          4.2.2 Operational Maintenance
Periodic maintenance and monitoring of the bioretention area proposed for this development shall
be carried out to ensure it is operating effectively during the operational phase. The responsibility
for these maintenance activities shall be the body corporate or owner of the site.

The bioretention areas shall be maintained following a schedule of routine inspections undertaken
after every significant rainfall event (30mm of rainfall in a 24-hour period) or on a three-monthly
basis within the first twelve months and on a six-monthly basis thereafter. The inspection shall
ensure the proper functioning and condition of the bioretention area and ensure that the planting
and vegetation health is suitably maintained. An inspection checklist from the Healthy Waterways
Technical Design Guidelines for Southeast Queensland has been provided in Appendix C
Bioretention Inspection Checklist that provides the structure for the inspections to be undertaken.

In addition to regular inspections, the first 4 months of establishment of the bioretention areas
requires a watering frequency of:

    i.    Week 1 - 6: 5 times per week


   ii.    Week 6-10: 3 times per week


  iii.    Week 11-15: 2 times per week


After 5 months, watering frequency shall be adjusted based on the local conditions to ensure plants
are maintained in a healthy state.
