Potential plans for future flood defences in Dumfries would see the whole of the area between the town centre and the River Nith redeveloped.
The flood prevention scheme could cost up to £4 million and would be funded by the council and the Scottish Government.
The Labour group on Dumfries and Galloway Council will ask for detailed plans to be drawn up within six months at the planning meeting.
Any plans would then need to get planning permission and the scheme could take up to three years to complete.
The scheme would involve a green bank barrier being built along the River Nith at the Whitesands, which would reach a height of two metres at its highest point.
That would protect against most flooding but not against a severe flood described as a "one in two hundred year event".
