BAFFLE CONSTRUCTION SPECIFICATION:
1. GRADE THE BASIN SO THAT THE BOTTOM IS LEVEL FRONT TO BACK AND SIDE TO SIDE.
2. INSTALL THE COIR FIBER BAFFLES IMMEDIATELY UPON EXCAVATION OF THE BASINS.
3. INSTALL POSTS ACROSS THE WIDTH OF THE SEDIMENT TRAP.
4. STEEL POSTS SHOULD BE DRIVEN TO A DEPTH OF 24 INCHES AND SPACED A MAXIMUM OF 4 FEET APART. 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 EARTHEN EMBANKMENT.
5. 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.
6. ATTACH A 9 GAUGE HIGH TENSION WIRE STRAND TO THE STEEL POSTS AT A HEIGHT OF 6 INCHES ABOVE THE SPILLWAY
ELEVATION WITH PLASTIC TIES OR WIRE FASTENERS TO PREVENT SAGGING. IF THE TEMPORARY SEDIMENT BASIN WALL BE
CONVERTED TO A PERMANENT STORMWATER BASIN OF A GREATER DEPTH, THE BAFFLE HEIGHT SHOULD BE BASED ON THE
POOL DEPTH DURING USE AS A TEMPORARY SEDIMENT BASIN.
7. EXTEND 9 GAUGE MINIMUM HIGH TENSION WIRE STRAND TO SIDE OF BASIN OR INSTALL STEEL T-POSTS TO ANCHOR BAFFLE TO
SIDE OF BASIN AND SECURE TO VERTICAL END POSTS.
8. DRAPE THE COIR FIBER MAT OVER THE WIRE STRAND MOUNTED AT A HEIGHT OF 6 INCHES ABOVE THE SPILLWAY ELEVATION.
SECURE THE COIR FIBER MAT TO THE WARE STRAND WITH PLASTIC TIES OR WARE FASTENERS. ANCHOR THE MATTING TO THE
SIDES AND FLOOR OF THE BASIN 'NTH 12 INCH WIRE STAPLES, APPROXIMATELY 1 FT APART, ALONG THE BOTTOM AND SIDE
SLOPES OF THE BASIN.
9. DO NO SPLICE THE FABRIC, BUT USE A CONTINUOUS PIECE ACROSS THE BASIN.
10. ADJUSTMENTS MAY BE REQUIRED IN THE STAPLING REQUIREMENTS TO FIT INDIVIDUAL SITE CONDITIONS.

GENERAL NOTES:
1. CONTRACTOR IS RESPONSIBLE FOR FIELD VERIFYING ALL
EXISTING UTILITIES, ABOVE AND BELOW GROUND, PRIOR TO
COMMENCING CONSTRUCTION.
2. CONTRACTOR IS RESPONSIBLE FOR DISPOSAL OF ALL WASTE
MATERIALS GENERATED THROUGH DEMOLITION AND GRUBBING
ACTIVITIES.
3. THE AREAS OF ENVIRONMENTAL CONCERN AS SHOWN ON THIS
MAP WERE DELINEATED BY GARY MITCHEL OF THE CLARK
ENVIRONMENTAL GROUP AND DELIVERED TO COASTAL LAND
DESIGN IN OCTOBER, 2005.
4. THE DISTURBANCE FOR THIS SITE IS TO BE KEPT TO A
MINIMUM.
5. ALL DISTURBED AREAS NOT WITHIN THE PROPOSED BACK OF
CURB (BOC) TO BE SEEDED, FERTILIZED, AND MULCHED WITHIN
15 CALENDAR DAYS OF GRADING ACTIVITIES.
6. ALL STORMDRAIN DEVICES ARE TO PROVIDE POSITIVE DRAINAGE.
7. EROSION AND SEDIMENTATION CONTROL PRACTICES ARE TO
REMOVED IN THE LOCATION THAT THE STORMWATER SYSTEM IS
BEING INSTALLED AT THAT TIME.
8. STORMWATER PUMPS ARE TO BE PROVIDED FOR OPERATION
AND MAINTENANCE AND EMERGENCY DRAINAGE OF EACH POND.
