The Environment Agency is working with Coast to Capital Local Enterprise Partnership (LEP), Adur District Council and West Sussex County Council to reduce the risk of flooding to Shoreham-by-Sea and Lancing.
The scheme will reduce the risk of flooding to over 2,300 homes and 169 commercial properties by significantly improving the standard of existing tidal defences in Shoreham-by-Sea.
The £32 million project is partnership funded, with a £23.8 contribution from government attracting partnership contributions from West Sussex County Council, Coast to Capital LEP, and some private developers through Adur District Council.
The Environment Agency is working in 7 of the 10 reaches along the River Adur.
At W2, concrete work on the slipway is well advanced and work to prepare the riverside surface for installation of the flood defence is progressing well. The first panes of flood glass have been installed.
At W3, piling works are well advanced behind houses at the eastern end of Riverside Road, and behind the boatyard. Concrete works behind the Riverside pub are well underway.
At W4, the majority of the wall is nearly finished.
At W5, vegetation clearance work in anticipation to start construction in January 2018.
At W6, the flood defence is almost complete (excluding the area next to the railway bridge which we cannot complete until Network Rail finish maintenance to the bridge). The handrail needs to be installed before the area can be reopened to the public.
At E1, the flood defence between Star Gap and Oyster Quay is nearly finished. Work at the Bridge Inn and Toll House is expected to start later this year.
At E3, the earthworks are well advanced and the wall is nearly finished. Work on the earthworks along the Downs Link north of the Amsterdam pub resumed on 14 August 2017, and is expected to be complete in October 2017. The section of defence closest to the railway bridge will be completed once Network Rail finish maintenance to the bridge.
The risk of flooding to coastal settlements around the UK is high and increasing due to sea level rise and to an increase in extreme rainfall events from the effects of climate change. The Environment Agency has carried out extensive modeling to determine the likely extent and range of the potential flood events over the next 100 years.
The current flood defences in the Adur estuary do not provide a high enough level of protection, and in places are in poor condition. This leaves Shoreham-by-Sea, Lancing and the surrounding areas at risk of flooding. The Environment Agency has been developing a major improvements scheme called the Shoreham Adur tidal walls. The scheme will provide protection for extreme events with 0.33% probability (1 in 300 year) of occurring in 1 year, allowing for 50 years of sea level rise.
The scheme is separated into 10 reaches, or lengths of the estuarine bank. The design of the defences varies between the reaches as they have different characteristics and are subject to different pressures and potential flood impacts.
The Environment Agency held consultation events in 2014 and 2015 to gain feedback on the designs. They have taken the feedback received on board and have incorporated changes into the detailed designs. The feedback has included recommendations from the Environmental Impact Assessment, input from various experts and consultation with stakeholders and the local community.
The Environment agency has a visitor centre located in Beach Green car park in Shoreham. Angela Spinks, who is the Public Liaison Officer for the project, is based at the visitor centre weekday afternoons (Monday to Friday) from 12pm to 5pm.

The Environment Agency is working in partnership with West Sussex County Council and Adur District Council to design and build the new defences. The Coast to Capital Local Enterprise Partnership has also contributed funding to the scheme.
