                                                                                 MCU14/0056



Guidelines for Water Quality Management in Drinking Water Catchments of 2012 is relevant
to the development.

Information Required
14     Demonstrate how the development will achieve the State Interest, as described in
       the State Planning Policy Guideline – State Interest – Water Quality August 2014.

15     Demonstrate the development is consistent with the SEQ Water Development
       Guidelines: Development Guidelines for Water Quality Management in Drinking
       Water Catchments 2012.

Issue - Flooding
The development site (particularly the area of the proposed tourist park) may be subject to
flooding and stormwater ponding during major storm events. The proposed development
may adversely impact on the existing flooding and drainage conditions on other properties
and/or public roads.

Information Required
16     Provide detailed assessment of the upstream drainage catchment/s taking into
       consideration any overflows from adjacent catchments and stormwater runoff from
       roads (eg from Bruce Highway) onto the site. The assessment and report must be
       prepared by RPEQ specialised in this field and include in particular:

       (a)    Plan/s and data showing the extent of flooding (floodline) for 1% AEP storm
              event on the development site and the relevant downstream properties and
              roads (eg the Golf Course and Myall Street) for pre-development conditions.
       (b)    The general internal drainage layout and any proposed or anticipated
              required stormwater drainage works and mitigation works external or internal
              to the site.
       (c)    Plan/s and data showing the extent of flooding for post development
              conditions on the fully developed site and the relevant downstream
              properties and roads for 1%, 5% and 10% AEP storm events.
       (d)    Identification of potential adverse impact on other properties and
              recommended mitigation measures.

Issue - Earthworks
The survey plan indicates the difference in ground levels across the proposed development
area of approximately 10 metres. Significant earthworks and retention works throughout
the development site are likely to be required.

Information Required
17     Provide plan/s to illustrate the estimated amount and levels of the earthworks
       required on the site and include cross sections to demonstrate the changes in
       finished levels, and associated structures, within the development site.

Issue – Heavy Vehicles
Insufficient details have been provided regarding the types (particularly refuelling trucks),
access paths and manoeuvring of trucks for deliveries and services on the site.
