It is hoped that the work will protect more than 10,000 homes
Tonnes of gravel have been “rainbowed” on to the foreshore in Portsmouth in the first stage of a £100 million sea defence scheme.
The dredger vessel Sospan Dau is spraying 5,000 square metres of gravel between Clarence Pier and the Spur Redoubt to create a temporary working platform to enable the work to begin.
The new defences will stretch for 4.5km (2.8 miles) from Old Portsmouth to Eastney, and are aimed at reducing the risk of flooding to more than 10,000 homes and 700 businesses.
In the next two to three weeks, the dredger will place about 18,000 square metres of material to create a second working platform between the Spur Redoubt and the Saluting Platform.
