Subject: Nationwide 12, 23, and 33 application. Wake County, Replacement of Bridge
No. 124 Over Perry Creek on SR 2006, Federal Aid Project No. BRZ-2006(1),
State Project No. 8.2406901, TIP Project No. B-3529.
Please find enclosed three copies of the project planning report for the above referenced
project. We plan to replace Bridge No. 124 with an 105 ft (32 m) long bridge. The bridge will
be phase-constructed beginning north of the existing structure to allow for maintenance of
traffic on-site. The new roadway cross section will be 52 ft (16 m) wide from face to face of
curbs with gutters. In addition, sidewalks will be constructed on both sides of the bridge.
Approximately 0.25 ac of wetlands will be impacted by this project.
Bridge Demolition
The existing bridge is composed of concrete and timber. There is potential for
components of the deck to be dropped into waters of the U.S. The resulting temporary fill
associated with the concrete deck is approximately 33 yd3. This project can be classified as
Case 2, which allows no work at all in the water during moratorium periods associated with
fish migration, spawning, and larval recruitment into nursery areas. The North Carolina
Wildlife Resources Commission recommends an in-water work moratorium from February 15
to June 15.
Temporary Causeways
There will be 0.031 ac temporary impacts from the construction of temporary rock
causeways in Perry Creek for the construction of Bridge No. 124. Temporary rock causeways
will be required for construction of the interior bents in order to provide for construction
access. The causeways will facilitate the construction of drilled shafts. The causeways will
consist of plain Class II rip rap topped with a layer of Class B rip rap.
Restoration Plan: No permanent fill will result from the subject activity. The materials used as
temporary fill in the construction of the causeway will be removed. The temporary fill areas
will be graded back to the original contours. Elevations and contours in the vicinity of the
proposed causeways are available from the field survey notes.
Schedule for Construction of Causeways: It is assumed that the Contractor will begin
construction of the proposed causeways shortly after the date of availability for the project.
The Let date is September 16, 2003 with a date of availability of October 19, 2003.
Removal and Disposal: The causeways will be removed within 90 days of the completion of
the deck slab for the structure. The temporary rock causeways will be removed by the
Contractor using excavating equipment. All materials placed in the stream by the Contractor
will be removed. The Class II rip rap that is removed may be used on end slopes where Class
II rip rap is required at the discretion of the Engineer. All other materials removed by the
Contractor will be disposed of at an off-site upland location.
Utilities
An existing water line will need to be relocated. The areas of waters of the U.S. to be
disturbed will be limited to the minimum necessary to install the utility line. There will be no
permanent fill in waters of the U.S. resulting from this relocation. Temporary impacts will
result from trenching and laying the line across Perry Creek. As part of the waterline
installation, approximately 20 linear ft (each side) of stream bank will be disturbed. The stream
is approximately 30 ft wide at the point of crossing. This corresponds to a 600 ft2 (0.01 ac)
disturbance area within the stream itself. The method of installation will be left up to the
Contractor. It is assumed that the stream would be partially dammed to progressively open-cut
L the stream and install the pipeline. Upon completing the installation across the stream, the
dams would be removed and the stream would be returned to pre-construction grade, armored
with Class H rip rap.
The City of Raleigh-Utility Department (per Donna Jackson) does not allow for HDPE
(boring underneath the creek); hence, we have been requested by them to open-cut the
proposed water line.
Federally-Protected Species
Plants and animals with federal classifications of Endangered, Threatened, Proposed
Endangered, and Proposed Threatened are protected under provisions of Section 7 and Section
9 of the Endangered Species Act of 1973, as amended. As of January 29, 2003, the Fish and
Wildlife Service (FWS) lists four federally protected species for Wake County (Table 1).
Table 1. Federally-protected species for Wake County.
Common Name Scientific Name Status
Bald eagle Haliaeetus leucocephalus Threatened (proposed for
delisting)
Red-cockaded woodpecker Picoides borealis Endangered
f wedgemussel
k Alasmidonta heterodon Endangered
sumac
7?Mhaux's Rhus michauxii Endangered
Endangered: a taxon "in danger of extinction throughout all or a significant portion of its range.
Threatened: a taxon "likely to become endangered within the foreseeable future throughout all or a significant
portion of its range.
A Biological Conclusion of "No Effect" was reached for these species as reflected in the
attached CE dated April 2000. A re-survey for Michaux's sumac was conducted on August 17,
2001. No specimens of Michaux's sumac were found during this survey. A survey for dwarf
wedgemussel was conducted on July 27, 1999. It was found that suitable habitat for dwarf
wedgemussel is not present within this portion of Perry Creek.
3 Neuse Buffer Impacts
This project is located in the Neuse River Basin; therefore the regulations pertaining to
the Neuse River Buffer Rules will apply. The project consists of a bridge replacement and the
construction of approximately 1,600 feet of roadway approach work. There will be impacts to
the buffers due to bridge construction. No buffer impacts will occur from the roadway
approach work. Impacts have been minimized. In addition, there will be no erosive velocities
entering the buffers (Q10 2.0 ft3/s or less) and all flow will be diffuse. The impacts from bridge
onstruction are 14,792 ft2 (9,171 W in Zone 1 and 5,621 ft in Zone 2) and thus allowable
under the Neuse Buffer Rules. Therefore, no mitigation is required for this project.
Regulatory Approvals
Section 404 Permit: This project is being processed by the Federal Highway Administration as
a "Categorical Exclusion" in accordance with 23 CFR 771.115(b). Therefore, we do not
anticipate requesting an individual permit, but propose to proceed under a Nationwide 12, 23,
and 33 as authorized by Nationwide Permits 12, 23, and 33 (FR number 10, pages 2020-2095;
January 15, 2002).
Section 401 Permit: We anticipate 401 General Certification numbers 3374, 3403, and 3366
will apply to this project. 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.
Riparian Buffer Certification: We request issuance of a Neuse River Riparian Buffer
Certification from the DWQ for impacts to the Neuse Buffers in compliance with the Neuse
River Buffer Rules.
If you have any questions, or need additional information, please contact Matt Haney at (919)
715-1428.

Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): N/A
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):
Size of watershed draining to pond: Expected pond surface area:
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.
Because the bridge will be widened to a multilane facilitv it will be necessarv to extend the
bridge northeast over Perry Creek and into existing wetlands. Impacts are minimized and in
large part avoided by replacing the bridge virtually within the footprint of the existing alignment.
Page 9 of 133
A comprehensive alternatives analysis was completed to determine the most feasible location of
the new bridge.
Mitigation
DWQ - In accordance with 15A 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 March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. 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.
N/A
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of

A municipal agreement will be necessary with the City of Raleigh to
determine a cost-sharing agreement for expenses associated with the
accommodation of the proposed greenway.
At that time, these two branches should confer regardin the use of the
Bridge Replacement funds for the entire project. The portion o' f the bridge
needed to accommodate a two-lane roadway will be funded with Bridge
Replacement funds. Funding for the additional width will be determined at a
future date.

Federal Project BRZ-2006 (1)
State Project 8.2406901
TIP No. B-3529
Bridge No. 124 is located in Wake County over Perry Creek. It is programmed in
the 2000-2006 Transportation Improvement Program (TIP) as a bridge replacement
project. This project is part of the Federal Highway Bridge Replacement and
Rehabilitation Program (HBRRP) and has been classified as a "Categorical Exclusion".
No substantial enviromnental impacts are expected. .
1. SUMMARY OF RECOMMENDATIONS
Bridge No. 124 will be replaced as recommended in Alternate 1 with a new
105-foot (32 m) long bridge. The new bridge will be phase constructed beginning north
of the existing structure (see Figure 2). The new roadway cross section on the bridge will
be 52 feet (15.8 m) wide from face to face of curbs with gutters. The curb and gutter
section will transition to a shoulder section on the roadway approaches. In addition,
sidewalks will be constructed on both sides of the bridge. Traffic will be maintained on
the existing structure until 2'/z lanes are completed to the north side. Traffic will then be
shifted to the north while the remainder of the bridge is built. The new roadway cross
section will accommodate two lanes of traffic initially with the capacity to handle four
lanes in the future.
