Att 3 - Landslide Risk Assessment

Warning: Our classification has not allowed for any future tree(s), which may be planted as part of
the future landscaping. The owner, future owners and any stakeholder/consultant who is involved in
the landscaping, has a duty of care to ensure that any future planting does not adversely affect the
proposed dwelling and both Appendix H and CH AS2870-2011 and the referenced CSIRO
documents give guidance on “Acceptable Long Term Site Management”. Therefore, it would be
prudent for any such proposal to be presented to the design engineer as soon as it is available, to
ensure that the design engineer is satisfied that the landscaping proposed will not adversely affect
the footing system.
Note: Cutting and filling the site by depths equal to or greater than 400mm will result in a ‘P’
classification, which may increase the design ‘ys’. Therefore, when the proposed cut and fill
earthworks is known, we shall be forwarded the earthworks plan to determine the potential impact on
the above recorded calculations.
Unless specifically mentioned elsewhere within this report, we make no representation about the
trafficability of the site during construction, however the thicker the topsoil/estate dressing, the greater
the problem with moving construction equipment during or after rain periods.
