Subject: Nationwide 3 Notification and Buffer Authorization Request, for the demolition and
reconstruction of Bridge No.. 170, SR 1733 over the Little River, Johnston County. TIP
Project Number : B-4166
Dear Sirs:
Please find enclosed the Pre-Construction Notification for the above referenced project. The sufficiency
rating of this bridge is 17.8 out of 100. Although it had been scheduled for replacement in 2006, Bridge
No. 170 has failed requiring the closure of SR 1733. The existing bridge (80' long) will be replaced
with a new 140-foot long bridge (80-foot center span with 30-feet approach spans) on the existing
alignment. Traffic will continue to use the offsite detour during construction. There are impacts to
buffers and Waters of the U.S./State associated with this project. The new bridge will completely span
the creek and a much larger portion of floodplain. The bridge replacement will result in a better
hydraulic opening and provide for increased wildlife passage beneath the future bridge. The Little River
is located in the Neuse River Basin and is classified by the Division of Water Quality at this bridge as
WS-V:NSW 27-57-(8.5).
The bridge will be removed by sawing the deck and lifting it out in sections. We will excavate behind
the end bents and fold them back, then remove them without dropping any components into the creek.
Both wooden and steel piles from the existing bridge will be cut off at the mud line of the stream using a
hydraulic shear or other means that does not require construction equipment to get into the water. Best
Management Practices for the Protection of Surface Waters and for Bridge Demolition and Removal
will be strictly adhered to during the removal of the existing bridge.

FEDERALLY-PROTECTED SPECIES AND CULTURAL RESOURCES
The Fish and Wildlife Service (FWS) currently list four federally protected species for Johnston County
(Table 1).
Table 1- Federally Protected Species of Johnston County
Federal Habitat Biological
Common Name Scientific Name Status Present Conclusion
Red-cockaded Picoides borealis E N No Effect
woodpecker
Dwarf wedge mussel Alasmidonta heterodon E N No Effect
Tar spiny mussel Elliptio steinstansana E N No Effect
Michaux's sumac Rhus michauxii E N No Effect
A mussel survey was conducted at the project site on June 25, 2004. None of the federally listed species
were found, and habitat quality for the two mussel species was found not to be optimal. However it is
noted that the dwarf wedge mussel has historically been found 2-3 miles downstream and several miles
upstream. No element occurrences are listed on the NHP database within one mile of the bridge. No
pine trees suitable for RCW foraging or nesting are in, or adjacent to, the bridge. No suitable Michaux's
sumac habitat will be impacted. This project is not likely to jeopardize the continued existence of any
of the federally protected species listed in Johnston County. The Fish and Wildlife Service met with the
NCDOT onsite and provided the attached concurrence letter on November 5, 2004.
No sites eligible for listing on the National Register occur within the area of potential effect. This
project will not affect listed or eligible historic properties. The NCSHPO Environmental Review
Coordinator met with the NCDOT and provided the attached concurrence letter on February 21, 2001.
Regulatory Approvals
USACE Section 404 Permit: The project qualifies for Nationwide Permit 3 (Maintenance of previously
approved structures). All permit conditions will be followed. Impacts to 65 linear feet of Waters of the
U.S. may result from the placement of rip rap for stabilization. For our files, please provide general
permit verification that the activity is authorized.
NCDWQ Section 401 Certification: The project qualifies for 401 General Certification number 3376.
All conditions of the general certification will be followed.
NCDW , Buffer Rules: As bridges are an allowable use they require written authorization from the
Division of Water Quality. Only Buffer Rule approval is sought in writing.
Please give me a call or email if you have any questions.

