MCU14/0106 & OPW15/0001 Compiled Information Request Response

                                                                                  MCU14/0106



Issue - Cycle and Pedestrian Facilities

Further information is required to demonstrate the adequacy of the cycle and pedestrian
facilities on-site, taking account of the overall planning for the Noosa Business Centre. For
example, Figure 3.2 does not show any footpath provisions on what has been called
Central Road. It is considered that this roadway should look like and function like a public
road, and at this location, such a road would be expected to have footpaths.

Information Required
49     Amended plans demonstrating adequate cycle and pedestrian facilities.
HYDROLOGY
Issue – Water Quality
The layout and quantum of bio-basins need to be confirmed via a refined MUSIC model that
reflects the site layout, rather than the broad simplified approach taken in the SWP.

Information Required
50     Revised MUSIC modelling to demonstrate the proposed stormwater quality
       objectives can be achieved for the proposed development layout. In particular, the
       following needs to be addressed:
       (c)     Catchment Set-up - The MUSIC model has used 1 catchment only whereas
               the developed scenario will have several catchments draining to a least 4
               different areas.
       (d)     Rainfall Set-up - The MUSIC model does not appear to have used the
               Cooroy Composite Station
       (e)     40059 for the model (i.e. 1973 -1983) as stated in the report and as per the
               guidelines. The model should be revised to incorporate this station.
       (f)     Bioretention Basins: As the basins will be used for flood attenuation, the
               basins should be checked to ensure velocities are kept below the Water By
               Design’s “WSUD Technical Design Guidelines for SEQ” Velocities should be
               in the range of 0.5m/s for minor floods (2-10yr ARI) & 2.0m/s for Major
               Floods (50-100yr ARI) + plus risk assessment of erosion potential.

Issue – Water Quality
The submitted MUSIC model does not appear to consider the impacts of waters from
catchments F1, G1 and H on the overall stormwater quality.

Information Required
51     Demonstrate how waters from these catchments will be considered in the MUSIC
       model and consistent with the proposed design.

Issue – Treatment Devices
The total size of water quality treatment devices shown on plans is not clear. The design
must allow sufficient space within the development footprint for the active filter media area
in bioretention basins. The active filter media area does not incorporate batters, inlet scour
protection and overflow devices.

Information Required
52     Provide legible scaled plans that demonstrate adequate footprint is provided to
       facilitate the required active filter media area within bioretention basins along with
       sufficient footprint for other aspects of the water quality improvement devices, such
       as batters, inlet scour protection, etc.
