                     a. Stormwater Quality Management

     State Planning Policy
The State Planning Policy July 2014 applies for stormwater quality management and
management of new or expanded non-tidal artificial waterways applies to development that is
outlined below in Table 5.1.

          SPP2014 PART E: INTERIM DEVELOPMENT ASSESSMENT
                                                                                         YES / NO
           REQUIREMENTS. STATE INTEREST – WATER QUALITY
     Material change of use for urban purposes that involves a land area
     greater than 2500m2 that:
        will result in an impervious area greater than 25% of the net
        developable area                                                                   YES
          Will result in 6 or more dwellings                                               NO
     Reconfiguring a lot for urban purposes that involves a land area
     greater than 2500m2 and will result in six or more lots:
                                                                                           NO
     Operational works for urban purposes that involve disturbing more
     than 2500m2 of land
                                                                                           YES
      Table 5.1:      Water Quality Objectives

As the proposed development triggers one or more applicable items in the above Table 5.1,
the State Planning Policy December 2014 is applicable and compliance will be expected by the
local government authority.

To achieve the above State Planning Policy outcomes the development is to:
     avoid or minimise development impacts arising from altered stormwater quality and
        flow by providing for development and construction activities in accordance with
        acceptable design objectives
     avoid or minimise development impacts of waste water (other than contaminated
        stormwater) on water quality objectives
     avoid or minimise development impacts arising from the creation or expansion of
        non-tidal artificial waterways such as urban lakes

The proposed development will comply with the State Planning Policy July 2014 – Water
Quality policies.

A copy of the completed State Planning Policy July 2014 —Water Quality development
assessment code is attached in Appendix E.


                     b. Water Quality Objectives

Water quality parameters and the proposed limits applicable to this site have been selected in
accordance with SPP2014 Appendix 3, Table B and MUSIC Modelling Guidelines for South East
Queensland Version (2010).
