More information: The Scheme

The Scheme aims to:

1: Manage flood risk for people, homes, businesses and infrastructure

2: Create a better place through environmental enhancements in the local area

3: Embed low carbon technology and approaches in line with the EA’s Emission Strategy

4: Deliver Social Value through working in partnership

5: Support sustainable growth in the areas we are reducing flood risk

A breach (a gap in the defence caused by the beach eroding in a storm) could allow the sea to flow inland at high tide and cause extensive damage with lasting impact on lives and livelihoods. Due to the low elevation of land behind the defences a breach at any location along the 15km coastline may flood a much wider area.

The map below shows the area (flood cell) at risk of flooding following a storm breach if we don’t improve the defences to provide the same standard of protection as sea levels rise. The flood area increases over time based on predicted sea level changes.

The frontage has been managed as two separate sections since 2000. Eastbourne Borough Council have managed the coastline between Holywell and Langney Point. Pevensey Coastal Defences Limited (PCDL) have managed the section from Sovereign Harbour to Cooden Beach on behalf of the Environment Agency.

In 2025 the PCDL contract ends, after which the Pevensey Bay to Eastbourne Coastal Management Scheme takes over. There will be no gap in the management of this coastline.

From 2027 the 15km frontage will be managed as one section reflecting the connected nature of the flood cell to allow a more holistic management approach to be taken.

The below chart gives an overview of the indicative scheme timeline. A more detailed version can be viewed in the full project timeline.

Scheme timeline overview 

 

Climate change will have a wide range of impacts in coastal areas and there is no single solution to increasing resilience to flood risk. Forecasts suggest that sea level will rise by up to 1.15m by 2100 but uncertainties remain.

Taking a phased approach (referred to as adaptation pathways) allows interventions to be taken at the right time, avoiding the cost of acting too early or too late. We can put in place defences that reduce the risk of flooding and erosion in the medium-term, whilst planning for the long-term, so that we are ready to deliver protection against a higher sea level when that becomes necessary. It means we stay ahead of, and on top of, the risk whilst not providing over-engineered solutions in the present. This also means we can keep the things we love about life along the coast for as long as possible whilst we work out a new relationship with higher sea levels.

We have funding in place to develop the scheme in more detail. We aim to secure funding to deliver each phase from government. This funding is known as Flood and Coastal Erosion Risk Management Grant in Aid (FCERM GiA). Eastbourne Borough Council is a contributing partner and other funding sources are being sought.

3. ‘Standard of protection’ is defined by the size of storm event that the defence is designed to withstand. Storm size is expressed as a probability of that event happening. So a winter storm that we’d expect to occur every year would be a 1 in 1 year or 100% occurrence (even though we may have some years without one and others with more than one)

Beach management by PCDL has been carried out in accordance with a 25-year Environment Agency contract, which is called a Flood Defence Service Agreement (FDSA). This was the first sea defence project in the world to be funded as a Public Private Partnership (PPP).

PCDL has delivered a high level of flood protection over this timeframe, and no significant flooding has occurred over the last 25 years.

The FDSA has effectively protected homes, businesses, transport links and services from coastal flooding and erosion.

The 8.5km beach managed by the FDSA. It stretches from Sovereign Harbour in the West to Bexhill in the East on the South Coast of England. 

 

The PCDL contract concluded at the end of May 2025. Since June 2025, the Environment Agency has taken over management of the 8.5km Pevensey frontage, with our contractor, VolkerStevin, carrying out operational beach activities. The Pevensey Beach Manager -  Amber Carr - leads day-to-day beach operations.

This Short-term Phase will continue to provide the same Standard of Protection as the last 25 years for the Pevensey Bay community. The coastal defences are designed to withstand a really extreme storm - which has only a 0.25% chance of happening in any given year, without a breach. They also prevent significant water flowing over the defences in an extreme storm - which has only a 0.5% chance of happening in any given year.

We are managing the beach in a similar way to PCDL, you may notice more workers on the beach but there is little difference in the activities which include:

Shingle reprofiling

Shingle is moved by machinery to reshape the beach after waves have removed it, to ensure the beach crest remains wide enough.

Shingle reprofiling

 Recycling

Shingle that moves due to longshore drift temporarily builds up in some places so it is moved back along the beach in large dumper trucks.

Shingle recycling

 Bypassing

This means moving shingle by road in dumper trucks around Sovereign Harbour.

Bypassing process

 Recharging

The shingle lost from the beach is replaced using the Sospan Dau dredger to add shingle from offshore to the beach.

