The Government has launched a website which will allow users to check if any area around the country is at risk from flooding.
The website, www.floodmap.ie, has been set up for the Office of Public Works.
Visitors to the website will be able to check any street or townland around the country to check if it has been flooded in the past.
It gives information including newspaper clippings, reports and photos of previous floods in each area.
It can be used as a tool by developers and by planners who can either refuse planning permission or make it conditional on the developer building flood defences.
But it will be of little consolation to people who already live in areas which have a history of flooding.
Flooding has increased as more houses are built and it is expected that climate change will also put more areas at risk.
