INSTALLATION SPECIFICATIONS
1. THE BASE OF BOTH END POSTS SHOULD BE AT LEAST ONE FOOT HIGHER THAN THE MIDDLE OF THE
FENCE. CHECK WITH A LEVEL IF NECESSARY,
2. INSTALL POSTS 4 FEET APART IN CRITICAL AREAS AND 6 FEET APART ON STANDARD APPLICATIONS,
3. INSTALL POSTS 2 FEET DEEP ON THE DOWNSTREAM SIDE OF THE SILT FENCE, AND AS CLOSE AS
POSSIBLE TO THE FABRIC, ENABLING POSTS TO SUPPORT THE FABRIC FROM UPSTREAM WATER
PRESSURE.
4. INSTALL POSTS WITH THE NIPPLES FACING AWAY FROM THE SILT FABRIC.
5. ATTACH THE FABRIC TO EACH POST WITH THREE TIES, ALL SPACED WITHIN THE TOP 8 INCHES OF THE
FABRIC, ATTACH EACH TIE DIAGONALLY45 DEGREES THROUGH THE FABRIC, WITH EACH PUNCTURE AT
LEAST 1 INCH VERTICALLY APART. ALSO, EACH TIE SHOULD BE POSITIONED TO HANG ON A POST
NIPPLE WHEN TIGHTENED TO PREVENT SAGGING.
6. WRAP APPROXIMATELY 6 INCHES OF FABRIC AROUND THE END POSTS AND SECURE WITH 3 TIES.
7. NO MORE THAN 24 INCHES OF A 36 INCH FABRIC IS ALLOWED ABOVE THE GROUND LEVEL.
S. THE INSTALLATION SHOULD BE CHECKED AND CORRECTED FOR ANY DEVIATIONS BEFORE COMPACTION.
9, COMPACTION IS VITALLY IMPORTANT FOR EFFECTIVE RESULTS, COMPACT THE SOIL IMMEDIATELY NEXT TO
THE SILT FENCE FABRIC WITH THE FRONT WHEEL OF THE TRACTOR, SKID STEER, OR ROLLER EXERTING
AT LEAST 60 POUNDS PER SQUARE INCH. COMPACT THE UPSTREAM SIDE FIRST, AND THEN EACH SIDE
TWICE FOR A TOTAL OF 4 TRIPS.
MAINTENANCE
INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY REQUIRED
REPAIRS IMMEDIATELY,
SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, TEAR, DEOMPOSE OR BECOME INEFFECTIVE, REPLACE
PROMPTLY.
REMOVE SEDIMENT DEPOSITS AS NECESSARY TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN
AND TO REDUCE PRESSURE ON THE FENCE, TAKE CARE TO AVOID UNDERMINING THE FENCE DURING
CLEANOUT,
REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND BRING THE AREA TO GRADE AND
STABIUZE IT AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY STABILIZED,

3. STEEL POSTS SHOULD BE DRIVEN TO A DEPTH OF 24 INCHES, SPACED A MAXIMUM OF 4 FEET APART, AND INSTALLED UP THE SIDES
OF THE BASIN AS WELL. THE TOP OF THE FABRIC SHOULD BE 6 INCHES HIGHER THAN THE INVERT OF THE SPILLWAY. TOPS OF
BAFFLES SHOULD BE 2 INCHES LOWER THAN THE TOP OF THE BERMS.
4. INSTALL AT LEAST THREE ROWS OF BAFFLES BETWEEN THE INLET AND OUTLET DISCHARGE POINT. BASINS LESS THAN 20 FEET IN
LENGTH MAY USE 2 BAFFLES.
5. WHEN USING POSTS, ADD A SUPPORT WIRE OR ROPE ACROSS THE TOP OF THE MEASURE TO PREVENT SAGGING.
S. WRAP POROUS MATERIAL, LIKE JUTE BACKED BY COIR MATERIAL, OVER A SAWHORSE OR THE TOP WIRE. HAMMER REBAR INTO THE
SAWHORSE LEGS FOR ANCHORING. THE FABRIC SHOULD HAVE FIVE TO TEN PERCENT OPENINGS IN THE WEAVE. ATTACH FABRIC TO
A ROPE AND A SUPPORT STRUCTURE WITH ZIP TIES, WIRE, OR STAPLES.
7. THE BOTTOM AND SIDES OF THE FABRIC SHOULD BE ANCHORED IN A TRENCH OR PINNED WITH 8-INCH EROSION CONTROL MATTING
STAPLES.
B. DO NOT SPUCE THE FABRIC, BUT USE A CONTINUOUS PIECE ACROSS THE BASIN.
INSPECT BAFFLES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY REQUIRED REPAIRS IMMEDIATELY,
BE SURE TO MAINTAIN ACCESS TO THE BAFFLES. SHOULD THE FABRIC OF A BAFFLE COLLAPSE, TEAR, DECOMPOSE, OR BECOME
INEFFECTIVE, REPLACE IT PROMPTLY.
REMOVE SEDIMENT DEPOSITS WHEN IT REACHES HALF FULL TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO
REDUCE PRESSURE ON THE BAFFLES. TAKE CARE TO AVOID DAMAGING THE BAFFLES DURING CLEANOUT, SEDIMENT DEPTH SHOULD
NEVER EXCEED HALF THE DESIGNED STORAGE DEPTH.
AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY STABILIZED, REMOVE ALL BAFFLE MATERIALS AND UNSTABLE SEDIMENT
DEPOSITS, BRING THE AREA TO GRADE. AND STABILIZE IT.

