SUBJECT TO SEEPAGE OR HIGH WATER TABLE.
MAINTENANCE:
MAINTAIN THE GRAVEL PAD IN A CONDITION TO PREVENT MUD OR SEDIMENT FROM LEAVING THE
CONSTRUCTION SITE. THIS MAY REQUIRE PERIODIC TOP DRESSING WITH 2-INCH STONE. AFTER EACH

MATERIAL SPECIFICATIONS:
1. USE A SYNTHETIC FILTER FABRIC OF AT LEAST 65% BY WEIGHT OF POLYOLERNS OR POLYESTER, WHICH
IS CERTIFIED BY THE MANUFAMFIER OR SUPPLIER AS CONFORMING TO THE REQUIREMENTS IN ASTM
06461.
2. SYNTHETIC FILTER FABRIC SHOULD CONTAIN ULTRAVIOLET RAY INHIBITORS AND STABILIZERS,
3. ENSURE THAT POSTS FOR SEDIMENT FENCES ARE 1,33 LB/LINEAR FEET STEEL WITH A MINIMUM LENOD I
OF 5-FEET, MAKE SURE THAT STEEL POSTS NAVE PROJECTIONS TO FACILITATE FASTENING THE FABRIC.
A. FAA RaNFORCURNT U STANDARD STRENGTH FILTER FABRIC, wE WIRE FENCE WITH A MINIMUM 14-
GUAGE AND A MAXIMUM MESH SPACING OF 6-INCHES.
CONSTRUCTION SPECIFICATIONS:
1. CONSTRUCT THE SEDIMENT BARRIER OF STANDARD STRENGTH OR EXTRA STRENGTH SYNTHETIC FILTEF
FABRICS.
2. ENSURE THAT THE HEIGHT OF THE SEDIMENT FENCE DOES NOT EXCEED 18-INCHES ABOVE THE GROUND
SURFACE (HIGHER FENCES MAY IMPOUND VOLUMES OF WATER SUFFICIENT TO CAUSE FAILURE OF THE
STRUCTURE).
3. CONSTRUCT THE FILTER FABRIC FROM A CONTINUOUS ROLL CUT TO THE LENGTH OF THE BARRIER TO
AVOID JOINTS. WHEN JOINTS ARE NECESSARY, SECURELY FASTEN THE FILTER CLOTH ONLY AT A
SUPPORT POST WITH OVERLAP TO THE NEXT POST.

SUPPORT POSTS SHOULD BE DRIVEN SECURELY INTO THE GROUND TO A MINIMUM OF 18-INCHES.
WIRE MESH SUPPORT FENCE MATERIAL SHALL BE AGRICULTURAL QUALITY 14-GAGE ANNEALED
STEEL WIRE WITH A 4' x 5° MAX. SPACING PATTERN.
6. EXTRA STRENGTH FILTER FABRIC WITH 6-FT POST SPACING DOES NOT REQUIRE WIRE MESH SUPPORT

7. EXCAVATE A TRENCH APPROXIMATELY 4-INCHES WIDE AND 8-INCHES DEEP ALONG THE PROPOSED
LINE OF POSTS AND UPSLOPE FROM THE BARRIER.
8. BACKFILL THE TRENCH WITH COMPACTED SOIL PLACED OVER THE FILTER FABRIC.
9. DO NOT ATTACH FILTER FABRIC TO EXISTING TREES.
MAINTENANCE:
1. INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY REQUIRED
REPAIRS IMMEDIATELY. SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR
BECOME INEFFECTIVE, REPLACE IT PROMPTLY. REPLACE BURLAP EVERY 60 DAYS.
2. REMOVE SEDIMENT DEPOSITS AS NECESSARY TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE
NEXT RAIN AND TO REDUCE PRESSURE ON THE FENCE. TAKE CARE TO AVOID UNDERMINING THE
FENCE DURING CLEANOUT. REMOVE ALL FENCING MATERIALS AND UNSTABILIZED SEDIMENT DEPOSITS.
BRING THE AREA TO GRADE AND STABILIZE IT AFTER THE CONTRIBUTING DRAINAGE:' AREA HAS BEEN
PROPERLY STABILIZED.
