TYPICAL INSTALLATION OF SEDIMENT FENCE
NOT TO SCALE
MAINTENANCE
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.
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 unstable sediment deposits and bring the
area to grade and stabilize it after the contributing drainage area has been
properly stabilized.
MAINTENANCE
Inspect temporary sediment trap at least weekly and after each significant
(1/2 inch or greater) rainfall event and repair immediately. Remove sediment, and
restore the trap to its original dimensions when the sediment has accumulated
to one—half the design depth of the trap. Place the sediment that is removed in
the designated disposal area, and replace the part of the gravel facing that is
impaired by sediment.
Check the structure for damage from erosion or piping.. Periodically check the
depth of the spillway to ensure it is a minimum of 1.5 feet below the low point
of the embankment. Immediately fill any settlement of the embankment to
slightly above design grade.Any rip rap displaced from the spillway must
be replaced immediotely.
After all sediment —producing area has been permanently stabilized, remove
the structure and all unstable sediment. Smooth the area to blend with the
adjoining areas, and stabilize properly.
