The Environment Agency is set to begin a £75 million project to keep homes and businesses in Canvey Island protected from flooding.
Much of Canvey Island lies below the daily high-water level in the Thames Estuary. The tidal defences play a critical role in reducing the risk of flooding to people, property and infrastructure on the island.
A 3 kilometre stretch of the island’s existing tidal flood defence revetment will be renewed on its southern shoreline between Thorney Bay and the Island Yacht Club. Sections of the current revetment over the project area date back to the 1930s and need replacing.
Once completed the island’s tidal defences will continue to provide protection for 6,097 properties on the island for another 50 years. The works will also take into account the effects of rising sea levels due to climate change.
As well as refurbishing the existing tidal defences, additional enhancements will be made to the Canvey Island shoreline. These will include improved public access along the seaward walkway.
New steps to the beach and foreshore as well as project information boards will be installed. The surface of the pathway along the landward side of the seawall between Thorney Bay and Chapman Sands will also be improved.
Flowering grass seed mixes will be planted. This is to improve biodiversity on the defence and rock pools will be created to boost habitat in select locations along the foreshore.
The works are part of the Thames Estuary Asset Management (TEAM) 2100 Programme. This is a 10 year capital investment programme to refurbish and improve existing tidal flood defences. As the single largest flood risk management programme in the UK, the TEAM 2100 Programme is refurbishing, repairing and replacing defences in the Thames Estuary where required.
James Mason, Operations Manager for the Environment Agency, said:
“This project is essential to managing the risk of flooding for thousands of people, homes and businesses on Canvey Island.
“The existing revetment along the southern shoreline is starting to reach the end of its useful life. This investment in Canvey Island’s tidal defences will ensure they continue to benefit the community on Canvey Island to 2070.
“We are already seeing the impacts of climate change in the UK. Which is why schemes such as this are needed.
Contractors working on behalf of the Environment Agency will begin setting up site from January with work beginning on the tidal defences from late March. The project is expected to take until summer 2025 to complete.
