SUBJECT: Application for Nationwide Permits 13, 23, 33 and Section 401 Water
Quality Certifications for the proposed replacement of Bridge No. 238
over Garden Creek on SR 1506 (Garden Creek Church Road) in
McDowell County, Division 13, Federal Aid Project No. BRZ-1506(2),
State Project No. 8.2872401, WBS Element 33543.1.1, TIP No. B-4196.
Dear Sir:
Please see the enclosed PCN, permit drawings, utility drawings, and design plans. A Categorical
Exclusion was completed for this project in June 2006 and distributed shortly thereafter.
Additional copies are available upon request. NCDOT proposes to replace the existing 37-foot
long Bridge No. 238 with athree-barrel 11-foot wide by 8-foot high reinforced concrete box
culvert. This would create an improved horizontal alignment at the intersection of SR 1506 and
US 70/LTS 221 B. Improvements to the roadway will be required for a distance of approximately
200 feet to the east and 40 feet to the west of the new structure. There will be 151 linear feet of
permanent stream impacts and 0.03 acre of temporary stream impacts incurred from the
construction of this project. In addition, there will be 5 feet of temporary stream impacts as a
result of utility relocation. Traffic will be detoured off-site during construction.
IMPACTS TO WATERS OF THE UNITED STATES
General Description:
The single water resource located in the project area is Garden Creek (referred to in the CE as an
unnamed tributary to the Catawba River). Garden Creek has not been assigned a DWQ Stream
Index Number. The nearest designated water resource is the Catawba River, which is located
approximately 1,100 feet downstream of the project area. The Catawba River downstream of the
project area is designated by DWQ as Stream Index Number 11-(1) and has been assigned a
primary water resource classification of "C" and a supplemental water resource classification of
"Tr". It is located in the Catawba River Basin (Division of Water Quality (DWQ)) subbasin

03-08-30. There are no High Quality Waters (HQW), Water Supplies (WS-I or WSII), or
Outstanding Resource Waters (ORW) within 1.0 mile of the project study area. Garden Creek
does not appear on the North Carolina DWQ 303(d) List (updated 2006). There are no 303(d)
streams within 1.0 mile downstream of project area. There are no jurisdictional wetlands within
the project area.
Permanent Impacts:
There will be 151 linear feet of permanent stream impacts that include 81 feet from the
installation of the reinforced concrete box culvert and 70 feet for bank stabilization, as depicted
on permit drawing 5 of 5 "Enlargement".
Temporary Impacts:
There will be 0.03 acre (86 linear feet) of temporary stream impacts associated with
improvements to the approaching roadways. These temporary impacts will include removal of
the existing bridge and pavement, culvert excavation, low-flow channel excavation, stream re-
alignment and dewatering as depicted on permit drawing sheet 4 of 5.
Utility Impacts:
The existing sanitary sewer will be in conflict with the proposed culvert bottom slab. The
proposed crossing of Garden Greek is shown on the utility drawing sheet 2 of 3. This new line
will be installed by conventional open cut construction. A profile of the ductile iron gravity
sanitary sewer line is shown on the profile and detail sheet UC-3 of utility drawing sheet 3 of 3.
The new pipe is to be encased in concrete similar to the existing line. Concrete anti-seepage
collars will be placed at each end of the concrete pipe encasement. During construction of the
box culvert, the contractor is to plug the ends of the existing 18' sanitary sewer pipe. There will
be 5 feet of temporary impacts due to the installation of the new the sanitary sewer pipe beneath
the stream bed.
Bridge Demolition
Bridge No. 238 is a one-span structure that consists of a timber floor on I-beams and channels
with anasphalt-wearing surface. The end bents consist of abutments: timber caps on timber posts
and sills. The possibility exists that demolition materials (such as asphalt, concrete rubble, or
portions of the deck timbers) could fall into Garden Creek during demolition. Should this occur,
such materials would be removed as soon as possible. Utilizing best management practices, the
planned removal of this bridge using current bridge demolition methods and guidelines should
result in no temporary fill. There are no interior bents associated with this structure further
reducing the potential for temporary fill.
PROJECT SCHEDULE
The project schedule calls for an August 19, 2008 let date with a review date of July 1, 2008.
FEDERALLY PROTECTED SPECIES
Plants and animals with federal classifications 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. As of January 16, 2008, the
United States Fish and Wildlife Service (USFWS) lists four federally protected species for Burke
Nationwide 13, 23, 33 Permit Application 2 B-4196

County (Table 1). It should be noted that the Bald Eagle was previously listed as "Threatened",
however it was delisted August 8, 2007.

