*HAVE YOUR SAY - RIVERVIEW DRIVE RECONSTRUCTION

Riverview Drive in Berri, from Clarke Road through to Martin Bend Drive, suffered damage as a direct response to building a precautionary earthen levee during the 2022/23 River Murray flood.

The 2022/23 River Murray flood was the second largest flood in 152 years. At the peak of the flood in late December 2022, the water reached 16.7 metres AHD (Australian Height Datum) in the vicinity of Riverview Drive. At this level, the water did not engage with the levee. However, the levee was required to a minor extent in order to provide freeboard (a gap to account for wave action).

Since the flood, the levee has been removed and Riverview Drive has been reopened to traffic. The road currently comprises a bitumen lane and a road base lane, meaning the speed limit has been restricted to 25 kilometres per hour.

Option 1 - RECONSTRUCTION

• A like for like reconstruction of Riverview Drive, as it was prior to the flood.

Option 2 - ENHANCEMENT

• A like for like reconstruction of Riverview Drive, as it was prior to the flood.
• Plus a 500 millimetre lift on the existing road height.

Option 3 - UPGRADE

• A like for like reconstruction of Riverview Drive, as it was prior to the flood.
• Plus a 500 millimetre lift on the existing road height
• Plus the addition of a walking/bike trail.

How is this project being funded?

Option 1 - RECONSTRUCTION

• A like for like reconstruction of Riverview Drive, as it was prior to the flood.
• Total cost = approximately $860,000

Funding Breakdown: $860,000:

• The South Australian Department of Treasury and Finance (DTF) would contribute approximately 70% of the like for like reconstruction cost, which is approximately $600,000.
• Council would fund $250,000 from an existing Riverview Drive capital project.
• Council would fund $10,000 from its Local Roads and Community Infrastructure Program (LRCIP) (the remaining $280,000 of the LRCIP can be used for other roads and infrastructure)

  Option 1 has no funding shortfall.

Option 2 - ENHANCEMENT

• A like for like reconstruction of Riverview Drive, as it was prior to the flood.
• Plus a 500 millimetre lift on the existing road height.
• Total cost = approximately $1,600,000

Funding Breakdown for the $1,600,000:

$860,000 for the like for like component:

• DTF would contribute approximately 70% of the like for like reconstruction cost, which is approximately $600,000.
• Council would fund $250,000 from an existing Riverview Drive capital project.
• Council would fund $10,000 from its Local Roads and Community Infrastructure Program (LRCIP).

$740,000 for the 500 millimetre lift 'betterment component':

• DTF may choose to fund 50% of the 500 millimetre betterment component, being $370,000.
• Council would fund an additional $280,000 from its Local Roads and Community Infrastructure Program (LRCIP).

Option 2 leaves a funding shortfall of between $90,000 and $460,000 depending on whether DTF chooses to fund the betterment component. This shortfall would need to either be funded by additional Council revenue or future grants (currently unsecured).

Option 3 - UPGRADE

• A like for like reconstruction of Riverview Drive, as it was prior to the flood.
• Plus a 500 millimetre lift on the existing road height.
• Plus the addition of a walking/bike trail.
• Total cost = approximately $2,400,000

Funding Breakdown: $2,400,00

$860,000 for the like for like component:

• DTF would contribute approximately 70% of the like for like reconstruction cost, which is approximately $600,000.
• Council would fund $250,000 from an existing Riverview Drive capital project.
• Council would fund $10,000 from its Local Roads and Community Infrastructure Program (LRCIP).

$740,000 for the 500 millimetre lift 'betterment' component:

• DTF may choose to fund 50% of the 500 millimetre betterment component, being $370,000.
• Council would fund an additional $280,000 from its Local Roads and Community Infrastructure Program (LRCIP).

$800,000 for the walking/bike trail component:

• Council has not budgeted for these works and there would be no DTF contribution, meaning this component is completely unfunded.

Option 3 leaves a funding shortfall of between $890,000 and $1,260,000 depending on whether DTF choses to fund the betterment component. This shortfall would need to either be funded by additional Council revenue or future grants (currently unsecured).
