Lavington Catchment - Flood Risk Scoping Study

Albury City Council (ACC) commissioned a Flood Risk Scoping Study of the Lavington catchment in order to determine the nature and extent of flooding in the catchment. The study estimated flooding under current conditions in the catchment and floodplain. Flooding was assessed for the 20% and 1% Annual Exceedance Probability (AEP) events and also for the Probable Maximum Flood (PMF). The Study has been jointly funded by the NSW Department of Environment and Climate Change and the Albury City Council.

The study catchment lies within the Albury City area to the east of the Albury Central Business District. The catchment is approximately 13.4 km2 in size and includes three main drainage waterways; the Eastern Drain, the Western Drain and the Battenfields Drain. The Eastern Drain has 3 sub-branches that contain small retarding basins.

The key objective of this study was to determine the nature and extent of the existing overland flood behaviour for the Lavington Drain catchment. Specifically, flood behaviour for the 1% Annual Exceedance Probability (AEP) event, 20% AEP event and the Probable Maximum Flood (PMF) was identified. Information on flood levels, velocities and flows were produced based on existing catchment and floodplain conditions. Mapping of the 1% AEP flood extent is also assessed.

The study focus is on overland flooding on and adjacent to the main catchment drainage channels and does not include a detailed assessment of the catchment's piped stormwater drainage infrastructure.

Additionally it is understood that the models developed for the study will provide a tool that may be used for future assessment of development and mitigation options where appropriate.
