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. 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:
none
3d.
Explain the purpose of the proposed project:
Remove and replace 142 +1- LF of existing masonry stone seawall with a new precast segmental block seawall with
riprap toe apron. Construct new 20'x30' Boathouse. New work to be in accordance with Sheets C1 through C6.
The 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.
Page 4 of 13
PCN Form — Version 1.3 December 10, 2008 Version

3e. Describe the overall project in detail, including the type of equipment to be used:
1.0 REPLACE SEAWALL. Remove and Replace approximately 142 +/- linear feet of existing Seawall. New Seawall to
be in accordance with Sheet C1 through C6. All work shall be performed "IN THE DRY" using a coffer dam to create a
dry work area, or during the Lake Draw Down Period.
2.0 NEW BOATHOUSE. Construct New 20'x30' Boathouse using precast concrete sgmental block (Toxaway Block)
Foundation.
3.0 DRY WORK AREA. All work shall be performed "IN THE DRY" using one of the followin methods:
3.1 COFFER DAM METHOD - WHERE WORK IS PERFORMED AT FULL POOL. 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 work 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.
3.2 WHERE WORK IS PERFORMED DURING THE LAKE DRAW -DOWN PERIOD. 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, whichever comes first.
4.0 All Trout Buffer disturbance shall be repaired in accordance with the NCDEQ-DLR Trout Buffer and Riparian Area
planting requirements.
5.0 Permanent Fill 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.
6.0 See attached Sheet C-35 for location of work.
7.0 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.
8.0 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.
9.0 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.
