Replacement of Bridge No. 42 on SR 1002 (Cabarrus Avenue) over Three Mile Branch
APPROVAL of 401 Water Quality Certification with Additional Conditions, WRP
Mr. Gregory J. Thorpe, Ph.D., Manager
NCDOT Project Development & Environmental Analysis
1548 Mail Service Center
Raleigh, NC 27699-1548
Dear Dr. Thorpe:
You have our approval, in accordance with the attached conditions and those listed below, incur the
following impacts:
¦ 0.044 acres of wetlands;
¦ 225 linear feet of jurisdictional streams.
These impacts are necessary to replace Bridge No. 42 on SR 1002 (Cabarrus Avenue) over Three Mile
Branch. The project should be constructed in accordance with your application dated June 30, 2003 and
subsequent information dated September 9, 2003.
After reviewing your application, we have decided that this fill is covered by General Water Quality
Certification No. 3403 corresponding to the U.S. Army Corps of Engineers Nationwide Permit Number
23. In addition, you should acquire and comply with any other federal, state or local permits before you
proceed with your project including (but not limited to) Sediment and Erosion Control, and Non-
Discharge as well as the Water Supply Watershed regulations. This approval will expire with the
accompanying 404 permit unless otherwise specified in the Water Quality Certification.
This approval is only valid for the purpose and design that you described in your application except as
modified below. If you change your project, you must notify us, in writing, and send us a new
application. If the property is sold, the new owner must be given a copy of this Certification and approval
letter and is thereby responsible for complying with all conditions. If total wetland fills for this project
(now or in the future) exceed one acre, or if stream impacts exceed 150 linear feet, compensatory
mitigation may be required as described in 15A NCAC 211.0506 (h) (6) and (7). For this approval to be
valid, you must follow the conditions listed in the attached certification and any additional conditions
listed below.
1. Riparian vegetation must be reestablished within the construction limits of the project by the end
of the growing season following completion of construction.
2. The culverts shall be designed and installed to allow for fish and other wildlife movement as well
as prevent headcutting of the streams.
3. Use of rip-rap for bank stabilization is to be minimized; rather, native vegetation is to be planted
when practical. If rip-rap is necessary, it must be limited to the stream bank below the high water
mark, and vegetation must be used for stabilization above high water. Rip rap shall not be placed
in the stream bottom.
4. Compensatory Mitigation: The NC DENR Wetlands Restoration Program (WRP) will
assume responsibility for satisfying the compensatory mitigation requirements for this
project. Until the Wetland Restoration Program receives and clears your check,

impacts to the on-site stream shall not occur. You have two months from the date of
this Certification to make the payment.
Upon completion of the project, the NCDOT shall complete and return the enclosed
"Certificate of Completion" form to notify NCDWQ when all work included in the
§401 Certification has been completed. The responsible party shall complete the
attached form and return it to the 40l/Wetlands Unit of the NC Division of Water
Quality upon completion of the project. Please include photographs upstream and
downstream of the structure to document correct installation.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing.
You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written
petition that conforms to Chapter 150B of the North Carolina General Statutes to the Office of
Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its
conditions are final and binding unless you ask for a hearing.

Please reference the June 30, 2003 application for a Nationwide Permit 23 submitted for
the above referenced project. In the original application, the NCDOT proposed a
combination of compensatory mitigation that included utilizing both the Afton Run
Mitigation Site in Cabarrus County as well as the North Carolina Wetland Restoration
Program (WRP). Since that time the North Carolina Division of Water Quality has
objected to utilizing the Afton Run Mitigation site. Therefore, the NCDOT hereby
rescinds the proposal to utilize the Afton Run Mitigation site and proposes to provide the
total balance of mitigation, 450.0 linear feet, through the in lieu fee program of the WRP.
A copy of the original application is attached for your concurrence.
It is anticipated that this action will be authorized by a Nationwide Permit 23 (FR number
10, pages 2020-2095; January 15, 2002). As we stated in our original application, we
anticipate 401 General Certification number 3361 will apply to this project. 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). In accordance with

Re: Supplemental Request for Mitigation for the Proposed Replacement of Bridge No.

SUBJECT: Nationwide Permit 23 Application for the proposed replacement of
Bridge No. 42 on SR 1002 (Cabanus Avenue) over Three Mile
Branch, Cabanas County. Federal Aid Project No. BRSTP-1002(5),
State Project No. 8.266320 1, TIP No. B-3422.
The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge
No. 42 over Three Mile Branch (DWQ Index 13-17-9-4-5), a Division of Water Quality
(DWQ) Class "C" Waters of the State. The project involves replacing the current bridge
with a double barrel (2 @ 13-feet wide by 12-feet high) reinforced concrete box culvert
(Please note that the 2 barrel design has replaced the 3 barrel design stated in the CE).
This structure will be of sufficient length to allow the road to be widened to
accommodate three 12-foot travel lanes with 11-foot shoulders on each side. Four feet of
each shoulder will be paved. A separate single barrel, 8-foot wide by 8-foot high
reinforced concrete box culvert will be constructed just west of Three Mile Branch to
provide for a future City of Concord greenway trail. Improvements to the approach
roadways (grading and clearing) will be required for a distance of approximately 275 feet
to the west and 350 feet to the east of the structure. Traffic will be detoured offshe
during construction.
R"ACTS TO WATERS OF THE UNITED STATES
The topography surrounding the existing bridge and roadway is very steep. Much of the
existing slope is covered with rip rap to prevent erosion. As part of the construction of
the culvert, the fill slopes will extend beyond the culvert wing walls and will also require
rip rap to prevent erosion of the banks. As a result, the loss of channel is being calculated
from one end of the rip rap fill slope, through the culvert, to the other end of the rip rap

fill slope, a total of 225 linear feet. A total of 0.044 acre of surface waters will also be
lost when the culvert is placed in the stream. Due to the small size of Three Mile Branch,
no temporary surface water fill for construction access is anticipated. No jurisdictional
wetlands will be affected by the proposed project..
BRIDGE DEMOLITION
NCDOT and all potential contractors will adhere to Best Management Practices for
"Bridge Demolition and Removal" during the removal of bridge 42. Bridge No. 42 is a
three-span structure that consists of pre-cast, pre-stressed concrete channels with an
asphalt wearing surface. The overall length of the structure is 91 feet and the clear
roadway width over the structure is 24 feet. End bents consist of reinforced concrete caps
on timber piles with timber bulkheads and interior bents of reinforced concrete caps on
timber piles. It is anticipated that the bridge will be removed without dropping any
components into the water, however there is the potential that portions of the
superstructure could fall into the river. In this unlikely scenario, the resulting potential
temporary fill would be less than 10 cubic yards.
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 29 January, 2003
the Fish and Wildlife Service (FWS) lists two federally protected species for Cabarrus
County, Carolina heelsplitter (Lasmigona decorata) and Schweinitz's sunflower
(Helianthus schweinitzit).
On June 20, 2003, Tom Dickinson of The Catena Group, Inc. visited the project site to
update protected issues and evaluate potential habitat for the Carolina heelsplitter and
Schweinitz's sunflower. The existing stream is severely degraded, confirming that the
Biological Conclusion of no effect, based on lack of suitable habitat, is valid for the
Carolina heelsplitter. The man dominated community described in the CE was also
evaluated for suitable habitat for Schweinitz's sunflower. Now that the project limits
have been established, it is apparent that there is no suitable habitat within the area of
impact. Therefore, it has been concluded that suitable habitat is not present for
Schweinitz's sunflower and therefore, a Biological Conclusion of no effect has been
rendered for this species.
MITIGATION OPTIONS
As part of the efforts to avoid and minimize jurisdictional impacts, the length of the
culvert is the minimum necessary to accommodate the roadway widening. This will
leave as much surface water as possible "daylighted", though the rip rap fill slopes will
have to extend beyond the culvert, along the banks.
In another minimization effort, a low flow channel will be constructed within one of the
barrels of the culverts, as detailed in sheet 6 of 6 of the permit drawings.
After the avoidance and minimization efforts, the project will still impact 225 linear feet
of existing channel. Three Mile Branch is in the Yadkin-Pee Dee River Basin,
Cataloging Unit 03040105. NCDOT is proposing to provide mitigation through a
combination of in lieu payments to the Wetland Restoration Program (WRP) and the
Afton Run Mitigation site in Cabarrus County. The NCDOT will debit 261.0 linear feet
of stream restoration from the Afton Run site. The remaining balance (utilizing a 2:1
ratio to provide 450.0 linear feet of stream mitigation) of 189.0 feet will be provided
through a payment in the amount of $23,625.00 (189.0 x 2 x $125/ft) to the WRP. A
payment in the amount of $23, 625 will be forwarded to WRP upon receipt of the
requested permits.
SUMMARY
It is anticipated that this action will be authorized by a Nationwide Permit 23 FAR number
10, pages 2020-2095; January 15, 2002). We anticipate 401 General Certification number
3361 will apply to this project. 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). In accordance with 15A NCAC 211.0501 (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.
Thank you for your assistance with this project. If you have any questions or need

County. Federal Aid Project No. BRSTP-1002(5), State Project No.
8.2663201, TIP No. B-3422.; DWQ Project No. 030815
Please reference the June 30, 2003 application for a Nationwide Permit 23 submitted for
the above referenced project. In the original application, the NCDOT proposed a
combination of compensatory mitigation that included utilizing both the Afton Run
Mitigation Site in Cabarrus County as well as the North Carolina Wetland Restoration
Program (WRP). Since that time the North Carolina Division of Water Quality has
objected to utilizing the Afton Run Mitigation site. Therefore, the NCDOT hereby
rescinds the proposal to utilize the Afton Run Mitigation site and proposes to provide the
total balance of mitigation, 450.0 linear feet, through the in lieu fee program of the WRP.
A copy of the original application is attached for your concurrence.
It is anticipated that this action will be authorized by a Nationwide Permit 23 (FR number
10, pages 2020-2095; January 15, 2002). As we stated in our original application, we
anticipate 401 General Certification number 3361 will apply to this project. 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). 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.

Re: Supplemental Request for Mitigation for the Proposed Replacement of Bridge No.
42 on SR 1002 (Cabarrus Avenue) over Three Mile Creek in Cabarrus County,
North Carolina.
Dear Mr. Ferrell:
The North Carolina Department of Transportation (NCDOT) requests that the Wetland
Restoration Program (WRP) perform stream mitigation for the proposed bridge
replacement in Cabarrus County, North Carolina. An original request for 190.0 linear
feet of stream mitigation was submitted on June 26, 2003. This request includes an
additional 260.0 feet, for a total of 450.0 linear feet.
Stream impacts for the project are 225.0 ft. in Hydrologic Unit 03040105 of the Yadkin
River Basin. These impacts require (2:1) mitigation totaling 450.0 ft. to satisfy
permitting requirements of the U.S. Army Corps of Engineers (USACE) and the North
Carolina Division of Water Quality (DWQ).
To facilitate review, the following table summarizes impacts and requested mitigation.

Dear Sir:
LYNDo TIPPETT
SECRETARY
SUBJECT: Nationwide Permit 23 Application for the proposed replacement of
Bridge No. 42 on SR 1002 (Cabanas Avenue) over Three Mile
Branch, Cabarrus County. Federal Aid Project No. BRSTP-1002(5),
State Project No. 8.2663201, TIP No. B-3422.
The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge
No. 42 over Three Mile Branch (DWQ Index 13-17-9-4-5), a Division of Water Quality
(DWQ) Class "C" Waters of the State. The project involves replacing the current bridge
with a double barrel (2 @ 13-feet wide by 12-feet high) reinforced concrete box culvert
(Please note that the 2 barrel design has replaced the 3 barrel design stated in the CE).
This structure will be of sufficient length to allow the road to be widened to
accommodate three 12-foot travel lanes with 11-foot shoulders on each side. Four feet of
each shoulder will be paved. A separate single barrel, 8-foot wide by 8-foot high
reinforced concrete box culvert will be constructed just west of Three Mile Branch to
provide for a future City of Concord greenway trail. Improvements to the approach
roadways (grading and clearing) will be required for a distance of approximately 275 feet
to the west and 350 feet to the east of the structure. Traffic will be detoured offsite
during construction.
IMPACTS TO WATERS OF THE UNITED STATES
The topography surrounding the existing bridge and roadway is very steep. Much of the
existing slope is covered with rip rap to prevent erosion. As part of the construction of
the culvert, the fill slopes will extend beyond the culvert wing walls and will also require
rip rap to prevent erosion of the banks. As a result, the loss of channel is being calculated
from one end of the rip rap fill slope, through the culvert, to the other end of the rip rap

