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 parcel is wooded and undeveloped and is located in Toxaway Estates, a private residential development in western
Transylvania County, NC. The lot has several un -named tributaries and drain directly into Lake Toxaway which has a
classification of B: Trout. The general land use is residential.
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 accumulated sediment in streams, stabilize banks, install grade control boulder weirs to create step pools to trap
future sediment and improve water quality. The site and streams receive runoff directly from the Toxaway Golf Course.
3e.
Describe the overall project in detail, including the type of equipment to be used:
Remove approximately 50 cubic yards of sediment, construct approximately 130 linear feet of boulder stream bank
stabilization. Install 105 lienar feet for boulder weirs for grade control & step pools. See attached Sheets R -1 & R -2.
The overall length of the proposed stream bank stabilization shall not exceed 130 linear feet. Stabilization structure to be
natural granite boulders, class 2 riprap gradation. The structure for the grade control weirs shall also be natural granite
boulders. Where it is necessary to create a dry work area, 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. Downstream water shall likewise be
monitored with calibrated turbidity meters 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.

5.0 RESTORATION OF TROUT BUFFER AROUND POND
5.1. Prior to beginning work the Owner shall apply for and obtain a trout buffer
waiver from the Director of the Divhlm of Energy. Mineral and land Resources In
the Raleigh Central Office.
5.2 Re— establish and maintain an undisturbed buffer zone 25 feet wide or of
sufficient width to confine visible siltation within the 25% of the buffer zone
nearest the land disturbing activity, whichever Is greater.
Hydrosssd mixtures and wash—waters shall not be allowed to enter streams.
5.3 Additional disturbance of riparian vegetation shall be kept to a minimum.
Where disturbance for temporary come Is necessary, trees and shrubs Mall be
cut and the stumps and roots Mall be left to resprout. Disturbed stream banks
and the widest possible zone outward from the restored stream channel Mall be
planted with native tress and shrubs (1 a, rhododendron, dog hobble, red maple,
silky willow, tog alder, black willor, sleamare). This will help provide long —term
bank stability and stream shading Silky dogwood, anky willow and black willow
kern be planted as live stakes collected during the dormant season. Cuttings
should be randomly planted an four (4) foot centers from the waters edge to the
tap —of —bark. Trees Mould be planted on ten (10) to twelve (12) foot centers.
Stream banks N thane areas shall also be seeded with native need mix with a
temporary nursery crop of wheat, millet, or other grain.
5.4 Provide grosses, trees and shrubs throughout all disturbed trout buffer
zones.
5.5 The Contractor shall provide ant fence and other erosion control measures
as necessary to prevent off site sedimentation and Increased turbidity In surface
waters. Do not allow sediment to enter the creek
5.8 Restore all disturbed trout buffer areas In accordance with the NC DENR
Ecosystem Enhancement Program Publication Guidelines for Riparian Buffer
Restoration, October, 2004.

SEDIMENT REMOVAL PLAN OF ACTION
1.1 Sediment Removal TeMnlque; Remove sediment from stream bed shall be by
hand method (ag.. bucket and shovel). After removal of the sediment, the
stream shall be reemstructed with natural techniques so that Is mimics the
stream channel above the Impacted acne. Only dem, large, angular rock, root
wads. logs, or other natural stream design materials and techniques shall be
used. Materials shall not be placed In the stream channels In a manna that
overly constricts the stream Bow or that Impedes aquatic life movement during
low Bow conditions.
1.2 Trubldity Reduction Techniques;
1.2.1 In —water excavation shall be conducted In dry work areas whenever
practical. The stream @hall be Intercepted immediately upstream fo the Impacted
area and Mall be piped around the work area using we (1) 48" cilametr HOPE
pipe or equal. A minimum of four (4) stone check dens Mall be placed In
series at the Iowa and of the work area to trap my sediment runoff that may
occur during construction. The check dams shall be removed and the stream bed
restored Immediately prior to re— establishing Bow tack to the original stream
section.
1.2.2. Sediment and erosion control measures for sensitive watersheds (15A
NCAC 048 .0124) shall be used and maintained until all disturbed sons are
permanently stabilized. All bare mils shall be seeded as soon as possible after
ground disturbance. Erosion control matting Is Installed with seeding an disturbed
banks.. Matting shall be secured with staples. stakes, or wherever possible, live
stokes of native trees. Tell fescue shall not be used along the stream.
