How we plan to manage our shoreline

You can find the coastal management policies for Brighton & Hove in the Southdowns shoreline management plan. This plan covers the coast from Selsey Bill to Beachy Head. 

We created 2 strategy studies from this plan which look at shorter sections of the coast. The strategies cover:

  • Brighton Marina to Saltdean
  • Brighton Marina to River Adur

These strategies suggest ways we can put the shoreline management plan in place.

We did coastal strategy studies for both strategies. This helps us decide how we should manage our coastline now, and in the future.

What a coastal strategy study is

A coastal strategy study looks at how a length of coast will change over the next 100 years. It looks at how to manage the human and natural factors that will influence it. 

It explores what kind of defensive measures we need to deal with these changes. It then looks at whether they’re affordable. 

It usually includes a programme of coastal management works for the 100 year period.

Who pays for it

The Environment Agency pays for the study. The completed study must be approved by them. 

Usually a combination of sources will pay to put the strategy’s recommendations in place. It can include grants from the Environment Agency and contributions from those who’ll benefit from the defences.

If the Environment Agency agrees to give us any grants, they set aside the money for a future year in their capital investment programme. We can then submit a bid for the money as that year approaches.

Brighton Marina to Saltdean strategy 

The strategy recommended keeping up the defences between Ovingdean Gap and Saltdean. It also recommended reconstructing the defences between Ovingdean Gap and the Marina.

Brighton Marina to River Adur strategy

The coastline covered by the Brighton Marina to River Adur strategy extends from Brighton Marina to the mouth of the River Adur. 

The area includes sections of coast that we manage, and sections managed by Adur District Council.

The Environment Agency approved the study. They set aside some grant money for the first stage of improvements to the coast defences. The works will begin during 2020 to 2021.

The Environment, Transport and Sustainability committee approved the study in July 2014. Download the committee report.

This report identifies where we need to do the improvement work.

How we take climate change into account

All the studies that we do take into account the government's latest sea level rise guidelines.

Information on the changing climate is put together on a global scale by the Intergovernmental Panel on Climate Change (IPCC). 

Their predictions for England, along with research from a range of domestic organisations, are put together for Defra (Department for Environment, Food & Rural Affairs) as part of UKCP09.
