Infiltration Basin Maintenance Requirements
Important operation and maintenance procedures:
- The drainage area will be carefully managed to reduce the sediment load to the infiltration basin.
No portion of the infiltration basin will be fertilized after the initial fertilization that is required tc
- 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.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.