5. ASSEMBLE THE SKIMMER FOLLOWING THE MANUFACTURERS INSTRUCTIONS, OR AS DESIGNED.
6. LAY THE ASSEMBLED SKIMMER ON THE BOTTOM OF THE BASIN WITH THE FLEXIBLE JOINT AT THE INLET OF THE
BARREL PIPE. ATTACH THE FLEXIBLE JOINT TO THE BARREL PIPE AND POSITION THE SKIMMER OVER THE
EXCAVATED PIT OR SUPPORT. BE SURE TO ATTACH A ROPE TO THE SKIMMER AND ANCHOR IT TO THE SIDE OF
THE BASIN, THIS WILL BE USED TO PULL THE SKIMMER TO THE SIDE FOR MAINTENANCE,
7. EARTHEN SPILLWAYS -INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST EXTENT POSSIBLE: THE

ALL THE UNSTABLE SEDIMENT, SMOOTH THE AREA TO BLEND WITH THE ADJOINING AREAS AND STABILIZE
PROPERLY.
MAINTENANCE
INSPECT SKIMMER SEDIMENT BASINS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (ONE-HALF INCH OR GREATER)
RAINFALL EVENT AND REPAIR IMMEDIATELY, REMOVE SEDIMENT AND RESTORE THE BASIN TO ITS ORIGINAL DIMENSIONS
WHEN SEDIMENT ACCUMULATES TO ONE-HALF THE HEIGHT OF THE FIRST BAFFLE. PULL THE SKIMMER TO ONE SIDE
SO THAT THE SEDIMENT UNDERNEATH IT CAN BE EXCAVATED. EXCAVATE THE SEDIMENT FROM THE ENTIRE BASIN, NOT
JUST AROUND THE SKIMMER OR THE FIRST CELL, MAKE SURE VEGETATION GROWING IN THE BOTTOM OF THE BASIN
DOES NOT HOLD DOWN THE SKIMMER,
REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE -ANCHOR THE BAFFLES IF WATER IS FLOWING UNDERNEATH OR
AROUND THEM,
IF THE SKIMMER IS CLOGGED WITH TRASH AND THERE IS WATER IN THE BASIN, USUALLY JERKING ON THE ROPE WILL
AN R STORE FLOW. IF THESE DOES NOT WORK MAKE THE SKIMMER BOB UP AND DOWN AND DISLODGE THE DEBRIS D E
PULL THE SKIMMER OVER TO THE SIDE OF THE BASIN AND REMOVE THE DEBRIS. ALSO CHECK THE ORIFICE INSIDE
THE SKIMMER TO SEE IF IT IS CLOGGED; IF SO REMOVE THE DEBRIS.
IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND THE OBSTRUCTION CLEARED
WITH A PLUMBER'S SNAKE OR BY FLUSHING WITH WATER. BE SURE AND REPLACE THE ORIFICE BEFORE
REPOSITIONING THE SKIMMER. CHECK THE FABRIC LINED SPILLWAY FOR DAMAGE AND MAKE ANY REQUIRED REPAIRS
WITH FABRIC THAT SPANS THE FULL WIDTH OF THE SPILLWAY. CHECK THE EMBANKMENT, SPILLWAYS, AND OUTLET FOR
EROSION DAMAGE, AND INSPECT THE EMBANKMENT FOR PIPING AND SETTLEMENT. MAKE ALL NECESSARY REPAIR
IMMEDIATELY. REMOVE ALL TRASH AND OTHER DEBRIS FROM THE SKIMMER AND POOL AREAS.
FREEZING WEATHER CAN RESULT IN ICE FORMING IN THE BASIN. SOME SPECIAL PRECAUTIONS SHOULD BE TAKEN IN
THE WINTER TO PREVENT THE SKIMMER FROM PLUGGING WITH ICE,

