Hi Heath,
I concur with Andy's draft notes. Except that in addition to Sites 8, 9, 50 and 51 of which required "Remedial Action", I
would add the entries for Sites 25, 40 and 48 (highlighted in yellow in the attached) to the "Remedial Action" List as well.
As I recall, we all agreed that additional work was to take place on those sites as well.

Andy, FYI. Heath, Greg and I met at Site 50 with Marla last week to review the low flow sill and high flow side. As I
recall, Marla agreed with a plan to remove the low flow sill, then revisit at a later date to review and proceed from there
based on the level of functioning. Also, a sill at the outlet, and flood plain benches were to be constructed at the
inlet/outlet of the high flow side and backfilled.

Heath, Is that how we left it with Marla?

Remarks: During the site visit, the following�ermit sNo ites were inspected:
Sites 1 2 3 4 8 9 10 11 13 21 24 25 26 27 29 30 32 33 3� 40 42 45 46 47 48 50 51 54 55
and 56. Several of the existin�pipes had not been re�lace but rather, installed immediately
beside the existin�pipe via the jack and bore method. This was done primarily for safetX
reasons associated with keeping the road open to traffic during construction and was
coordinated with the USACE �rior to installation. The following observations were made
during the 15 September 2015 site inspection:
Site 1: A�proximately 15 linear feet of rip rap was installed on the downstream end of the
crossing for dissi�ation. The �ipe is still perched; however there is an im�oundment
immediatelv downstream. The �erched pipe should have limited im�act on aquatic life
movement.
Site 2: Durin� the site ins�ection, rip ra� was observed bein� placed within the �ermit area as
indicated in the project plans.
Site 3: Fill a�peared to have been placed within the permit area as indicated in the project
lp ans•
Site 4: Culvert was replaced with a bridge. Rip rap had been placed along the banks under the
Page 1 of 3

brid�e•
Site 8: The constructed culvert at this location was sli�htl�perched. NCDOT Division
Environmental Officer will provide recommendation for remedial action. Discussed the
installation of a lo� vane during the site visit.
Site 9: The �ermit plans indicate that 1721inear feet of stream was to be relocated at this site.
The work had been conducted a�roximately 3 weeks prior to the site inspection. The NCDOT
DEO will continue to monitor the relocation for stabilitv.
Site 10: The permit plans indicated rip rap would be installed at the outlet end. No ri� ra� had
been installed, but there did not a�ear to be any erosion issues.
Site 11: This culvert was replaced by borin_g and jackin� immediately beside the existing
culvert. A�proXimatel_y 30 linear feet of stream channel was relocated on the downstream,
outlet end of the culvert. This relocation was not indicated in the a�roved �lans. The channel
appeared stable and had a similar pattern, dimension and �rofile as the downstream receiving
stream se�ment. The be i�g of the stream is just u�slo�e of the u�stream end of the culvert.
No additional miti�ation would have been required for the 301f of relocation. Also, see Site 47
description re a� rdin� miti at� ion•
Site 13: The a�roved project plans indicated that 17 linear feet of stream would be
permanently filled at this site. The site inspection revealed that a�roximately 30 lf was filled.
This culvert was installed with the jack and bore method. The existing receivin� channel
downslo�e is relatively stee�. No additional miti�ation would have been rec�uired. Also, see
Site 47 description regardin� atg ion•
Site 21: This culvert was reali�ned, but no additional permanent loss of waters occurred.
Approximately 20 feet of rip rap was placed at the inlet end of the culvert. The rip ra� was not
shown on the project �lans.
Site 24: The crossing ap�eared to be constructed in accordance with the a�roved plans.
Site 25: This culvert was installed via jack and bore method. The existin� outlet will need to
have a small (�proximatel.�) channel installed to connect to the eXisting downstream
segment.
Site 26: This crossin�appeared to be constructed in accordance with the a�roved plans.
Site 27: This crossing a�eared to be constructed in accordance with the a�proved �lans. It
was designed with a"parallel end section", NCDOT personnel and contractors stated it was
not a good desi�n for the mountain areas, and should probably be avoided in most cases in the
future.
Sites 29 and 30: A�proximately 45 square feet of existin� wetlands had been excavated in
order to replace this project with the jack and bore method. It had been seeded and matted.
Site 32: No s�rin� box was installed at this site. The fill footprint a�eared to be �laced in
accordance with the ap�roved plans.
Site 33: This crossing a�peared to be constructed in accordance with the a�proved �lans.
Site 34: This culvert was installed adjacent to the existin�pipe, using the jack and bore
method. It resulted in a�proximately 15 linear feet of new channel at the outlet end to join it
with the downstream receivin� stream segment. The outlet end of the �ipe was scoured out
durin� a large storm event after the pipe extension was installed. Several cobble sized stones
had been tamped into the substrate to protect from additional erosion. Immediatel�pstream
of the culvert the stream was filled (Site 33) and no aquatic movement would occur throu�
the culvert at Site 34.
Site 40: The installed culvert is perched. The existin� stream is intermittent and the previous
pipe was also �erched, according to NCDOT officials and the site contractor. Pipe is resting on
existin� bedrock and could not have been buried. NCDOT will place a�roximatel_y 15 linear
feet of rip rap at the outlet end for a dissipation pad. These impacts were not shown on the
approved plan, but are needed to prevent additional scour. No additional compensatorX

