NOOSA COUNCIL IDAS Development Application Decision Notice                                                 6 of 18


31.    All site stormwater drainage shall be by means of a gravity system.
Sewer Mains
32.    The site shall be connected to Council’s existing sewerage reticulation systems and be constructed in
       accordance with Council’s standards and requirements at no cost to Council.

33.    All effluent waste flows from the developed site shall be directed to the internal pump well or holding
       tank/s generally in accordance with the Integrated Water Management Plan report dated December 2006
       and Drawing No 1658-2 dated 13 December 2006 by Construction Hydraulic Building Service Engineers.

34.    The sewer pumping system shall have minimum a 12 hour storage capacity between alarm and overflow
       levels. The system is to be connected to a 24 hour monitoring service which is notified in the event of a
       high level alarm. The system shall be designed to ensure that the pressure main has less than a one
       hour detention time to prevent odour production including during occupant absences. A flushing system
       may be required to ensure detention times do not exceed one hour. Engineering plans for the sewer
       layout and the sewer pumping system shall be submitted to Council for approval prior to the Pluming and
       Drainage Application. Any enquires in relation to this matter can be directed to Council’s Sewer Section
       (Tel 54495288).

Earthworks and Site Stability

35.    All civil works on the site shall take into consideration the findings and the recommendations of the
       geotechnical investigation report Project 306-2512 dated December 2006 by Soil Surveys Engineering.

36.    Earthworks required on site shall be undertaken without the use of vibratory equipment and in a manner
       does not compromise the stability of the site or adversely impact on the stormwater drainage pattern and
       be in accordance with the recommendations of the geotechnical investigation report Project 306-2512
       dated December 2006 prepared by Soil Surveys Engineering.

37.    All excavations both temporary and permanent must be adequately retained to prevent the occurrence of
       landslip and the retention works shall be carried under direct guidance and supervision of a geotechnical
       engineer.

38.    Earthworks carried out on site shall not affect the structural integrity of any of the existing fences,
       services, road stability or structures that border the development site. Fences that are affected shall be
       replaced prior to plan endorsement. In this regard any fences to be replaced shall be clearly shown on
       the plans submitted for Operational Works approval.

39.    The footings and foundation works shall be founded to a depth recommended by a geotechnical engineer.
       Any shallow footings or ground bearing slabs design shall address the potential of slope movement in
       detail.

40.    Detailed design engineering plans of the foundation and retention works shall be submitted to Council
       prior to obtaining the Development Permit for Operational Works. The design plans shall be certified by a
       suitably experienced RPEQ.

41.    A Geotechnical Engineer or similar qualified expert shall establish whether any measures are required to
       protect the stability of adjoining buildings and/or structures, and make recommendations on the type of
       foundation system(s) best suited for the proposed development. This information shall be submitted to
       the Council for assessment and approval prior to obtaining a Development Permit for Operational Works.

42.    An existing Conditions Survey is to be carried out on adjoining buildings, structures, fences and
       landscaping prior to any construction works taking place on site. If distress already exists, a photographic
       survey shall be undertaken, the distress measured and a plan to monitor changes to distress shall be
       implemented. A copy of this report is to be submitted to Council within 5 business days of survey and prior
       to construction work proceeding.

Erosion and Sediment Control

43.    Any person acting on this permit shall prevent erosion and sediment export from leaving the site. Site
       control measures such as silt fencing, controlled gravel access to the site and controlled disposal of
       waste, will be necessary. Giving the sensitivity of the site the type of erosion control devices and the
       manner of their installation shall not compromise the integrity of the sand dune and the steep slope.

44.    In this regard plans detailing the methods of controlling erosion and sediment are required to be submitted
       to the Council for approval prior to obtaining a Development Permit for Operational Works.
