WORK to enlarge the Coffs Harbour Boat Ramp basin to stop wave surges is due to start on Monday.
At the same time as the boat ramp works, Coffs Harbour City Council will also carry out additional road upgrade works along Jordan Esplanade from Camperdown St to the Public Works compound on Corrambirra Point.
The basin enlargement is financed by a $1million grant from Roads and Maritime Services, while the road upgrade has been paid for through council's 2014-2015 special rate variation.
The modelling for the boat ramp expansion was undertaken by Manly Hydraulics Laboratory, which found expanding the boat ramp basin would reduce wave surge by about a third.
The boat ramp will still be accessible during works.
