Mason,
Thanks for speaking with me about these JD calls and I agree with DOT's assessment of
the sites. I further agree that the drainage ditch at site 1 may be cleaned out under the
maintenance exemption as defined in our regulation. The ditch clean out would not
extend any deeper than the bottom of the existing pipe.
Thanks for the opportunity to comment,
Brad

NCDOT is having flooding problems on NC 50 near the Duplin/Pender County Line.
Hydraulics as reviewed the site and recommended that we upsize some pipes and
cleanout sediment at the Site 1 outlet. Attached is a package that includes a location
map, aerial photo with descriptions of proposed work at each site, a LIDAR map of the
project area and photos of the inlet and outlet of all three sites.
Based on the information provided, we are proposing that Site 1 Inlet is not
jurisdictional & outlet id a tributary within the proposed project limits, Site 2 is a
tributary on both inlet and outlet and Site 3 is not jurisdictional. Please let me know if
you concur with this assessment.
The second question involves the cleanout of the outfall at Site 1. Our proposal is to use
the existing pipe invert plus the 20% burial and carry that elevation out 150 ft. with a
0.5% fall. If agree that this is a tributary can I do this as maintenance like we discuss on
Old Folkstone Rd or do I need to apply for NW3.

If you have any questions, feel free to give me a call. This is a priority for the Division
because the road has severely flooded several times in the past few months.
Thanks!
