nportant operation and maintenance procedures:
- The drainage area will be managed to reduce the sediment load to the dry pond.
- Immediately after the dry pond is established, the vegetation will be watered twice weekly if needed until
the plants become established (commonly six weeks).
- After the initial fertilization to establish vegetation in the dry pond, fertilizer will not be applied to the dry
pond.
- The vegetation in and around the basin will be maintained at a height of approximately six inches.
- At least once annually, a dam safety expert will inspect the embankment. Any problems that are found
will be repaired immediately.
After the dry pond is established, it shall be inspected quarterly 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.
