Hi Paul,
I am working on issuing this 401 and I noticed that the impacts for culvert #2 are listed as
136.7 ft, however the profile of the culvert shows that the culvert length is 140 ft. Given the
plan view shows that the stream exhibits sinuosity it seems there may be an error. Can you
double check this and send updated plans if appropriate.
Attached, please find a revised set of engineering graphics for your use. The 140 ft shown on
the profile was a typo. As you can see, the pipe does not begin at Station 0+00. The actual
pipe length is 135.49 LF and the stream impact length is 139.67 LF. The stream length was
also increased because the original graphics did not show the stream impact (in blue),
extending to the end of the pipe on both ends. We have attached a revised set of graphics that
corrects both of these issues.

Also, I noticed that neither impact area lists impacts for a riprap apron which is typically
required by the Erosion Control permitting agency. If that's added later they would be
required to submit a new application for a modification to the 401, or they wouldn't be in
compliance. Is that something you want to take time to look into further before I issue a
401?
The engineer of record has determined that rip rap aprons are not required for either crossing.
They have requested that NCDWR issue the 401 as currently designed. They also
acknowledge that if rip rap aprons are requested in the future, a new 401 application
requesting a modification to the existing permit will be required prior to conducting the work
(so the project will remain in compliance with 401).
