The Tipner Lake phase of works covers 1.85 km of coastline from the Mountbatten Centre to the Portsbridge roundabout and will take three years to complete. The area has environmental designations that include SPA, RAMSAR, Important Bird Area, SSSI, Designated Shellfish Waters and Bass Nursery Area.
A new, 4m high, reinforced concrete seawall comprising large areas of encasement and sheet pile installation is being built along the entire frontage of Tipner Lake, which will provide a continuous defence and protection against a 1 in 500-year coastal flood event.
A shared footpath and cycleway directly behind the seawall will be reconstructed as part of the works, together with new landscaping, planting and creation of ‘social spots’ that will provide places for people to stop, relax and enjoy the views. A shared use coastal path will be retained and a new network of paths will improve access.
Also included as part of the works is the removal of the 250m Lower Wade Way slipway and causeway and the construction of a new, shorter slipway.
An ornithological watching brief is in place from November 2017 to February 2018, while we undertake some non-piling and site preparation works over the 2017/18 winter period. This was agreed with Natural England to ensure that there is no significant disturbance to the waders and Brent Geese that feed on the intertidal area adjacent to the seawall.
