One of Cornwall’s most iconic seafronts is being protected and improved as Cormac Solutions starts work on a £3.7M sea defence project at Long Rock Beach, near Penzance.
Cormac will install 300m of new rock armour sea defences on Long Rock Beach and raise the water level in Marazion Marsh. This will, when coupled with dredging and a silt trap, increase the water storage capacity and create 3.9ha of improved wetland habitat.
Currently the coastal defences consist of a mix of natural sand dunes, masonry sea walls, cladded revetments and intermittent rock armour, in varying states of repair and condition.
The scheme will repair and improve the existing walls and the rock armour will be installed at the most vulnerable section.
The work, which is being carried out on behalf of Cornwall Council, will be completed by September this year and will provide coastal protection to the Great Western Railway mainline and A30, as well as 295 residential and 65 commercial properties.
Once the area is protected a longer-term strategy can be developed to provide protection to the coastline, the council has said.
Cornwall Council’s portfolio holder for environment and public protection Sue James said: “These works will protect the historic Long Rock seafront while improving access to the beach and protecting the adjoining wetlands.
“They will have a significant impact on protecting Cornwall’s natural environment and a more resilient coastline will allow the area to attract more investment and regeneration.”
Ward Williams Associates is the project and cost manager for the scheme.
