Over €6.5m in funding has been approved for eight local authorities across the country to introduce interim flood protection measures.
The once-off funding has been allocated in response to Storm Chandra.
The low-pressure system brought strong winds and heavy rain in January, particularly impacting the south-east of the country.
Wexford and Kilkenny county councils are to receive the majority of the funding, over €2.6m and €1.1m respectively.
Other local authorities to be allocated money include Louth County Council, which was given almost €699,000, and South Dublin County Council, receiving €659,000.
Dublin City Council was allocated more than €591,000, Carlow County Council was given almost €484,000, Wicklow County Council received over €332,000, and Waterford City and County Council was given more than €151,500.
Minister of State for the Office of Public Works, Kevin 'Boxer' Moran, made the announcement after meeting the local authorities in Dublin.
He said that he wanted the funding spent and measures delivered by the end of this year.
Mr Moran also said that he would soon be extending the threshold for a separate scheme to allow all local authorities to better plan and implement solutions to flood risk.
Asked about specific measures, Mr Moran said the impact on Enniscorthy in Co Wexford had been significant.
"It's a town that's very impacted with flooding over the years.
"This will give interim measures to help those local authorities, but also help the community and the business that's been badly affected by this.
"It's about us all collaborating and working together, and to see now the implementation of those measures that I put in place today, to see them at the end of the year."
Mr Moran said that many of the measures would not require planning.
"They're measures that can be done almost instantaneously, and that's what we're pushing, to make sure that's done."
The minister said the announcement was separate to the emergency supports put in place in the aftermath of the storm and businesses should reach out if there is any blockage in that system.
He added that long-term solutions and insurance cover are being considered.
"We are looking at the long-term solutions, which is building the defences for the towns up and down the country.
"Last year, we hit a record of €102m. I want to even go further this year to spend that money, because I know as minister, that's my job.
"There's people out there after, I suppose, spending weeks getting their house back to where it is. They want assurance that this won't happen again."
Wexford County Council's Deputy Chief Executive Eamonn Hore said that he was "delighted" the measures could be put in place in Enniscorthy, as well as Bunclody, Bridgetown and Wexford town.
Mr Hore said: "We put forward a detailed scheme, and everything we looked for has been funded, which is great."
He said the money would be spent on flood barriers, natural protection banks, and individual property protections, adding that the plan is to start the work immediately.
