Langstone Flood and Coastal Erosion Risk Management (FCERM) Scheme

Descriptions

Havant Borough Council (the council) has undertaken market engagement for the construction delivery of a Flood and Coastal Erosion Risk Management (FCERM) Scheme at Langstone, Havant, Hampshire, UK (Langstone Coastal Scheme). Works are required to deliver the Scheme that covers approximately 1km of tidal coastline in Havant, providing increased flood and erosion risk protection to 53 residential and 4 business properties, critical infrastructure including the A3023 (the only highway access to Hayling Island) and a number of heritage assets. The flood defences have been designed with a 50-year design life and to provide a present day, 1:200 year (o.5% Annual Exceedance Probability (AEP)) standard of protection against tidal still water level. The frontage is popular with locals and visitors due to its unique setting between two harbours and is an important area for cultural heritage, with six listed buildings and two Conservation Areas. There is a network of footpaths which also features the historic Wadeway, Solent Way and Hayling Billy Line (which also doubles as a cycle route). There are also two pubs in Langstone (the Royal Oak and the Ship Inn) and the harbours are popular for watersports. The council is proposing an initial contract period for delivery for the works of 2 years and 7 months, A longer term or additional extension periods may be required, subject to future plans for the works. The total estimated value of the Scheme is between £12million and £14million.
