More levee works to get underway this year

The second stage of one of the city’s most important infrastructure projects, the Main City Levee Upgrade, will get underway this year after Council tonight agreed to enter into a contract with the preferred tenderer.

Mayor of the City of Wagga Wagga Councillor Greg Conkey OAM said discussions will commence with the preferred tenderer and contracts should be exchanged in November.

“The $9.6M stage 2 works account for a significant portion of the entire $23.2M levee upgrade which is being funded by all levels of government, and will offer a greater level of assurance to Wagga Wagga residents and businesses,” Cr Conkey said.

“The levee upgrade has been a long and detailed project due to its complexity and importance and I’m pleased to see it progressing to the second stage, noting that Stage 1 is due for completion in December.”

Construction methods to be used to raise the levy height in Stage 2 will comprise predominately of capped sheet piles that will protrude from the earth levee running the length of the Cadell Place wall (parallel to Fitzmaurice Street) to Johnson Street, then from, Riverina Playhouse to Hammond Avenue.

In addition to the sheet piling, raising and extending the existing concrete retaining walls along Cadell Place and behind Watermark apartments, will also be part of this stage.

The works, which are expected to begin in December, will be higher in visibility in comparison to Stage 1 due to the proximity of construction sites to the CBD and residential areas located along the Murrumbidgee River.

A community meeting to explain the Stage 2 project and the potential impacts to residents and businesses during construction will be held in late November.
