3.0 SITE DESCRIPTION

The site for the proposed residence is located on the southern side of The Promontory in
Noosa Waters estate, Noosaville and is described as being generally level but with a
sloping section falling towards the Noosa Waters cana! at the rear of the block. At the
time of the investigation fieldwork, the site was occupied by an existing double storey
residence of masonry construction, and the surrounding garden included grass and
small to medium size shrubs, and some ornamental trees. It is understood that the
building is to be demolished.

4.0 GEOTECHNICAL INVESTIGATION
4.1 Field Investigation

Subsurface conditions at the site were investigated by drilling 2 No. boreholes to depths
of 6.0m to 7.5m. Both boreholes were carried out near the front of the property, due to
the restricted access conditions, and a plan showing these locations is included in
Appendix C.

Disturbed samples were taken at 0.25m intervals down to a depth of 3.0m in both
boreholes, for the purposes of acid sulfate soil testing.

The soil classification descriptions and field testing were carried out by Soil Surveys
Engineering, and these were in general accordance with the following:-

° AS.1726 - 1993 Geotechnical Site Investigations
. AS.1289 Methods of Testing Soils for Engineering Purposes

The laboratory testing was carried out by Soil & Water Laboratories, who have NATA
Registration for the acid sulfate soil testing procedures. in addition, this report makes
reference to, and our recommendations are generally in accordance with the following

acid sulfate soils regulatory and guidance documentation:

° Queensland Acid Sulfate Soils Investigation Team (QASSIT) “Guidelines for

Sampling and Analysis of Lowland Acid Sulfate Soils (ASS) in Queensland”
October 1980.

° Queenstand Acid Sulfate Soil Technical Manuat - Soil Management Guidelines
