Dear Mrs. Karoly;

Please consider the following responses to the comment letter for the above referenced
project dated February 22, 2007:
1. The interior of this property is cut off from Fibber Magee Drive by the branch that is
indicated on the enclosed overall site layout. In order to access the greater portion of this
property the branch would have to be crossed. Abridge across the stream would be
much more costly that placing a culvert in the stream, so the option of placing a culvert
was chosen. Also, the entrance to the subdivision was designed to only cross the stream
once instead of having two entrances that would essentially circle the pond located near
Fibber Magee Drive. We feel that this design for the entrance minimizes the impacts to
this stream.
2. A detailed site plan is included with this submittal. This plan shows the total project in
relation to surrounding properties, the number of proposed lots and their size, the existing
topography, and the existing streams and the pond.
3. The overall project involves creating a 62-lot subdivision on the 124 acre tract. In
order to access these lots, the project proposes to construct approximately 8,000 linear
feet of streets. As indicated on the overall site plan, the proposed lots for this subdivision
range in size from 1 acre to 3.89 acres. The subdivision is not designed to maximize the
property to achieve the maximum number of lots possible. It is designed using larger lots
in order to retain as much of the property in an unaltered condition as is possible. No
building sites are proposed under this plan. The location of the homes will be decided by
the property owners and the owners of the subdivision at a later date. Streams and ponds
are shown on the site plan. This plan does not propose to disturb any wetlands on the site
so a delineation of wetlands was not performed. The land uses of the surrounding
properties are woodlands, pasturelands and residential homesites.

4. Stormwater for the entire development will be managed by conveying the runoff from
the disturbed areas through grass-lined channels into storm drainage pipes. These grass-
lined channels will serve as drainage through vegetated areas through the life of the
project, and will help to keep the development in a more natural state than if these
channels were to be hard armored with rip rap or concrete. These pipes are proposed to
be placed at very frequent intervals in order to minimize the concentration of stormwater.
Each pipe is proposed to be fitted with a rip rap plunge pool, placed at the discharge end,
in order to help dissipate stormwater energy and to prevent scouring for the life of the
project.
Please consider these responses to the comment letter. We have made an effort to design
this subdivision in such a way as to minimize the impact on the environment and to
protect the natural attributes of the area. Please feel free to call me at (828)-433-5661
with any questions or comments.
Also, it would be greatly appreciated if you could comment on the confusion we have
over the subject of Nationwide 39 Permits and 401 Certification. We have been advised
that if the 404 permit is a Nationwide 39, then 401 Certification is issued as a part of the
404 permit issued by the Army Corps, and written authorization from DWQ is not
required. Is this the case? Your input on this subject would be greatly appreciated.
Sincerely,
WEST CONSULTANTS, PLLC
