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.

time should, in fact, additional information become available.
2.2 Limitation of Liability. All other work that may be
required, but not shown herein, shall be designed by the
Contractor. By accepting this engineering document, the
Owner, Contractor and any others to whom it is distributed,
agree to a strict limitation of liability for TERRY E. ALLEN
ENGINEER, Terry E. Allen PE, T.E. ALLEN ENGINEERING, P.C.,
and its employees to an amount not to exceed $25,000.00
or one—half the total amount of paid invoices, whichever is
less.
2.3 Indemnification. The Owner and the Contractor shall
indemnify and hold harmless T.E. Allen Engineering, PC
(hereinafter the `Engineer), and its officers, agents,
employees and assigns, to the fullest extent permitted by
law, for any loss, cost expenses or damages incurred by the
Engineer as a result of the Owner's and/or Contractor's
breach of this Agreement or for any act or omission caused
solely by the negligence of the Owner and/or Contractor, its
employees and its other consultants and subcontractors.
This requirement to indemnify and hold harmless shall
include compensation for the Engineer's reasonable
attorneys fees.
3.0 All work shall be in accordance with 2018 North Carolina
State Residential Building Code, OSHA Safety and Health
Requirements, US Army Corps of Engineers 404 permit
requirements, NCDEQ Division of Water Quality 401 permit
requirements, NC Sedimentation Pollution Control Act, Lake

applicable codes, ordinances, and regulations. The Contractor
shall coordinate all work with the Lake Toxaway Operations
Manager, 16801 Rosman Hwy, Lake Toxaway, NC 28747.
4.0 TURBIDITY CONTROL. The Contractor shall not violate
water quality stream standards during the performance of this
work. The Turbidity Level in the lake waters shall not exceed
10 NTUs above background levels at any time during
performance of this work pursuant to 15A NCAC 02B.0211
(3)(k). The Contractor shall employ any and all methods
necessary to prevent a violation of the Turbidity Standards.
As a minimum, the following turbidity control measures shall
be employed. These methods shall be modified and improved
as necessary to prevent violation of water quality standards;
4.1 To ensure compliance with Water Quality requirements,
the work shall be performed "IN THE DRY" using a coffer dam
to create a dry work area. In addition to the coffer dam, a
minimum of three (3) turbidity curtains shall be used around
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.
