Your concern is why I prefer Option 1 because we can grade the tributary to a 0.1% slope within the 40 ft reach and tie
into the new ditch at grade. I believe this the best option for stability and drainage plus not interfere/overwhelm our
roadway drainage through the 30 culvert @ -Y1-.

AW,
I really don't have any comments or questions being that the impacts are related to a JS non mit. Whichever strategy the
Division chooses would be fine with me.
I am curious how they are going to make up the foot elevation difference between the JS non mit and the receiving ditch
which sits one foot higher in elevation.

Joanne and Brad,
Chris Rivenbark has coordinated with Moffat and Nichol regarding the drainage along Little Loop Rd at Brunswick Bridge
47 (B-4438). Please see the 4 options that are presented below. Presently, I think Mason is leaning toward one that
doesn't have a junction box or pipes so that the drainage would be open. Specifically he thinks that the one with 40
"feet" of additional impacts could be the best option.
Do either of you have any comments or concerns regarding these options?
We also plan to discuss these options with NCDOT maintenance.
Thanks,
Anneliese

The design firm has come up with three possible options. Can you let us know which you would prefer?

Chris / Jacquelyn,
Please see below the options we have come up with to solve this JS non-mit ditch issue. Please let us know if you have
any questions or need additional information.
Regards -
Trent
To provide positive drainage (0.1% grade) from the JS non-mit to the proposed base ditch we would have to wrap the
ditch around the end of the proposed cross pipe and extend the grading of the JS non-mit back to around station 10+65
Y1 which would be around 40' of additional stream impacts along Little Loop Road. This is according to the survey we
were provided to design the project.
3
Another option would be to not increase impacts but to grade the JS non-mit in the radius of the intersection as it
transitions from cut to fill and tie into our proposed base ditch. This would result in a low spot in the JS non-
mit. However we would not expect this to cause any flooding issues.
Another option would be to add in a Junction Box with pipe stubs. The pipe going to the JS non-mit would have an
adverse slope and would potentially create a low point.
Still another option would be to add the JB with pipe but extend the pipe back far enough to achieve a positive grade in
the pipe (0.1%). Again this would add additional impacts to the JS non-mit.

Trent,
The agencies made a compliance inspection on Tuesday and have additional questions.
The note below is from the Div. Env. Specialist.
6
Regarding the note on permit drawing 6: the agencies reviewed this site in the field yesterday. Both the Corps
and DWR are interested in how the existing drainage along the east side of Little Loop Rd. (a JS non mit) will tie
to the created special lateral base ditch. The base ditch has already been graded by the contractor. The
attached photo shows the base ditch -the water in the foreground is the JS non mit. The photo was taken from
Little Loop Rd facing the base ditch. The contractor indicated that grade shots show that the base ditch is about
1' higher than the bottom of the JS non mit. Therefore, we are looking for some guidance on how to connect
these drainages — either by grading or with a box and pipe stubs.
Also to explain a change from your previous version, I removed the existing channel impacts temp (linear amounts) from
sites 1,2, & 7 from the impact summary sheet. The JS non-mit impacts only need to be provided in ac.
If SMU approves, please take a look at this and make any necessary revisions.
