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

Regular inspections are critical to the management of Stormwater Infrastructure and the inspections
undertaken by Council, and by third party providers will meet the standards and statutory
requirements to ensure all assets meet the intended design performance. The scheduled
maintenance activities will be within the defined timeframes to ensure that all potential or identified
defects are rectified.

Levels of service must be readily measurable and preferably from available data sources. Each level
of service should be stated in terms of appropriateness and understood by the community for whom
the service is provided. The levels of service in this AMP are intended to:

   Measure of the effectiveness of this AMP;
   Inform the Noosa community of the proposed type and level of service to be offered by Council;
   Assist with identification of the expenditure and benefits of the Noosa Council services being
    offered;
   Inform the Noosa community to assess the affordability and suitability of the Noosa Council
    services being offered;
   Provide focus for the development of future Stormwater Infrastructure asset management
    strategies;
   Provide guidance for current and future services to be offered; and
   Define the specific levels of service provided by Noosa Council.

The levels of service outlined in this Stormwater Infrastructure AMP are also aligned to:
 Statutory, legislative and relevant code requirements.
 Information obtained from asset condition assessments and maintenance analysis; and
 Noosa Council’s Corporate Plan.
The levels of service have been catalogued and are located at Annex A.


       Measured Levels of Service
To demonstrate the levels of service of the Stormwater Infrastructure assets, Noosa Council
undertook an exercise to define the service outputs of the stormwater Infrastructure assets. These
service outputs are tabled at Annex A. The service output documents are to be utilised to inform
responsible staff of their obligations in maintaining the current levels of service. When targets are
not achieved, they should be escalated and reported through the Asset Management Governance
Framework.


3.                Future Demand
       Demand Drivers
There is currently an inconsistent approach of demand management applied to the management of
the Stormwater Infrastructure. Flooding of dwellings is the key driver for Council to act on potential
upgrades. Climate Change adaptation and the retrofitting of assets to prevent flooding in the climate
change adaptation high risk areas is currently being considered.

The stormwater systems are designed to carry water runoff and thus have the potential to transport
pollutants into Noosa’s water catchments. Therefore, future consideration to install environmentally
protected devices and structures for the filtration and capture of pollutants to improve the overall
environmental objectives of Noosa Council will be a key demand driver into the future.

Flooding and community safety are key demand drivers on the current and future levels of
serviceability for Stormwater Infrastructure. Improved monitoring of these activities should act as an
indicator to reviewing demand management for specific assets within the Stormwater Infrastructure.
