewed. Resources
utilized in this preliminary investigation of the project area include:
• Geological Survey (USGS) quadrangle maps (Lexington West, 1970).
• NCDOT aerial photographs of the project area (1:1200).
• NC Center for Geographic Information and Analysis Environmental Sensitivity,Base
Maps of Davidson County (1995).
• USDA Soil Conservation Service, currently known as Natural Resource
Conservation Service, Soil Survey of Davidson County, North Carolina (1994).
Water resource information was obtained from publications of the Department of the
Environment and Natural Resources (DENR, 1993). Information concerning the
occurrence of federal and state protected species in the study area was obtained from
the US Fish and Wildlife Service (FWS) list of protected and candidate species (June
16, 2000) and from the N.C. Natural Heritage Program (NCNHP) database of rare
species and unique habitats. NCNHP files were reviewed for documented occurrences
of state or federally listed species and locations of significant natural areas.
General field surveys were conducted along the proposed alignment by NCDOT
Natural Resources Specialists, Clay Willis and Jeff Burleson, on October 11, 2000.
Water resources were identified and their physical characteristics were recorded. Plant
communities and their associated wildlife were also identified and described. Terrestrial
community classifications generally follow Schafale and Weakley (1990) where
possible, and plant taxonomy follows Radford, et al. (1968). Animal taxonomy follows
Martof, et al. (1980), Menhenick (1991), Potter, et al. (1980), and Webster, et al. (1985).
Vegetative communities were mapped utilizing aerial photography of the project
site. Predictions regarding wildlife community composition involved general qualitative
3
habitat assessment based on existing vegetative communities. Wildlife identification
involved using a variety of observation techniques: qualitative habitat assessment
based on vegetative communities, active searching, identifying characteristic signs of
wildlife (sounds, scat, tracks and burrows).
Jurisdictional wetlands, if present, were identified and evaluated based on
criteria, established in the "Corps of Engineers Wetland Delineation Mahual"
(Environment Laboratory, 1987) and "Guidance for Rating the Values of Wetlands in
North Carolina" (Division of Environmental Management, 1995). Wetlands were
classified based on the classification scheme of Cowardin, et al. (1979).
1.3 TERMINOLOGY AND DEFINITIONS
For the purposes of this document, the following terms are used concerning the
limits of natural resources investigations. "Project area" denotes the area bounded by
the proposed right-of-way limits along the full length of the project alignment. "Project
vicinity" is defined as an area extending 1.0 km (0.6 mi) on all sides of the project
area, and "Project region" denotes an area equivalent in size to the area represented
by a 7.5 minute USGS quadrangle map, i.e. [163.3 sq. km (61.8 sq. mi)].
2.0 PHYSICAL RESOURCES
Soil and water resources that occur in the project area are discussed below with
respect to possible environmental concerns. Soil properties and site topography
significantly influence the potential for soil erosion and compaction, along with other
possible construction limitations or management concerns. Water resources within the
project area present important management limitations due to the need to regulate
water movement and the increased potential for water quality degradation. Excessive
soil disturbance resulting from construction activities can potentially alter both the flow
and quality of water resources, limiting downstream uses. In addition, soil
characteristics and the availability of water directly influence the composition and
distribution of flora and fauna in biotic communities, thus affecting the characteristics of
these resources.
2.1 REGIONAL CHARACTERISTICS
Davidson County is located in the center of the Piedmont physiographic region of
North Carolina. Most of the county is characterized. by gently rolling to hilly landscapes.
In the southern part of the county, a number of prominent peaks in the Uwharrie
mountain chain rise above the general landscapes. Eight or more of these peaks are at
an elevation of more than 1,000 feet. Flat Swamp Mountain, the highest, is at an
4
elevation of 1,180 feet. The lowest elevation in the count is about 510 feet at Badin
Lake on the southern boundary of the county. The county is drained by the Yadkin
River and its tributaries, which flow south or southwestward. Major watersheds are
Muddy Creek, Reedy Creek, Swearing Creek, Abbots Creek, Bushy Fork, Rich Fork,
Hamby's Creek, Flat Swamp Creek, and Lick Creek. The Yadkin Pee-Dee drainage
basin is the second largest basin in North Carolina. The drainage basin extends from
the eastern slopes of the Blue Ridge Mountains in Caldwell and Wilkes counties,
flowing southeasterly through North Carolina until it reaches Winyah Bay in South
Carolina. Many of the tributaries located in this basin have been classified as
outstanding resource waters. Land cover in the county is predominately in agriculture
fields and forest.
The project area topography along South Potts Creek is moderately sloping. The
banks of the floodplain of South Potts Creek have moderate to steep slopes. They are
well vegetated and appear to be stable. The floodplain of the creek is relatively small
and extends further to the west bank than to the east. A portion of the landscape to the
west of the creek has been altered for agricultural purposes and is now used as pasture
area. The bridge is located within a bend of the creek. Approximately 300 hundred feet
upstream an unnamed tributary runs into South Potts Creek.
