Zach,
Regarding the basins created for the installation of rip rap on the culvert. The response from the engineer is in the email
below in Green. Before I give a formal response I want to know how we can tie in 401 compliance as well. For one the
excavation of the stream bed and channel was not part of the permit, only riprap armoring (fill) of in the stream. This
structure would also seem to be a severe impediment to the flow of the stream beyond an armored culvert. I am in the
office this afternoon, if you called tomorrow use the work cell below since I will be teleworking.
Thanks,
Shane

Jeff,
I ended up in Wilson on another project yesterday and drove through to Wilson Ballfields for a compliance check on the
NWP-14 that was issued for this crossing. The permit had 117 linear feet of stream impacts for the culvert and rip -rap to
armor. I this large catch basin design that was used to armor the downstream side of the culvert is not shown in the
permits.
A dissipator pad was installed at the outlet of the 60" pipe to prevent erosion of the channel. The length of the
dissipator was included in the permit impact length and should have been better identified on the impact plans. Since
the pipe is buried below the stream channel, the tail end of the dissipator slopes up slightly to the natural stream bed
channel creating a bowl shape which is expected to fill in with time creating a more natural channel. Sides were also
armored to existing ground level per the NCDEQ Land Quality detail for stormwater dissipator pads. Please reference
attached copy of the Impact Drawings, with lengths of Impact further described (SEEAttached)
This designed was mirrored on the upstream side as well at about half the scale

The existing stream channel is very narrow with steep slopes and riprap was installed on the upstream side of the pipe
to protect the inlet from washing out and to tie back in to the natural grade.
and both upstream and downstream sides seem to be impeding the flow of water at low flow level.
We will be glad to remove some of the riprap where the existing channel ties in both upstream and downstream to
prevent impedance of stream flow. Please advise to what extent is acceptable.
The storm water catch basin was also not in the permit and it was unclear where it falls in relation to the wetlands,
This is a temporary sediment skimmer basin that was installed outside of the existing wetland areas which were
surveyed prior to site design. The basin is temporary and will be removed when construction is complete and
groundcover is fully re-established.
there are multiple flagging tapes all over the site from construction. There seems to be a lot of work on going so this
would be a time to address these issues before project completion.
Thank you for your attention to this matter,
Shane
