Anneliese,

DWR has reviewed the adjustment to extend riprap along the stream bank -11 linear feet at the
outlet of Culvert 1 (-L- Sta. 22+11) and to convert the existing mechanized clearing (wetland) impacts
to fill impacts (0.0015 ac). DWR agrees we can handle this via a field adjustment, please consider
this correspondence as the official approval. I will add the supporting documentation to the project
file.

Thank you,

Hannah

Annelise,

The Corps has reviewed the proposal to extend the riprap along the stream
bank 11 linear feet at the outlet of Culvert 1 (-L- Sta. 22+11) and convert
existing mechanized clearing (wetland) impacts to fill impacts (0.0015ac). You
may consider this as official approval of the proposed work and will note this in
the project file.

Hi Hannah and Tom,
I wanted to follow-up about the subject project’s proposed field adjustment for additional impacts.
As discussed on site on 2/1/2023, NCDOT would like to extend the riprap along the stream bank 11
linear feet at the outlet of Culvert 1 (-L- Sta. 22+11). The existing rock extending from the culvert’s
wing wall in this vicinity (see attached photo) was permitted as fill in wetlands. Therefore, by
extending the rock, we will be changing existing mechanized clearing (wetland) impacts to fill
impacts. Please see the attached permit drawing showing the approximate location of the additional
riprap along the stream. The additional rock will be within the permanent drainage easement. I
calculate the additional fill to be 66 square feet or 0.0015 acre.

We intend to construct this as a field adjustment. Please let me know if you have any questions or if
you need additional information.

Thank you,
Anneliese