2.2 SOILS
Generally, soils are characterized into Soil Associations or "General Soil
Mapping Units" with consistent patterns of soil, relief, and drainage. The project study
area in Davidson County lies in the Cecil-Pacolet "General Soil Mapping Unit". The
Cecil-Pacolet grouping is gently sloping to moderately steep, very deep, well drained
soils that have a loamy surface layer and a clayey subsoil; formed in material
weathered from felsic crystalline rocks on uplands. There are three soil types within the
Cecil-Pacolet mapping unit, located in the project area. A brief description of these soil
types is provided following Table 1.
Table 1. Soils occuring in the project area, Davidson County
Map Specific Mapping Unit % Slope Hydric Capability
Symbol Classification Unit
Ch Chewacla loam none Hydric-inclusions Ivw
EnD Enon fine sandy loam 8-15 Non-hydric Ive
CcB Cecil sandy loam 2-8 Non-hydric Ile
• Chewacla loam,(CW this nearly level, somewhat poorly drained soil is on first
bottoms along creeks and rivers throughout the northern, central, and western parts
of the county. Typically, the surface layer is brown loam about 9 inches thick. The
subsoil is about 43 inches thick. It is dark yellowish brown fine sandy loam in the
5
upper part; brown, yellowish brown, and light brownish gray sandy clay loam in the
next part. The soil generally is unsuited to building site development and
recreational uses because of the wetness and the flooding.
• Enon fine sandy loam,(EnD) this soil type is well drained soil located on narrow
ridges and on side slopes on uplands. Typically, the surface layer is yellowish brown
fine sandy loam about 8 inches thick. The subsoil is about 26 inches thick. The
upper part is strong brown clay, the next part is yellowish brown clay, and the lower
part is yellowish brown clay loam. The clayey subsoil, the slow permeability, the high
shrink-swell potential, and the slope are the main limitations affecting building site
development.
• Cecil sandy loam, (CcB) this well drained soil is on smooth ridges. It is on uplands in
the northern and western parts of the county. Typically, the surface layer is brown
sandy loam about 6 inches thick. The subsoil is about 52 inches thick. Permeability
is moderate. The shrink-swell potential is low. The depth to bedrock is more than 5
feet. The map unit has no major limitations affecting building site development or
recreational uses.
2.3 WATER RESOURCES
This section contains information concerning surface water resources likely to be
impacted by the proposed project. Water resource assessments include the physical
characteristics, best usage standards, and water quality aspects of the water resources,
along with their relationship to major regional drainage systems. Probable impacts to
surface water resources are also discussed, as are means to minimize impacts.
2.3.1 Best Usage Classification
Water resources within the study area are located in the Yadkin-Pee Dee
Drainage Basin; Division of Water Quality sub-basin number 03-07-04; United States
Department of Interior Hydrologic Unit is 03040103. There is one water resource, South
Potts Creek, in the project study area crossed by SR 1147. (Figurel)
Streams have been assigned a best usage classification by the Division of Water
Quality (DWQ), formerly Division of Environmental Management (DEM), which reflects
water quality conditions and potential resource usage. Unnamed tributaries receive the
same classification as the streams to which they flow. The classification for South Potts
Creek [ DEM Index No. 12-111, 9/01/74 ] is class C. Class C waters are protected for
secondary recreation, fishing, aquatic life including propagation and survival, and
wildlife. All freshwaters shall be classified to protect these uses at a minimum.
6
No waters classified as High Quality Waters (HQW), Water Source (WS I or
WS II), or Outstanding Resource Waters (ORW) occur within 1.6 km (1.0 mi) of the
project study area. South Potts Creek is not designated as a North Carolina
Natural and Scenic River, nor is it designated as a National Wild and Scenic
River.
2.3.2 Physical Characteristics of Surface Waters
South Potts Creek at the study area is approximately 4.5-6.1m (15.0-20.0 ft)
wide at the top of the bank and ranges in depth at normal stage from 5.0-10cm (2.0-4.0
in.) with an easterly, moderate to swift flow. The substrate in the study area is
composed of a sandy loam with pebble and cobble present in the streambed. This
creek, with moderate flow has relatively steep banks [ 1.8m (6 ft) deep at bank full ].
The banks are well vegetated and provide shading that keeps water temperatures in
the creek at cool levels. The pebble and cobble in the streambed creates riffles and
small pools of water that are important habitat areas for invertebrates and fish
inhabiting the creek. The bridge is located on a straight run of riffle and pool sequences
between two bends. On the day of the site visit, turbidity in the water column appeared
to be low. There was no evidence of elevated levels of sedimentation occurring in
South Potts Creek.
2.3.3 Water Quality
This section describes the quality of the water resources within the project area.
Potential sediment loads and toxin concentrations of these waters from both point
sources and nonpoint sources are evaluated. Water quality assessments are made
based on published resource information and existing general watershed
characteristics. These data provide insight into the value of water resources within the
project area to meet human needs and to provide habitat for aquatic organisms.
