C103 SWPPP DETAILSSEDIMENTATION/SILT FENCE
MAXIMUM LOAD SLOPE AND DISTANCE FOR
WHICH A SILT FENCE IS APPLICABLE
INSTALLATION
PREFABRICATED SILT FENCE
1. LAY OUT THE LOCATION OF THE FENCE SO THAT IT IS PARALLEL TO THE CONTOUR OF THE SLOPE AND AT LEAST 10 FEET BEYOND THE TOE OF THE SLOPE TO PROVIDE A SEDIMENT
STORAGE AREA. TURN THE ENDS OF THE FENCE UP SLOPE SUCH THAT THE POINT OF CONTACT BETWEEN THE GROUND AND THE BOTTOM OF THE FENCE END TERMINATES AT A HIGHER
ELEVATION THAN THE TOP OF THE FENCE AT ITS LOWEST POINT.
2. EXCAVATE AN EIGHT-INCH DEEP BY FOUR-INCH WIDE TRENCH ALONG THE ENTIRE LENGTH OF THE FENCE LINE. INSTALLATION BY PLOWING IS ALSO ACCEPTABLE.
3. INSTALL THE SILT FENCE WITH THE FILTER FABRIC LOCATED ON THE UP-SLOPE SIDE OF THE EXCAVATED TRENCH AND THE SUPPORT POSTS ON THE DOWN-SLOPE SIDE OF THE TRENCH.
4. DRIVE THE SUPPORT POSTS AT LEAST 18 INCHES INTO THE GROUND, TIGHTLY STRETCHING THE FABRIC BETWEEN THE POSTS AS EACH IS DRIVEN INTO THE SOIL. MINIMUM OF 12 INCHES
OF THE FILTER FABRIC SHOULD EXTEND INTO THE TRENCH.
5. LAY THE LOWER FOUR INCHES OF FILTER FABRIC ON THE BOTTOM OF THE TRENCH AND EXTEND IT TOWARD THE UP-SLOPE SIDE OF THE TRENCH.
6. BACKFILL THE TRENCH WITH SOIL MATERIAL AND COMPACT IT IN PLACE.
NOTE: IF THE SILT FENCE IS BEING CONSTRUCTED ON-SITE, ATTACH THE FILTER FABRIC TO THE SUPPORT POSTS AND ATTACH WOODEN LATHE TO SECURE THE FABRIC TO THE POSTS.
ALLOW FOR AT LEAST 12 INCHES OF FABRIC BELOW GROUND LEVEL. COMPLETE THE SILT FENCE INSTALLATION, FOLLOWING STEPS 1 THROUGH 6 ABOVE.
MAINTENANCE
_ INSPECT WITHIN 24 HOURS OF A RAIN EVENT AND AT LEAST ONCE EVERY SEVEN CALENDAR DAYS.
_ IF FENCE FABRIC TEARS, STARTS TO DECOMPOSE, OR IN ANY WAY BECOMES INEFFECTIVE, REPLACE THE AFFECTED PORTION IMMEDIATELY. NOTE: ALL REPAIRS SHOULD MEET
SPECIFICATIONS AS OUTLINED WITHIN THIS MEASURE.
_ REMOVE DEPOSITED SEDIMENT WHEN IT IS CAUSING THE FILTER FABRIC TO BULGE OR WHEN IT REACHES ONE-HALF THE HEIGHT OF THE FENCE AT ITS LOWEST POINT. WHEN
CONTRIBUTING DRAINAGE AREA HAS BEEN STABILIZED, REMOVE THE FENCE AND SEDIMENT DEPOSITS, GRADE THE SITE TO BLEND WITH THE SURROUNDING AREA, AND STABILIZE.

