1 Executive Summary
1.1 Background
The Asset Management Plan is prepared to provide a record of:
The state of Council’s road infrastructure assets at the close of the past financial year;
Key achievements in the past financial year;
The 10-year funding required to achieve Council’s adopted asset performance targets; and
Planned Asset Management activities for the current financial year.
This Plan encompasses the roads asset class, including the following.
Sealed Roads – Surface and Pavement
Unsealed Roads
Kerb and Channel
Footpaths
Council roads are classified for maintenance and renewal purposes in accordance with the following hierarchy.
Road Classification
Functional Definition
Rural Roads & Urban Roads
A A road that carries predominately through traffic.
B A road that carries a mixture of through and local traffic.
C Carries mainly local and some through traffic.
D Provides access to residence and and/or minimal through traffic.
E Provides access to properties, unsealed.
F Unmade or unformed roads.
G Leased roads.
Council footpaths are classified using the hierarchy outlined below based on pedestrian volume, utilisation and likelihood of risk.
Classification Functional Definition
General Footpath Description and Performance Requirements
High Usage Town Centre, shopping precincts footpaths
Concrete footpath, 2.0 to 2.5m wide (minimum) with or without nature strip or
Asphalt footpath, 2.0 to 2.5m wide (minimum) with or without nature strip or
Brick or concrete paved footpath, 2.0 to 2.5m wide (minimum) with or without nature strip

Classification Functional Definition
General Footpath Description and Performance Requirements
Medium Usage School, Community (i.e. Nursing Homes, Hospitals, Church) areas
Concrete footpath, 1.2m to 2.0m wide (minimum) with or without nature strip or
Asphalt or Spray Seal footpath 1.2m to 2.0m wide (minimum) with or without nature strip
Low Usage Residential areas Concrete footpath, 1.2m to 1.5m wide (minimum) with or without nature strip or
Asphalt or Spray Seal footpath 1.2m to 1.5m wide (minimum) with or without nature strip
Compacted granular unsealed footpath 1.2m to 1.5m wide (minimum) with or without nature strip
These classifications are used to determine priorities for maintenance, repair and renewal.
The Asset Management Plan is to be reviewed as soon as practical after the close of the financial year it is Planning on and before the budgets are set for the financial year following the year in which the Plan is written. Ideally, the Asset Management Plan should be available to an incoming Council following an election.

1.3 Key Achievements
Council has adopted a program of ongoing desktop update of the Asset Management Plan every year with a comprehensive update every four years.
Council has committed to and successfully completed two rounds of electronic road data auditing. This includes pick up of road, kerb and footpath inventory and condition every four years. The condition is assessed by video imagery of high resolution and includes six road distress failure modes based on the Austroads methodology.
Council has applied a state of the art sophisticated predictive modelling analytical process for determining future funding requirements for renewal of the roads and road side assets. The analytics utilise condition data to project future scenarios and perform what-if analysis. This enables councils to validate and prescribe affordable service levels.
Council has revalued its road network in 2011 and 2015 in full compliance with the Australian Accounting standards.

The Councils Long Term Financial Plan has been analysed against the predicted impact of the funding levels on asset condition. Modelling has also been undertaken in recognition of an increased service standard over the next 10 years. The level of funding is required to maintain the average asset condition to a minimum of Fair (Service Level = 2) condition.
The Condition Index and Remaining Useful Lives contained in the Council’s Asset Management System have been used in the budget and condition forecasts.
The predicted Service Level (Condition) for the LTFP is shown below. The budgets have been projected for 20 years to indicate the longer term effect on the asset condition. Further details are included in Section 5.1
2 Projected renewal expenditures are inclusive of applied 9% administration cost.

The Asset Financial Ratios are as follows:
Ratio Road Assets Target
Asset Consumption Ratio 88% Standard is met if the ratio >50%. Standard is improving if the ratio is between 60% and 75%
Asset Renewal Funding Ratio 68% Standard is met if the ratio is between 75% and 95%. And is improving if between 95% and 105% and ACR is within the range 50% to 75%.
The above ratios indicate that the Coorong District Council Roads Asset Consumption Ratio meets desired standards. The Asset Renewal Funding Ratio indicates that additional funding is required to maintain assets in a Fair condition.
1.5 Action Plan
This Asset Management Plan will be reviewed during annual budget preparation and amended to recognise any changes in service levels and/or resources available to provide those services as a result of the budget decision process.
The Plan has a life of 4 years and is due for revision and updating within 2 years of each Council election.
A detailed Action Plan generated from this Asset Management Plan is shown in Section 6.2.2.

