                     a. Stormwater Quality Management

     State Planning Policy
The State Planning Policy December 2013 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.


                    HEALTHY WATERWAYS POLICY CHECKLIST                                   YES / NO
     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:
                                                                                           YES
     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 2013 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 December 2013 -
Healthy Waters policies.

A copy of the completed State Planning Policy December 2013 —Healthy Waters 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 South East Queensland Healthy Waterways Partnership’s Water by Design