1.UTILIZE AND FOLLOW THE DESIGN IN THE STORM WATER POLLUTION PREVENTION
PLAN TO INSTALL THE SYSTEM.
2.DEPENDENT UPON THE TYPE OF SYSTEM, EITHER EXCAVATE THE PIT OR INSTALL THE
CONTAINMENT SYSTEM.
3.A BASE SHALL BE CONSTRUCTED AND PREPARED THAT IS FREE OF ROCKS AND
OTHER DEBRIS THAT MAY CAUSE TEARS OR PUNCTURES IN THE POLYETHYLENE
LINING.
4.INSTALL THE POLYETHYLENE LINING. FOR EXCAVATED SYSTEMS, THE LINING SHOULD
EXTEND OVER THE ENTIRE EXCAVATION. THE LINING FOR BERMED SYSTEMS SHOULD
BE INSTALLED OVER THE POOLING AREA WITH ENOUGH MATERIAL TO EXTEND THE
LINING OVER THE BERM OR CONTAINMENT SYSTEM. THE LINING SHOULD BE SECURED
WITH PINS, STAPLES, OR OTHER FASTENERS.
5.PLACE FLAGS, SAFETY FENCING, OR EQUIVALENT TO PROVIDE A BARRIER TO
CONSTRUCTION EQUIPMENT AND OTHER TRAFFIC.
6.PLACE A NON-COLLAPSING, NON-WATER HOLDING COVER OVER THE WASHOUT
FACILITY PRIOR TO A PREDICTED RAINFALL EVENT TO PREVENT ACCUMULATION OF
WATER AND POSSIBLE OVERFLOW OF THE SYSTEM (OPTIONAL).
7.INSTALL SIGNAGE THAT IDENTIFIES CONCRETE WASHOUT AREAS.
8.POST SIGNS DIRECTING CONTRACTORS AND SUPPLIERS TO DESIGNATED LOCATIONS.
9.WHERE NECESSARY, PROVIDE STABLE INGRESS AND EGRESS (SEE TEMPORARY
CONSTRUCTION INGRESS/EGRESS PAD ON PAGE 17) OR ALTERNATIVE APPROACH PAD
FOR CONCRETE WASHOUT SYSTEMS.
10.USE A 10 MIL. POLYETHYLENE LINED DUMPSTER AS AN ALTERNATE.

INSTALLATION: REMOVE THE GRATE FROM CATCH BASIN. IF USING OPTIONAL OIL
ABSORBENTS; PLACE ABSORBENT PILLOW IN UNIT. STAND THE GRATE ON END. MOVE THE
TOP LIFTING STRAPS OUT OF THE WAY AND PLACE THE GRATE INTO THE DANDY BAG®II SO
THAT THE GRATE IS BELOW THE TOP STRAPS AND ABOVE THE LOWER STRAPS. HOLDING
THE LIFTING DEVICES, INSERT THE GRATE INTO THE INLET.
MAINTENANCE: REMOVE ALL ACCUMULATED SEDIMENT AND DEBRIS FROM VICINITY OF UNIT
AFTER EACH STORM EVENT. AFTER EACH STORM EVENT AND AT REGULAR INTERVALS,
LOOK INTO THE DANDY BAG®II. IF THE CONTAINMENT AREA IS MORE THAN 1/3 FULL OF
SEDIMENT, THE UNIT MUST BE EMPTIED. TO EMPTY UNIT, LIFT THE UNIT OUT OF THE INLET
USING THE LIFTING STRAPS AND REMOVE THE GRATE. IF USING OPTIONAL OIL
ABSORBENTS; REPLACE ABSORBENT WHEN NEAR SATURATION.

NOTE: AVOIDING DAMAGE DURING CONSTRUCTION
THE SUREST WAY TO PROTECT TREES THAT ARE TO BE SAVED IS TO:
1.WORK WITH THE BUILDER TO LOCATE AND MARK WITH FLAGGING AND/OR SIGNS ALL
CONSTRUCTION ROADS, PARKING PLACES FOR WORKERS, AND AREAS FOR STORAGE OF
BUILDING MATERIALS, GRAVEL AND SOIL.
2.WORK WITH THE UTILITY CONTRACTORS TO STAKE OUT THE EXACT LOCATION OF
TRENCHES.
3.ERECT PHYSICAL BARRIERS AROUND ALL "SAVED" TREES OR, BETTER YET, AROUND
GROUPS OF TREES, NEAR THE CONSTRUCTION ACTIVITY.
4.EXTEND BARRIERS AS FAR AS POSSIBLE BEYOND DRIPLINE.

