Wagga City Council has said it expects to receive a draft copy of a review of its flood levee plans within the next week, which will be examined at a Flood Risk Management Advisory Committee meeting in early July.

The council agreed a year ago to the third-party "peer review" of an independent flood risk management plan, after community pressure from North Wagga residents who want a levee to protect their suburb from one-in-100-year floods.

NWRA treasurer Fiona Ziff wrote to the council's general manager, Peter Thompson, yesterday asking him - "in the interests of transparency" - to delay any decision on the review until new councillors are potentially elected and a fresh flood advisory committee is chosen.

Ms Ziff said there would only be about six days between councillors potentially making a decision on the peer review and the council going into caretaker mode.

"We firmly believe that it is inappropriate to have the current councillors and committee members, who were responsible for approving the allegedly flawed 2018 flood report, deliberate over what conclusions, if any, should be adopted from the peer review," she wrote to Mr Thompson.

"There is a clear conflict of interest here, and as such residents have no confidence that due process will occur."

Ms Ziff believes the council has been "quite negligent" towards North Wagga and said she would consider working with a new council to overturn any decision made on the levee in this current council term.

The levee issue is controversial among North Wagga residents because the rest of the city is afforded the higher one-in-100-year flood protection.

The Daily Advertiser sent questions to council, but a spokesman said they needed time to prepare and send their response to Ms Ziff before making a statement to the media.
