3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
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. The existing
Boathouse and Dock are to replaced with new structures.
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:
none
3d. Explain the purpose of the proposed project:
Remove and replace existing 16'x24' Boathouse Foundaiton. New work to be in accordance with Sheets C1 through
C5.
The boathouse foundation work will be performed "IN THE DRY" using a coffer dam to create a dry work area, or may be
performed "IN THE DRY" during the up coming Lake Draw Down.
Where the work is performed during the upcoming Lake draw -down, temporary Silt Fence and Stone Check Dams shall
be used for erosion control around the work area. All temporary Erosion Control Measures shall be in accordance with
the latest edition of the NC EROSION and SEDIMENT CONTROL PLANNING and DESIGN MANUAL. A minimum of
three (3) rows of temporary Silt Fence shall be provided to separate the work area from the dry Lake Bed. All temporary
Erosion Control Measures shall be removed prior to impoudment refill or at the conclusion of Boathouse Foundation work.
All Trout Buffer disturbance shall be repaired in accordance with the NCDEQ-DLR Trout Buffer and Riparian Area
planting requirements.
See attached Sheet C3 for location of work.

PCN Form — Version 1.3 December 10, 2008 Version

3e. Describe the overall project in detail, including the type of equipment to be used:
New Boathouse Foundation (64 LF of permanent impacts).
New Boathouse Permanent Fill is (64 FT x 10 SF = 630 CF = 24 CY)
BOATHOUSE FOUNDATION. The Boathouse Foundation work shall be performed "IN THE DRY" using a coffer dam to
create a dry work area. Three (3) rows of Turbitidy Curtains shall be used in addition to the Coffer Dam. To comply with
Water Quality requirements, the work 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.
Where the work is performed during the upcoming Lake draw -down, temporary Silt Fence and Stone Check Dams shall
be used for erosion control around the work area. All temporary Erosion Control Measures shall be in accordance with
the latest edition of the NC EROSION and SEDIMENT CONTROL PLANNING and DESIGN MANUAL.
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 Fill (i.e., Boathouse Foundation) 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.
