    SPP Trigger                                                    Response
    MCU with Land Area >2500m²                                          No
     -   That results in >25% Imp Area                                  N/A
     -   That results in ≥6 Lots                                        N/A
    REC with Land Area >2500m² and >6 Lots                              No
    OPW with Disturbed Area >2500m²                                     No


The above Table 6.4a demonstrates that compliance with SPP water quality objectives is
not required for the proposed development.


It is proposed to install a rainwater harvesting tank to collect roofwater and driveway
runoff. Groundwater seepage collected within a sump-pump collection system will also
discharge to the proposed rainwater tank. Harvested rainwater is to be used onsite with
connection to be made for non-potable uses and/or outdoor irrigation. A total of 6,000L
of rainwater harvesting is proposed.


Where not precluded by site conditions, it is proposed to direct hardstand areas to
landscaped areas for water quality buffering and gross pollutant removal prior to
discharge at Noosa Parade road reserve.
