Describe the overall project in detail, including the type of equipment to be used:
The work proposed herein meets the requirements of work allowed in the above reference NWP, and is necessary to
meet specific requirements of the current State Building Code applicable for this facility. Specifically, the NC Building
Code allows for a maximum occupancy of the existing structures of 347 persons. See the below Table of Building Code
Analysis for Waterfront Facilities. The corresponding waterfront features (i.e., piers, boardwalks, etc.) to support an
occupant load of 347 persons is 1,041 Linear Feet, per Section 3606.8.1 of the 2018 NC Building Code.
SEAWALL (BULKHEAD). The new Seawall (Bulkhead) shall be precast segmental block equal to Toxaway Block, and
shall be placed along the existing shoreline. The Seawall (Bulkhead) shall to be constructed in accordance with Chapter
36 of the 2018 NC Building Code, and in accordance with Sheets C1 through C5.
The 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.
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.

MEANS OF EGRESS
SECTION 1004
OCCUPANT LOAD
-- 1004.1 Design occupant Load. In determining means of
egress requirements, the number of occupants for whom
means of egress facilities are provided shall be determined in
I.
accordance with this section.
1004.1.1 Cumulative occupant. loads* Where the path of
egress travel includes intervening rooms, areas or spaces,,
cumulative occupant loads shall be determine in accor-
dance with this section.
1004.1.1.1 Intervening spaces or accessary- areas.
Where occupants egress from one or more rooms, arias
or spaces through others, the design occupant load
shall be the combined occupant load of interconnected
accessory or intervening spaces. Design of egress path
capacity shall be hosed on the cumulative portion of
occupant loads of all roams, areas or spaces to that
point along the path of egress travel.
1404.1.1.2 Adjacent levels for mezzaniaes. That por-
tion of the occupant load of a mezzanine with required
egress through a room, area or space on an adjacent level
shall be added to the occupant load of that room, area or

UNDER NATIONWIDE PERMIT (NWP) 39. This Nationwide Permit
allows for the discharges of dredged or fill material into
non —tidal waters of the United States for the construction or
expansion of commercial and institutional building foundations
and building pads and attendant features that are necessary for
the use and maintenance of the structures. Attendant features
may include, but are not limited to, roads, parking lots, garages,
yards, utility lines, storm water management facilities,
wastewater treatment facilities, and recreation facilities such as
playgrounds and playing fields. Examples of commercial
developments include retail stores, industrial facilities,
restaurants, business parks, and shopping centers.
1.1 The work proposed herein meets the requirements of
work allowed in the above reference NWP, and is necessary
to meet specific requirements of the current State Building
Code applicable for this facility. Specifically, the NC Building
Code allows for a maximum occupancy of the existing
structures of 347 persons. See the below Table of Building
Code Analysis for Waterfront Facilities. The corresponding
waterfront features (i.e., piers, boardwalks, etc.) to support
an occupant load of 347 persons is 1,041 Linear Feet, per
Section 3606.8.1 of the 2018 NC Building Code.

1.2 The proposed seawall will serve as structural suppose
for the waterfront pier facilities, and will also provide
shoreline stabilization and Lake access.
1.3 The total length of available waterfront is only 600
Linear Feet. Therefore, the Occupancy for the Waterfront
structures (piers, etc.) will be limited by the available
waterfrontage. The maximum Occupancy will be limited to

the outside (wet side) of the coffer dam. The work area
isolated by the coffer dam may 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 dewatering flow from the flirtation bag
shall be discharged in front of (on the work side of) the two
(2) turbidity curtains for additional filtration. 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.

GENERAL NOTES AND SPECIFICATIONS (Continued).
5.0 All work shall be in accordance with the latest edition of
the North Carolina Building Code, ACI 301 — Specifications for
Structural Concrete for Buildings, ACI 318 & 318R — Building
Code Requirements for Structural Concrete, ACI 548.1R Guide
for Use of Polymers in Concrete, ACI 546R Concrete Repair
Guide, AISC Steel Construction Manual, OSHA Safety and
Health requirements, and all other applicable codes,
ordinances, and regulations. Contractor shall obtain all
required permits prior to beginning work
6.0 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.
7.0 Contractor shall verify and establish all Finish Floor
Elevations (FIFE) prior to beginning work. Do not locate any
part of the structure within any set —back, easement,
right—of—way, floodway or flood fringe, NCDEQ regulated
set —back, trout stream buffer zone (or other buffer zone or
set back). Contractor shall obtain all required permits prior to
beginning work. Contractor shall locate all property
boundaries prior to beginning work. Contractor shall locate,
flag and protect all underground utilities prior to beginning
work.
8.0 Design criteria and assumptions:
Design Method = ASCE-7, Minimum Design Loads for Buildings
and other Structures
Soil Bearing Capacity = 2000 psf, assumed
9.0 FOOTINGS. The bottom 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). All individual pier footings shall be restrained
from sliding with anti —slide keys, helical piers, etc).
10.0 CONCRETE. Concrete shall have a minimum compressive
strength of 4000 psi at 28 days and shall have 5 to 7%
entrained air. DO NOT ALLOW FRESH CONCRETE TO CONTACT
LAKE WATERS.
11.0 REINFORCING STEEL. All reinforcing steel and anchor
dowels shall conform to ASTM A 615, Grade 60 and shall
have standard deformations. All footer reinforcing bars shall
have a minimum of 3" of concrete cover. All rebar lap
splices shall be 60 bar diameters unless otherwise noted. All
footer steel shall be bonded and grounded per the NEC.
12.0 TROUT BUFFER REQUIREMENTS. Where the "on shore"
work is within 25—ft of the top —of —bank, and exceeds 10% of
the shoreline frontage, the Contractor shall obtain a Trout
Buffer Variance from the NCDEQ—DLR Asheville Regional Office
(P.O.C. Stan Akin, 828-296-4500).
13.0 15A NCAC 04B .0125 BUFFER ZONE REQUIREMENTS.
(a) Unless otherwise provided, the width of a buffer zone is
measured from the edge of the water to the nearest edge of
the disturbed area, with the 25 percent of the strip nearer
the land —disturbing activity containing natural or artificial
means of confining visible siltation.
(b) The 25 foot minimum width for an undisturbed buffer
zone adjacent to designated trout waters shall be measured
horizontally from the top of the bank.
(c) Where a temporary and minimal disturbance is permitted
as an exception by G.S. 113A-57(1), land —disturbing activities
in the buffer zone adjacent to designated trout waters shall
be limited to a maximum of ten percent of the total length
of the buffer zone within the tract to be distributed such
that there is not more than 100 linear feet of disturbance in
each 1000 linear feet of buffer zone. Larger areas may be
disturbed with the written approval of the Director.
(d) No land —disturbing activity shall be undertaken within a
buffer zone adjacent to designated trout waters that will
cause adverse temperature fluctuations, as set forth in 15A
NCAC 2B .0211 "Fresh Surface Water Classification and
Standards", in these waters.