Condition Index
Community Rating Scale
Condition Description
1 Good Only planned maintenance, if any, required
2 Fair Minor maintenance required plus planned maintenance. Consideration may need to be given in following five to seven years to repair or minor renewal of a selected part of the asset.
3 Poor Significant maintenance required. Renewal of part of the asset may be essential within next five years
4 Very Poor Significant renewal/upgrade required within three years.
5 Close to Failure Asset requires immediate renewal or potentially in two to three years, permanent removal from service. Action could be required to prevent public access to the asset and for use of alternative routes.
6 End of Life Asset is not useable and/or obsolete.
2.2.1 Sealed Roads
It is important that adequate funding is applied to the renewal of the surface when required, as this can also have an impact on the rate of deterioration of the pavement.
Also, extreme weather or changed traffic conditions (increased usage and heavy vehicles) can accelerate the deterioration of the road surface and pavement.

3 Levels of Service and Condition Assessment
3.1 Customer Research and Expectations
Council participates in the Local Government Association of South Australia Comparative Performance Measures in Local Government Customer Satisfaction survey. This telephone survey polls a sample of residents on their level of satisfaction with Council’s services (with scores ranging from 1 being least satisfied or least important and 10 very satisfied or very important).
The objectives of this research are to assist Council management in:
Understanding the needs and expectations of residents within the municipality;
Delivery of Council services; and
Evaluating the effectiveness of Council services and programs. Allocating resources across Council services and programs.
When asked to rank the importance of 7 Council asset and infrastructure services, the residents identified their views regarding the services delivered by Council in terms of priority as per the following Table with Comparison to the importance for these services on a State average.
Service Area Council
Importance Score

3.3 Current Levels of Service
Roads service levels have been defined in two ways in this model:
1. Community Levels of Service - relate to how the community receives the service in terms of quality, function/ capacity, safety, and amenity of the facility/ service provided.
2. Technical Levels of Service – deal with parameters such as condition, cost-effectiveness, statutory compliance, and security. These parameters support the community levels of service to ensure that minimum community levels of service are met.
Council’s current levels of service are detailed below.

In regards to Technical Levels of Service the Standards for construction of new roads and associated road infrastructure assets and for the expansion, upgrading and renewal of existing infrastructure, takes the following factors into consideration, when determining design and construction aspects:
Functional classification;
Traffic volume and type;
Percentage of trucks;
Bus routes;
Bicycle Lanes; and
Geometric design parameters to allow for the safe and functional movements of traffic.
Council also utilises the following standards and guidelines to ensure a formalised and consistent approach to asset management:
National and State Engineering design standards;
DPTI Standards;
Design criteria based on asset hierarchy (as documented in Section 3.3.1 and 3.3.2);
Relevant Australian Standards and Guidelines (as documented in Section 3.2); and
Australian Rainfall and Runoff Guidelines.
It is proposed that design standards will be considered on a case-by-case basis. Roads and associated infrastructure assets will generally be designed in accordance with the above standards and guidelines.
3.4 Maintenance & Operational Levels of Service
For the Levels of Service delivered on a day to day nature (i.e. responding to customer requests for maintenance faults and responding to breakdowns), refer to Council’s Roads Levels of Service (Refer to Appendix 1).
This RAMP acknowledges the importance of understanding and monitoring the linkage between workload indicators and intervention actions, as a substantial increase in area of road pavements or footpaths which will need to be maintained, can materially impact upon intervention action (and customer satisfaction and duty of care requirements) if not accompanied by a comparable increase in budget allocation or productivity improvement.
Given the outcomes of the internal and external review with respect to Council’s road and associated infrastructure asset maintenance services, the standards of maintenance detailed in this RAMP are considered reasonable and meeting community expectations in the context of responsible and reasonable road and footpath management.
3.5 Condition Assessment Framework
CDC has a documented assessment manual (Refer to Coorong Council Road Data Collection Manual version 1.0.1 with regards to condition rating the road pavements and surfaces, footpaths and kerbs.

