Work to start on Coffs Harbour's third flood detention basin

INITIAL works will begin next week on the Spagnolos Rd Flood Detention Basin.

The basin is the third set for construction under Council's Flood Mitigation Program.

The total cost of the construction project is $2.2m. Two-thirds of the cost has been secured through a grant from the NSW Government.

The work involves the construction of a 43,000 cubic metre embankment over a minor stream in the Coffs Creek catchment, with the flow diverted through twin, piped culverts running under the embankment.

The basin is expected to be completed by mid-December, weather permitting.

Council's Flood Mitigation Program began in 2009 and is designed to help reduce the numbers of homes and businesses downstream of Coffs Creek that can be inundated when flash flooding occurs.

The largest of the detention basins, at William Sharpe Drive in West Coffs, was completed in 2010. The Bennetts Road basin was finished in 2012.

"The aim of the flood detention basins is to help alleviate the effects of flooding on homes and businesses in the Coffs Creek area," Council's Director City Infrastructure Services, Ben Lawson, said.

"They can't solve the issue alone, but they will certainly ensure that flood levels in a 100-year flood are significantly lower downstream.

"They work by capturing the water run-off created during a storm event and then releasing it slowly into the watercourse so that the impact of the deluge is reduced downstream."

Rain gauges and water level recorders have also been installed at a number of key locations across the local government area.

The recording and radio communication systems are fully operational and the data is provided directly to the Bureau of Meteorology and State Emergency Services.

Council has had very positive feedback regarding the assistance this provides the emergency services.