There will be approximately 800 feet (244 m) of new approach work to the east
and 800 feet (244 m) of new approach work to the west. The roadway cross section on
the immediate approaches will be 52 feet (15.8 m) wide from face to face of curbs with
gutters for approximately 200 feet (60.9 m) on either side of the bridge. From this point,
the approach roadway cross section will be 48 feet (14.6 m) wide plus 4-foot (1.2-m)
paved shoulders on both sides of the roadway. The approach roadway cross section will
then transition to the existing roadway width. The total shoulder width through this
section of approach roadway will be 8 feet (2.4 m), including 4 feet (1.2 m) of paved
shoulder and 4 feet (1.2 m) of grassed shoulder. Based on preliminary design, the design
speed wilfbe approximately 50 mph (80 km/h).
In addition, the proposed bridge replacement will accommodate clearance for the
City of Raleigh's proposed greenway located along Perry Creek. The clearance required
for the greenway will increase the bridge length from 95 feet (30 m) to the proposed
105 feet (32 m).
The estimated cost of the project is $1,560,000 including $1,500,000 in
construction costs and $60,000 in right of way costs. The estimated cost shown in the
2000-2006 TIP is $737,000.
II. ANTICIPATED DESIGN EXCEPTIONS
Based on preliminary analysis, a design exception will not be required for this
project.
III. EXISTING CONDITIONS
SR 2006 (Perry Creek Road) is classified as an Urban Local Route in the Statewide
Functional Classification System. SR 2006 connects US 401 with US 1 in the
northeastern area of Raleigh. Currently the traffic volume is 9000 vehicles per day (VPD)
and projected at 24,000 VPD for the year 2025. Approximately 1 percent of the traffic is
truck-tractor semi-trailers (TTST) and 2 percent of the traffic is dual-tired vehicles (DT).
The design hourly.volume is 9 percent and the directional split is 60 percent. There is a
45-mph (70-km/h) posted speed limit in the vicinity of the bridge.
The existing bridge was completed in 1952. The bridge contains a four-span
superstructure, including a concrete deck with timber girders.. The deck is 70 feet
(21.3 m) long and 25 feet (7.6 m) wide. The substructure is composed of timber end and
interior bents. There is approximately 15 feet (4.6 m) of vertical clearance between the
floorbeams of the bridge.deck and streambed. There are two lanes of traffic on the
bridge.
According to Bridge Maintenance Unit records, the sufficiency rating of the
bridge is 11.2 out of a possible 100. Presently the bridge is posted with weight
restrictions of 17 tons for single vehicles and 24 tons for truck-tractor semi-trailers.
Vertical alignment is good and horizontal alignment is fair in the bridge vicinity.
The pavement width on the approaches to the existing bridge is 20 feet (6 m). Shoulders
on the approaches of the bridge are approximately 4 feet (1.2.m) wide.
The Traffic Engineering Branch indicates that 16 accidents have been reported
during a recent three-year period in the vicinity of the project. The assortment of
accidents occurred-due to a variety of reasons. None involved the bridge.
There are 24 daily. school bus crossings over the studied bridge. According to the
Transportation Director for Wake County, closing the road would be a major burden.
Carolina Power and Light (CP&L) has multiple electrical lines along the south side of
SR 2006. Cable Television cables are attached to the CP&L poles. In addition, the City of
Raleigh has a 16-inch (40-cm) water line along the north side of SR 2006 crossing SR 2006
approximately 130 feet (40 m) west of the bridge. The City of Raleigh also owns a 30-inch
(76-cm) sanitary sewer outfall line approximately 150 feet (45.7 m) east of the bridge. Also,
Bell South owns underground cables along the south side of SR 2006.
IV. PROPOSED ALTERNATIVES
There are two "build" options considered in this document as follows:
Alternate 1: (Recommended) Bridge No. 124 will be replaced with a 105-foot (32-m)
long bridge. The bridge will be phase constructed beginning north of the
existing structure to allow for maintenance of traffic on-site. The new
roadway cross section will be 52 feet (15.8 m) wide from face to face of
curbs with gutters. In addition, sidewalks will be constructed on both
sides of the bridge. The design speed will be approximately 50 mph
(80 km/h).
Alternate 2: Bridge No. 124 would be replaced with a 105-foot (32-m) long bridge.
The bridge would be phase constructed beginning north of the existing
structure to allow for maintenance of traffic on-site. The new roadway
cross section would be 64 feet (19.5 m) wide from face to face of curbs
with gutters. In addition, sidewalks would be constructed on both sides of
the bridge. The design speed would be approximately 50 mph (80 km/h).
"Do-nothing" is not practical; requiring the eventual closing of the road as the
existing bridge completely deteriorates. Rehabilitation of the existing deteriorating
bridge is neither practical nor economical.
An alternative of providing a basic two-lane shoulder facility with sidewalk on the
north side of the bridge was considered. This alternate was rejected due to the obvious
need for a future multi-lane facility.

VI. RECOMMENDED IMPROVEMENTS
Bridge No. 124 will be replaced as recommended in Alternate 1 with a 105-foot
(32-m) long bridge to be phase constructed on the north side of the existing structure (see
Figure 2). The new roadway cross section will be 52 feet (15.8 m) wide from face to face
of curbs with gutters. The curb and gutter section will transition to a shoulder section on
the approaches. In addition, sidewalks will be constructed on both sides of the bridge.
The bridge will be phase constructed to allow for maintenance of traffic on-site. The
roadway cross section will provide for two lanes of traffic initially.
There will be approximately 800 feet (244 m) of new approach work to the east
and 800 feet (244 m) of new approach work to the west. The roadway cross section on
the immediate approaches will be 52 feet (15.8 m) wide from face to face of curbs with
gutters for approximately 200 feet (60.9 m) on either side of the bridge. From this point,
the approach roadway cross section will be 48 feet (14.6 m) wide plus 4-foot (1.2-m)
paved shoulders on both sides of the roadway. The approach roadway cross section will
then transition to the existing roadway width. The total shoulder width through this
section of approach roadway will be 8 feet (2.4 m), including 4 feet (1.2 m) of paved
shoulder and 4 feet (1.2 m) of grassed shoulder. Based on preliminary design, the design
speed will be approximately 50 mph (80 km/h).
Alternate I is recommended because the proposed four-lane section on the bridge
accommodates future traffic volumes and requires the least cost of the alternates
considered. Although the 1994 Statewide Thoroughfare Plan for Wake County
recommends a five-lane section along SR 2006, only four lanes are needed across the
bridge. A center turn-lane will not be required in the future on the immediate approaches
to the bridge since the land is not developable.
The multi-lane bridge is justifiable due to the existing and planned development
in the anticipated highest growth area in the City of Raleigh. Large subdivisions are
located east and west of the bridge along SR 2006. Dense urban development is located
immediately south of SR 2006. The Northern Wake Expressway and the Triangle Towne
Center regional mall are under construction within a mile. The mall is accessible from
SR 2006. The Neuse Crossroads development is under construction on SR 2006 west of
the bridge. This includes a shopping center, an 800-student elementary school, 252
single-family units, and 1116 condominiums. A proposed Wake Technical Community
College is planned nearby. Much of the above mentioned development will have
entrances "onto SR 2006.
Coordination with the City of Raleigh was accomplished in order to comply with
their transportation plans in the bridge vicinity. The City of Raleigh has a sidewalk
policy, which states that widening a thoroughfare with significant development along the
road requires sidewalks on both sides of the roadway. Currently, the City has plans to
widen SR 2006 to a multi-lane facility in the future to accommodate the tremendous
traffic growth in the bridge vicinity. In order to comply with the City's future widening
project, sidewalks will be installed on both sides of the bridge. Justification for the
sidewalks is due to the high-density development underway which will generate
pedestrian activity. The WRAL Soccer Field Complex is located'/4 mile west of the
bridge.
