Subject: Request for Preliminary Jurisdictional Determination
STIP BR-0160: Replace Bridge No. 15 on NC-179 BUS over the Calabash River
Brunswick County, NC
Dear Mr. Shaver:
Carolina Ecosystems, Inc. (CEI) has completed a delineation of streams and wetlands for the above
referenced project. The attached information, including required forms, tables, and figures, is submitted
for your review and preliminary determination of jurisdiction under the Clean Water Act (CWA).
Wetlands potentially under the jurisdiction of the Coastal Area Management Act (CAMA) have been
identified and the NC Division of Coastal Management (NCDCM) is copied on this submittal for their
verification of those resources.
Project Description & Methodology
As shown in Figure 1, BR-0160 is located near Calabash, NC at the NC-179 BUS (Beach Dr) bridge over
the Calabash River. This waterway is named Calabash Creek by the US Geological Survey (USGS) and
named Calabash River by the North Carolina Department of Environmental Quality (NCDEQ). For this
request, it will be referenced as Calabash River. The study area lies within the Lumber River Basin
(USGS Hydrologic Unit 03040208) and comprises approximately 12.3 acres.
This delineation was performed in compliance with methodology set forth in the U.S. Army Corps of
Engineers (USACE) Wetland Delineation Manual (USACE 1987) and subsequent guidance including the
Atlantic and Gulf Coastal Plain Regional Supplement. CAMA wetland areas were identified in areas
dominated by the current list of 10 coastal wetland species published by NCDCM.
Delineation Results
Figure 2 is presented using the Calabash, NC and SC (2019) US Geological Survey 1:24,000 Quadrangle
Map. Figure 3 presents the results of the delineation, which includes five wetlands, and one stream as
likely jurisdictional features within the project area.

August 3, 2021
Table 1 presents detailed information on each aquatic resource within the study area, including
latitude/longitude, estimated amount and type of aquatic resource in the review area, and geographic
authority to which the resource may be subject. Based on field data, there are approximately 1.70 acres of
wetland and 312 feet of perennial stream along the Calabash River.
We respectfully request your review of this information so that a preliminary jurisdictional determination
under the CWA may be obtained. If you have any questions, need additional information, or would like
to schedule a site visit, please contact me at your earliest convenience at (910)341-2036 or
tmherndon@ncdot.gov.
Sincerely,
Mason Herndon
Environmental Program Supervisor

1) The Corps of Engineers believes that there may be jurisdictional aquatic resources in
the review area, and the requestor of this PJD is hereby advised of his or her option
to request and obtain an approved JD (AJD) for that review area based on an
informed decision after having discussed the various types of JDs and their
characteristics and circumstances when they may be appropriate.
2) In any circumstance where a permit applicant obtains an individual permit, or a
Nationwide General Permit (NWP) or other general permit verification requiring “pre-
construction notification” (PCN), or requests verification for a non-reporting NWP or
other general permit, and the permit applicant has not requested an AJD for the
activity, the permit applicant is hereby made aware that: (1) the permit applicant has
elected to seek a permit authorization based on a PJD, which does not make an
official determination of jurisdictional aquatic resources; (2) the applicant has the
option to request an AJD before accepting the terms and conditions of the permit
authorization, and that basing a permit authorization on an AJD could possibly result
in less compensatory mitigation being required or different special conditions; (3) the
applicant has the right to request an individual permit rather than accepting the terms
and conditions of the NWP or other general permit authorization; (4) the applicant can
accept a permit authorization and thereby agree to comply with all the terms and
conditions of that permit, including whatever mitigation requirements the Corps has
determined to be necessary; (5) undertaking any activity in reliance upon the subject
permit authorization without requesting an AJD constitutes the applicant’s acceptance
of the use of the PJD; (6) accepting a permit authorization (e.g., signing a proffered
individual permit)or undertaking any activity in reliance on any form of Corps permit
authorization based on a PJD constitutes agreement that all aquatic resources in the
review area affected in any way by that activity will be treated as jurisdictional, and
waives any challenge to such jurisdiction in any administrative or judicial compliance
or enforcement action, or in any administrative appeal or in any Federal court; and (7)
whether the applicant elects to use either an AJD or a PJD, the JD will be processed
as soon as practicable. Further, an AJD, a proffered individual permit (and all terms
and conditions contained therein), or individual permit denial can be administratively
appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it
becomes appropriate to make an official determination whether geographic
jurisdiction exists over aquatic resources in the review area, or to provide an official
delineation of jurisdictional aquatic resources in the review area, the Corps will
provide an AJD to accomplish that result, as soon as is practicable. This PJD finds
that there “may be” waters of the U.S. and/or that there “may be”navigable waters of
the U.S. on the subject review area, and identifies all aquatic features in the review
area that could be affected by the proposed activity, based on the following
information:

species, with exotic plants absent or sparse within the assessment area.
B Vegetation is different from reference condition in species diversity or proportions , but still largely composed of native species
characteristic of the wetland type. This may include communities of weedy native species that develop after clearcutting or clearing.
It also includes communities with exotics present, but not dominant, over a large portion of the expected strata.
C Vegetation severely altered from reference in composition, or expected species are unnaturally absent (planted stands of non -
characteristic species or at least one stratum inappropriately composed of a single species), or exotic species are dominant in at
least one stratum.
16. Vegetative Diversity – assessment area condition metric (evaluate for Non-tidal Freshwater Marsh only)
A Vegetation diversity is high and is composed primarily of native species (< 10% cover of exotics).
B Vegetation diversity is low or has > 10% to 50% cover of exotics.
C Vegetation is dominated by exotic species (> 50 % cover of exotics).
17. Vegetative Structure – assessment area/wetland type condition metric
17a. Is vegetation present?
Yes No If Yes, continue to 17b. If No, skip to Metric 18.

20. Large Woody Debris – wetland type condition metric (skip for all marshes)
Include both natural debris and man-placed natural debris.
A Large logs (more than one) are visible (> 12 inches in diameter, or large relative to species present and landscape stability).
B Not A
21. Vegetation/Open Water Dispersion – wetland type/open water condition metric (evaluate for Non-Tidal Freshwater Marsh only)
Select the figure that best describes the amount of interspersion between vegetation and open water in the growing season. P atterned
areas indicate vegetated areas, while solid white areas indicate open water.
A B C D
22. Hydrologic Connectivity – assessment area condition metric (evaluate for riparian wetlands and Salt/Brackish Marsh only)
Examples of activities that may severely alter hydrologic connectivity include intensive ditching, fill, sedimentation, channelization, diversion,
man-made berms, beaver dams, and stream incision. Documentation required if evaluated as B, C, or D.
A Overbank and overland flow are not severely altered in the assessment area.
B Overbank flow is severely altered in the assessment area.
C Overland flow is severely altered in the assessment area.
D Both overbank and overland flow are severely altered in the assessment area.
