SILT FENCE CONSISTS OF WOVEN WIRE FENCE FABRIC WITH A MAXIMUM 6 INCHES MESH, MINIMUM HEIGHT

THE CO MAY REQUIRE ADJUSTMENTS TO ACTUAL LENGTHS OR LOCATIONS TO FIT FIELD CONDITIONS.

INSPECT SILT FENCES AFTER EACH RUNOFF EVENT AND IMMEDIATELY REPAIR ALL EROSION ALONG EDGES

ACCUMULATED DEPTH OF SEDIMENT SHALL NOT EXCEED ONE HALF THE ORIGINAL HEIGHT OF THE SILT FENCE.

IN AREAS DESIGNATED FOR BRUSH BARRIERS, LIMIT CLEARING TO TREES, SHRUBS AND PLANTS LESS THAN 4

INCHES IN DIAMETER. GRUBBING SHALL NOT BE PERFORMED IN THESE AREAS.

BRUSH BARIER SHALL BE CONSTRUCTED APPROX. PARALLEL TO ORIGINAL GROUND CONTOUR. USE WELL-INTERMINGLED MASS OF BRUSH, TREES, TRIMMINGS, ETC. BARRIER SHALL BE POROUS ENOUGH TO ALLOW WATER TO FILTER THROUGH. SECURE BY PLACING HEAVIER MATERIAL (TREES, LOGS, ETC.) ON TOP

OF AND THROUGHOUT THE BRUSH.
