RDANDY BAG
SILT FENCE INLET PROTECTION
INSTALLATION
1.DIG AN EIGHT-INCH DEEP, FOUR-INCH WIDE TRENCH AROUND THE PERIMETER OF THE
INLET.
2.IF USING PRE-ASSEMBLED GEOTEXTILE FABRIC AND POSTS, DRIVE THE POSTS INTO THE
SOIL, TIGHTLY STRETCHING THE GEOTEXTILE FABRIC BETWEEN POSTS AS EACH IS DRIVEN.
(POSTS MUST BE PLACED ON THE INLET SIDE OF THE ANCHOR TRENCH WITH THE
GEOTEXTILE FABRIC ON THE SIDE OF THE TRENCH FARTHEST FROM THE INLET.)
NOTE:IF ASSEMBLING THE GEOTEXTILE FABRIC AND POSTS ON-SITE, DRIVE THE POSTS INTO
THE SOIL AND THEN SECURE THE GEOTEXTILE FABRIC TO THE POSTS BY PLACING A PIECE
OF LATHE OVER THE FABRIC AND FASTENING IT TO THE POST
(STRETCHING THE FABRIC BETWEEN POSTS AS IT IS FASTENED).
3.USE THE WRAP JOIN METHOD WHEN JOINING POSTS.
4.PLACE THE BOTTOM 12 INCHES OF GEOTEXTILE FABRIC INTO THE EIGHT-INCH DEEP
TRENCH, LAYING THE REMAINING FOUR INCHES IN THE BOTTOM OF THE TRENCH AND
EXTENDING AWAY FROM THE INLET.
5.BACKFILL THE TRENCH WITH SOIL MATERIAL AND COMPACT IT IN PLACE.
6.BRACE THE POSTS BY NAILING BRACES INTO EACH CORNER POST OR UTILIZE RIGID
PANELS TO SUPPORT FABRIC.
NOTE: IN SITUATIONS WHERE STORM WATER MAY BYPASS THE STRUCTURE,
EITHER: SET THE TOP OF THE GEOTEXTILE FABRIC FILTER AT LEAST SIX INCHES LOWER THAN
THE GROUND ELEVATION ON THE DOWN-SLOPE SIDE OF THE STORM DRAIN INLET, BUILD A
TEMPORARY DIKE, COMPACTED TO SIX INCHES HIGHER THAN THE FABRIC, ON THE
DOWN-SLOPE SIDE OF THE STORM DRAIN INLET, AND/OR USE IN CONJUNCTION WITH
EXCAVATED DROP INLET PROTECTION.
MAINTENANCE
_ INSPECT DAILY.
_ INSPECT GEOTEXTILE FABRIC AND MAKE NEEDED REPAIRS IMMEDIATELY.
_ REMOVE SEDIMENT FROM POOL AREA TO PROVIDE STORAGE FOR THE NEXT STORM
EVENT. AVOID DAMAGING OR UNDERCUTTING FABRIC DURING SEDIMENT REMOVAL.
_ WHEN CONTRIBUTING DRAINAGE AREA HAS BEEN STABILIZED, REMOVE SEDIMENT,
PROPERLY DISPOSE OF ALL CONSTRUCTION MATERIAL, GRADE AREA TO THE ELEVATION
OF THE STORM DRAIN INLET TOP, THEN STABILIZE IMMEDIATELY.

BLOCK AND AGGREGATE INLET SEDIMENT DEVICE
INSTALLATION
1.EXCAVATE THE FOUNDATION FOR THE CONCRETE BLOCKS ON LEVEL GRADE AND AT LEAST TWO INCHES BELOW THE TOP OF THE STORM DRAIN INLET.
2.PLACE THE BOTTOM ROW OF CONCRETE BLOCKS AROUND THE PERIMETER OF THE STORM DRAIN. LAY BLOCKS WITH OPENINGS FACING UP, ABUTTING
THE BLOCKS FIRMLY TOGETHER AND OVERLAPPING THE CORNERS.
3.IF NECESSARY, SUPPORT THE BLOCKS BY DRIVING SHARPENED 2 X 4 INCH WOOD STUDS OR REBAR (NOT MORTAR) THROUGH THE BLOCK OPENINGS
AND INTO THE UNDERLYING SOIL.
4.ON EACH SIDE OF THE BOTTOM ROW, TURN ONE CONCRETE BLOCK WITH ITS OPENINGS FACING HORIZONTALLY TO ALLOW FOR DEWATERING.
5.PLACE HARDWARE CLOTH OVER THE OPENINGS TO HOLD THE AGGREGATE IN PLACE.
6.PLACE THE FILTER MEDIUM (INDOT CA NO. 5 AGGREGATE) AROUND THE OUTSIDE OF THE CONCRETE BLOCKS TO CONTROL DRAINAGE RATE; LIMIT
FILTER MEDIUM SIDE SLOPES TO 2:1 RATIO OR FLATTER.
NOTE: IN SITUATIONS WHERE STORM WATER MAY BYPASS THE STRUCTURE, EITHER:
_ SET THE TOP OF THE CONCRETE BLOCKS AT LEAST SIX INCHES LOWER THAN THE GROUND ELEVATION ON THE DOWN-SLOPE SIDE OF THE STORM DRAIN
INLET,
_ BUILD A TEMPORARY DIKE, COMPACTED TO SIX INCHES HIGHER THAN THE CONCRETE BLOCKS, ON THE DOWN-SLOPE SIDE OF THE STORM DRAIN INLET,
AND/OR
_ USE IN CONJUNCTION WITH EXCAVATED DROP INLET PROTECTION (SEE EXCAVATED DROP INLET PROTECTION ON PAGE 145).
MAINTENANCE
_ INSPECT DAILY.
_ REMOVE SEDIMENT AND DEBRIS AND MAKE NEEDED REPAIRS IMMEDIATELY.
_ WHEN THE CONTRIBUTING DRAINAGE AREA HAS BEEN STABILIZED, REMOVE AND PROPERLY DISPOSE OF ALL CONSTRUCTION MATERIAL AND SEDIMENT,
THEN STABILIZE.

- INSPECT DAILY.
- REMOVE ACCUMULATED SEDIMENT FROM PAVED AREA (DO NOT FLUSH WITH WATER) AFTER
EACH STORM EVENT. DEPOSIT SEDIMENT IN AN AREA WHERE IT WILL NOT RE-ENTER THE PAVED
AREA OR STORM DRAINS.
- INSPECT FOR DAMAGE BY VEHICULAR TRAFFIC AND REPAIR IF NEEDED.
_ WHEN CONTRIBUTING DRAINAGE AREA HAS BEEN STABILIZED, REMOVE SEDIMENT, PROPERLY
DISPOSE OF ALL CONSTRUCTION MATERIAL, GRADE AREA TO THE ELEVATION OF THE STORM
