sediment prior to. discharge into a storm water drainage system or watercourse.
Inlet protective devices shall b'e used on construction projects where sediment laden
surface runoff may enter an inlet, or where disturbed drainage areas have not been
permanently stabilized, and where pounding will not encroach into roadways.
Use only when po .unding will not encroach into.traffic or onto erodible surfaces
and slopes. 'If safety is a concern, use other methods of temporary protection to
prevent sediment-laden storm water and non-storm water discharges from
entering the storm drain system.
Gravelbag Barrier
Gravelbag barriers for inlet protection are appropriate for sheet flows and
concentrated flows exceed 0.5 cfs and where overtopping may be necessary to
prevent flooding.
Place bags in a minimum two-high layer on the upstream flow path.
Insure that flows from a severe storm shall not overtop the curb.

· Key-in the bottom of the filter fabric.
· Make sure the stakes are securely driven in the ground and in good shape, replace
damaged stakes as necessary.
· Replace or clean the 'fabric when it'becomes clogged with sediment. Make sure
the fabric does not have any holes or tears, repair or replace fabric as necessary.
· Remove the sediment from behind the fabric fence when accumulation reaches
one-third the height of the fence.

Excavated drop inlet sediment traps are appropriate where relatively heavy flows
are 'expected and' overflow capacity is needed, in cleared and grubbed and graded
areas.
· Piaee filter 'fabric fence aroUnd excavated basin.

of 67yd3/ac of drainage area.
Page 1 of 2
· Shape basins so that the longest inflow arcs faces the longest length of the trap.
· For concentrated flows, shape basin in a 2:1 ratio with length oriented towards
direction of flow.
· Remove sediment from the basin when it the volume of the basin has reduced by
half.
· Install a stabilized conveyance for concentrated flows to reduce scour and erosion.
Maintenance and Inspection:
· Inspect all inlet protection devices before and after every rainfall 'event, and
weekly during the rest of the season.

protection is no longer needed.
· Clean and re-grade area around inlet, clean sediment and/or debris from inside the
inlet after removal.
