Dear DWQ:
Enclosed, please find five (5) copies of the 401/404 application (PCN Form). A
check for the application review fee is also enclosed. This work is to remove and replace
an existing Boathouse with a new larger Boathouse structure. This work will require the
new Boathouse foundation to extend 12 -FT into the waters of Lake Toxaway in order to
maintain the required 50 -Ft setback from the existing on-site wastewater system. The 12 -
Ft foundation extension will be a permanent fill. This will require special approvals and
a variance from LTCA and the POA. The work will be performed in -the -dry using a
coffer dam to create a dry work area. Lake Toxaway has a water quality classification of
B; Tr.
All disturbed areas not to be filled or flooded will be vegetated pursuant to the
seeding schedule in the Erosion and Sediment Control Planning and Design Manual. If
you have any questions or require any additional information, please do not hesitate to
contact me at [phone] or email tealleneng c eitcom.net.

the existing boathouse structure and foundation.
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:
NEW WORK - REMOVE & REPLACE EXISTING BOATHOUSE - LOCAL VARIANCE REQUIRED;
This Project is to remove the existing 14'x18' Boathouse and replace with a new 28'x30' Boathouse as described herein.
The Foundation for the Boatslip portion of the new Boathouse shall Toxaway Block Precast Concrete Segmental Blocks
with out -to -out dimensions of 14'x30'. The Foundation for the Kayak Storage portion of the new Boathouse shall be a
cast -in-place concrete retaining wall. The work will also include a 12'x14' new wooden Dock. The Architectural features
of the new Boathouse shall comply with the 2016 edition of the Lake Toxaway Community Association Architectural
Review Standards. The existing property lines and the Side Yard Setback shall be located, marked and flagged by a
Professional Land Surveyor prior to beginning work. Verify actual setback requirement with the most current Lake
Toxaway Community Association Architectural Review Standards. Perform incidental excavation as necessary to install
the new Boathouse Foundation. Work to be performed using hand labor & small equipment.
All work shall be performed "IN -THE -DRY" . This will be accomplished by installing a temporary coffer dam around the
proposed work area, or by scheduling the work during a lake draw down. 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. 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 installed in addition to the coffer dam as needed to insure compliance with Water Quality Standards.
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.
DOCK PILINGS INSTALLED IN WATER - Pilings may be placed by auger, jetting or drop hammer. Pilings shall receive
a final set by drop hammer or other approved method, acceptable to the Building Inspector to ensure compaction of
material at end bearing. The tip -elevation for all pilings shall be field determined during installation. All pilings shall bear
on satisfactory insitu material having a minimum bearing capacity of 3000 PSF. The minimum embedment depth shall
not be less than 6 -Feet. The actual embedment depth shall be as required to insure pilings bear on satisfactory insitu
material having a minimum bearing capacity of 3000 PSF. All building materials shall be suitable of exterior use.
All Pilings for the Boat Dock that are to be located in -water shall be pressure treated for fresh water immersion.
PERMANENT CONCRETE FILL PLACED IN LAKE TOXAWAY - Due to the close proximity for the existing on-site
wasterwater system, a portion of the Boathouse Foundation will extend 12 -FT into the waters of Lake Toxaway. This is
necessary to maintain 50 -FT minimum setback from surface water (wet slip) to the existing on-site wastewater system.
This will result in 196 CF (7.5 CY) of concrete foundation extending beyond the shoreline of Lake Loxaway. The total
Boathouse Foundation below the normal pool elevation of Lake Toxaway will be 725 CF (27 CY).
VARIANCE, SPECIAL AUTHORIZATION and 401 / 404 PERMITTING ARE REQUIRED. The proposed new Boathouse
is to extend 12 -FT into Lake Toxaway and will be located within the side yard setback and immediately adjacent to the
side property line. This is necessary to maintain a 50 -FT setback from the existing on-site wastewater system. Prior to
beginning construction or ordering materials, the Owner and/or the Contractor shall obtain a Variance and Special
Approval from the Lake Toxaway Community Association and from the POA for the Boathouse to extend beyond the
shoreline into Lake Toxaway, and for the Boathouse to be located within the side yard setback. A Written Authorization -
for -Construction and a Release -of -Claims shall also be obtained from the adjacent property Owners prior to beginning
work. The Authorization -for -Construction and the Release -of -Claims shall be prepared by an NC licensed Attorney
experieneced in environmental and real estate law. No work shall begin without these written Authorizations and
Release -of -Claims. A 401 Water Quality Permit from the NCDEQ-DWR and 404 US Army Corps of Engineers Permit are
also required. No portion of the new structure shall extend beyond any adjacent property line. SEE ATTACHED
DRAWINGS C-3 AND C-4.

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

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.
5.4 Provide 2" clearance for all wall steel. All footer
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 25 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).

maintain a 50—FT setback from the existing on—site
wastewater system. Prior to beginning construction or
ordering materials, the Owner and/or the Contractor shall
obtain a Variance and Special Approval from the Lake
