Village Flood Studies

The Tarcutta, Ladysmith and Uranquinty Floodplain Risk Management Studies and Plans have been prepared for the three towns to investigate and manage flood risk.

Tarcutta, Ladysmith & Uranquinty Floodplain Risk Management Studies and Plans (VOFFS)

This report describes the data collection, model update, flood risk assessment and mitigation measures assessment of the Tarcutta, Ladysmith & Uranquinty Floodplain Risk Management Studies and Plans (FRMS&P).

The study, which has been undertaken by GRC Hydro on behalf of Wagga Wagga City Council, follows on from the Tarcutta, Ladysmith and Uranquinty Flood Studies, completed in late 2014, which themselves were in response to the significant flood events of 2010 and 2012.

This study comprises stages 3 to 4 in the five-stage process outlined in the NSW Government’s Floodplain Development Manual (FDM, 2005) (DIPNR, 2007).

These works include:

Data collection – collection of all applicable data to be used for the ensuing stages of the studies;
Flood Study – a comprehensive technical investigation of flood behaviour that provides the main technical foundation for the development of a robust floodplain risk management plan;
Floodplain Risk Management Study (FRMS) – assess the impacts of floods on the existing and future community and allows the identification of management measures to treat flood risk;
Floodplain Risk Management Plan (FRMP) – outlines a range of measures, for future implementation, to manage existing, future and residual flood risk effectively and efficiently; and
Plan Implementation – once the management plan is adopted, an implementation strategy (devised in Stage 4) is followed to stage components dependent on funding availability.

Following the completion of the FRMP Council will begin implementing its recommended measures and will review the plan periodically.

The FRMS&P investigates flood risk in the three towns, and will inform the Council flood planning processes, and recommend a number of flood risk mitigation measures in the Floodplain Risk Management Plan.

The report contains the following sections:

Background – description of the three study areas, overview of relevant policies and legislation and available data.
Overview of Flood Behaviour – methodology and results of Australian Rainfall and Runoff 2019 (ARR2019) model updates.
Flood Risk Assessment – Separate section for each town including flood hazard, hydraulic categories, levee function, flooding hotspots, flood warning and emergency response
Flood Risk Mitigation Measures – description of the approach to flood mitigation and assessment of options in each town.
Community consultation undertaken during the project
