2.0

3.0    EXISTING CONDITIONS

The subject site is currently undeveloped other than remnant hardstand and
sediment basin areas left after construction of previous stages.

The site falls at moderate grades away from a ridge near Serenity Close
towards Ecological Restoration areas to the west.

Other than one large gum tree the site generally supports only grasses and
small sucker regrowth. A number of smaller trees surround the site’s
perimeter. Trees which need to be retained have been indicated by the
landscape architect and will be appropriately protected as per arborist’s
instructions.

The entire site consists of loose, poorly graded dunal sand and as such
contains no overland drainage paths since rainwater infiltrates directly
through the permeable surface.

Refer detail survey at Appendix E.

4.0    PROPOSED DEVELOPMENT

The proposed development is to consist of two (2) multi storey residential
buildings with basement carparking under each and shared driveway
arrangements. Each building is to be surrounded by extensive terraced
landscape areas, both hard and soft.

For the purpose of engineering design, the buildings are referred to as stages
4A and 4B although it is intended that they will be constructed essentially in
one continuous process with Building 4A to be handed over whilst 4B is
completed.


5.0    STORMWATER TREATMENT & DISPOSAL

Treatment and disposal of runoff will be carried out in accordance with the
approved document Settlers Cove Noosa Residential High Density Environmental
Management Plan (EMP 1) by WBM Oceanics Australia.

This approach will see stormwater runoff from roofs and hardstand areas
infiltrated into the natural sands via a series of Rapid Infiltration Pits (RIPs) in
order to achieve no net reduction in rainwater infiltrating the sand dunes
beneath the site.
