Installation of silt fence

• Break the slop up into individual bays to capture the overland
flow

• Ensure that the bays have sufficient curvature to prevent the flow

escaping around the side

• Insert the bottom part of the fence within a backfilled trench to
prevent water passing underneath the silt fence

• The number of bays required will be depends on the steepness of

the slope, the area drained, the amount of rainfall

• Periodically remove the sediment that has built up in front of the
fence

• Following a major storm event inspect the silt fence for damage
and replace as necessary
