application:
This home site located in Toxaway Estates, a private residential development in western Transylvania County, NC. The
lot borders Lake Toxaway which has a classification of B: Trout. The general land use is residential. There is an existing
stone and mortar seawall along the shoreline. The existing seawall is deteriorated and required repair and/or
replacement.
3b.
List the total estimated acreage of all existing wetlands on the property:
none
3c.
List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:

Explain the purpose of the proposed project:
Construct new 32'x38' Boathouse Foundation & Retaining Wall Structure meeting side yard setback rules. Construct new
segment of Seawall to tie-in Boathouse Foundation to existing boulder seawall. New work to be in accordance with
Sheets C1 through C8.
The boathouse foundation work will be performed "IN THE DRY" using a coffer dam to create a dry work area.
The seawall replacement work will be performed "IN THE WET" using trbitidy curtains to isolate the work area from the
Lake waters.
No disturbance within existing Vegetated Trout Buffer.
See attached Sheet C3 for location of work.

Describe the overall project in detail, including the type of equipment to be used:
New Boathouse Foundation (102 LF impact) and new tie-in Seawall (12 LF impact) in accordance with attached Sheets
Sheet C1 through C8.
BOATHOUSE FOUNDATION. The boathouse foundation work shall be performed "IN THE DRY" using a coffer dam to
create a dry work area. To comply with Water Quality requirements, the will be performed in the dry. Where a coffer dam
is used, the work area will be dewatered by pumping. All dewatering discharge shall have a turbidity of not more than 10
NTUs above background or as otherwise specified in DWQ's Turbidity Standards (15A NCAC 02B.0211(3.)(k.)). To
satisfy the required turbidity limit, the dewatering pump discharge shall be filtered through a Bag Filtration Unit equal to
Model BF -400 from Rain -for -Rent with a 100 to 1 micron nominal rating (P.O.C. at Rain -for -Rent is Jeremy at 704-393-
3345). The turbidity level of all discharge shall be monitored with calibrated turbidity meters and the filtration equipment
shall be adjusted as necessary to insure compliance with Water Quality Standards. The water around the dredging areas
shall likewise be monitored with calibrated turbidity meters and the turbidity curtains shall be adjusted as necessary to
insure compliance with Water Quality Standards.
SEAWALL REPLACEMENT. The seawall replacement shall be performed "IN THE WET" using turbidity curtains to
isolated the work area for the Lake waters.
Uncured concrete shall not be allowed to come into direct contact with surface waters. This will be accomplished by
establishing a "dry work area" as described above. "High Early" cementious material shall be in the stone work to
minimize curing time.
Water Quality around the work areas shall be monitored with calibrated turbidity meters. The coffer dams and turbidity
curtains shall be adjusted as necessary to insure compliance with Water Quality Standards. Furnish and install multiple
layers of turbidity curtains as necessary to insure regulatory compliance.
Permanent Toe Apron shall not exceed 25 cubic yards meeting the following requirements;
(a) The quantity of discharged material and the volume of area excavated do not exceed 25 cubic yards below the plane
of the ordinary high water mark or the high tide line;
(b) The discharge will not cause the loss of more than 1/10 -acre of waters of the United States; and
(c) The discharge is not placed for the purpose of a stream diversion.
No disturbance within existing Vegetated Trout Buffer. Provide Turbidity Curtains around work area to maintian water
quality.
See attached Sheet C3 for location of work.
Water Quality around the work areas shall be monitored with calibrated turbidity meters. The coffer dams and turbidity
curtains shall be adjusted as necessary to insure compliance with Water Quality Standards.

The existing Boulder Seawall is to remain. Do not disturb existing seawall. DO NOT CONSTRUCT NEW SITE
RETAINING WALL WITHIN TROUT BUFFER or within the Foundation -Zone -of -Influence such as to cause additional
surcharge on the existing boulder seawall. DO NOT IMPOSE ANY ADDITIONAL SURCHARGE BEHIND THE
