NOOSA COUNCIL IDAS Development Application Decision Notice                                                  6 of 16


Roof Water & Stormwater Drainage
38.    Roof runoff from any new building shall be directed to a rainwater storage system or tank (minimum
                                                                                              2
       storage 3000 litres per dwelling/unit and the greater of 5000 litres or 15 litres/m of roof area for
       commercial uses) that is installed to ensure water from the tank is 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 building. 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 /
       Operational Works approval and any overflow shall be directed to the stormwater drainage system.

39.    All stormwater drainage (including roof water overflow from the rainwater storage system) shall be
       collected 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 existing drainage structures in
       Hastings 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.

40.    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.
41.    All site stormwater drainage shall be by means of a gravity system.

42.    All stormwater drainage lines including drainage within Hastings Street 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.
Sewer Mains
43.    The property shall be connected to the existing house connection branch (HCB) located in south-eastern
       corner of the property. Internal sewer drains are to be configured to provide for gravity flow to existing
       connection point. Connection to the sewer at rear will not be permitted.

44.    The existing sewer and connection to the rear (northern boundary) shall be capped and abandoned by
       Council at Applicant’s expense at the time of demolition of existing structures on the site. The applicants
       and/or their contractor shall contact Council to arrange for capping and abandonment of the existing
       sewer. The cost of these works shall be advised at the time of application for the works.

45.    The existing sewer main that traverses the site adjacent to the northern boundary and the ‘zone of
       influence’ (taken as the area within a 45-degree angle measured from the invert of the sewer main to the
       finished surface level) shall be accurately located and determined by a licensed Surveyor and shown on
       all plans submitted for Operational Works approval.
     To ensure Council’s sewer main is accessible for maintenance purposes and is protected from risk of
     damage no structures requiring a building permit (eg. buildings, swimming pools, retaining walls
     exceeding 1m in height, raised terraces, etc) shall be constructed within this ‘zone of influence’ or within
     1.5m of the centreline of the sewer main, whichever is the greater. As such the applicant shall amend
     Operational Works plans including Building plans to ensure compliance.
Town Water Supply
46.    The site shall be connected to Council’s existing town water supply and be constructed in accordance with
       Council’s standards and requirements at no cost to Council.