2.3.3.1 BENTHIC MACROINVERTEBRATE AMBIENT NETWORK
The Benthic Macroi nverteb rate Ambient Network (BMAN), managed by the
DWQ, is part of an ongoing ambient water quality monitoring program which addresses
long term trends in water quality. The program monitors ambient water quality by
sampling at fixed sites for selected benthic macroi nve rteb rates organisms, which are
sensitive to water quality conditions. Samples are evaluated on the number of taxa
present of intolerant groups [Ephemeroptera, Plecoptera, Trichoptera (EPT)] and a taxa
richness value (EPT S) is calculated. A biotic index value is also calculated for the
sample that summarizes tolerance data for all species in each collection. The two
rankings are given equal weight in final site classification. The biotic index and taxa
richness values primarily reflect the effects of chemical pollution and are a poor
7
measure of the effects of such physical pollutants as sediment. There are no BMAN
monitoring station within the project vicinity.
2.3.3.2 POINT SOURCE AND NONPOINT SOURCE DISCHARGERS
Point source dischargers located throughout North Carolina are permitted
through the National Pollutant Discharge Elimination System (NPDES) Program. Any
discharger is required to register for a permit. There is one permitted discharger within
the project vicinity located approximately 1000 ft to the east of the bridge (Permit #
N00040045, 8/13/93).
Nonpoint source discharge refers to runoff that enters surface waters through
stormwater or snowmelt. Agricultural activities may serve as a source for various forms
of nonpoint source pollutants. Land clearing and plowing disturbs soils to a degree
where they are susceptible to erosion, which can lead to sedimentation in streams.
Sediment is the most widespread cause of nonpoint source pollution in North Carolina.
Pesticides, chemical fertilizers, and land application of animal wastes can be
transported via runoff to receiving streams and potentially elevate concentrations of
toxic compounds and nutrients. Animal wastes can also be a source of bacterial
contamination and elevate biochemical oxygen demand (BOD). Drainage ditches on
poorly drained soils enhances the transportation of stormwater into surface waters
(DEM, 1993). The primary nonpoint pollution source in the project area is runoff from
SR 1147, which could contain petroleum product residues deposited by automobiles
driving on the road.
2.4 SUMMARY OF ANTICIPATED IMPACTS
Impacts to water resources in the project area are likely to result from activities
associated with project construction. Activities likely to result in impacts are clearing and
grubbing on streambanks, riparian canopy removal, instream construction, fertilizers
and pesticides used in revegetation, and pavement installation. The following impacts
to surface water resources are likely to result from the above mentioned construction
activities.
• Increased sedimentation and siltation downstream of the crossing and increased
erosion in the project area.
• Changes in light incidence and water clarity due to increased sedimentation and
vegetation removal.
• Alteration of water levels and flows due to interruptions and/or additions to surface
and ground water flow from construction.
• Changes in and destabilization of water temperature due to vegetation removal.
8
• Increased potential for release of toxic compounds such as fuel and oil from
construction equipment and other vehicles.
• Alteration of stream discharge due to silt loading and changes in surface and
groundwater drainage patterns.
In order to minimize potential impacts to water resources in the project area,
NCDOT's Best Management Practices for the Protection of Surface Waters will be
strictly enforced during the construction phase of the project. Limiting instream activities
and revegetating stream banks immediately following the completion of grading can
further reduce impacts.
3.0 BIOTIC RESOURCES
Biotic resources include terrestrial and aquatic communities. This section
describes the biotic communities encountered in the project area, as well as the
relationships between fauna and flora within these communities. The composition and
distribution of biotic communities throughout the project area are reflective of
topography, soils, hydrology, and past and present land uses. These classifications
follow Schafale and Weakley (1990) where possible. Representative animal species
that are likely to occur in these habitats (based on published range distributions) are
also cited.
Scientific nomenclature and common names (when applicable) are provided for
each animal and plant species described. Subsequent references to the same
organism refer to the common name only. Fauna observed during the site visit is
denoted in the text with an asterisk (*).
3.1 TERRESTRIAL COMMUNITIES
Descriptions of the two terrestrial systems are presented in the context of plant
community classifications. Terrestrial wildlife relationships are discussed after the two
terrestrial community descriptions.
