A report into flooding at the Glasdir Estate in Ruthin has found that a combination of factors caused the flooding of more than 100 homes.
The report, produced by Environment Agency Wales for the Welsh Government, concluded that;
- debris blocking culverts stopped flood water from draining to the floodplain on the other side of the dual carriageway
- gradients on the opposite side of the culvert meant that flood water could not drain to the wider floodplain and flood relief channel
- heavily saturated ground in the lead up to the event as well as the sheer length of time the river Clwyd was in flood were also important factors
The report which is being distributed to the homes that were affected concludes that the earth bund which protects the Glasdir estate was overtopped due to these factors.
The Agency’s flood experts produced a model of the event to replicate the flooding on 27 November.
An investigation of the site, evidence from eye-witnesses, and photographic evidence showed that
the culverts would need to have been 85% blocked in order to cause the flooding of the estate.
The report will now be shared with relevant bodies and organisations to reduce the risk in the future.
Denbighshire Council have relocated 4 CCTV cameras to provide further reassurance to the public in the areaswhich were most affected by the floods.
Denbighshire's Cabinet Lead Member for Environment, Councillor David Smith:
"The cameras will help provide reassurance to owners of empty properties and act as an additional deterrent to would-be criminals or anyone hoping to take advantage of potentially vulnerable home owners and families in the months ahead."
People flooded out of their homes in St Asaph last month talk to North Wales reporter Ian Lang about their new lives. They've been given free accommodation in a holiday camp for Christmas.
Following the recent flooding in St Asaph, almost 20 households will be forced to spend the festive period in temporary accommodation.
Significant damage to numerous properties across Denbighshire has meant that some residents have spent the last few weeks at the Robin Hood Holiday Camp in Rhyl.
Of all the properties flooded, 17 were damaged to such an extent that their occupants will not be able to move back until 2013.
The floods which hit Ruthin and St Asaph earlier this month caught many by surprise but residents on the Glasdir estate were given warning thanks to local postmen.
An on duty-postman summoned help from some of his colleagues to try to save valuables and check people were ok.
Today, Welsh Secretary David Jones went back to say a personal thank you. Ian Lang was with him.
It's normally the postie's job to deliver gifts at this time of year but today a postman in Ruthin will be the one receiving a special delivery.
Following the floods earlier this month, Welsh Secretary David Jones, will visit the Glasdir Estate in Ruthin to offer his personal thanks to the postman who summoned help from the local sorting office as he began to see the water rising.
Eleven staff came out to help residents save their valuables and check that people were safe.
As a gift to say thank you the Welsh Secretary will give the staff a bottle of House of Commons scotch.
The A494 has reopened in both directions after the ice earlier between the B5105 Mwrog Street (Ruthin) and the A5104 (Clawdd Poncen).
A charity football match is being held this evening to raise money for the flood victims of St Asaph.
It has been two weeks since floods destroyed homes and businesses in the city and elsewhere, with hundreds facing homelessness this Christmas.
St Asaph City's side will face a team made up of Rhyl Athletic and Prestatyn Town players.
There are calls for more support for the many families who were driven out of their homes in the St Asaph and Ruthin floods. Many of them didn't have full insurance and even those with cover face months in temporary accommodation.
There are also fresh fears about cowboy builders targetting the most vulnerable, as Ian Lang reports.
