Work to repair the coastal defence at Llanbedr, near Harlech, has been completed after high tides and stormy conditions caused a 50 metre breach in the embankment earlier this year.
Specialist teams from Natural Resources Wales have been undertaking emergency works over the last 12 weeks to build an access road to the breach and to fill the gap using 15,000 tonnes of boulders, clay and soil.
The new section of the bank has been reinforced with a solid clay core, strengthened with boulders and covered with topsoil to bring it back to the required level of flood protection.
Engineers will now monitor its performance over the coming months to make sure it continues to stand up to the tide effectively.
Prior to the repairs being made, five houses, the airfield and thousands of acres of agricultural land were being flooded twice a day with the incoming tides.
In the immediate aftermath of the storm, Natural Resources Wales arranged for a helicopter to position giant, industrial-sized sandbags to fill the gap ahead of further predicted high tides.
A spokesperson from Natural Resources Wales said:
“We’d like to thank the people of Llanbedr for their support while we’ve undertaken these essential works.
“These were the worst storms to affect the Welsh coastline in many years, causing damage, disruption and flooding to many people – the memories of which remain fresh in the minds of those affected.
“As we have seen in Llanbedr, we cannot always prevent flooding from happening, but where we can we will take action to reduce the risk to local communities.”