In addition, the City of Raleigh acquired right-of-way up to the north and south
sides of the bridge for a proposed greenway located along Perry Creek. NCDOT will
accommodate the greenway under the northwest side of the bridge, which increases the
bridge length from 95 feet (30 m) to the proposed 105 feet (32 m). This accommodation is
contingent upon a municipal agreement with the City- of Raleigh to determine a cost-
sharing agreement for expenses associated with the increased bridge length.
VII. ENVIRONMENTAL EFFECTS
A. GENERAL
This project is expected to have an overall positive impact. Replacement of an
inadequate bridge will result in safer traffic operations.
This project is considered to be a "Categorical Exclusion" due to its limited scope
and insignificant environmental consequences.
This bridge replacement will not have a substantial adverse effect on the quality
of the human or natural environment. Environmental commitments listed on the Project
Commitments sheet of this document will be implemented in addition to the use of
current NCDOT standards and specifications.
The project is not in conflict with any plan, existing land use, or zoning
regulation. No change in land use is expected to result from construction of this project.
There are no hazardous waste impacts.
No adverse effect on families or communities is anticipated. Right-of-way
acquisition will be limited.
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.
There are no publicly owned parks, recreational facilities, or wildlife and
waterfowl refuges of national, state, or local significance in the vicinity of the project.
This project will not impact any resource protected by Section 4(f) of the U. S.
Department of Transportation Act of 1966.
The proposed bridge replacement project will not raise the existing flood levels or
have any significant adverse effect on the existing floodplain.
Utility impacts are considered to be moderate for the proposed project.
B. AIR AND NOISE
This project is located in Wake County, which is within the Raleigh-Durham non-
attainment area for ozone (03) and carbon monoxide (CO) as defined by the
Environmental Protection Agency (EPA). The 1990 Clean Air Act Amendments
(CAAA) designated this area as a "moderate" non-attainment area for 03 and CO.
However, due to improved monitoring data, this area was re-designated as "maintenance"
for 03 on June 17, 1994. Section 176(c) of the CAAA requires that transportation plans,
programs, and projects conform to the intent of the state air quality implementation plan
(SIP). The current SIP does not contain any transportation control measures for Wake
County. The Capital Area 1995 Transportation Improvement Program (TIP) has been
determined to conform to the intent of the SIP. The MPO approval date for the TIP is
April 21, 1999. The USDOT approval date of the TIP is July 30, 1999. The current'
conformity determination is consistent with the final conformity rules found in CFR Part
51. There have been no significant changes in the project design concept or scope. as
used in the conformity analysis;
The impact on air quality will be insignificant. If the project disposes of
vegetation by burning, all burning shall be done in accordance with applicable local laws
and regulations of the North Carolina SIP for air quality in compliance with 15 NCAC
2D.0520. This evaluation completes the assessment requirements of the 1990 Clean Air
Act amendments and the National Environmental Policy Act. This project requires no
additional reports.
The project will not substantially increase traffic volumes. Therefore, it will not
have substantial impact on noise levels. Temporary noise increases may occur during
construction.
C. LAND USE & FARMLAND EFFECTS
In the vicinity of this project, Wake County has no zoning. This project will
impact no soils considered to be prime or important farmland.
D. HISTORICAL EFFECTS & ARCHAEOLOGICAL EFFECTS
On March 8, 1999, the State Historic Preservation Office (SHPO) reviewed the
subject project. Subsequently, the SHPO recommended no architectural or
archaeological surveys be conducted in connection with this project (see attachment).
E. NATURAL RESOURCES
1. PHYSICAL RESOURCES
Soil and water resources, which occur in the study area, are discussed below.
Soils and availability of water directly influence composition and distribution of flora and
fauna in any biotic community.
The project study area lies within the Piedmont Physiographic Province. The
topography in this section of Wake County is characterized by gently rolling hills, which
are dissected by fairly wide flood plains bordered by steep slopes. Topography in the
project area is relatively flat since it is located in a wide flood plain area associated with
Perry Creek. Project elevation is approximately 190.0 ft (58.0 m) above mean sea level
(msl).
SOILS
. Five soil map units occur within project boundaries: Wehadkee and Bibb soils,
two types of Appling sandy loams, Wahee fine sandy loam, and Altavista fine sandy
loam. The Wehadkee and Bibb soils are the dominant soil types associated with the
project study area and are so similar in use and management that they have been mapped
together as an undifferentiated unit. The remaining soil units may be encountered during
project construction. Table 2 lists study area soils and their characteristics.

Wehadkee and Bibb soils, with 0-4 percent slopes, are located along the
floodplain of Perry Creek. The water table may be at the surface for periods of as much
as six months. They are poorly drained soils, and surface runoff is slow to ponded.
Infiltration is fair for the Wehadkee soil and good for the Bibb soil. Permeability is
moderate to moderately rapid. Flooding occurs very frequently for extended periods.
Wehadkee and Bibb soils are listed as hydric soils.
Wehadkee and Bibb soils are low in natural fertility and may be strongly acid to
very strongly acid. Cultivated crops are difficult to grow because adequate drainage
requires both surface drainage and subsurface drainage. Flooding and ponding are major
limitations for these soils.
. Appling sandy loam, with 6-10 percent and 10-15 percent slopes, are well drained
soils that occur on narrow side slopes in the uplands. Permeability is moderate, and
surface runoff is rapid to very rapid. Infiltration is fair to good.
Appling_soils are low in natural fertility, however, they are well suited to locally
grown crops. These soils are strongly acid. About one-third of the acreage is cultivated
or in pasture, and the remainder is forested. Intensive practices that effectively control
runoff and erosion are required if cultivated crops are grown. Erosion is a major
limitation for these soils. ,
Wahee fine sandy loam, with 0-2 percent slopes, is a somewhat poorly drained
soil that occurs on low stream terraces. Infiltration is good, and surface runoff is slow to
ponded. Permeability is slow, and the seasonal high water table is at a depth of about
1.5 ft (0.5 m).
The natural fertility of Wahee soils is medium, and the soils are strongly acid.
Most of the acreage is in forest, however, if properly drained it may be cultivated or in
pasture. Wetness and the slowly permeable subsoil are the main limitations for this soil.
Wahee fine sandy loam is listed as having hydric inclusions of Roanoke.
Altavista fine sandy loam, with 0-4 percent slopes, is a moderately well drained
soil that occurs on low stream terraces. Infiltration is good, and surface runoff is slow to.
medium. Permeability is moderate, and the seasonal high water table is at a depth of
approximately 2.0 ft (0.6 m).
Altavista soils are low in natural fertility, however this soil is well suited to most
of the locally grown crops. These soils may range from medium acid to strongly acid. A
small acreage is occupied by trees, but it is mainly used for row crops or pasture.
Infrequent flooding does -occur, but the floodwaters remain for short periods. Altavista
fine sandy loam is listed as having hydric inclusions of Roanoke.
Soil core samples taken throughout the project area revealed soils with a silty
texture. The soils did exhibit hydric conditions, such as low chroma colors. in low areas
of the floodplain and in the herbaceous wetland. Therefore, hydric soil indicators, as
defined in the "Corps of Engineers Wetland Delineation Manual". 1987, were observed
within the project study area.
WATER RESOURCES
. This section contains information concerning those water resources likely to be
impacted by the project. Water resource information encompasses physical aspects of the
resource, its relationship to major water systems, Best Usage Standards and water quality
of the resources. Probable impacts to these water bodies are also discussed, as are means
to minimize impacts.
Waters Impacted and Characteristics
Perry Creek will be the only surface water resource directly impacted by the
proposed project (Figure 2). Perry Creek is located in sub-basin.03-04-02 of the Neuse
River Basin. Perry Creek is a tributary to the Neuse River, and has its confluence with
the river approximately 0.6 mi (1.0 km stream channel distance) downstream of Bridge
No. 124.
At Bridge No. 124, the channel of Perry Creek is approximately 45.0 ft (13.7 m)
wide and has an average depth of 6.0 ft (1,8 m). The average baseflow width is 14.0 ft
(4.3 m), and the average depth of the baseflow is 5.0 in (12.7 cm). The substrate is
composed of sand and gravel. Sand deposits have caused the formation of numerous
shoals. Pools of stagnant water with iron bacteria, as well as filamentous algae, horsehair
algae, (Pithophora sp.) are present.
