(5) The pool forecourt improvements have been designed by a professional landscape architecture consultancy in accordance with all applicable safety standards for temporary installations in a public place. A Design Safety Assessment was undertaken as part of the design. It should be noted the bicycle racks were relocated in late November 2019 closer to the Dickson Pool entrance for the convenience of pool visitors to increase utilisation.
Canberra—flood management
(Question No 2832)
Ms Le Couteur asked the Minister for Planning and Land Management, upon notice, on 29 November 2019:
(1) Does the ACT Government have a figure for the total storm damage claims made to insurance companies as a result of the 25 February 2018 storm.
(2) How much of the flooding that took place in North Canberra east of Northbourne Avenue as a result of the 25 February 2018 storm was riverine flooding and (a) what other factors contributed to the storm damage in that area and (b) did overland flows account for the majority of damages to private property.
(3) To what extent has climate change and the percentage of impervious area in the catchment been factored in to the latest flood maps for the Sullivan’s Creek Catchment (e.g. those used for the Section 72 renewal process and those available on ACTMapi).
(4) Is the ACT stormwater system digitised to the quality required for flood forecasting; if not, are there any plans to do so.
(5) In the Section 72 Dickson plan for proposed services, the consultants have assumed a future capacity. How many apartments in total will the duplicate trunk sewer line and other service upgrades cater for.
Mr Gentleman: The answer to the member’s question is as follows:
(1) No, the Government does not record or otherwise have access to private insurance claims made by Territory residents.
(2) Flooding was caused by a combination of riverine flooding (from Sullivans Creek and major tributaries) and overland flows between properties, streets and other land uses. Partial blockage of some systems was also a factor but is not unusual or unexpected.
As the ACT Government only has records of what damage occurred on public land, it would be hard to make a definitive comment on the damage caused to private property. Despite the storm being very large (estimates vary up to a once in one thousand year rainfall event for some areas) the public stormwater system coped well overall with minimal damage.
(3) Flood studies are done in accordance with Australian Rainfall and Runoff (ARR). ARR has techniques for dealing with the impact of climate change. Impervious surfaces are included in the flood modelling by calibrating flood models to actual
