1. WATTLES CAN BE PLACED AT THE TOP, ON THE FACE, OR AT THE TOE OF SLOPES TO INTERCEPT RUNOFF, REDUCE FLOW VELOCITY, RELEASE THE RUNOFF AS SHEET FLOW AND PROVIDE REMOVAL OF SEDIMENT

FROM THE RUNOFF.

2. WATTLES SHALL BE INSTALLED ALONG OR ON THE GROUND CONTOUR, AT THE TOE OF SLOPES, OR IN A DITCH TO HELP REDUCE THE EFFECTS OF SOIL EROSION AND RETAIN SEDIMENT. WATTLES SHOULD NOT

BE USED IN STREAMS.

3. FOR DITCH APPLICATIONS, THE MAXIMUM DRAINAGE AREA SHALL BE 15 ACRES. FOR SLOPE

APPLICATIONS, THE MAXIMUM DRAINAGE AREAS SHALL BE 1/4 ACRE PER 100 LF OF WATTLE.

4. WATTLES SHALL NOT BE USED ON PAVEMENT, ROCKY SOILS, OR AT ANY OTHER LOCATIONS WHERE THE

STAKES CANNOT BE DRIVEN TO THE REQUIRED DEPTH.

5. WATTLES SHALL BE MANUFACTURED FROM COCONUT FIBERS (COIR) THAT IS ENCLOSED BY A TUBULAR FLEXIBLE NETTING MATERIAL. ALL MATERIALS INCLUDING THE NETTING SHALL BE COIR FIBERS.

BOTTOM WITH STAGGERED JOINTS AS SHOWN.

10. FOR DITCH APPLICATIONS, WATTLES SHALL BE A MINIMUM OF 20 INCH DIAMETER AND SHALL BE PLACED PERPENDICULAR TO THE FLOW OF WATER. WATTLES SHALL CONTINUE UP THE SIDE SLOPES A MINIMUM OF 3 FEET PLUS THE DIAMETER OF THE WATTLE, OR TO THE TOP OF THE DITCH, WHICHEVER

IS LESS.

11. WATTLES USED IN SLOPE APPLICATIONS MAY REMAIN IN PLACE TO BIODEGRADE. FOR DITCH APPLICATIONS WATTLES SHALL BE COMPLETELY REMOVED AFTER FULLY ESTABLISHED VEGETATION HAS

COMPLETELY DEVELOPED.

12. WATTLES SHALL BE PAID FOR UNDER THE FOLLOWING ITEM NUMBERS:

15715, WATTLES, PER LINEAR FOOT

PAYMENT SHALL INCLUDE ALL MATERIALS (INCLUDING GEOTEXTILE FABRIC IF USED) AND LABOR

NECESSARY FOR CONSTRUCTION, MAINTENANCE, AND REMOVAL OF WATTLE.

13. SEDIMENT SHALL BE REMOVED FROM BEHIND THE WATTLE WHEN IT HAS ACCUMULATED TO ONE-HALF

THE ORIGINAL HEIGHT OF THE STRUCTURE.

NOTES:

1. FABRICATE ANNULAR, HELICAL AND SEMI-CORRUGATED TYPE COUPLING BANDS FROM THE SAME METAL AS THE CONNECTING PIPE. PROVIDE COUPLING BANDS NOT MORE THAN 2 NOMINAL SHEET THICKNESS THINNER THAN THE THICKNESS OF THE PIPE TO BE CONNECTED, AND NO THINNER THAN 0.052 INCH (18 GAGE) FOR STEEL OR 0.048 INCH (18 GAGE) FOR ALUMINUM. FASTEN COUPLING BANDS WITH THE

FOLLOWING SIZE OF BOLT:

3/8-INCH FOR PIPE DIAMETER - 18-INCH (21"X15" PIPE ARCH) OR LESS

1/2-INCH FOR PIPE DIAMETER - 21-INCH (24"X18" PIPE ARCH) OR MORE

2. FOR HELICALLY CORRUGATED PIPE WITH RE-ROLLED ENDS, THE NOMINAL CORRUGATION SIZE REFERS TO THE DIMENSION OF THE END

CORRUGATION IN THE PIPE.

3. USE ANNULAR CORRUGATED BANDS WITH PIPES HAVING ANNULAR CORRUGATIONS OR WITH HELICAL PIPE HAVING RE-ROLLED ENDS TO

FORM ANNULAR CORRUGATIONS.

4. USE HELICAL CORRUGATED BAND WITH PIPES HAVING HELICALLY CORRUGATED ENDS. HELICAL CULVERT INSTALLATIONS SHALL HAVE THE

ROLLED SEAM AT THE INLET PLACED IN THE LOWER ONE-HALF OF THE PIPE DIAMETER.

5. SMOOTH SLEEVE-TYPE COUPLERS AND FLAT BANDS MAY BE USED FOR PIPE DIAMETERS OF 12 INCHES OR LESS. USE A MATCHING METAL HAVING A NOMINAL THICKNESS OF NOT LESS THAT 0.040 INCH (20 GAGE) FOR STEEL, OR 0.036 INCH (20 GAGE) FOR ALUMINUM, OR A

PLASTIC WITH AN EQUIVALENT STRENGTH TO METAL.

6. ALL COUPLING BANDS SHALL HAVE A GASKET PER FP-24 SEC. 602.05 (B).

7. ALL CULVERT INSTALLATION OF 40-FEET AND LESS SHALL BE SINGLE PIECE WITH NO BAND.
