Infiltration Basin Maintenance Requirements
Important operation and maintenance procedu
- The drainage area will be carefully managed to reduce the sediment load to the infiltr
No portion of the infiltration basin will be fertilized after the initial fertilization that is
- required to establish the vegetation. Lime may be allowed if vegetation is planted on
the surface of the infiltration basin and a soil test shows that it is needed.

Wet Pond Maintenance Requirements
Important operation and maintenance procedures:
Immediately after the w et detention basin is established, the plants on the vegetated shelf and
- perimeter of the basin should be w atered tw ice weekly if needed, until the plants become
established (corruunly six weeks).
No portion of the wet pond should be fertilized after the initial fertilization that is required to
establish the plants on the vegetated shelf.
Stable groundcover w ill be maintained in the drainage area to reduce the sediment load to the w et
pond.
If the pond must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain w ill be minimized as much as possible.
At least once annually, a dam safety expert w ill inspect the embankment. Any problems that are
found w ill be repaired immediately.
The measuring device used to determine the sediment elevation shall be such that it w ill give an
accurate depth reading and not readily penetrate into accumulated sediments.
After the wet pond is established, it w ill be inspected quarterly and within 24 hours after every storm event
