Infiltration Basin Maintenance Requirements
Important operation and maintenance procedures
The drainage area will be carefully managed to reduce the sediment load to the infiltration b 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.
- The vegetation in and around the basin will be maintained at a height of four to six inches.
After the infiltration basin is established, it will 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
ection activities shall be performed as follows. Any problems that are found shall be repaired immediately.
