Memorandum
To: John Parker
From: Haskell S. Rhett 104(/(:2
Subject: Consistency Opinion/NC DOT--Bridge #1 (Spring Branch) ,
Bridge #2 (Smith Creek)/New Hanover County
Date: May 26, 1992
Thank you for this opportunity to review the major permit
application named above. My opinion on consistency is based on my
review of the permit application, the field investigation report,
and my understanding and interpretation of policies presented in
the Wilmington-New Hanover County Land Use Plan Update.
The plan classification category for Spring Branch and Smith
Creek is Conservation. The reason given for including the land
adjacent to the creeks within in this category is that they are in
the 100-year floodplain. The threat of flood makes these areas
less suitable for intense development activity. Bridges are not
generally thought to be inconsistent with the Conservation
classification. {The overwhelming weight given in the plan to
resources protection, and the general need to consider health,
safety, and the public welfare, might, in some cases, cause public
facilities (including roads and bridges) to be inconsistent. )
Plan policy promotes highway improvements. The public trust
AEC, however, should be protected from development which will
significantly damage or alter the natural function of these areas.
The amount of wetlands fill seems significant. Mitigation plans
seem a reasonable means by which to ameliorate the consequences.
North Kerr Avenue is a major north-south highway in New
Hanover County. Traffic volume in 1985 was reported in the Land
Use Plan to reach as high as 17 ,700 vehicles per day on certain
portions of the road. Daily traffic counts can only have increased
within the last 7 years. Threat of flood from major storm events
should be an important consideration for this project.
The project seems consistent with the Wilmington-New Hanover
County Land Use Plan Update adopted by the Coastal Resources
Commission in January, 1987 .

Dear Mr. O'Quinn:
The Division of rnastal Management hereby acknowledges receipt of your
application for state approval for the replacement of Bridge 1 and Bridge 2 on North
Kerr Avenue (SR 1175) , New Hanover County. It was received in this office on January
29, 1992. The document was inadvertently misplaced and consequently the review has
been postponed until this time. The final date for action will be June 26, 1992. As
you are aware the Colps of Engineers has determined this action to be a categoric-al
exclusion. Our Raleigh office was notified of the delay and requested to notify you
of the necessary extension. I have been in recent telephone communication with Gordon
C .shin to inform him of the unfortunate circa stance of the lost application.
NCGS 113A-119(b) requires that Notice of an application be posted at the location
of the proposed development. Enclosed you will find a "Notice of Permit Filing"
postcard which must be posted at the site of your proposed project. You should post
this card at a conspicuous point along your property where it can be observed fLum a
public road. Same examples would be: nailing the notice card to a telephone pole or
tree along the road right-of-way fronting your property, or at a point along the road
right-of-way where a private road would lead one into your property. Failure to post
this Notice could result in an incomplete application.
A field report has been prepared and is in the process of being circulated to the
various state and federal review agencies for their comments. If additional
information is required based on this review, the agencies may contact you directly.
Please contact me if you have any questions and notify me in writing if you wish
to receive a copy of my field report and/or comments fruiu reviewing agencies.
Sincerely,
C. Robert Stroud, Jr.

