          65.2. a contingency plan to monitor for and to remove cyanobacterial and algal
                outbreaks from waterbodies, including costs, is provided for approval with the
                Operational Works application and the approved version is implemented
                throughout the lifetime of the development. All stormwater runoff treatment
                must be undertaken within the development areas of the site. Stormwater likely
                to contain grease and oil (i.e. from all roads and car parking areas) shall be
                managed via grease and oil arrestors prior to treatment within bioretention
                basins, wetlands and water quality control ponds.
    66.   Wetlands, bioretention basins and other water quality treatment devices shall be
          designed and constructed in accordance with Healthy Waterways Water Sensitive
          Urban Design – Technical Guidelines for South East Queensland 2006, Water by
          Design Bioretention Technical Design Guidelines 2014, Healthy Waterways Water by
          Design Construction and Establishment Guidelines: Swales, Bioretention Systems
          and Wetlands February 2009. In the case of any inconsistencies between these
          documents, the most recent document shall prevail.
    67.   Stormwater treatment strategy must be designed and maintained to achieve
          compliance with the approved version of B14158.W.07L.AMcP.ag.docx dated 8
          October for the Stormwater Management Construction and Maintenance Plan
          Framework.
    68.   The detailed Stormwater Management Construction and Maintenance Plan (SMCMP)
          must be designed and implemented in accordance with the framework detailed in the
          approved version of B14158.W.07L.AMcP.ag.docx dated 8 October and approved by
          the Council prior to issue of operational works approval:
    69.   The owner of the development is responsible for all costs associated with the
          construction and ongoing maintenance and repair of the treatment of stormwater on
          the site and for all catchments that enter the site.
    70.   The Operational Works Application must include calculations in accordance with the
          Queensland Urban Drainage Manual to demonstrate that the confluence of
          stormwater at the drainage easement will not cause scour and that any required
          dissipater/erosion control can be contained wholly within the applicant’s property.
    71.   Any waters captured on site must be plumbed to be available for all external uses
          including gardening, irrigation, filling swimming pools and outdoor cleaning, as well as
          all ground floor toilet cisterns and washing machine cold taps.
    72.   Operational Works Application must demonstrate that the peak 1-year ARI event
          discharge off site is limited to the pre-development peak 1-year ARI event discharge
          flow.
    73.   Prior to commencement of use, the applicant must provide Council with a
          performance bond to the value of 150% of the value of monitoring and maintenance
          of the water bodies for the first 5 years of full operation. The bonds shall
          be incrementally released annually following completion of the development
          and upon demonstration to the satisfaction of Council Officers that all aspects of the
          approved version of the detailed Stormwater Management Construction and
          Maintenance Plan required by this approval have been implemented to effectively
          prevent or reduce likelihood of cyanobacteria outbreaks for the site for the preceding
          year.
    Water & Sewer Connections
    74.   An underground connection to reticulated water and sewerage must be provided to
          the development site in accordance with the standards and requirements of Northern
          SEQ Distributor–Retailer Authority (Unitywater).
