Information Request MCU23 0102

Issue – Stormwater Quantity & Quality
A site-based Stormwater Management Plan (SMP), prepared and certified by a suitably
qualified Registered Professional Engineer Queensland (RPEQ), is required to demonstrate
that stormwater can be managed on/from the subject land in accordance with the State
Planning Policy and Noosa Plan 2020.
Refer to Planning Scheme Policy 6 – Engineering Design Standards for further guidance on
Stormwater Management.
Information Required
Provide a SMP addressing the following:
11.   How stormwater quantity has been addressed to ensure stormwater flows discharging
      from the development are consistent with pre-development characteristics.
12.   How the development maintains the conveyance of stormwater from external
      catchments through the site in accordance with Performance Outcome 11 of the Water
      Quality and Drainage Code.
13.   How the development has incorporated the allowance for increased flood risk and tidal
      inundation through pipework as a result of climate change and sea level rise in
      accordance with Performance Outcome 2 of the Water Quality and Drainage Code.
14.   How stormwater quality will be addressed in accordance with the State Planning Policy
      and Noosa Plan 2020.
15.   Provide a stormwater layout plan and supporting information to clarify the lawful point of
      discharge (LPOD) as well as the location of any proposed quality treatment devices.


Issue – Extent of Earthworks
The total volume of earthworks undertaken has not been included on the submitted plans.
Council requires the total cut and fill volumes to determine if an Operational Works Permit is
required, acknowledging that the application material states:
      ‘It is noted that this application seeks retrospective approval for the earthworks and
      construction of the hardstand storage area, which was carried out without Council
      approval (refer to Figure 4 below). The occurrence of the works without approval was
      raised by Council via an Advisory Letter dated 20 March 2023. It is intended to rectify
      the matter with a Development Application for Operational Works upon receipt of a
      Material Change of Use approval from Council.’
Information Required
16.   Amend the plans to detail the extent and location of cut and fill that has been undertaken
      across the site.


Issue – Existing Retaining Wall
The Planning Report submitted by Adams + Sparkes (Reference: 220703, Dated: August
2023) references stability concerns with the existing retaining wall along the eastern boundary,
with the engineering consultant (Tod’s Consulting) recommending exclusion zones to prohibit
all loads from within these areas. Aerial imagery in Figure 1 below shows these areas are
currently being used to store large vehicles, directly conflicting with engineering
recommendations.




                                                                                        Page 4 of 6
