five feet from the toe of stockpile.
3. Provide stable stone access point when feasible.
4. Stabilize stockpile within the timeframes provided on this sheet and in accordance
with the approved plan and any additional requirements. Soil stabilization is defined
as vegetative, physical or chemical coverage techniques that will restrain accelerated

overflow events. Replace the tarp, sand bags or other temporary structural
components when no longer functional. When utilizing alternative or proprietary
products, follow manufacturer's instructions.

THE OVERLAPPING PIECE IS IN THE SAME DIRECTION AND AS THE STREAM FLOW AS SHOWN IN THE DETAIL.
ADDITIONAL STAKING SHALL BE APPLIED BY THE CONTRACTOR AT NO ADDITIONAL COST IF THE MATTING SEPARATES
FROM THE SOIL MORE THAN ONE INCH UNDER A REASONABLE PULL.
5. EROSION CONTROL MATTING SHALL BE MADE OF 100% NATURAL FIBERS AND MATERIALS AND BE BIODEGRADABLE
UNDER NORMAL CLIMATE CONDITIONS. EROSION CONTROL MATTING CONTAINING PLASTICS OR PLASTIC BASED

UPSLOPE OF THE BARRIER.
6. PLACE 12 INCHES OF FABRIC ALONG THE BOTTOM AND SIDE OF THE TRENCH.
7. BACKFILL THE TRENCH WITH SOIL PLACED OVER THE FILTER FABRIC AND COMPACT. THOROUGH COMPACTION OF THE
BACKFILL IS CRITICAL TO SILT FENCE PERFORMANCE.
8. DO NOT ATTACH FILTER FABRIC TO EXISTING TREES.
9. CONSTRUCTION SITE RUNOFF SHALL NOT RUN PARALLEL WITH THE FENCE.
10. END OF SILT FENCE NEEDS TO BE TURNED UPHILL.

GENERAL RE -VEGETATION NOTES
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 LANDOWNER, ENGINEER AND PLANTING CONTRACTOR PRIOR TO THE
PROCUREMENT OF PLANT/SEED STOCK.
2. ANY INVASIVE SPECIES VEGETATION WITHIN THE IMMEDIATE WORK AREA, SUCH AS
CHINESE PRIVET (LIGUSTRUM SINENSE) AND MULTIFLORA ROSE (ROSA MULTIFLORA) SHALL
BE REMOVED BY PHYSICAL AND MECHANICAL METHODS PRIOR TO INSTALLATION OF
NATIVE STREAMBANK AND BUFFER SPECIES.
3. 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.
4. ALL DISTURBED AREAS SHALL BE STABILIZED USING TEMPRORY AND PERMANENT SEEDING
AS DEFINED IN THE SEEDING SCHEDULE AND THE APPROVED E&SC PLANS.
5. SUPPLEMENTAL PLANTING ACTIVITIES MAY BE REQUIRED WITHIN THE CONSERVATION
EASEMENT.

NOTES
1. PLANTS SHALL HAVE BEEN GROWN IN A CONTAINER LONG ENOUGH FOR THE
ROOT SYSTEM TO HAVE DEVELOPED SUFFICIENTLY TO HOLD ITS SOIL TOGETHER
ONCE REMOVED FROM THE CONTAINER.
2. PLANTS WILL NEED TO BE WATERED REGULARLY AND PLACED IN SHADY
CONDITIONS UNTIL PLANTING OCCURS.
3. THE DIAMETER OF THE PLANTING PITS FOR EACH PLANT SHOULD BE AT LEAST
TWO TIMES THE DIAMETER OF THE ROOT MASS. SCARIFY THE PLANTING PIT
PRIOR TO EACH PLANT INSTALLATION.
4. SET PLANTS UPRIGHT IN THE CENTER OF THE PIT. THE BOTTOM OF THE ROOT
MASS SHOULD BE RESTING ON UNDISTURBED SOIL.
5. PLACE BACKFILL AROUND BASE AND SIDES OF ROOT MASS, AND WORK EACH
LAYER TO SETTLE BACKFILL AND TO ELIMINATE VOIDS AND AIR POCKETS. WHEN
PIT IS APPROXIMATELY 3 FULL, WATER THOROUGHLY BEFORE PLACING
REMAINDER OF THE BACKFILL. WATER AGAIN AFTER PLACING FINAL LAYER OF
BACKFILL.

LIVE STAKE
1. LIVE STAKES MUST BE DORMANT WHEN CUT. KEEP LIVE STAKES MOIST UNTIL PLANTING. THE STAKE SHOULD BE PREPARED
WITH THE BUDS POINTED UP, AND THE BOTTOM SHOULD BE CUT AT AN ANGLE FOR INSERTION INTO THE GROUND. AN IRON
BAR CAN BE USED TO MAKE A PILOT HOLE TO PREVENT BARK FROM BEING DAMAGED DURING INSTALLATION.
2. LIVE STAKES SHALL BE 0.5" - 2" IN DIAMETER AND 2' - 3' IN LENGTH.
3. LIVE STAKES SHOULD BE PLACED WITH 3 TO a OF THE LENGTH OF THE STAKE BELOW GROUND AND ANGLED DOWNSTREAM.
ENSURE THE BASE OF THE LIVE STAKE WILL REACH THE WATER TABLE. AFTER INSTALLATION THE TOP OF THE LIVE STAKE SHALL
BE PRUNED WITH A SQUARE CUT LEAVING NO LESS THAN 3" AND NO LESS THAN 6" ABOVE THE GROUND.
4. PLANT LIVE STAKES AND HERBACEOUS PLUGS IN OFFSET ROWS AND SPACINGS PER PLANTING PLAN.