fill slope, a total of 225 linear feet. A total of 0.044 acre of surface waters will also be
lost when the culvert is placed in the stream. Due to the small size of Three Mile Branch,
no temporary surface water fill for construction access is anticipated. No jurisdictional
wetlands will be affected by the proposed project.
BRIDGE DEMOLITION
NCDOT and all potential contractors will adhere to Best Management Practices for
"Bridge Demolition and Removal" during the removal of bridge 42. Bridge No. 42 is a
three-span structure that consists of pre-cast, pre-stressed concrete channels with an
asphalt wearing surface. The overall length of the structure is 91 feet and the clear
roadway width over the structure is 24 feet. End bents consist of reinforced concrete caps
on timber piles with timber bulkheads and interior bents of reinforced concrete caps on
timber piles. It is anticipated that the bridge will be removed without dropping any
components into the water, however there is the potential that portions of the
superstructure could fall into the river. In this unlikely scenario, the resulting potential
temporary fill would be less than 10 cubic yards.
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 29 January, 2003
the Fish and Wildlife Service (FWS) lists two federally protected species for Cabarrus
County, Carolina heelsplitter (Lasmigona decorata) and Schweinitz's sunflower
(Helianthus schweinitzii).
On June 20, 2003, Tom Dickinson of The Catena Group, Inc. visited the project site to
update protected issues and evaluate potential habitat for the Carolina heelsplitter and
Schweinitz's sunflower. The existing stream is severely degraded, confirming that the
Biological Conclusion of no effect, based on lack of suitable habitat, is valid for the
Carolina heelsplitter. The man dominated community described in the CE was also
evaluated for suitable habitat for Schweinitz's sunflower. Now that the project limits
have been established, it is apparent that there is no suitable habitat within the area of
impact. Therefore, it has been concluded that suitable habitat is not present for
Schweinitz's sunflower and therefore, a Biological Conclusion of no effect has been
rendered for this species.
MITIGATION OPTIONS
As part of the efforts to avoid and minimize jurisdictional impacts, the length of the
culvert is the minimum necessary to accommodate the roadway widening. This will
leave as much surface water as possible "daylighted", though the rip rap fill slopes will
have to extend beyond the culvert, along the banks.
In another minimization effort, a low flow channel will be constructed within one of the
barrels of the culverts, as detailed in sheet 6 of 6 of the permit drawings.
After the avoidance and minimization efforts, the project will still impact 225 linear feet
of existing channel. Three Mile Branch is in the Yadkin-Pee Dee River Basin,
Cataloging Unit 03040105. NCDOT is proposing to provide mitigation through a
combination of in lieu payments to the Wetland Restoration Program (WRP) and the
Afton Run Mitigation site in Cabarrus County. The NCDOT will debit 261.0 linear feet
of stream restoration from the Afton Run site. The remaining balance (utilizing a 2:1
ratio to provide 450.0 linear feet of stream mitigation) of 189.0 feet will be provided
through a payment in the amount of $23,625.00 (189.0 x 2 x $125/ft) to the WRP. A
payment in the amount of $23, 625 will be forwarded to WRP upon receipt of the
requested permits.
SUMMARY
It is anticipated that this action will be authorized by a Nationwide Permit 23 (FR number
10, pages 2020-2095; January 15, 2002). We anticipate 401 General Certification number
3361 will apply to this project. All other aspects of this project are being processed by
the Federal Highway Administration as a "Categorical Exclusion" in accordance with 23

Habitat Conservation Program, NCWRC
DATE: August 25, 2003
SUBJECT: Review of a Section 404 Permit application by NCDOT to replace Bridge No. 42
over Three Mile Branch on SR 1002 (Cabarrus Avenue), Cabarrus County. TIP
No. B-3422.
North Carolina Department of Transportation (NCDOT) has submitted a Section 404
application to the U.S. Army Corps of Engineers (USACE). Staff biologists with the North
Carolina Wildlife Resources Commission (NCWRC) have reviewed the information provided.
These comments are provided in accordance with the provisions of the National Environmental
Policy Act (42 U.S.C. 4332(2)(c)) and the Fish and Wildlife Coordination Act (48 Stat. 401, as
amended; 16 U.S.C. 661-667d).
The NCDOT proposes to replace Bridge No. 42 over Three Mile Branch on SR 1002
(Cabarrus Avenue) with a double barrel (2 @ 13-feet wide by 12-feet high) reinforced concrete
box culvert. A low flow channel will be constructed within one of the barrels. While we support
this effort, the culvert design needs to be re-evaluated to ensure it will function properly after the
floor of the culvert is buried one foot, as required for culvert installations. Permanent channel
impacts total 225 linear feet, including rip rap impacts. Mitigation is proposed as a combination
of in lieu payments to the Wetland Restoration Program and the Afton Run mitigation site in
Cabarrus County. In addition, a separate single barrel culvert will be constructed just west of
Three Mile Branch to provide for a future City of Concord greenway trail. We support
NCDOT's efforts to work with the community to provide safe public access and passage along
greenway trails.
Three Mile Branch is Class "C" waters. The Carolina creekshell (Villosa vaughaniana),

Bridge No. 42, SR 1002
Three Mile Branch, Cabarrus Co. 2 August 25, 2003
Significantly Rare, and Carolina darter (Etheostoma collis), Federal Species of Concern and state
Special Concern, have the potential to occur in the area, however the stream is severely
degraded. A cursory search during NCDOT's site investigation in 1998 found no signs of
aquatic life, a brown colored foam in places on the water surface and sewer line odors detectable
near the stream. The banks were eroded and no trees were along the stream in the project area.
Some of the rocks used for stabilization were in the streambed. NCDOT plans to stabilize the
stream banks and slopes using rip rap.
We recommend that NCDOT investigate natural alternatives to rip rap for bank
stabilization above the high-water mark in riparian areas and work with the City of Concord to
re-establish the riparian zone using native plantings that would be appropriate for a greenway
setting. They should also work with the city or county to correct any problems with the sewer
lines that could pose health risks to workers or the public in the project area.
In addition, we can concur with the permit issuance if the following conditions are
implemented:
1. Stringent sedimentation and erosion control measures must be implemented and
maintained on the project site until project completion to avoid impacts to downstream
aquatic resources. Temporary or permanent herbaceous vegetation should be planted on
all bare soil within 15 days of ground disturbing activities to provide long-term erosion
control. Tall fescue should not be permitted in riparian areas. Erosion control matting
should be used in riparian areas, instead of straw mulch and well anchored with 12"
staples or 12" wooden survey stakes.
2. Discharge of materials into the stream from demolition of old bridges should be avoided
as much as practicable. Any materials that inadvertently reach the stream should be
removed.
3. Culverts that are 48-inch diameter or larger should be placed with the floor of the barrel
approximately 12 inches below the stream bottom to allow natural stream bottom
materials to become established in the culvert following installation and to provide
aquatic life passage during periods of low flow. This may require increasing the size of
the culvert to meet flow conveyance requirements. These measurements must be based
on natural thalweg depths.
4. Culverts should be designed so that one barrel, of adequate size, will carry the base flow,
and the others will carry stormwater. Barrels other than the base flow barrel should be
placed on or near bankfull or floodplain bench elevation (similar to Lyonsfield design).
This may be accomplished by utilizing sills on the upstream end to restrict or divert flow
to the base flow barrel.
5. The design of sills and baffles must be compatible with recommendations 3 and 4 above.
Bridge No. 42, SR 1002
Three Mile Branch, Cabarrus Co. 3 August 25, 2003
6. The natural dimension, pattern, and profile of the stream above and below the crossing
should not be modified by widening the stream channel or changing the depth of the
stream.
7. Removal of vegetation in riparian areas should be minimized. Native trees and shrubs
should be planted along the stream banks to reestablish the riparian zone and to provide
long-term erosion control.
8. Grading and backfilling should be minimized, and tree and shrub growth should be
retained if possible to ensure long term availability of shoreline cover for fish and
wildlife. Backfill materials should be obtained from upland sites.
9. Riprap should be minimized and installed in a manner so as not to interfere with aquatic
life passage during low flow conditions. Riprap placed for bank stabilization should be
limited to the stream bank below the high water mark, and vegetation should be used for
stabilization above the high water elevation.
10. Stormwater, should be directed to buffer areas or retention basins and should not be
routed directly into streams.
11. If concrete will be used during construction, work must be accomplished so that wet
(uncured) concrete does not contact surface waters. This will lessen the chance of
altering the water chemistry and causing a fish kill.
12. Discharging hydroseeding mixtures and washing out hydroseeders and other equipment
in or adjacent to surface waters is strictly prohibited.
13. Heavy equipment should be operated from the bank rather than in the stream channel
whenever possible in order to minimize sedimentation and reduce the likelihood of
introducing other pollutants into the stream. All mechanized equipment operated near
surface waters should be inspected and maintained regularly to prevent contamination of
stream waters from fuels, lubricants, hydraulic fluids or other toxic materials.

Dear Mr. Thorpe:
The Division of Water Quality staff has reviewed your submittal for a §401 Water Quality
Certification for the aforementioned project received June 27, 2003 Review of the water
quality certification application revealed the following deficiency:
NCDOT proposes to use the Afton Run Site for compensatory stream mitigation.
Condition 3 of Water Quality Certification No. 3403 requires that mitigation plans be
submitted and approved in writing by DWQ before the impacts approved by the
Certification occur. Furthermore, the mitigation plan must be implemented and/or
constructed before the road is opened to the traveling public. Please submit plans for the
Afton Run Mitigation Site for approval or provide evidence that this site has been
approved and constructed.
Pursuant to 15A NCAC 2H.0507(a)(3), the permit application is placed on hold until we are supplied the
necessary information. Furthermore, until the information is received by the NC Division of Water
Quality, we request (by copy of this letter) that the US Army Corps of Engineers continue to place the
permit application on hold.
We look forward to working with you to expedite the processing of your permit application. If you have
any questions, please telephone Ms. Cynthia Van Der Wiele at 919.733.1786.

MS QUALITY SECTION
SUBJECT: Nationwide Permit 23 Application for the proposed replacement of
Bridge No. 42 on SR 1002 (Cabarrus Avenue) over Three Mile
Branch, Cabarrus County. Federal Aid Project No. BRSTP-1002(5),
State Project No. 8.2663201, TIP No. B-3422.
The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge
No. 42 over Three Mile Branch (DWQ Index 13-17-9-4-5), a Division of Water Quality
(DWQ) Class "C" Waters of the State. The project involves replacing the current bridge
with a double barrel (2 @ 13-feet wide by 12-feet high) reinforced concrete box culvert
(Please note that the 2 barrel design has replaced the 3 barrel design stated in the CE).
This structure will be of sufficient length to allow the road to be widened to
accommodate three 12-foot travel lanes with 11-foot shoulders on each side. Four feet of
each shoulder will be paved. A separate single barrel, 8-foot wide by 8-foot high
reinforced concrete box culvert will be constructed just west of Three Mile Branch to
provide for a future City of Concord greenway trail. Improvements to the approach
roadways (grading and clearing) will be required for a distance of approximately 275 feet
to the west and 350 feet to the east of the structure. Traffic will be detoured offsite
during construction.
IMPACTS TO WATERS OF THE UNITED STATES
The topography surrounding the existing bridge and roadway is very steep. Much of the
existing slope is covered with rip rap to prevent erosion. As part of the construction of
the culvert, the fill slopes will extend beyond the culvert wing walls and will also require
rip rap to prevent erosion of the banks. As a result, the loss of channel is being calculated
from one end of the rip rap fill slope, through the culvert, to the other end of the rip rap

fill slope, a total of 225 linear feet. A total of 0.044 acre of surface waters will also be
lost when the culvert is placed in the stream. Due to the small size of Three Mile Branch,
no temporary surface water fill for construction access is anticipated. No jurisdictional
wetlands will be affected by the proposed project..
BRIDGE DEMOLITION
NCDOT and all potential contractors will adhere to Best Management Practices for
"Bridge Demolition and Removal" during the removal of bridge 42. Bridge No. 42 is a
three-span structure that consists of pre-cast, pre-stressed concrete channels with an
asphalt wearing surface. The overall length of the structure is 91 feet and the clear
roadway width over the structure is 24 feet. End bents consist of reinforced concrete caps
on timber piles with timber bulkheads and interior bents of reinforced concrete caps on
timber piles. It is anticipated that the bridge will be removed without dropping any
components into the water, however there is the potential that portions of the
superstructure could fall into the river. In this unlikely scenario, the resulting potential
temporary fill would be less than 10 cubic yards.
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 29 January, 2003
the Fish and Wildlife Service (FWS) lists two federally protected species for Cabarrus
County, Carolina heelsplitter (Lasmigona decorata) and Schweinitz's sunflower
(Helianthus schweinitzii).
On June 20, 2003, Tom Dickinson of The Catena Group, Inc. visited the project site to
update protected issues and evaluate potential habitat for the Carolina heelsplitter and
Schweinitz's sunflower. The existing stream is severely degraded, confirming that the
Biological Conclusion of no effect, based on lack of suitable habitat, is valid for the
Carolina heelsplitter. The man dominated community described in the CE was also
evaluated for suitable habitat for Schweinitz's sunflower. Now that the project limits
have been established, it is apparent that there is no suitable habitat within the area of
impact. Therefore, it has been concluded that suitable habitat is not present for
Schweinitz's sunflower and therefore, a Biological Conclusion of no effect has been
rendered for this species.
MITIGATION OPTIONS
As part of the efforts to avoid and minimize jurisdictional impacts, the length of the
culvert is the minimum necessary to accommodate the roadway widening. This will
leave as much surface water as possible "daylighted", though the rip rap fill slopes will
have to extend beyond the culvert, along the banks.
In another minimization effort, a low flow channel will be constructed within one of the
barrels of the culverts, as detailed in sheet 6 of 6 of the permit drawings.
After the avoidance and minimization efforts, the project will still impact 225 linear feet
of existing channel. Three Mile Branch is in the Yadkin-Pee Dee River Basin,
Cataloging Unit 03040105. NCDOT is proposing to provide mitigation through a
combination of in lieu payments to the Wetland Restoration Program (WRP) and the
Afton Run Mitigation site in Cabarrus County. The NCDOT will debit 261.0 linear feet
of stream restoration from the Afton Run site. The remaining balance (utilizing a 2:1
ratio to provide 450.0 linear feet of stream mitigation) of 189.0 feet will be provided
through a payment in the amount of $23,625.00 (189.0 x 2 x $125/ft) to the WRP. A
payment in the amount of $23, 625 will be forwarded to WRP upon receipt of the
requested permits.
SUAE%IARY
It is anticipated that this action will be authorized by a Nationwide Permit 23 (FR number
10, pages 2020-2095; January 15, 2002). We anticipate 401 General Certification number
3361 will apply to this project. 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). 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.
Thank you for your assistance with this project. If you have any questions or need
additional information, please contact Michael G. Wood of The Catena Group at (919)

