INSTALLATION OF NETTING AND MATTING:
PRODUCTS DESIGNED TO CONTROL EROSION SHOULD BE INSTALLED
IN ACCORDANCE WITH MANUFACTURER'S INSTRUCTIONS. ANY MAT
OF BLANKET -TYPE PRODUCT USED AS A PROTECTIVE MULCH SHDULD
PROVDE COVER OF AT LEAST 30%OF THE SURFACE WHERE IT IS APPLIED,
I. APPLY FIVE, FERTILIZER AND SEED BEFORE LAYING THE NET OR MAT.
IF OPEN -WEAVE NETTING IS USED, TIME MAY BE INCORPORATED BEFORE
INSTALLING THE NET AND FERTILIZER AND SEED SPRAYED ON AFTERWARD.
2, START LAYING THE NET FROM THE TOP OF THE CHANNEL OR SLOPE AND
UNROLL IT DOWN THE GRADE. ALLOW NETTING TO LAY LOOSELY ON THE
SOIL BUT WITHOUT WRINKLES-00 NOT STRETCH.
3, TO SECURE THE NET, BURY 111E RESULTED END IN A SLOT OR TRENCH NO LESS
THAN 6-INCHES DEEP COVER MEET SOIL AND TAMP FIRMLY AS SHOWN IN
THIS DETAIL, STAPLE TFIE NET EVERY I2.-INCHES ACROSS THE TOP END AND
AN EVERY 3 FEET AROUND THE EDGES AND BOTTOM. WHERE 2 STRIPS OF
NET ARE LAID SIDE BY SIDE, THE ADJACENT EDGES SHOULD BE OVERLAPPED
34NCIEM STAPLED TOGETHER. EACH STRIP OF NETTING SHOULD ALSO BE
STAPLED DOWN THE CENTER, EVERY 3 FT. DO NOT STRETCH THE NET WHEN
APPLYING STAPLES.
MAINTENANCE:
INSPECT ALL MULCHES PERIODICALLY, AND AFTER RAINSTORMS TO CHECK
FOR RILL EROSION, DISLOCATION, OR FAILURE. WHERE EROSION IS OBSERVED,
APPLY ADDITIONAL MULCH. IF WASHOUT OCCURS, REPAIR TFIE SLOPE GRADE,
RESEED, AND REINSTALL MULCH. CONTINUE INSPECTIONS UNTIL VEGETATION
IS FIRMLY ESTABLISHED.

CONSTRUCTION SPECIFICATIONS:
1. PLACE STONE TO THE LINES AND DIMENSIONS SHOWN IN THE PLAN ON A FILTER
FABRIC FOUNDATION
2. KEEP THE CENTER STONE SECTION AT LEAST 9 INCHES BELOW NATURAL GROUND
LEVEL WHERE THE DATA ABUTS THE CHANNEL BANKS.
3, EXTEND STONE AT LEAST I,5-F BEYOND THE DITCH BANKS TO KEEP OVERFLOW
WATER FROM UNDERCUTTING THE MM AS IT RE-ENTERS THE CHANNEL.
4, SET SPACING BETWEEN DAMS TO ASSURE THAT THE ELEVATION A7 THE TOP OF THE
LOWER DAM IS THE SAME AS THE TOE ELEVATION OF 711E UPPER DAM.
5, PROTECT THE CHANNEL DOWNSTREAM FROM THE LOWEST CHECK DAM,
CONSIDERING THAT WATER WILL FLOW OVER AND AROUND THE DAM.
6, MAKE SURE THAT THE CHANNEL REACT{ ABOVE THE MOST UPSTREAM DAM
IS STABLE.
7, ENSURE THAT CHANNEL APPURTERANCES, SUCH AS CULVERT ENTRANCES BELOW
CHECK DAMS, ARE NOT SUBJECT TO DAMAGE OR BLOCKAGE FROM DISPLACED
STONES,
MAINTENANCE:
1. INSPECT CHECK DAMS AND CHANNELS FOR DAMAGE AFTER EACH RUNOFF
EVENT.
2. ANTICIPATE SUBMERGENCE AND DEPOSITION ABOVE THE CHECK DAM AND
EROSION FROM FLOWS AROUND THE EDGES OF THE DAM. CORRECT ALL
DAMAGE IMMEDIATELY, IF SIGNIFICANT EROSION OCCURS BETWEEN DANIS,
DEAL A PROTECTIVE RIPRAP LINER IN THAT PORTION OF THE CHANNEL.
3, REMOVE SEDIMENT ACCUMULATED BEHIND THE DAMS AS NEEDED TO PREVENT
DAMAGE TO CHANNEL VEGETATION, ALLOW THE CHANNEL TO DRAIN THROUGH
THE STONE CHECK DAM AND PREVENT LARGE FLOWS FROM CARVING SEDIMENT
OVER THE DATA. ADD STONES 70 DAMS AS NEEDED TO MAINTAIN DESIGN WEIGHT

