1.0     INTRODUCTION
This report presents the results of a geotechnical investigation and slope stability assessment for a proposed
residence at 317 Lawnville Road, Black Mountain.
The work was undertaken in accordance with proposal Q003778-001-L-Rev0.

2.0     PROPOSED DEVELOPMENT
We understand the proposed development comprises construction of a two-level residence including a pool,
garage and driveway. Drawings provided by K Architecture (SK.01 To SK.09, 18 November 2022) indicate a
proposed cut of about 2.5 m vertical height into the slope at the south-western corner of the residence
footprint, supported by a tiered retaining wall. Downslope filling works are also proposed (possibly up to
about 2.5 m height) supported by a block retaining wall.
