Attention: Mr. Garcy Ward

Dear Sir:
NICHOLAS J. TENNYSON
SECRETARY
Subject: Permit Modification Request for Section 401 Water Quality Certification
and Tar-Pamlico Buffer Authorization for the construction of a new rest area
along US 17 near Chocowinity in Beaufort County; TIP Project K-3800; Federal
Project No. N�HS-] 7(32); Debit $570 from WBS No. 38748.1.1.
References: 401 issued 8/9/13, DWR Project No. 20130649, modified 5/16/14
The North Carolina Department of Transportation (NCDOT) applied for permit authorizations
for the subject project on June 19, 2013. This application indicated that there were no expected
impacts to streams or buffers due to utilities. NCDOT requested a modification to the permits to
account for additional impacts, and these modifications were approved in May, 2014. The
project was let to construction in January, 2014.
Additional coordination has taken place to refine the on-site mitigation plans for the project.
Specifically, NCDOT is requesting a revision to the scheduled maintenance for Areas "A" and
"B" as depicted on the attached map and in the attached maintenance schedule.

As part of our request, NCDOT is proposing to allot the remaining buffer mitigation to this

A total of 81,457 sq.ft. of planted buffer mitigation is being offered to offset the 22,226 sq. ft.
of farm feld buffer impacts.
The maintenance schedule for Area "C' will remain as originally proposed.
It was determined during discussions with DWR that the planting density associated with the
buffer mitigation plan was sufficient for this site. This planting density is currently I15
trees/acre. The trees that were planted in this buffer area were 3 gallon containerized material.
Success criteria for planting densities for this site will be adjusted to reflect this change in
planting density. NCDOT proposes that the site meets vegetation success criteria if 115
trees/acre are surviving after 5 years.
Regulatory Approvals
Section 401 Certification: NCDOT requests that the NCDWR issue a modification for the
General 401 Water Quality Certification issued August 9, 2013, as required for the above-
described activities.
Tar-Pamlico Riparian Buffer Authorization: NCDOT requests that the NCDWR issue a
modification for the Tar-Pamlico Riparian Buffer Authorization issued August 9, 2013, as
required for the above-described activities.
A copy of this modification request will be posted on the NCDOT Website at
