ATTN: Mr. Stephen Lane
NCDOT Coordinator
Dear Sir,
Subject: CAMA Major Development Permit Application for the proposed
replacement of Bridge No. 104 on NC 32 over Broad Creek in Beaufort
County. Federal Project No. BRSTP-32(2), State Project No 8.1151401,
T.I.P. No. B-4018. Debit $400.00 from WBS Element 33385.1.1.
Please find enclosed copies of the Categorical Exclusion (CE) Document, MP Forms,
landowner notification cards, permit drawings, and roadway plans for the above
referenced project proposed by the North Carolina Department of Transportation
(NCDOT). The NCDOT plans to replace Bridge No. 104 over Broad Creek on NC 32 in
Beaufort County. The existing 172-foot long bridge will be replaced with a 200-foot long
structure using top-down construction in the existing location. During construction,
traffic will be maintained by an off-site detour. No permanent impacts and 0.02 acre of
hand clearing and 0.01 acre of temporary impacts to jurisdictional wetlands are
anticipated. Impacts to riparian buffers total 4,962 ft2 Impacts to jurisdictional surface
waters are anticipated to be <0.001 acre.
Impacts to Waters of the United States
General Description: The project study area is located within sub-basin 03-03-07 of the
Tar-Pamlico River Basin. This area is part of USGS Hydrologic Unit 03020104 of the
Mid-Atlantic/Coastal Plain Ecoregion. The project study area contains two streams:
Broad Creek and an unnamed tributary to Broad Creek (UT1).
Broad Creek and UT1 are within a riverine system that is subject to wind tides. Both
have an unconsolidated benthos consisting of muddy sediments. A best usage
classification of SB NSW has been assigned to this section of Broad Creek. Broad Creek

is not designated as a North Carolina Natural or Scenic River, or as a National Wild and
Scenic River. Broad Creek is not listed on any section of the NCDWQ Section 303(d)
list. Broad Creek is not located within 1 mile nor does it flow into a stream with 303(d)
classification. In addition, no designated Outstanding Resource Waters (ORW), High
Quality Waters (HQW), Water Supply I (WS-1), or Water Supply II (WS-II) waters occur
within 1.0 miles of the project study area.
Broad Creek, UT1, and their adjacent wetlands are subject to jurisdictional consideration
under Section 404 of the Clean Water Act as "Waters of the United States" (33 CFR
section 328.3). Wetlands within the study site exhibit characteristics of a palustrine-
forested system with broad-leaved deciduous and needle-leaved evergreen vegetation. In
addition, these wetlands are seasonally inundated, tidally influenced, and therefore under
jurisdiction of the North Carolina Division of Coastal Management according to the
Coastal Area Management Act (CAMA).
Permanent Impacts: Proposed permanent impacts to surface waters due to in-stream piers
will be <0.001 acre. This project will result in no permanent impacts to jurisdictional
wetlands.
Hand Clearing: Hand clearing (0.02 acre) will be necessary for project construction.
Utility Impacts: The relocation of a water supply pipe will result in 0.01 acre of temporary
excavation in jurisdictional wetlands.
Avoidance and Minimization
NCDOT has avoided and minimized impacts to the fullest extent possible:
• Traffic will be maintained using an off-site detour during construction.
• The bridge will be built in-place using top-down construction and can therefore be
built without the need of a causeway or work pad.
• The bridge is being lengthened by 28 feet.
• There will be no deck drains over surface waters.
• Design Standards in Sensitive Watersheds will be strictly adhered to.
• The number of interior bents in the water is being reduced from eight for the existing
bridge to three for the new bridge.
Mitigation
The proposed project will have no permanent impacts to wetlands. Temporary impacts
totaling 0.01 acre are a result of excavation of a water pipe. Following construction, this
area will be graded to preconstruction elevation and revegetated. Hand clearing in the
vicinity of the north abutment (0.02 ac) is not a jurisdictional impact and therefore does
not require mitigation. Because there are no permanent impacts to jurisdictional
wetlands, and impacts to riparian buffers have not exceeded the threshold requiring
compensatory mitigation, NCDOT is not proposing mitigation.

Bridge Demolition
The existing bridge is 172 feet in length, consisting of ten spans with the maximum span
approximately 18 feet. The superstructure consists of a reinforced concrete floor on
timber joists. The substructure consists of timber caps on timber piles. The bed to crown
height is 19.7 feet and the normal depth of flow is 11 feet. The bridge will be removed
using Best Management Practices (BMP's) for Bridge Demolition to avoid any temporary
fill in "Waters of the United States".
Bridge Construction
Bridge No. 104 will be replaced with a 200-foot long, 4-span structure in the existing
location. A single-row driven-pile substructure will support a cored slab superstructure.
Construction of this bridge will not require a temporary causeway.
Federally-Protected Species
Plants and animals with federal classifications of Endangered, Threatened, Proposed
Endangered, and Proposed Threatened are protected under Endangered Species Act §§7
and 9. As of January 29, 2007, the US Fish and Wildlife Service (USFWS) lists 7
federally protected species for Beaufort County (Table 1).
Biological conclusions of "No Effect" were reached for Kemp's ridley sea turtle, Red-
cockaded woodpecker (Picoides borealis), rough-leaved loosestrife (Lysimachia
asperulaefolia), and sensitive jointvetch (Aeschynomene virginica). A biological
conclusion of "May Affect, Not Likely to Adversely Affect" was reached for Bald Eagle
(Haliaeetus leucocephalus) and West Indian manatee (Trichechus manatus). Concurrence
from the USFWS was received for all species on May 5, 2006. A copy of this letter is
included with this application.
Due to the presence of potential West Indian Manatee habitat, NCDOT has committed to
implementing Guidelines for Avoiding Impacts to the West Indian Manatee:
Precautionary Measures for Construction Activities in North Carolina Waters.

In-Stream Work Moratorium
As required by the NC Wildlife Resources Commission (NCWRC), a moratorium on in-
stream construction activities will be strictly adhered for the dates between and including
February 15th and September 30th in order to protect striped bass (Morone saxatilis),
American shad (Alosa sapidissima), river herring (Alosa pseudoharengus), and hickory
shad (Alosa mediocris); all anadromous fish species. In addition, the Stream Crossing
Guidelines for Anadromous Fish Passage will be implemented.
Project Schedule
This project is scheduled to let December 18, 2007, with a review date of October 30,
2007.
Regulatory Approvals
CAMA Permit: The NCDOT hereby requests that this project be authorized by the
issuance of a Coastal Area Management Act Major Development Permit. Please find
attached the completed MP forms along with the appropriate permit drawings. The
certified mail "green cards" from the adjacent riparian landowner notifications are also
included.
Section 404 Permit: In a separate application, NCDOT is applying for a Clean Water Act
Section 404 General Permit. All aspects of this project are being processed by the Federal
Highway Administration as a "Categorical Exclusion". The NCDOT is requesting that
these activities be authorized by a General Permit No. 198200031.
Section 401 Permit: In a separate application, NCDOT is applying for a 401 Water
Quality Certification from DWQ. We anticipate 401 General Certification number 3404
will apply to this project. All general conditions of the Water Quality Certifications will
be met. Therefore, in accordance with 15A NCAC 2H, Section .0500(a), we are providing
five copies of this application to the NCDWQ for their review and written concurrence.
A copy of this permit application will be posted on the DOT website at:
http://www.ncdot.org/preconstruct/pe/neu/permit.html.