1.2.3 NI heavy equipment operated near streams shall be Inspected and
maintained regularly to prevent contamination of fuels, lubricants. or hydraulic
Builds.
1.3.3. Hydroaeed mixtures and wash—waters shall not be allowed to enter
stream&
3.3 4. Disturbance of riparian vegetation shall be kept to a minimum. Where
disturbance far temporary access Is neeaenery, trees and shrubs shall be cut and
the stumps and roots shall be left to reeprout. Disturbed stream banks and the
widest possible zone outward from the restored stream channel shall be planted
with native trees and shrubs (f.a., rhododendron, dog hobble, red maple, silky
willow, tag alder, black willow, sycamore). This will help provide long —term bank
stability and stream shading. Silky dogwood, silky willow and black willow can be
planted as live stakes collected during the dormant somm. Cuttings should be
randomly planted an four (4) foot centers from the waters edge to the
top —of —bank Treas should be planted an tm (10) to twelve (12) foot centers.
Stream banks In Ness. areas shall also be seeded with native owed mix with a
temporary nursery rap of wheat, millet, or other grain.
4.0 Ttrnellne for Removal Process. Sediment removal shim begin as Boon as
practicable. after all required permits have been obtained. The construction
pMod shall not exceed 14 calendar days. Work shall not be performed between
October 15th and April 15th unless specifically allowed or permitted by the by the
NCDENR or NC Fish k Wildlife.
SEDIMENT REMOVAL FINAL REPORT
At the condu@on of the project, the Project Manager / Contractor shall prepare
and submit a 'Sediment Removal Final Report' to the NCDENR Division of Water
Oudity, Asheville Regional Office, 2090 US Hwy 70 Swonnanca, NC 28778, (POC
Ms. Undo W1ggs. telephone 828 - 298 - 4500). The "Sediment Removal Final
Report' Mall Include;
1.0 Overview of Restoration work
2.0 Post— Removal Assessment
21 Photo Documentation following the Sediment Removal at some locations
previous photo documentation (Also Include a photo documenting the epos area)
22 Other Findings — Vlsud/Survey Work.
23 Conclusions.
DOWNSTREAM MONITORING.
1.0 The Contractor shall survey and document the downstrmom conditions prior
to beginning work The Carbr to shall obtain authorization and right —of —entry
from the downstream property omen prior to beginning this phase of work. Sae
OWO Dometmam Monitoring Requirements. Any off —site sedimentation, Insane
In surface water turbidity above the background level, or other regulatory
Infraction, shall be remedied at the Contractor's expense, All monitoring and
Inspections stall also be In accordance with conditions of the Sedimentation k
Erosion Control Permit; Constructlon Stornwater Permit 1400010000, 401
certification, and stream standards.
2.0 DOWNSTREAM MONITORING (per DWO)
2.1 Before work begins the receiving stream shall be evaluated by the
Contractor. Depending on the downstream reach at least 3 locations shall be
setabllehed for monitoring. Initial rote section. ore to be performed Photo
documentation of those locations Mall also be provided.
2.2 Downstream water shall be mmltered periodically (minimum of weekly) while
work Is being performed. The withdrawal or repair work should be discontinued If
downstream waters are turbid or If sediment Is released. If eedimmt Is released
or turbid waters persists contact DWO within twenty four hours for guidance. If
sediment loss Impacts the receiving stream than sediment removal will be required
under DWO approval.
2.3 Once work Is completed mother cross section and photo documentatim shall
be pa tormed at the set monitoring location& OWO will review this Information to
canton stream knpacts have not occurred.
24 Sediment must be prevented from reaching surface waters during the
lake/pond drawdown. The withdrawal fixture should be placed at or near the
surface with Boats (and water level reduced by no more than me vertical foot
per day. In accordance with Dam Safety Guldellnes).
2.5 While work Is being perform ad at the dam, the lake /pand should be Isolated
from moving water (i.e., via sandbags at the lake /pond headwaters and elphaning
around the lake, or other means necessary to perform work 'In the dry).
however, Bow to the receiving waters should not be removed r reduced to a
level detrimental to aquatic life.
2.8 After the Impoundment Is drained, install sediment and erosion control
structures and/or hydromedhrg as be nacsesory to stabilize exposed soil and
sadIment (r other method of "llizatlon).
2.7. Prior to beginning work the Omer shall attempt to remove fish from the
pond to Imam the Impact of the drawdom on the aquatic life.
