PERMANENT RIPRAP INSTALLATIONS.
4.SLOPE: 2:1 OR FLATTER, UNLESS APPROVED IN THE EROSION AND
SEDIMENT CONTROL PLAN.
5.MINIMUM THICKNESS: THREE TIMES THE SPECIFIED D50 STONE
DIAMETER.
INSTALLATION REQUIREMENTS:
SUBGRADE PREPARATION:
1.REMOVE BRUSH, TREES, STUMPS, AND OTHER DEBRIS.
2.EXCAVATE ONLY DEEP ENOUGH FOR BOTH FILTER AND RIPRAP;
OVER-EXCAVATION INCREASES THE AMOUNT OF SPOIL
CONSIDERABLY.

SURROUNDING UNDISTURBED SOIL.
4.CUT A KEYWAY IN STABLE MATERIAL AT THE BASE OF THE SLOPE TO
REINFORCE THE TOE; KEYWAY DEPTH SHOPULD BE 1.5 TIMES THE
DESIGN THICKNESS OF THE RIPRAP AND SHOULD EXTEND A
HORIZONTAL DISTANCE EQUAL TO THE DESIGN THICKNESS.

FILTER PLACEMENT:
1.IF USING GEOTEXTILE FABRIC, PLACE IT ON THE SMOOTHED
FOUNDATION, OVERLAP THE EDGES AT LEAST 12 INCHES, AND
SECURE WITH ANCHOR PINS SPACED EVERY 3 FOOT ALONG THE
OVERLAP.
2.IF USING A SAND/GRAVEL FILTER, SPREAD THE WELL-GRADED
AGGREGATE IN A UNIFORM LAYER TO THE REQUIRED THICKNESS (6
INCH MAXIMUM); IF TWO OR ORE LAYERS ARE SPECIFIED, PLACE
THE LAYER OF SMALLER GRADATION FIRST, AND AVOID MIXING THE
LAYERS.
RIPRAP PLACEMENT:
1.IMMEDIATELY AFTER INSTALLING THE FILTER, ADD THE RIPRAP TO
THE FULL THICKNESS IN ONE OPERATION. (DO NOT DUMP THROUGH
CHUTES OR USE ANY METHOD THAT CAUSES SEGREGATION OF
ROCK SIZES OR THAT WILL DISLODGE OR DAMAGE THE UNDERLYING
FILTER MATERIAL).
2.IF FABRIC IS DAMAGED, REMOVE THE RIPRAP AND REPAIR BY
ADDING ANOTHER LAYER OF FABRIC, OVERLAPPING THE DAMAGED
AREA BY 12 INCHES.
3.PLACE SMALLER ROCK IN VOIDS TO FORM A DENSE, UNIFORM,
WELL-GRADED MASS. (SELECTIVE LOADING AT THE QUARRY AND
SOME HAND PLACEMENT MAY BE NEEDED TO ENSURE AN EVEN
DISTRIBUTION OF ROCK MATERIAL).
4.BLEND THE ROCK SURFACE SMOOTHLY WITH THE SURROUNDING
AREA TO ELIMINATE PROTRUSIONS OR OVERFALLS.
MAINTENANCE:
1.INSPECT PERIODICALLY FOR DISPLACED ROCK MATERIALS,
SLUMPING, AND EROSION AT EDGES, ESPECIALLY DOWNSTREAM OR
DOWNSLOPE. (PROPERLY DESIGNED AND INSTALLED RIPRAP
USUALLY REQUIRES VERY LITTLE MAINTENANCE IF PROMPTLY
REPAIRED).
