Subject: RE: Dredging in Hatteras Inlet
Mr. Willson,
This Office apologize for being unable to participate in the pre -construction conference call on September 7, 2017 and
appreciates your continued coordination with Division of Water Resources per conditions 3, 4, and 5 of the individual 401
Water Quality Certification issued on August 28, 2016 under DWR Project No. 13-1279 V2. This Office approves the
one time dredging event utilizing the use of a sidecast dredge for southern connector canal as depicted in Drawing PV -1
dated September 7, 2017. This Office requests that a more detailed map showing historical SAV bed locations be
provided to ensure an adequate buffer is maintained.
If you any more questions, please feel free to contact me.
Regards,
Anthony Scarbraugh

Subject: Dredging in Hatteras Inlet
Mr. Scarbraugh,
I wanted to follow up with you on the Hatteras Inlet connector channel project, specifically with regards to the condition
that recommends dredging be conducted during outgoing tides only. As we've discussed in the past, restricting dredging
to outgoing tides would significantly impact the time required for the dredge to conduct the work. The USACE has
informed us that they want to dredge on a 24 hour schedule for this project as they are trying to clear the dredge's backlog
before it goes in for some major repairs. Furthermore, we believe that since the dredging for this maintenance event will
occur much closer to the inlet throat and considerably further away from previously mapped SAV, the maintenance is
much less likely to have an adverse impact with regards to sedimentation.

Please feel free to reach out to me if you have any further questions regarding the project.
Kind Regards,
APTIM