Approximately 50.0 ft (15.2 m) from the center of the road, on the southeast
comer of Bridge No. 124, there is a small unnamed tributary (UT) flowing into Perry
Creek. The channel width is approximately 4.0 ft (1.2 m), and the depth is 2.0 ft (0.6 m).
The baseflow width is approximately 1.5 ft (0.5 m), and the baseflow depth is 2.0 in
(5.1 em). The UT is approximately 10.0 ft (3.1 m) out of the proposed ROW. As long as
NCDOT stays within the proposed ROW of 120.0 ft (36.6 m), project construction should
not infringe on the UT.
Best Usage Classification
Streams are assigned a best usage classification by the DWQ. The classification
of Perry Creek [index no. 27-25-(2)] is C NSW. Class C uses include aquatic life
propagation and survival, fishing, wildlife, secondary recreation and agriculture. The
supplemental classification of NSW denotes Nutrient Sensitive Waters which require
limitations on nutrient inputs. The Falls Lake Protected Watershed Area is located
approximately 3.8 mi (6.1 km) northwest of the project area. The project area is not
located in a water supply watershed.
Neither High Quality Waters (HQW), Water Supplies (WS-I: undeveloped
watersheds or WS-II: predominately undeveloped watersheds) nor Outstanding Resource
Waters (ORW) occur within 1.0 mi (1.6 km) of project study area.
Water Qualitti
The DWQ has initiated a whole basin approach to water quality management for
the 17 river basins within the state. To accomplish this goal the DWQ collects biological.
chemical and physical data that can be used in basinwide assessment and planning. All
basins are reassessed every five years. Prior to the implementation of the basin-wide
approach to water quality management, the Benthic Macroinvertebrate Ambient Network
(managed by the DEM) assessed water quality by sampling for benthic macroinvertebrate
organisms at fixed monitoring sites throughout the state. A Benthic Macroinvertebrate
data site is located at Bridge No. 124. This site was sampled in July of 1995 and received
a rating of Fair.
Many benthic macroinvertebrates have stages in their life cycle that can last from
six months to a year, therefore, the adverse effects of a toxic spill will not be overcome
until the next generation. Different taxa of macroinvertebrates have different tolerances
to pollution, thereby, longterm changes in water quality conditions can be identified by
population shifts from pollution sensitive to pollution tolerant organisms (and vice versa).
Overall, the species present, the population diversity and the biomass are reflections of
long term water quality conditions.
Point source dischargers located throughout North Carolina are permitted through
the National Pollutant Discharge Elimination System (NPDES) Program. Any discharger
is required to register for a permit. Three permitted dischargers are located within 1.0 mi
(1.6 km) of Bridge No. 124 (Table 3).

Nonpoint source discharge refers to runoff that enters surface waters through
stormwater or snowmelt. Agricultural activities may serve as a source for various forms
of nonpoint source pollutants. Land clearing and plowing disturb soils to a degree where
they are susceptible to erosion, which can lead to sedimentation in streams. Sediment is
the most widespread cause of nonpoint source pollution in North Carolina. Pesticides,
chemical fertilizers, and land application of animal wastes can be transported via runoff
to receiving streams and potentially elevate concentrations of toxic compounds and
nutrients. Animal wastes can also be a source of bacterial contamination and elevate
biochemical oxygen demand (BOD). Drainage ditches on poorly drained soils enhances
the transportation of stormwater into surface waters (DEM, 1993).
Summary of Anticipated Impacts
Replacing an existing structure in the same location without constructing a detour
bridge during construction is almost always preferred. It poses the least risk to aquatic
organisms and other natural resources. Bridge replacement on new location usually
results in more severe impacts. Utilizing the full ROW width of 120.0 ft (36.6 m).
.anticipated impacts to Perry Creek. will be 120.0 ft (36.6 m) for each alternate. Usually.
project construction does not require the entire ROW; therefore. actual impacts may be
considerably less.
Project construction may result in the following impacts to surface waters:
1. Increased sedimentation and siltation from construction and/or erosion.
2. Changes in light incidence and water clarity due to increased sedimentation and
vegetation removal.
Alteration of water levels and flows due to interruptions and/or additions to
surface and ground water flow from construction.
4. Changes in water temperature due to streamside vegetation removal.
Increased nutrient loading during construction via runoff from exposed areas.
6. Increased concentration of toxic compounds from highway runoff, construction
and toxic spills.
Precautions must be taken to minimize impacts to water resources in the study
area, NCDOT's Best Management Practices (BMP) for the Protection of Surface Waters
must be strictly enforced during the construction stage of the project. Guidelines for
these BMPs include, but are not limited to: minimizing built upon area and diversion of
stormwater away from surface water supply waters as much as possible. Provisions to
preclude contamination by toxic substances during the construction interval must also be
strictly enforced.
The Wildlife Resource Commission (WRC) indicated that Perry Creek supports
an anadromous fish-spawning run due to recent dam removals on the Neuse River. They
requested that NCDOT follow the officially adopted "Stream Crossing Guidelines for
Anadromous Fish Passage" and that no in-water work occur from February 15 to June 15.
II. BIOTIC RESOURCES
Biotic resources include aquatic and terrestrial ecosystems. This section describes
those ecosystems encountered in the study area, as well as, the relationships between
fauna and flora within these ecosystems. Composition and distribution of biotic
communities throughout the project area are reflective of topography, hydrologic
influences and past and present land uses in the study area. Descriptions of the terrestrial
systems are presented in the context of plant community classifications and follow
descriptions presented by Schafale and Weakley (1990) where possible. Dominant flora
and fauna observed, or likely to occur, in each community are described and discussed.
Scientific nomenclature and common names (when applicable) are provided for
each animal and plant species described. Plant taxonomy generally follows Radford, et
al. (1968). Animal taxonomy follows Martof, et al. (1980), Menhenick (1991), Potter, et
al. (1980), and Webster, et al. (1985). Subsequent references to the same organism will
include the common name only. Fauna observed during the site visit are denoted with an
asterisk (*). Published range distributions and habitat analysis are used in estimating
fauna expected to be present within the project area.
10
TERRESTRIAL COMMUNITIES
The study area appears to have been previously disturbed. Five distinct terrestrial
communities (Figure)) are identified in the project study area: Mixed Pine Hardwood
forest, Alluvial forest.. a Depressional Wetland, a Herbaceous Wetland. and
maintained/disturbed areas. Community boundaries within the study area are well
defined without a significant transition zone between them. Faunal species likely to
occur within the study area will exploit all of the communities for shelter and foraging
opportunities or as movement corridors.
Mixed Pine Hardwood Forest
The mixed pine hardwood forest is present in the upland areas adjacent to the
Perry Creek floodplain. The transition from mixed pine hardwood forest to the
surrounding communities is abrupt due to the change in vegetation and road shoulder
maintenance activities.
The canopy is primarily composed of American elm (Ulmus americana), winged.
elm (U. alata), sycamore (Platanus occidentalis), mockemut hickory (Carya tomentosa),
water oak (Quercus nigra), white oak (Q. alba), sweetgum (Liquidambar styraciflua),
black gum (Nyssa sylvatica), loblolly pine (Pinus taeda), red mulberry (Morus rubra),
and red maple (Acer rubrum). The shrub layer consists of saplings of the canopy trees,
Chinese privet (Ligustrum sinense), and southern arrowwood (Viburnum dentatum).
Virginia creeper (Parthenocissus quinquefolia), poison ivy (Toxicodendron radicans),
ground ivy (Glecoma hederacea), and greenbrier (Smilax rotundifolia) comprise the vine
layer of this community.
Alluvial Forest
The alluvial forest is present along the Perry Creek corridor. The hydrology of
the alluvial forest is driven by intermittent flooding during high flow periods. Periodic
flooding provides nutrient input through sediment deposition making this system very
productive. However, periodic flooding can also be a destructive factor during large
storm events by undercutting banks and eroding soils.
