D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The existing culvert spans the property line between the subject property and the adjacent property to the north. It will be removed and the impacted
buffer restored. The new culvert will be centered under the new subdivision road entrance and is proposed as Gose as possible to the existing culvert
to minimize additional permanent impact while meeting NCDOT design standards.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
After replacing the existing culvert with the new culvert, the portion of existing impacted stream located on the adjacent property will be restored. The
net result will be 34 feet of additional permanent stream impact.

Marcus,
It was a pleasure meeting you the other day. As discussed, attached are the storm water calculations from our
Hydraulics Unit indicating that an 84" pipe would be necessary for Oakwood Acres. Please review and compare with
your works and then resubmit the site plan for us to review for the driveway permit. Once that is approved, we can
begin work on the submittal of the preliminary subdivision plat. Let me know if you have any further questions.

Carl,
Per your request please see the attached pdf file(s) with the information you requested. As far as the sills go yes this is
required based on the proposed slope of the culvert it is not based on the type of pipe. If you should have any
additional questions please don't hesitate to contact Mr. Paul Fisher, PE or myself via email or by telephone at (919)
707-6720 or [phone], respectively.
Thank you,

Shawn

Paul and Shawn,
Sorry for the lengthy time on this response but we unaware that the calculations in the previous email had not been
discussed with the project engineer, Marcus Barksdale. Is it possible for you to forward your storm water calculations to
us, as soon as possible, where the size of the culvert (ie 84") was determined. Also, the indication that sills should be
provided to help retain the bed material in the pipe; is that for all types (is CMP, HDPE, RCP) of culverts proposed?

Carl,
I apologize for the confusion on this review. We believe the proper pipe size of the culvert should be 84" with a
headwall and a 12" bury. Also, since the culvert is proposed to be on a 5% grade, sills should be provided to help retain
the bed material in the pipe. Please refer to Shawn's link to sill design if needed. Although I did not see ditch
calculations, it appears that all of the ditches are called to be lined. This will be acceptable, but the subdivision should
not be accepted for maintenance until all he ditches are actually stable.
If you need anything further on this, please advise.
Paul

Shawn,
We are confused at the review comments provided. Have these comments been discussed with the engineer designing
the Oakwood Acres and the person that prepared and submitted the calculations, Mr. Marcus Barksdale? The DOT has
been requested to take over this proposed subdivision road and culvert and we would like for you to confirm that the
documentation provided will allow us to take the proposed road over for maintenance without having to upgrade any
undersized culvert (?) in the future.

Carl,
The Hydraulics Unit has completed its review of the submitted materials for the above mentioned project and or
comments are as follows.
Please be informed that End Treatment/Headwalls are to be placed on cross -pipes 36 inches or larger, please
provide calculations that reflect this and select a NCDOT approved headwall from the Roadway Standards
Drawing manual (Section 9.5.1.2) or provide a detail for our review. We have provided a link to assist you with
this request. Click Here

Please submit ditch calculations that are clearly labeled for easy identification and coincide with your plans for
our review.
• Upon our review we noticed that the proposed slope of your culvert is listed as 0.056 ft./ft. which exceeds the
minimum slope allowed without installing sills/baffles. It will be necessary for the proposed culvert to have
these, we recommend the sills/baffles to be oriented as follows: One to be located 5 ft. inside each end with
two (2) located equally spaced within the remaining 58 ft.. Please see the provided link for reference. Click
Here
If you should have any questions or concerns please don't hesitate to contact Mr. Paul Fisher, PE or myself via email or
by telephone at [phone] or [phone], respectively.
Thank you,
