The municipality of Kingborough is located in southern Tasmania. It is predominantly rural in nature with 49% (265 kilometres) of the road network being unsealed. Having one of the highest population growth rates in Tasmania over the past 30 years the ratepayers of Kingborough are increasingly asking Council to upgrade unsealed roads to a sealed road standard citing improved road safety and reduction in dust as the most common reasons for their requests.

Kingborough Council does not have a strategy or policy for assessing the merits and long term costs of upgrading unsealed roads to a sealed road standard. Kingborough requires a procedural document which sets forth guidelines and a measurement system appropriate for its climate, topography, geology, ecology, road design standards and limited financial resources to allow staff to appropriately analyse the viability of community requests for sealing unsealed roads.

Six key roads were selected for having either considered high traffic volumes (greater than 200 vehicles per day), steep topography, increased residential density or high crash history. Assessments were conducted on each road including traffic counts, geometric analysis and crash analysis based on a preferred scoring system. A cost-benefit analysis was undertaken to compare current annual maintenance requirements with the economic benefits of upgrading the unsealed roads to a sealed standard.

A key outcome of this project was to research other Local Government policies and procedures with respect to upgrading unsealed roads to allow an engineering assessment to be completed. Another key outcome was to complete a cost-benefit analysis to compare the long term costs of maintaining an unsealed road with the long term costs of upgrading and maintaining a sealed road. The results of the project will assist Council in the development of a strategy and policy in the future.
