How we protect the coastline from erosion

We’re a member of the South East coastal group. The group covers from Selsey Bill to the Thames estuary. The group includes: 

  • district authorities
  • borough authorities
  • unitary authorities
  • county authorities 
  • Environment Agency
  • Natural England

The powers we have to protect the coastline are set out in the Coast Protection Act (1949). 

Over the next 100 years, the rate of erosion for Brighton & Hove's coastline is currently assessed as minor. The Environment Agency has interactive maps showing this information.

There are 2 strategies for Brighton & Hove's coastline. Find out more about our coastal management policies.

Flooding from the sea

The Environment Agency has direct responsibility for sections of coast that are prone to flooding from the sea. 

Coastal defence

The Environment Agency, on behalf of Defra (Department for Environment, Food & Rural Affairs), also has a national responsibility for coast defence. Defra handles coast defence policy.