INTRODUCTION: Bridge No. 47 is included in the 2000-2006 North Carolina Department of
Transportation (NCDOT) Transportation Improvement Program and in the Federal-Aid Bridge
Replacement Program. The location is shown in Figure 1. No substantial environmental impacts
are anticipated. The project is classified as a Federal "Categorical Exclusion".
1. - PURPOSE AND NEED STATEMENT __ _ _ __ _---
Bridge Maintenance Unit records indicate the bridge has a sufficiency rating of 18.8 out of a
possible 100 for a new structure. The bridge is considered to be structurally deficient and
functionally obsolete. The replacement of this inadequate structure will result in safer traffic
operations.
II. EXISTING CONDITIONS
The project is located within the city limits of Concord in Cabarrus County, at the intersection of
SR 1002 and NC 136. (see Figure 1). Development in the area is industrial and residential in
nature.
SR 1002 is classified as a urban minor arterial in the Statewide Functional Classification System
and it is a Federal-Aid Highway. This route is not a designated bicycle route and there is no
indication that an unusual number of bicyclists use "this roadway.
In the vicinity of the bridge, SR 1002 has a 22-foot (6.6-meter) pavement width with 2-foot (0.6-
meter) grass shoulders (see Figures 3 and 4). The roadway grade is in a sag vertical curve
through the project area. The existing bridge is on a tangent. The roadway is situated
approximately 26.0 feet (8.0 meters) above the creek bed.
Bridge No. 47 is a three-span structure that consists of precast, prestressed concrete channels
with an asphalt wearing surface. The end bents consist of reinforced concrete caps on timber
piles with timber bulkheads. The interior bents consist of reinforced concrete caps on timber
piles. The existing bridge (see Figure 3) was constructed in 1964 and is in fair condition. The
overall length of the structure is 91 feet (27.8 meters). The clear roadway width is 24.0 feet (7.2
meters). The posted weight limit on this bridge is 18 tons for single vehicles and 18 tons for
TTST's.
There are no utilities attached to the existing structure, but overhead power lines and a large
water line cross the branch just south of the bridge. There is a large billboard sign located just
north of the bridge, and there is a traffic signal at the east end of the structure. Utility impacts are
anticipated to be high.
The current traffic volume of 9,150 vehicles per day (VPD) is expected to increase to 12,300
VPD by the year 2025. The projected volume includes one percent truck-tractor semi-trailer
(TTST) and three percent dual-tired vehicles (DT). The posted speed limit is 35 miles (55
kilometers) per hour in the project area.
There were two accidents reported in the vicinity of Bridge No. 47 during the period from June
1995 to May 1998. One accident resulted in property damage only. The other accident involved
non-fatal injuries as well as property damage.
Eighteen (18) school buses cross the bridge daily on their morning and afternoon routes.
III. ALTERNATIVES
A. Project Description
The replacement structure will consist of a triple (3) barrel, 10-foot (3.0-meter) wide by 10-foot
(3.0-meter) high reinforced concrete box culvert. This structure will be of sufficient length to
provide three 12-foot (3.6-meter) lanes with 11-foot (3.3-meter) shoulders on each side; four feet
(1.2 meters) of the shoulder width will be paved. The third lane will provide storage for traffic
turning left at the intersection of SR 1002 and NC 136.
The roadway grade of the new structure will be slightly higher than the existing grade at this
location.
The existing roadway will be widened to a 36-foot (10.8-meter) pavement width to provide three
12-foot (3.6-meter) lanes. Eight-foot (2.4-meter) shoulders will be provided on each side; four
feet (1.2 meters) of which will be paved in accordance with the current NCDOT Design Policy.
This roadway will be designed as a major collector. Typical sections of the proposed roadway are
included as Figures 4 and 5.
A separate single barrel, eight foot (2.4 meters) wide by eight foot (2.4 meters) high reinforced
concrete box culvert will be constructed just west of Three Mile Branch to provide for a future
City of Concord greenway trail to be built by the City in this area. The cost of this culvert will be
approximately $105,000. The City has agreed to participate in funding the cost of this culvert by
reimbursing NCDOT for 30% of the cost of this culvert construction.
B. Reasonable and Feasible Alternatives
The two alternatives for replacing Bridge No. 47 that were studied are described below.
Alternative 1 (Preferred) involves replacement of the structure along the existing roadway
alignment. Improvements to the approach roadways will be required for a distance of
2
approximately 275 feet (84 meters) to the west and 350 feet (107 meters) to the east of the
structure. An off-site detour (see Figure 1) will be used to maintain traffic during the construction
period.
Alternative 2 involves replacement of the structure along the existing roadway alignment. A
temporary detour structure located northwest of the existing bridge would serve as an on-site
detour. Improvements to the approach roadways will be required for a distance of approximately
400 feet (122 meters) to the west and 375 feet (115 meters) to the east of the structure. This
alternative is not recommended because of the higher cost of the improvements, impact on the
ecosystem in the vicinity of the site and the effect on adjacent properties.
C. Alternatives Eliminated From Further Consideration
The "do-nothing" alternative-will--eventually necessitate--closure of the bridge: This-is-not
acceptable due to the traffic service provided by SR 1002.
"Rehabilitation" of the old bridge is not feasible due to its age and deteriorated condition.
D. Preferred Alternative
Bridge No. 47 will be replaced at the existing location as shown by Alternative 1 in Figure 2.
Alternative 1 is recommended because it minimizes impacts on the sensitive natural ecosystems
in the vicinity of the site and provides the most economic design. Also, this alternative will have
a minimal impact on the floodplain and on adjacent properties.
A road user analysis was performed based on 9,150 vpd and an average of 0.6 miles (1.0
kilometer) of indirect travel (see Figure 1). At a vehicle operating cost of $0.36 per mile, the cost
of additional travel would be about $300,000 during a five-month construction period. The
estimated cost of maintaining traffic on-site for Alternative 2 is $875,000. This indicates it is
more economical to detour traffic off-site during the construction period.
The NCDOT Division 10 Engineer concurs with the selection of Alternative 1 as the preferred
alternative.

