Hey Chris,
Did your client decide how they wanted to deal with the question of the riprap pad? When we talked by phone you
were going to talk to the engineer again and get back to me? Thanks.

Sue/Andy,
Please see the attached pdf documents detailing your comments below. With regards to your comments concerning
the riprap dissipater, we have had conversations with DLR. It is our hope that we may communicate further with you as
DLR wasn't firm in their understanding of our application. It is our understanding that since we will not be discharging
from a point source into a stream, but instead replacing an existing pipe within a stream and burying that pipe per the
401 standard condition, rip-rap dissipation would not be necessary. Please contact us at your earliest convenience so
that we may discuss and hopefully resolve the issue and answer any other questions you may have.
Thank you,

Hello Chris,
I know your client is anxious for this permit to be issued so I'm contacting you via email about a couple things that I
need. If you prefer to deal by formal letter, just let me know.
In order to ensure that the conditions of the 401 will be met, I need:
• a detail sheet for the dewatering/pump around sequence - and be sure it includes a statement that all areas
will be restored to natural conditions upon removal of the dewatering measures (they have to match the
natural stream depth/width)
• have you verified that DLR is not going to require a riprap dissipater pad at the end of your culvert (this would
mean potentially more impacts than from the pipe alone)
• if they do require a riprap pad, I'll need a detail on the installation to ensure that the riprap is installed so that
the top of the riprap is at the same elevation as the bed of the stream.
• A profile of the pipe to show that the pipe is buried per our 401 standard condition
If you have any questions just let me know.

404/401 Permit (Nationwide 39) Application
Walmart Store #3036-00 (Yanceyville, NC)
Yanceyville, Caswell County, NC
Dear Mr. Williams and Ms. Homewood:
On behalf of Walmart Real Estate Business Trust, Kimley-Hone and Associates,
Inc. is submitting additional information as requested by your agencies in
conjunction with the joint 404/401 Preconstruction Notification Application
submitted on February 23, 2011 for authorization to construct the above
referenced retail building and associated parking lots under Nationwide Permit
#39 and General 401 Water Quality Certification number 3821. The following
requested additional information is included as part of this application submittal:
® Project Summary Sheet
a Pre-Construction Notification Form
® Revised Figure 5 - Impact Area Map (NAIP 2010 Caswell Co. Aerial)
® Construction Plan Drawings
The proposed project seeks to construct a new 14,869 square foot commercial
retail building with associated parking lots on an approximately 5.3+/- acre tract.
The proposed design also incorporates the construction of a wet detention basin
to treat runoff from the newly constructed impervious area. The project will
result in permanent impacts to 105 linear feet of a perennial RPW from the
replacement/realignment of a 48" CMP and installation of a rip-rap dissipater.
The project requires 35 linear feet of temporary impacts to install sand bags and a
pump-around to allow work "in the dry".

The original proposed design has been modified per the requirements ordered by
the NC Division of Land Resources which requires discharge velocities to be
`non-erosive'. In addition to the original 81 linear feet of permanent impacts the
new proposed design requires an additional 24 linear feet of permanent rip-rap
dissipation at the pipe outlet to reduce discharge velocity and meet `non-erosive'
design criteria. Other design measures utilized to meet `non-erosive' design
criteria include the addition of a drop manhole to reduce the slope of the
proposed pipe, as well as burying the pipe 1' below the existing channel bed.
Please feel free to contact me at [phone] if you have any questions, or if
additional information is necessary.
Sincerely,

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 site layout was designed to limit the amount of impacts to the stream while providing safe and effective routing for store
operations. A retaining wall has been placed at the end of the impacts to further reduce impacts to the stream. Additionally, a
wet detention basin has been designed to remove 90% of Total Suspended solids. The basin will also meet the pre-
development stormwater condition for the 1-yr, 2-yr, and 10-yr 24 hour storm events.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
An effective erosion and sedimentation control plan has been developed to minimize the impacts to the existing stream. The
plan is to reduce as much stormwater flowing to the stream during construction by way of lined diversion ditches that will flow
to sediment traps/basins. To handle the off-site flow, the area in front of the existing upstream inlet will be dammed with
sandbags. A temporary pump will be used to pump clean water around construction activity. In addition, the limited water that
will pass through the existing stream will pass through a rock check dam prior to entering the unimpacted portion of the stream
during construction.

2a. Does the project require Compensatory Mitigation for
impacts to Waters of the U.S. or Waters of the State? ® Yes ? No
