2019-02-12 Attachment 1 to Item 3 - Stormwater Infrastructure Asset Management Plan

As the Stormwater Infrastructure assets age, continued condition assessments are required to
monitor the assets and produce more defined renewal plans. The graph below enables Council to
identify and plan for these significant renewal activities for the next 10 years.




Figure 7: Stormwater Infrastructure Asset Renewal Costs


The above graph identifies the future investment required in renewing Stormwater Infrastructure over
a 10-year period. The development of detailed renewal programs for all stormwater assets will result
in the completion of asset condition assessments. Projects currently identified have been listed in
Annex D and is reflected in the development of Council’s future 10-year Capital Works Program.



       Capital Upgrades and New Assets
There is a need to develop more maturity in the overall assessment and management of our
Stormwater Infrastructure assets before there is a consideration for further upgrades and expansion
of the Stormwater Infrastructure assets. The modelling of increased tides, rising sea levels,
increased storm intensities and other factors relating to climate change must be considered in future
modelling when upgrading or constructing major stormwater infrastructure.

In summary, the demand drivers highlighted in section 3.1 will dictate the development of capital
upgrade and new stormwater infrastructure in the future.



       Capitalisation of Assets
All new and renewed assets will be acquired and commissioned in accordance with the Noosa
Council Capital Delivery Framework.
