<br />SILT FENCE INSTAI I ATION NOTES
<br />S
<br />1. SILT FENCE MUST BE PLACED AWAY FROM THE TOE OF THE SLOPE TO ALLOW FOR WATER
<br />PONDING. SILT FENCE AT THE TOE OF A SLOPE SHOULD. BE INSTALLED IN A FLAT LOCATION
<br />AT LEAST SEVERAL FEET (2-5 FT) FROM THE TOE OF THE SLOPE TO ALLOW ROOM FOR
<br />PONDING AND DEPOSITION,
<br />2. A UNIFORM 6" X
<br />4' ANCHOR TRENCH SHALL BE EXCAVATED USING TRENCHER OR SILT
<br />FENCE INSTALLATION DEVICE. NO ROAD GRADERS, BACKHOES, OR SIMILAR EQUIPMENT SHALL
<br />BE USED.
<br />3. COMPACT ANCHOR TRENCHY
<br />8 HAND WITH A "JUMPING BY W JACK" ft
<br />A 0 HEEL ROLLING.
<br />COMPACTION SHALL BE SUCH THAT SILT FENCE RESISTS BEING PULLED OUT OF ANCHOR
<br />TRENCH BY HAND,
<br />4. SILT FENCE SHALL BE PULLED TIGHT AS IT IS ANCHORED TO THE STAKES. THERE SHOULD
<br />BE NO NOTICEABLE SAG BETWEEN STAKES AFTER IT HAS BEEN ANCHORED TO THE STAKES,
<br />5. SILT FENCE FABRIC SHALL BE ANCHORED TO THE STAKES USING 1 HEAVY DUTY STAPLES
<br />OR NAILS WITH I" HEADS. STAPLES AND NAILS SHOULD BE PLACED 3" ALONG THE FABRIC
<br />DOWN THE STAKE,
<br />6, AT THE END OF A RUN OF SILT FENCE ALONG A CONTOUR, THE SILT FENCE SHOULD BE
<br />TURNED PERPENDICULAR TO THE CONTOUR TO CREATE A "J -HOOK." THE "J -HOOK"
<br />EXTENDING PERPENDICULAR TO THE CONTOUR SHOULD BE OF SUFFICIENT LENGTH TO KEEP
<br />RUNOFF FROM FLOWING AROUND THE END OF THE SILT FENCE (TYPICALLY 10' - 20").
<br />7. SILT FENCE SHALL BE INSTALLED PRIOR TO ANY LAND DISTURBING ACTIVITIES.
<br />SILT FENCE MAINTENANCE NOTES
<br />1. INSPECT BMPs EACH WORKDAY, AND MAINTAIN THEM IN EFFECTIVE OPERATING CONDITION.
<br />MAINTENANCE OF BMPs SHOULD BE PROACTIVE, NOT REACTIVE. INSPECT BMPs AS SOON AS
<br />POSSIBLE (AND ALWAYS WITHIN 24 HOURS). FOLLOWING A STORM THAT CAUSES SURFACE
<br />EROSION, AND PERFORM NECESSARY MAINTENANCE.
<br />2. FREQUENT OBSERVATIONS AND MAINTENANCE ARE NECESSARY TO MAINTAIN BMPs IN
<br />EFFECTIVE OPERATING CONDITION.: INSPECTIONS AND CORRECTIVE MEASURES SHOULD BE
<br />DOCUMENTED THOROUGHLY,
<br />3. WHERE BMPs HAVE FAILED, REPAIR OR REPLACEMENT SHOULD BE INITIATED UPON
<br />DISCOVERY OF THE FAILURE.
<br />4. SEDIMENT ACCUMULATED UPSTREAM OF THE SILT .FENCE SHALL BE REMOVED AS NEEDED
<br />TO MAINTAIN THE FUNCTIONALITY OF THE BMP, TYPICALLY WHEN DEPTH OF ACCUMULATED
<br />SEDIMENTS IS APPROXIMATELY 6".
<br />5. REPAIR OR REPLACE SILT FENCE WHEN THERE ARE SIGNS OF WEAR, SUCH AS SAGGING,
<br />TEARING, OR COLLAPSE.
<br />6. SILT FENCE IS TO REMAIN IN PLACE UNTIL THE UPSTREAM DISTURBED AREA IS STABILIZED
<br />AND APPROVED BY THE LOCAL JURISDICTION, OR IS REPLACED BY AN EQUIVALENT PERIMETER
<br />SEDIMENT CONTROL BMP,
<br />7. WHEN SILT FENCE IS REMOVED, ALL DISTURBED AREAS SHALL BE COVERED WITH TOPSOIL,
<br />SEEDED AND MULCHED OR OTHERWISE STABILIZED AS APPROVED BY LOCAL JURISDICTION.
