 3.0     NATURE OF IMPACT
 3.1     Location of impact

The Noosa Landfill and Resource Recovery Centre is situated at 561 Eumundi Noosa Road,
Doonan (Lot 77 SP298776). The potential Impact Area lies on the eastern edge of the
proposed new landfill cells 2.3 and 2.4 and covers an area of approximately 27,800m2. This
potential Impact Area has the potential to be impacted by groundwater lowering or changes
in surface water flows. There is also clearing of approximately 6,500 m2 for the southern
stormwater discharge area. This area includes both the discharge drain and an associated
buffer area.

The eastern edge of the landfill contains patches of weedy regrowth, with some planted
areas in and around the sediment basins, ponds, dams and access tracks. Immediately
adjacent to the landfill, the Land Zone 5 supports an Endangered Scribbly gum woodland
vegetation community (RE 12.5.3) which occurs to the north east and south east, as well as
a Least concern Eucalypt woodland vegetation community (RE 12.5.4). Land Zone 3
supports Closed heathland (RE 12.3.13) and Melaleuca wetland vegetation communities
(RE 12.3.5). The Eucalypt-dominated vegetation communities transition to closed heath
and/or wetland at several locations where the shallow water table intersects the ground
surface in low-lying areas and along drainage lines.

The mapped vegetation provides habitat for the following species of conservation
significance: Koala (Phascolarctos cinereus), Wallum Rocketfrog (Litoria freycineti) and
Wallum Froglet (Crinia tinnula), which are all listed as Vulnerable under the Nature
Conservation Act 1992 (NCA), as well as Swamp Crayfish (Tenuibranchiurus glypticus)
which is listed as Endangered.

The southern and eastern extremities of the allotment are intersected by road reserves and
are allocated as Weyba Nature Refuge to the south and east of the road. These are managed
for conservation purposes by Noosa Council’s Natural Areas team. The Noosa National Park
adjoins the south-western property boundary, located to the south of those features. The
area to the north (the balance of the allotment) is zoned for Community Purposes under the
Noosa Plan.
Topography along the survey area is generally flat with minor depressions and elevation
ranging from 10 to 15 metres above sea level. Existing surface water flows north and north-
east from the landfill.

 3.2     Duration of impact

Noosa Council has not yet finalised the specific timing, duration and design of the proposed
works, however it is anticipated that works will begin in 2022. The SMP will be enacted
upon the commencement of works and will remain active for a period of twelve (12) months
following the completion of works.

Construction of Cell 2.4 is estimated to take less than six months to construct. It is expected
that construction of Cell 2.3 will take around nine months depending on the volume of
earthworks undertaken as a result of day cover excavations. However, it is foreseeable,
since Cell 2.3 is a large cell, it may be constructed in (up to) three phases. Around four to
six months is allowed for each construction phase.
