DESCRIPTION: A FILTER FENCE IS A VERTICAL BARRIER CONSTRUCTED FROM GEOTEXTILE. THE GEOTEXTILE IS TYPICALLY SUPPORTED

BY A WOVEN WIRE FENCE.

CONSTRUCTION: FILTER FENCES SHALL BE INSTALLED PRIOR TO DISTURBING AREAS REQUIRING THE BMP OR AS SLOPE GRADES ARE

ACHIEVED. THE FILTER FENCE SHALL BE BUILT ALONG THE TERRAIN CONTOUR SO THAT WATER IS FILTERED UNIFORMLY ALONG THE

FENCE. INSTALLATION SHALL BE IN ACCORDANCE WITH THE MANUFACTURER'S RECOMMENDATIONS, IN DITCHES OR SWALES, THE FENCE

SHALL CURVE UPSTREAM AT THE ENDS TO PREVENT FLOW FROM BY-PASSING THE FENCE. FILTER FENCES SHALL NOT BE PLACED IN LIVE

STREAMS. THE FENCES SHALL BE POSITIONED TO PREVENT SEDIMENT FROM ENTERING DRAINAGES.

MAINTENANCE AND MONITORING: INSPECT THE FILTER FENCE AT LEAST ONCE EVERY SEVEN CALENDAR DAYS AND WITHIN 24 HOURS

AFTER EACH RUNOFF PRODUCING RAINFALL EVENT. ONE INSPECTION SHALL OCCUR DURING THE FIRST RUNOFF PRODUCING EVENT TO

ASSURE PROPER FUNCTIONING. REPAIR OR REPLACE IF NECESSARY. SEDIMENT MUST BE REMOVED WHEN IT REACHES ONE THIRD THE

HEIGHT OF THE FENCE. REMOVE OR GRADE AND SEED SEDIMENT DEPOSITS BEFORE REMOVING THE FENCE. FILTER FENCES SHALL BE

REMOVED BY OTHERS AFTER FINAL SITE STABILIZATION IS ACHIEVED.

NOTES:

1. A GRANULAR ROCK CHECK DAM IS A SMALL DEVICE CONSTRUCTED OF GRANULAR ROCK MEETING THE GRADATIONS OF

TABLE 703-12 AND PLACED ACROSS A NATURAL OR MAN-MADE CHANNEL OR DRAINAGE DITCH. GRANULAR ROCK CHECK

DAMS REDUCE SCOUR AND CHANNEL EROSION BY REDUCING FLOW VELOCITIES AND ENCOURAGING SEDIMENT DROPOUT.

2. PLACE GRANULAR ROCK CHECK DAMS AS LOCATED AND APPROVED BY CO. EACH GRANULAR ROCK CHECK DAM IS

APPROXIMATELY 1.5 CY.

3. REMOVE SEDIMENT FROM BEHIND THE DAM WHEN IT ACCUMULATES TO ONE-HALF THE ORIGINAL HEIGHT UNLESS ITS

DRAINAGE AREA HAS BEEN STABILIZED.

4. SEDIMENT TRAPS SHALL BE CONSTRUCTED BELOW GRADE WHERE POSSIBLE. AT LOCATIONS WHERE BEDROCK PREVENTS

INSTALLATION OF SEDIMENT TRAPS TO THE PRESCRIBED DEPTH, CONSTRUCT SEDIMENT TRAPS ABOVE GRADE TO ACHIEVE

RECOMMENDED DIMENSIONS.

5. TOP OF SEDIMENT TRAP OUTLET SHOULD NOT BE BELOW THE EXISTING GROUND ELEVATION.
