Amended Ecological Assessment Report

                                                                               Ecological Assessment Letter




The system does not require vegetation removal for installation, nor does it impact the ground as the
irrigation pipes and sprinklers are placed on top of the ground (no excavation). The most that may be
required would be some minor understorey vegetation pruning. The rainforest understorey vegetation
in this location would be well suited to the additional moisture that would be released in this area.

The proposed effluent disposal system is unlikely to have any negative impacts upon the Noosa River /
riparian zone, in terms of water quality or ecology. This is due to the large setback to the river and
riparian buffer area, and the fact that the system is located in a heavily vegetated, elevated area. The
amount of filtration that will occur as water percolates through the soil will be highly likely to eliminate
any excessive nutrients (nitrogen, phosphorus) and pollutants (metals, suspended solids etc) from the
waste-water before it gets to the riparian zone. Nutrient uptake from plant roots will also assist in this
process.

In terms of the swimming pool, the pool backwash from filter cleaning and pool overflow will be directed
into a rubble pit that will then run into stormwater drainage pipes, across the grass swale and into the
existing dam on site. This multi-stage treatment train will be a suitable treatment method for filtering and
cleaning the pool water.


5.2.2 State legislation

State Code 25: Development in South East Queensland koala habitat areas,

The site is not mapped in the Koala Priority Area (KPA) but it does contain mapped Koala Habitat Area
(KHA) (Koala Conservation Plan Map; administered by DES). However, the proposed house location is
not within the KHA and therefore the application does not have to be referred to SARA and comply with
State Code 25: Development in South East Queensland koala habitat areas. The waste water irrigation
area does not interfere with native vegetation and therefore this also does not trigger referral.

Vegetation Management Act 1999

The site is mapped as supporting regulated vegetation (Category B remnant) under the RVM map,
however vegetation clearing associated with the development is exempt clearing under the Planning
Regulation 2017 (lot size is less than 5 ha).

Coastal Protection and Management Act 1995

The site is mapped within the Coastal Management District and is within a Coastal area subject to
erosion and storm tide inundation. However, the proposed development footprint area is outside of the
Coastal area subject to erosion and storm tide inundation. The site inspection confirmed that the
development footprint area is outside of the coastal area subject to erosion and storm tide inundation.
The development area is still within the Coastal Management District. However, the ‘State Code for
Accepted Development For Tidal works, or work completely or partly in a coastal management district’
(August 2017) is not applicable to this application, because the application does not involve works that
are required to be assessed under that code. Therefore, no further assessment is required under this
Act.
