Team Van Oord has started work on phase one of a £44m, 10-year flood protection scheme for the north of Portsea Island which will reduce the risk of coastal flooding and erosion to the area over the next 100 years.
The contract has been awarded to Team Van Oord by the Eastern Solent Coastal Partnership, and made possible by funding awarded to Portsmouth City Council by the Environment Agency.
Portsea Island is a small, low-lying island which contains a large proportion of the city of Portsmouth. It is the third largest (by population) of any island in the British Isles after the mainlands of Great Britain and Ireland, and has the highest population density.
The first phase, known as the Anchorage Park Scheme, is valued at £6m and involves the construction of 1.4km of coastal defenses along the north of Portsea Island between Ports Creek Railway Bridge and Kendall’s Wharf.
This is the first stage of the multi-million pound flooding and coastal erosion risk management scheme being developed across the north of Portsea Island. The wider scheme will reduce the risk of flooding and erosion from the sea to 4,200 homes, 500 businesses and critical infrastructure, over the next 100 years.
Initial site preparation work involving the removal of vegetation has been completed and phase one construction works began on 5 May and are expected to continue until October 2015.
The site has been set up with compounds, a haul route and site security, and work is underway building earth embankments, placing rocks and delivering materials to the site.
The design of the defenses incorporates ideas from local residents, offered during consultation events held last year. More than 200 local residents attended the two events, and of those who filled in feedback forms, 94% said they fully supported the scheme.
Once the defenses are built, the area will be enhanced through an extensive replanting program. This will increase the diversity of plants in the area, improving the current ecosystems and habitats for wildlife.
