4.0      RESULTS OF INVESTIGATION
4.1      Site Description
The site is formally described as Lot 6 on RP216711, covering an area of 3517 m2, with a curving frontage to
Ross Crescent along the western boundary. At the time of the investigation, an existing residence was
located in the north-eastern corner of the site. The remainder of the site was a combination of sloping
grassed areas and a swimming pool to the north. Denser coastal vegetation including relatively large mature
trees and smaller shrubs was present to the south of the block.
The site was accessed via a concrete driveway sloping from Ross Crescent to a rendered blockwork garage
terraced into the slope. The existing residence (to be demolished) was a two-storey rendered blockwork
structure, terraced into the slope with a large timber deck extending out towards the east. The provided
survey plan indicates that sewer and stormwater mains run under the pavement along Ross Crescent.

In the northern half of the site a small relatively level grassed area was observed directly to the east of the
existing residence near the partially in-ground swimming pool. Some cut and fill earthworks may have been
undertaken to achieve this, however the remnant of a natural, retreating paleo dune crest may also have
been exploited. The southern half of the site sloped moderately down from Ross Crescent at what appeared
to be the natural slope. At approximately the eastern boundary and beyond the main dune fell towards the
beach at about 17°, with a small foredune observed at the toe.

The residence and other structures around the garden areas appeared to be in relatively good condition,
based on a visual exterior assessment, with no signs of structural distress which could be attributed to global
instability.
