Forton Coastal Defence Scheme

Following the River Hamble to Portchester Strategy, the end of Forton Lake was highlighted as one of three priority areas for a flood scheme. 

Since the strategy, a design has been developed, with a reinforced concrete wall and floodboards as the proposed defence for this area. The defences are designed to protect against a 1 in 100 year until 2060 (this is a 1% Annual Exceedance Probability (AEP), which means a flood of such magnitude has a 1% chance of occurring in any given year). 

The project is now at a stage where construction can be expected to commence in spring 2024, providing protection for 211 residential and 16 commercial properties from coastal flood risk.
