Can you update BIMS and the MRO spreadsheet and put my email in LF as a "more info requested" for us. You can
reassign it to me in all those locations when you are in there. Thanks.

Hi Jennifer,
Arnie passed this along to me for some input. While I understand that a no -rise situation is required, DWR requires
that: "Culverts shall be designed and installed in such a manner that the original stream profiles are not altered and
allow for aquatic life movement during low flows. The dimension, pattern, and profile of the stream above and below a
pipe or culvert shall not be modified by widening the stream channel or by reducing the depth of the stream in
connection with the construction activity. The width, height, and gradient of a proposed culvert shall be such as to pass
the average historical low flow and spring flow without adversely altering flow velocity. If the width of the culvert is
wider than the stream channel, the culvert shall include multiple boxes/pipes, baffles, benches and/or sills to maintain
the natural width of the stream channel. If multiple culverts/pipes/barrels are used, low flows shall be accommodated
in one culvert/pipe and additional culverts/pipes shall be installed such that they receive only flows above bankfull."
That is standard language in all of our General and Individual Certifications. The design must address the no -rise in such
a way that the base flow remains the same dimensions/width.
In addition, your response does not indicate how baseflow width will be maintained through the riprap apron at the
culvert outlet.

Please provide a design that meets this requirement. The Division will consider this project on hold until receipt of a
response. Please copy by Amie and I on the response.

Amie,
Please see the attached revised stream impact exhibit from the civil engineer. The box culvert detail is
included on the plan. I think the Old Castle term "split" refers to the fact that the box culvert is two separate
precast pieces. These two pieces get connected when installed on site. Only one box culvert will be
installed. The only area where the stream will be widened has been included in the stream impacts. This
section is located at the inlet of the box culvert. The widening is necessary due to development parameters
dictated by the City of Charlotte. The development of the site is not allowed to cause a rise in the water
surface/flood elevation at the property line during the 100-year storm event. The inlet of the box culvert is only
about 30' from the upstream property line. To achieve the no rise at the property line, the stream had to be
widened to allow for slightly more storage on our project side of the property line.
Thank you,

Good morning Jennifer,
The Division has conducted a review of the above noted application and requires additional information to complete our
401 certification review. Please provide the information requested below within 30 days of this email. The Division will
consider the application to be "on hold" until receipt of a complete response.
1. Your ePCN has a map of the features over the site plan and it states that the "proposed 2' x 10' box culvert detail
can be seen on Sheet C-512". However, this sheet was not included in your application. Can you provide me with
the culvert and retaining wall details.
2. Provide a description that ensures there will be no over widening of the stream. If you can please show in your
culvert/retaining wall details.
Best,
Amie Hoy
