Project 18640 – Wagga Wagga Villages Floodplain Risk Management Study and Plan
Steve Gray from GRCHydro made a presentation to the committee providing an overview of the proposed villages overland flow investigation which is about to commence. The villages to be considered as part of this report include Tarcutta, Ladysmith and Uranquinty.
Normally the investigation would be a five step process, but completion of the recent major floodplain study will allow this project to start directly with the study and plan aspects.
An update of the Australian Rainfall and Run-off manual (AR&R) was finalised in 2016. This will require a review of the major floodplain study to determine any impacts in relation to the locality of the three villages.
An initial understanding of overland flow impacts within the three villages is as follows:
· Tarcutta – Limited number of properties affected
· Uranquinty – Has internal overland flow issues
· Ladysmith – There is little impact from Kyeamba Creek flow with a minimal number of properties affected. Has probably the lowest hazard level of the three villages.
Community consultation to be undertaken in 2019. Critical to discuss and disseminate flood issue outcomes.
Sam Robins – planning issues relating to controls surrounding overland flow v versus riverine flooding – freeboards. “Everyone wants a shed” issue – knock on effect. Undertaking a $5k study for a $4k shed not ideal.
Cr Kendall – Suite of options for Risk Management. Analyse all properties having an impervious area (shed) to show flow on effect.
Steve Gray – good idea to help understand effects
Brian Mahony – already seeing effects of Uranquinty growth with regard to overland flow. Uranquinty modelling seemed ok - detail showed some issues.
Darryl Woods – What level for Sandy Creek in the Study?
Steve Gray – Not sure yet, Uranquinty could be peak/peak
Cr Kendall –Study could have insurance implications.
Steve Gray – Risk Management mitigation options could include:
§ Structural – deflect water – Building Control review
§ Voluntary Property Purchase
§ Raise Houses
§ DCP Controls
§ Response measures – Early warning
§ Review suggestions from Community then rank them
Caroline Angel – Will require information from the other communities as well
Suggestion – consider subcommittee groups to be setup
