Subject: Request for Modification of the CAMA Major Development Permit, and
Revision of Section 404 and Section 10 Individual Permit, and Section 401
Water Quality Certification for the Proposed Replacement of Bridges 138 and
139 over the Neuse River on SR 14770 (Maple Cypress Road) in Craven County,
North Carolina; TIP Project B-4484. Debit permit fees from WBS No. 33723.3.1

References: Section 404/Section 10 Individual Permit, U.S. Army Corps of Engineers Action
ID SAW-2017-00829, issued May 5, 2020.

Section 401 Water Quality Certification No. WQC004214, NCDWR Project No.
20200142, issued March 24, 2020.

CAMA Major Development Permit, NCDCM Permit No. 45-20, issued April 14,
2020.

The North Carolina Department of Transportation (NCDOT) requests a modification to the above
referenced CAMA Major Development Permit to authorize the replacement of the existing 84”
culverts along Maple Cypress Road. Additionally, NCDOT is requesting modification or
reissuance of the referenced permits from USACE and NCDWR for this work.

The proposed changes, presented in the attached permit impact sheets, include replacing the
existing 84” x 62’ culverts with two 90” x 70’ culverts with headwalls. The original roadway
plans and permit drawings requested for an extension of the existing culverts and the addition of a
collar. Upon further evaluation during construction, a complete replacement of the existing
culverts was determined to be more practical and address long-term maintenance.

The previously permitted impacts for channel relocation have been removed from the attached
permit drawings. Although a channel is shown in this location, it remains inundated and provides
no hydraulic benefit to the system. The excavation in wetlands previously associated with the
channel relocation and the mechanized clearing impacts at the inlet of the culvert have been
changed to hand clearing, which has already occurred on site.

To accommodate construction and installation of the new culverts and headwalls, small
permanent fill and excavation impacts have been added to both the inlet and outlet of the
proposed culverts. These impacts are less than 0.01 acre in total, and do not result in an increase
to the impact totals noted in Table 1 below. The individual increases can be seen in the attached
permit impact summary worksheet.

Summary Table of Impacts

For comparison, Table 1 is an abbreviated version of the wetland and surface water impacts and
the changes in impacts due to the modifications described above. A decrease of 0.09 acre of
excavation in wetlands and 0.27 acre of temporary fill associated with the channel relocation is
offset by 0.36 acre increase in hand clearing in wetlands.

Proposed Mitigation

The proposed changes detailed above would decrease total permanent impacts to jurisdictional
wetlands from 2.5 acres (represented by cumulative individual summation, not rounded totals, of
impacts at Sites 1 and 2) to 2.4 acres. Total temporary impacts to jurisdictional wetlands are being
increased from 0.29 acres to 0.38 acres. These revised permanent and temporary impacts to
jurisdictional wetlands do not exceed the mitigation compensated through in-lieu fee payment to
the NCDMS in association with the original permits issued for this project.

Regulatory Approvals

CAMA Permit: NCDOT requests that the N.C. Division of Coastal Management review this
permit modification request and issue a modification for the CAMA Major Development Permit
issued April 14, 2020.

Section 404/Section 10 Individual Permit: NCDOT requests that the U.S. Army Corps of
Engineers (USACE) review this permit modification request and modify the Section 404/Section
10 Individual Permit.

401 Certification: NCDOT requests that the N.C. Division of Water Resources review this permit
modification request and reissue a Section 401 Water Quality Certification.

If you have any questions regarding this information, please contact me at [phone] or
[e-mail].
