Infiltration System Maintenance
Important maintenance procedures:
The drainage area will be carefully managed to reduce The sediment load to The infiltration basin.
Immediately after the infiltration basin is established, the vegetation will be watered twice weekly if needed until
the plants become established (commonly six weeks).
No portion of the infiltration basin will be fertilized after the initial fertilization that is required to establish the
vegetation.
The vegetation in and around the basin will be maintained at a height of approximately six inches.
After the infiltration basin is established, it shall be inspected once a quarter and within 24 hours after every storm event
greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance shall be kept in a known
set location and shall be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.
