Dear Madam:
NC Division of Water Resources (NCDWR) issued an on -hold letter on August 27, 2013
to address additional information required for making a permit decision. Please see
below, NCDOT's response to items listed in the letter:
Permit application
`Y Site 2a: Are there bank stabilization impacts on the bank of Little Crabtree Creek
associated with the tie in?
No, the bank stabilization stops short of Little Crabtree Creek.
2. Site S: Table 4 doesn't list temporary stream impacts for the work pads. Please
update.
Temporary impacts have been added to Table 4 and updated in the Revised Permit
Application Cover Letter.

;73. Site 10: Are there bank stabilization impacts to Long Branch associated with the tie
in?
No, according to the NCDOT Hydraulics Unit, the rip /rap stops short of Long Branch.
D4. Site 11: All of the flow for Long Branch is being collected and emptied into a UT to
Long Branch at site 11. Can this smaller UT handle the increased flow?
Yes, the pipe was sized to adequately handle the additional flow and Class I Rip /Rap will
be placed at the bend in the channel to dissipate energy.
(Amy Euliss email response - September 16, 2013) I am not concerned about the pipe
being sized correctly. Rather I am worried that the channel is too small to handle the
rerouting of flow. I see that you have rip rap at the outlet and in the bend, but what
about the portion downstream before the tie in with the Long Branch.
The flow is following the existing drainage pattern — NCDOT is upgrading some of the
pipes (30" to 42 ") but no new flow is entering the system (roadway drainage currently
flows to .this stream as well). The hydraulic engineers have determined that the bank
stabilization at Permit Site 11 should help stop the erosion in this area, but had no
concerns about-the stability of the tie in to Long Branch (the tie in is also currently
outside of NCDOT's R/W).
05. Site 22: A pipe is being removed and replaced with a bridge and a rip rap lined
channel. DOT has proposed to subtract the 40' of day - lighting from the mitigable
total. DWR does not give credit for day- lighting channels that aren't natural channel
design.
There is no Natural Stream Design at this site; however, the US Army Corps of Engineers
(USACE) has given NCDOT credit for day - lighting in the past and NCDOT is operating
on this assumption unless dictated otherwise by the Corps.
C"6 Site 16: Cumulative impacts to Big Crabtree Creek are greater than 150' of stream 2
impact, so you'll need to mitigate for the additional 82' of impact at site 16 °
Site 16 is mislabeled — it should be UT Big Crabtree Creek
✓7. Sites 25 and 26 are the same stream. Mitigation is required at both sites.
'Mitigation will be provided for this stream.
J 8. Site 28 and 28A are different streams, and individual stream impacts are less than
150'. Therefore, no mitigation is required.
Table 4 in the Revised Permit Application Cover Letter has been updated to reflect this
change.
9. I need temporary stream impacts broken out in linear feet.
Table 4 in the Revised Permit Application Cover Letter has been updated with temporary
impacts in linear feet.

10. In an email to Lori dated August 7, 2013; you noted that there were some issues with
the permit application. Can you confirm that the permit application I received is
correct. If not, please provide me with the most up -to -date- information.
You have the correct permit application; Lori Beckwith (USACE) , was referring to a
discrepancy between the stormwater management plan and the permit application.
Mitigation Plans
1. Please provide utility overlays on the mitigation plans.
Please refer to Appendix B of the Mitigation Plan (revised November 4, 2013).
jSite 5a: Please quantify the extent of the buffer that will be impacted by the utility
line. Please discuss what efforts will be conducted to minimize the impacts on the buffer
from utility line maintenance.
Appendix B of the Mitigation Plan includes the overlay of utility impacts to streams and
buffers. Appendix C in the Mitigation Plan includes the signed Memorandum of
Agreement (MOA) between NCDOT and Duke Energy. Under #4 of that MOA, sensitive
areas including endangered species and other areas deemed appropriate (mitigation sites)
are discussed. Duke Energy has also been provided a copy of the NCDOT -NES
Mitigation Geodatabase for use in maintenance operations related to NCDOT -owned
properties and right -of -ways.
jSite 8: Please quantify the extent of the buffer that will be impacted by the utility
line. What methods will be taken to minimize the impacts on the buffer from utility line
maintenance?
Please see response to Question 2 above.
CX Site 9: DWR requires mitigation for rip rap lined channels, -and doesn't see this site
as a viable candidate for mitigation.
NCDOT will receive mitigation per U ACE at this location. Please refer to the
Mitigation Plan (revised November 4, 20 3)
J5. Site 18: Please provide channel slope.
The channel slope at Site 18 is 3.94 %.
,,16. Sites 18 and 25: Due to the very short length, DWR doesn't see sites 18 and 25 as
viable sites for mitigation.
NCDOT is unaware of anv minimum len tg h requirements for stream mitigation Please
refer to Sections 3.0, 5.0 and 9.0 of the Mitigation Plan (revised November 4, 2013) for
sites 18 and 25.

�6r
7. Site 21: Please quantify the extent of the buffer that will be impacted by the utility
line. 4Please discuss what efforts will be conducted to minimize the impacts on the buffer
from utility line maintenance. Please provide channel slope.
The buffer will not be impacted by a utility line. It is being removed at this location. The
channel slope is 2 %.
8. Site 30: There's a small UT in the field that is being impacted from the stream
relocation. How will this channel impact the design? Jamie and I discussed this .issue
during our site visit. Also, you are currently proposing 1:2 mitigation. Our mitigation
rules only allow for 1:1 mitigation, therefore the DWR can only give you credit at 1:1.
Please refer to the revised Appendix A plan sheet for Site 30 which shows the tie -in of
the UT With the stream relocation site. Since there is minimal flow in this UT, the
channel dimensions will remain the same. In the initial conversations with USACE, it
was indicated that NCDOT should receive a 1:2 ratio for relocation of a poor quality
stream. After further discussions with USACE concerning mitigation ratios, NCDOT has
revised the ratio for this site .to 1:1.
NCDOT believes the above issues have been adequately addressed and changes have
been made to the original permit application and mitigation plan. If you have any further
questions or concerns please contact Jeff Hemphill (jhemphillancdot.Qov or 919 707-
6126).
