SLOPE STABILITY ASSESSMENT
Address : Lot 27 Noosa Dunes
Marcus Beach
Client : K & B Monahan
Date : 8 September 2016
Report No : 26250(S)

INTRODUCTION
SCG Consulting Engineers have been commissioned to provide a Slope Stability Assessment for the above
allotment. The assessment considers only the existing state of the allotment and any possible effects that the
proposed works will have on this site.
The proposed works are detailed by Aboda Design Group in plans WD.01 thru WD.604.
SITE DESCRIPTION
A desk top study of the site confirms the following:-
- The site is located in an area identified as ‘Sand Dune Problem Area’ on the Noosa Shire Council’s
Landslip Maps.
- Reference to the Australian Geological Map 1:100000 Gympie Special confirms the site is located within
the Quaternary Sandbed.
Field work has been undertaken which included explorative testpits/boreholes by 1st Independent Soil Testing,
together with a walkover of the site by SCG Consulting Engineers.
The borehole logs contained in 1st Independent Soil Testing report No.16/359 dated 26 April 2016 confirms the
soil profile to consist of the following –
: LOOSE SILTY SANDS INCREASING IN DENSITY WITH DEPTH
Our walkover confirmed the following characteristics-
Site Slope : A visual assessment of the surface grades within the allotment using
a hand held inclometer suggests grades in the order of 18% exist
across the proposed construction site.
Vegetations : Vegetation consists of scattered trees and dense undergrowth.
Slope Shape/Location : The surface profile across the allotments slope faces are generally
LINEAR PLANAR.
Drainage : The surface drainage is good, sub-surface drainage is good. There was
no indication of ground water seepage or rising water pressure.
Stormwater flows from upslope of the allotment will be intersected and
captured by the road reserve.
Earthworks : There is no existing earthworks apparent.
Adjacent Structures : Adjacent structures on the neighbouring properties appear to be a mix of
slab on ground and suspended timber framed floors.
Evidence of previous
Soil Movements : None apparent.
LANDSLIP MECHANISMS
Landslip is generally defined as the movement of a mass of rock or soil down a slope.
It is generally considered to occur when the strength of the soil or rock mass to support itself is exceeded
causing movement to occur within the mass.
This loss of strength can occur as a result of numerous circumstances. These include, but are not limited to the
following:-
Page 4
- Siesmic Activity
- Erosions effects such as wind or fluid scour
- Soil Saturation from rainfall events or defective drainage measures
- Construction/Earthworks activities
- Groundwater variations/movements
- Previous Landslips
The nature of landslips vary with site specific conditions and failure mechanisms that cause the slips to occur.
Appendix B provides some diagrammatic examples of various landslips.
The speed of landslips can vary greatly from millimetres per year to a number of meters in a matter of minutes.
Once again this characteristic is governed by site specific conditions and the failure mechanism causing the slip
to occur.
The allotment is situated within a massive aeolian sand bed of Quaternary age. As a general observation dunal
horizons such as these are stable where;
- The natural slope is less than the angle of repose for sand (30)
- Vegetation exists to protect from wind generated scour
- The drainage pattern is such that there is no risk of fluvial scour.
These horizons can become unstable when aeolian or fluvial scour erode slopes to angles greater than 30,
particularly when coincident with vegetation removal.
LANDSLIP HAZARD ASSESSMENT
For our assessment we utilise the Guidelines For Landslip Risk Management Framework as provided by the
Australian Geomechanics Society, in their journal of March 2007. Descriptions used by this framework can be
found appended to this report.
Using the Qualitive Risk Analysis Matrix (refer appendix) we have established the following characteristics for
the allotment.
Landslip Mechanism : Translational, Rotational or Creep Flow
We consider a potential landslip mechanism will consist of either a Rotational or Translational Landslide or
Creep movement within the sloping profile. Diagramation representation of these mechanisms are
appended to this report. We are of the opinion that this movement could occur following over excavation
or scour.
Likelihood of Landslip : Likely
This is due to the evidence during our site visit which the surface grade within the allotment.
Consequences to Property : Minor
With these factors considered we classify the allotment as:-
MODERATE RISK OF LANDSLIP
Although we consider the allotment has a moderate risk of landslip, building work undertaken on the site should
follow accepted methods which assist in maintaining slope stability.
Such measures are discussed in the following section.
HAZARD MITAGATION – CONSTRUCTION RECOMMENDATIONS
We consider the primary risks for landslip occurring within this allotment is over excavation or, stormwater scour
and vegetation removal.
The construction of any cut/fill platforms within the site will lead to an increased risk of landslip.