9. PROJECT DESCRIPTION
The project sites consist of the two existing bridge crossings on
S.R. 1175 over two streams off the N.E. Cape Fear River. Site
one (1) is identified as the Spring Branch crossing. Site two (2)
is identified as the Smith Creek Crossing. Spring Branch is a
tidal stream and is a tributary of Smith Creek. It is
approximately 20 ' wide at this segment of the stream. The
existing bridge is approximately 40 ' long x 26 ' wide. The travel
way in this area is approximately 24 ' wide. The approaches on
either side are approximately 45 ' wide. Spring Branch is
classified as C SW and is considered to be Inland waters. The
wetlands associated with Spring Branch are of the freshwater
variety. Cypress, Pine, Black Gum, Green Ash and Alder are
present along the downstream area along with herbaceous emergent
species. On the upstream side of the road and bridge are found
Black Gum, Tulip Poplar, Red Maple, Bald Cypress, Water Oak,and
Pine. Smith Creek is a larger stream located approximately 1/4
mile north of Spring Branch. The creek is approximately 65 'wide
downstream of the existing bridge and approximately 40 ' wide
under the existing bridge. This structure is approximately 80 '
long x 24 ' wide. The existing road bed is approximately 45 ' to
50 ' wide at the approaches. Smith Creek is also classified as C
SW and is designated as Inland waters. The wetlands associated
with the upstream side of Smith Creek are Green Ash, Black Gum,
Bald Cypress, Alder, Red Maple, Water Oak and Tulip Poplar. There
are also unidentified emergent herbaceous species present. These
include two small colonies of narrow leafed cat-tail. There is
the distinct possibility that anadramous fish use both steams
during certain flow periods.
The applicants propose to remove the existing bridge at site 1
and replace it with a new structure comprised of three (3) 30 '
structures each 40 ' wide. In order to complete the work it will
be necessary to construct a temporary detour. This detour will
be placed over the existing channel of Spring Branch. The length
of this feature will be approximately 390 ' and the maximum width
will be approximately 60 ' . The natural channel will be directed
to a created channel approximately 120' long x 20 ' wide (top
width) . This flow in this feature will be conveyed under the
detour through 2 - 84" CSP to empty into the natural stream bed.
The natural channel turns sharply to the south just east of the
existing bridge and road bed. It follows down the bank of the
existing fill approach for approximately 210 ' . This alignment
threatens the existing bank. The applicants propose to reshape
the bank creating a 10 ' shelf and relocate this channel to a 10 '
bottom width. This work will occur approximately 25 ' east of the
existing toe of bank. On the southern approach, on the
downstream side the banks will be filled for an additional 120 '
approximately 5 ' into the wetlands. On the north approach the

Bridge #1 Spring Branch
Bridge #2 Smith Creek

9. PROJECT DESCRIPTION - Continued:
downstream side will have approximately 500 ' of 8 ' wide fill
placed into the wetlands. The upstream side will have
approximately 463 ' of 8 ' wide fill. The difference in the length
of fill on this side is a result of the presence of 2 existing
driveways. Approximately 165 ' of 8 ' to 10 ' wide class "I" rip
rap will be used to stabilize the new bridge approaches. The
area under the detour and temporary channel will be restored upon
completion of this phase of the project.
At site 2 the applicants are proposing to replace the existing
bridge within a new alignment in order to remove the existing
dangerous curve associated with the existing structure. The
structure will consist of three (3) - 42 ' bride spans each 40 '
wide. The southern approach will originate from high ground.
The northern approach will be created partially by the placement
of fill in wetlands. Approximately 360 ' of fill varying in width
from 0 ' to 90 ' will be constructed on the downstream side of
existing road bed. Approximately 230 ' of fill, up to 15 ' wide
will be used in the upstream side wetlands. The total roadbed
feature will average approximately 80 ' wide. The existing creek
will be widened under the bridge site approximately 20 ' for a
distance of approximately 120 ' in order to improve flow dynamics.
Approximately 160 ' of Class "I" rip-rap varying in width from 10 '
to 40 ' will be utilized to stabilize the banks of the approaches
adjacent to the bridge sites. Approximately 50 ' linear feet 15 '
side will be used in a curve of the bank downstream to prevent
the scour of the new approach fill in that location.
Approximately 280 ' of existing road bed averaging 30 ' wide will
be removed to existing adjacent wetland elevation.
10. ANTICIPATED IMPACTS
Smith Creek represents a very real threat to public safety with
the existing road alignment and poor existing bridge design.
Spring Branch requires upgrading also. Approximately 0.7 acres
of freshwater wetlands will be consumed by the proposed action at
both sites. The Spring Branch bridge will involve a permanent
loss of 0. 3 acres and the Smith Creek site will result in a net
loss of 0. 2 acres even though the initial impact will involve 0.4
acres due to the necessary re-alignment in order to ensure a safe
roadway. The proposed restoration at the Smith Creek site will
result in approximately 0. 2 acres of wetlands. Based on the 2 : 1
mitigation formula this 0. 2 acres will account for only 0. 1 acres
of the 0. 7 acres. The other 0. 6 acres will be accounted for
utilizing the Company Swamp Mitigation Bank. Based on current
agreements all impacts less that 5 acres will be debited from the
gum\cypress habitat credits remaining in the Company Swamp Bank.
The applicants are also proposing restoration guidelines
including the planting of hardwoods. (copy enclosed)

10. ANTICIPATED IMPACTS - Continued:
This project as proposed (especially the Smith Creek portion)
appears to have overriding public benefits which compensate for
the wetland losses. The Corps (see attached letter) has
designated this project as a categorical exclusion and has
authorized the action.