3.1.1 Disturbed/maintained roadside community
This community is located on both sides of SR 1147 and may be impacted by
alternatives 1 and 2. Because of mowing and the use of herbicides this community is
kept in a constant state of early succession. The ground cover of this community is
composed of several species of herbaceous grasses and weeds, these include:
common chickweed (Stellaria media), wild ginger (Asarum canadense), star toadflax
(Comandra umbellata), field sorrel (Rumex acetosella), corn salad (Valerianella olitoria),
viola (Viola sp.), wild geranium (Geranium maculatum), purple dead nettle (Lamium
9
purpureum), panic grass (Panicum sp.), milkweed (Asclepias sp.), ragweed (Ambrosia
artemisifolia), wood sorrel (Oxalis sp.), red clover (Trifolium pratense), thistle (Carduus
sp.), beggar's tick (Bidens sp.), plantain (Plantago sp.), vaseygrass (Paspalum sp.),
wingstem (Actinomeris alternifolia), and bluegrass (Poa sp.). Vines that occupy these
areas include, swamp rose (Rosa sp.), Virginia creeper (Parthenocissus quinquefolia),
trumpet vine (Campsis radicans), Japanese honeysuckle (Lonicera japonica), and
blackberry (Rubus sp.). Often, the duration between maintenance sessions of highway
right-of-ways is quite long, allowing time for larger herbaceous shrubs and woody
vegetation to inhabit this disturbed area. Some of these herbaceous shrubs and woody
vegetation that may inhabit this disturbed community include: sweet gum (Liquidambar
styraciflua), red maple (Acer rubrum), tulip poplar (Lirodendron tulipifera), black cherry
(Prunus serotina), loblolly pine (Pious taeda), black walnut (Juglans nigra), evening
primrose (Oenothera biennis), and smooth sumac (Rhus glabra).
3.1.2 Riparian Forest
This community is located on both sides of South Potts Creek on either side of
SR 1147. It is adjacent to the maintained/disturbed roadside community. The portion of
this community on the north side of the creek is within a narrow floodplain of South
Potts Creek and is at a higher elevation than the south bank. The soil in this area is
well-drained sandy loam composed of alluvial deposits from floodwaters. This area
receives infrequent floodwaters from South Potts Creek resulting in temporary
inundation. The soil composition and the topography of this narrow floodplain causes
the floodwaters to quickly drain back into the creek. It did not appear that flooding in this
area was frequent. Vegetation in this community is adapted to periodic flood conditions
and soils that are exposed to runoff flowing into the adjacent creek. The canopy layer in
this community is comprised of black walnut (Juglans nigra), sweet gum, river birch
(Betula nigra), and tulip poplar. The sub-canopy is comprised of ironwood (Carpinus
caroliniana), witch hazel (Hamamelis virginiana), dogwood (Comus alterniflora),
Chinese privot (Ligustrum sinense), and silky dogwood (Comus amomum). Box elder
(Acernegunda), and green ash (Fraxinus pennsylvanica) are found right along the bank
of the creek. The groundcover in this community is comprised of various herbs and
grasses including Japanese grass, wingstem, solidago (Solidago sp.), giant cane
(Arundinaria gigantea), and Christmas fern (Polystichium acrosticoides). Vines found in
this community where Japanese honeysuckle, and blackberry. The south side of the
creek is at a lower elevation and is on the inside of the creek bend. The vegetation
represented on the south side of the creek was the same as on the north side. Part of
the riparian community has been converted to a pasture area for farm animals to graze
in. This area was approximately 30 to 50 ft from the creek bank and was fenced in so
the animals could not reach the creek.
10
.3.1.4 Terrestrial Wildlife
The disturbed/maintained roadside and agricultural fields adjacent to forested
tracts provide rich ecotones for foraging, while the forests provide forage areas and
cover. Birds that are often associated with ecotones between these communities are
ruby-crowned kinglet (Regulus calendula), Carolina chickadee (Parus carolinensis)*,
bluebird (Sialia sialis), downy woodpecker (Picoides pubescens), yellow-throated
warbler (Dendroica dominica), blue-gray gnatcatcher (Polioptila caerulea), white-
breasted nuthatch (Sitta carolinensis), northern cardinal (Cardinalis cardinalis)*, ruby-
throated hummingbird (Archilochus colubris), indigo bunting (Passerine cyanea),
yellow-billed cuckoo (Coccyzus americanus), blue jay (Cyanocitta cristata)*, tuffed
titmouse (Parus bicolor)*, acadian flycatcher (Empidonax traillii), and mourning dove
(Zenaida macroura)*. The red-tailed hawk (Bueto jamaicensis) is a major predator in
this habitat, feeding on small mammals, reptiles, and amphibians.
Small mammals may inhabit these early successional habitats along forested
areas, roadsides, and streams for nesting and feeding. Some of these small mammals
include, woodchuck (Marmots monax), white-footed mouse (Peromyscus leucopus),
least shrew (Crypototis parva), southern short-tailed shrew (Blaring carolinensis), hispid
cottonrat (Sigmodon hispidus), and eastern cottontail rabbit (Sylvilagus f/oridanus).
Larger mammals that may be present in these habitat areas for foraging,
feeding, watering, bedding, and mating include: raccoon (Procyon lotor), white-tailed
deer (Odocoilus virginiana), opossum (Didelphis virginiana), eastern gray squirrel
(Sciurus carolinensis)*, red fox (Vulpes vulpes), and gray fox (Urocyon
cinereoargenteus).
