Residents to help Rockhampton council map flood risk
RESIDENTS are being encouraged to record data from significant storm events as the Rockhampton Regional Council prepares to release its local creek catchment flood studies.
It is the first time creek catchments have been formally modelled, and properties identified in the studies have not previously been identified in council's flood mapping.
Completed on catchments in North Rockhampton and Gracemere, the studies will be used to shape future development in and around creek catchments.
They will also form the basis for future flood risk assessment and mitigation strategies to be undertaken in accordance with council's draft flood management strategy.
Rockhampton Mayor Margaret Strelow said the council had used hydrological models and engaged engineers to map the creeks and determine where water went in storm events.
"We have then tested that against what locals have told us, particularly about the 2013 storms, and had that further tested by another team of engineers," she said.
"This is our beginning point but we had to draw a line in the sand and say, 'this is as good as we can get it on the information we have', and start to shape development in our creek catchment areas to protect residents."
Cr Strelow recognised it was not perfect, but was confident the detail would get better with time.
"We appreciate there will be further work to do," she said.
"We will be asking residents to gather data for us if there's a significant storm - snap photos, get video footage, mark what you can and record rainfall.
"We can gather that data and get these maps refined as quickly as possible."
The council will write to property owners and also run an online community feedback register.
