                                                Engineering Report & Stormwater Management Plan
                                        Date:          16/06/2014     Document No.:     14012-ENG-01.Docx

                                         By:              AvT          Revision No.:              B


                     a. Existing Topography
The site is currently covered in grass with minimal vegetation except for a dense line of trees
running along the majority of the boundary to the site. A large area (approximately
10,700m2) to the East of the site is considered unusable land and will be left as is and used as
detention if required. There are also significant areas around the boundaries of the site to be
landscaped as buffer zones to the surrounding residential areas.

The levels on the site range from approximately RL121.3 in the South West corner down to
RL104.2 at the Eastern side of the site. A detailed survey has been conducted on this site by
Saunders Havill Group Pty Ltd, dated 17 March 2014. Refer to Appendix A for current survey
plan. The site is currently surrounded by undeveloped land to the South East and residential
land to the North West. The Bruce Highway lies to the South East of the site, and an existing
golf course to the North East of the site.

The existing lot is currently vacant and has not been developed in the past.

                     b. Proposed Land Use
The proposed development involves a new multi-use development and associated car parking
and internal roadworks. A proposed service station with a fast food drive thru outlet and a
supermarket are to be located to the North of the site, with a carwash facility to the South of
this. To the South of the site a proposed caravan tourist park is to be located, with a proposed
storage facility to the West of this.

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 high as the proposed development
involves a large 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 platforms and
roadworks. 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.
