Michael,
I've reviewed your application for a 401 Water Quality Certification for the replacement
of Bridge No. 159 over Pungo Creek on Jones Bridge Rd in Beaufort County. I will need
the following information before I can finish processing your request:
• The plans call for a ditch being cut through the buffer to the stream in the
northeast quadrant. Currently there is no ditch outlet to the stream in this
quadrant and it appears that the water actually flows away from the stream
(south to north) and drains to a low point approximately 100' away from the
bridge. This is in agreement with narrative in the SMP which states: "The ditch
in the northeast quadrant will flow from south to north to match existing
drainage patterns." DWR prefers that no new ditch be cut in this quadrant as
that could destabilize the stream bank and increase the potential for sediment
deposition in the stream. Please let me know if the proposed ditch can be
eliminated in this quadrant.
The proposed ditch in the NE quadrant at the bridge has been eliminated, The
existing drainage pattern will be maintained flowing line ahead form the bridge
to the low point.
It appears that the existing ditch in the northwest quadrant may meet grass
swale criteria with 3:1 or flatter front and back slopes. If this is the case, it can
be used for treatment and included in the SMP.
A portion of the proposed ditch in the NW corner will qualify as a swale from
Station 22+00 to 24+00 (LT side) with a 3:1 front slope and 4:1 back slope has
been included in the SMP.
Agent information was not included in the ePCN that was submitted for review
in Section B. 1e. Please provide this information.
Robert has provided the information in an email on 5/20/2019.
Accordingly the application will be placed on hold pending resolution of the above
items. Please let me know if you have any questions.
