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. There is an existing
seawall (Bulkhead) along the shoreline. A portion of the existing seawall will be removed as necessary to install the new
boathouse foundation.
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:
Construct new 10'x14'-Y Addition to Existing Boathouse Foundation. A local variance/authorization may be required for
the LTCA to encroach into the 15-FT Side Tard Setback. Remove existing timber seawall and replace with a new natural
boulder seawall. Maintenance and repair for existing Docks. New work to be in accordance with Sheets C1 through
C12.
The boathouse foundation work will be performed "IN THE DRY" using a coffer dam to create a dry work area.
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 (84 LF of permanent impacts).
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.

4.0 CAST —IN —PLACE CONCRETE — Concrete shall have a
28 day compressive strength of 4000 psi and shall have
5 to 7% entrained air. No water shall be added to fresh
concrete on site. A super —plasticizer add mixture,
specified by the concrete mix designer, may be added on
site to increase slump; directions shall be printed on
each trip ticket. All trip tickets shall be maintained by

fillers, and ground with which the concrete is to come
into contact shall be free from frost.
4.1.3 Frozen materials or materials containing ice shall
not be used.
4.1.4 The ambient temperature shall be 40 degrees F
and rising before concrete beginning concrete placement.
5. REINFORCING STEEL
5.1 Reinforcing steel shall conform to ASTM A615, grade
60 (fy=60,000 psi) and shall have standard deformations.
All lap splices shall be 60 bar diameters unless otherwise
noted.
5.2 All reinforcing steel shall be accurately and securely
tied and anchored in place to prevent dislocation during
the placement operation.
5.3 Provide corner bars, 48 bar diameters x 48 bar
diameters, at each continuous footing and foundation wall
corner.

reinforcing bars shall have a minimum of 3" of concrete
cover.
5.5 Size & spacing of Vertical Hook Dowels shall match
the Vertical Wall Steel.
6.0 CONTROL JOINTS — Provide control joists in retaining
wall at intervals not exceeding 20 feet.
7.0. STEEL HARDWARE — Steel connectors on exterior
applications shall be hot dipped galvanized or stainless
steel. Steel connectors on interior applications shall be
primed or power coated.
8.0 FOOTERS — All footers shall bear on satisfactory
insitu material. No portions of the foundation shall bear
of fill dirt or fill soil. Contractor shall verify that the site
has stable geotechnical conditions. Top of footings shall
be located below the frost line. Footings shall be
stepped where it is necessary to change the elevation of
the top surface of the footings or where the slope of the
bottom surface of the footings will exceed 0.1 unit
vertical in ten units horizontal (1% slope).
