Canvey Island barriers spanning Benfleet Creek to the north and East Haven Creek in the west. The drainage system consists of sewers, culverts, natural and artificial dykes and lakes which feed seven pumping stations and gravity sluices that discharge the water into the Thames and creeks. Four of the discharge sites are "high flow" stations capable of discharging 600 litres of water per second at any tide level. The levels within the system are managed by a further five "low flow" pumping stations. The Environment Agency's Thames Estuary 2100 flood defence plan includes Canvey Island as one site for alleviating the flood
Canvey Island also home to two Dutch Cottages, one in Haven Road and the other on Canvey Road, which were built during the 17th century by Dutch immigrants working on the sea walls. The cottage at Canvey Road is home to the Dutch Cottage museum. Some of Canvey's lost landmarks include the Goldmine club on Western Esplanade, the original Oysterfleet public house and lighthouse and Cherry Stores. Canvey Island is connected to the mainland in the northwest by two roads with bridges: the A130 (Canvey Way) and the B1014 (Canvey Road). Built in 1972, the A130 (Canvey Way) crosses East Haven Creek