The canopy is primarily composed of river birch (Betula nigra), green ash
(Fraxinus pennsylvanica), water oak, and sweetgum. The shrub layer consists of saplings
of the canopy trees, boxelder (Acer negundo), ironwood (Carpinus caroliniana), and
Chinese privet. Herbs within the alluvial forest include: dayflower (Commelina sp.),
pokeweed (Phytolacca americana), river oats (Chasmanthium latifolium), and giant cane
(Arundinaria gigantea). Virginia creeper, poision ivy, muscadine grape (Vitis
rotundifolia), and greenbrier comprise the vine layer of this community.
Depressional Wetland
A depressional wetland occurs inside the alluvial forest on the northeast side of
the existing bridge. This open water wetland is approximately 30.0 ft (9.1 m) long and
25.0 ft (7.6 m) wide. On November 17, 1999, the water depth was approximately 1.0 ft
(0.3 m). This depressional wetland was void of vegetation due to the ephemeral nature of
the pool.
On the northwest side of the existing bridge is another depressional wetland. It
lies outside of the project boundaries. As long as project construction remains inside the
proposed ROW, this wetland should not be impacted.

Herbaceous Wetland
A herbaceous wetland occurs on the northeast side of the bridge in between the
alluvial forest and the mixed pine hardwood forest. Herbs within the wetland include:
rush (Juncus sp.), false nettle (Boehmeria cylindrica), sedge (Carer sp.). Japanese grass
(Microstegium vimineum), goldenrod (Solidago sp.), beggar ticks (Bidens sp.), dayflower,
woolgrass (Scirpus cyperinus), and smartweed (Polygonum sp.). Sycamore. red maple,
and sweetgum occur along the perimeter.
Maintained/Disturbed Community
The maintained/disturbed community includes road shoulders along SR 2006 and
are present along the entire length -of the project and a residential area located southeast of
the existing bridge. Flora within this periodically maintained community includes: fescue
(Festuca spp.), crab grass (Digitaria spp.), narrow leaf plantain (Plantago lanceolata),
poison ivy, trumpet creeper (Campsis radicans), ragweed (Ambrosia sp.), Virginia
creeper, blackberry (Rubus sp. ), greenbrier, Queen Anne's lace (Daucus carota),
Japanese honeysuckle (Lonicera japonica), fox grape (Vitis labrusca), muscadine grape,
water oak, sapling trees of winged elm, black cherry, and sweetgum. The residential
community includes Southern magnolia (Magnolia grandiflora), Leyland cypress (X
Cupressocyparis leylandii), hemlock (Tsuga canadensis), white oak, holly (Ilex sp.),
azalea (Rhododendron sp.), loblolly pine, mimosa (Albizia julibrissin), bead grass
(Paspalum sp.), and crab grass. The width of the road shoulder varies between 10.0 and
15.0 ft (3.1 and 4.6 m).
Wildlife
Wildlife associated with the communities present within the project vicinity
include: white-tailed deer (Odocoileus virginianus), eastern mole (Scalopus aquaticus),
opossum (Didelphis virginiana), meadow vole (Microtus pennsylvanicus), muskrat*
(Ondatra zibethicus), gray squirrel* (Sciurus carolinensis), beaver (Castor canadensis),
and raccoon (Procyon lotor). White-tailed deer will use these communities for cover and
will forage on twigs and leaves as well as mast.
The wetter areas such as the herbaceous wetland and the alluvial forest may be
inhabited by reptiles and amphibians such as eastern box turtle (Terrapene c. carolina),
ground skink (Sincella lateralis), Eastern garter snake (Thamnophis sirtalis), spotted
salamander (Ambystoma maculatum), and spring peeper (Hyla crucifer).
Avian species utilizing the project vicinity include: red-shouldered hawk (Buteo
lineatus), blue jay (Cyanocitta cristata), northern cardinal (Cardinalis cardinalis), .
rufous-sided towhee (Pipilo erythrophthalmus), summer tanager, (Piranga rubra), tufted
titmouse (Parus bicolor), white-eyed vireo (Vireo griseus), and red-eyed vireo (Vireo
olivaceus).
The maintained habitat within the project area is surrounded by extensive forested
areas and represents only a minor constituent of a larger community structure within the
project vicinity. Therefore, faunal species frequenting the maintained community will be
largely those species inhabiting the adjacent communities.
AQUATIC COMMUNITIES
One aquatic community, Perry Creek, will be impacted by the proposed project.
Physical characteristics of the water body and condition of the water resource influence
12
faunal composition of aquatic communities. Terrestrial communities adjacent to a vvater
resource also greatl}., influence aquatic communities. No submersed or emergent aquatic
vegetation was observed within this section of Perry Creek.
Vegetation along the streambank includes jewel-weed (Impatiens spp.). Japanese
grass, asiatic day flower (Murdannia keisak), false nettle, river oats, Chinese privet.
poison ivy, greenbrier, blackberry, rush, rose mallow (Hibiscus moscheutos), and cardinal
flower (Lobelia cardinalis).
Fauna associated with these aquatic communities includes various invertebrate
and vertebrate species. Fish species likely to occur in Perry Creek include creek chub
(Semotilus atromaculatus), pumpkinseed sunfish (Lepomis gibbosus), redbreast sunfish
(L. auritus), bluegill sunfish (L. macrochirus), tessellated darter (Etheostoma olmstedi),
and yellow bullhead catfish (Ameiurus natalis). Invertebrates that would be present
include: various species of caddisflies (Trichoptera), mayfly (Ephemeroptera), crayfish
(Decapoda), water striders* (Aquarius sp.), whirligig beetles* (Gyrinidae), water
spiders* (Dolomedes sp.), and dragonflies* and damselflies* (Odonata). Mollusks
identified in Perry Creek includes two species of freshwater mussels* (Elliptio spp.),
asiatic clams* (Corbicula fluminea), and a snail* (Physella sp.). The snapping turtle
(Chelydra serpentina), pickerel frog (Rana palustris), and northern water snake (Nerodia
sipedon) are common permanent residents to this community.
SUMMARY OF ANTICIPATED IMPACTS
Construction of the subject project will have various impacts on the biotic
resources described. Any construction related activities in or near these resources have
the potential to impact biological functions. This section quantifies and qualifies impacts
to the natural resources in terms of area impacted and ecosystems affected. Temporary
and permanent impacts are considered here as well.
Calculated impacts to terrestrial resources reflect the relative abundance of each
community present within the study area. Project construction will result in clearing and
degradation of portions of these communities. Table 4 summarizes potential quantitative
losses to these biotic communities, resulting from project construction. Estimated
impacts are derived using the entire proposed ROW width of 120.0 ft (36.6 m). The
paved roadway width of 24.0 ft (7.3 m) has been excluded from the impact calculations.
Usually, project construction does not require the entire ROW, therefore, actual impacts
may be considerably less.

13
Plant communities found within the proposed project area serve as nestin?(I and
sheltering habitat for various wildlife. Replacing Bridge No. 124 and its associated
improvements will reduce habitat for faunal species, thereby diminishing faunal numbers.
However, due tq the size and scope of this project, it is anticipated that impacts to fauna
will be minimal.
Areas modified by construction (but not paved) will become road shoulders and
early successional habitat. Reduced habitat will displace some wildlife further from the
roadway while attracting other wildlife by the creation of more early successional habitat.
Animals temporarily displaced by construction activities will repopulate areas suitable for
the species.
Aquatic communities are sensitive to even small changes in their environment.
Stream channelization, scouring, siltation, sedimentation and erosion from construction-
related work will effect water quality and biological constituents. Although direct
impacts may be temporary, environmental impacts from these construction processes may
result in long term or irreversible effects.
Impacts often associated with in-stream construction include increased
channelization and scouring of the streambed. In-stream construction alters the stream
substrate and may remove streamside vegetation at the site. Disturbances to the substrate
will produce siltation, which clogs the gills and/or feeding mechanisms of benthic
organisms (sessile filter-feeders and deposit-feeders), fish and amphibian species.
Benthic organisms can also be covered by excessive amounts of sediment. These
organisms are slow to recover or repopulate a stream.