Reptiles and amphibians that may inhabit these community types include, queen
snake (Regina septenvittata), black rat snake (Elaphe obsoleta), copperhead
(Aghistrodon contortrix), garter snake (Thamnophis sirtalis), American toad (Bufo
americanus), Fowler's toad (Bufo woodhoush), fence lizard (Sceloporus undulatus), and
five-lined skink (Eumeces laticeps).
3.2 AQUATIC COMMUNITY
This community consists of South Potts Creek. Research has shown that a large
amount of food chain energy of stream communities is derived from allochthonous
(produced outside the river ecosystem) sources, in the form of terrestrial detritus.
Rocks, fallen debris (logs, sticks, etc.), and low velocity areas in the river trap detritus
within the river. The detritus is then decomposed by heterotrophic microorganisms,
such as bacteria and consumed by macroinvertebrates, such as aquatic insects. In
turn, the aquatic insects are then consumed by larger organisms. The amount of
allochthonous energy input within a river varies seasonally. Autochthonous (produced
11
within the river ecosystem) energy sources include planktonic and benthic micro and
macro algae as well as aquatic vascular vegetation. Fallen logs in the water and rock
surfaces offer an attachment substrate for algae.
Aquatic insects that may be found in this community include the water strider
(Gerris spp.), water beetle (Dytiscidae), stonefly (Plecoptera), dragonfly (Odonata),
cranefly (Tipula spp.), caddisfly (Trichoptera), stream mayfly (Ephemeroptera) and
black-winged damselfly (Calopteryx maculata).
Aquatic insects found in this community may be eaten by gamefish and other
fishes that may occur in South Potts Creek and the tributary. Gamefish such as chain
pickeral (Esox nigra), and sunfishes (Lepomis spp.) may occupy these tributaries.
Other fishes, such as shiners (Notropis spp.), golden shiners (Notemigonus
crysoleucas), eastern mosquitofish (Gambusia affinis), darters (Etheostoma spp.),
chubs (Semotilus spp.), daces (Clinostomus spp.), and catfishes (Ictaluridae) may
occupy this tributary, as well.
Several other animals representing all vertebrate classes are integral parts of the
aquatic system. The northern dusky salamander (Desmognathus fuscus) and the two-
lined salamander (Eurycea bislineata) may occur under rocks and logs within the
riverbed. Frogs, such as pickeral frog (Rana palustris), upland chorus frog (Pseudacris
triseriata), southern leopard frog (Rana sphenocephala), and bullfrog (Rana
catesbeiana), may occur in this habitat along stream banks feeding on aquatic
invertebrates. Other reptiles and amphibians occurring in this habitat feeding on small
fish and mussels, may include, northern water snake (Nerodia sipedon) and snapping
turtle (Chelydra serpentina).
3.3 SUMMARY OF ANTICIPATED IMPACTS
Construction of the proposed project will have various impacts on the biotic
resources described. Any construction related activities in or near these resources have
the potential to impact biological functions. This section quantifies and qualifies
potential impacts to the natural communities within the project area in terms of the area
impacted and the organisms affected. Temporary and permanent impacts are
considered here as well, along with recommendations to minimize or eliminate impacts.
3.3.1 Terrestrial Impacts
Impacts to terrestrial communities will result from project construction due to the
clearing and paving of portions of the project area, and thus the loss of community
area. Table 2 summarizes potential losses to these communities, resulting from project
12
construction. Calculated impacts to terrestrial communities reflect the relative
abundance of each community present in the study area. Estimated impacts are
derived based on the project lengths described in section 1.1, and the entire proposed
right-of-way width of 18.2 m (60.0 ft) for the bridge replacement for alternate 1 and 2
and a proposed right-of-way width of 18.2 m (60 ft.) for the on-site detour. However,
project construction often does not require the entire right-of-way; therefore, actual
impacts may be considerably less.

*Permanent Impacts
**Temporary Impacts
3.3.2 Aquatic Impacts
Impacts to the aquatic communities of South Potts Creek will result from the
replacement of Bridge 404. Impacts are likely to result from the physical disturbance of
aquatic habitats (i.e. substrate and water quality). Disturbance of aquatic habitats has a
detrimental effect on aquatic community composition by reducing species diversity and
the overall quality of aquatic habitats. Physical alterations to aquatic habitats can result
in the following impacts to aquatic communities:
• Inhibition of plant growth.
• Algae blooms resulting from increased nutrient concentrations.
• Loss of benthic macroinvertebrates through scouring resulting from an increased
sediment load.
Impacts to aquatic communities can be minimized by strict adherence to Best
Management Practices (BMP's).
3.3.3 Natural resource recommendation for alternates
Natural resource issues should be major concerns during transportation
improvement project development. The proper alignment chosen will have variable
impacts on natural resources. From a natural resources perspective, alternate 1 is the
recommended and preferred alternate with the least natural resource impacts.
