Residences in and around the Rocky Ponds Creek and Showground Creek areas have been requested this week to respond to a mail-out questionnaire addressing historical occurrences and the details surrounding the event.
“What we are ideally looking for is specific heights and dates to be later cross-referenced with relative rainfall records.” Mr Appleby said.
Aiming primarily at addressing the potential risk in 100, 10 and five year floods, Mr Appleby said the survey will provide critical information for analysis by council’s independently-contracted consulting engineers HydroStorm Consulting Pty Ltd in assessing the risks of urban flooding and in developing pre-emptive risk assessment plans.
“It will enable us to assess the risk of flood in newly-developed and developing areas.” Mr Appleby said.
The questionnaire comes after detailed aerial Lidar surveys were conducted in 2009 towards the development of a detailed 500mm contour plan of the catchment area. As independent consultants collate and analyse collected data, Mr Appleby said the information will progress the area’s flood risk management to state government standards.
