Subject: NWP 3 PCN for Bridge No. 213 on SR 1710 (Emmet Thorton Road) over Kill Swamp in
Sampson County, WBS No. 17BP.3.PE.66

USACE Action ID No. SAW-2017-01255
DWR Project No. 20190695

Dear Mr. Shaver:

The North Carolina Department of Transportation (NCDOT) is preparing to replace the subject
bridge. It was anticipated that this project could be performed with authorization under NWP 3
with no written authorization required. You received a courtesy notification and confirmed the
applicability of NWP 3 for this project via e-mail on June 3, 2019. However, due to the recent
listing of wood stork in Sampson County by the U.S. Fish and Wildlife Service (USFWS), the
MANLAA concurrence by the USFWS (attached) now requires the Department to obtain written
approval.

As noted in the original courtesy notification letter, a preliminary jurisdictional determination (PJD)
was acquired on this project on June 28, 2017 and the project was assigned Action Id No. SAW-
2017-01255. Impacts associated with the bridge include 0.005 acres of (beneficial) wetland
excavation to tie the approach fill removal to the adjacent natural wetland floodplain elevation. The
only utility relocation associated with this project is a Centurylink fiber optic line, however there
are no impacts associate with this utility relocation. The attached permit drawings and utility plans
provide more details on the proposed impacts and are the same permit drawings and impacts that
were in the original courtesy notification. Traffic will use an offsite detour during the construction
of this project.

Required Regulatory approvals:

Section 404 (USACE) permit: NCDOT request written approval for NWP 3 as required for
the described activities above.

Section 401 (DWR) permit: Written approval for these activities is not required from N.C.
Division of Water Resources. The conditions of WQC 4132 will be included in the permit
packet for the contract and adhered to during construction.

We would appreciate your timely assistance with this request. If you have any questions or
need any additional information, please contact me at [e-mail] or 910-604-
0050.

Sincerely,

Dear Mr. Herndon:

This letter is in response to your letter of November 6, 2020 which provided the U.S. Fish and
Wildlife Service (Service) with the biological conclusion of the North Carolina Department of
Transportation that the replacement of Bridge No. 45 on SR 1162 over Island Creek in Duplin
County (STIP No. B-5303) and Bridge No. 213 on SR 1710 over Kill Swamp in Sampson
County may affect, but are not likely to adversely affect the federally threatened wood stork
(Mycteria americana). The following response is provided in accordance with Section 7 of the
Endangered Species Act (ESA) of 1973, as amended (16 U.S.C. 1531-1543).

Currently, there are no records of wood storks occurring in the vicinity of the projects. It is
understood that the projects will let in February 2021, thus they will be well underway prior to
the wood stork nesting season of April 15 – July 15. Wood storks are very uncommon in
Sampson and Duplin Counties and even less so prior to breeding season. Given the low
probability of the species occurring at the locations and the limited scope of the action, the
Service concurs with your conclusion that the proposed actions may affect, but are not likely to
adversely the wood stork.

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,

Pete Benjamin
Field Supervisor

The existing bridge consists of 1 @ 18' - 8", 1 @ 17' - 5", and 1 @ 17' - 4" Reinforced Concrete Deck on Timber Joists and Timber Piles and is to be replaced with a 1 @ 35' - 0" 21" Cored Slab, 1 @ 55'-0" 24" Cored Slab, Bridge (90' total length, 33' total width) at the same location. The proposed bridge does not contain deck drains. Storm water from the bridge and approaches will be collected by a storm drain inlets on the left and right side of the road and discharge into Class "I" Rip-Rap pads located in the northwest quadrant at -L- 17+94 LT and the northeast quadrant at -L- 18+17 RT. The existing roadside ditch in the southeast quadrant will be impacted by the proposed slope stakes. The proposed ditch will continue to flow from south to north and outlet into wetlands, matching existing drainage patterns. The proposed ditch in the southeast quadrant will be a Special Lateral base ditch with a 4' base and 3:1 front and back slopes. The ditch will transition into a '0' depth base ditch to reduce velocity and minimize impacts on wetlands.2 - 10' paved lanes with grass shoulders with roadside ditches.18-68-1-20.30.12Project DescriptionProposed ProjectCape Fear4202 - 10' asphalt paved lanes with 2' paved shoulders, 4' grass shoulders, and roadside dicth.
