SEA defences along a stretch of vulnerable coastline are set to be improved to protect more than 300 homes.
New sea walls are to be built at Selsey in West Sussex under a £10m scheme by the Environment Agency.
A sea wall measuring more than half a mile was completed earlier this year and the new defences would stretch a further four miles.
The scheme would protect the only road into the seaside town.
Selsey saw major flooding in 2008 when waves breached a sea wall.
The scheme would cover an area the size of 300 football pitches.
Andrew Gilham from the Environment Agency said: ‘We have now completed the final design and are working hard to begin construction in the autumn.’
The area is one of the stretches of coastline most at risk of flooding in southern England.
A public consultation has been launched.
