OPERATIONAL PHASE                                                                                            5-6
        of the swales as this will impact upon their water quality improvement function. Photographs of
        swale elements requiring remediation should be taken prior to and following corrective actions.

        Maintenance of subsurface drainage shall be in accordance with stormwater management guidelines
        as described in the EMP.

        The above swale maintenance regime is to be conducted during the first two years during plant
        establishment. Swale maintenance for 12 months after practical completion and on-maintenance
        certification shall be the responsibility of the developer. Thereafter on-going maintenance (following
        successful off-maintenance certification by council) will be the responsibility of council.

        Following the 2 year establishment period, monitoring and maintenance visits can be reduced to
        every 2 months during summer and spring and 3 monthly during the cooler autumn and winter
        periods, although mowing of grassed sections shall still follow the establishment period regime.
        Inspections shall also continue to follow heavy rains.

        Refer to Maintenance Regime table below.
