                       Approximate site location




Image 4: Extract from QGD mapping.
Core augered one borehole (BH1) using hand auger techniques which was terminated at a depth of 1.6 m
below existing ground level (bgl). The borehole encountered 0.6 m of loose to medium dense silty sand fill
(garden bed soil), underlain by firm to stiff sandy clay to 1.2 m bgl, then medium dense to dense clayey sand
(inferred extremely weathered sandstone) to the borehole termination depth. Groundwater was not
encountered within the borehole.
One dynamic cone penetrometer (DCP) test was also performed adjacent to the borehole to assess the
consistency/density of the subsurface soils. The DCP testing indicates that the below the borehole
termination depth of 1.6 m bgl, the material is inferred to be dense grading to very dense.

EXISTING INFORMATION

Topography

The subject lot is sited on the eastern slopes of a north-south trending ridgeline as shown in Image 5
(below). The topography of the lot slopes towards the east to southeast with overall slope angles measured
up to approximately 10°. The existing residence appears to have been constructed to compliment the site
contours.

Slope angles were measured on site using a hand-held clinometer.
