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
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 approximately 275 +/- linear feet of existing Seawall. New Seawall to be in accordance with Sheet
C1 through C5. All work shall be performed "IN THE DRY' using a coffer dam to create a dry work area. Trbitidy
curtains to be used around work area to prevent turbidity.
Repair Existing Seawall (85 LF +/-) using like kind materials. Hand work only. Furnish and install Turbidity Curtains
around work area to maintain Water Quality. No disturbance within existing Vegetated Trout Buffer.
See attached Sheet C5 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 Remove and Replace approximately 275 +/- linear feet of existing Seawall. New Seawall to be in accordance with
Sheet C1 through C5. All work shall be performed "IN THE DRY" using a coffer dam to create a dry work area.
Permanent Toe Apron 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.
2.0 Repair Existing Seawall (85 LF +/-) using like kind materials. Hand work only. No disturbance within existing
Vegetated Trout Buffer. Provide Turbidity Curtains around work area to maintian water quality.
See attached Sheet C5 for location of work.
To comply with Water Quality requirements, the Seawall Replacement work will 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 the
upcoming 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 (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.
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.
