Project Overview

The Benacre & Kessingland Flood Management Project aims to reduce flood risk in Kessingland and the Lothingland Valley while delivering wider environmental and community benefits. Construction began in Spring 2025 and is expected to finish by Summer 2030.

Originally built in 1955, the Environment Agency’s 70-year-old Benacre pumping station near Kessingland has exceeded its lifespan. Adding to these concerns, the Benacre Ness sand and shingle ridge that has historically protected the station is steadily moving north, leaving it exposed to coastal erosion. To tackle this urgent issue, the realignment scheme will construct inland flood defences, including;

  • An embankment spanning the Lothingland Valley to manage tidal flooding and a pumping station to manage river levels.
  • An embankment around Kessingland’s Parkdean Resorts to manage tidal flooding and a pumping station to manage surface water for the village.

The Lothingland station features three 3 meter diameter Archimedes screw pumps that will lift water 4.5 meters over the flood embankment. The flow rate will be as low as 0.75m³/second up to full capacity of 10.2m³/second. This is more than double the current stations capacity accounting for climate change predictions for intense rainfall events. The Kessingland station features one 2 meter diameter Archimedes screw pump that will lift water 4.5 meters over the flood embankment . This replaces a gravity discharge from the village of Kessingland improving water level management back to the village.

The project will be completed by decommissioning and demolishing the ageing Environment Agency pumping station.

Benefits

The Benacre & Kessingland Flood Management Project will provide lasting value to both the local community and the natural environment.

  • Protecting 35 homes, 46 businesses and 600 hectares of farmland from tidal, fluvial and surface water flooding.
  • Securing vital infrastructure, such as the A12, to support the resilience of the regional economy.
  • Providing job opportunities and local business involvement during the construction phase.
  • Creating over 50 hectares of intertidal marsh to support wildlife and act as a carbon sink.
  • Enhancing 52 km of river habitat by removing barriers to eel migration.
  • Safeguarding 11 million cubic metres of freshwater, protecting habitats and agriculture.
  • Undergrounding of 1.8km of overhead power lines within the ‘Suffolk and Essex Coast and Heaths National Landscape’.

By combining engineering innovation with environmental restoration, the project ensures long-term flood protection for Kessingland, the Lothingland Valley and the surrounding area.

History of Benacre Ness

Benacre Ness is a large, mobile sand-and-shingle foreland that has gradually migrated north along the Suffolk coast for centuries, making it one of the most dynamic coastal features in the region. Early maps from the 16th to 18th centuries show a protrusion several kilometres south of its current position, sometimes labelled Easton Ness. More reliable 19th-century mapping captures the feature near Covehithe, later renamed Benacre Ness and from this point onward its steady northward movement becomes clearly documented.

Aerial photography shows that Benacre Ness has continued to reshape itself and the coastline, elongating and advancing more than 1.5 km at its leading edge while its southern edge has eroded more slowly. Its associated offshore shoal, known as Barnard Bank, plays a key role in local sediment circulation and supports the ness’s continued migration.