MAINTENANCE:
MAINTAIN THE GRAVEL PA IN A CONDITION TO PREVE14T MUD OR SEDIMENT FROM LEAV III THE
CONSTRUCTION SITE. THIS MAY REQUIRE PERIODIC TOP DRESSING WITH 2 INCH STONE, AFTEREACH

SUBGRADE PREPARATION - PREPARE THE SUBGRADE FOR RIPRAP AND FILTER TO THE REQUIRED LINES
AND GRADES INDICATED ON THE PLANS. COMPACT ANY FlLL REQUIRED IN THE SUBGRADE TO A
DENSITY APPROXIMATING THAT OF THE SURROUNDING UNDISTURBED MATERIAL OR OVERFILL
DEPRESSIONS WILL RIPRAP. REMOVE BRUSH, TREES. STUMPS AND OTHER OBJECTIONABLE MATERIAL.
CUD THE SUBGRADE SUFFICIENTLY DEEP THAT THE EXISTED GRADE OF THE RIPRAP WILL BE AT THE
ELEVATION OF ME SURROUNDING AREA. CHANNELS SHOULD BE EXCAVATED SUFFICIENTLY TO ALLOW
PLACEMENT OF THE RIPRAP IN A MANNER SUCH THAT THE FINISHED INSIDE DIMENSIONS AND GRADE
OF THE RIPRAP MEET DESIGN SPECIFICATIONS.
SYNTHETIC FILTER FABRIC- PLACE THE FILTER FABRIC DIREGILYON THE PREPARED SURGRADE. OVERLAP
THE EDGES BYAT IEAST 12-INCIIES AND SPACE ANCHOR PINS EVERY 3-FEET ALONG THE OVERLAP. BURY
THE UPPER AND LOWER ENDS OF THE CLOTH A MINIMUM OF 12-INCHES BELOW GROUND. TAKE CARE
NOT TO DAMAGE THE CLOTH WHEN PLACING RIPMP, IF DANIAGE OCCURS, REMOVE THE RIPMP AND
REPAIR THE SHEET BY ADDING ANOTHER LAYER OF FILTER MATERIAL WITH A MINIMUM OVER AP OF
124NCHES AROUND THE DAMAGED AREA. IF EXIENSWE DAMAGE IS SUSPECTED, REMOVE AND REPLACE
THE ENTIRE SHEET
WHERE LARGE STONES ARE USED OR MACHINE PLACEMENT IS DIFFICULY, A 4INCH LAYER OF FINE
GRAVEL OR SAND MAY BE NEEDED TO PROTECT THE FILTER CLOTH-
STONE PLACEMENT - PLACEMENT OF RIPRAP SHOULD FOLLOW IMMEDIATELY AFTER PLACEMENT OF THE
FlLTER FABRIC. PLACE RIPRAP SO THAT IT FORMS A DENSE WELL GRADED MASS OF STONE WITH
MINIMUM OF VOIDS, THE DESIRED USTRIBUFION OF STONES THROUGHOUT THE MASS MAY BE OBTAINED
BY SELECTIVE LOADING AT THE QUARRY AND CONTROLLED DUMPING DURING FINAL PLACEMENT.
PLACE RIPRAP TO ITS FULL THICKNESS IN ONE OPERATION. DO NOT PLACE RIPRAP BY DUMPING
THROUGH CROPS OR OTHER METHODS THAT CAUSE SEGREGATION OF STONE SIZES. TAKE CARE NOT
TO DISLODGE THE UNDERLYING BASE OF FILTER FABRIC WHEN PLACING THE STONES.
THE FINISHED SLOPE SHOULD BE FREE OF POCKETS OF SMALL STONE OR CLUSTERS OF LARGE STORES,
HAND PLACING MAY BE NECESSARY TO ACHIEVE THE PROPER DISTRIBUTION OF STONE SIZES TO
PRODUCE A RELATIVELY SHROTH, UNIFORM SURFACE. THE FINISHED GRADE OF THE RIPMP SHOULD
BLEND (MATCH GRADE) WITH THE SURROUNDING AREA. NO OVERFALL OR PROTRUSION OF SPEND
SHOULD BE APPARENT WHICH WOULD IMPAIR STREAM FLOWS

2, ENSURE THAT THE HEIGHT OF THE SEDIMENT FENCE DOES NOT EXCEED 18 INCHES ABOVE THE GROUND
SURFACE (NIGHER FENCES MAY IMPOUND VOLUMES OF WATER SUFFICIENT TO CAUSE FAILURE OF 711E
STRUCTURE).
3. CONSTRUCT THE FILTER FABRIC FROM A CONTINUOUS ROLL CUT TO THE LENGTH OF THE BARRIER TO
AVOID JOINTS, WHEN JOINTS ARE NECESSARY, SECURELY FASTEN THE FILTER CLOTH ONLY AT

MAINTENANCE:
i. INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE AIRY REQUIRED
REPAIRS IMMEDIATELY. SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR
BECOME INNEFECTIVE, REPLACE IT PROMPTLY. REPLACE BURLAP EVERY BO DAYS,
2, 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