13
4.0 JURISDICTIONAL TOPICS
This section provides inventories and impact analyses pertinent to two significant
regulatory issues: Waters of the United States and rare and protected species. These
issues retain particular significance because of federal and state mandates that
regulate their protection. This section deals specifically with the impact analyses
required to satisfy regulatory authority prior to project construction.
4.1 WATERS OF THE UNITED STATES
Surface waters and wetlands fall under the broad category of "Waters of the
United States," as defined in Section 33 of the Code of Federal Register (CRF) Part
328.3. Any action that proposes to dredge or place fill material into surface waters or
wetlands falls under the jurisdiction of the U.S. Army Corps of Engineers (COE) under
Section 404 of the Clean Water Act (33 U.S.C. 1344). Surface waters include all
standing or flowing waters which have commercial or recreational value to the public.
Wetlands are identified based on the presence of hydric soils, hydrophytic vegetation,
and saturated or flooded conditions during all or part of the growing season.
4. 1.1 Characteristics of Wetlands and Surface Waters
Criteria to delineate jurisdictional wetlands include evidence of hydric soils,
hydrophytic vegetation and hydrology. There are no jurisdictional wetlands located
in the project area, therefore no wetland impacts will result from the construction
of this project. Impacts to jurisdictional surface waters are calculated based on the
linear feet of the stream that is located within the proposed right-of-way. Physical
aspects of surface waters are described in section 2.3.1. Impacts to jurisdictional
surface waters within in the project right-of-way could possibly impact, but not to
exceed, 60 linear feet of creek (proposed right-of-way) for alternate 1 and
alternate 2. The on-site detour possible impacts would not exceed 60 linear feet
of creek (proposed right-of-way).
4.1.2 Permits
Impacts to jurisdictional surface waters are anticipated from the proposed
project. As a result, construction activities will require permits and certifications from
various regulatory agencies in charge of protecting the water quality of public water
resources.
14
A Nationwide Permit 33 CFR 330.5(a) (23) is likely to be applicable for all
impacts to Waters of the United States resulting from the proposed project. This permit
authorizes activities undertaken, assisted, authorized, regulated, funded or financed in
whole, or part, by another Federal agency or department where that agency or
department has determined that pursuant to the council on environmental quality
regulation for implementing the procedural provisions of the National Environmental
Policy Act:
• (1) that the activity, work, or discharge is categorically excluded from environmental
documentation because it is included within a category of actions which neither
individually nor cumulatively have a significant effect on the human environment,
and;
• (2) that the office of the Chief of Engineers has been furnished notice of the agency'
or department's application for the categorical exclusion and concurs with that
determination.
This project will also require a 401 Water Quality Certification from the DWQ
prior to the issuance of the Nationwide Permit. Section 401 of the Clean Water Act
requires that the state issue or deny water certification for any federally permitted or
licensed activity that may result in a discharge to Waters of the United States. Section
401 Certification allows surface waters to be temporarily impacted for the duration of
the construction or other land manipulation. The issuance of a 401 permit from the
DWQ is a prerequisite to issuance of a Section 404 permit.
4.1.3 Avoidance, Minimization, Mitigation
The COE 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, specifically wetlands.
Mitigation of wetland impacts has been defined by the CEQ to include: avoiding impacts
(to wetlands), minimizing impacts, 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 COE,
in determining "appropriate and practicable" measures to offset unavoidable impacts,
such measures 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.
15
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 to median widths, right-of-way widths, fill slopes and/or road shoulder widths.
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. Appropriate and practicable
compensatory mitigation is required for unavoidable adverse impacts that remain after
all appropriate and practicable minimization has been required. Compensatory actions
often include restoration, creation and enhancement of Waters of the United States,
specifically wetlands. Such actions should be undertaken in areas adjacent to or
contiguous to the discharge site.
Compensatory mitigation is required for those projects authorized under
Nationwide Permits that result in the fill or alteration of:
• More than 0.04 ha (0.10 ac) of wetlands will require compensatory mitigation;
• And/or more than 45.7 m (150.0 linear ft) of streams will require compensatory
mitigation.
Written approval of the final mitigation plan is required from the DWQ prior to the
issuance of a 401 Certification. Final permit/mitigation decisions rest with the COE.
4.2 RARE AND PROTECTED SPECIES
Some populations of fauna and flora have been in, or are in, the process of
decline either due to natural forces or their inability to coexist with human development.
Federal law (under the provisions of the Endangered Species Act of 1973, as
amended) requires that any action, likely to adversely affect a species classified as
federally-protected, be subject to review by the United States Fish and Wildlife Service
(FWS). Other species may receive additional protection under separate state laws.
4.2.1 Federally-Protected Species
Plants and animals with federal classifications of Endangered (E), Threatened
(T), Proposed Endangered (PE), and Proposed Threatened (PT) are protected under
the provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as
amended. As of June 16, 2000, the FWS lists three species as federally-protected
for Davidson County. These species are listed in the table below with a brief
description of habitat and a biological conclusion following.