IV. ESTIMATED COSTS
The estimated costs for the two alternatives are as follows (does not include greenway culvert):
Alternative 1
Preferred Alternative 2
Structure $ 245,000 $ 245,000
Roadway Approaches $ 232,000 $ 255,000
Detour Structure and Approaches -0- $ 800,000
Structure Removal $ 17,000 $ 17,000
Misc. & Mob. $ 224,000 $ 244,000
Eng. & Contingencies $ 107,000 $ 114,000
Total Construction Cost $ 825,000 $ 1,675,000
Right-of-way Costs $ 97,100 $ 156,700
Total Project Cost $ 922,100 $ 1,831,700
The estimated cost of the project shown in the 2000-2006 NCDOT Transportation Improvement
Program is $740,000, including $90,000 spent in prior years, $50,000 for right-of-way, and
$600,000 for construction.
V. NATURAL RESOURCES
A biologist visited the project site on September 19, 1998-to verify documented information and
gather field data for a thorough assessment of potential impacts that could be incurred by a
proposed bridge replacement project.
The investigation examined the vegetation surrounding the highway bridge in order to 1) search
for State and federally protected plants and animal species; 2) identify unique or prime-quality
communities; 3) describe the current vegetation and wildlife habitats; 4) identify wetlands; and
5) provide information to assess (and minimize adverse) environmental effects of the proposed
bridge replacement.
A. Methodology
Information sources used to prepare this report include: United States Geological Survey
(USGS) Concord, NC 7.5 minute series topographic map (1969, photo revised 1987); Natural
Resources Conservation Service (MRCS) Soil Survey of Cabarrus County, NC (September,
1988); United States Fish and Wildlife Service (USFWS) National Wetlands Inventory map
(Concord, NC, 1995); USFWS Endangered, Threatened, and Candidate Species and Federal
Species of Concern in North Carolina (September 15, 1999); North Carolina Natural Heritage
Program (NCNHP) computer database, via the Internet, of rare species and unique habitats (July
14, 1999); and NCDOT aerial photography of the study area. Research using these resources was
undertaken prior to the field investigation.
4
A general field survey was conducted along the proposed project corridor on September 19,
1998. Plant communities and their associated wildlife were identified using a variety of
observation techniques including active searching, and identifying characteristic signs of wildlife
such as sounds, tracks, scats, and burrows.
Impact calculations were based on the worst-case scenario using the full right-of way limits for
each individual alternate, the width of the replacement structure, and the length of the project
approaches. The actual construction impacts should be less, but without specific replacement
structure design information the worst case was assumed for the impact calculations.
B. Physiography and Soils
The proposed project lies within the Piedmont Physiographic Province, which includes all parts
_.-ofNorth-Carolina west-of the Fall-Lineend-east of-the-Blue--Ridge-Escarpment.-'T-his-province is
underlain by igneous, crystalline metamorphic, or occasionally, sedimentary rocks. The
topography of the project vicinity can be characterized as gently rolling, with more steeply
sloped areas along drainageways. Elevations in the project vicinity range from approximately
580 to 690 feet (177 to 210 meters) above mean sea level (msl). The elevation in the project area
is approximately 580 to 650 feet (177 to 198 meters) above msl. Current land use in the project
vicinity is mainly a mixture of residential properties, retail stores, and offices.
The project area is located near the border between the Enon-Mecklenburg-Poindexter and
Poindexter-Enon soil series (USDA-NRCS, 1988). The Enon-Mecklenburg-Poindexter
series consists of gently sloping to very steep, well drained soils that have -a clayey or loamy
subsoil, formed in residuum from mixed acidic and basic igneous and metamorphic rock. The
Poindexter-Enon soil series consists of gently sloping to very steep, well drained soils that have a
loamy or clayey subsoil, formed in residuum from diorite, schist, and other basic rock, or from
mixed acidic and basic rock. Field conditions generally conform to the soil survey mapping in
the project area, however near the branch and bridge, soils have been disturbed or altered and do
not match the soil descriptions presented in the county survey report. Individual soil types found
in- the-project-area are described below.
Chewacla sandy loam, frequently flooded, is located in the floodplain east and west of Three
Mile Branch. This soil is somewhat poorly drained. Wehadkee soils are sometimes found in this
soil series in depressions. Wehadkee soils are poorly drained. Both the Chewacla and Wehadkee
soils are listed as hydric (USDA-NRCS, 1991). Upon site investigation, soils in the floodplain of
Three Mile Branch did not exhibit hydric characteristics. The area was highly disturbed and
included fill material.
Poindexter loam, 15 to 45 percent slopes, is located on both sides of the southwest approach
adjacent to the Chewacla soils. This soil is well drained. It occurs on steep uplands that are
adjacent to floodplains, and erosion is a hazard if the soil is unprotected. Enon and Pacolet soils
are included within this soil series. None of the soils included with this series are listed as hydric
(USDA-SCS, 1991).
5
Enon-Urban land complex, 2 to 10 percent slopes, occurs in the remainder of the project area on
both sides of the southwest approach. Enon soils make up 50 to 70 percent of the acreage in this
soil series and Urban land is 15 to 35 percent. Enon soils are well drained, erosion is a hazard
where the ground cover has been removed. Mecklenburg and Poindexter soils are found as
inclusions within this soil series. Urban land consists of areas that have closely spaced houses,
paved streets and parking lots, apartments, and various commercial structures. Runoff from
rooftops and paved surfaces increases the hazard of low-lying areas downstream. Enon-Urban
land complex is not listed as a hydric soil and none of the inclusions found within this soil type
are hydric (USDA-NRCS, 1991).
Enon sandy loam, 8 to 15 percent slopes, is located on both sides of the northeast approach
adjacent to the Chewacla soils. Runoff is very rapid and erosion is a severe hazard. Mecklenburg
and Poindexter soils are included within this soil series. Enon sandy loam is not listed as hydric,
_-nor-are any- of the inclusions-within it(USDA NRCS,--1991). _ _.--
C. Water Resources
1. Stream Characteristics
The proposed project falls within the Yadkin-Pee Dee River Basin, with a subbasin designation
of YAD12 (03-07-12) and a federal hydrologic unit designation of 03040105. Three Mile Branch
discharges into Cold Water Creek approximately 2 miles (3.2 kilometers) southeast of the bridge.
Three Mile Branch has a Class C rating from the North Carolina Department of Environment and
Natural Resources (NCDENR). A Class C designation indicates the creek's suitability for aquatic
life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. The
Classification Date and Index for this portion of the creek is 9/1/74, 13-17-9-4-5.
Point-source discharges located throughout North Carolina are permitted through the National
Pollutant Discharge Elimination System (NPDES) program. A search within the project vicinity,
[0.5 miles(0.8 kilometers)] was conducted for NPDES permitted discharges and no permitted
discharges were found in the area.
Non-point source refers to runoff that enters surface waters through storm water flow or no
defined point of discharge. Storm water runoff from areas with exposed soil as well as from the
abundant paved surfaces in the project area may cause water quality degradation.
Benthic macroinvertebrates are organisms that live in and on the bottom substrates of rivers and
streams. The NCDENR Division of Water Quality (DWQ) uses data on these organisms as a tool
to monitor water quality since benthic macroinvertebrates are sensitive to subtle changes in water
quality. Formerly, the DWQ used the Benthic Macroinvertebrate Ambient Network (BMAN) as
a primary tool for water quality assessment, but phased this method out approximately six years
ago and has converted to a basin wide assessment sampling protocol. Each river basin in the state
is sampled once every five years and the number of sampling stations has been increased within
each basin. Each basin is sampled for biological, chemical and physical data. The DWQ includes
6
the North Carolina Index of Biotic Integrity (NCIBI) as another method to determine general
water quality in the basin wide sampling. The NCIBI is a modification of the Index of Biotic
Integrity initially proposed by Karr (1981) and Karr, et al. (1986). The NCIBI method was
developed for assessing a stream's biological integrity by examining the structure and health of
its fish community. The Index incorporates information about species richness and composition,
trophic composition, fish abundance, and fish condition. The NCIBI summarizes the effects of all
classes of factors influencing aquatic faunal communities (water quality, energy source, habitat
quality, flow regime, and biotic interactions).
The DWQ was contacted regarding sampling information relevant to the project area or vicinity
and they have no data for Three Mile Branch.
2. Anticipated Impacts to Water Resources
a. General Impacts
Neither High Quality Waters (HQW), Water Supplies (WS-I: undeveloped watershed, or WS-II:
predominately undeveloped watersheds) nor Outstanding Resource Waters (ORW) occur within
one mile (1.6 kilometers) of project study area. Impacts to water resources within the study area
will result due to the placement of support structures in the creek. In the short term, construction
of the culvert and approach work will increase sediment loads. Construction related
sedimentation can be harmful to local populations of invertebrates, which are an important part
of the aquatic food chain. Potential adverse effects will be minimized through the
implementation of NCDOT Best Management Practices for Protection of Surface Waters
(BMPs), as applicable, and the use of erosion and sediment control measures as specified in the
State-approved Erosion and Sediment Control Program (ESRP). The NCDOT, in cooperation
with the DWQ, has developed a sedimentation control program for highway projects which
adopts formal BMPs for the protection of surface waters. The following are some methods to
reduce sedimentation and water quality impacts that could be included in an ESRP:
• strict adherence to BMPs for the protection of surface waters during the life of the
project,
• reduction and elimination of direct and non-point discharge into the water bodies and
minimization of activities conducted in streams,
• placement of temporary ground cover or re-seeding of disturbed sites to reduce runoff and
decrease sediment loadings, and
• reduction of clearing and grubbing along the stream.
In the long term, implementation of BMPs for Protection of Surface Waters will result in little or
no lasting impacts on water quality.
b. Impacts Related to Bridge Demolition and Removal
In order to protect the water quality and aquatic life in the project area, the contractor will follow
appropriate guidelines for bridge demolition and removal as presented in the NCDOT Policies:
"Bridge Demolition and Removal in Waters of the United States" and "Best Management
Practices for Bridge Demolition and Removal". The Guidelines for bridge demolition and
7
removal will be implemented, as applicable, in addition to the NCDOT Best Management
Practices for the Protection of Surface Waters.
The streambed substrate in the project area is a mixture of silt and sand. Due to the nature of the
substrate, increased sedimentation would occur if the bridge were dropped into the water during
the demolition and removal process. Sediments could be contained by means of turbidity curtains
or similar devices in areas of concern, if deemed feasible and appropriate. Aquatic life which is
not very mobile could be harmed when components of the bridge enter the water. Species which
filter feed, as well as those species that feed upon them, could be negatively impacted by
increased sedimentation. Although submerged aquatic vegetation is not prevalent in the project
area, continued sedimentation could negatively impact such species if present by obstructing or
reducing the amount of sunlight entering the water. In addition, compaction to the stream bed
would occur from dropping bridge components into the water.
Dropping a portion of the existing structure into water will be allowed only if no other practical
method of removal is feasible. In the event that no other practical method is available, a worst
case scenario is assumed for calculations of fill entering the water. The maximum potential fill
calculated for bridge No. 47 is 10 cubic yards, which is calculated from the superstructure only.
The superstructure consists of precast concrete channels with an asphalt wearing surface. Prior to
dropping any bridge components into the water, the asphalt wearing surface will be removed to
prevent harm to aquatic species. The. substructure consists of precast concrete caps on timber
piles for both the abutments and interior bents. It is anticipated the timber piles can be removed
without dropping them into the water.
D. Biotic Resources
Living systems described in the following sections include communities of associated plants and
animals in the project area. These descriptions refer to the dominant flora and fauna in each
community and the relationship of these biotic components. Classification of natural plant
communities is based on the system used by the NCNBF (Schafale and Weakley 1990).
Scientific nomenclature and common names (when applicable) are used for the plant and animal
species described. Subsequent references to the same species include the common name only.
Vascular plant names follow nomenclature found in Radford et al. (1968) unless more current
information is available. Terrestrial and aquatic wildlife were determined through field
observations, evaluation of habitat, and review of field guides and other documentation.
1. Terrestrial Communities
The predominant terrestrial community found in the project study area is Man-Dominated. There
is also a small disturbed forested area that has been separated into a different community.
Dominant faunal components associated with these areas will be discussed in the community
description below.
8
a. Man-Dominated Community
This highly disturbed community includes the majority of the project area. Vegetation north of
the northeast approach is mostly limited to maintained lawns of businesses. The same conditions
are true east of the approach. The area immediately adjacent to the branch includes fill material
and large rocks for stabilization. Vegetation there consists of irregularly maintained grass, kudzu
(Pueraria lobata), and honeysuckle (Lonicera japonica). There are also many areas of exposed
soil where the vegetation is not abundant.
The south side of the southwest approach consists of maintained lawns, however closer to the
bridge a few species that were probably part of a small floodplain community remain along the
road side. These species include red maple (Ater rubrum), boxelder (Acer negundo), pecan
(Carya illinoensis), Chinese privet (Ligustrum sinense), and Virginia creeper (Parthenocissus
quinque olia - The owner, of the prope1.ty. • this- area -state&that the floodPlain-here-had- been - - -
in
recently logged. The remaining vegetation includes morning glory Qpomoea spp.), grape (Vitis
rotundifolia), greenbriar (Smilax sp.), and honeysuckle. A sewer line is also located in the
floodplain area on both sides of the southwest approach.
West of the southwest approach the floodplain is similar to that of the south side, with the
addition of foxtail (Setaria sp.), goldenrod (Solidago sp.), and aster (Aster sp.). The floodplain
here grades into a small forested area upslope, then vegetation in this quadrant mostly consists of
maintained lawns of residences and businesses.
No wildlife was observed in the Man-Dominated community on the day of the site investigation.
This area has been highly modified and does not provide abundant vegetation for food or cover.
Occasionally some species of birds may pass through this area searching for food sources such as
insects, however wildlife is probably uncommon in this community.
b. Disturbed Forested
This community contains a noticeable amount of woody debris on the ground and many snags.
The dominant species are mixed pines (Pinus spp.) and maples (Acer spp.), and sweet-gum
(Liquidambar styracijlua). Other species intermingled with the dominants include eastern
redeedar (Juniperus virginiana), mockernut hickory (Carya tomentosa), willow oak (Quercus
phellos), southern red oak (Quercus falcata), and dogwood (Corpus jlorida).
No wildlife was observed in this area on the day of the site investigation. This community occurs
on a slope and is surrounded on all sides by developed/disturbed areas. Although the dominant
species of vegetation are not very diverse, some species of wildlife that would find these types of
vegetation beneficial and would not require a large home range may utilize the area. In particular,
species such as tufted titmouse (Parus bicolor), summer tanager (Piranga rubra), and eastern
chipmunk (Tamias striatus) may be found in this community.
9
2. Aquatic Communities
The aquatic community in the project study area exists within Three Mile Branch. The branch is
about 3 to 4 feet (0.9 to 1.2 meters) wide on the west side of the bridge and approximately 10 to
15 feet (3.0 to 5.0 meters) wide east of the bridge. On the day of the site investigation the water
depth was approximately 3 to 5 inches (8 to 13 centimeters) on the west side and 4 to 12 inches
(10 to 30 centimeters) on the east side. The flow was slow and the substrate consisted of silt and
sand. In several places rocks used to stabilize the banks were in the stream bed. The water had a
brown colored foam on the surface in several places and odors from the sewer line were
detectable near the edge of the stream.
A cursory search of the shoreline was conducted for evidence of mussel and clam species. No
shells were noted in or near the stream. In addition, no signs of aquatic life were observed,
however..raccoon_(Procyon_lotor) tracks-were in.the- sand of the stream bed_where the water was _
low.
The District 6 Fisheries Biologist for the NCDENR Wildlife Resources Commission (WRC) was
contacted for information on species that might be found in Three Mile Branch. No data is
available for the stream, however he suspects that various minnows and sunfish may inhabit the
area. He recommended good soil erosion practices for the protection of downstream waters,
mitigation for stream culverting if culverts are used, and the placement of culverts to allow for
fish and wildlife migration.
3. Anticipated Impacts to Biotic Communities
Biotic community impacts resulting from project construction are addressed separately as
terrestrial impacts and aquatic impacts. However, impacts to terrestrial communities, particularly
in locations exhibiting slopes, can result in the aquatic community receiving heavy sediment
loads as a consequence of erosion. It is important to note that construction impacts may not be
restricted to the communities in which the construction activity occurs. The NCDOT's Best
Management Practices for Protection of Surface Waters (B Ws) will be implemented to ensure
that no sediment leaves the construction site.
10
a. Terrestrial Communities
Impacts to terrestrial communities will not be substantial for either alternate. Since Alternate 2
has an on-site detour, impacts will be greater in the short term if this alternate is chosen.

