As required by the National Water Quality Management Strategy “Guidelines
for Sewerage Systems — Use. of Reclaithed Water and as detailed in the EMP a
program will be developed and implemented to monitor effluent, surface:and

. groundwater water quality to ensure the environmental values of the land and

surrounding land are protected. k

Drainage and Flooding

Drainage was considered by Cardno MBK as part of its assessment. of
infrastructure provision (see Annex E: Noosa North Shore Eco-Tourism Portal
Infrastructure Assessment).

The. assessment found that the proposed’ development does not alter existing
drainage paths, which generally exit the development site on the northern and
eastern sides. The nearest open water body is Lake Cooroibah, which is
located some several kilometres downstream with extensive wetlands located
between it and the proposed development.

Potential impacts of development were assessed using AQUALM (XP
Software) with established ‘parameters to determine potential pollutant
loadings. The AQUALM analysis indicated that the. expected pollutant
exporis from the proposed develapment can be reduced to-sustainable loads
by the implementation of appropriate stormwater quality treatment measures.
These measures comprise the use of filter strips/swales in the East Visitor

. Precinct and the use of bio-retention systems followed by treatment within the

proposed lake at the West Visitor Precinct.

The AQUALM analysis also indicated that there is sufficient runoff in the
West Visitor Precinct to maintain a functional body of water within the lake,
provided infiltration losses are minimal.

Given the size of the catchment and the topography of the site, there are
predicted to be no flooding issues associated with the proposed Noosa North
Shore Eco-Tourism Portal.

Waste Management

Waste Management at the proposed Noosa North Shore Eco-Tourism Portal
will be conducted through the construction and operation of two waste
transfer stations to be strategically located adjacent to the proposed sewage
package treatment plant (for the East Visitor Precinct) and the proposed
services workshop (West Visitor Precinct). Waste management practices will
be based upon techniques that reduce the volume of waste produced,
encourage reuse and recycling of waste products and minimises the volume of
waste disposed to landfill.