local stormwater requirement, etc.): NA
Size of watershed draining to pond: NA Expected pond surface area: NA
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.
The bridge length will be extended from 80' to 140' to span a larger portion of the
floodplain There will be no new bents in the stream. Offsite detour avoids temporary fill
from onsite detour. Equipment staging and work will be performed within the existing
road footprint Strict enforcement of Best Management Practices for sedimentation and
erosion control the protection of wetlands and surface waters, and bridge demolition
will be enforced during project construction. Both wooden and steel piles from the
existing bridge will be cut off at the mud line of the stream using a hydraulic shear or
other means that does not require construction equipment to get into the water. No
temporary causeways or temporary work pads will be allowed in the stream during
construction No weep holes will be allowed in the bridge deck which allow water to
drain directly into the stream Special sediment control fence (hardware cloth and
stone) will be used where appropriate throughout all phases of construction.
VIII. 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.
Page 9 of 12
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
htip://h2o.enr.state.nc.us/ncwetlands/stnngide.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.
No further mitigation is proposed for this protect Bridges are an allowable use per
Buffer Rules.
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

Project Description:
B-4166
8.2312701
33514.1.1
BRZ-1733(12)
A NO
This project proposes to replace Bridge No. 170 on SR 1733 over the Little River
in Johnston County. The replacement structure will be an approximately 100-foot
long bridge. The bridge will be of sufficient width to provide for two 11-foot
lanes with at least three-foot offsets on each side. Traffic will be detoured offsite
during construction.
The roadway grade of the new structure will be approximately the same as the
existing grade at this location.

V`n
L

The approach roadway extending approximately 550 feet from the end of the
bridge on the east approach and 300 feet from the end of the bridge on the west
approach will be widened to a 22-foot pavement width to provide two 11-foot ` r
lanes. Four-foot grass shoulders will be provided on each side (seven-foot (? 1(
shoulders where guardrail is included). This roadway will be designed as a rural
local route with a 60 mile per hour design speed. v (,
Purpose and Need:
Bridge No. 170 includes a two-span superstructure composed of an asphalt-
wearing surface on a timber deck on steel girders. The substructure includes
timber caps on timber piles. Steel crutches have been added for temporary
support until the bridge can be replaced.
Bridge Maintenance Unit records indicate the bridge has a sufficiency rating of
17.8 out of a possible 100 for a new structure. The bridge is considered
structurally deficient due to a structure appraisal of 4 out of 9 according to
Federal Highway Administration (FHWA) standards and therefore eligible for
FHWA's Highway Bridge Replacement and Rehabilitation Program. Timber
structures typically do not last beyond 30 to 40 years of age due to the natural
deterioration rates of wood. Rehabilitation of a timber structure is generally
practical only when a few members are damaged or prematurely deteriorated.
However, past a certain degree of deterioration, timber structures become
impractical to maintain and upon eligibility are programmed for replacement.
C. Proposed Improvements:
Circle one or more of the following Type II improvements which apply to the
project:

