ACCOUNT FOR ALL TYPES OF DEBRIS/GARBAGE
EXPECTED TO BE ENCOUNTERED DURING OPERATIONS.
2. CONTRACTOR SHALL NOT INCREASE CAPACITY OF THE
CHANNEL BEYOND THE PRE -DISASTER CAPACITY AS
DOCUMENTED. UPROOTED STUMPS MAY BE PULLED
FROM THE GROUND (MP EXCAVATION), BUT SHALL
INCLUDE NO MORE THAN MINIMAL AMOUNTS OF SOIL
ATTACHED TO ROOTS. THE DEBRIS REMOVAL WILL BE
RESTRICTED TO THAT ASSOCIATED WITH IDENTIFIED
STORM EVENTS ONLY.
3. DEBRIS SHALL BE DISPOSED ON HIGH GROUND OUTSIDE
OF THE FEMA 100-YR FLOODPLAIN. ANY DEBRIS
REMOVAL, BURNING, AND DISPOSAL OF MAN-MADE
DEBRIS/GARBAGE SHALL ADHERE TO ANY LOCAL OR
STATE REGULATIONS. OFF -SITE DISPOSAL OF DEBRIS
MAY BE REQUIRED; CHECK WITH REGULATORY &
PERMITTING AGENCIES.
4. DEBRIS THAT IS NOT OBSTRUCTING FLOW MAY BE LEFT
FOR HABITAT DEVELOPMENT AND/OR IMPROVEMENT
PER GUIDANCE FROM THE ENGINEER OR SPONSOR.
5. HAZARD LEANING TREES (GREATER THAN 45-DEGREES
SHALL BE CUT AT THE STUMP AND REMOVED. EXISTING
ROOT STRUCTURE AND STUMPS FIRMLY WITHIN THE
SOIL SHOULD REMAIN TO HELP STABILIZE THE SOIL AND
FACILITATE RESPROUTING OF WOODY VEGETATION.
6. EQUIPMENT USED WILL GENERALLY INCLUDE
HYDRAULIC EXCAVATORS EQUIPPED WITH MECHANICAL
THUMB OR GRAPPLE ATTACHMENT, LOADERS, WINCHES
MOUNTED ON TRACKED OR RUBBER -TIRE EQUIPMENT,

Construction:
1. Clear the entrance and exit area of all vegetation, roots, and other objectionable
material and properly grade it.
2. Place the gravel to the specific grade and dimensions shown on the plans, and
smooth it.
3. Provide drainage to carry water to a sediment trap or other suitable outlet.
4. Use geotextile fabrics in order to improve stability of the foundation in locations
subject to seepage or high water table.
Stalk3'-5' inte
Maintenance:
1. Per NCG-01 inspect at least once a week and after each 1 inch or greater rainfall;
make any required repairs immediately.
2. Maintain the gravel pad in a condition to prevent mud or sediment from leaving the
construction site. This may require periodic topdressing with 2 inch stone.
3. Immediately remove all objectionable materials spilled, washed or tracked onto public
roadways.

Construction:
1. Construct the sediment barrier of standard strength or extra strength synthetic filter fabrics.
2. Ensure that the height of the sediment fence does not exceed 24 inches above the ground. (Higher fences may
impound volumes of water sufficient to cause failure of the structure)
3. Construct the filter fabric from a continuous roll cut to the length of the barrier to avoid joints. When joints are
necessary, securely fasten the filter cloth only at a support post with 4 feet minimum overlap to the next post.
4. Support standard strength filter fabric by wire mesh fastened securely to the upslope side of the posts. Extend the
wire mesh support to the bottom of the trench. Fasten the wire reinforcement, then fabric on the upslope side of the
fence post. Wire or plastic zip ties should have a minimum 50 pound tensile strength.
5. When a wire mesh support fence is used, space posts a maximum of 8 feet apart. Supports should be driven securely
into the ground a minimum of 24 inches.
6. Extra strength filter fabric with 6 foot post spacing does not require a wire mesh support fence. Securely fasten the
g p p g q pp Y
filter fabric directly to posts. Wire or plastic zip ties should have a minimum of 50 pound tensile strength.
7. Excavate the trench approximately 4 inches wide and 8 inches deep along the proposed line of the posts and upslope
from the barrier.
8. Place 12 inches of fabric along the bottom and side of the trench.
9. Backfill the trench with soil placed over the filter fabric and compact. Thorough compaction of the backfill is critical to
silt fence performance.
10. Do not attach filter fabric to existing trees.

Maintenance:
1. Inspect sediment fences at least once a week and after each 1
inch or greater rainfall. Make any required repairs immediately.
2. Should the fabric of a sediment fence collapse, tear,
decompose, or become ineffective, replace it promptly.
3. Remove sediment deposits as necessary to provide adequate
storage volume for the next rain and reduce pressure on the
g
fence. Take care to avoid undermining the fence during
cleanouts.
4. Remove all fencing materials and unstable sediment deposits
and bring the area to grade and stabilize it after the contributing
drainage area has been properly stabilized.

1. FINAL VEGETATION SPECIES SELECTION MAY CHANGE
DUE TO REFINEMENT OR SPECIES AVAILABILITY AT THE
TIME OF PLANTING. SPECIES SUBSTITUTIONS WILL BE
COORDINATED BETWEEN THE BANK MANAGER,
ENGINEER AND PLANTING CONTRACTOR PRIOR TO THE
PROCUREMENT OF PLANT/SEED STOCK.
2. LARGER NATIVE TREE SPECIES TO BE PRESERVED WILL
BE FLAGGED BY THE ENGINEER PRIOR TO
CONSTRUCTION ACTIVITIES. ANY TREES HARVESTED FOR
WOODY MATERIAL WILL BE UTILIZED TO PROVIDE BED
AND BANK STABILIZATION AND COVER OR NESTING
HABITAT ON THE FLOODPLAIN. ANY EXCESS WOODY
MATERIALS MAY USED TO BACKFILL OLD CHANNELS.
3. ALL DISTURBED AREAS WILL BE STABILIZED USING
TEMPRORY AND PERMERMANET SEEDING AS DEFINED IN
THE SEEDING SCHEDULE AND THE APPROVED E&SC
PLANS.
