SUPERSEDED Decision Notice - Change to an Existing Approval - 010.2005.00001189.004 [As Published] · 132005.1189.04

                                                                                        2005/1189

Stormwater Drainage
43.   All stormwater drainage shall be collected on site and discharged so there is no net increase
      in stormwater runoff from the site. Stormwater drainage permitted to drain from the site shall
      be discharged to Council’s kerb & channel street drainage system in both Gympie Terrace and
      Thomas Street. Plans of the drainage design shall be prepared by a Registered Professional
      Civil Engineer and submitted to Council prior to obtaining a Development Permit for
      Operational Works.
      The maximum discharge of stormwater drainage allowable to Council’s kerb & channel street
      drainage system at any one location is 25 litres/second.
44.   The existing open concrete channel running along the base of the retaining walls of adjoining
      properties on the southern boundary of Lot 2 RP102593 and at the rear boundary of Lots 1&2
      RP102594 and Lot 2 RP102593 shall be replaced by piping to drain any areas of the site or
      adjoining lots that pond due to proposed filling.
45.   Roof runoff from any new dwelling shall be directed to a rainwater storage system or tank
      (minimum storage 3000 litres per dwelling unit) that is plumbed to service the toilets in the new
      dwelling and landscaping areas. The design of the rainwater storage system shall be to the
      satisfaction of the Manager Plumbing Services.
46.   As the site is proposed to be filled, appropriate stormwater drainage pipes shall be installed
      within the site to collect and discharge stormwater runoff from all adjoining properties to
      prevent additional ponding/flooding on these properties.
47.   Drainage of the site shall be in accordance with the principles of Council’s - Noosaville Master
      Drainage Plan to ensure that the site discharges to the appropriate drainage catchments. This
      information can be obtained from Council’s Technical Officer - Development, by contacting
      5449 5263.
48.   To ensure that polluted run-off does not enter Council’s stormwater drainage system,
      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.
49.   All site stormwater drainage shall be by means of a gravity system.
50.   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.
