                     a. Existing Topography
The site is currently developed, accommodating several sheds, a low-set timber house and
concrete paving, covering a total of approximately 91% of the site. The balance of the site
(277m2) is landscaped with mixture of turf, paving and several medium sized trees.

The site grades evenly from a level of approximately RL115.0 in the south east corner on
Garnet Street down to approximately RL111.5 in the north west corner in Wimmer’s Lane to
the rear. A detailed survey has been conducted on this site by Saunders Havill Group Pty Ltd,
dated 20 March 2015. Refer to Appendix A for current survey plan. The site is bounded by
commercial buildings with a hotel complex opposite in Garnet Street. A residential dwelling
exists to rear of the western neighbouring property entering on to Wimmer’s Lane at the rear.



                     b. Proposed Land Use
The proposed development involves a new supermarket development and associated car
parking (including basement).

Refer attached Appendix B for proposed layout plans and details.


 2. Erosion and Sediment Control

Using the Noosa Sediment and Erosion Control Assessment form in Appendix C, it is
considered that the erosion risk proposed by the site is low as the proposed development
involves an area of land which will only be exposed for a minimal amount of time during the
earthworks required for service trenching and constructing the building basement, platform
and car-parking. The trenches will only be exposed while the services are being installed and
then will be covered by the proposed building works. To further mitigate the impact of the
development construction an Erosion and Sediment Control Plan has been prepared and is
included in Appendix B. Appendix D shows the International Erosion Control Association
Australasia standard drawings and control notes applicable to this development.

The construction contractor is responsible for ensuring that soil and debris does not leave the
site as well as the confines of the construction zone and is not deposited on external roads or
existing in-use areas due to the proposed earthworks and construction activity.

     Acid Sulphate Soils
The local council is listed in Table 4: Acid sulphate soils-affected local government areas in
State Planning Policy July 2014 and therefore this development application requires
compliance with the State Planning Policy July 2014 acid sulphate soils development
objectives.
