Re: Proposed Shoreline Stabilization for Lot 20, Nantahala Highlands, Lake Nantahala
( "Lot 20 ")
Dear Sir or Madam:
On October 5, 2012, my wife (Amy) and I purchased Lot 20 referenced above. We plan
to build a single family residence on the property. Prior to construction of the residence,
and while Lake Nantahala is below normal winter levels for Duke Energy's maintenance
of the spill gates, we propose to engage in shoreline stabilization per the accompanying
application.
The Duke Energy project area adjoining the lot has significant vegetation along its 5+
foot bank, one reason we like Lot 20. However, probably because the land is a rounded
area extending into the lake, there has been significant shoreline erosion over the years.
As shown in the accompanying photographs, along much of the shoreline caves have
been hollowed out by wave action (accompanying pictures A and B are typical). In
addition, there are two areas along the southwestern part of the shoreline where the bank
has collapsed, pulling trees into the water and exposing additional areas of soil to erosion
(see pictures C and D).
Our goal in this proposed shoreline stabilization project is to prevent further erosion
through construction of a dry-stack seawall of large and medium boulders, with addition
of appropriate rip -rap and use of filter fabric. In a small portion of the shoreline, where
there is already some rock supporting the bank (see picture G), the seawall can be
constructed without much disturbance of the bank. In most areas, before the seawall is
FV7�._
constructed in front of the bank, a portion of the bank will need to be cut off in order to
allow access to fill the cave and support the bank above the cave. Where the bank has
already collapsed, vegetation will need to be removed so that the earth can be pushed
"D
back into place.

Our secondary objective in this project is to preserve vegetation where possible (such as
by trimming rhododendron to allow seawall construction but leaving the plant to put out
new growth). We will need to cut several trees that are already unstable; we would
manage such trees in accordance with Duke Energy's Shoreline Management Guidelines
and plan to replace the trees as appropriate. There are smaller trees that would also be
cut, but there are also other small trees that will prosper with the additional exposure to
light. The construction access point will also be the proposed dock location, thus
minimizing disturbance of the bank and vegetation.
Preservation of shoreline vegetation will preserve shade at water's edge for wildlife.
Also, as the project proceeds, we will identify root masses that can be left in the lake to
provide fish habitat.
We believe that the proposed stabilization project is consistent with applicable standards
and would appreciate your prompt review of the applications. If we have overlooked
anything, or if you have additional suggestions or requirements, please do not hesitate to
contact me at 828 - 342 -5133 or kwm .mountaintop&gLnail.com. You may also contact
my contractor, Brett Murphy (no relation) at 828- 421 -1973 or