NOTES:
• Impacts are based on the individual right-of-way for each alternate.
• Actual construction impacts may be less than those indicated above; calculations were based
on the worst case scenario.
• . Existing roadways were not considered as part of the total impact where alternates
overlapped existing alignment.
b. Aquatic Communities
The aquatic community in the project study area exists within Three Mile Branch. The
replacement of Bridge No. 47 will result in approximately 0.03 acres of aquatic community
impacts. This represents worst case conditions; actual disturbed area will likely be less.
Additional downstream impacts beyond the project study area are possible. Impacts to the
adjacent communities can have a direct impact on aquatic communities. Construction of the
bridge and approach work as well as the removal of trees will likely result in an increase in
sediment loads and water temperature, and a decrease in dissolved oxygen in the short term.
Construction activities can also increase the possibility of toxins, such as engine fluids and
particulate rubber, entering the waterways and impacting aquatic organisms. These factors can
potentially cause the displacement and mortality of fish and local populations of invertebrates
which inhabit these areas. The NCDOT's Best Management Practices for Protection of Surface
Waters will be implemented, as applicable, to minimize potential adverse impacts due to this
project.
E. Special Topics
1. "Waters of the United States": Jurisdictional Issues
Wetlands and surface waters fall under the broad category of "waters of the United States" as
defined in 33 CFR 328.3 and in accordance with provisions of Section 404 of the Clean Water
11
Act (33 U.S.C. 1344). "Waters of the United States" are regulated by the United States Army
Corps of Engineers (USACE).
Investigation into wetland occurrence in the project study area was conducted using methods of
the 1987 USACE Wetland Delineation Manual. No wetland areas were found within the project
study area. The NWI map-for the project area classifies the stream channel as palustrine, scrub-
shrub, broad-leaved deciduous, temporarily flooded.
Project construction cannot be accomplished without infringing on jurisdictional surface waters.
Anticipated surface water impacts fall under the jurisdiction of the USACE. Up to 60 linear feet
(18 meters) or 0.03 acres (0.01 ha) of jurisdictional surface waters impacts may occur due to the
proposed replacement of Bridge No. 47.
2 -Permits-- _
In accordance with provisions of Section 404 of the. Clean Water Act (CWA) (33 U.S.C. 1344), a
permit is required from the USACE for the discharge of dredged or fill material into "waters of
the United States". Categorical Exclusions (CE) are subject to the provisions of Nationwide
Permit No. 23. This permit authorizes any activities, work and discharges undertaken, assisted,
authorized,. regulated, funded or financed, in whole or in part, by another federal agency. It states
that the activity 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 environment. The CE report is submitted to the USACE to document
that the terms and conditions of the Nationwide Permit No. 23 are met. However, final permit
decisions are left to the discretionary authority of the USACE.
If no practical alternative exists to remove the current bridge other than to drop it into the water,
prior to removal of debris off-site, fill related to demolition procedures will need to be considered
during the permitting process. A worst case scenario will be assumed with the understanding that
if there is any other practical method available, the bridge will not be dropped into the water.
Permitting will be coordinated such that any permit needed for bridge construction will also
address issues related to bridge demolition.
If wetlands or waters will be impacted by filling from a proposed project, a Section 401 Water
Quality Certification may be required from the North Carolina Division of Water Quality. North
Carolina has developed General Certifications (GC) that will satisfy Section 401 of the CWA and
correspond to the USACE's Nationwide Permits. An application must be made if there are any
impacts to "waters of the United States".
3. Mitigation
Since no wetland impacts are anticipated, mitigation will not be required by the USACE.
12
F. Protected Species
Some populations of plants and animals have been or are in the process of decline due either to
natural forces or their inability to coexist with humans. Rare and protected species listed for
Cabarrus County, and any likely impacts to these species as a result of the proposed project
construction, are discussed in the following sections.
1. Federally Protected Species
Plants and animals with federal classification of Endangered (E), Threatened (T), Proposed
Endangered (PE) and Proposed Threatened (PT) are protected under provisions of Section 7 and
Section 9 of the Endangered Species Act of 1973, as amended. The United States Fish and
Wildlife Service lists two federally protected species for Cabarrus County as of the January 3,
2000-listing(Table-2): information-pertinerrtto-these-species and--the- possibility of impacvdue-to
the proposed project is listed below.
TABLE 2
FEDERALLY PROTECTED SPECIES FOR CABARRUS COUNTY
Scientific Name Common Name Status
Helianthus schweinitzii (Schweinitz's sunflower) E
Lasmigona decorata* (Carolina heelsplitter) E
NOTES:
E Denotes Endangered (a species that is in danger of extinction throughout all or a
significant portion of its range).
* Obscure record - the date and/or location of observation is.uncertain.
Species: Helianthus schweinitzii (Schweinitz's sunflower)
Schweinitz's sunflower is a rhizomatous perennial herb approximately 3.3 to 6.6 feet (1.0 to 2.0
meters) tall with a tuberous root. Stems are usually solitary, branching only at or above the mid-
stem, pubescent, and often purple in color. The leaves are opposite on the lower stem, changing
to alternate above. They are lanceolate, pubescent, and have a rough, thick texture. The yellow
flowers have small heads and bloom from September until frost. The outlets are approximately
0.13 to 0.14 inches (33 ) to 3.5 centimeters) long and are glabrous with rounded tips.
Schweinitz's sunflower is endemic to the Piedmont region of the Carolinas. It occurs in open
'habitats such as edges of upland woods, roadside ditches and shoulders, and pastures. Soils are
usually moist to somewhat dry clays, clay loams, or sandy clay loams with a high gravel content.
13
BIOLOGICAL CONCLUSION: NO EFFECT
Potential habitat exists for this species in the open areas of the Man-Dominated community
in the project area. Field work was conducted on September 19, 1998, which is during the
flowering time for this species. All areas of potential habitat were surveyed and thoroughly
searched. Schweinitz's sunflower was not located. This project will not affect Schweinitz's
sunflower.
Species: Lasmigona decorata (Carolina heelsplitter)
The Carolina heelsplitter is a freshwater mussel with an ovate, trapezoid-shaped shell that is
greenish-brown to dark brown. The nacre is pearly-white to bluish-white with a small amount of
orange, which in older specimens may mottle the entire surface. The host fish for this species is
unknown_______.
- - - - - -
Potential habitat for this species may include small to large streams and rivers, as well as
possibly mill ponds. Currently the Carolina heelsplitter is known only from three small streams
and one small river. Substrate consists of mud, muddy sand, or muddy gravel, along with stable
well-shaded stream banks.
BIOLOGICAL CONCLUSION: NO EFFECT
Three Mile Branch appears to be somewhat degraded in the project area. The stream
banks have been stabilized with rocks, many of which have tumbled into the stream bed.
There is an abundance of debris among the rocks on the bank, and the water had a brown
colored foam floating on it on the day of the field investigation. No signs of aquatic life were
observed on the day of the investigation. Published information from the USFWS indicates
that stream bank stability is important for this species, as well as shaded stream banks.
There are no trees along the stream in the project area and the banks are eroded and
degraded. Published information also indicates that this species has been negatively
impacted by point and non-point sources of-pollution. Storm water runoff in the project
area has likely contributed negatively to water quality. The occurrence of this species in
Cabarrus County is reported from obscure records where the date and/or location of the
observation is uncertain. If this species does occur in the county, it is unlikely it would be
found in such a highly man-influenced area. NCNHP records do not list this species as
occurring in the project area or vicinity. This project will not affect the Carolina
heelsplitter.
2. Federal Species of Concern
Federal Species of Concern (FSC) are not legally protected 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. Species designated as FSC are defined as taxa which may
or may not be listed in the future. These species were formerly Candidate 2 (C2) species or
species under consideration for listing for which there is insufficient information to support
14
listing. Some of these species are listed as Endangered, Threatened, or Special Concern by the
NCNHP database of rare plant and animal species and are afforded state protection under the
State Endangered Species Act and the North Carolina Plant Protection and Conservation Act of
1979. Table 3 provides the Federal Species of Concern in Cabarus County and their state
classifications (July 14, 1999, http://www.ncsparks.net/nhp/element.html).

documented populations of this species, one of which is located in Cabarrus County,
several miles west of the project area. This species has not been documented in the
project area or vicinity. Without further information on this species, it is difficult to make
a habitat determination, therefore the presence of potential habitat was assumed.

? Listed by USFWS but not by NCNHP.
3. Summary of Anticipated Impacts
Potential habitat is present in the project area for one federally protected species, Schweinitz's
sunflower. A thorough search was conducted for the species and it was not located. Habitat is
present for three FSCs in the project area as well. The NCNHP database indicates no recorded
occurrences of any federally protected species or FSC within the project area or vicinity.

VI. CULTURAL RESOURCES
A. Compliance Guidelines
This project is subject to compliance with Section 106 of the National Historic Preservation Act
of 1966, as amended, implemented by the Advisory Council on Historic Preservation's
Regulations for Compliance with Section 106, codified at Title 36 CFR Part 800. Section 106
requires Federal agencies to take into account the effect of their undertakings (federally funded,
licensed, or permitted) on properties included in or eligible for inclusion in the National Register
of Historic Places and afford the Advisory Council a reasonable opportunity to comment on such
undertakings. '
B. Historic Architecture
A field survey of the Area of Potential Effects (APE) was conducted on August 6, 1998. All
structures within the APE were photographed, and later reviewed by the State Historic
Preservation Office (SHPO). In a concurrence form dated December 30, 1998 the SHPO
concurred that-there are no historic architectural resources either listed in or eligible for listing in
the National Register of Historic Places within the APE. A copy of the concurrence form is
included in the Appendix.
C. Archaeology
The State Historic Preservation Office (SHPO), in a memorandum dated November 20, 1998
stated that "it is unlikely that any archaeological resources which may be eligible for inclusion in
the National Register of Historic Places will be affected by the project construction. We therefore
recommend that no archaeological investigation be conducted in connection with this project." A
copy of the SHPO memorandum is included in the Appendix.
VII. ENVIRONMENTAL EFFECTS
The project is expected to have an overall positive impact. Replacement of an inadequate bridge
will result in safer traffic operations.
The project is considered to be a Federal "Categorical Exclusion" due to its limited scope and
lack of substantial environmental consequences.
The bridge replacement will not have an adverse effect on the quality of the human or natural
environment with the use of the current North Carolina Department of Transportation standards
and specifications.
The project is not in conflict with any plan, existing land use, or zoning regulation. No change in
land use is expected to result from the construction of the project.
16
No adverse impact on families or communities is anticipated. Right-of-Way acquisition will be
limited. No relocatees are expected with implementation of the proposed alternative.
No adverse effect on public facilities or services is expected. The project is not expected to
adversely affect social, economic, or religious opportunities in the area.
The proposed project will not require right-of-way acquisition or easement from any land
protected under Section 4(f) of the Department of Transportation Act of 1966.
This project has been coordinated with the United States Natural Resources Conservation
Service. The Farmland Protection Policy Act requires all federal agencies or their representatives
to consider the potential impact to prime farmland of all land acquisition and construction
projects. With the exception of the construction of a temporary detour, all work will be done
within the existin -right-of-way. There are no- soils-classified as-prime unique, or-having- state or--
local importance in the vicinity of the project. Therefore, the project will not involve the direct
conversion of farmland acreage within these classifications.
This project is an air quality "neutral" project, so it is not required to be included in the regional
emissions analysis and a project level CO analysis is not required.
Noise levels could increase during construction but will be temporary. If vegetation is disposed
of by burning, all burning shall be done in accordance with applicable local laws and regulations
of the North Carolina State Implementation Plan (SIP) for air quality in compliance with 1
NCAC 2D.0520. This evaluation completes the assessment requirements for highway traffic
noise of Title 23, Code of Federal Regulation (CFR), Part 772 and for air quality (1990 Clean Air
Act Amendments and the National Environmental Policy Act) and no additional reports are
required.
An examination of records at the North Carolina Department of Environment and Natural
Resources, Division of Environmental Management, Groundwater Section and the North
Carolina Department of Human. Resources, Solid Waste Management Section revealed no
underground storage tanks or hazardous waste sites in the project area.
Cabarrus County is a participant in the National Flood Insurance Program. The approximate 100-
year floodplain in the project area is shown in Figure 6. There are no practical alternatives to
crossing the floodplain area. Any shift in alignment will result in an impact area of about the
same magnitude. The proposed project is not anticipated to increase the level or extent of
upstream flood potential.
On the basis of the above discussion, it is concluded that no substantial adverse environmental
impacts will result from implementation of the project.

VIII. AGENCY COMMENTS
A.. Wildlife Resources Commission
In a June 22, 1999 letter to NCDOT the Wildlife Resources Commission, in a general comment,
requested that the existing bridges be replaced with spanning structures, in most cases.
Response: Standard NCDOT practice dictates that a replacement bridge be considered in the
preliminary hydraulic evaluation for all bridge replacement projects. At smaller stream crossing
it is more economical to replace bridges with box culverts. Culverts cost less than bridges,
require less maintenance throughout their service life than bridges, and last longer than bridges.
Therefore, where appropriate NCDOT prefers to use box culverts to replace bridges.
The proposed culvert will-be-designed according-to current NCDOT.-design practices which-- - -- - -
include such measures as buried box bottoms to facilitate fish passage, dry cell(s) to allow
wildlife passage, and placement to minimize channel widening and realignment.
B. City of Concord
In a November 24, 1998 letter to NCDOT, the City of Concord requested a wider bridge on
Cabarms Avenue and suggested a four lane configuration with sidewalks. The City indicated a
willingness to consider participating in the cost for a wider bridge.
Response: The proposed culvert will be designed to accommodate a three-lane roadway section.
However, the culvert can be extended if, in the future, the proposed widening of Cabarrus
Avenue from US 29 to NC 136 is funded in the Transportation Improvement Program. Similarly,
sidewalks would be more appropriate provided under this same future project. The proposed
cross section has sufficient grassed shoulders to allow any pedestrians to use the proposed
facility without walking in the travelway.
In the same November 24, 1999 letter, the City of Concord asked that the detour routes be
studied with adjustments to signal timing and phasing to accommodate detouring traffic during
the construction period.
Response: Before an official detour is posted, NCDOT's local Division office staff will evaluate
area roads and make signal adjustments as necessary to accommodate detouring traffic.
C. City of Concord - Parks and Recreation Department
In a letter dated September 29, 1999 the City of Concord indicated that the Three Mile Branch
corridor had been identified for a future greenway trail. In order to accommodate the trail, they
asked for a tunnel under Cabarrus Avenue.
Response: NCDOT sidewalk policy applies to future greenways and states that City
participation in funding such improvements is required. The City of Concord will participate in
18
funding these improvements. In their January 19, 2000 letter, the City Manager of Concord has
indicated that the City is willing to participate in funding a culvert for the greenway. Therefore, a
separate single barrel reinforced concrete box culvert will be included in this project to
accommodate a greenway trail along Three Mile Branch. The City will be responsible for the
eventual construction of this trail.
A Other Comments
All other comments were addressed during the project development and design for the proposed
project.

MITER QUALITY SECTION
SUBJECT: Nationwide Permit 23 Application for the proposed replacement of
Bridge No. 42 on SR 1002 (Cabarrus Avenue) over Three Mile
Branch, Cabarrus County. Federal Aid Project No. BRSTP-1002(5),
State Project No. 8.2663201, TIP No. B-3422.
The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge
No. 42 over Three Mile Branch (DWQ Index 13-17-9-4-5), a Division of Water Quality
(DWQ) Class "C" Waters of the State. The project involves replacing the current bridge
with a double barrel (2 @ 13-feet wide by 12-feet high) reinforced concrete box culvert
(Please note that the 2 barrel design has replaced the 3 barrel design stated in the CE).
This structure will be of sufficient length to allow the road to be widened to
accommodate three 12-foot travel lanes with 11-foot shoulders on each side. Four feet of
each shoulder will be paved. A separate single barrel, 8-foot wide by 8-foot high
reinforced concrete box culvert will be constructed just west of Three Mile Branch to
provide for a future City of Concord greenway trail. Improvements to the approach
roadways (grading and clearing) will be required for a distance of approximately 275 feet
to the west and 350 feet to the east of the structure. Traffic will be detoured offsite
during construction.
E%IPACTS TO WATERS OF THE UNITED STATES
The topography surrounding the existing bridge and roadway is very steep. Much of the
existing slope is covered with rip rap to prevent erosion. As part of the construction of
the culvert, the fill slopes will extend beyond the culvert wing walls and will also require
rip rap to prevent erosion of the banks. As a result, the loss of channel is being calculated
from one end of the rip rap fill slope, through the culvert, to the other end of the rip rap

