Seaton's coastal protection scheme will aim to improve the existing revetments and construct new defences

Royal HaskoningDHV to complete outline design and business case for funding

Now that the Seaton Beach Management Plan has been adopted by East Devon District Council (March 2018), Exeter based coastal engineers Royal HaskoningDHV have been appointed by East Devon to complete the outline business case for a coast protection scheme for the town. The outline business case is due to be completed this Autumn.

The scheme, which is a recommendation of the Seaton Beach Management Plan, aims to reduce the risk of erosion to properties and infrastructure to the West of the town between Seaton Hole and West Walk by improving the existing revetments, and constructing a new defence between the existing rock revetment and West Walk.

The outline business case will involve more detailed surveys, investigations and modelling of waves, which will enable the outline design to be completed, costed and summarised in a report for approval by the Environment Agency so that Government funding for the works can be accessed.

Detailed topographic surveys of the existing defences using conventional techniques, as well as a drone, will start shortly and over the coming months investigations into the beach that lies directly beneath where new defences will need to run will also be undertaken, so that there is a good understanding of the location and depth of rock on which any structures will need to sit.

Councillor Marcus Hartnell, Stakeholder Group Chairman and deputy portfolio holder for the Environment, said:

It’s great to see East Devon taking on board the recommendations from the Beach Management Plan and committing the funding to move a coast protection scheme for Seaton forward so we can access government funding.

Alex Lee, Technical Director for Royal HaskoningDHV, said:

We’re pleased to be working on this project with East Devon, drawing on our experience at Seaton in the 1990s as well as our more recent work at Sidmouth and elsewhere around Devon and Cornwall.
