                                development

            f.   The development must include bins with educational signage material to
                 encourage patrons who purchase items that generate gross pollutants to
                 dispose of such items appropriately, and not where they may enter
                 stormwater systems.
            g.   Stormwater quality treatment devices must be routinely checked, serviced
                 and cleaned in accordance with the manufacturer’s recommendations or
                 Water by Design maintaining vegetated stormwater assets guidelines.
                 Records of all maintenance activities undertaken must be kept and made
                 available to Council upon request. Where replacement cartridges or other
                 necessary components for the system become unavailable, an alternative
                 system is required to be retrofitted into the development to achieve an
                 equivalent pollutant reduction outcome.
            h.   All primary stormwater quality treatment devices must be routinely
                 checked, serviced and cleaned in accordance with the manufacturer’s
                 recommendations. Records of all maintenance activities undertaken must
                 be kept for 5 years and made available to Council upon request.
            i.   The ongoing maintenance plan for the development must include the
                 operations and maintenance manual for the water quality device/s and
                 must include the full cost of maintaining the system. This maintenance plan
                 must be provided as part of the subsequent operational works
            j.   The development must not cause an increase in peak flow runoff in 1, 5,
                 50 or 100 ARI events. The subsequent application for operational works
                 must include calculations and designs to demonstrate how this condition is
                 achieved.
