CONTRACTOR SHALL FOLLOW MANUFACTURER'S INSTRUCTIONS ON INSTALLATION.

FENCE AND ALL COMPONENTS SHALL BE BIODEGRADABLE, AND SHALL BE FUNCTIONAL FOR A MINIMUM OF

2 TO 2 YEARS.

SILT FENCES SHALL BE INSPECTED IMMEDIATELY AFTER EACH RAINFALL AND AT LEAST DAILY DURING PROLONGED RAINFALL EVENTS. ANY REPAIRS THAT ARE NECESSARY SHALL BE MADE IMMEDIATELY.

IF THE FABRIC OF THE SILT FENCE SHOULD DECOMPOSE OR BECOME INEFFECTIVE DURING THE EXPECTED

LIFE OF THE FENCE, THE FABRIC SHALL BE REPLACED PROMPTLY.

SEDIMENT DEPOSITS SHOULD BE INSPECTED AFTER EVERY STORM EVENT. THE DEPOSITS SHOULD BE REMOVED WHEN DEPOSITS HAVE REACHED APPROXIMATELY ONE-HALF THE HEIGHT OF THE BARRIER.

SEDIMENT DEPOSITS THAT ARE REMOVED SHALL BE GRADED AND VEGETATED TO CONFORM WITH THE

EXISTING TOPOGRAPHY.

1. BEGIN AT THE LOCATION WHERE THE SEDIMENTSTOP (Patent Pending) IS TO BE INSTALLED BY EXCAVATING A 3" DEEP X 9" WIDE TRENCH ALONG THE CONTOUR OF THE SLOPE. EXCAVATED SOIL SHOULD BE PLACED UP-SLOPE FROM THE ANCHOR TRENCH.

2. UNROLL THE SEDIMENTSTOP SO THE SECTION WITH THE 2' WIDE TOP NETTING IS THE DOWN SLOPE END (SPLASH APRON). THE SPLASH APRON OF THE SEDIMENTSTOP SHOULD COVER THE ANCHOR TRENCH ENSURING THAT APPROXIMATELY 12" (30 CM) IS EXTENDED BEYOND THE LOWER EDGE OF THE ANCHOR TRENCH. NOTE: SEEDING MUST BE CONDUCTED PRIOR TO INSTALLATION OF THE SEDIMENT STOP.

3. SECURE THE SEDIMENTSTOP IN THE ANCHOR TRENCH BY PLACING A ROW OF STAPLES/STAKES ON 12" (30 CM) CENTERS ACROSS THE ENTIRE LENGTH OF THE SEDIMENTSTOP. A SECOND ROW OF STAPLES/STAKES MUST BE PLACED ACROSS THE ENTIRE LOWER EDGE OF THE SEDIMENTSTOP SPLASH APRON ON APPROXIMATELY 12" (30 CM) CENTERS, STAGGERED WITH THE FIRST ROW OF STAPLES/STAKES.

4. BEGIN ROLLING THE SEDIMENTSTOP FROM ITS UPPER EDGE (UP-SLOPE EDGE) INTO A CONSISTENT ROLL DIAMETER UNTIL THE ROLL IS LOCATED IN THE ANCHOR TRENCH. IF A LARGER DIAMETER STRUCUTRE IS DESIRED, PLACE ADDITIONAL ORGANIC MATERIAL (I.E. STRAW, LEAVES, PINE NEEDLES OR LAWN CLIPPINGS) ACROSS THE ENTIRE WIDTH OF THE SEDIMENTSTOP PRIOR TO ROLLING. SEE DIAGRAM 4a FOR SEAMING OF ADJACENT

SEDIMENTSTOP ROLLS.

5. STOP ROLLING THE SEDIMENTSTOP WHEN THE ROLL IS LOCATED IN THE ANCHOR TRENCH.

6. SECURE THE SEDIMENTSTOP STRUCTURE TO THE SLOPE SURFACE BY DRIVING APPROXIMATELY 18" - 24" (45-60 CM) STAKES THROUGH THE CENTER OF THE ROLL EVERY 3' (0.9 M) ON CENTER. IF TWO SEDIMENTSTOP STRUCTURES ARE SEAMED TOGETHER ENSURE A STAKE IS DRIVEN THROUGH THE SEAM. THE FINAL STRUTURE'S DIAMETER WILL DICTATE STAKE LENGTH. LEAVE A SUFFICIENT AMOUNT OF STAKE EXPOSED ABOVE THE SEDIMENTSTOP TO ENSURE THE STRUCUTRE IS NOT COMPRESSED. BOTH LONGITUDINAL ENDS SHOULD BE ANGLED UP SLOPE.

7. BACKFILL AND COMPACT SOIL INTO THE UP-SLOPE PORTION OF THE ANCHOR TRENCH. SMOOTH AND LEVEL ANY SOIL REMAINING ABOVE THE SEDIMENTSTOP NOT USED TO FILL THE ANCHOR TRENCH. PLACE SEED ALONG UP-SLOPE PORTION OF SEDIMENTSTOP IF REQUIRED.