miti�ation would be required. Also, see Site 47 description regarding miti atg ion•
Site 42: This crossing a�eared to be constructed in accordance with the a�roved plans.
During the site visit, NCDOT personnel indicated that the pipe needed to be extended into the
existing�ard for safety reasons. Google earth site images revealed that the stream within that
area had been previousl�piped and that the section of pipe would just be replaced.
Site 45: This crossing a�peared to be constructed in accordance with the a�proved �lans.
Site 46: This crossin�appeared to be constructed in accardance with the a�proved �lans.
Site 47: The a�roved �lans indicated that 125 linear feet of stream channel was to be filled.
The site ins�ection revealed that this segment of stream channel was actually relocated to the
ed�e of the ROW. The iill at this site did not result in a loss of 125 lf of stream channel,
although NCDOT still provided compensatory mitigation for this feature.
Site 48: Old channel was filled in accordance with the a�roved plans. NCDOT relocated
channel upslope of the culvert extension. This channel is showing signs of active erosion and
will need to be lined with ri� ra� to �revent sedimentation in downstream stream segments•
NCDOT has �rovided compensator.�gation for all stream loss.
Site 49: This brid�e crossin�a�peared to be constructed in accordance with the a�proved
lp ans•
Site 50: NCDOT will place a sill at the outlet end of the left descendin� barrel of the newly
constructed box culvert. Additionally, a floodplain bench will be constructed within the stream
channel below the barrel as discussed with NCWRC. The construction of the flood�lain bench
will not result in a loss of stream len�th, but will �rovide far better passage of aquatic life.
Floodplain bench plans must be provided to USACE prior to construction.
Site 51: The site ins�ection revealed that the permitted rock vanes failed. NCDOT will re-
installlo v� anes•
Site 54: This crossing appeared to be constructed in accordance with the a�proved plans.
Site 55 and 56: NCDOT constructed a new pipe next to the existin� pipe. No additional
impacts to jurisdictional streams and wetlands were required.
III. CONCLUSIONS Date: September 24, 2015
In Compliance: � Yes � No If No, (i.e., out of compliance), describe concerns:
See remedial action required, listed below.
Remedial Actions Required: �Yes � No If YES, describe actions to be taken:
Site 8: The constructed culvert at this location was slightly perched. NCDOT Division Environmental
Officer will provide recommendation for remedial action. Discussed the installation of a lo� vane durin�
the site visit. Site 9: The permit plans indicate that 172 linear feet of stream was to be relocated at this
site. The work had been conducted a�roximatel_y 3 weeks prior to the site inspection. The NCDOT DEO
will continue to monitor the relocation for stability. Site 50: NCDOT will �lace a sill at the outlet end of
the left descendin� barrel of the newly constructed box culvert. Additionally, a floodplain bench will be
constructed within the stream channel below the barrel as discussed with NCWRC. The construction of
the flood�lain bench will not result in a loss of stream length, but will �rovide for better �assage of
aquatic life. Floodplain bench plans must be provided to USACE �rior to construction.
Site 5 L• The site ins�ection revealed that the �ermitted rock vanes failed. NCDOT will re-install lo�
vanes.
