The Environment Agency has raised concerns that without substantial financial investment totalling billions of pounds, Lincolnshire’s coastal flood defences will likely be rendered ineffective by 2040. Such a scenario could lead to considerable flooding in areas such as Mablethorpe and Ingoldmells, with expected water depths reaching 4ft and 5ft respectively.
Recent disclosures at a county council environment committee meeting revealed that approximately 90% of defences along a 30-mile span from Saltfleet to Gibraltar Point are at risk of failing within the next 20 years. Deborah Higton, the Environment Agency’s flood risk manager, highlighted the critical nature of the situation, especially as the region’s position below sea level places it in heavy reliance on these defences to safeguard 20,000 homes and 38,000 stationary caravans.
Councillor Tom Ashton emphasised the threat of ‘stagnation and decline’ in local holiday destinations without the necessary investment. He further mooted the possibility of a ‘managed retreat’ if the required funding is not secured in time. Currently, the Environment Agency allocates between £10m and £15m each year on sand replenishment activities. However, Higton suggests this strategy may become inadequate in future.
The Agency’s objectives are to devise a masterplan by 2028 and secure the necessary funding by 2036. Councillor Danny Brookes demonstrated mixed feelings over the matter – a concern for the situation but optimistic about the council’s commitment to take action. This sentiment follows the dissolution of the flooding committee by the Reform-led authority, which had led Sean Matthews, council leader, to enhance efforts towards addressing flooding.
Revisiting the historical significance of the 1953 North Sea flood which culminated in 43 deaths along the coast, underscores the severity of these warnings. Despite the government’s recent commitments of additional funding for the area, including nearly £11.3m, the necessity for an immediate and comprehensive course of action remains a priority.
