The Whitesands project is based on the development of a raised and landscaped walkway along a flood-prone section of the river.
At last estimate the cost of the scheme was £37m.
The local authority said the project would offer flood defences for properties in the area and create a vibrant riverside experience.
However, opponents have said it could damage the character of the waterfront, hit tourism and trade and reduce parking.
They have called on the council to drop the project entirely and spend money on town centre regeneration.
The latest chance for the public to have their say will be on Tuesday and Wednesday at The Standard building on Dumfries High Street.
Feedback received will be used to further develop plans for the waterfront area.