1. Modernization of a highway by resurfacing, restoration, rehabilitation,
reconstruction, adding shoulders, or adding auxiliary lanes (e.g., parking,
weaving, turning, climbing).
a. Restoring, Resurfacing, Rehabilitating, and Reconstructing
pavement (3R and 4R improvements)
b. Widening roadway and shoulders without adding through lanes
c. Modernizing gore treatments
d. Constructing lane improvements (merge, auxiliary, and turn lanes)
e. Adding shoulder drains
f. Replacing and rehabilitating culverts, inlets, and drainage pipes,
including safety treatments
g. Providing driveway pipes
h. Performing minor bridge widening (less than one through lane)
L Slide Stabilization
J. Structural BMP's for water quality improvement
2. Highway safety or traffic operations improvement projects including the
installation of ramp metering control devices and lighting.
a. Installing ramp metering devices
b. Installing lights
c. Adding or upgrading guardrail
d. Installing safety barriers including Jersey type barriers and pier
protection
e. Installing or replacing impact attenuators
f. Upgrading medians including adding or upgrading median barriers
g. Improving intersections including relocation and/or realignment
h. Making minor roadway realignment
i. Channelizing traffic
j. Performing clear zone safety improvements including removing
hazards and flattening slopes
k. Implementing traffic aid systems, signals, and motorist aid
1. Installing bridge safety hardware including bridge rail retrofit
O Bridge rehabilitation, reconstruction, or replacement or the construction of
grade separation to replace existing at-grade railroad crossings.
a. Rehabilitating, reconstructing, or replacing bridge approach slabs
b. Rehabilitating or replacing bridge decks
c. Rehabilitating bridges including painting (no red lead paint), scour
repair, fender systems, and minor structural improvements
O Replacing a bridge (structure and/or fill)
4. Transportation corridor fringe parking facilities.
5. Construction of new truck weigh stations or rest areas.
6. Approvals for disposal of excess right-of-way or for joint or limited use of
right-of-way, where the proposed use does not have significant adverse
impacts.
7. Approvals for changes in access control.
8. Construction of new bus storage and maintenance facilities in areas used
predominantly for industrial or transportation purposes where such
construction is not inconsistent with existing zoning and located on or near
2
a street with adequate capacity to handle anticipated bus and support
vehicle traffic.
9. Rehabilitation or reconstruction of existing rail and bus buildings and
ancillary facilities where only minor amounts of additional land are
required and there is not a substantial increase in the number of users.
10. Construction of bus transfer facilities (an open area consisting of
passenger shelters, boarding areas, kiosks and related street
improvements) when located in a commercial area or other high activity
center in which there is adequate street capacity for projected bus traffic.
11. Construction of rail storage and maintenance facilities in areas used
predominantly for industrial or transportation purposes where such
construction is not inconsistent with existing zoning and where there is no
significant noise impact on the surrounding community.
12. Acquisition of land for hardship or protective purposes, advance land
acquisition loans under section 3(b) of the UMT Act. Hardship and
protective buying will be permitted only for a particular parcel or a limited
number of parcels. These types of land acquisition qualify for a CE only
where the acquisition will not limit the evaluation of alternatives,
including shifts in alignment for planned construction projects, which may
be required in the NEPA process. No project development on such land
may proceed until the NEPA process has been completed.
13. Acquisition and construction of wetland, stream and endangered species
mitigation sites.
14. Remedial activities involving the removal, treatment or monitoring of soil
or groundwater contamination pursuant to state or federal remediation
guidelines.
D. Special Project Information:
Estimated Costs:
Total Construction $ 625,000
Right of Way $ 30,000
Total $ 655,000
Estimated Traffic:
Current - 425
Year 2025 - 600
TTST - 1%
Dual - 2%
Accidents: In a check of a recent three-year period, no accidents were reported at this
site.
Design Speed: 60 mph
Functional Classification: Rural Local Route
3
School Busses: During the school year there are eighteen school bus crossings per day at
this location. The Transportation Director for Johnston County indicated that closing the
road for a short period of time would be acceptable.
Division Office Comments: The Division concurs with the proposed alternate.
Bridge Demolition: Bridge 170 is composed timber and steel piles with timber caps and
a timber and steel superstructure. It is likely that, using standard demolition techniques,
all components can be removed without any debris falling into the water.
Studied Offsite Detour: NCDOT Guidelines for Evaluation of Offsite Detours for
Bridge Replacement Projects considers multiple project variables beginning with the
additional time traveled by the average road user resulting from the offsite detour. The
studied offsite detour for this project would include NC 96, NC 42, NC 39 and back to
SR 1733. The detour for the average road user would result in 5.5 minutes additional
travel time (3.4 miles additional travel) which falls within the range of acceptable delay
for the four-month duration of construction expected on this project. Johnston County
Emergency Services and Johnston County School Transportation have indicated that an
offsite detour is acceptable and that services can be adequately re-routed during
construction. The Division concurs in this recommendation.
Note that after its August 2004 inspection a decision was made to close Bridge No. 170
to traffic until this project can be completed and the bridge can be replaced.
Design Exception: There will be a design exception required for horizontal design speed
due to the eastern approach alignment meeting only a 45 mph speed.

