The following actions will help progress the achievement of these outcomes:


MANAGEMENT            ACTIONS FOR NEXT 5 YEARS
RESPONSE
AREA

                      Review and update the Noosa Plan 2020 to ensure the erosion risks to
Land Use
                      development is appropriately planned for and considered in the design and
Planning
                      siting of new development.
                      Investigate opportunities for optimising use of existing sand recycling system
                      for enhancing beach resilience prior to erosive events
Public
recreational,         Assess possible alternative locations outside the high-risk area for re-
built, and            positioning the sand recycling system pumping station
Infrastructure
                      Investigate design requirements for the existing buried seawall to ensure it
assets
                      meets current and future coastal risk conditions, and prescribe any
                      requirements for an upgrade or replacement of this structure if required
                      Redesign beach accesses to deter foot traffic across nearby dunes along the
                      Noosa Spit
Beaches and           Investigate options for managing foot traffic within frontal dune areas of Noosa
Dunes                 Spit, including fencing design
                      Install signage for increasing beach user understanding of importance of
                      healthy dune systems along the Noosa Spit
                      Liaise with beachfront asset owners to ensure their natural disaster
Other
                      management plans are mitigating erosion event risks where possible

Other shire wide actions are also identified at the beginning of this Section.



Risks – Inundation

Inundation due to storm tide and increases in tidal extents present risks to public assets throughout
the planning horizon of this plan. In the present day, areas and assets at risk due to storm tide
include low-lying parks, road networks and buried infrastructure (e.g. stormwater networks), and
natural areas within Noosa Spit.

Permanent tidal inundation exposes many of the same assets that are subject to the effects of
storm tide inundation, however these events are lesser in area and depth, albeit on a much more
regular basis. It is this regularity that results in permanent tidal inundation representing a significant
risk to some assets within Noosa Heads. These assets include natural and recreational foreshore
assets along the river-side of Noosa Spit, Lions Park, as well as road and other network
infrastructure along Noosa Parade and Noosa Drive.

A small number of private commercial and tourism assets at the Hastings Street end of Noosa
Drive are expected to be exposed by 2100. Other private assets along Noosa Parade and Noosa
Drive are not considered at high risk from inundation due to elevated land and building floor
heights as a result of planning controls in place through successive planning schemes.
