Decision Notice - Change to an Existing Approval - 010.2006.00000823.003 [As Published] · 132006.823.03

                                                                                        2006/823

205. Roof runoff from any of the villas and other central buildings shall be directed to a rainwater
     storage system or tank (minimum storage 3000 litres per villa and for other uses minimum
                                          2
     storage calculated using 12 litres/m of roof area) that is installed to ensure water from the
     tank can be used for external uses (such as watering gardens, irrigation, ornamental ponds,
     water features, topping-up swimming pools, outdoor cleaning, etc) and for use in flushing of
     toilets internal to the dwellings and buildings. All rainwater tanks are to be designed and
     installed in accordance with the Queensland Development Code (QDC), Part 25 – Rainwater
     Tanks, and shall be part of the plumbing application in conjunction with the building approval.
     The location and capacity of the tanks shall be clearly shown on the plans submitted for
     Building Works approval and any overflow shall be directed to the stormwater drainage
     system.
206. The applicant shall submit an analysis of water supply reliability for internal reuse of collected
     rainwater on the site with an application for Plumbing Works. This shall assess the
     requirements for dual plumbing to enable rainwater to be used for toilet flushing.
207. To ensure that polluted run-off does not enter the Noosa River, stormwater run-off from the
     carparking areas and the driveways shall have the first flush (the first 12 mm of rainfall or
     hose-down) collected in a grease/oil arrestor provided on site prior to being permitted to
     discharge into Council’s drainage system.
      All other clean stormwater, such as roof water, can be collected on site and discharged
      through a single underground drain line directly into the existing drainage system, bypassing
      the grease/oil arrestor.
      To this end, a detailed maintenance plan shall be prepared for the proposed grease/oil
      arrestors, which shall be submitted to the Council for approval prior to obtaining a
      Development Permit for Operational Works.
      The approved maintenance plan shall be incorporated in the Community Management
      Scheme for the development and a copy of this shall be provided for Council’s records prior to
      commencement of the approved Use.
      A Development Permit for Building Works shall not be granted until a Development Permit for
      Operational Works has been issued in regard to the drainage scheme.
208. All site stormwater drainage shall be by means of a gravity system.
209. All stormwater drainage lines including inter-allotment drainage shall be inspected by closed
     circuit television (CCTV) prior to commencement of the approved Use.
      CCTV inspection will be carried out by Council's CCTV contractor and arranged by Council
      following satisfactory completion of construction works. The developer will be responsible for
      the full cost of CCTV inspection, including any additional inspection necessary following defect
      identification and rectification. This charge is payable prior to the issue of Operational Works
      approval and will be determined on the unit rate basis current at the time of approval.
Stormwater Management Plan
210. A Stormwater Management Plan generally in accordance with the “Viridian Noosa Hydrology
     and Stormwater Management Plan” dated 30 August 2006 and prepared by WBM Pty Ltd
     shall be submitted in conjunction with any Operational Works Applications for the site.
      The plan shall include details of an appropriate stormwater treatment system to achieve the
      water quality objectives and shall provide plans showing that all works are located outside the
      10 metre buffer to the intermittent creek.
      The Developer shall not commence any development on Site until the Manager – Land
      Development, approves the Stormwater Management Plan. The Developer may amend the
      stormwater management plans only with the prior written approval of the Manager – Land
      Development, which is not to be unreasonably withheld.
