Numurkah Flood Study expands study area
Publish Date: 03/06/2016
The study area for the Numurkah Flood Study has been expanded to better understand the potential impact of the community’s preferred flood mitigation options.
Moira Shire’s General Manager Infrastructure Andrew Close said, “Last year the community indicated a strong preference for a ring levy around the entire Numurkah township. Before we can finalise this option in the report we have to investigate the extent of all possible impact for properties, homes and businesses outside the levy.”
The expanded area covers a much larger footprint compared with the original study area and extends south to Wunghnu and north toward Katunga.
With support from local member Suzanna Sheed, Council secured $50,000 of additional funding from Department of Environment, Water, Land and Planning (DEWLP) to fund the investigations and modelling.
Mr Close said the investigations had included some high-tech options.
“Aerial surveys have provided accurate land levels - on such a large and flat flood plain even small differences can have a significant impact on understanding where the water will flow,” said Mr Close.
The survey work was completed earlier this year and the data is now being interpreted and verified.
“Once we have the data we can model the potential impact and resume our conversation with the Numurkah community, the GBCMA, DEWLP and the study consultants about the options for improving local flood mitigation,” said Mr Close.
Mr Close said Council was continuing to meet with the Numurkah Flood Reference Group to keep members updated on their progress and to test alternative solutions as they are identified.
Mr Close said that while some options require further investigation, Council was already making provision in its proposed 2016/17 budget to install flood gauges at key sites identified in the Numurkah Flood study.
“The gauges will provide more information to improve flood planning as well as improving the early warning for flood events,” said Mr Close.
Mr Close said Council hoped to finalise the study soon but emphasised the importance of ensuring the proposals could stand up to community and potential funding scrutiny.