Beach surveys

This involves monitoring the size and shape of the defences to decide when beach management work is required.

We are continuing to proactively engage with local residents and community including the Pevensey Bay Coastal Community Group. 

Throughout the Short-term phase (2025-2027) Eastbourne Borough Council will continue to manage the beach between Holywell and Langney Point.

We will align with plans for the medium- term phase as they develop and when the Medium-term Phase starts in 2027, the Eastbourne and Pevensey Bay coastal frontages will be combined and managed together under one project.

By 2040, sea levels are predicted to rise by approximately 10cm^{1, 2}. Over the next 100 years, sea level is expected to rise far more. This means more substantial change is likely to be needed in the longer term.

We have reviewed existing beach management processes and structures to consider different flood protection options (the longlist). These options have been assessed against multiple criteria including:

• Ability to provide flood protection
• Affordability
• Environmental impact (including carbon emissions and biodiversity)
• Public and stakeholder feedback
• Lock in (where choice of an option for the medium-term, restricts or prevents option choices in the longer-term)

Our research, modelling and engineering calculations show that we can deliver the desired standard of protection without any major changes to our approach in the medium-term.

We have reviewed existing beach management processes and structures to consider all the possible flood protection options. These options have been considered and assessed against criteria which factored in what is best for the environment, people and place and resulted in a preferred option of Beach Improvement Works being selected. We are continuing to explore the viability and appetite individual for Property Flood Resilience (PFR) measures to act as secondary coastal protection for some properties.

The preferred option for the medium-term project involves a combination of improvements to current beach management practices including:

• Beach optimisation
• Shingle maintenance
• Groynes
• Beach monitoring
• Property Flood Resilience (PFR)

Beach design

This part of the approach is about improving and updating the size and shape of the beach, with the aim of reducing shingle flood and erosion risk. In turn this approach also aims to result in fewer machines to move shingle on the beach in turn also significantly reducing carbon emissions.

Shingle maintenance

Beach material constantly moves along the coastline by the action of the waves, which occurs to a greater extend during storms. The movement of material changes beach size and shape and so needs to be returned to maintain the required design. A large amount of heavy machinery is used to achieve this and reducing the number of machines and alternative fuels such as hydrogen or battery powered are being explored. The preferred option aims to ensure that each section of beach is correct amount of beach material to protect communities.

Groynes

These wooden structures capture material as it moves along the coast by natural processes. They help with shingle maintenance by storing it closer to where it is needed. Work to both repair and enhance some existing groynes is planned to ensure their performance is maintained.

Beach monitoring

Improvements to surveying and monitoring practices are needed to understand how beach shape and size change over time. This data informs what maintenance is needed and how urgently it should be implemented. There is a large amount of data available already, but the project will embrace new technologies to advance our approach and further minimise flood and erosion risk to homes and businesses.

Property Flood Resilience (PFR)

All properties on the coast and beyond are protected to a high standard by the beach. However, some, especially those on or very close to the beach, may benefit from further modifications called PFR³. It is very important to be aware that PFR measures are over and above the required level of protection and act as a secondary line of protection for some homes and businesses. These measures could include the installation of smart air bricks and non-return valves, flood doors and barriers. PFR measures are being considered but further work needs to be carried out through the design stages to better understand the property flood risks before we will have any further specific detail on this.

The project team are continuing to work closely with stakeholders and involve communities throughout the development of the scheme. Now that a preferred option has been selected for the medium-term project, we are working to develop the detail. We have shared the outline designs during autumn 2024 and invited you to share your thoughts and feedback with us.

A presentation detailing the designs for Phase 1 is now available for you to view in the video section on the side panel of this webpage.

We will also be seeking significant Grant in Aid Funding from HM Treasury to proceed to finalising designs and carrying out the works from 2027.

We are continuing to collect information on community aspirations for the coastline. Our findings from a survey we ran in summer and early autumn 2025, including what people value along the coastline and their hopes for the future, will be available early in 2026.

You can also explore our StoryMap to learn about the history of this coastline and review examples of coastal defence approaches from around the world. These types of interventions will be assessed for their economic, technical, and environmental suitability as part of Phase 2.

Our interactive StoryMap brings the coastline to life through maps, images and storytelling. It explains how the coastline has changed over time, the challenges we face and the actions being taken to manage coastal flooding and erosion.

This visual resource is updated as the scheme progresses and offers an engaging way to understand the wider context of the project.
