Repairs to an ageing waterfront revetment in Southampton will combine new coastal protection infrastructure with artificial rock pools designed to provide habitat for marine life.1
Southampton City Council has given final approval for work on the Mayflower Park revetment, which protects the city-centre park from erosion and damage associated with tides and port activity.
The structure is more than 100 years old and has deteriorated to the point where substantial repairs are required. The project will install sheet piling and new concrete revetment panels intended to protect the shoreline for decades and reduce reliance on temporary repairs.
Rock pools crafted by students from Southampton schools will also be incorporated into the repaired revetment, with the aim of providing habitat and increasing marine biodiversity.
The approach follows an earlier Southampton coastal defence project at Weston Shore, where rock pools were created in the lower sections of a rock-armour revetment to provide habitat for marine life.2
An additional £3 million has been approved for the Mayflower Park project over the next 18 months. The council attributed the increase to inflation, deterioration of the existing structure being more extensive than originally anticipated, and a shortened window in which piling can take place because of ecological constraints.
Intrusive site surveys are due to begin in early October, ahead of the main repair programme starting in November.
The works will require the closure of the waterfront parking area and parts of the western side of Mayflower Park, although its central grass area and facilities on the northern side will remain open.
Mayflower Park occupies a waterfront site overlooking the tidal River Test and is the city’s only city-centre waterside park.3
Councillor Sarah Bogle, Leader of Southampton City Council, said the works would “secure the future of the waterfront here for many years to come”.
“Once complete, the repaired revetment will continue to protect the park from coastal erosion, while reducing ongoing maintenance costs,” she said.
Southampton’s wider coastal strategy has previously considered steel sheet-pile defences as an option for Mayflower Park as part of managing coastal flood and erosion risk.4