The removal of streamside vegetation and placement of fill material at the
construction site alters the terrain. Alterations of the streambank enhances the likelihood
of erosion and sedimentation. Revegetation stabilizes and holds the soil thus mitigating
these processes. Erosion and sedimentation carry soils, toxic compounds and other
materials into aquatic communities at the construction site. These processes magnify
turbidity and can cause the formation of sandbars at the site and downstream, thereby
altering water flow and the growth of vegetation. Streamside alterations also lead to
more direct sunlight penetration and to elevations of water temperatures, which may
impact many species.
III. JURISDICTIONAL TOPICS
This section provides descriptions, inventories and impact analysis pertinent to
two important issues--Waters of the United States and rare and protected species.
WATERS OF THE UNITED STATES
Surface waters and wetlands fall under the broad category of "Waters of the
United States," as defined in Section 33 of the Code of Federal Register (CFR) Part
328.3. Wetlands, defined in 33 CFR 328.3, are those areas that are inundated or saturated
by surface or ground water at a frequency and duration sufficient to support, and under
normal circumstances do support, a prevalence of vegetation typically adapted to life in
saturated conditions. Any action that proposes to place fill into these areas falls under the
jurisdiction of the U.S. Army Corps of Engineers (COE) under Section 404 of the Clean
Water Act (33 U.S.C. 1344).
14
Characteristics of Wetlands and Surface Waters
Potential wetland communities were investigated pursuant to the 1987 "Corps of
Engineers Wetland Delineation Manual". The three-parameter approach is used where
hydric soils, hydrophytic vegetation and prescribed hydrologic characteristics must all be
present for an area to be considered a wetland.
Wetlands are present within the project area, and are associated with the alluvial
forest (Figure 2). The wetlands can be described as palustrine forested broad-leaved
deciduous seasonally flooded (PFO1 C, Cowardin, et al.), or piedmont/low mountain
alluvial forest (Schafale and Weakley, 1990). Soils within the wetland areas have a silty
texture and a Munsell color notation of l OYR 5/1. Mottles found in the soils have a
Munsell color notation of 7.5 YR 5/6. Hydrological indicators include damp soil, the
presence of oxidized rhizospheres and water stained leaves. Vegetation within the
wetlands include: rush, false nettle, sedge, Japanese grass, goldenrod, beggar ticks,
dayflower, woolgrass, and smartweed.
Perr y Creek is a jurisdictional surface water under Section 404 of the Clean Water
Act (33 U.S.C. 1344). Discussion of the biological, physical and water quality aspects of
Perry Creek are presented in previous sections of this report.
Summary of Anticipated Impacts
Anticipated impacts to wetland areas are determined by using the entire project
ROW width of 120.0 ft (36.6 m). Total impacts to wetlands have been determined to be
0.26 acre (0.11 ha) for Alternate 1, as well as Alternate 2. Impacts to Perry Creek have
been determined to be 120.0 ft (36.6 m) due to Alternate 1, as well as Alternate 2.
Usually, project construction does not require the entire ROW, therefore, actual wetlands
and surface water impacts may be considerably less.
Permits
impacts to jurisdictional surface waters are anticipated. In accordance with
provisions of section 404 of the Clean Water Act (33 U.S.C. 1344), a permit will be
required from the COE for the discharge of dredged or fill material into "Waters of the
United States."
A Section 404 Nationwide Permit 33 CFR 330.5(a) (23) is likely to be applicable
for all impacts to Waters of the United States from the proposed project. This permit
authorizes activities undertaken, assisted, authorized, regulated, funded or financed in
whole, or part, by another Federal agency or department where that agency or department
has determined that pursuant to the council on environmental quality regulation for
implementing the procedural provisions of the National Environmental Policy Act;
(1) that the activity, work, or discharge is categorically excluded from environmental
documentation because it is included within a category of actions which neither
individually nor cumulatively have a significant effect on the human environment,
and;
(2) that the office of the Chief of Engineers has been furnished notice of the agency' or
department's application for the categorical exclusion and concurs with that
determination.
A North Carolina Division of Water Quality (DWQ) Section 401 Water Quality
15
General Certification is required prior to the issuance of the Section 404 Nation"vide
Permit No. 23. Section 401 Certification allows surface waters to be temporarily
impacted for the duration of the construction or other land manipulations.
Neuse River Buffers
As the project is located in the Neuse River Basin, Riparian Area Rules for
Nutrient Sensitive Waters apply. The rules state that roads, bridges, stormwater
management facilities, ponds, and utilities may be allowed where no practical alternative
exists. They also state that these structures shall be located, designed, constructed, and
maintained to have minimal disturbance, to provide maximum erosion protection, to have
the least adverse effects on aquatic life and habitat, and to protect water quality to the
maximum extent practical through the use of best management practices. Every
reasonable effort will be made to avoid and minimize wetland and stream impacts.
Estimated impacts to the riparian buffers are quantified in Table 5. It is possible
the water resource listed below may be exempted when an on-site determination by the
Division of Water Quality is conducted. Therefore impacts may be considerably less.

Mitigation
DP- Depressional Wetland
MR- Maintained Roadside/ Residential
The COE has adopted, through the Council on Environmental Quality (CEQ), a'
wetland mitigation policy which-embraces the concept of "no net loss of wetlands" and
sequencing. The purpose of this policy is to restore and maintain the chemical, biological
and physical integrity of Waters of the United States, specifically wetlands. Mitigation of
wetland impacts has been defined by the CEQ to include: avoiding impacts (to wetlands),
minimizing impacts, rectifying impacts, reducing impacts over time and compensating
for impacts (40 CFR 1508.20). Each of these three aspects (avoidance, minimization and
compensatory mitigation) must be considered sequentially.
Avoidance
Avoidance mitigation examines all appropriate and practicable possibilities of
averting impacts to Waters of the United States. According to a 1990 Memorandum of
Agreement (MOA) between the Environmental Protection Agency (EPA) and the COE,
in determining "appropriate and practicable" measures to offset unavoidable impacts,
such measures should be appropriate to the scope and degree of those impacts and
practicable in terms of cost, existing technology and logistics in light of overall project
purposes. Wetland impacts can be avoided by confining construction activities within the
boundaries of the existing road shoulder (maintained/disturbed community).
Minimization
Minimization includes the examination of appropriate and practicable steps to
reduce the adverse impacts to Waters of the United States. Implementation of these steps
will be required through project modifications and permit conditions. Minimization
typically focuses on decreasing the footprint of the proposed project through the
16
reduction of median widths. ROW widths. fill slopes and/or road shoulder widths. Other
practical mechanisms to minimize impacts to Waters of the United States crossed by the
proposed project include: strict enforcement of sedimentation control BMP's for the
protection of surface waters during the entire life of the project- -reduction of clearing and
grubbing activity; reduction/elimination of direct discharge into streams; reduction of
runoff velocity; re-establishment of vegetation on exposed areas, judicious pesticide and
herbicide usage; minimization of "in-stream" activity; and litter/debris control.
Compensatory Mitigation
Compensatory mitigation is not normally considered until anticipated impacts to
Waters of the United States have been avoided and minimized to the maximum extent
possible. It is recognized that "no net loss of wetlands" functions and values may not be
achieved in each and every permit action. Appropriate and practicable compensatory
mitigation is required for unavoidable adverse impacts, which remain after all appropriate
and practicable minimization has been required. Compensatory actions often include
restoration, creation and enhancement of Waters of the United States. Such actions should
be undertaken in areas adjacent to or contiguous to the discharge site. Compensatory
mitigation is not usually necessary with a Nationwide Permit No. 23, however the final
decision lies with the COE.
Bridge Demolition
Bridge No. 124 has four spans totaling 70.0 ft (21.3 m) in length. The deck and
bridge railings are composed of concrete. The substructure is composed of timber. Both
the bridge railings and substructure will be removed without dropping components into
Waters of the U.S. There is potential for components of the deck to be dropped into.
Waters of the U.S. The resulting temporary fill associated with the concrete deck is
approximately 33 cubic yards.