The bald eagle has been delisted from the Endangered Species Act as of August 8, 2007. It is
still protected under the Bald and Golden Eagle Protection Act. A survey was conducted in July
2001. No suitable habitat was observed.
AVOIDANCE, MINIMIZATION AND MITIGATION
Avoidance and Minimization:
Avoidance examines all appropriate and practicable possibilities of averting impacts to "Waters
of the United States." The NCDOT is committed to incorporating all reasonable and practicable
design features to avoid and minimize jurisdictional stages; minimization measures were
incorporated as part of the project design. The use of best management practices for construction
should reduce impacts to plant communities. The following avoidance and minimization
measures will apply to this project.
• Traffic will be detoured off-site during construction. This eliminates the need for a
temporary on-site detour.
• Water will not be directly discharged into Garden Creek via deck drains.
• There will be 2-foot sills in the outer barrels to accommodate for low flow.
In addition, Best Management Practices will be followed as outlined in "NCDOT's Best
Management Practices for Construction and Maintenance Activities".
Compensatory Miti ag tion:
The NCDOT proposes no mitigation for the 81 feet of minimal impacts associated with this
project. There are no HQW, ORW, or Water Supplies and 70 feet of bank stabilization does not
result in loss of waters.
REGULATORY APPROVALS
Section 404 Permit:
It is anticipated that the stream re-alignment will be authorized under Section 404 Nationwide
Permits 13 and 33 (Bank Stabilization and Temporary Construction Access and Dewatering). We
are, therefore, requesting the issuance of Nationwide Permits 13 and 33. All other aspects of this
Nationwide 13, 23, 33 Permit Application 3 B-4196

project are being processed by the Federal Highway Administration as a "Categorical
Exclusion". The NCDOT requests that these activities be authorized by a Nationwide Permit 23.
Section 401 Permit:
We anticipate 401 General Certification numbers 3689, 3701 and 3688 will apply to this project.
We are hereby requesting a water quality certification from DWQ. We are submitting five copies
of this application to the North Carolina Department of Environmental and Natural Resources,
Division of Water Quality, for their review and approval.
This project is located in a trout county; therefore comments from the North Carolina Wildlife
Resources Commission (NCWRC) will be required prior to authorization by the Corps of
Engineers. By copy of this letter and attachment, NCDOT hereby requests NCWRC review.
NCDOT requests that NCWRC forward their comments to the Corps of Engineers and the
NCDOT within 30 calendar days of receipt of this application.
Thank you for your assistance with this project. If you have any questions or need additional
information, please contact Jeremy T. Learner at jtleamer c~dot.state.nc.us or [phone].

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. Alternative 1 was not chosen
because it does not result in the ne_cessarv roadway improvements. Alternative 2 was chosen due
to significant roadway improvements, yet still resulting in an off-site detour. The "do-nothing"
Updated 11/1/2005
Page 9 of 13

alternative was not considered due to it eliminating the use of SR 1506 and closing the bride.
Impacts will be minimized by constructing a 3-barrel concrete reinforced box culvert and
surficial bridge runoff will not be directed into Garden Creek via deck drains.
VIII. Mitigation
DWQ - In accordance with l5A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that maybe appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina (see DWQ website for most current
version.).
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at

INTRODUCTION: Bridge No. 238 is included in the latest approved North Carolina
Department of Transportation (NCDOT) Transportation Improvement Program (TIP) and is
eligible for 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".
I. PURPOSE AND NEED STATEMENT
The NCDOT Bridge Maintenance Unit records for 2004 indicate Bridge No. 238 has a
sufficiency rating of 49.3 out of a possible 100 for a new structure as a result of temporary
rehabilitation. In 2000 the bridge had a sufficiency rating of 39.2 out of a possible 100. The
bridge is considered fiznctionally obsolete due to a deck geometry appraisal of 3 out of 9 for new
bridges and Bridge No. 238 also has a structural appraisal of 4 out of a possible 9 for new
bridges. These ratings are according to Federal Highway Administration (FHWA) standards.
Therefore, it is eligible for FHWA's Highway Bridge Replacement Program.
Bridge No. 238 has timber elements that are forty-nine years old. Timber components have a
typical life expectancy of 40 to 50 years due to the natural deterioration rate of wood.
Rehabilitation of timber components of a structure is generally practical only when a few
members are damaged or prematurely deteriorated. However, past a certain degree of
deterioration, timber components become impractical to maintain, and upon eligibility the
structures are programmed for replacement. Timber components of both the superstructure and
substructure of Bridge No. 238 are experiencing an increasing degree of deterioration that can no
longer be addressed by reasonable maintenance activities. Bridge No. 238 is approaching the end
of its useful life.
Bridge No. 238 currently carries 1,600 vehicles per day with 2,800 vehicles per day estimated for
the year 2025. The substandard clear deck width of 19.2 feet is becoming increasingly
unacceptable and replacement of the bridge should result in safer traffic operations.
II. EXISTING CONDITIONS
The project is located at the intersection of SR 1506 (Garden Creek Church Road) and US 70/
US 221 Business in McDowell County (See Figure 1). The centerline of the unnamed creek
flowing under the existing structure forms a boundary for the City of Marion corporate limits.
Development in the area is commercial and residential in nature.

