8.0      CONCLUSION
The proposed development has been analysed to provide the design requirements to meet the local
authority guidelines for stormwater quality & quantity outcomes described in this report.



The lawful point of discharge for the subject site is Council existing stormwater infrastructure in the
Blakesley Street road reserve.



Sediment generated during the construction phase is to be dealt with in accordance with a Silt and
Sediment Control plan and is to be retained on-site throughout construction.



The proposed development does not triggers the State Planning Policy 2017 for stormwater quality
treatment objectives, however The Noosa Plan 2020 PO6 requires stormwater quality treatment
measures. Stormwater runoff from the proposed development will be drained through a water resue
tank and bio-retention bed located on-site. Stormwater pits are to be fitted with gross pollutant traps
in areas prone to gross pollutants.

As requested by Noosa Council, on-site detention has been provided to maintain existing peak flow
rates. On-site detention is proposed to be contained within underground tanks and designed to contain
all flows up to a Q100 storm event.



The subject site is within a defined flood area. The minimum floor level is set a minimum of 300 mm
above the defined flood level.
