INSTALLATION NOTE:
USE SILT FENCE ONLY WHEN DRAINAGE AREA
DOES NOT EXCEED 1/4 ACRE AND NEVER IN
AREAS OF CONCENTRATED FLOW.
MAINTENANCE NOTES:
cM
1. 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.
2. REMOVE ALL FENCING MATERIALS AND UNSTABLE _
SEDIMENT DEPOSITS AND BRING THE AREA TO o
GRADE AND STABILIZE IT AFTER THE N
CONTRIBUTING DRAINAGE AREA HAS BEEN
PROPERLY STABILIZED.

4. IN THE EVENT STAKING IS NOT POSSIBLE (I.E., WHEN SOCKS ARE USED ON CURBSIDE SECTION
PAVEMENT) HEAVY CONCRETE BLOCKS OR SAND BAGS SHALL BE USED BEHIND THE
SOCK TO HOLD IT IN PLACE DURING RUNOFF EVENTS.
5. THE ENDS OF THE SOCKS SHOULD BE TURNED SLIGHTLY UP SLOPE TO PREVENT
RUNOFF FROM GOING AROUND THE END OF THE SOCKS.