SR 1506 is classified as a Rural Local in the Statewide Functional Classification System and
is not a National Highway System Route. SR 1506 is located within the Urban Area Boundary of
the Town of Marion. However, it is not a designated Bicycle Route and there is no indication that
an unusual number of bicyclists use this roadway at the project site.
SR 1506 has an 18-foot pavement width with 3-foot grass shoulders in the vicinity of the bridge,
(See Figure 3). The existing bridge is on a tangent. The roadway crown is situated approximately
9.0 feet above the creek bed.
Bridge No. 238 is a one-span structure that consists of a timber floor on I-beams and channels
with anasphalt-wearing surface. The end bents consist of abutments: timber caps on timber posts
and sills. The existing bridge (see Figure 3) was constructed in 1957. The overall length of the
structure is 37 feet. The deck width is 20.1 feet. The posted weight limit on this bridge is 17 tons
for single vehicles (SV's) and 22 tons for truck-tractor semi-trailers (TTST's).
Utilities noted in the vicinity of the bridge include U/G water, gas, and fiber optic lines. There are
also aerial power and telephone lines along the east side of US 221 Business. The fiber optic
lines are aerial crossing the stream and become underground along the north and east side of
SR 1506. There is also a water line along SR 1506 and sanitary sewer near the east end of the
bridge. Utility impacts are anticipated to be high.
The current traffic volume of 1,600 vehicles per day (VPD) is expected to increase to 2,800 VPD
by the year 2025. The projected volume includes one percent truck-tractor semi-trailer (TTST)
and two percent dual-tired vehicles (DT). The speed limit is 25 miles per hour in the project area.
One school bus crosses the bridge twice daily on its morning and afternoon routes.
There were two accidents reported in the vicinity of Bridge No. 23 8 during a prior three-year
period. One of the two crashes was associated with the alignment or geometry of the bridge
approach at the east end. However, the primary cause of the crash was alleged operator error.
III. ALTERNATIVES
A. Project Description
The proposed replacement of the existing bridge is a triple barrel 11-foot wide by 8-foot high
reinforced concrete box culvert. The culvert size is based on preliminary design information and
is set by hydraulic requirements. This structure will be of sufficient length to provide for three
lanes of traffic with curb and gutter on each side of the road. The roadway grade of the new
structure will be approximately the same as the existing grade. The existing roadway will be
realigned to create an improved horizontal alignment at the adjacent intersection. Existing grass
shoulders will be maintained on each side of the road to the east of the existing structure.
2