CONSTRUCTION REQUIREMENTS FOR SCOUR HOLES
TO AVOID SHIFTING OF THE SCOUR HOLE AFTER INSTALLATION, THE BMP SHOULD BE INSTALLED IN UNDISTURBED SOIL INSTEAD OF IN FILL MATERIAL.
INSTALL PREFORMED SCOUR HOLES AFTER SITE STABILIZATION.
ENSURE THAT THE APRON IS FLUSH WITH NATURAL GROUND. THE ELEVATION OF THE TOP OF THE PREFORMED SCOUR HOLE SHOULD BE THE SAME AS THE ELEVATION
OF THE PSRM,
ENSURE THAT RIPRAP CONSISTS OF A WELL -GRADED MIXTURE OF STONE. SMALLER -SIZE RIPRAP STONES SHOULD BE USED TO FILL VOIDS BETWEEN LARGER STONES,
WHERE PRACTICAL, ROUTE OFF -SITE RUNOFF AWAY FROM THE BMP.
IMMEDIATELY AFTER CONSTRUCTION, STABILIZE THE EXIT AREAS WITH VEGETATION,
CLEAR THE AREA OF ALL CONSTRUCTION DEBRIS AND CHECK THE EXIT AREAS FOR ANY POTENTIAL OBSTRUCTIONS THAT COULD PROMOTE CHANNELIZED FLOW.

CONSTRUCTION NOTES
1. CONSTRUCTION SEQUENCING SHOULD BE CAREFULLY PLANNED TO
ALLOW PLANTINGS TO BE INSTALLED AND THE WETLANDS
BROUGHT ONLINE WITHIN 14 DAYS AFTER THE COMPLETION OF
GRADING ACTIVITIES.
2.PLANTINGS SHOULD BE WATERED PER NURSERY SPECIFICATIONS
UNTIL THE WETLAND STRUCTURE IS INUNDATED WITH WATER.
3.SHOULD PLANTING BE DELAYED, A TEMPORARY WETLAND SEED
MIX MAY BE PLANTED TO STABALIZE ALL DISTURBED SOILS.
4. iF THE STRUCTURE IS BROUGHT ONLINE PRIOR TO PLANTING, A
PORTABLE PUMP SHOULD BE USED TO PUMP WATER DOWN 3
DAYS PRIOR TO PLANT DELIVERY/INSTALLATION.
5.INLET AND OUTLET DEVICES SHOULD BE PROTECTED FROM
SCOUR THAT MAY OCCUR DURING HEAVY RAIN EVENTS,
6.THE WETLAND SHOULD BE STAKED ACCORDINGLY TO ALLOW FOR
PROPER GRADES AS SHOWN ON THE PLAN.
7.THE OPTIMAL PLANTING PERIOD IS FROM EARLY APRIL THROUGH
MI N PLANTINGS MAY ALSO B INSTALLED IN D JU E. LA. E S LLED EARLY FALL
DEPENDING ON THE VARIETY.
SEEDBED PREPARATION:
CHISEL COMPACTED AREAS AND SPREAD TOPSOIL 3" DEEP OVER
ADVERSE SOIL CONDITIONS, IF AVAILABLE,
RIP ENTIRE AREA 6" DEEP.
REMOVE ALL LOOSE ROCK, ROOTS, AND OTHER OBSTRUCTIONS
LEAVING SURFACE REASONABLY SMOOTH AND UNIFORM,
APPLY AGRICULTURAL LIME AND FERTILIZER UNIFORMLY AND MIX
WITH SOIL.
CONTINUE TILLAGE UNTIL A WELL PULVERIZED, REASONABLY UNIFORM
SEEDBED IS PREPARED 4" TO 6" DEEP,
SPREAD SEED ON FRESHLY PREPARED SEEDBED AND COVER LIGHTLY
