<br />SILT FENCE: THIS SEDIMENT BARRIER UTILIZES STANDARD STRENGTH OR EXTRA
<br />STRENGTH SYNTHETIC FILTER FABRICS, IT IS DESIGNED FOR SITUATIONS IN
<br />WHICH ONLY SHEET OR OVERLAND FLOWS ARE EXPECTED.
<br />1. THE HEIGHT OF A SILT FENCE SHALL NOT EXCEED 36 INCHES (HIGHER FENCES
<br />MAY IMPOUND VOLUMES OF WATER SUFFICIENT TO CAUSE FAILURE OF THE
<br />STRUCTURE).
<br />2. THE FILTER FABRIC SHALL BE PURCHASED IN A CONTINUOUS ROLL CUT TO
<br />THE LENGTH OF THE BARRIER TO AVOID THE USE OF JOINTS. WHEN JOINTS
<br />ARE NECESSARY, FILTER CLOTH SHALL BE SPLICED TOGETHER ONLY AT A
<br />SUPPORT POST, WITH A MINIMUM 6 -INCH OVERLAP, AND SECURELY SEALED.
<br />3. POSTS SHALL BE SPACED A MAXIMUM OF 6 FEET APART AT THE BARRIER
<br />LOCATION AND DRIVEN SECURELY INTO THE GROUND (MINIMUM OF 30 INCHES).
<br />4. A TRENCH SHALL BE EXCAVATED APPROXIMATELY 8 INCHES WIDE AND 12 INCHES
<br />DEEP ALONG THE LINE OF POSTS AND UPSLOPE FROM THE BARRIER.
<br />5. WHEN STANDARD STRENGTH FILTER FABRIC IS USED, A WIRE MESH SUPPORT
<br />FENCE SHALL BE FASTENED SECURELY TO THE UPSLOPE SIDE OF THE POSTS
<br />USING HEAVY DUTY WIRE STAPLES AT LEAST 1 INCH LONG, TIE WIRES OR
<br />HOG RINGES. THE WIRE SHALL EXTEND INTO THE TRENCH A MINIMUM OF 4
<br />INCHES AND SHALL NOT EXTEND MORE THAN 36 INCHES ABOVE THE ORIGINAL
<br />GROUND SURFACE.
<br />6. THE STANDARD STRENGTH FILTER FABRIC SHALL BE STAPLED OR WIRED TO
<br />THE FENCE, AND 20 INCHES OF THE FABRIC SHALL BE EXTENDED INTO THE
<br />TRENCH. THE FABRIC SHALL NOT EXTEND MORE THAN 36 INCHES ABOVE THE ORIGINAL
<br />GROUND SURFACE FILTER FABRIC SHALL NOT BE STAPLED TO EXISTING TREES
<br />7. WHEN EXTRA STRENGTH FILTER FRABRIC AND CLOSER POST SPACING ARE USED,
<br />THE WIRE MESH SUPPORT FENCE MAY BE ELIMINATED. IN SUCH A CASE, THE
<br />OTHER PROVISIONS OF ITEM NO. 6 APPLYING.
<br />8 THE TRENCH SHALL RE RACKFILLED WITH 3/4 INCH MINIMUM DIAMETER WASHED GRAVEL.
<br />9. SILT FENCE SHALL BE REMOVED WHEN THEY HAVE SERVED THEIR USEFUL PUR-
<br />POSE, BUT NOT BEFORE THE UPSLOPE AREA HAS BEEN PERMANENTLY STABILIZED
<br />MAINTENANCE:
<br />1. SILT FENCES AND FILTER BARRIERS SHALL BE INSPECTED IMMEDIATELY AFTER
<br />EACH RAINFALL AND AT LEAST DAILY DURING PROLONGED RAINFALL. ANY
<br />REQUIRED REPAIRS SHALL BE MADE IMMEDIATELY.
<br />2. SHOULD THE FABRIC ON A SILT FENCE OR FILTER BARRIER DECOMPOSE OR
<br />BECOME INEFFECTIVE PRIOR TO THE END OF THE EXPECTED USABLE LIFE AND
<br />THE BARRIER STILL BE NECESSARY, THE FABRIC SHALL BE REPLACED PROMPTLY.
<br />3. SEDIMENT DEPOSITES SHOULD BE REMOVED AFTER EACH STORM EVENT. THEY
<br />MUST BE REMOVED WHEN DEPOSITES REACH APPROXIMATELY ONE -HALF THE HEIGHT
<br />OF THE BARRIER.
<br />4. ANY SEDIMENT DEPOSITES REMAINING IN PLACE AFTER THE SILT FENCE OR
<br />FILTER BARRIER IS NO LONGER REQUIRED SHALL BE DRESSED TO CONFORM
<br />WITH THE EXISTING GRADE, PREPARED AND SEEDED.