16
Table 3. Federally-protected species for Davidson County.
Corr mbri Name tatua
Clemmys muhlenbergii Bog turtle T(S/A)
Haliaeetus leucocephalus Bald Eagle Threatened
Helianthus schweinitzii Schweinitz's sunflower Endangered
• Endangered -a taxon "in danger of extinction throughout all or a significant portion
of its range."
• Threatened -a taxon "likely to become endangered within the foreseeable future
throughout all or a significant portion of its range."
• T(S/A) Threatened due to similarity of appearance
Name: Bog turtle (Clemmys muhlenbergi) Threatened (S/A)
Family: Emydidae
Federal Status: Threatened Due to Similarity of Appearance (southern population)
Date Listed: June 4, 1987
Characteristics:
The bog turtle is a small semi-aquatic reptile, measuring 7.5-11.4 cm in length,
with a weakly keeled, dark brown carapace and a blackish plastron with lighter
markings along the midline. There is a conspicuous orange or yellow blotch on each
side of the head. This species exhibits sexual dimorphism; the males have concave
plastrons and longer, thicker tails, while females have flat plastrons and shorter tails.
Distribution and Habitat:
The bog turtle is found in the eastern United States, in two distinct regions. The
northern population, in Massachussets, Connecticut, southern New York, New Jersey,
Pennsylvania, Maryland, and Delaware is listed as Threatened and protected by the
Endangered Species Act. The southern population, occurring in Virginia, North
Carolina, South Carolina, Tennessee, and Georgia is listed as Threatened Due to
Similarity of Appearance.
Preferred bog turtle habitat consists of fens, sphagnum bogs, swamps, marshy
meadows and pastures. Areas with clear, slow-flowing water, soft mud substrate, and
an open canopy are ideal. Clumps of vegetation such as tussock sedge and sphagnum
moss are important for cresting and basking. This species hibernates from October to
April, hiding just under the frozen surface of mud. The diet consists of beetles, moth
and butterfly larvae, caddisfly larvae, snails, nematodes, millipedes, seeds, and carrion
(Nemuras 1967).
Mating takes place in May and June, and the female deposits the clutch of 2-6
eggs in a sedge tussock, a clump of sphagnum moss, or loose soil about a month later.
The eggs hatch in 42-56 days. A female may not nest every year, and probably only
produces one clutch per reproductive year.
17
Threats to Species:
The primary threats to the bog turtle are loss of habitat (from increased
residential and commercial development as well as draining, clearing, and filling
wetlands) and illegal collecting for the pet trade. Nest predation and disease may also
play a role in the population decrease.
Distinctive Characteristics:
The bog turtle is distinguished from other turtles by its small size and the bright
orange or yellow blotch on each side of its head.
Haliaeetus leucocephalus (bald eagle) Threatened
Animal Family: Accipitridae
Date Listed: 3/11/67
Distribution in N.C.: Anson, Beaufort, Brunswick, Carteret, Chatham, Chowan,
Craven, Dare, Durham, Guilford, Hyde, Montgomery, New Hanover,
Northhampton, Periquimans, Richmond, Stanley, Vance, Wake,
Washington.
Adult bald eagles can be identified by their large white head and short white tail.
The body plumage is dark-brown to chocolate-brown in color. In flight bald eagles can
be identified by their flat wing soar.
Eagle nests are found in close proximity to water (within a half mile) with a clear
flight path to the water, in the largest living tree in an area, and having an open view of
the surrounding land. Human disturbance can cause an eagle to abandon otherwise
suitable habitat. The breeding season for the bald eagle begins in December or January.
Fish are the major food source for bald eagles. Other sources include coots, herons,
and wounded ducks. Food may be live or carrion.
Biological Conclusion: No Effect
Within the project vicinity there is no suitable nesting or foraging habitat for the
bald eagle. It can be concluded that the construction of this project will not effect this
species.
18
Helianthus schweinitzii (Schweinitz's sunflower) Endangered
Plant Family: Asteraceae
Federally Listed: June 6, 1991
Flowers Present: mid September-early October
Distribution in N.C.: Cabarrus, Davidson, Mecklenburg, Montgomery, Randolph,
Rowan, Stanly, Stokes, Union.
Schweinitz's sunflower is a rhizomatous perennial herb that grows 1-2 m tall from
a cluster of carrot-like tubrous roots. The stems are deep red, solitary and only branch
above mid-stem. The leaves are rough feeling above and resin-dotted and loosely soft-
white-hairy beneath. Leaves of the sunflower are opposite on the lower part of the stem
and usually become alternate on the upper stem. The broad flowers are borne from
September until frost. These flowers are yellow in color and arranged in an open system
of upwardly arching heads. The fruit is a smooth, gray-black achene.
Schweinitz's sunflower is endemic to North and South Carolina. These
sunflowers grow best in full sunlight or light shade in clearings and along the edges of
open stands of oak-pine-hickory upland woods. Common soils that this species is
found in are moist to dryish clays, clay-loams, or sandy clay-loams, often with a high
gravel content and always moderately podzolized. Natural fires and large herbivores
are considered to be historically important in maintaining open habitat for these
sunflowers.