RARE AND PROTECTED SPECIES
Some populations of fauna and flora have been in, or are in, the process of decline
either due to natural forces or their inability to coexist with human activities. Federal law
(under the provisions of the Endangered Species Act of 1973, as amended requires that
any action, likely to adversely affect a species classified as federally-protected, be subject
to review by the U.S. Fish and Wildlife (FWS). Other species may receive additional
protection under separate state laws.
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
March 2000, the FWS lists the following federally protected species for Wake County
(Table 6). A brief description of each species' characteristics and habitat follows.

Scientific Name Common Name Status
Haliaeetus leucoce halus Bald eagle Threatened
Picoides borealis Red-cockaded woodpecker Endangered
Alasmidonta heterodon Dwarf wedge mussel Endanaered
Rhus michauxii Michaux's sumac Endangered
Threatened species are species that are likely to become endangered within the foreseeable future
throughout all or a significant portion of its range. Endangered is defined as a species that is threatened
with extinction throughout all or a significant portion of its range.
Haliaeetus leucocephalus (bald eagle) Threatened
Family: Accipitridae
Date Listed: March 11, 1967
Adult bald eagles can be identified by their large white head and short white tail.
The body plumage is dark-brown to chocolate-brown in color. In flight bald eagles can
be identified by their flat wing soar.
Eagle nests are found in proximity to water (within a half mile) with a clear flight
path to the. water, in the largest living tree in an area, and having an open view of the
surrounding land. Human disturbance can cause an eagle to abandon otherwise suitable
habitat. The breeding season for the bald eagle begins in December or January. Fish are
the major food source for bald eagles. Other sources include coots, herons, and wounded
ducks. Food may be live or carrion.
BIOLOGICAL CONCLUSION NO EFFECT
Suitable nesting habitat in the form of large trees with a clear flight path to water .
is not present within the project vicinity. The trees occupying the canopy of the alluvial
forest are fairly uniform in height and the trees in the mixed pine hardwood forest are
uniform in height and very dense. Open water that is of sufficient size for foraging
opportunities for the bald eagle (Falls Lake) is approximately 5.3 mi (8.5 km) northeast
of the project area. A review of the NC Natural Heritage Program (NCNHP) database of
rare species and unique habitats, on November 18, 1999, has no record for the presence of
the bald eagle within the project vicinity. Therefore, project construction will not affect
the bald eagle.
Picoides borealis (red-cockaded woodpecker) Endangered
Family: Picidae
Federally Listed: October 13, 1970
The red-cockaded woodpecker (RCW) once occurred from New Jersey to
southern Florida and west to eastern Texas. It occurred inland in Kentucky, Tennessee,
Arkansas, Oklahoma, and Missouri. The RCW is now found only in coastal states of its
historic range and inland in southeastern Oklahoma and southern Arkansas. In North
Carolina moderate populations occur in the sandhills and southern coastal plain. The few
populations found in the piedmont and northern coastal plain are believed to be relics of
former populations.
The adult red-cockaded woodpecker (RCW) has a plumage that is entirely black
and white except for small red streaks on the sides of the nape in the male. The back of
the RCW is black and white with horizontal stripes. The breast and underside of this
18
woodpecker are white with streaked flanks. The RCW has a large white cheek patch
surrounded by the black cap. nape, and throat.
The RCW uses open old growth stands of southern pines. particularly longleaf
pine (Pinus palustris), for foraging and nesting habitat. A forested stand must contain at
least 50% pine, lack a thick understory, and be contiguous with other stands to be
appropriate habitat for the RCW. These birds nest exclusively in trees that are >60 years
old and are contiguous with pine stands at least 30 years of age. The foraging range of
the RCW is up to 500 acres (200 hectares). This acreage must be contiguous with
suitable nesting sites.
These woodpeckers nest exclusively in living pine trees and usually in trees that
are infected with the fungus that causes red-heart disease. Cavities are located in colonies
from 12-100 ft (3.6-30.3 m) above the ground and average 30-50 ft (9.1-15.7 m) high.
They can be identified by a large incrustation of running sap that surrounds the tree. The
large incrustation of sap is believed to be used as a defense by the RCW against possible
predators. A clan of woodpeckers usually consists of one breeding pair and the offspring
from previous years. The RCW lays its eggs in April, May, and June and hatch 38 days
later. Clutch size ranges in number from 3-5 eggs. All members of the clan share in
raising the young. Red-cockaded woodpeckers feed mainly on insects but may feed on
seasonal wild fruits.
BIOLOGICAL CONCLUSION NO EFFECT
Suitable nesting habitat in the form of large pine trees with little understory is not
present within the project vicinity. The mixed pine hardwood forest present is primarily
comprised of hardwoods and has a dense understory. A review of the NCNHP database
of rare species and unique habitats, on November 18, 1999, has no record for the presence
of red-cockaded woodpecker within the project vicinity. Therefore, project construction
will not affect the red-cockaded woodpecker.
Alasmidonta heterodon (dwarf wedge mussel) Endangered
Animal Family: Unionidae
Dat'Listed: March 14, 1990
Alasmidonta heterodon formerly ranged from the Petitcodiac River, Canada to the
Neuse River, North Carolina. In North Carolina populations are found in Middle Creek
and the Little River of the Neuse River Basin and in the upper Tar River and Cedar,
Crooked, and Stony Creeks of the Tar River system. .
The dwarf wedge mussel is a small mussel ranging in size from 2.5 cm to 3.8 cm
in length. Its shell is distinguishable by two lateral teeth on the right half and one on the
left half. The periostracum (outer shell) is olive green to dark brown in color and the
nacre (inner shell) is bluish to silvery white.
Successful reproduction is dependent on the attachment of larval mussels to a host
fish. It is not known what the host fish is but evidence suggests that it is either an
anadromous or catadromous species. This mussel is sensitive to agricultural, domestic,
and industrial pollutants and requires a stable silt free streambed with well oxygenated
water to survive.
BIOLOGICAL CONCLUSION NO EFFECT
19
On July 27. 1999. NCDOT biologists Lynn Smith and Sue Brady surveyed Perri
Creek within the project study area. Suitable habitat for dwarf wedge mussel is not
present within this portion of Perry Creek. The survey was conducted by wading through
the stream and utilizing visual techniques. Two Elliptio spp. were found utilizing one
man hour of search time. A review of the NCNHP database on November 18, 1999
indicated that there are no known occurrences of dwarf wedge mussel within the project
study area. Therefore, this project will not affect dwarf wedge mussel.
Rhus michauxii (Michaux's sumac) Endangered
Family: Anacardiaceae
Federally Listed: September 28, 1989
Flowers Present: June
Michaux's sumac is a densely pubescent rhizomatous shrub. The bases of the
leaves are rounded and their edges are simply or doubly serrate. The flowers of
Michaux's sumac are greenish to white in color. Fruits, which develop from August to
September on female plants, are a red densely short-pubescent drupe.
This plant occurs in rocky or sandy open woods. Michaux's sumac is dependent
on some sort of disturbance to maintain the openness of its habitat. It usually grows in
association with basic soils and occurs on sand or sandy loams. Michaux's sumac grows
only in open habitat where it can get full sunlight. Michaux's sumac does not compete
well with other species, such as Japanese honeysuckle, with which it is often associated.
BIOLOGICAL CONCLUSION NO EFFECT
Potential habitat for Michaux's sumac is present only within the road shoulder
portions of the project area. A plant by plant survey for Michaux's sumac, within areas
of potential habitat was conducted on July 1, 1999 by NCDOT biologists Bruce O. Ellis
and Lynn Smith. No Michaux's sumac was observed during the survey. A review of the
NCNHP database of rare species and unique habitats, on November 18, 1999, contains
one record of Michaux's sumac within the project region. A population of Michaux's
sumac is located approximately 1.5 mi (2.4 km) southwest of Bridge No. 124. However,
replacement of Bridge No. 124 will not affect this plant population. Therefore, project
construction will not affect Michaux's sumac.
Federal Species of Concern and State Listed Species
There are eleven Federal Species of Concern (FSC) listed for Wake County.