B. Reasonable and Feasible Alternatives
Two alternates for replacing Bridge No. 238 that were studied in detail aze described below.
Alternate 1
Alternate 1 involves replacement of the existing structure, utilizing the existing roadway
alignment, with athree-ban el 11-foot wide by 8-foot high reinforced concrete box culvert. The
culvert size is based on preliminary design information and is set by hydraulic requirements.
Improvements to the approach roadways will be required for a distance of approximately 30 feet
to the south and approximately 60 feet to the north of the new structure. Two 12-foot lanes would
be created on the structure with roadway widening to a variable width at the intersection of
SR 1506 and US 70/US 221B. A tapered concrete island would be constructed on SR 1506 at the
intersection of SR 1506 and US 70/US 221B separating the entrance and exit lanes of SR 1506.
A retaining wall is proposed at the northwest corner of the structure to stabilize the shoulder of
SR 1506 at that location. Traffic would be detoured off-site during the construction period.
Alternate 2 (Preferred)
Alternate 2 involves replacement of the existing structure along a new roadway alignment
beginning east of the existing structure with athree-barrel 11-foot wide by 8-foot high reinforced
concrete box culvert. This would create an improved horizontal alignment at the intersection of
SR 1506 and US 70/LJS 221B. Improvements to the approach roadways will be required for a
distance of approximately 200 feet to the east and 40 feet to the west of the new structure. Three
12-foot lanes would be created on the eastern approach to the structure resulting in three 12-foot
lanes on the structure terminating in a right and left exit turn lane on SR 1506 and an entrance
lane at the intersection of SR 1506 and US 70/LJS 221 B. Traffic would be detoured off-site
during the construction period.
NCDOT Guidelines for Evaluation of Off-site Detours for Bride Replacement Projects
considers multiple project variables beginning with the additional time traveled by the average
road user as a result of the use of the studied off-site detour. The off-site detour for this project
would include SR 1506, and US 70lUS 221 Business. The detour for the average road user
would result in approximately 2.0 minutes additional travel time (1.2 miles additional travel).
Up to a nine-month duration of construction is expected on this project.
Based on the Guidelines, the criteria above indicate that on the basis of delay alone the detour
is acceptable. McDowell County Emergency Services and McDowell County Schools
Transportation have indicated the detour is acceptable. NCDOT Division 13 has indicated the
condition of all roads, bridges, and intersections on the off-site detour are acceptable without
improvements and Division 13 concurs with the proposed off-site detour.

C. Alternatives Eliminated From Further Consideration
Replace-in-place with a similar structure was not considered as the culvert may be constructed in
a shorter time period, and the culvert is a more cost-effective option.
The "do-nothing" alternative will eventually necessitate closure of the bridge. This is not
acceptable due to the traffic service provided by SR 1506.
"Rehabilitation" of the old bridge is not practical due to its age and the overall deteriorated
condition of the timber components.
Staged Construction is not feasible for this bridge because anoff--site detour is available and
more advantageous.
An on-site detour is not feasible for this bridge because anoff-site detour is available and more
advantageous.
D. Preferred Alternative
Alternate 2 is preferred due to construction and maintenance costs being lower than that of a
bridge or Alternate 1. The initial construction cost will be lower, the maintenance cost of the
culvert will be lower during the comparable life of the structure, and the culvert has a longer life
expectancy than a bridge.
This culvert design creates a shorter structure than Alternate] and will not require a retaining
wall be constructed as does Alternate 1. Therefore, environmental impacts are reduced. Concerns
regarding public safety warrant the construction of the replacement structure and approaches on a
new alignment with US 70/US 221 B. NCDOT Division 13 concurs with the selection of
Alternate 2 as the preferred alternate.
IV. ESTIMATED COSTS
The estimated costs for the two alternates are shown in Table 1.

V. NATURAL ENVIRONMENT
A. Physical Resources
1. Water Resources
Under the federal system for cataloging drainage basins, the drainage basin containing the
project area is designated as USGS Hydrologic Unit 03050101 (the Upper Catawba
drainage basin). Under the North Carolina Division of Water Quality (DWQ) system for
cataloging drainage basins, the drainage basin containing the project area is designated as
Subbasin 03-08-30 (Catawba River Headwaters).
Streams and rivers have been assigned a best usage classification by the North Carolina
Division of Water Quality. The assigned best usage classification reflects water quality
conditions and potential resource usage. Unnamed tributaries receive the same
classification as the named streams to which they flow.
The single water resource located in the project area, an unnamed tributary to the Catawba
River, has no designated DWQ Stream Index Number. The nearest designated water
resource is the Catawba River, which is located approximately 1,100 feet downstream of
the project area. The Catawba River downstream of the project area is designated by DWQ
as Stream Index Number 11-(1). The unnamed tributary to the Catawba River in the
project vicinity has been assigned no primary water resource classification. The Catawba
River downstream of the project area, however, has been assigned a primary water
resource classification of "C" and a supplemental water resource classification of "Tr".
Class "C" refers to waters that are protected for secondary recreation, fishing, wildlife,
fish and aquatic life propagation and survival, agriculture, and other uses found suitable
for Class "C" waters. Secondary recreation includes wading, boating, and other uses
involving human body contact with water where such activities take place in an infrequent,
unorganized, or incidental manner. There are no restrictions on watershed development or types
of discharges in Class "C" waters.
The surface water classification of "Tr" is a "supplemental classification intended to protect
freshwaters for natural trout propagation and survival of stocked trout". As stated in the
standards, this designation affects wastewater quality but not the type of discharges, and there are
no watershed development restrictions except stream buffer zone requirements of the N. C.
Division of Land Resources.
No surface waters classified as High Quality Water (HQW), Water Supplies (WS-1 or WS-11),
or Outstanding Resource Waters (ORW) occur within 0.6 mile of the project area. These findings
are based on review of the most recently updated state-maintained databases as made available
through the date of preparation of this report.
5

