SUBJECT: Application for Section 401 Water Quality Certification and Neuse Riparian
Buffer Authorization for the proposed widening of the I-540 ramp at Falls of
Neuse Road, Wake County, Division 5. F.A. Project No. NHPP-0540(030), T.LP
Project Na I-5710; Debit $270 from WBS No. 50125.1.FS1
Dear Sir:
The North Carolina Department of Transpartation (NCDOT) proposes to widen ramps in four
locations along I-540 in Wake County. Of these sites, jurisdictional impacts will occur at only
the Falls of Neuse Road location. There will be <0.01 acre of temporary impact to an unnamed
tributary to Falls Lake due to the installation of a rip rap apron at the outfall of a 15-inch
stormwater pipe. Total impacts to the Neuse River Riparian buffers are 1,837 square feet.
Please see the enclosed copies of the Pre-Construction Notification (PCN), stormwater
management plan, perinit drawings, buffer impact drawings, and roadway design plans for the
subject project. A Programmatic Categorical Exclusion (PCE) was completed for this project in
Apri12016 and distributed shortly after completion. Additional copies are available upon request.
This project calls for a letting date of September 20, 2016 and a review date of August 2, 2016.
Regulatory Approvals
Section 404 Permit: We anticipate that due to the limited impact of the project, Nationwide
Permit 3 would be applicable. No written authorization is anticipated for the project.
Section 401 Permit: We anticipate a 401 Water Quality Certification number 3883 and Neuse
River Buffer Authorization will apply to this project. NCDOT is requesting written concurrence
from the North Carolina Department of Environmental Quality, Division of Water Resources.

General Project Narrative: Project involves widening of I-540 on ramps, from single lane to double lane, at four locations to accommodate installation of ramp metering and other ITS/signal equipment.
Four locations are I-540 WB at (1) Leesville Road, (2) Creedmoor Road, (3) Six Forks Road, and (4) Falls of Neuse Road. Stream and Buffer impacts occur at only the Falls of
Neuse ramp due to the installation of slope drains/outfall protection, and a retaining wall located on the embankment slope.

Additional Comments
High velocities exist due to 15" slope drains on steep slopes. However, the volume of flow is very minor relative to full flow depth. For the pipe at 7+60 q/Q = 0.08, and for the pipe at 9+50
q/Q = 0.02. Minimum riprap aprons dimensions were computed in accordance with HEC-14, Chapter 10. Given the low flows, the aprons were very small. The proposed design uses wider
and longer apron dimensions, exceeding HEC-14 requirements.
' Refer to the NCDOT Best Management Practices Toolbox, Version 1(March 2008), NCDOT Standard Details, the Federal Highway Administration (FHWA) Hydraulic Engineering Circular No. 14 (HEC-14),
fhird Edition, Hydraulic Design of Energy Dissipators for Culverts and Channels (July 2006), as applicable, for design guidance and criteria.