fill slope, a total of 225 linear feet. A total of 0.044 acre of surface waters will also be
lost when the culvert is placed in the stream. Due to the small size of Three Mile Branch,
no temporary surface water fill for construction access is anticipated. No jurisdictional
wetlands will be affected by the proposed project..
BRIDGE DEMOLITION
NCDOT and all potential contractors will adhere to Best Management Practices for
"Bridge Demolition and Removal" during the removal of bridge 42. Bridge No. 42 is a
three-span structure that consists of pre-cast, pre-stressed concrete channels with an
asphalt wearing surface. The overall length of the structure is 91 feet and the clear
roadway width over the structure is 24 feet. End bents consist of reinforced concrete caps
on timber piles with timber bulkheads and interior bents of reinforced concrete caps on
timber piles. It is anticipated that the bridge will be removed without dropping any
components into the water, however there is the potential that portions of the
superstructure could fall into the river. In this unlikely scenario, the resulting potential
temporary fill would be less than 10 cubic yards.
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 29 January, 2003
the Fish and Wildlife Service (FWS) lists two federally protected species for Cabarrus
County, Carolina heelsplitter (Lasmigona decorata) and Schweinitz's sunflower
(Helianthus schweinitzii).
On June 20, 2003, Tom Dickinson of The Catena Group, Inc. visited the project site to
update protected issues and evaluate potential habitat for the Carolina heelsplitter and
Schweinitz's sunflower. The existing stream is severely degraded, confirming that the
Biological Conclusion of no effect, based on lack of suitable habitat, is valid for the
Carolina heelsplitter. The man dominated community described in the CE was also
evaluated for suitable habitat for Schweinitz's sunflower. Now that the project limits
have been established, it is apparent that there is no suitable habitat within the area of
impact. Therefore, it has been concluded that suitable habitat is not present for
Schweinitz's sunflower and therefore, a Biological Conclusion of no effect has been
rendered for this species.
MITIGATION OPTIONS
As part of the efforts to avoid and minimize jurisdictional impacts, the length of the
culvert is the minimum necessary to accommodate the roadway widening. This will
leave as much surface water as possible "daylighted", though the rip rap fill slopes will
have to extend beyond the culvert, along the banks.
In another minimization effort, a low flow channel will be constructed within one of the
barrels of the culverts, as detailed in sheet 6 of 6 of the permit drawings.
After the avoidance and minimization efforts, the project will still impact 225 linear feet
of existing channel. Three Mile Branch is in the Yadkin-Pee Dee River Basin,
Cataloging Unit 03040105. NCDOT is proposing to provide mitigation through a
combination of in lieu payments to the Wetland Restoration Program (WRP) and the
Afton Run Mitigation site in Cabarnts County. The NCDOT will debit 261.0 linear feet
of stream restoration from the Afton Run site. The remaining balance (utilizing a 2:1
ratio to provide 450.0 linear feet of stream mitigation) of 189.0 feet will be provided
through a payment in the amount of $23,625.00 (189.0 x 2 x $125/ft) to the WRP. A
payment in the amount of $23, 625 will be forwarded to WRP upon receipt of the
requested permits.
SUMMARY
It is anticipated that this action will be authorized by a Nationwide Permit 23 (FR number
10, pages 2020-2095; January 15, 2002). We anticipate 401 General Certification number
3361 will apply to this project. 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). In accordance with 15A NCAC 211.0501 (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.
Thank you for your assistance with this project. If you have any questions or need
additional information, please contact Michael G. Wood of The Catena Group at (919)
732-1300 or at [e-mail].

INTRODUCTION: Bridge No. 47 is included in the 2000-2006 North Carolina Department of
Transportation (NCDOT) Transportation Improvement Program and in the Federal-Aid Bridge
Replacement Program. The location is shown in Figure 1. No substantial environmental impacts
are anticipated. The project is classified as a Federal "Categorical Exclusion".
1. PURPOSE AND NEED STATEMENT
Bridge Maintenance Unit records indicate the bridge has a sufficiency rating of 18.8 out of a
possible 100 for a new structure. The bridge is considered to be structurally deficient and
functionally obsolete. The replacement of this inadequate structure will result in safer traffic
operations.
II. EXISTING CONDITIONS
The project is located within the city limits of Concord in Cabarrus County, at the intersection of
SR 1002 and NC 136. (see Figure 1). Development in the area is industrial and residential in
nature.
SR 1002 is classified as a urban minor arterial in the Statewide Functional Classification System
and it is a Federal-Aid Highway. This route is not a designated bicycle route and there is no
indication that an unusual number of bicyclists use "this roadway.
In the vicinity of the bridge, SR 1002 has a 22-foot (6.6-meter) pavement width with 2-foot (0.6-
meter) grass shoulders (see Figures 3 and 4). The roadway grade is in a sag vertical curve
through the project area. The existing bridge is on a tangent. The roadway is situated
approximately 26.0 feet (8.0 meters) above the creek bed.
Bridge No. 47 is a three-span structure that consists of precast, prestressed concrete channels
with an asphalt wearing surface. The end bents consist of reinforced concrete caps on timber
piles with timber bulkheads. The interior bents consist of reinforced concrete caps on timber
piles. The existing bridge (see Figure 3) was constructed in 1964 and is in fair condition. The
overall length of the structure is 91 feet (27.8 meters). The clear roadway width is 24.0 feet (7.2
meters). The posted weight limit on this bridge is 18 tons for single vehicles and 18 tons for
TTST's.
There are no utilities attached to the existing structure, but overhead power lines and a large
water line cross the branch just south of the bridge. There is a large billboard sign located just
north of the bridge, and there is a traffic signal at the east end of the structure. Utility impacts are
anticipated to be high.
The current traffic volume of 9,150 vehicles per day (VPD) is expected to increase to 12,300
VPD by the year 2025. The projected volume includes one percent truck-tractor semi-trailer
(TTST) and three percent dual-tired vehicles (DT). The posted speed limit is 35 miles (55
kilometers) per hour in the project area.
There were two accidents reported in the vicinity of Bridge No. 47 during the period from June
1995 to May 1998. One accident resulted in property damage only. The other accident involved
non-fatal injuries as well as property damage.
Eighteen (18) school buses cross the bridge daily on their morning and afternoon routes.
M. ALTERNATIVES
A. Project Description
The replacement structure will consist of a triple (3) barrel, 10-foot (3.0-meter) wide by 10-foot
(3.0-meter) high reinforced concrete box culvert. This structure will be of sufficient length to
provide three 12-foot (3.6-meter) lanes with 11-foot (3.3-meter) shoulders on each side; four feet
(1.2 meters) of the shoulder width will be paved. The third lane will provide storage for traffic
turning left at the intersection of SR 1002 and NC 136.
The roadway grade of the new structure will be slightly higher than the existing grade at this
location. .
The existing roadway will be widened to a 36-foot (10.8-meter) pavement width to provide three
12-foot (3.6-meter) lanes. Eight-foot (2.4-meter) shoulders will be provided on each side; four
feet (1.2 meters) of which will be paved in accordance with the current NCDOT Design Policy.
This roadway will be designed as a major collector. Typical sections of the proposed roadway are
included as Figures 4 and 5.
A separate single barrel, eight foot (2.4 meters) wide by eight foot (2.4 meters) high reinforced
concrete box culvert will be constructed just west of Three Mile Branch to provide for a future
City of Concord greenway trail to be built by the City in this area. The cost of this culvert will be
approximately $105,000. The City has agreed to participate in funding the cost of this culvert by
reimbursing NCDOT for 30% of the cost of this culvert construction.
B. Reasonable and Feasible Alternatives
The two alternatives for replacing Bridge No. 47 that were studied are described below.
Alternative 1 (Preferred) involves replacement of the structure along the existing roadway
alignment. Improvements to the approach roadways will be required for a distance of
2
approximately 275 feet (84 meters) to the west and 350 feet (107 meters) to the east of the
structure. An off-site detour (see Figure 1) will be used to maintain traffic during the construction
period.
Alternative 2 involves replacement of the structure along the existing roadway alignment. A
temporary detour structure located northwest of the existing bridge would serve as an on-site
detour. Improvements to the approach roadways will be required for a distance of approximately
400 feet (122 meters) to the west and 375 feet (115 meters) to the east of the structure. This
alternative is not recommended because of the higher cost of the improvements, impact on the
ecosystem in the vicinity of the site and the effect on adjacent properties.
C. Alternatives Eliminated From Further Consideration
The "do=nothing" ahernative-will-eventuallY necessitate -closure of-the brid This-is not
lam- -
acceptable due to the traffic service provided by SR 1002.
"Rehabilitation" of the old bridge is not feasible due to its age and deteriorated condition.
D. Preferred Alternative
Bridge No. 47 will be replaced at the existing location as shown by Alternative 1 in Figure 2.
Alternative 1 is recommended because it minimizes impacts on the sensitive natural ecosystems
in the vicinity of the site and provides the most economic design. Also, this alternative will have
a minimal impact on the floodplain and on adjacent properties.
A road user analysis was performed based on 9,150 vpd and an average of 0.6 miles (1.0
kilometer) of indirect travel (see Figure 1). At a vehicle operating cost of $0.36 per mile, the cost
of additional travel would be about $300,000 during a five-month construction period The
estimated cost of maintaining traffic on-site for Alternative 2 is $875,000. This indicates it is
more economical to detour traffic off-site during the construction period.
The NCDOT Division 10 Engineer concurs with the selection of Alternative 1 as the preferred
alternative.

IV. ESTIMATED COSTS
The estimated costs for the two alternatives are as follows (does not include greenway culvert):
Alternative 1
Preferred Alternative 2
Structure $ 245,000 $ 245,000
Roadway Approaches $ 232,000 $ 255,000
Detour Structure and Approaches -0- $ 800,000
Structure Removal $ 17,000 $ 17,000
Misc. & Mob. $ 224,000 $ 244,000
Eng. & Contingencies $ 107,000 $ 114,000
Total Construction Cost $ 825,000 $ 1,675,000
Right-of-way Costs $ __ 97,100 $ 11 156;700
Total Project Cost $ 922,100 $ 1,831,700
The estimated cost of the project shown in the 2000-2006 NCDOT Transportation Improvement
Program is $740,000, including $90,000 spent in prior years, $50,000 for right-of-way, and
$600,000 for construction.
V. NATURAL RESOURCES
A biologist visited the project site on September 19, 1998-to verify documented information and
gather field data for a thorough assessment of potential impacts that could be incurred by a
proposed bridge replacement project.
The investigation examined the vegetation surrounding the highway bridge in order to 1) search
for State and federally protected plants and animal species; 2) identify unique or prime-quality
communities; 3) describe the current vegetation and wildlife habitats; 4) identify wetlands; and
5) provide information to assess (and minimize adverse) environmental effects of the proposed
bridge replacement.
A. Methodology
Information sources used to prepare this report include: United States Geological Survey
(USGS) Concord, NC 7.5 minute series topographic map (1969, photo revised 1987); Natural
Resources Conservation Service (NRCS) Soil Survey of Cabamis County, NC (September,
1988); United States Fish and Wildlife Service (USFWS) National Wetlands Inventory map
(Concord, NC, 1995); USFWS Endangered, Threatened, and Candidate Species and Federal
Species of Concern in North Carolina (September 15, 1999); North Carolina Natural Heritage
Program (NCNHP) computer database, via the Internet, of rare species and unique habitats (July
14, 1999); and NCDOT aerial photography of the study area. Research using these resources was
undertaken prior to the field investigation.
4
A general field survey was conducted along the proposed project corridor on September 19,
1998. Plant communities and their associated wildlife were identified using a variety of
observation techniques including active searching, and identifying characteristic signs of wildlife
such as sounds, tracks, scats, and burrows.
Impact calculations were based on the worst-case scenario using the full right-of way limits for
each individual alternate, the width of the replacement structure, and the length of the project
approaches. The actual construction impacts should be less, but without specific replacement
structure design information the worst case was assumed for the impact calculations.
B. Physiography and Soils
The proposed project lies within the Piedmont Physiographic Province, which includes all parts
--of North-Carolina west-of the Fall-Line-and east of-theBlue--Ridge-Escarpment.-'T-his-province is
underlain by igneous, crystalline metamorphic, or occasionally, sedimentary rocks. The
topography of the project vicinity can be characterized as gently rolling, with more steeply
sloped areas along dr in oeways. Elevations in the project vicinity range from approximately
580 to 690 feet (177 to 210 meters) above mean sea level (msl). The elevation in the project area
is approximately 580 to 650 feet (177 to 198 meters) above msl. Current land use in the project
vicinity is mainly a mixture of residential properties, retail stores, and offices.
The project area is located near the border between the Enon-Mecklenburg-Poindexter and
Poindexter-Enon soil series (USDA-NRCS, 1988). The Enon-Mecklenburg-Poindexter
series consists of gently sloping to very steep, well drained soils that have -a clayey or loamy
subsoil, formed in residuum from mixed acidic and basic igneous and metamorphic rock. The
Poindexter-Enon soil series consists of gently sloping to very steep, well drained soils that have a
loamy or clayey subsoil, formed in residuum from diorite, schist, and other basic rock, or from
mixed acidic and basic rock. Field conditions generally conform to the soil survey mapping in
the project area, however near the branch and bridge, soils have been disturbed or altered and do
not match the soil descriptions presented in the county survey report. Individual soil types found
in-the•project-area are described below.
Chewacla sandy loam, frequently flooded, is located in the floodplain east and west of Three
Mile Branch. This soil is somewhat poorly drained. Wehadkee soils are sometimes found in this
soil series in depressions. Wehadkee soils are poorly drained. Both the Chewacla and Wehadkee
soils are listed as hydric (USDA-NRCS, 1991). Upon site investigation, soils in the floodplain of
Three Mile Branch did not exhibit hydric characteristics. The area was highly disturbed and
included fill material.
Poindexter loam, 15 to 45 percent slopes, is located on both sides of the southwest approach
adjacent to the Chewacla soils. This soil is well drained. It occurs on steep uplands that are
adjacent to floodplains, and erosion is a hazard if the soil is unprotected. Enon and Pacolet soils
are included within this soil series. None of the soils included with this series are listed as hydric
(USDA-SCS, 1991).
5
Enon-Urban land complex, 2 to 10 percent slopes, occurs in the remainder of the project area on
both sides of the southwest approach. Enon soils make up 50 to 70 percent of the acreage in this
soil series and Urban land is 15 to 35 percent. Enon soils are well drained, erosion is a hazard
where the ground cover has been removed. Mecklenburg and Poindexter soils are found as
inclusions within this soil series. Urban land consists of areas that have closely spaced houses,
paved streets and parking lots, apartments, and various commercial structures. Runoff from
rooftops and paved surfaces increases the hazard of low-lying areas downstream. Enon-Urban
land complex is not listed as a hydric soil and none of the inclusions found within this soil type
are hydric (USDA-NRCS, 1991).
Enon sandy loam, 8 to 15 percent slopes, is located on both sides of the northeast approach
adjacent to the Chewacla soils. Runoff is very rapid and erosion is a severe hazard. Mecklenburg
and Poindexter soils are included within this soil series. Enon sandy loam is not listed as hydric,

