INSTALLATION:
WHEN INSTALLING RUNNING LENGTHS OF WATTLES, BUTT THE SECOND
WATTLE TIGHTLY AGAINST THE FIRST, DO NOT OVERLAP THE ENDS. STAKE
THE WATTLES AT EACH END AND FOUR FOOT ON CENTER. FOR EXAMPLE:
A 25 FOOT WATTLE USES 6 STAKES
A 20 FOOT WATTLE USES 5 STAKES
A 12 FOOT WATTLE USES 4 STAKES
STAKES SHOULD BE DRIVEN THROUGH THE MIDDLE OF THE WATTLE.
LEAVING 2 - 3 INCHES OF THE STAKE PROTRUDING ABOVE THE WATTLE. A
HEAVY SEDIMENT LOAD WILL TEND TO PICK THE WATTLE UP AND COULD
PULL IT OFF THE STAKES IF THEY ARE DRIVEN DOWN TOO LOW. IT MAY BE
NECESSARY TO MAKE A HOLE IN THE WATTLE WITH A PICK END OF YOUR
MADDOX IN ORDER TO GET THE STAKE THROUGH THE STRAW. WHEN
STRAW WATTLES ARE USED FOR FLAT GROUND APPLICATIONS, DRIVE THE
STAKES STRAIGHT DOWN; WHEN INSTALLING WATTLES ON SLOPES, DRIVE
THE STAKES PERPENDICULAR TO THE SLOPE.
DRIVE THE FIRST END STAKE OF THE SECOND WATTLE AT AN ANGLE
TOWARD THE FIRST WATTLE IN ORDER TO HELP ABUT THEM TIGHTLY
TOGETHER. IF YOU HAVE DIFFICULTY DRIVING THE STAKE INTO EXTREMELY
HARD OR ROCKY SLOPES, A PILOT BAR MAY BE NEEDED TO BEGIN THE
STAKE HOLE.

INSTALLATION:
STAKES SHOULD BE DRIVEN ACROSS FROM EACH OTHER
AND ON EACH SIDE OF THE WATTLE. LEAVING 4"-6" OF
STAKE PROTRUDING ABOVE THE WATTLE. BAILING WIRE OR
NYLON ROPE SHOULD BE TIED TO THE STAKES ACROSS
THE WATTLE. STAKES SHOULD THEN BE DRIVEN UNTIL THE
BAILING WIRE OR NYLON ROPE IS SUFFICIENTLY SNUG TO
THE WATTLE.
WHEN INSTALLING RUNNING LENGTHS OF WATTLES, TO
PREVENT SHIFTING, BUTT THE SECOND WATTLE TIGHTLY
AGAINST THE FIRST. DO NOT OVERLAP THE ENDS. STAKES
SHOULD BE DRIVEN 1 FT. FROM END, ACROSS FROM AND
ON EACH SIDE OF WATTLE LEAVING 4"-6" OF STAKE
PROTRUDING ABOVE THE WATTLE. BAILING WIRE OR
NYLON ROPE SHOULD BE TIED TO STAKES IN AN HOUR
GLASS FORMATION (FRONT TO BACK OF WATTLE "A",
ACROSS TO FRONT OF WATTLE "B", ACROSS TO BACK AND
BACK TO FRONT OF WATTLE "A"). STAKES SHOULD THEN BE

W1 & W2 INSTALLATION NOTES:
1. THE LOCATION AND LENGTH OF WATTLE IS DEPENDENT ON THE CONDITIONS OF EACH SITE.
2. WATTLES SHALL BE INSTALLED PRIOR TO ANY LAND-DISTURBING ACTIVITIES.
3. WATTLES SHALL CONSIST OF STRAW, COMPOST, EXCELSIOR, OR COCONUT FIBER.
4. NOT FOR USE IN CONCENTRATED FLOW AREAS.
5. THE WATTLES SHALL BE TRENCHED INTO THE GROUND A MINIMUM OF TWO (2) INCHES.
6. WATTLES SHALL BE INSTALLED PER MANUFACTURERS SPECIFICATIONS.
7. ON SLOPES, WATTLES SHOULD BE INSTALLED ON CONTOUR WITH A SLIGHT DOWNWARD ANGLE AT THE END OF THE ROW IN ORDER TO PREVENT
PONDING AT THE MID SECTION.
8. RUNNING LENGTHS OF WATTLES SHOULD BE ABUTTED FIRMLY TO ENSURE NO LEAKAGE AT THE ABUTMENTS.
9. SPACING - DOWNSLOPE:
10. VERTICAL SPACING FOR SLOPE INSTALLATIONS SHOULD BE DETERMINED BY SITE CONDITIONS. SLOPE GRADIENT AND SOIL TYPE ARE THE MAIN
FACTORS. A GOOD RULE OF THUMB IS:
1:1 SLOPES = 10 FEET APART
2:1 SLOPES = 20 FEET APART
3:1 SLOPES = 30 FEET APART
4:1 SLOPES = 40 FEET APART, ETC.
11. HOWEVER, ADJUSTMENTS MAY HAVE TO BE MADE FOR THE SOIL TYPE: FOR SOFT, LOAMY SOILS - ADJUST THE ROWS CLOSER TOGETHER; FOR HARD,
ROCKY SOILS - ADJUST THE ROWS FURTHER APART. A SECONDARY WATTLE PLACED BEHIND THE ABUTMENT OF TWO WATTLES IS ENCOURAGED ON
STEEP SLOPES OR WHERE JOINTS HAVE FAILED IN THE PAST.
12. STAKING: THE CITY RECOMMENDS USING WOOD STAKES TO SECURE THE WATTLES. 1/2" TO 5/8" REBAR IS ALSO ACCEPTABLE. BE SURE TO USE A
STAKE THAT IS LONG ENOUGH TO PROTRUDE SEVERAL INCHES ABOVE THE WATTLE: 18" IS A GOOD LENGTH FOR HARD, ROCKY SOIL. FOR SOFT LOAMY
SOIL USE A 24" STAKE.
4"-6" ABOVE WATTLE AFTER BAILING WIRE
OR NYLON ROPE IS ATTACHED. STAKES
NEED TO BE TAMPED UNTIL WIRE/ROPE IS
SNUG WITH WATTLE.

THE CONTRACTOR SHALL INSPECT WATTLES EVERY TWO WEEKS AND AFTER ANY SIGNIFICANT STORM EVENT AND MAKE REPAIRS OR REMOVE SEDIMENT
ACCUMULATED BEHIND WATTLE AS NECESSARY.
SEDIMENT ACCUMULATED BEHIND WATTLE SHALL BE REMOVED WHEN THE SEDIMENT HAS ACCUMULATED TO ONE HALF THE DIAMETER OF THE WATTLE.