Under the NC Unified Watershed Assessment (UWA) program. The Upper Catawba River
Hydrologic Unit (03050101), within the project area, is classified by DWQ as a UWA Category
"II" watershed for nonpoint source pollution. Under this classification, the watershed is identified
as a watershed "meeting goals, including those needing action to sustain water quality" (North
Carolina Department of Environment and Natural Resources (NCDENR) 2000). Currently,
Mackey Creek and Corpening Creek are the only two impaired waters listed within Subbasin
03-08-30. Both creeks are located downstream of the project area and neither creek is located
within the project vicinity.
To minimize potential impacts to water resources in and downstream of the project area,
NCDOT's Best Management Practices for the Protection of Surface Waters will be strictly
enforced during the construction phase of the project (NCDOT, 1997).
2. Biotic Resources
Four discernable terrestrial communities are located within the project area. Three of these
communities have been altered to the extent that they cannot be classified as a natural
community under the Classification of Natural Communities of North Carolina. These
altered communities consist of: (1) altered right-of-way communities, (2) landscaped
areas, and (3) successional sapling and scrub/shrub communities interspersed with open
fields. One community within the project area retains enough of its natural characteristics
to be classified under the classification of Natural Communities of North Carolina. This
natural community consists of a small remnant of a Piedmont/Mountain Bottomland Forest
along the unnamed tributary to the Catawba River just upstream of the existing bridge.
The aquatic community of the project area consists of the unnamed tributary to the
Catawba River below the ordinary high water line. The unnamed tributary to the Catawba
River ranges in width from approximately 10 to 15 feet. The dominant aquatic habitat
within this section of the unnamed perennial stream consists of cobble/boulder substrate.
Gravel and cobble substrate was 40 to 80 percent embedded on the day of investigation.
No aquatic vegetation was observed below the ordinary high water line of the unnamed
perennial stream at the time of the field investigation.
B. Jurisdictional Topics
The following sections provide an inventory of resource areas and species and an assessment of
possible impacts for (1) waters of the United States and (2) rare and protected species. Waters of
the United States and rare and protected species are of particular significance when assessing
impacts because of federal and state mandates that regulate their protection. The following
sections address those measures that will be required in order to comply with regulatory permit
conditions prior to project construction.
6

1. Surface Waters and Wetlands
A small community of hydrophytic vegetation exists on atriangular-shaped terrace (measuring
approximately 15 by 10 by 6.0 feet) at the base of the stream bank, just upstream of the existing
bridge. This hydrophytic vegetation is associated with intermittently flooded and seasonally
saturated, gleyed gravelly soils. It is estimated that .O1 acres of wetlands exist within the project
area. However, there are no wetland impacts associated with the Preferred Alternate. The
unnamed stream is assumed to be classified as R2UBH. Approximately 85 feet of waters
of the United States exist within the area of the Preferred Alternate.
2. Permits
This project maybe processed as a Categorical Exclusion (CE) under Federal Highway
Administration (FHWA) guidelines. US Army Corps of Engineers (USAGE) Nationwide Permit
23 is expected to be used to authorize impacts. Potential impacts to waters of the United States
resulting from the replacement of this bridge are limited to the footprint of the box culvert and
potential fill associated with bridge demolition. The possibility exists that demolition materials
(such as asphalt, concrete rubble, portions of the deck timbers, etc.) could be inadvertently
dropped into waters of the United States during bridge demolition. Should this occur, such
materials would be removed from waters of the United States as soon as possible, where
conditions allow. Utilizing best management practices, the planned removal of this bridge using
current bridge demolition methods and guidelines should result in no temporary fill in the
unnamed creek. There are no interior bents associated with this structure further reducing the
potential for temporary fill.
In addition, a 401 Water Quality Certification from the North Carolina Department of
Environment and Natural Resources, Division of Water Quality (DWQ) will be required for the
project prior to issuance of a Corps of Engineers permit. Section. 404 of the Clean Water Act
requires that the state issue or deny water quality certification for any federally permitted or
licensed activity that may result in a discharge to waters of the United States. Section 401
Certification allows surface waters to be temporarily impacted for the duration of the
construction or other land disturbance. The issuance of a 401 Certification from DWQ is a
prerequisite to issuance of a Section 404 Permit.
3. Federally Protected Species
Plants and animals with federal classifications of endangered (E), threatened (T), proposed
endangered (PE), and proposed threatened (PT) are protected under the provisions of
Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. As of 29
March 2006, the USFWS lists five federally protected species for McDowell County
(Table 2). A review of the North Carolina Natural Heritage Program (NHP) database of
rare species and unique habitats indicates no occurrences of federally protected species in
the project area. No individual organisms, populations, or suitable habitat for any of the
species listed in Table 2 were observed within the project area at the time of site investigation.

