Foreshore improvement works, Tanunda Drive, Rivervale

The Western Australian Planning Commission (WAPC) has contracted Western Australian civil construction firm MMM WA Civil to undertake major remediation works along the Rivervale foreshore near Tanunda Drive, commencing in September 2019.

A limestone wall extending approximately 170 metres along the river foreshore and about 12 metres into the river will be constructed, with the project to be completed within a year.

The structure will help stabilise this section of foreshore and protect the steep embankment from deterioration over time.

This preventative measure is focused on long-term community safety and has been informed by expert, independent testing and analysis.

The following works will take place:

  • a section of the bike and footpath along Tanunda Avenue will be closed and remain closed for the duration of the construction period
  • an alternative path will be established during this stage and traffic management put in place to maintain safe access
  • ground preparation will be undertaken
  • a temporary pathway down to the river’s edge will be constructed to allow for authorised construction vehicle access
  • materials will be brought to the site via temporary vehicle access pathway
  • large limestone rocks will be placed using heavy equipment
  • the riverbank will be rehabilitated with native vegetation and these will be managed until the river escarpment and construction path are fully restored.

Signage will be placed where necessary to advise residents and river users of temporary pathway closures and access restrictions due to the works.

The WAPC is working with the City of Belmont, Department of Biodiversity and Conservation, and the South West Land and Sea Council on this important remediation project.

Fast facts

What is happening at the foreshore near Tanunda Drive in Rivervale?

Major remediation and improvement works will be taking place along the foreshore adjacent to Tanunda Drive in Rivervale.

Western Australian civil construction firm MMM WA has been contracted to construct a limestone rock wall that will extend approximately 170 metres along the river foreshore and about 12 metres into the river. They will also undertake slope stabilisation works to both strengthen and reduce the steepness of the escarpment. 

Works are proposed to begin in Spring 2019. See the project site drawings.

 
Why do these improvements need to happen?

These essential, preventative works are designed to preserve this section of foreshore for the long-term. The rock wall and stabilisation works will bolster, reinforce and protect the extremely steep embankment from deterioration over time. The solution being put into action has been informed by expert, independent testing, monitoring and analysis. These improvements will ensure the community can continue to safely enjoy the place, and provide peace of mind for local residents, businesses and property owners.
 

How will I be affected?
Cyclists and footpath users

A section of the foreshore path between the apartments and the river will be closed and remain closed until the project is complete. An alternative route for pedestrians and cyclists will be established during this stage and traffic management put in place to maintain safe access.

Bilya Kard Boodja lookout and park users

A portion of the park will be closed to the public, as this area is required for construction access. Measures will be put in place to protect trees in this area. Paths, turf or other park infrastructure impacted by the works will be restored at the completion of the project.

Residents

While every effort will be made to minimise disruption and inconvenience to residents, there may be some noise associated with the works. Measures will be put in place to minimise the amount of dust created. Generally, works will take place between 7am and 6pm, Monday to Friday. 

Signage will be placed where necessary to advise residents and river users of temporary pathway closures and access restrictions due to the works.

The natural environment

A Construction Environmental Management Plan (CEMP) will be prepared to ensure that potential environmental impacts are identified and managed appropriately. The plan will include measures to protect vegetation and wildlife, sediment management, site access, waste management and protection of the river. 

Following construction works, the site will be rehabilitated and planted with suitable native species. Ongoing monitoring and maintenance will be undertaken post construction to ensure that plants are successfully established.

What will the project involve?
  • Ground preparation, mainly involving the removal of vegetation.
  • A section of the foreshore path between the apartments and river will be closed and remain closed for the duration of the project.
  • An alternative route will be established, and traffic management put in place to maintain safe access.
  • A temporary pathway down to the river’s edge to allow for authorised construction vehicle access will be constructed.
  • Materials will be brought to site via temporary vehicle access pathway requiring closure of part of the adjacent park (Bilya Kard Boodja Lookout).
  • Large rocks will be placed using specialist machinery and equipment.
  • The steep slope will be significantly levelled and stabilised, using fill and vegetation.
  • The riverbank will be revegetated with native plants and trees which will be managed until the river escarpment and construction path are restored.
  • Bilya Kard Boodja lookout and park area will be restored.
  • The reintroduction of native wildlife, where feasible, once the area becomes habitable.
Who is involved in the project?
