Twenty four areas in Dublin are at significant risk of flooding unless there's investment to stop storm damage.
That's according to a new report from the Office of Public Works.
It has finalised a list of 300 towns across the country at risk of flooding.
In Dublin the list includes Balbriggan, Baldonnell, Donabate, Dublin city, Lucan, Santry and Swords.
It's estimated that 1 billion euro is needed over the next decade to carry out all necessary works.
Since 2000 an estimated 700 million euro has been paid out by insurance companies for 8 major flooding events that ravaged parts of the country.