C. Water Resources
1. Stream Characteristics
The proposed project falls within the Yadkin-Pee Dee River Basin, with a subbasin designation
of YAD12 (03-07-12) and a federal hydrologic unit designation of 03040105. Three Mile Branch
discharges into Cold Water Creek approximately 2 miles (3.2 kilometers) southeast of the bridge.
Three Mile Branch has a Class C rating from the North Carolina Department of Environment and
Natural Resources (NCDENR). A Class C designation indicates the creek's suitability for aquatic
life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. The
Classification Date and Index for this portion of the creek is 9/1/74, 13-17-9-4-5.
Point-source discharges located throughout North Carolina are permitted through the National
Pollutant Discharge Elimination System (NPDES) program. A search within the project vicinity,
[0.5 miies(0.8 kilometers)] was conducted for NPDES permitted discharges and no permitted
discharges were found in the area.
Non-point source refers to runoff that enters surface waters through storm water flow or no
defined point of discharge. Storm water runoff from areas with exposed soil as well as from the
abundant paved surfaces in the project area may cause water quality degradation.
Benthic macroinvertebrates are organisms that live in and on the bottom substrates of rivers and
streams. The NCDENR Division of Water Quality (DWQ) uses data on these organisms as a tool
to monitor water quality since benthic macroinvertebrates are sensitive to subtle changes in water
quality. Formerly, the DWQ used the Benthic Macroinvertebrate Ambient Network (BMAN) as
a primary tool for water quality assessment, but phased this method out approximately six years
ago and has converted to a basin wide assessment sampling protocol. Each river basin in the state
is sampled once every five years and the number of sampling stations has been increased within
each basin. Each basin is sampled for biological, chemical and physical data. The DWQ includes
6
the North Carolina Index of Biotic Integrity (NCIBI) as another method to determine general
water quality in the basin wide sampling. The NCIBI is a modification of the Index of Biotic
Integrity initially proposed by Karr (1981) and Karr, et al. (1986). The NCIBI method was
developed for assessing a stream's biological integrity by examining the structure and health of
its fish community. The Index incorporates information about species richness and composition,
trophic composition, fish abundance, and fish condition. The NCIBI summarizes the effects of all
classes of factors influencing aquatic faunal communities (water quality, energy source, habitat
quality, flow regime, and biotic interactions).
The DWQ was contacted regarding sampling information relevant to the project area or vicinity
and they have no data for Three Mile Branch.
2. Anticipated Impacts to Water Resources
a. General Impacts
Neither High Quality Waters (HQW), Water Supplies (WS-I: undeveloped watershed, or WS-II:
predominately undeveloped watersheds) nor Outstanding Resource Waters (ORW) occur within
one mile (1.6 kilometers) of project study area. Impacts to water resources within the study area
will result due to the placement of support structures in the creek. In the short term, construction
of the culvert and approach work will increase sediment loads. Construction related
sedimentation can be harmful to local populations of invertebrates, which are an important part
of the aquatic food chain. Potential adverse effects will be minimized through the
implementation of NCDOT Best Management Practices for Protection of Surface Waters
(BMPs), as applicable, and the use of erosion and sediment control measures as specified in the
State-approved Erosion and Sediment Control Program (ESRP). The NCDOT, in cooperation
with the DWQ, has developed a sedimentation control program for highway projects which
adopts formal BMPs for the protection of surface waters. The following are some methods to
reduce sedimentation and water quality impacts that could be included in an ESRP:
• strict adherence to BMPs for the protection of surface waters during the life of the
project,
• reduction and elimination of direct and non-point discharge into the water bodies and
minimization of activities conducted in streams,
• placement of temporary ground cover or re-seeding of disturbed sites to reduce runoff and
decrease sediment loadings, and
• reduction of clearing and grubbing along the stream.
In the long term, implementation of BMPs for Protection of Surface Waters will result in little or
no lasting impacts on water quality.
b. Impacts Related to Bridge Demolition and Removal
In order to protect the water quality and aquatic life in the project area, the contractor will follow
appropriate guidelines for bridge demolition and removal as presented in the NCDOT Policies:
"Bridge Demolition and Removal in Waters of the United States." and "Best Management
Practices for Bridge Demolition and Removal". The Guidelines for bridge demolition and
7
removal will be implemented, as applicable, in addition to the NCDOT Best Management
Practices for the Protection of Surface Waters.
The streambed substrate in the project area is a mixture of silt and sand. Due to the nature of the
substrate, increased sedimentation would occur if the bridge were dropped into the water during
the demolition and removal process. Sediments could be contained by means of turbidity curtains
or similar devices in areas of concern, if deemed feasible and appropriate. Aquatic life which is
not very mobile could be harmed when components of the bridge enter the water. Species which
filter feed, as well as those species that feed upon them, could be negatively impacted by
increased sedimentation. Although submerged aquatic vegetation is not prevalent in the project
area, continued sedimentation could negatively impact such species if present by obstructing or
reducing the amount of sunlight entering the water. In addition, compaction to the stream bed
would occur from dropping bridge components into the water.
Dropping a portion of the existing structure into water will be allowed only if no other practical
method of removal is feasible. In the event that no other practical method is available, a worst
case scenario is assumed for calculations of fill entering the water. The maximum potential fill
calculated for bridge No. 47 is 10 cubic yards, which is calculated from the superstructure only.
The superstructure consists of precast concrete channels with an asphalt wearing surface. Prior to
dropping any bridge components into the water, the asphalt wearing surface will be removed to
prevent harm to aquatic species. The. substructure consists of precast concrete caps on timber
piles for both the abutments and interior bents. It is anticipated the timber piles can be removed
without dropping them into the water.
D. Biotic Resources
Living systems described in the following sections include communities of associated plants and
animals in the project area. These descriptions refer to the dominant flora and fauna in each
community and the relationship of these biotic components. Classification of natural plant
communities is based on the system used by the NCNF? (Schafale and Weakley 1990).
Scientific nomenclature and common names (when applicable) are used for the plant and animal
species described. Subsequent references to the same species include the common name only.
Vascular plant names follow nomenclature found in Radford et al. (1968) unless more current
information is available. Terrestrial and aquatic wildlife were determined through field
observations, evaluation of habitat, and review of field guides and other documentation.
1. Terrestrial Communities
The predominant terrestrial community found in the project study area is Man-Dominated. There
is also a small disturbed forested area that has been separated into a different community.
Dominant faunal components associated with these areas will be discussed in the community
description below.
a. Man-Dominated Community
This highly disturbed community includes the majority of the project area. Vegetation north of
the northeast approach is mostly limited to maintained lawns of businesses. The same conditions
are true east of the approach. The area immediately adjacent to the branch includes fill material
and large rocks for stabilization. Vegetation there consists of irregularly maintained grass, kudzu
(Pueraria lobata), and honeysuckle (Lonicera japonica). There are also many areas of exposed
soil where the vegetation is not abundant.
The south side of the southwest approach consists of maintained lawns, however closer to the
bridge a few species that were probably part of a small floodplain community remain along the
road side. These species include red maple (Ater rubrum), boxelder (Aeer negundo), pecan
(Carya illinoensis), Chinese privet (Ligustrum sinense), and Virginia creeper (Parthenocissus
quinquefolia)? The owner of the property-in-this=area-stated-that the floodplain-here-had been-
recently logged. The remaining vegetation includes morning glory Qpomoea spp.), grape (Vitis
rotundifolia), greenbriar (Smilax sp.), and honeysuckle. A sewer line is also located in the
floodplain area on both sides of the southwest approach.
West of the southwest approach the floodplain is similar to that of the south side, with the
addition of foxtail (Setaria sp.), goldenrod (Solidago sp.), and aster (Aster sp.). The floodplain
here grades into a small forested area upslope, then vegetation in this quadrant mostly consists of
maintained lawns of residences and businesses.
No wildlife was observed in the Man-Dominated community on the day of the site investigation.
This area has been highly modified and does not provide abundant vegetation for food or cover.
Occasionally some species of birds may pass through this area searching for food sources such as
insects, however wildlife is probably uncommon in this community.
b. Disturbed Forested
This community contains a noticeable amount of woody debris on the ground and many snags.
The dominant species are mixed pines (Pinus spp.) and maples (Ater spp.), and sweet-gum
(Liquidambar styracijlua). Other species intermingled with the dominants include eastern
redcedar (Juniperus virginiana), mockernut hickory (Carya tomentosa), willow oak (Quercus
phellos), southern red oak (Quercus falcata), and dogwood (Corpus jlorida).
No wildlife was observed in this area on the day of the site investigation. This community occurs
on a slope and is surrounded on all sides by developed/disturbed areas. Although the dominant
species of vegetation are not very diverse, some species of wildlife that would find these types of
vegetation beneficial and would not require a large home range may utilize the area. In particular,
species such as tufted titmouse (Parus bicolor), summer tanager (Piranga rubra), and eastern
chipmunk (Tamias striatus) may be found in this community.

2. Aquatic Communities
The aquatic community in the project study area exists within Three Mile Branch. The branch is
about 3 to 4 feet (0.9 to 1.2 meters) wide on the west side of the bridge and approximately 10 to
15 feet (3.0 to 5.0 meters) wide east of the bridge. On the day of the site investigation the water
depth was approximately 3 to 5 inches (8 to 13 centimeters) on the west side and 4 to 12 inches
(10 to 30 centimeters) on the east side. The flow was slow and the substrate consisted of silt and
sand. In several places rocks used to stabilize the banks were in the stream bed. The water had a
brown colored foam on the surface in several places and odors from the sewer line were
detectable near the edge of the stream.
A cursory search of the shoreline was conducted for evidence of mussel and clam species. No
shells were noted in or near the stream. In addition, no signs of aquatic life were observed,
..however_raccoon(Procyon_lotor) tracks were in.the- sand of the-stream bed-where the water was
low.
The District 6 Fisheries Biologist for the NCDENR Wildlife Resources Commission (WRC) was
contacted for information on species that might be found in Three Mile Branch. No data is
available for the stream, however he suspects that various minnows and sunfish may inhabit the
area. He recommended good soil erosion practices for the protection of downstream waters,
mitigation for stream culverting if culverts are used, and the placement of culverts to allow for
fish and wildlife migration.
3. Anticipated Impacts to Biotic Communities
Biotic community impacts resulting from project construction are addressed separately as
terrestrial impacts and aquatic impacts. However, impacts to terrestrial communities, particularly
in locations exhibiting slopes, can result in the aquatic community receiving heavy sediment
loads as a consequence of erosion. It is important to note that construction impacts may not be
restricted to the communities in which the construction activity occurs. The NCDOT's Best
Management Practices for Protection of Surface Waters (B MPs) will be implemented to ensure
that no sediment leaves the construction site.
10
a. Terrestrial Communities
Impacts to terrestrial communities will not be substantial for either alternate. Since Alternate 2
has an on-site detour, impacts will be greater in the short term if this alternate is chosen.

