1,1. WERE CONCENTRATED RUNOFF FROM DtSTURBED AREAS TO AND FROM PONDS OR TRAPS.
12. TO CONVEY RUNOFF INTERCEPTED FROM UNDISTURBED AREAS AROUND THE SITE TO A NON -EROSIVE DISCHARGE POINT.
2- MAINTENANCE STANDARDS
2.1. ANY SEDIMENT DEPOSITION OF MORE THAN 0.5 FEET SHALL BE REMOVED SO THAT THE CHANNEL IS RESTORED TO ITS ORIGINAL
DESIGN CAPACITY.
22. THE CHECK DAMS SHALL BE EXAMINED FOR SIGNS OF SCOURING AND EROSION OF THE BED AND BANKS. IF SCOURING AND EROSION
HAS OCCURRED, AFFECTED AREAS SHALL BE PROTECTED BY RIPRAP OR AN EROSION CONTROL BLANKET.

22. STANDARD STRENGTH FABRIC REQUIRES WIRE BACKING TO INCREASE THE STRENGTH OF THE FENCE. WIRE BACKING OR CLOSER PORT
SPACING MAY BE REQUIRED FOR EXTRA STRENGTH FABRIC IF FIELD PERFORMANCE WARRANTS A STRONGER FENCE.
23. VIMERE THE FENCE IS INSTALLED, THE SLOPE SHALL NOT BE STEEPER THAN 2HAV
24. IF A TYPICAL SILT FENCE IS USED, THE STANDARD 4X4 TRENCH MAY NOT BE REDUCED AS LONG AS THE BOTTOM 8 INCHES OF THE SILT FENCE
IS WELL BURIED AND SECURE IN A TRENCH THAT STABILIZES THE FENCE AND DOES NOT ALLOW WATER TO BYPASS OR UNDERMINE THE SILT
FENCE.
3. N AMTEMANCE STANDARDS
3.1. ANY DAMAGE SHALL BE REPAIR IMMEDIATELY.
3.2. IF CONCENTRATED FLOES ARE EVIDENT UPHILL OD THE FENCE, THEY MUST BE INTERCEPTED AND CONVEYED TO A SEDIMENT TRAP OR POND,
3.8. IT IS IMPORTANT TO CHECK THE UPHILL SIDE OF THE FENCE FOR SIGNS OF THE FENCE CLOGGING AND ACTING AS A BARRIER TO FLOW AND
THEN CAUSING CHANNELIZATION OF FLOWS PARALLEL TO THE FENCE. IF THIS OCCURS, REPLACE THE FENCE OR REMOVED THE TRAP
SEDIMENT.
&C SEDIMENT MOST BE REMOVED WIEN SEDIMENT 15 6 INCHES HIGH.
3.5. IF THE FILTER FABRIC (GEEQTEXTILE) HAS DETERIORATED DUE TO LILTRAVIOLET BREAKDOWN, IT SHALL BE REPLACED.
