AND STABILIZE.
MAINTENANCE
1. INSPECT THE SILT FENCE PERIODICALLY AND AFTER EACH STORM EVENT.
2. IF FENCE FABRIC TEARS, STARTS TO DECOMPOSE, OR IN ANY WAY BECOMES INEFFECTIVE, REPLACE THE AFFECTED
PORTION IMMEDIATELY.
3. REMOVE DEPOSITED SEDIMENT WHEN IT REACHES HALF THE HEIGHT OF THE FENCE AT ITS LOWEST POINT OR IS
CAUSING THE FABRIC TO BULGE.
4. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING CLEAN OUT.
5. AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN STABILIZED, REMOVE THE FENCE AND SEDIMENT DEPOSITS, BRING
THE DISTURBED AREA TO GRADE, AND STABILIZE.

MAINTENANCE
1. INSPECT ENTRANCE PAD AND SEDIMENT DISPOSAL AREA WEEKLY AND AFTER STORM EVENTS OR HEAVY USE.
2. RESHAPE PAD AS NEEDED FOR DRAINAGE AND RUNOFF CONTROL
3. TOPDRESS WITH CLEAN STONE AS NEEDED.
4. IMMEDIATELY REMOVE MUD AND SEDIMENT TRACKED OR WASHED ONTO PUBLIC ROADS BY BRUSHING OR
SWEEPING. FLUSHING SHOULD ONLY BE USED IF THE WATER IS CONVEYED INTO A SEDIMENT TRAP OR BASIN.
5. REPAIR ANY BROKEN ROAD PAVEMENT IMMEDIATELY.

INSTALLATION
1. FILL BAGS APPROXIMATELY HALF FULL WITH SAND OR FINE GRAVEL.
2. UPSLOPE FROM THE CURB INLET, LAY THE BAGS TIGHTLY END TO END IN A ROW CURVING FROM THE CURB
AND AWAY FROM THE INLET.
3. OVERLAP THE BARRIER ONTO THE CURB, AND EXTEND IT A MINIMUM OF 3 FT. INTO THE STREET TO
INTERCEPT THE RUNOFF.
4. IF USING MORE THAN ONE ROW, OVERLAP THE BAGS WITH THE ROW BENEATH, AND LEAVE A ONE -BAG GAP
IN THE MIDDLE OF THE TOP ROW TO SERVE AS A SPILLWAY.
5. FOR ADDITIONAL STORAGE CAPACITY, CONTRUCT A SERIES OF SANDBAG BARRIERS ALONG THE CURB SO EACH
ONE TRAPS SMALL AMOUNTS OF SEDIMENT.
6. PLACE SILT FENCE ONE FOOT BEHIND INLET. SEE DETAIL EC -2 FOR INSTALLATION.
7. IF INLET IS NOT LOCATED IN A SADDLE, THE BAGS ON THE DOWNSLOPE SIDE OF THE INLET ARE NOT
REQUIRED.
MAINTENANCE
1. INSPECT FREQUENTLY FOR DAMAGE BY VEHICULAR TRAFFIC, AND REPAIR IF NEEDED.
2. INSPECT AFTER EACH STORM EVENT.
3. REMOVE SEDIMENT (BUT NOT BY FLUSHING) WHEN IT REACHES HALF THE HEIGHT OF THE BARRIER.
4. DEPOSIT REMOVED SEDIMENT WHERE IT WILL NOT ENTER STORM DRAINS.
