                     e. The finished surface levels of the swale alongside the western property boundary must be
                        such that all flows within the swale drain to the bioretention basin as per the MUSIC model
                        provided to Council on 7 November 2018.
                     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 Water by Design maintaining vegetated stormwater assets guidelines.
                        Records of all maintenance activities undertaken must be kept for 5 years and made
                        available to Council upon request.
                     h. 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 at the Pre-Start meet
                     i.    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.
                          Water Sensitive Design
               70.        Prior to release commencement of use, the supervising RPEQ must certify must certify that
                          all hardstand areas of the development drain to a bioretention device designed and
                          constructed in accordance with all relevant conditions of this approval, the Water by Design
                          Bioretention Technical Design Guidelines, relevant aspects of the IPWEAQ Standard
                          Drawing WSUD-drawing series and Construction and Establishment Guidelines: Swales,
                          Bioretention Systems and Wetlands (Water by Design, 2009).
               71.        During construction and establishment of the bioretention devices, the supervising RPEQ
                          must certify forms contained in section 3.15 of the Construction and Establishment
                          Guidelines: Swales, Bioretention Systems and Wetlands (Water by Design, 2009). These
                          forms and certification must be submitted to council prior to the sealing of the survey plan.
               72.        The active filter media of the bioretention device must be as detailed inThe Stormwater
                          Management Report for Lot 5 Taylor Court, Cooroy Qld, 4563 report No 18-0165D Dated 7
                          November 2018 by HR Design . Active filter media area is the area of the bioretention basin
                          surface that is not covered by any impermeable structure such as a sediment forebay, riser,
                          etc.
