Flood, radon and landslides in Newtown
Newtown has no Hazard risk Grade: Irish places under 1,000 residents aren’t graded. The figures below are still its own.

Weather and flood warnings for Newtown
Where to see the warnings in force, and what this page can’t count.
Met Éireann issues yellow, orange and red warnings for rain, wind and coastal flooding county by county; Newtown is covered by County Cork’s.
| Warning | What Met Éireann means by it |
|---|---|
| Yellow | Weather that isn’t unusual but can be dangerous in places: be aware. |
| Orange | Infrequent, dangerous weather that can put people and property at risk: be prepared. |
| Red | Rare, extremely dangerous weather: take action to protect yourself and your property. |
Met Éireann doesn’t publish an open archive of past warnings, so how often warnings have covered Newtown can’t be counted here.
No OPW flood relief scheme protects Newtown
The Office of Public Works’ completed flood relief schemes and the areas each one benefits (OPW open data, CC BY 4.0).
None of the OPW’s completed flood relief schemes has a benefiting area that takes in Newtown’s homes. The OPW builds schemes where the risk to homes is greatest, so most towns have none.
In County Cork, OPW schemes protect parts of 3 other places, including Mallow, Fermoy, Dunmanway.
| Town | Scheme | Designed for | Homes behind it | Away |
|---|---|---|---|---|
| Mallow Cork | Mallow South & West Flood Relief Scheme | 1 in 100 | 2.6% | 25 km |
| Annacotty Limerick | Mulkear River (Ballymackeogh) Flood Relief Scheme | 1 in 10 | 1.1% | 39 km |
| Fermoy Cork | Fermoy South Flood Relief Scheme | 1 in 100 | 6.3% | 40 km |
| Ennis Clare | Ennis (Upper) Flood Relief Scheme | 1 in 100 | 3.5% | 57 km |
| Clonmel Tipperary | Clonmel (North & East) Flood Relief Scheme | 1 in 100 | 7.4% | 72 km |
| Dunmanway Cork | Dunmanway Flood Relief Scheme | 1 in 100 | 14% | 73 km |
Newtown is in the lowest radon band
The EPA’s radon map: for each 10 km square, the estimated share of homes above the national reference level of 200 Bq/m³.
A square where 10% or more of homes are estimated above the reference level is a High Radon Area; 0% of Newtown’s homes are in one. The map is an estimate by area: two neighbouring houses can differ a lot. Too few homes are mapped here, so the figure is the square at the town’s centre.
A test is the only way to know a home’s level: two detectors, left for three months in a living room and a bedroom.

No EPA-licensed site within 5 km of Newtown: the nearest is 5.6 km away
Factories, farms, power plants and waste sites that hold an EPA licence for their emissions, in Newtown and around its centre.
| Site | Licence and activity | Away |
|---|---|---|
| Dawn Meats Ireland t/a Dawn Charleville | Industrial Emissions licence · food and drink | 5.6 km |
| Kerry Ingredients (Ireland) Limited (Charleville) | Industrial Emissions licence · food and drink | 6.2 km |
| Brewery, Chemical and Dairy Engineering Limited | IPC licence | 7.3 km |
| Activity | Sites |
|---|---|
| Food and drink | 2 |
| Not classed in the register | 1 |
An EPA licence sets what a site may release to air, water and land; it doesn’t mark the site as an accident hazard.
Sites holding dangerous substances in bulk come under the COMAH (Seveso) rules, but the HSA’s list of them has no open licence, so upper- and lower-tier sites aren’t counted here.

Get ready for what Newtown faces
What to do, and what to ask before you move.
- Never walk or drive through floodwater: 30 cm of moving water can float a car.
- Move valuables, papers and medicines upstairs.
- Turn off gas, electricity and water if you’re told to.
- Test over three months, in a living room and a bedroom.
- Above 200 Bq/m³, a small sump and fan usually fixes it.
- The EPA sells radon test kits at radon.ie and lists registered contractors who fix high readings.
- Bring in or tie down bins, trampolines and anything the wind can lift.
- Keep away from coastal paths and piers while an orange or red warning is in force.
- Charge phones and keep a torch: fallen lines are the commonest storm damage.
- After the storm, report a fallen line to ESB Networks and keep well clear of it.
- Ask whether the home has ever flooded, and get a buildings insurance quote before you commit: flood cover isn’t always offered.
- Ask the seller or landlord for a radon test result, or test in your first months there.
- Check the address on floodinfo.ie: the OPW’s flood maps and its record of past floods.
What this data can and can’t tell you
- An estimate, not a flood map. Low-lying homes is a TownRatings modelling step: each home’s ground height from LiDAR, against the level of the nearest big river (Strahler order 5 or more), lake or estuary within 1 km, or the sea within 2 km. A home within 5 m of the water’s level, or below 4 m near the sea, counts.
- Flood counts only one way. A high share of low-lying homes lowers the Hazard risk Grade; a low share never raises it, because defences, small streams, culverts, groundwater and flash floods don’t show in ground heights. Below the national median a town scores as the median.
- Defences aren’t counted. Flood defences aren’t taken off: the OPW scheme that protects the most homes is shown instead, with its design standard.
- Measured where the heights are detailed. A town is measured, and counted, only where 80% of its homes stand on LiDAR heights. Elsewhere the page says flooding isn’t measured, never that the town is dry.
- Radon is an estimate by area. The EPA’s radon map gives the estimated share of homes above 200 Bq/m³ for each 10 km square, averaged here over the town’s homes. It says where to test, not what one house holds.
- The sea is measured by height. Homes count as low by the sea when their ground is under 4 m and within 2 km of coastal or estuary water; waves, surges and erosion aren’t modelled.
- Landslide ground is a map of where slides could start. GSI’s susceptibility map rates the ground itself; it doesn’t record past slides or say when one will happen.
- Bathing water is rated season by season. The EPA classes each identified bathing water from four seasons of samples; a rating says how clean the water has been, not how safe it is to swim.
- One town, many streets. Risk is street by street. Check a specific address on floodinfo.ie before you buy or rent.

Questions about flooding and hazards in Newtown
Does Newtown flood?
Too few homes are mapped in Newtown to estimate how many stand low by big water. For a single address, the OPW’s official flood maps and past floods are on floodinfo.ie.
Is radon a problem in Newtown?
The EPA’s map estimates that about under 0.1% of homes around Newtown are above the radon reference level of 200 Bq/m³: a lower share than in 92% of Irish towns. 0% of its homes are in a High Radon Area. The only way to know a house is a three-month test.
How does Newtown compare with the places around it?
Radon estimates around Newtown run from under 0.1% in Charleville to 15% in Buttevant; Newtown’s own is under 0.1%.
