Highlights from Recent Projects

The first two years to the framework have been a success, with the Environment Agency having recently achieved their four-year national target of having over 300,000 home better protected by March 2021.  

We are supporting flood and erosion risk management targets such as these, as well as other key targets, such as carbon reduction, innovation, environmental enhancement, and improvements to navigation, via the delivery of an exciting project portfolio that include:

  • Thorney Island Habitat Creation – The Thorney Island Habitat Creation scheme aims to allow new intertidal habitat to develop over time to compensate for the loss of this important habitat in Chichester Harbour and the wider Solent.  The creation of this intertidal habitat will provide a variety of benefits for Chichester Harbour including: supporting international designated habitat (SAC and SPA); providing fish nurseries; attenuation of wave energy in the wider Chichester Harbour; filtering pollutants to improve water quality; and carbon sequestration.

  • Lower Mole Flood Alleviation Scheme – The original Lower Mole Flood alleviation scheme construction in the 1980s was designed to reduce the risk of flooding in the lower reaches of the River Mole catchment. The scheme is now reaching the end of its life and consideration is being given to replacing the aging assets or re-naturalisation of the channel.

  • Farlington Marsh FCERM Scheme – Farlington Marshes is a 125ha peninsula of undeveloped coastal land, situated between the city of Portsmouth and Thorney Island. A 4km sea wall protects low lying land from tidal inundation. Farlington Marshes is an internationally, European and nationally designated site (SAC, SPA and RAMSAR) comprised of coastal grazing marsh and lowland meadow.  The scheme consists of the replacement and upgrading of the defences with the key project objectives for a suitable sustainable solution that will protect and enhance both the functionality of the protected sites within the Natura 2000 (N2K) network and the recreation and amenity value of the site, minimise carbon and also help to develop strong working partnerships with the key stakeholders in the area.

  • Medway and Rye Navigation packages – The packages include works on the River Medway and at Rye Harbour.  The River Medway package include the refurbishment of a series of lock structures on the river, together with works to adjacent automated sluices and radial gates.  Works also include the development of new landing stages and pontoon systems.  In Rye we are developing the detailed design for the replacement of a 150m long jetty, reconstruction of rock revetments at the entrance to the harbour, together with other improvements within the harbour.

  • Pevensey SSSI improvements – The Environment Agency are delivering four schemes in the Pevensey Levels to ensure adherence over the next 25 years to a Water Level Management Plan (WLMP) that is critical for the functionality of 3,600ha of Pevensey Site of Special Scientific Interest (SSSI) and internationally designated wetland – Pevensey SAC and Ramsar.

  • Pevensey to Eastbourne Coast Protection Scheme – The Environment Agency currently manage the approximately 9km of beach at Pevensey to provide a 1 in 400 SOP against breach from coastal flooding. This has currently been managed through a 25-year PFI scheme that is being delivered by Pevensey Coastal Defences Limited (PCDL). The current scheme is due to expire in 2025, hence a new scheme will need to be put in place to manage the coastal flood risk.  The remaining approximate 6km section of the flood cell is currently managed by Eastbourne Borough Council (EBC) and also consists of a beach management scheme and groyne field. While acting as a key FCERM asset the scheme provides additional amenity benefit to the town and helps the local tourism economy.

  • Brighton Marina to River Adur Coast Protection Scheme – This scheme is located on the south coast, Sussex along the open coast of Shoreham and Brighton. The scheme frontage stretches for approximately 11km from the River Adur in the West to Brighton Marina in the East. Works within the first phase (15 year benefit period) are located in six key areas.

  • Asset Recovery Programme – The team is delivering a programme of works includes the assessment, design and repair of a number of flood defence assets in the Environment Agency Solent and South Downs, and Kent and South London areas that suffered damage in the winter storms of 2019 / 2020.

  • Milford-on-Sea Seawall – The project involves supporting New Forest District Council with the development of the retrospective business case to secure GiA funding for the recently installed emergency coastal defences at Milford-on-Sea.
