The 4B meeting began with Paul Atkinson (NCDOT) giving a brief overview of the project and that he would
go through the project sheet by sheet.
Sheet 4:
Wetland 241: There is a small portion of wetland impacted by the proposed fill slope at approximately -L- Sta.
23 +00 RT. Hydraulics is proposing ending a ditch at the wetland boundary without any
additional impacts to the wetland. There were no comments associated with this wetland.
Sheet 5:
Wetland 241: The edge of this wetland is being impacted by the proposed fill slope in the wetland from -L- Sta.
23 +00 to 28 +50 RT. Hydraulics is proposing ending a ditch at the wetland boundary without any
additional impacts to the wetland. There were no comments associated with this wetland. This
site is a continuation of the previous sheet.
Wetland 242: This is a total take of this wetland due to fill from the -L- alignment. There were no comments
associated with this wetland.
Sheet 6:
Wetland 2: There were no comments associated with this wetland and no impacts are anticipated.
Sheet 7:
Wetland 30: No impacts are anticipated with this wetland.
Wetland 31: Division 2 asked whether the proposed ditch should end at the wetland boundary. Hydraulics
stated that the proposed ditch is tying into an existing ditch that goes through the wetland
currently.
Wetland 32: USACE requested that Hydraulics avoid ditching through this wetland which is surrounded by the
new -L- and -Y1- alignments and the existing US 17. Hydraulics will investigate ending the ditch
at the wetland boundary.
Sheet 8:
Wetland 27: This is a large wetland that is being divided by the -L- alignment. Hydraulics is proposing two
36" RCP Equalizer Pipes without headwalls that are not to be buried to allow water to flow freely
between the wetlands. USACE requested that Hydraulics include the rip rap at the median
drainage outlet in the wetland at -L- Sta. 74 +27 RT as permanent impacts.
Sheet 9:
No impacts /comments.

Sheet 10:
Wetland 26: This wetland is crossed by both the -L- and -Y2A- alignments. Hydraulics proposed the use of
toe protection in the wetland at approximately -Y2A- Sta. 30 +50 to 31 +40 RT. and -L- Sta. 99 +50
to 101 +25 LT. USACE requested for ditches to end before reaching the wetlands instead of
ditching through the wetland as Hydraulics had proposed. USACE asked for bank stabilization at
bend in Cotman's Branch at outlet of 60" RCP cross pipe under -Y2A- Sta. 31 +50.
Sheet 11:
No impacts /comments.
Sheet 12:
Wetland 22: This wetland site is being impacted by fill from the new alignment of -Y2D -. There were no
comments associated with this wetland site.
Wetland 24: This wetland site is impacted by the cut from the -L- alignment and the fill from the -Y2D-
alignment. Hydraulics is proposing ending a ditch at the wetland boundary with no additional
impacts. USACE requested that the wetland would be a total take between the two alignments. It
was agreed that these impacts would be reflected as a total take of the sliver between the two
alignments at -L- Sta. 129 +00 RT.
Sheet 13:
Wetland 44: This is a wetland site that is being impacted by fill from the -L- alignment. There were no
comments associated with these impacts.
Wetland 245: This wetland is a drainage ditch that is crossed by the -L- alignment. Hydraulics is proposing a
cross pipe at this location. Hydraulics has also proposed ending a ditch at the wetland boundary,
but not causing any additional impacts. There were no comments associated with this wetland
site.
Sheet 14:
Wetland 45: This site involves Higgin's Branch which is jurisdictional. The stream is being spanned with a
bridge of yet to be determined length. The impacts will be due to the piers and rip rap at the end
abutments of the proposed bridge. This large wetland is crossed three times by the proposed
alignment. Hydraulics is proposing two 36" RCP equalizer pipes to be installed. USACE and
Division 2/3 requested that equalizer pipes not be buried and that the equalizer pipe at -L-
centerline Sta. 158 +00 have a reduced skew. Division 3 also mentioned there being a safety issue
with pipes extending out beyond the fill. Hydraulics will reexamine the skew angle of the
equalizer pipes.

Sheet 15:
Wetland 42: This wetland site is being impacted by the fill from the proposed alignment at Sta. 163 +00 RT.
Hydraulics is proposing day - lighting two ditches into this wetland from either side. There were
no comments associated with this wetland.
Wetland 45: This site is continued from the previous sheet.
Wetland 46: This site involves the White Oak River which is jurisdictional. The river will be spanned with a
bridge of yet to be determined length. The impacts will be due to the piers and possibly the rip
rap at the abutments of the proposed bridge. USACE asked if lengthening the bridge would affect
the roadway grade, which Roadway stated that it would not have an effect. PDEA stated that the
proposed bridge is already 30' longer than the previously- agreed length.
Sheet 16:
Wetland 46: This site continues from the previous sheet. DWQ asked about bridge drainage to which
Hydraulics said that deck drains would not discharge directly into the water.
Sheet 17:
No impacts /comments.
Sheet 18:
Stream W21: This stream is a large jurisdictional stream that is crossed several times by the proposed
alignment. Hydraulics is proposing realigning the stream where it is impacted by the proposed
fill slope. Where the alignment of -Y3A- crosses the stream, Hydraulics is proposing a cross pipe
at this location. There will be rip rap protection at the outlet of the cross pipe. USACE requested
that headwalls be placed on the cross pipe no matter the size. DWQ was concerned with the slope
of the stream realignment. Hydraulics will design the slopes to match existing conditions where
possible.
Sheet 19:
Stream W21: This is a continuation of the site from the previous sheet. On this portion of W21, the proposed
roadway alignment completely covers the stream requiring realignment. DWQ asked that the
cross pipe at -L- centerline Sta. 220 +00 have the skew improved to prevent an abrupt angle into
the ditch at the outlet. USACE asked about the size of the cross pipe. Hydraulics has yet to
determine the size of the cross pipe, and will also investigate the possibility of improving the
skew of the pipe. Hydraulics also proposed rip rap at the toe of fill in the channel, -L- Sta.
215 +50, to stabilize the banks where the existing channel is being filled and the new channel ties
back in to the existing.

Sheet 20:
Stream W21: This is a continuation of the site from the previous sheets.
Wetland 49: This wetland is being crossed by the proposed alignment. There are no hydraulic strictures
involved with this site on this project which adjoins R- 2514C. There were no comments
associated with this site.
Sheet 21:
No impacts /comments.
Sheet 22:
Wetland 26: This site is the continuation of a site from sheet 10. This site involves a jurisdictional stream.
The stream and wetland are being impacted by the fill from the proposed alignment. Hydraulics
is proposing a realignment of the stream where it is cut off by the proposed roadway fill. USACE
requested that Hydraulics armor the bank of the stream at the location of fill, to which Hydraulics
noted that the armor had gotten erased during revisions and rip rap was added to the plans at the
meeting.
Sheet 23:
USACE noted that there is a conflict with flow arrows located in a non jurisdictional stream. Hydraulics will
investigate further.
General Comments:
USACE requested a copy of the Hydraulics proposed drainage plans used during the 4B meeting. Copies were
provided to participants by email on 10/12/12.
DWQ asked for grass lined ditches to be used if possible.