Biological Conclusion: Unresolved
There is suitable habitat within the project vicinity along the roadside for this
species. A survey will need to be conducted for this species and concurrence from the
USFWS after the survey is performed will need to be received.
4.2.2 Federal Species of Concern and State Listed Species
Federal species of concern are not afforded federal protection under the
Endangered Species Act and are not subject to any of its provisions, including Section
7, until they are formally proposed or listed as Threatened or Endangered. However,
the status of these species is subject to change, and so should be included for
consideration. Federal Species of Concern (FSC) are defined as a species that is under
consideration for listing for which there is insufficient information to support listing. In
addition, organisms which are listed as Endangered (E), Threatened (T), or Special
Concern (SC) by the North Carolina Natural Heritage Program list of Rare Plant and
Animal Species are afforded state protection under the NC State Endangered Species
Act and the NC Plant Protection and Conservation Act of 1979. There are two federal
species of concern listed by the FWS for Davidson County. (Table 4)
19
Table 4. Federal Species of Concern for Davidson County.
Scientific Name Common Name NC Status Habitat
Etheostoma collis Carolina darter SC Present
Lotus helleri Heller's trefoil C Present
"SC"-Any species of wild animal native or once-native to North Carolina which is
determined by the Wildlife Resources Commission to require monitoring but which
may be taken under regulations adopted under the provisions of this article. (Article
25 of Chapter 113 of the General Statutes; 1987).
"C"--A Candidate species is one which is very rare in North Carolina, generally with
1-20 populations in the state, generally substantially reduced in numbers by habitat
destruction, direct exploitation or disease. The species is also either rare throughout
its range or disjunct in North Carolina from a main range in a different part of the
country or the world.
A review of the NCNHP database of rare species and unique habitats shows no
occurrences of rare species within the project vicinity.

Subject: Federally protected plant surveys for Schweinitz's Sunflower (Helianthus
schweinitzii). This is for the proposed bridge replacement of bridge # 404 on SR 1147
over South Potts Creek in Davidson County. TIP No. B-4334, State Project No.
8.2604401; Federal Aid No. BRSTP-1147(3).
Reference: Natural Resources Technical Report (NCDOT, January 22, 2001)
The subject project involves the replacement of Bridge No. 404 on SR 1147 in
Davidson County. This memo addresses a federally-protected species issue for the above
mentioned project. A biological conclusion of unresolved was issued for Schweinitz's
Sunflower in the Natural Resources Technical Report for this project. Schweinitz's
Sunflower is listed as a endangered species in Davidson county by the U.S. Fish and
Wildlife Service. A description of these species is presented in the Natural Resources
Technical Report.
Habitat for Schweinitz's Sunflower does exist in the project area in the form of
maintained roadside shoulders. A plant-by-plant survey was conducted on September 26,
2001 by NCDOT biologist Lindsey Riddick and Clay Willis to determine if this species is
located in the project area. The surveyed area included both shoulders of the roadway for
the entire length of the project, which is about 500 feet. This survey was conducted for
approximately 30 minutes. Schwientiz's Sunflower was not observed to occur within the
project area.
In addition to this survey Natural Heritage Program (NHP) files were reviewed on
September 20, 2001 for any recorded observations of Schwienitz's Sunflower within the
project area. The NHP had no records of this species being sited in the project area or
within a mile of the project area boundaries.
It can be concluded that this federally-protected species will not be effected by the
construction of this project.
Biological Conclusion:
No Effect

Stream >btaia flora for Tributary to South Pots Creek
Currently, this tributary tneaudcrs around the existing interior bents of the existing
bridge. The interior bents of the new stream will impact the existing dream. Therefore it
was decided too perruaneady+ rolocr?te the stream to avoid the intearlor !ridge bent.
The strebro relocation for the tributary to South Potts Crock wa3 designed to match the
cisqrag stream cross section and slope. The existing stream hat a cross scotiortal anew of
35 R`. The proposed stream has a aross sectional area of 42 a The area is slightly larger
because we used 3: t side slopes for the proposed stream. Coir fiber matting will be used
to sabili= the side dopes of the stream relocation. TU 51 base width of the proposed
stream rnatelies the existing. I'm depth of 3 feet for the proposed stream is the ulna as
the existing since the stream is being relocated through the floodplain of South Potts
Creek. The drainage am of the stream is 3.63 sq. mi. Using Manning equation for the
open channel hydraulics for a stream section with a 5' base, 3:1 side slopes, 3' deep with
it slope of L W19 yields a discharge of 210 efa with a velocity of 5.0 ft/see, The 2yr
discharge Calculated using the U'SGS Report 01-4207 for the Rural Blue Ridge-Piedmont
region yields a discharge of 330 ft/sec.
