Earth embankments and walls are part of an Office of Public Works plan to safeguard Glanmire where residential and commercial premises alongside the Glashaboy river sustained flood damage.
Minister with responsibility for the OPW, Sean Canny will detail the plans later this month.
Cork County Council confirmed the minister will unveil the scheme as a public exhibition on the project at the Vienna Woods Hotel in Glanmire on November 21.
The scheme has been drawn up by county council engineers and consultants Arup and JBA on behalf of the OPW and was prompted by serious flooding which hit the area on June 28, 2012.
The flood caused damage in an area encompassing Sallybrook, Hazelwood, Riverstown and Glanmire village.
Flood relief project manager Colm Brennan, an acting senior engineer with the county council, said the plans primarily included the building of earth embankments and walled defences along the length of the river from Sallybrook to the Glashaboy estuary.
He said a new bridge will be installed between the Hazelwood and Crestfield shopping centres which would help ease water backing-up.
There will also be a number of pumping stations provided at strategic points as an additional means of diverting water at critical locations.
The council said the preliminary start date for any flood relief works on the project is towards the end of 2017.
Furthermore, the estimated completion of the work could take up to two-and-a-half years.
While the area has not experienced a repeat of the 2012 deluge, further damage was caused on December 29/30 last year when torrential rain again caused flooding.
Storm drains overflowed in Meadowbrook and threatened a number of houses, until the fire brigade which had been inundated with call-outs, eventually arrived with pumping equipment.
However, a number of families in the Copper Valley View and Marwood had their homes flooded.
In the interim, the local authority undertook some remedial works. The county council, in conjunction with Inland Fisheries Ireland (IFI), carried out river cleaning in the Glashaboy from the shopping centres downstream to Meadowbrook and to the southern side of Riverstown bridge.
There was a setback to the preliminary works when the destructive invasive plant Japanese Knotweed was discovered in the area. Contractors had to be engaged to control it spreading.
Mr Brennan, meanwhile, said he expected the public exhibition to be held on the opening day at the Vienna Woods Hotel from 2pm-8pm. Local councillors and TDs will be given an advance briefing.
He said council engineers and representatives from the consultants, and OPW, would be available to answer any queries from the public.
It is envisaged the public exhibition will continue for three to four days.
Details of the project will remain available at the local library and council offices.