NOTES:
• Impacts are based on the individual right-of-way for each alternate.
• Actual construction impacts may be less than those indicated above; calculations were based
on the worst case scenario.
• Existing roadways were not considered as part of the total impact where alternates
overlapped existing alignment.
b. Aquatic Communities
The aquatic community in the project study area exists within Three Mile Branch. The
replacement of Bridge No. 47 will result in approximately 0.03 acres of aquatic community
impacts. This represents worst case conditions; actual disturbed area will likely be less.
Additional downstream impacts beyond the project study area are possible. Impacts to the
adjacent communities can have a direct impact on aquatic communities. Construction of the
bridge and approach work as well as the removal of trees will likely result in an increase in
sediment loads and water temperature, and a decrease in dissolved oxygen in the short term.
Construction activities can also increase the possibility of toxins, such as engine fluids and
particulate rubber, entering the waterways and impacting aquatic organisms. These factors can
potentially cause the displacement and mortality of fish and local populations of invertebrates
which inhabit these areas. The NCDOT's Best Management Practices for Protection of Surface
Waters will be implemented, as applicable, to minimize potential adverse impacts due to this
project.
E. Special Topics
1. "Waters of the United States": Jurisdictional Issues
Wetlands and surface waters fall under the broad category of "waters of the United States" as
defined in 33 CFR 328.3 and in accordance with provisions of Section 404 of the Clean Water
11
Act (33 U.S.C. 1344). "Waters of the United States" are regulated by the United States Army
Corps of Engineers (USACE).
Investigation into wetland occurrence in the project study area was conducted using methods of
the 1987 USACE Wetland Delineation Manual. No wetland areas were found within the project
study area. The NWI map for the project area classifies the stream channel as palustrine, scrub-
shrub, broad-leaved deciduous, temporarily flooded.
Project construction cannot be accomplished without infringing on jurisdictional surface waters.
Anticipated surface water impacts fall under the jurisdiction of the USACE. Up to 60 linear feet
(18 meters) or 0.03 acres (0.01 ha) of jurisdictional surface waters impacts may occur due to the
proposed replacement of Bridge No. 47.
2. -Permits
In accordance with provisions of Section 404 of the. Clean Water Act (CWA) (33 U.S.C. 1344), a
permit is required from the USACE for the discharge of dredged or fill material into "waters of
the United States". Categorical Exclusions (CE) are subject to the provisions of Nationwide
Permit No. 23. This permit authorizes any activities, work and discharges undertaken, assisted,
authorized,. regulated, funded or financed, in whole or in part, by another federal agency. It states
that the activity 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 environment. The CE report is submitted to the USACE to document
that the terms and conditions of the Nationwide Permit No. 23 are met. However, final permit
decisions are left to the discretionary authority of the USACE.
If no practical alternative exists to remove the current bridge other than to drop it into the water,
prior to removal of debris off-site, fill related to demolition procedures will need to be considered
during the permitting process. A worst case scenario will be assumed with the understanding that
if there is any other practical method available, the bridge will not be dropped into the water.
Permitting will be coordinated such that any permit needed for bridge construction will also
address issues related to bridge demolition.
If wetlands or waters will be impacted by filling from a proposed project, a Section 401 Water
Quality Certification may be required from the North Carolina Division of Water Quality. North
Carolina has developed General Certifications (GC) that will satisfy Section 401 of the CWA and
correspond to the USACE's Nationwide Permits. An application must be made if there are any
impacts to "waters of the United States".
3. Mitigation
Since no wetland impacts are anticipated, mitigation will not be required by the USACE.
12
F. Protected Species
Some populations of plants and animals have been or are in the process of decline due either to
natural forces or their inability to coexist with humans. Rare and protected species listed for
Cabarrus County, and any likely impacts to these species as a result of the proposed project
construction, are discussed in the following sections.
Federally Protected Species
Plants and animals with federal classification of Endangered (E), Threatened (T), Proposed
Endangered (PE) and Proposed Threatened (PT) are protected under provisions of Section 7 and
Section 9 of the Endangered Species Act of 1973, as amended. The United States Fish and
Wildlife Service lists two federally protected species for Cabarrus County as of the January 3,
2000-listing fTable-2): Information-pertinentto-these?species and-the-possibility of impactzluerto
the proposed project is listed below.
TABLE 2
FEDERALLY PROTECTED SPECIES FOR CABARRUS COUNTY
Scientific Name Common Name Status
Helianthus schweinitzii (Schweinitz's sunflower) E
Lasmigona decorata* (Carolina heelsplitter) E
NOTES:
E Denotes Endangered (a species that is in danger of extinction throughout all or a
significant portion of its range).
* Obscure record - the date and/or location of observation is uncertain.
Species: Helianthus schweinitzii (Schweinitz's sunflower)
Schweinitz's sunflower is a rhizomatous perennial herb approximately 3.3 to 6.6 feet (1.0 to 2.0
meters) tall with a tuberous root. Stems are usually solitary, branching only at or above the mid-
stem, pubescent, and often purple in color. The leaves are opposite on the lower stem, changing
to alternate above. They are lanceolate, pubescent, and have a rough, thick texture. The yellow
flowers have small heads and bloom from September until frost. The nutlets are approximately
0.13 to 0.14 inches (3.3 to 3.5 centimeters) long and are glabrous with rounded tips.
Schweinitz's sunflower is endemic to the Piedmont region of the Carolinas. It occurs in open
habitats such as edges of upland woods, roadside ditches and shoulders, and pastures. Soils are
usually moist to somewhat dry clays, clay loams, or sandy clay loams with a high gravel content.
13
BIOLOGICAL CONCLUSION: NO EFFECT
Potential habitat exists for this species in the open areas of the Man-Dominated community
in the project area. Field work was conducted on September 19, 1998, which is during the
flowering time for this species. All areas of potential habitat were surveyed and thoroughly
searched. Schweinitz's sunflower was not located. This project will not affect Schweinitz's
sunflower.
Species: Lasmigona decorata (Carolina heelsplitter)
The Carolina heelsplitter is a freshwater mussel with an ovate, trapezoid-shaped shell that is
greenish-brown to dark brown. The nacre is pearly-white to bluish-white with a small amount of
orange, which in older specimens may mottle the entire surface. The host fish for this species is
unknown-
Potential habitat for this species may include small to large streams and rivers, as well as
possibly mill ponds. Currently the Carolina heelsplitter is known only from three small streams
and one small river. Substrate consists of mud, muddy sand, or muddy gravel, along with stable
well-shaded stream banks.
BIOLOGICAL CONCLUSION: NO EFFECT
Three Mile Branch appears to be somewhat degraded in the project area. The stream
banks have been stabilized with rocks, many of which have tumbled into the stream bed.
There is an abundance of debris among the rocks on the bank, and the water had a brown
colored foam floating on it on the day of the field investigation. No signs of aquatic life were
observed on the day of the investigation. Published information from the USFWS indicates
that stream bank stability is important for this species, as well as shaded stream banks.
There are no trees along the stream in the project area and the banks are eroded and
degraded. Published information also indicates that this species has been negatively
impacted by point and non-point sources of pollution. Storm water runoff in the project
area has likely contributed negatively to water quality. The occurrence of this species in
Cabarrus County is reported from obscure records where the date and/or location of the
observation is uncertain. If this species does occur in the county, it is unlikely it would be
found in such a highly man-influenced area. NCNHP records do not list this species as
occurring in the project area or vicinity. This project will not affect the Carolina
heelsplitter.
2. Federal Species of Concern
Federal Species of Concern (FSC) are not legally protected 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. Species designated as FSC are defined as taxa which may
or may not be listed in the future. These species were formerly Candidate 2 (C2) species or
species under consideration for listing for which there is insufficient information to support
14
listing. Some of these species are listed as Endangered, Threatened, or Special Concern by the
NCNHP database of rare plant and animal species and are afforded state protection under the
State Endangered Species Act and the North Carolina Plant Protection and Conservation Act of
1979. Table 3 provides the Federal Species of Concern in Cabarrus County and their state
classifications (July 14, 1999, http://www.ncsparl s.net/nhp/element.htnl).

3. Summary of Anticipated Impacts
Potential habitat is present in the project area for one federally protected species, Schweinitz's
sunflower. A thorough search was conducted for the species and it was not located. Habitat is
present for three FSCs in the project area as well. The NCNHP database indicates no recorded
occurrences of any federally protected species or FSC within the project area or vicinity.
15
VI. CULTURAL RESOURCES
A. Compliance Guidelines
This project is subject to compliance with Section 106 of the National Historic Preservation Act
of 1966, as amended, implemented by the Advisory Council on Historic Preservation's
Regulations for Compliance with Section 106, codified at Title 36 CFR Part 800. Section 106
requires Federal agencies to take into account the effect of their undertakings (federally funded,
licensed, or permitted) on properties included in or eligible for inclusion in the National Register
of Historic Places and afford the Advisory Council a reasonable opportunity to comment on such
undertakings.
B. Historic Architecture
A field survey of the Area of Potential Effects (APE) was conducted on August 6, 1998. All
structures within the APE were photographed, and later reviewed by the State Historic
Preservation Office (SHPO). In a concurrence form dated December 30, 1998 the SHPO
concurred that-there are no historic architectural resources either listed in or eligible for listing in
the National Register of Historic Places within the APE. A copy of the concurrence form is
included in the Appendix.
C. Archaeology
The State Historic Preservation Office (SHPO), in a memorandum dated November 20, 1998
stated that "it is unlikely that any archaeological resources which may be eligible for inclusion in
the National Register of Historic Places will be affected by the project construction. We therefore
recommend that no archaeological investigation be conducted in connection with this project." A
copy of the SHPO memorandum is included in the Appendix.
VII. ENVIRONMENTAL EFFECTS
The project is expected to have an overall positive impact. Replacement of an inadequate bridge
will result in safer traffic operations.
The project is considered to be a Federal "Categorical Exclusion" due to its limited scope and
lack of substantial environmental consequences.
The bridge replacement will not have an adverse effect on the quality of the human or natural
environment with the use of the current North Carolina Department of Transportation standards
and specifications.
The project is not in conflict with any plan, existing land use, or zoning regulation. No change in
land use is expected to result from the construction of the project.
16 .
No adverse impact on families or communities is anticipated. Right-of-Way acquisition will be
limited. No relocatees are expected with implementation of the proposed alternative.
No adverse effect on public facilities or services is expected. The project is not expected to
adversely affect social, economic, or religious opportunities in the area.
The proposed project will not require right-of-way acquisition or easement from any land
protected under Section 4(f) of the Department of Transportation Act of 1966.
This project has been coordinated with the United States Natural Resources Conservation
Service. The Farmland Protection Policy Act requires all federal agencies or their representatives
to consider the potential impact to prime farmland of all land acquisition and construction
projects. With the exception of the construction of a temporary detour, all work will be done
-within-the existin -right-of=way. There are no- soils -classified-=as°prime; unique, or having, state or--
local importance in the vicinity of the project. Therefore, the project will not involve the direct
conversion of farmland acreage within these classifications.
This project is an air quality "neutral" project, so it is not required to be included in the regional
emissions analysis and a project level CO analysis is not required.
Noise levels could increase during construction but will be temporary. If vegetation is disposed
of by burning, all burning shall be done in accordance with applicable local laws and regulations
of the North Carolina State Implementation Plan (SIP) for air quality in compliance with 15
NCAC 2D.0520. This evaluation completes the assessment requirements for highway traffic
noise of Title 23, Code of Federal Regulation (CFR), Part 772 and for air quality (1990 Clean Air
Act Amendments and the National Environmental Policy Act) and no additional reports are
required.
An examination of records at the North Carolina Department of Environment and Natural
Resources, Division of Environmental Management, Groundwater Section and the North
Carolina Department of Human. Resources, Solid Waste Management Section revealed no
underground storage tanks or hazardous waste sites in the project area.
Cabamis County is a participant in the National Flood Insurance Program. The approximate 100-
year floodplain in the project area is shown in Figure 6. There are no practical alternatives to
crossing the floodplain area. Any shift in alignment will result in an impact area of about the
same magnitude. The proposed project is not anticipated to increase the level or extent of
upstream flood potential.
On the basis of the above discussion, it is concluded that no substantial adverse environmental
impacts will result from implementation of the project.

VIII. AGENCY COMMENTS
A., Wildlife Resources Commission
In a,June 22, 1999 letter to NCDOT the Wildlife Resources Commission, in a general comment,
requested that the existing bridges be replaced With spanning structures, in most cases.
Response: Standard NCDOT practice dictates that a replacement bridge be considered in the
preliminary hydraulic evaluation for all bridge replacement projects. At smaller stream crossing
it is more economical to replace bridges with box culverts. Culverts cost less than bridges,
require less maintenance throughout their service life than bridges, and last longer than bridges.
Therefore, where appropriate NCDOT prefers to use box culverts to replace bridges.
The proposed culvert will-be-designed according-to current NCDOT: design practices which-
include such measures as buried box bottoms to facilitate fish passage, dry cell(s) to allow
wildlife passage, and placement to minimize channel widening and realignment.
B. City of Concord
In a November 24, 1998 letter to NCDOT, the City of Concord requested a wider bridge on
Cabarrus Avenue and suggested a four lane configuration with sidewalks. The City indicated a
willingness to consider participating in the cost for a wider bridge.
Response: The proposed culvert will be designed to accommodate a three-lane roadway section.
However, the culvert can be extended if, in the future, the proposed widening of Cabamis
Avenue from US 29 to NC 136 is funded in the Transportation Improvement Program. Similarly,
sidewalks would be more appropriate provided under this same future project. The proposed
cross section has sufficient grassed shoulders to allow any pedestrians to use the proposed
facility without walking in the travelway.
In the same November 24, 1999 letter, the City of Concord asked that the detour routes be
studied with adjustments to signal timing and phasing to accommodate detouring traffic during
the construction period.
Response: Before an official detour is posted, NCDOT's local Division office staff will evaluate
area roads and make signal adjustments as necessary to accommodate detouring traffic.
C. City of Concord - Parks and Recreation. Department
In a letter dated September 29, 1999 the City of Concord indicated that the Three Mile Branch
corridor had been identified for a future greenway trail. In order to accommodate the trail, they
asked for a tunnel under Cabarrus Avenue.
Response: NCDOT sidewalk policy applies to future greenways and states that City
participation in funding such improvements is required. The City of Concord will participate in
18
funding these improvements. In their January 19, 2000 letter, the City Manager of Concord has
indicated that the City is willing to participate in funding a culvert for the greenway. Therefore, a
separate single barrel reinforced concrete box culvert will be included in this project to
accommodate a greenway trail along Three Mile Branch. The City will be responsible for the
eventual construction of this trail.
A Other Comments
All other comments were addressed during the project development and design for the proposed
project.
