Issue – Cooroy Sewage Treatment Plant
The site is within proximity of Cooroy Sewage Treatment Plant.
Information Required
2. Provide an Environmental Report addressing the potential for odour impacts on the
   proposed development.


Issue – Noise Impacts
The site adjoins the Jarrah Street industrial area and industrial zoned land located at the end
of Jarrah Street. The existing industrial uses may impact on the amenity of the development
and the proposed residential use may restrict the future development of the industrial zoned
land.
Information Required
3. Provide a noise report addressing the potential impacts of the existing industrial land on
   the proposed residential development. The report is also to address the potential for
   reverse amenity impacts/ restrictions of the proposal on the existing and future industrial
   uses in the area.


Issue: Flooding
The access to the site via Carpenters Road is heavily constrained by flooding. Significant
improvements to Carpenters Road will be required in order to achieve access which has the
required flood immunity and such upgrades have the potential to worsen flooding on upstream
properties, which must be quantified.
Information required:
4.   Provide a Flood Impact Assessment, prepared in accordance with ARR2019 and QUDM,
     which demonstrates the following:
     a)   That Carpenters Road can be upgraded to a standard which achieves immunity for
          the 10%AEP flood event and trafficability in the 1%AEP at year 2100;
     b)   That such upgrades of Carpenters Road will not cause afflux to upstream properties
          for a range of flood probabilities up to and including the 1%AEP (2100);
     c)   That assessments undertaken for points (1) and (2) appropriately allow for design
          blockage rates of cross-drainage structures;
     d)   That in the case of either a severe storm exceeding the DFE or a severe blockage of
          cross drainage structures, the performance criteria for such scenarios specified in
          QUDM are met.


Issue: Stormwater Quality
Information required:
5.   Provide a Stormwater Quality Management Plan which demonstrates how the pollutant
     load reduction targets will be achieved for the site and for the upgraded section of
     Carpenters Road, as required by the Water Quality and Drainage Code. Include
     preliminary sections for treatment devices showing that such devices will be able to
     function effectively in the proposed locations by achieving a free-drainage outlet from any
     sub-soil drains.