SCG Consulting Engineers 3 SCG Ref: 26250(SL)
Page 5
Any over excavated (steep) cuts may lead to landslip. Similarly, steep fill batters may be susceptible to slip or erosion. Any exposed fill batters are susceptible to weakening from saturating rains and stormwater scour. This risk is compounded, where poor compaction is achieved when placing the fill. Any fill batter profiles should be limited to a maximum grade of 1 to 3 (vertical to horizontal). Where possible the fill platform should be benched into the natural profile after the removal of all organic material including topsoils.. Surface stormwater runoff should be diverted around fill batters. Vegetating the fill batter can improve the batters ability to resist slip and or scour. Where these recommendations are unachievable, benching, shoring or retaining measures should be implemented. Any permanent exposed cut batters should be limited to a maximum slope of 1 to 2.5 (vertical to horizontal). The face should be protected from stormwater scour with cut off drains above the cut. Catch drains should also be provided along the base of the cut. The drains must dissipate all stormwater from above and below the cut. Vegetating the cut batter can improve the batters ability to resist slip and scour. Steeper batters should be retained with engineer designed retaining walls. All excavations both temporary and permanent must be adequately battered or retained to prevent collapse. Temporary excavations for retaining walls can have exposed cut batters of 1 to 1.7 (vertical to horizontal) taken from the base of the excavation. These earthworks must incorporate shallow surface spoon drains at the base and along the high side of the cut. Drains must have an efficient outflow down-slope and clear of the construction area. Any exposed soil face should also be protected against the potential for stormwater erosion. Saturation of the exposed cut batter from prolonged rainfall will potentially de-stabilise the cut batter. Programming of the works must consider this possibility. Temporary backfilling of the slope may be required. Should these recommendations be un-achievable the builder should seek guidance from this office on temporary shoring, benching or other suitable techniques. The allotment will support a typical form of residential construction. Structural foundations should be designed by a competent person in accordance with AS 2870, accepted engineering theory and the geotechnical conditions reported by this office. All earthworks should be constructed in accordance with AS3798-1996 ‘Guidelines on earthworks for commercial and residential developments’ and sound engineering theory. The builder must ensure the stability of neighbouring structures is maintained through not undermining their foundations. This is achieved via restricting any earthworks to above a line radiating downwards at an angle of 1 in 1.2 (vertical to horizontal) from the base of the foundation/structure to be protected. The proposed method of construction is for a blockwork dwelling supported on ground slabs. The allotment is suitable for this form of construction, any excavations for lower floor areas must adhere to the recommendations contained herein. Retaining walls for landscaping purposes would need to be constructed with consideration of maintaining stability of the surrounding ground during construction. Such measures would include limiting the slope of any excavations to a slope of 1 vertical to 1.7 horizontal and protecting the works against stormwater scour. The retaining wall designs must allow for the lateral soil pressures expected including additional surcharging from sloping backfills. Although we consider the allotment stable in its current form there will always be a risk of landslip under severe stormwater conditions. Measures that will reduce this risk include the following but are not limited to. The finished ground surface should be leveled and graded to ensure no concentration of stormwater runoff leading to ground scour can occur. Any collected stormwater from areas other than the roof should be disposed of downslope from the proposed dwelling and should also ensure no ground scour can occur. All stormwater runoff from hard landscaped areas should be directed around the perimeter of the house and contained within the site via diversion bunding, scour proof drains and field inlets. SCG Consulting Engineers 4 SCG Ref: 26250(SL)
Page 6
All stormwater collected from roofed areas should be directed to storage tanks for re-use. Overflow from the
tanks should be disposed of via rubble soakage pits downslope of the dwelling.
No stormwater runoff should be allowed to flow over any exposed excavated embankment faces or filled batters.
Areas adjacent existing gullies must be protected against stormwater scour are susceptible to instability from
erosion effects and over saturation. With this considered, structures should not be located adjacent gullies.
Also, the area adjacent the flanks of the gullies should be protected from scour via vegetation and limiting
surface grades.
All existing cross allotment flows from neighbouring properties must also be considered, managed and
maintained. Clear unhindered drainage paths must be provided and maintained during and beyond construction.
All constructed retaining walls must have effective drainage measures upslope and beyond the walls to relieve
any sub-surface water pressure/build-up. These drains must be maintained and flushed out regularly. To
achieve this we recommend bringing the upstream end of the drain to surface and capping off to allow future
flush out.
We have attached guidelines for hillside construction extracted from Australian Geomechanics vol. 35 March
2000 – “Landslide Risk Management”. These references provide commentary on good design and building
practice.
We trust this meets with your requirements, however should you have any queries on the above matter please
