Next phase at Warren begins

By Ellen Grindley in Environment

WORK to replace groynes at Dawlish Warren beach is continuing.

Over the last few weeks, a piling rig has been working at the far end of the beach installing new timber kingpost piles for the new groynes.

This has now been completed and the piling rig has been removed ahead of schedule.

Timber work will now continue on the new and existing groynes during the next few weeks in preparation for the beach recharge in June when sand will be imported to replace eroded material.

The £14 million project, being run by the Environment Agency, is underway to protect the Warren and neighbouring communities and reduce the risk of coastal flooding.

Work is only being carried out at low tide to avoid disturbing over-wintering birds on the Warren.

So far, porous concrete units are being placed to form the new revetment and later in the year, new steps will be installed east of groyne three, replacing those damaged in February’s storms.

The first phase of work to remove the stone-filled gabion baskets was completed in March.

The baskets were failing in numerous places and prevented the dune from behaving naturally.

To minimise erosion of the dunes before the beach recharge in the summer, temporary protection measures have been put in place.

Temporary sand-filled bags have been placed in front of the dune which will be removed before the beach recharge.

During the summer the beach will be recharged with new sand so the higher beach levels will protect the dunes.

The Dawlish Warren Beach Management Scheme began in January after the Exe Estuary flood and coastal erosion risk management strategy identified that the spit at the Warren was at risk of being breached as a result of rising sea levels and storms.

This would increase the risk of flooding to the main railway line and villages along the estuary including Starcross and Cockwood.

The scheme will allow the sand spit to continue to act as a barrier to storm waves, improve the quality of the beach and allow the dunes to recover.
