Fig 9: Queensland WetlandInfo mapping

The 2004 Waterways and Riparian Buffer Analyses informed the mapping of waterways and riparian
buffers of the superseded Noosa Plan 2006. In this plan, the site has no waterways shown, as sites with
less than 5% slope and more than 30m from a DNR mapped waterway were clipped out of the Noosa
Plan 2006 waterways dataset (Fig 10). The document states “The algorithms used to generate the flow
of water and thus the waterways become less accurate as the slope of land decreases from the
moderately dissected uplands to the gently dissected and flat lowlands. For the purposes of establishing
riparian buffers, those generated waterways not within 30 metres of a DNR waterway were removed.”

The mapping associated with the superseded 2006 Noosa Plan do not show any waterway on the site, to
the extent of the buffer area. This riparian buffer mapping does not accord with the rationale put
forward in the 2004 Waterways and Riparian Buffer Analyses, where the purposes of establishing
riparian buffers, those generated waterways not within 30 metres of a DNR waterway were removed
(Fig 11). This site should not have riparian buffers applied accordingly.
