1.0 INTRODUCTION

In accordance with the relevant codes, standards and Noosa Councils guidelines
Unearthed Geotechnical P/L was commissioned to undertake a Site and Soil
Evaluation at Lot 12 SP139169 (*71) Coveys Road, Tinbeerwah.

The results form the basis of our recommendations for the on-site treatment and
disposal of wastewater from the proposed four bedroom house and shed on this
10.768 hectare allotment.

A representative of Unearthed Geotechnical P/L was met and shown to the proposed

site by the owner, S Fleming. Our site investigation fieldwork was performed on
3/03/2023 after some recent rain activity in the course of the preceding weeks.
