        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. Should excessive
        sediment build-up it will reduce the permeability of the pavers, thereby inhibiting filtration through
        the pavers. The proposed SQIDs will require regular maintenance and monitoring to ensure that they
        function as designed.
