The Project is the I-74/ US3ll and NC 68 (Eastchester Dr.) Interchange Ramp Replacement.
The meeting began at 12:30pm.
General Notes / Comments
• HNTB advised that drainage designs were submitted to NCDOT Hydraulics on 10/19/15 and that
they may be slightly different from the provided 4B Plans.
o HNTB added and that those designs could be reviewed as part of the 4B meeting if needed.
• Hydraulics noted that designs for this project will be in accordance with NCDOT's Post
Construction Stormwater Permit.
Sheet 4
• HNTB advised that structural BMPs will be evaluated and added in Quadrants B& C where
practical.
o HNTB added that the measures will likely be "media filters" and that there designs will be
coordinated with Hydraulics.
• NCDWR advised that Randleman Buffer Rules apply to this project.
• USACE questioned whether the wetland in quadrant C would be a total take.
o HNTB advised that the impact would be a total take of approximately 0.01 acres.
• USACE questioned the lack of jurisdictional streams on the 4B plans.
o NCDOT Roadway advised that the FS file would be revised to reflect the jurisdictional
streams in the current WET file.

Sheet 5
• HNTB advised that the preformed scour hole shown left of -LNB- Sta. 43+25 on the provided 4B
Plans is no longer required since the existing drainage is being retained.
o NCDWR/ USACE questioned whether improvements were required at either the pipe
outlet or downstream.
o Photos at the outlet of the 15" CSP and downstream area were reviewed and showed no
issues.
Sheet 6
• USACE questioned the amount of expected stream impacts for the outfall (Stream B) left of -Y-
Sta. 17+40.
o HNTB advised that stream impacts at this outfall would be less than 20 LF and classified
as bank stabilization with no rip-rap proposed in the stream bed.
• USACE advised that mitigation for these impacts would be at a ratio of 2:1.
Sheet 7
• USACE questioned the amount of anticipated stream impacts for the outfall (Stream A) left of -
Y1- Sta. 18+00.
o HNTB advised that stream impacts for this outfall would be approximately 200 LF.
o HNTB added that the project will eliminate a severe headcut at the existing pipe outlet
right of -Y- Sta. 39+20.
o Several photos of the existing conditions were viewed.
• USACE advised that mitigation for these impacts would be at a ratio of 2:1.
Sheet 8
• No Comments.

• Permitting for this project will be by "Nationwide Permit".
• USACE questioned whether this project would be impacted by a future 6-Lane project on NC 68.
o NCDOT advised that it would not.
• HNTB advised that noise walls have been proposed for this project but that no additional
jurisdictional impacts are expected.
• USACE questioned the need for a 4C meeting.
o All parties agreed that a 4C meeting was not required.
• Upon receipt from HNTB, NCDOT Hydraulics will distribute permit drawings for final review and
