SUPERSEDED - Change to an Existing Approval (Construction Staging Plan) [As Published] · 132003.221132.7

                                                                                     2003/221132

       Plan:
       Pages referring to    Correct pages 4, 8, 11, 19, 23, 24, 25, 26, 30 and 33 in accordance
       the Fire              with the conditions of approval for the Fire Management Plan.
       Management Plan:
Sediment and Erosion Control
45.   Detailed staged Sediment and Erosion Control Plans are to be prepared for the site and shall
      be prepared to the reasonable satisfaction of Council and in accordance with the Institution of
      Engineers Australia ‘Engineering Guidelines for Queensland Soil and Sediment Control’ (June
      1996) and in particular using Checklist No. 3 from that document. The sediment and erosion
      control plans shall cover all development on site (during the construction, establishment and
      operational phases) including rehabilitation and remediation.
46.   The Sediment and Erosion Control Plans will deal with the staging of the development
      generally in accordance with WBM’s Report ‘Lensworth Lake Doonella – Stormwater and
      Water Quality Management Plan – Version 2, Revision 3’ of 30/3/03.
47.   The Sediment and Erosion Control Plans shall also include the Public Open Space area and
      shall:
      47.1. Identify existing erosion problems, and
      47.2. Specify appropriate remedial treatments.
48.   The residential precincts shall be designed to incorporate, within their boundaries all the
      necessary sediment and erosion control devices.
Stormwater Management Plan
49.   A Stormwater Management Plan for the site including revegetation and remediation of all
      water treatment areas including swales and bioretention systems shall be prepared to the
      reasonable satisfaction of Council. The Stormwater Management Plan shall be generally in
      accordance with WBM’s Report of 30/3/03.
50.   The developer shall comply with the Stormwater Management Plan and the operational stage
      components of the Stormwater Management Plan shall be referenced in the community
      management statements for all group housing developments over the site.
51.   Key water quality objectives to be reflected in the Stormwater Management Plan are the
      protection of aquatic ecosystems in the site gullies, Cranks Creek and the eastern creek and
      within the receiving waters of Lake Doonella and the Noosa River, as well as primary contact
      recreational standards within the receiving waters. Appropriate water quality standards to be
      adopted are those as specified by Brisbane City Council (in conjunction with the South East
      Queensland Regional Water Quality Management Strategy).
52.   Stormwater Management - MUSIC modelling; Prior to the completion of the final stormwater
      management plan and the civil design drawings for operational works, any stormwater
      management assessments utilising the CRC for catchment hydrology's MUSIC modelling
      system must be corrected for a possible error in the assessment of bio-retention system
      efficiencies and performance in removal of nutrients, as recently notified by the CRC.
      Empirical calculations such as the Brisbane City Council spreadsheet method shall be use to
      adjust the MUSIC model and to demonstrate that realistic removal efficiencies are being used.
      Alternatively, once a 'patch' is available from the CRC, this corrected version of the software
      can be used, but, again, cross checking with empirical calculations is required. The error in
      the bioretention routine will result in the need for additional water quality treatment measures.
      Initial assessments indicate that MUSIC is over predicting removal by as much as twice what
      should be occurring.’
