Ms Fitzharris: The answer to the member's question is as follows:

(1) The ACT Government is in the process of revising and upgrading the flood modelling for the 1% Annual Exceedance Probability (AEP) mapping (previously referred to as 1 in 100 year flood events) for eight catchments across the ACT. Ginninderra is one of these catchments. Once this mapping and analysis is completed it will be used to inform relevant land use planning decisions and flood mitigation work.

(2) Until the flood modelling and consequential design of flood remediation work is completed it is not possible to provide a response to this question.

(3) Until the flood modelling and consequential design of flood remediation work is completed it is not possible to provide a response to this question.

The timing and delivery of the remediation works will be subject to the outcomes of the modelling and design work.

(4) The ACT is committed to the five steps of National Best Practice flood risk management, as identified by the Australian Emergency Management Institute.

The above mentioned 1% AEP maps define the nature and extent of flood risk. Once priority areas have been identified, the Government will work collaboratively with the community to develop Flood Management Options Studies that will identify the mitigation options from an economic, social and ecological perspective.

(5) Cost estimates cannot be determined until flood modelling and consequential design of flood remediation work is completed.
