Nikki,
The explanations for the revisions are acceptable. We approve the additional impacts as described. To keep it simple, we’ll
approve the revisions using this email. I’ll place the information you sent including the revised drawings in the file for future
reference. Thanks.

Kristi,
Make this version 2 in BIMs. I’ll enter the additional impacts. Thanks.

Dave W.

Good morning Dave!

I’ve attached some documents to this email regarding Bridge 254 in Guilford County on Ferguson Road. While we were at the
preconstruction site meeting yesterday, we discovered that in the northeast quadrant of the project there is not enough room
to construct the wing wall. Therefore, after an emergency meeting with the designer and the team members, we have pulled
together a revised set of buffer drawings and updated the summary sheet to show this additional area need for construction
1

(263 square feet in Zone 1). The design engineer has offered the below narrative (based upon our onsite discussions yesterday)
as to the need for this slight increase.

It is my hope that we can handle this via email – however, if you need me to resubmit everything, please let me know. I’ve also
included the original DWR authorization.

Thank you so much!

Nikki

N,

Per our filed meeting and discussion today, please find attached revised Buffer Impact Permit drawings and updated summary
table. You will note the additional buffer impact area has been added as a separate line in the summary. Below is the
accompanying narrative for the additional area:

On the NE quadrant of the subject project, existing ground is approximately 8-10’ higher than the bottom of footing elevation
for the proposed culvert wing wall. Excavation for the wing wall must be sloped back for worker safety, thus resulting in
buffer impacts beyond those initially anticipated for the project. Consideration was given to utilizing sheet piling to contain
the excavation and limit buffer impacts, however the presence of aerial power and telecommunication lines directly over the
end of the proposed culvert precludes the installation of sheet piling. Upon completion of the construction of the culvert and
wing wall, the areas excavated within the buffer will be backfilled, restored to natural contours and seeded with native
grasses per the project special provisions.

Please advise if you have any questions or need additional information. We greatly appreciate your help in submitting this
information to the agencies and coordinating their review and approval. Thanks, TNP
