C6361-22-ENG - Feb 2023 - V1

The intended land use (rural residential plus balance rural allotment) is considered low
impact with respect to pollutant load generation when compared to typical urban
developments. The target pollutants for water quality management in new developments
are typically organics (phosphorous and nitrogen), suspended solids (sediment) and gross
pollutants (litter). A large percentage of these pollutants are released to downstream
waterways as a result of land disturbance associated with earthworks and building
operations. The proposed development works will include erosion and sediment control
measures during the construction phase and minimal pollutant load generation during
the operational phase.


Proposed new pavement areas will be directed to a vegetated swale drain (>100m) long
which will provide primary and tertiary water quality treatment prior to discharge at the
existing waterway. The high overall percentages of pervious surfaces within the site will
disconnect impervious areas and promote infiltration of stormwater runoff.


7.0    SEWERAGE


The revised development application proposes rural residential and rural allotments.
Onsite treatment of wastewater will be provided for each new allotment. Details of
proposed treatment systems to be provided as part of future Building Applications to
Noosa Shire Council.




8.0    WATER SUPPLY


A layout of the proposed water reticulation is included on Drawing Number C6361/22/P06
in Appendix B.
