Bypassing another flooding incident
JIM Limbert wants to see a drainage bypass to help Coffs Creek cope with flash flooding.
The prominent senior Coffs Coast resident outlined a number of suggestions for flood mitigation work in Coffs Harbour during his address to Coffs Harbour City Council on Thursday.
Mr Limbert told councillors it was his second attempt to push for similar changes.
“Before the flood in 1996 I warned council during my five minutes that Coffs Harbour was in imminent danger of being flooded and suggested a few changes that would lessen the depth of the flood,” Mr Limbert said.
“I was not surprised that nobody took me seriously.
“I am now warning the council that there will be much bigger floods in the future, possibly the near future.”
He said while retention ponding was arguably the most viable solution, an additional scheme was needed to prevent the ponds being overwhelmed by extreme and prolonged weather conditions.
Mr Limbert proposed creating a short cut which would allow some of the water flowing into Coffs Creek to be diverted into massive pipes underneath the historic cemetery and Botanic Garden.
The water would be discharged back into the creek lower down, close to the eastern end of Coff Street, bypassing a large loop of the creek.
Mr Limbert also suggested extra pipes at the two main Coffs Creek bridges; bypass piping south of the highway near Isles Drive plus upstream retention ponding and dredging sand build-up in both Coffs and Boambee Creeks.
