         Vegetation maintenance will include:
                Fertilising plants;
                Removal of noxious plants or weeds; and
                Re-establishment of plants that die.

         Sediments accumulated at the inlets need to be monitored. Depending on the catchment activities
         the deposition of sediment can tend to smother plants and reduce the ponding volume available.
         Should excessive sediment build-up it will impact on the plant health and require removal before it
         reduces the infiltration rate of the filter media. The proposed SQIDs will require regular maintenance
         and monitoring to ensure that they function as designed.

6.2      Permeable Pavement Maintenance
         Sediment accumulated over the permeable pavement needs to be monitored to ensure the
         permeability of the pavement is not reduced. The proposed SQIDs will require regular maintenance
         and monitoring to ensure that they function as designed.
