As described below this work will require very minimal in water disturbance and therefore WRC is
not requesting NCDOT to adhere to an in water work moratorium for this project.

Travis:

Per our phone conversation last week I am following up with you concerning the in water work
moratorium for anadromous fish in Lake Mattamuskeet and the proposed maintenance of the
existing riprap scour pads for culverts no. 2, 16, and 18. Monitoring of the culverts conducted by
NCDOT bridge maintenance staff has discovered subsidence of the scour pads adjacent the culvert
toe wall. The subsidence has exposed 2 to 3’ of the toe wall and will require between 9 to 16 cubic
yards of riprap to eliminate the toe wall exposure. Culvert no. 16 will require work on the east and
west side while culvert no. 2 and 18 on the east side only. Placement of the riprap will be done with
an excavator working from the bank on the north and south side of the culvert. Granite will be
trucked to the site where the excavator will grab the granite directly from the dump truck for
placement. The in water work should not take more than a couple hours per culvert once the
granite and equipment is in place. I attached the original permit drawings for Culvert no. 2 for
reference.

Please respond concerning whether NCDOT should adhere to the anadromous fish moratorium
while conducting this work. Thank you for your time and I look forward to hearing from you.
