Armidale - Flood Mitigation Study December 1999

The Armidale Flood Mitigation Study analyses the effects of flooding on all buildings within the floodplains of Dumaresq Creek, Martins Gully, Black Gully and Unnamed Gully.

The Armidale Flood Mitigation Study has resulted in the updating of the hydrological model (RORB) and the conversion and updating of the existing HEC-2 hydraulic model to the latest available software, HEC-RAS. These Models are now available for use by Council to determine the effects of proposed or actual alterations to the floodplain.

The Study has used the updated hydrological and hydraulic information to identify flood liable properties in Armidale. The Study also provides options for reducing the probability of inundation of properties. Options considered include localised channel improvements, property protection and voluntary purchase schemes.

In total, the Study has concluded that 30 residential and 20 commercial premises are affected by the 1% AEP flood. The Study recommends that flood mitigation measures be pursued for 8 of the residential and 2 of the commercial premises, and that management responses be pursued for other flood affected commercial properties.