1.REFERENCED IN CHAPTER 7 PAGE 97 IN THE INDIANA STORM WATER QUALITY MANUAL.

BE EQUAL TO THE ELEVATION OF
THE TOP OF THE SUCCEEDING
DOWNSTREAM BERM.

INSTALLATION
1.LAY OUT THE LOCATION OF THE CHECK DAM.
2.EXCAVATE A CUTOFF TRENCH INTO THE CHANNEL BOTTOM AND DITCH
BANKS, EXTENDING IT A MINIMUM OF 18 INCHES BEYOND THE TOP OF
THE DITCH BANK.
3.INSTALL AND ANCHOR FILTER FABRIC IN THE CHANNEL AND CUTOFF
TRENCH.
4.PLACE RIPRAP IN THE CUTOFF TRENCH AND CHANNEL TO THE LINES
AND DIMENSIONS SHOWN IN THE CONSTRUCTION PLANS. THE CENTER
OF EACH DAM MUST BE AT LEAST NINE INCHES LOWER THAN THE
UPPERMOST POINTS OF CONTACT BETWEEN THE RIPRAP DAM AND
CHANNEL BANKS (SEE ROCK CHECK DAM WORKSHEET ON PAGE 101).
5.EXTEND THE RIPRAP AT LEAST 18 INCHES BEYOND THE TOP OF THE
CHANNEL BANKS TO KEEP OVERFLOW WATER FROM ERODING AREAS
ADJACENT TO THE CHANNEL BANKS BEFORE IT RE-ENTERS THE
CHANNEL.
6.PLACE FILTER MEDIUM (INDOT CA NO. 5 AGGREGATE) ON THE UP-SLOPE
SIDE OF THE DAM. PLACE FILTER MEDIUM OVER THE ENTIRE FACE OF
THE DAM UP TO THE BASE OF THE OVERFLOW WEIR NOTCH.
7.STABILIZE THE CHANNEL ABOVE THE UPPERMOST DAM.
8.INSTALL AN EROSION-RESISTANT LINING IN THE CHANNEL BELOW THE
LOWERMOST DAM. THE LINING SHOULD EXTEND A MINIMUM DISTANCE
OF SIX FEET BELOW THE DAM.
9.ADDITIONAL SEDIMENT STORAGE CAN BE PROVIDED BY EXCAVATING A
SMALL SEDIMENT TRAP ON THE UPSTREAM SIDE OF THE CHECK DAM.
MAINTENANCE
- INSPECT WITHIN 24 HOURS OF EACH RAIN EVENT AND AT LEAST ONCE
EVERY SEVEN CALENDAR DAYS.
- IF SIGNIFICANT EROSION OCCURS BETWEEN DAMS, INSTALL AN
EROSION-RESISTANT LINER IN THAT PORTION OF THE CHANNEL.
- REMOVE ACCUMULATED SEDIMENT WHEN IT REACHES ONE-HALF THE
HEIGHT OF THE DAM TO MAINTAIN CHANNEL CAPACITY, ALLOW DRAINAGE
THROUGH THE DAM, AND PREVENTLARGE FLOW FROM DISPLACING
SEDIMENT.
- ADD RIPRAP AND AGGREGATE AS NEEDED TO MAINTAIN DESIGN HEIGHT
AND CROSS SECTION OF THE DAMS.
- WHEN DAMS ARE NO LONGER NEEDED, REMOVE THE RIPRAP AND
AGGREGATE AND STABILIZE THE CHANNEL, USING AN
EROSION-RESISTANT LINING IF NECESSARY. (RIPRAP AND AGGREGATE
FROM THE DAM MAY BE REMOVED OR UTILIZED TO STABILIZE THE
CHANNEL.)
