NOOSA COUNCIL IDAS Development Application Decision Notice 6 of 12

Earthworks

31.

Should filling works be required for building footprints then they shall be carried out in accordance with
Section 3.8 of Council’s Engineering Design Standards Manual and so as not to cause the additional
ponding of water on any adjoining lands or the blockage of, or interference with, any natural watercourses.
Detailed site surveys indicating natural surface levels and contours of the adjoining properties must be
provided with the application for a Development Permit for Operational Works for Filling and Drainage.

This may require the design and construction of drainage pipes and/or an overland flow-path within the
development site that caters for drainage from the adjoining sites for a design storm with an Average
Recurrence Interval of 1 in 100 years. A private easement for the Drainage of Water encompassing the
drainage pipes or overland flow-path will also be required. In this regard a Development Permit for
Operational Works shall be obtained.

Should evidence be provided to Council indicating that no additional ponding of stormwater will occur on
the adjoining properties the requirement for the drainage pipes, overland flow-path and easement shall
not apply.

Acid Sulfate Soils

32.

As the site is located below the 20m AHD and above the 5m AHD, any excavation works consisting of
100m* or greater which extends below 5m AHD will need to be carried out in accordance with State
Planning Policy 2/02 Planning and Managing Development Involving Acid Sulfate Soils. In this regard
appropriate testing and supporting documentation prepared by a suitably qualified specialist shall be

submitted to Council for approval prior to obtaining a Development Permit for Operational Works.

Erosion and Sediment Control

33.

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.

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.

40.

A suitably qualified Registered Professional Engineer shall prepare engineering drawings and
specifications for all engineering works that will become Council infrastructure, which shall be submitted in
conjunction with an application for a Development Permit for Operational Works. In this regard a
DXF/DWG file on GDA94 zone 56 grid of the proposed cadastre layout is to be submitted in conjunction
with any application for Operational Works.

Digital detailed design drawings and calculations shall be submitted with any application for a
Development Permit for Operational Works in respect of roadworks and stormwater drainage works. The
design shall be in accordance with Council's Planning Scheme Policy PSP05 — Engineering Design
Standards — Roads, Drainage and Earthworks. To avoid conflict with underground pipes or services, all
existing and proposed services required by the development shall be shown on the plans.

To facilitate production of As Constructed drawings it is suggested that all design drawings are submitted
in the Asset Design and As Constructed (ADAC) digital format. (Guidelines on the use of ADAC are
available at www.adac.com.au).

Any damage caused to any public utility during the course of construction shall be repaired to Council's
standards and at no cost to Council.

Any alteration of any public utility or other facilities necessitated by the development of the land or
associated construction works external to the site shall be at no cost to Council.

The transportation of all materials to and from the site shall be undertaken in a manner such that no
particle matter escapes onto a public road. All vehicles carrying materials either to or from the site shall
be covered to prevent materials including dust being windblown from the vehicle.

As Constructed drawings and data shall be certified by a qualified experienced Civil Engineer for design
intent, and a Licensed Surveyor shall certify the cadastre and the location, level and type of all services
and structures. All of which shall be submitted to Council for checking and for Council’s records.

The data must fully detail levels for all engineering works including but not limited to drainage structures,
finished ground levels and pavement surface levels. The data shall be submitted in the Asset Design and
As Constructed (ADAC) digital format. (Guidelines on the use of ADAC are available at
www.adac.com.au).
