                                                                                      Callaghan & Toth

                         should be made for unsuccessful plantings. Ensure watering rates are adequate
                         and increase if necessary.
                         Replace geotextile where used, check and if necessary replace sand media with
                         coarser sand. Check that slotted pipe is not blocked and outlet free draining.
                         Replace and repair where necessary.
                         Erosion should be repaired and investigate measures to reduce erosion e.g.
                         install rock spalls upstream of the erosion so as to dissipate the flow across a
                         broad area.
                         Dominating weeds should be removed by hand and taken to the Council’s Refuse
                         Centre.

                                              Operational Phase

Objective                The Owner is to include the Bioretention systems into their maintenance
                         program.



Actions                  Inspect Bioretention systems every six months to determine maintenance
                         requirements.
                         Undertake general maintenance such as:
                              ¾   Remove accumulated litter / debris
                              ¾   Remove accumulated sediments
                              ¾   Remove weeds and dead plants
                              ¾   Replace plants where necessary
                              ¾   Water plants if necessary
                              ¾   Control erosion and sediment loss upstream or within system where
                                  necessary.
                         Routine clean outs of Bioretention Systems should be planned on a ten-yearly
                         basis.

Monitoring               The Owners Landscape Gardener will carry out six monthly inspections of the
                         Bioretention Systems. The following will be examined at each inspection:
                              ¾   Sediment build up on the surface under the river stones
                              ¾   Health of vegetation
                              ¾   Pondage during major storms not infiltrating into the sand
                              ¾   Erosion at the outlet
                              ¾   Pondage during minor storms

Reporting                Inspection Records are to be logged and kept for verification of compliance on a
                         need basis.
                         Records of any maintenance are to be logged and kept on site.
                         Records of environmental incidents and corrective actions should be kept on site
                         and Council notified of any problems.

Incidents                Sediment builds up on the surface.
                         The vegetation dies off.
