Plan View
Maintenance Inspect rock doughnut inlet protection at least weekly and after each significant
(A inch or greater) rainfall event and repair immediately.
To provide satisfactory inlet protection efficiency, remove sediment fiom
the sediment pool area when the volume is decreased by half. This will
help provide adequate storage volume for the next rain. Stabilize excavated
material appropriately.
Take care not to damage or undercut the structure during sediment removal.
Remove debris from the inlet and replace stone as needed. If the inlet was
covered with wire mesh the mesh should be cleaned of debris.
When the contributing drainage area has been adequately stabilized, remove
all materials and dispose of sediment properly. Bring the disturbed area to the
grade of the drop inlet, Smooth and compact it as needed.
Appropriately stabilize all bare areas around the inlet with ground cover.