This letter is in response to your letter of November 1, 2004- which provided the U.S. Fish and
Wildlife Service (Service) with the biological determination of the North Carolina Department of
Transportation (NCDOT) that the replacement of Bridge No. 170 on SR 1733 over Little River
in Johnston County (TIP No. B-4166) may affect, but is not likely to adversely affect the
federally endangered dwarf wedgemussel (Alasmidonta heterodon) and Tar spinymussel
(Elliptio steinstansana). These comments are provided in accordance with section 7 of the
Endangered Species Act (ESA) of 1973, as amended (16 U.S.C. 1531-1543).
According to information previously provided, a mussel survey was conducted at the project site
on June 25, 2004. The survey extended 100 meters upstream and 400 meters downstream of SR
1733. Neither of the federally listed species was found, and habitat quality for the two species
was not optimal. However, the dwarf wedgemussel has historically been found 2-3 miles
downstream and several miles upstream.
During an informal on-site meeting held on October 5, 2004 between Mr. Gary Jordan (Service
biologist) and-Mr. Neil Medlin (NCDOT), several conservation measures were discussed and
agreed upon by both parties. The commitments are listed below:
• No temporary causeway in the stream during construction
• No temporary work pads in the stream during construction
• The bridge will be replaced in place with the use of off-site detour
• Use BMPs for bridge demolition
• No weep holes that allow water to drain directly into stream
• Use special sediment control fence (i.e. hardware cloth and stone) throughout all phases
of construction
• The wet width of the stream will be spanned, either with a 20-60-20 arrangement or a
single 80 foot span depending on what hydro recommends in their final report
• Both the wooden and steel pilings will be cut off at the mud line using a hydraulic sheer
or cutting torch or saw as appropriate without having to get equipment into the water
• Based on the preliminary hydraulic report, it appears that some fill will be removed at
each end to accommodate a wider bridge opening,
I 4 , 0
Based on the mussel survey results and the commltment to the conservation nlcasures listed
above, the Service concurs with your determination that the proposed bridge replacement may
affect, but is not likely to adversely affect the dwarf wedgemussel and Tar spinymussel. We
believe that the requirements of section 7(a)(2) of the ESA have been satisfied for these species.
We remind you that obligations under section 7 consultation must be reconsidered if (1) new
information reveals impacts of this identified action that may affect listed species or critical
habitat in a manner not previously considered in this review; (2) this action is subsequently
modified in a manner that was not considered in this review; or (3) a new species is listed or
critical habitat determined that may be affected by this identified action.
The Service appreciates the opportunity to review this project. If you have any questions
regarding our response, please contact Mr. Gary Jordan at [phone] (Ext. 32).
Sincerely,
John Ellis
Acting Ecological Services Supervisor

Re: Replacement of Bridge 170 on SR 1733 over Little River,
TIP No. B-4166."Johnston County. ER 01-7935
On December 5. 2000 April Montgomery of our staff met with North Carolina
Department of Transportation (NCDOT) staff for a meeting of the minds concerning the
above project. We reported our available information on historic architectural and
archaeological surveys and resources along with our recommendations. NCDOT
provided project area photographs and aerial photographs at the meeting.
Based upon our review of the photographs and the information discussed at the meeting,
we offer our preliminary comments regarding this project.
In terms of historic architectural resources we are aware of no historic structures located
within the area of potential effect. We recommend that no historic architectural survey
be conducted for this project.
There are no known archaeological sites within the proposed project area. Based on our
present knowledge of the area, it is unlikely that any archaeological resources which may
be eligible for inclusion in the National Register of Historic Places, will be affected by
the project construction. We, therefore, recommend that no archaeological investigation
be conducted in connection with this project.
Having provided this information, we look forward to the receipt of either a Categorical
Exclusion or Environmental Assessment, which indicates how NCDOT addressed our
comments.
