RE:          ACID SULFATE SOILS
             ESSENCE OF PEREGIAN
             215   -   219 DAVID LOW WAY, PEREGIAN BEACH


1.0 INTRODUCTION


Butler Partners has carried out an Acid Sulfate Soil (ASS)assessment at the site and the results of the
assessment are detailed in the following report:


         Acid Sulfate Soil Assessment
         Residential Development
         215   -
                   219 David Low Way, Peregian Beach

         Project No: 07160           Dated: 18 June 2007


The ASS assessment comprised the drilling and sampling of six bores with samples taken for laboratory
testing. The subsurface conditions encountered in the bores generally comprised a surface layer of either fill
material, that varied up to a maximum depth of 0.8m, or silty sand to a maximum depth of O.4m. In two
bores drilled in the lower lying, western part of the site, the fill was underlain by natural, dark grey-brown silty

clays that were underlain in turn by silty sands that were indurated below 2m depth. In the eastern part of
the site, where the majority of the development is understood to be proposed, the surface fill or silty sand
layer was underlain by sands.

The results of the laboratory testing indicated that, in general, the fill material and natural sands and silty
sands were not ASS.          The natural silty clays indicated levels of actual acidity below laboratory reporting
limits, with one exception from a bore at the western edge of the proposed development area. The silty
clays were therefore considered to include an apparently limited amount of ASS, potentially at isolated
locations.