4 Key Achievements
4.1 Asset Management Practice
Actions undertaken by Council, to improve the management of the road assets, include the following.
Ongoing development and review of Asset Infrastructure Management Plans.
Revaluations every four years.
Sophisticated predictive modelling has been used to determine the future road asset renewal funding requirements based on the condition data.
4.2 Operational
Council is continuously monitoring new asset treatments or changes within the industry that may be available to adopt or implement to increase the life of its assets. Technology changes that could affect the delivery of services covered by this RAMP are documented in the following table.
Technology Change
Effect on Service Delivery
Vehicle safety Improved vehicle design and quality will mean that the road condition will become less important as the vehicles will be able to accommodate minor shape loss / deformations better.
Bitumen quality Bitumen manufacturers are constantly developing new products to suit modern day applications to cope with increased traffic volumes, increased solar radiation and environmental cracking. These improvements may mean roads have a longer useful life and require less maintenance over their life.
Trenchless Technologies
By using trenchless methodologies, this will have a better impact on Council’s assets as the soundness of the road and footpath pavements is not compromised when installing new services within the road reserve.
Recycled Materials
By exploring the option of using recycled materials, this will have a dual impact in terms of reduction in greenhouse gas emissions and reduction in initial asset construction costs, thereby enabling more assets to be renewed with the same allocation of annualised funds.
In time, Council will explore these options with regards to the overall impact on this RAMP.

5 Asset Funding Levels
5.1 Forecast 10-Year Funding Required
Predictive modelling and condition ratings were used to determine the following required renewal expenditure over the next 10 years.
Council has developed a decision logic required for use in prediction that identifies the intervention points to trigger treatments for each service criteria (i.e. Linear Cracking, Edge Defects, Overall Condition, etc.). The results of the modelling are shown below in both the predicted funding requirements and the predicted service level. The funding scenario below is the most affordable current scenario.

5.3 Financial Ratios
Asset Consumption Ratio:
This ratio seeks to highlight the aged condition of a local government’s stock of physical assets. If a local government is responsibly maintaining and renewing / replacing its assets in accordance with a well prepared asset management plan, then the fact that its Asset Consumption Ratio may be relatively low and/or declining should not be cause for concern – providing it is operating sustainably.
Asset Consumption Ratio= Depreciated Replacement Cost of Depreciable Assets Current Replacement Cost of Depreciable Assets
Purpose: This ratio measures the extent to which depreciable assets have been consumed by comparing their written down value to their replacement cost.
Standards: Standard is met if the ratio can be measured and is 50% or greater (0.50 or >). Standard is improving if the ratio is between 60% and 75% (0.60 and 0.75).

Asset Renewal Funding Ratio
This ratio indicates whether the local government has the financial capacity to fund asset renewal as required, and can continue to provide existing levels of services in future, without additional operating income; or reductions in operating expenses.
The ratio is calculated from information included in the local government’s Long Term Financial Plan and Asset Management Plan; not the Annual Financial Report. For the ratio to be meaningful, a consistent discount rate should generally be applied in Net Present Value (NPV) calculations.
Asset Renewal Funding Ratio = NPV of Planned Capital Renewals over 10 years NPV of Required Capital Expenditure over 10 years
Purpose: This ratio is a measure of the ability of a local government to fund its projected asset renewal / replacements in the future.
Note: A ratio of between 95 and 105% indicates that the local government’s Long Term Financial Plan makes adequate provision to maintain existing levels of service and renew or replace assets. The 95 – 105% measurement is a suitable target if the Asset Sustainability Ratio falls within the 90 to 100% target and the Asset Consumption Ratio falls within the target range of 50 to 75%. A ratio between 50 and 75% indicates that the local government may not be making adequate provision for the future renewal or replacement of its asset base.
Standards: Standard is met if the ratio is between 75% and 95% (or 0.75 and 0.95). Standard is improving if the ratio is between 95% and 105% (or 0.95 and 1.05), and the ACR falls within the range 50% to 75%.
