SUBSTITUTE. A SINGLE CONTINUOUS LENGTH OF FABRIC SHALL EXTEND ACROSS THE FULL WIDTH
OF THE BASIN.
2. POSTS SHALL BE STEEL, MINIMUM 5 FEET LONG, AND OF THE SAME GENERAL TYPE AS THOSE
SPECIFIED FOR SILT FENCE CONSTRUCTION.
3. THE TOP EDGE OF THE BAFFLE FABRIC SHALL BE SUPPORTED BY A TENSIONED CABLE OR ROPE
EXTENDING ACROSS THE WIDTH OF THE BASIN AND ANCHORED ON EACH END.
4. THE BOTTOM EDGE OF THE BAFFLE FABRIC SHALL BE EMBEDDED IN A TRENCH EXCAVATED ALONG
THE BASIN BOTTOM AND SIDE SLOPES.
5. BAFFLE FABRIC SHALL BE ATTACHED TO SUPPORT POSTS WITH HEAVY-DUTY PLASTIC CABLE TIES, OR SIMILAR MEANS.
6. BAFFLES SHALL BE SPACED IN THE DIRECTION OF FLOW TO PROVIDE THE SURFACE AREAS SHOWN.

MAINTENANCE NOTES:
1. INSPECT BAFFLES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL.
MAKE ANY REQUIRED REPAIRS IMMEDIATELY.
2. BE SURE TO MAINTAIN ACCESS TO THE BAFFLES. SHOULD THE FABRIC OF A
BAFFLE COLLAPSE, TEAR, DECOMPOSE, OR BECOME INEFFECTIVE,
REPLACE IT PROMPTLY.
3. REMOVE SEDIMENT DEPOSITS WHEN IT REACHES HALF FULL, TO PROVIDE
ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE
PRESSURE ON THE BAFFLES.
4. TAKE CARE TO AVOID DAMAGING THE BAFFLES DURING CLEANOUT, AND
REPLACE IF DAMAGED.
5. DURING CLEANOUT OPERATIONS. SEDIMENT DEPTH SHOULD NEVER
EXCEED HALF THE DESIGNED STORAGE DEPTH.
6. 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
