MCU14/0106 & OPW15/0001 Compiled Information Request Response

                                                                                   MCU14/0106



       for the proposed development layout. In particular, the following needs to be
       addressed:
       (a)    Catchment Set-up - The WBNM model has assumed an initial loss of 7.5mm,
              typically 15mm is more appropriate for existing conditions.
       (b)    Detention Basins:
              (i)     Peak flood levels in the car park exceeds the QUDM limit of 300mm
                      for a major flood, it’s noted in minor flood peak levels exceed this limit
                      and is typically over 500mm;
              (ii)    Peak levels in the Bioretention exceeds the QUDM limit of 1.2m for a
                      20yr ARI flood, this level should be reduced;
BUSHFIRE
Issue - Bushfire
The Bushfire Assessment report applies a medium bushfire hazard level, which is
considered to underestimate the likely bushfire risk. A vegetation hazard score of 10 ought
to be used, given the state of the vegetation, the fuel loads available, and the sites existing
and continuing proximity to larger areas of highly flammable and hazardous vegetation to
the east and south.

The Assessment’s statement that the development will reduce the overall bushfire hazard
within the locality may be relevant to the existing development but is not relevant to the new
development.

The suggestion that the completion of Hofmann Drive will assist with reducing the level of
bushfire risk is not supported in the report. The report fails to acknowledge a significant
portion of Hofmann Drive abuts areas of hazardous vegetation that may restrict the safe
traffic movement of traffic due to smoke or flame hazards in the event of bushfire.

The report does not indicate that a fire management plan is required.

Information Required
56     An amended Bushfire Assessment addressing the following:
       (a)    An assessment of the Potential Bushfire Intensity likely to affect the
              proposed development using the methodology contained in the State
              Planning Policy, released in December 2013. The assessment of the
              Potential Bushfire Intensity should take into account the site connectivity to
              larger areas of hazardous vegetation such as Noosa National Park,
              vegetation along Eenie Creek, Vegetation within the Noosa Airport and open
              space dedicated to Council as part of the Noosa Business Centre.
       (b)    Depending on the levels of Potential Bushfire Intensity determined for the
              site and the surrounding area, a set of bushfire hazard mitigation and
              management actions be proposed which address the determined potential
              bushfire intensity levels. This may include a fire management plan or a
              bushfire mitigation plan.
       (c)    Provide further information with regard to the safe movement of vehicles
              along existing and proposed roadways given their location to areas of
              retained hazardous vegetation and where smoke and flame hazards might
              impact of drivers.
       (d)    The bushfire mitigation plan may update or replace the bushfire
              management plan (The Consultancy Bureau, 2004) which should include all
              areas within the Noosa Business Centre site that may not be affected by the
              proposed development in terms of vegetation clearing.
