This project will maintain the existing high level of tidal flood risk protection to thousands of homes, businesses and infrastructure on Canvey Island into the future, a key aspiration of the Thames Estuary 2100 Plan. It will protect the tidal defences against erosion and extend their useful life to 2070 in light of increasing sea levels due to climate change.  The works are planned and delivered as part of the Thames Estuary Asset Management (TEAM) 2100 Programme. This is the single largest investment in Canvey Island's tidal defences since they were raised in the early 1980s

The renewing and improving of the revetment on the seaward face of the tidal defences will take place along a 3km stretch between Thorney Bay and the Island Yacht Club as shown on the map below.

Programme of works and construction

Details of the construction are explained in more depth within the PDF documents at the bottom of this page and key aspects are summarised below:

Duration of project: the construction will take an anticipated two and half years 

Working hours on low-tide: revetment works are fitted into the low-tide window, hence they take place over an approximate 5-hour period, anywhere between 6am-10pm. Detailed timetable is included in each mothly newsletter below. 

Working hours on landward side: construction works on the landward side of the sea wall to take place in regular working hours (8am-6pm Monday to Friday)

Factors affecting phased delivery of two construction teams' work: 

  • Benfleet and Southend Marshes at the eastern end of the project’s extent, which is an internationally important site for habitat and wildlife and is designated as a Special Protection Area (SPA), Site of Special Scientific Interest (SSSI), and Ramsar (a Ramsar site is a wetland site designated to be of international importance under the Ramsar Convention)
  • The western end of the project area contains a very well used public amenity front with beach areas, tidal pools and a host of amenity features and services.
  • Archaeological fieldwork may also be required to mitigate impacts on any buried archaeological remains within the foreshore
  • A main compound, required for duration of the works, to be located at the end of Eastern Esplanade.
  • Satellite compounds will be required for much shorter durations. Three of these sites will be away from the main compound, at Western Esplanade, Eastern Esplanade car park and Beveland Road respectively

Canvey Island is very low lying with ground levels nearly two metres below the daily high tide level in the Thames estuary. This means that the entire island is at risk of tidal flooding which could impact more than 15,000 residential properties and this scheme will directly benefit over 6,000 of those residential properties. This risk is managed by 14 miles (23km) of tidal defences which provide a very high standard of protection and were built in response to the last tidal flood event to impact the island in 1953.