Federal Species of Concern are not afforded federal protection under the ESA and are not
subject to any of its provisions, including Section 7, until they are formally proposed or
listed as Threatened or Endangered. Federal Species of Concern are defined as those
species, which may or may not be listed in the future. These species were formally
candidate species, or species under consideration for listing for which there was
insufficient information to support a listing of Endangered, Threatened, Proposed
Endangered and Proposed Threatened. Organisms which are listed as Endangered (E),
Threatened (T), Significantly Rare (SR) or Special Concern (SC) by the North Carolina
Natural Heritage Program (NCNHP) list of rare plant and animal species are afforded
state protection under the State Endangered Species Act and the North Carolina Plant
Protection and Conservation Act of 1979.
20
Table 7 lists Federal Candidate and State listed species. the species state status
and the existence of suitable habitat for each species in the study area. This species list is

"SC"--- A Special Concern species is one which requires monitoring but which may be taken under
regulations adopted under the provisions of Article 25 of Chapter 113 of the General Statutes.
"SR"---- A Significantly Rare species is one which has not been listed by the N.C. Wildlife Resources
Commission as an Endangered, Threatened, or Special Concern species, but which exists in the state in
small numbers and has been determined by the N.C. Natural Heritage Program to need monitoring.
"(PSC), (PE)"-Species has been proposed by a Scientific Council as a status that is different from the
current status, but the status has not yet been adopted by the WRC and by the General Assembly as law.
Surveys for these species were not conducted during the site visit, nor were any of
these species observed. A review of the NCNHP database of rare species and unique
habitats on November 18, 1999 revealed no records of North Carolina rare and/or
protected species in or near the project study area.

Biologists with the N. C. Wildlife Resources Commission (NCWRC) have
reviewed the information provided and have the following preliminary comments on the
subject project. Our comments are provided in accordance with 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).
On bridge replacement projects of this scope our standard recommendations are as
follows:
1. We generally prefer spanning structures. Spanning structures usually do not
require work within the stream and do not require stream channel realignment.
The horizontal and vertical clearances provided by bridges allows for human
and wildlife passage beneath the structure, does not block fish passage, and
does not block navigation by canoeists and boaters.
2. Bridge deck drains should not discharge directly into the stream.
3. Live concrete should not be allowed to contact the water in or entering into the
stream.
4. If possible, bridge supports (bents) should not be placed in the stream.
Bridge Replacement Memo 2 March 19, 1999
5. If temporary access roads or detours are constructed, they should be removed
back to original ground elevations immediately upon the completion of the
project. Disturbed areas should be seeded or mulched to stabilize the soil and
native tree species should be planted with a spacing of not more than 10'x10'.
If possible, when using temporary structures the area should be cleared but not
grubbed. Clearing the area with chain saws, mowers, bush-hogs, or other
mechanized equipment and leaving the stumps and root mat intact, allows the'
area to revegetate naturally and minimizes disturbed soil.
6. A clear bank (riprap free) area of at least 10 feet should remain on each side of
the steam underneath the bridge.
7. In trout waters, the N.C. Wildlife Resources Commission reviews all U.S.
Army Corps of Engineers nationwide and general `404' permits. We have the
option of requesting additional measures to protect trout and trout habitat and
we can recommend that the project require an individual `404' permit.
8. In streams that contain threatened or endangered species, NCDOT biologist
Mr. Tim Savidge should be notified. Special measures to protect these
sensitive species may be required. NCDOT should also contact the U.S. Fish
and Wildlife Service for information on requirements of the Endangered
Species Act as it relates to the project.
9. In streams that are used by anadromous fish, the NCDOT official policy
entitled "Stream Crossing Guidelines for Anadromous Fish Passage (May 12,
1997)" should be followed.
10. In areas with significant fisheries for sunfish, seasonal exclusions may also be
recommended.
If corrugated metal pipe arches or concrete box culverts are used:
1. The culvert must be designed to allow for fish passage. Generally, this means
that the culvert or pipe invert is buried at least I foot below the natural stream
bed. If multiple cells are required the second and/or third cells should be
placed so that their bottoms are at stream bankful stage (similar to Lyonsfield
design). This will allow sufficient water depth in the culvert or pipe during
normal flows to accommodate fish movements. If culverts are long, baffle
systems are required to trap gravel and provide resting areas for fish and other
aquatic organisms.
2. If multiple pipes or cells are used, at least one pipe or box should be designed
to remain dry during normal flows to allow for wildlife passage.
3. Culverts or pipes should be situated so that no channel realignment or
widening is required. Widening of the stream channel at the inlet or outlet of
structures usually causes a decrease in water velocity causing sediment
deposition that will require future maintenance.
4. Riprap should not be placed on the stream bed.
In most cases, we prefer the replacement of the existing structure at the same
location with road closure. If road closure is not .feasible, a temporary detour should be
designed and located to avoid wetland impacts, minimize the need for clearing and to
Bridge Replacement Memo
March 19, 1999
avoid destabilizing stream banks. If the structure will be on anew alignment, the old
structure should be removed and the approach fills removed from the 100-year
floodplain. Approach fills should be removed down to the natural ground elevation. The
area should be stabilized with grass and planted with native tree species. If the area that
is reclaimed was previously wetlands, NCDOT should restore the area to wetlands. If
successful, the site may be used as wetland mitigation for the subject project or other
projects in the watershed.
Project specific comments:
1. B-3459 - Granville County - Bridge No. 6 is over Island Creek, which is low
gradient, deep channeled stream with a sand and silt substrate. This stream
may provide fair fishing for sunfish and pickerel. Our general comments
apply.
2. B-3481 - Johnston County - Bridge No. 94 is over the Little River. The
federally endangered dwarf wedgemussel (Alismidonta heterodon) and other
freshwater mussels are found just downstream of this bridge. We request that
a field meeting be held to discuss conservation measures to protect these
species. This structure should be replaced specifically with a bridge. There
are plans to remove a dam on the Little River downstream of this site which
will open this area up to anadromous fish runs.
3. B-3210 - Montgomery County - Bridge No. 45 over the Uwharrie River. The
Uwharrie River is a very high quality stream and supports an important and
diverse fishery for all sunfish and also supports a spawning run for white bass
from Lake Tillery. The river also contains numerous species of freshwater
mussels including federal species of concern as well as state listed species.
The Uwharrie and Little rivers are two of only a few river basins within the
Pee Dee system which still supports a high diversity of mussels. We request
that NCDOT hold a field meeting to discuss mussel conservation measures.
We request that sedimentation and erosion control measures for sensitive
watersheds be used to protect these aquatic resources. No in-water work
should be performed from March 1 to May 30. We request that the new
structure be replaced on existing location. If the bridge must be replaced on
new location, the old bridge approaches should be retained and used as a
fishing access area.
4. B-3529 - Wake County - Bridge No. 124 crosses Perry Creek a tributary to
the Neuse River. Due to recent dam removals on the Neuse River this stream
now supports an anadromous fish spawning run. Therefore, NCDOT should
follow the NCDOT officially adopted document " Stream Crossing Guidelines
for Anadromous Fish Passage". No in-water work should occur from
February 15 to June 15.
5. B-3534 - Watauga County - Although this project was sent to field biologists
for comment, I have not received comments at this time. There is the
possibility that you may.receive comments directly from the biologist or
through the U.S. Army Corps of Engineers.
We request that NCDOT routinely minimize adverse impacts to fish and wildlife
resources in the vicinity of bridge replacements. The NCDOT should install and
maintain sedimentation control measures throughout the life of the project and prevent
Bridge Replacement Memo 4 March 19, 1999
wet concrete from contacting water in or entering into these streams. Replacement of
bridges with spanning structures of some type, as opposed to pipe or box culverts, is
recommended in most cases. Spanning structures allow wildlife passage along
streambanks, reducing habitat fragmentation and vehicle related mortality at highway
crossings.
If you need further assistance or information on NCWRC concerns regarding
bridge replacements, please contact me at [phone]. Thank you for the opportunity
to review and comment on these projects.
