RE: Pre -Construction Notification: Nationwide Permit 13, General Certification No. 4087,
and Neuse River Buffer Authorization
City of Kinston Lincoln Street Bridge Scour Countermeasures
Lenoir County, North Carolina 2 0 1 7 1 3 2 4
Dear Mr. Pelletier:
Carolina Ecosystems, Inc. (CEI), on behalf of the City of Kinston and Wetherill Engineering,
Inc., has prepared the attached pre -construction notification (PCN) for the above referenced
project for a Clean Water Act Section 404 Nationwide Permit 13, Section 401 Water Quality
Certification No. 4087, and Neuse River Buffer Authorization.
The City of Raleigh is proposing scour countermeasures at an existing bridge on Lincoln Street
over Adkin Branch. Excessive scouring was caused by Hurricane Matthew in October 2016. The
proposed rip rap installation along the bed and bank of Adkin Branch, up to the original stream
bed elevation level prior to Hurricane Matthew, will permanently impact 50 linear feet of Adkin
Branch. Proposed impacts to riparian buffer zones at this site are 950 square feet of Zone 1
impacts and 665 square feet of Zone 2 impacts (see attached buffer impact drawing). These
impacts are classified as "allowable" under the Neuse Buffer Rules. The buffer area will be
allowed to revegetate to current conditions once construction is complete. Wetland impacts are
not anticipated since no wetlands were found on site.
The preceding information, along with the enclosed PCN, project aerial map, USGS map, and
permit and buffer impact drawings are being submitted for your review of this project.
Installation of scour countermeasures at the Lincoln Street bridge is anticipated to begin at the
end of October 2017, therefore your prompt review and approval would be greatly appreciated.
Sincerely,
Gregory W. Price
Senior Scientist

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Rip rap will only be placed in scoured areas up to the original bed elevation prior to Hurricane Matthew. Existing bridge will
remain in place during repairs. Stormwater BMPs will be implemented, upon approval by the City of Kinston, and conform to
the requirements of the Neuse buffer rules. The areas of buffer impact will be allowed to revegetate to previous conditions
upon contruction completion.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Sediment and erosion control measures will be implemented according to NC requirements, and approved by NCDEQ prior to
implementation. Jurisdictional areas that are not permitted to be impacted and are adjacent to construction areas will be
clearly marked with protection fencing or other similar method to avoid inadvertent encroachment. Copies of the issued
permits and impact areas will be provided to the prime contractor and all subcontractors working in or near jurisdictional areas.
