PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                                        6 APRIL 2021


    42.   All earthworks and associated retaining structures/batters/anchors must be contained
          entirely within the subject site unless written permission from the respective landowner(s)
          is provided to Council. All earthworks must be undertaken in accordance with the
          provisions of Australian Standard AS3798: Guidelines on Earthworks for Commercial
          and Residential Developments.
    43.   Where the development involves excavation or filling over, or adjacent to, drainage,
          water supply or sewerage infrastructure, all access chamber surface levels must be
          adjusted to provide a freeboard of 100mm above the finished ground surface level.
    44.   All retaining walls must be designed and constructed in accordance with the planning
          scheme and must be certified by an RPEQ where exceeding 1.0m in height. All retaining
          walls that are publicly accessible and exceed 1.0m in height must be fitted with a
          commercial grade safety fence.
          Damage to Services and Assets
    45.   Any damage caused to existing services and assets as a result of the development works
          must be repaired at no cost to the asset owner at the following times:
          a.    where the damage would cause a hazard to pedestrian or vehicle safety,
                immediately; or
          b.    where otherwise, upon completion of the works associated with the development.
          Any repair work which proposes to alter the alignment or level of existing services and
          assets must first be referred to the relevant service authority for approval.
          Stormwater Quality
    46.   The development must include a stormwater quality treatment system designed to
          achieve 80% reduction in Total Suspended Solids, 60% reduction in Total Phosphorous,
          and 45% reduction in Total Nitrogen compared to an unmitigated scenario, prior to
          discharge from the site.
    47.   The stormwater quality treatment system must be in accordance with an Operational
          Works approval for stormwater drainage and, the Queensland Urban Drainage Manual.
          The application for Operational Works Approval must demonstrate that:
          47.1. all runoff can be filtered via vegetated areas prior to discharge from the site.
          47.2. pollutant reduction predicted for the stormwater quality treatment train is designed
                in accordance with the Water by Design MUSIC modelling guidelines (Version 1)
                2010.
          47.3. Detail design plans for the stormwater treatment train, and submitted for the
                Operational Works approval, demonstrate the size of water quality improvement
                features are consistent with the MUSIC model, and are visually integrated into the
                development in accordance with the Water by Design Bio-retention Technical
                Design guidelines (Version 1.1) October 2014.
          47.4. Any necessary retaining walls within bio retention basins must not exceed 0.8m in
                height. The operational works approval application must detail proposed rock
                finishing on any retaining walls, and these approved finishes shall be maintained
                for the life of the development. Raw finished concrete block retaining walls will not
                be approved.
          47.5. The application for operational works approval must include the design for
                educational signage to be included within/alongside the bio-retention basin.
                Signage must follow a green and white colour pallet and state “This bio retention
                basin cleans stormwater runoff prior to its discharge to The Noosa River”.
