5.0 MAINTENANCE PERIOD
The proposed bioretention basins will be installed at the end of the building construction phase when
the site is stabilised.
5.1     Maintenance During ‘Construction Period’
Erosion and sediment control devices will be installed at the commencement of the works to capture
and treat runoff during construction works. The sediment control devices should be cleaned out as
required and at the end of the works. During the construction stage, all sediment control devices
are to be inspected weekly, after runoff generating rain events and prior and after prolonged site
shut downs (e.g. holiday periods).
5.2     Maintenance During ‘Maintenance Period’
In order to establish vegetation and treatment functions in bioretention systems, the filter media must
be protected from pollutants commonly generated in the construction phases. It is therefore
recommended that the filter media be protected via geofabric and turf during construction. Upon
completion of the construction phase, the protective measures can be removed. During the
operational phase, regular maintenance of the bioretention system is required to ensure
comprehensive vegetation establishment, a critical component in stormwater pollutant uptake.
6.0 CONCLUSIONS AND RECOMMENDATIONS
This SMP has provided detail regarding the proposed stormwater treatment strategy for the
Essence of Peregian development. The strategy makes use of bioretention basins to treat surface
runoff prior to discharge to the Council Reserve to the west of the site. The proposed strategy
achieves the required pollutant reduction targets required by NSC and the SPP (2016).
