Enough sand to fill 50 Olympic swimming pools has been pumped on to the beach at Dawlish Warren in a project to protect the vulnerable main railway line and thousands of homes.
The £14 million scheme has already raised parts of the western end of the beach by up to three metres since the beginning of June.
The work was timed to happen between June and August to protect important species of birds and to protect fish movements in the Exe estuary.
Work on the western end of the beach has finished a month ahead of schedule.
A similar amount of sand will be added to the eastern end of the beach by the end of August.
The estimated economic benefit of the warren continuing to shelter communities and the main railway line from storms has been calculated at around £158 million.
As well as providing an improved beach for visitors to enjoy, the increased sand levels will reduce damage to the sea defences and help the sand dunes to grow and roll back naturally.
Richard Cox, project manager for the Environment Agency, said: “The good news is we’ve completed the beach recharge at the western end of Dawlish Warren well ahead of our original schedule which tied in with the start of the summer holidays at the end of July.
This innovative scheme continues to be a balance between enhancing the natural environment whilst performing a flood defence function to protect communities at Dawlish Warren and in the Exe Estuary.
Beach goers can now reap the benefit of an improved beach at the western end and
“Once the scheme is complete we’ll have reduced the risk of flooding to more than 2,900 properties around the Exe estuary.”
The dredger Mahury, which has been collecting sand from Pole Sands, just offshore from Dawlish Warren, will stay in place until beach replenishment is complete.
Humphrey Clemens, Teignbridge District Council’s executive member for housing and planning, said: “This is excellent news for residents, traders and visitors, and it is even better news that the recharge work for the main beach has been completed ahead of schedule.
“Credit should go to the teams on the ground carrying out this work.
BMM the contractor, alongside staff from Teignbridge and the Environment Agency. Importantly, thanks go to the many residents, traders and visitors for their patience and understanding so far.
“The safety and interests of the public have always been our main consideration throughout the works and many have been very positive and genuinely interested in what’s happening.”
There’s still work to do with recharge continuing on a section of the beach past groyne 6 but it’s progressing well. Dawlish Warren beach is looking wonderful and the area will now benefit from a multi-million-pound investment in flood defences that provide a modern standard of protection but also help preserve the beauty of this special place.
Since work first started in January, 1,200 metres of stone filled gabion baskets have been removed from the warren.
The timber groynes have been refurbished, extended and replaced to help hold sand on the beach.
More than 200 new seven-metre long kingposts have been installed to form new groynes and more than 1,500 new planks have been installed to raise the groynes to suit the new beach levels.
Construction of a new revetment between groynes three and four will be complete before the school summer holidays.
Work on the new “sandbag” defence buried deep under the dunes at the narrowest point of the warren (the Neck) will continue through the summer.
Giant bags are being pumped full of sand and water which drain to create compacted sand bags up to 2.85 metres high.
When finished, the bags will be buried in the back face of the dune. This structure is designed to reduce flood risk behind from the most severe of storms and prevent the warren breaching along this vulnerable section.
The main construction works are due to be finished by October.
