Elmer flood and erosion risk management scheme


The shoreline at Elmer, West Sussex has a range of coastal defences such as the offshore rock breakwaters (islands), shingle beaches and rock revetment. These are in place to protect local people and properties from the risk of flooding and erosion from the sea.

Some of these coastal defences (particularly the shingle beach in front of Elmer Sands Boating and Angling Club) are at risk from breach (breaking) and wave overtopping (water passing over the top), especially during stormy weather. This means that the land behind the defences is at risk from flooding and coastal erosion if they are not improved.

The scheme

The Environment Agency is working in partnership with Arun District Council and Elmer Sands Limited to improve the coastal defences at Elmer, to reduce the risk of flooding and erosion to people and property. They have also been working closely with representatives of Elmer Sands Limited, so that they can include local feedback into their plans where possible.

The Environment Agency has identified a ‘preferred option’ which is designed to better protect 325 properties from flooding and coastal erosion for the next 50 years, with an estimated cost over this time of £6.4 million. The preferred option involves extending the existing rock revetment (rock wall) eastwards just beyond the Elmer Rife (approximately 165 metres). It also includes repair work to the existing rock revetment and the addition of shingle (recharge) to some of the bays along the beach.

Community engagement

The Environment Agency will continue to speak to the local community as the scheme progresses. The exhibition boards from the public information events, held in Elmer during August 2018 are available to view here:
