5.0     SUMMARY & CONCLUSIONS
Based on the findings of our assessment we consider that there would be a Low Risk of slope instability
subject to implementation of the recommendations given in this report, in particular:
       The proposed residence is to be supported on footings founded at least 300 mm in to weathered
        rock.
       Diversion drains are established above cut and fill batters
       Ensuring that stormwater collected by drainage, including any overflow from tanks, is directed to
        discharge at least 10 m down slope of any fill and structure.
       All cut/fill is battered no steeper than 1V:2H or supported by retaining walls.
       Vegetation must be established and maintained to prevent erosion of currently bare soils.
