SMOOTH CYCLING: More than 200m of concrete was poured in the second week in October atop the new section of levee bank constructed along Kooringal Rd. The new three-metre width path starts at Cemetery Road and will eventually link up with the existing cycle path at Copland Rd. The new pathway will be open by the end year when construction works are scheduled for completion.

August 2018

  • Construction on a new 800m section of levee is underway near the Monumental Cemetery on Kooringal Road.
  • The existing levee - directly opposite the Exhibition Centre Netball Courts - will be reinforced, widened and a 130m concrete spillway built as a flood mitigation protection.
  • Head walls on either side of Copland Street are also under construction. In the event of a major flood additional temporary barriers are locked in to these strong structures to secure the levee.
  • This stage of the levee project is scheduled for completion by January 2019.

Residents should be mindful of increased truck movements at the Kooringal Road/Copland Street site during construction.

Levee works at Kooringal Rd

FLOOD PROTECTION: Wagga Wagga City Council’s Senior Project Manager Darryl Woods and Project Coordinator Graham Cox review plans for the section of new levee under construction on Kooringal Road.

June 2018

  • The contract for the remaining $1.14M of Stage 1 works was awarded to local company Burgess Earthmoving to complete Stage 1 of the Main City Levee upgrade from Copland Street, including the spillway, through to the Monumental Cemetery.
  • The initial Stage 1 contractor, Central West Civil, has completed its component of the project.
  • The tender package for Stage 2 was released on 29 June.

May 2018

  • Sheet piling is installed along a 30-metre stretch of the levee bank to demonstrate what is to come as a part of Stage 2 of the upgrade.
  • The process involves driving steel sheets approximately four metres into the ground to create a wall along the levee bank that is approximately a metre high and achieves a 1 in 100 year level of protection against flooding.

DEMONSTRATION WORKS: Sheet piling will occur where there is limited space on the existing levee and not enough room to use earth to raise the height of the levee.

March 2018

  • Construction on the Main City Levee upgrade continues following successful discussions between Wagga Wagga City Council and contractor Central West Civil.
  • A deed has been signed to vary the scope of works that Central West Civil was initially contracted to complete. Under the deed, Central West Civil will resolve issues with existing work and complete the Flowerdale downstream spillway.

November 2017

Works undertaken to date to raise and strengthen the Main City Levee include:

  • Tree and top soil removal at the Flowerdale section
  • A total of 48,000 tonnes of clay has been stockpiled on site in preparation for reshaping and reconstruction of the levee
  • Preparation works for the construction of a new concrete spillway at Flowerdale will start in the new year
  • Works have also started at the Kooringal Road/Copland Street end of the levee.

Residents should be mindful of increased truck movements at both the Flowerdale and Kooringal Road/Copland Street sites during construction.

MAKING PROGRESS: Director Commercial Operations Caroline Angel, Mayor of the City of Wagga Wagga Councillor Greg Conkey and Senior Project Manager Darryl Woods inspected the works currently underway at the Flowerdale section of the Main City Levee upgrade.

DIGGING IN: Stage 1 works have so far included tree and top soil removal at the Flowerdale section in preparation for reshaping and reconstruction of the levee.

October 2017

Central West Civil starts site preparation at Flowerdale Lagoon end of levee. During the first week residents will see temporary fences erected and various preparation works completed, including surveying and setting out of the work site. By mid-October heavy machinery, such as graders, diggers and trucks, will be working on site.

During construction of the levee upgrade some sections of the Wiradjuri Walking Track, which runs alongside the Murrumbidgee River, will be subject to temporary closures.These closures are to allow for the safe construction of the levee upgrade.Closures of the walking track associated with the Main City Levee upgrade are:

  • Flowerdale Lagoon – closed for duration of project (October 2017 – April 2018)
  • Copland Street/Kooringal Road roundabout to Monumental Cemetery – closed from 1 November 2017 to February 2018

Residents are also reminded to be mindful of a larger-than-normal number of truck movements in the Flowerdale and Narrung Street areas during the works.

All dates are subject to weather and works and any additional interruptions will be advertised accordingly.

WORK PREP: At the end of October thousands of cubic metres of dirt was moved to Flowerdale in preparation of the levee upgrade.
