Canvey Island is located on the north shore of the Thames Estuary, in Essex. Separated from the mainland by tidal creeks, it has a population of 40,000 and is the largest town in the Borough of Castle Point. The island has pockets of local deprivation with some wards among the most deprived in the country, exhibiting poor levels of educational attainment, low income and high health deprivation.
A reclaimed wetland, the 18km2 island sits around 1m below high tide sea level, making it vulnerable to flooding from both sea and surface water. Devastated by the 1953 North Sea Flood which inundated the island and killed 53 inhabitants, the island is currently protected from tidal surges by its 7m high sea wall. However, with rising sea levels and increased storms due to climate change, these defences have been identified in the TEAM2100 programme as an area where improvement works need to be made. The Environment Agency is due to begin this upgrade in Summer 2022.