Note:
• "Endangered" denotes a species in danger of extinction throughout all or a significant
portion of its range.
• "Threatened" denotes a species likely to become endangered in the foreseeable future
throughout all or a significant portiori of its range.
• "Threatened (S/A)" denotes a species that is treated as a threatened due to its similarity of
appearance to another endangered or threatened species that is listed for protection.
Threatened (S/A) species are not biologically endangered or threatened and are not subject to
section 7 consultation.
VI. HUMAN ENVIRONMENT
A. Section 106 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.
1. Historic Architecture
The State Historic Preservation Office (SHPO) reviewed the subject project and determined that
no surveys are required (see letter dated January 23, 2002).
2. Archaeology
The State Historic Preservation Office (SHPO) reviewed the subject project. There are no known
archaeological sites within the proposed project area, and no further archaeological investigations
need be conducted (see letter dated February 7, 2006).

B. Community Impacts
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 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.
The Farmland Protection Policy Act requires all federal agencies or their representatives to
consider the potential impact to prime farmland with all land acquisitions and construction
projects. 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.
The project will not have a disproportionately high and adverse human health and environmental
effect on any minority or low-income population.
C. Noise & Air Quality
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. 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. Noise levels could increase during construction but will be temporary. 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.
VII. GENERAL ENVIRONMENTAL EFFECTS
The project is expected to have an overall positive impact. Replacement of an inadequate bridge
will result in safer traffic operations.
The bridge replacement will not have an adverse effect on the quality of the human or natural
environment with the use of current North Carolina Department of Transportation standards and
specifications.
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. 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.

McDowell County is a participant in the National Flood Insurance Program. The project is
located in the Catawba River Basin. The majority of the upstream floodplain consists of urban
development. No apparent wetlands were observed in the vicinity of the bridge during the field
investigation. Any shift in alignment will result in an impact area of about the same magnitude. It
is anticipated the proposed project will not have any adverse impacts on the existing floodplain.
VIII. COORDINATION & AGENCY COMMENTS
NCDOT has sought input from the following agencies as a part of project development:
NC Department of Environment and Natural Resources, U.S. Fish & Wildlife Service,
NC Wildlife Resources Commission, North Carolina Department of Cultural Resources (North
Carolina State Historic Preservation Office).
The N.C. Wildlife Resource Commission and U.S. Fish & Wildlife Service, in standardized
letters, stated that they prefer any replacement structure to be a spanning structure.
Response: At smaller stream crossings it is more advantageous to replace bridges with box
culverts. The construction cost of a culvert is less than that of a bridge at the same location;
culverts require less maintenance throughout their service life than bridges; the useful life of a
culvert is longer than that of a bridge. Therefore, where appropriate, NCDOT prefers to use box
culverts to replace bridges.. As there are no protected resources at this site, 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.
IX. PUBLIC INVOLVEMENT
A letter was sent by the NCDOT Location & Surveys Unit to all property owners who might be
directly effected by this project. Property owners were invited to comment. No comments have
been received to date.
As a result of the determination that a favorable off-site detour was available, no newsletter
was sent to homes and businesses along SR 1506. A Citizen's Informational Workshop was
determined to be unnecessary. There is no substantial controversy on social, economic, or
environmental grounds concerning the project.
X. CONCLUSION
On the basis of the above discussion, it is concluded that no substantial adverse environmental
impacts will result from implementation of the project. The project is therefore considered to be
a federal "Categorical Exclusion" due to its limited scope and lack of substantial environmental
consequences.
